This paper reviews the successful N'Dama cattle genetic improvement programme implemented in a low input production system at the International Trypanotolerance Centre (ITC) in 1994, in The Gambia. The first part of the paper presents the genetic improvement programme. The second part deals with the analysis of the genetic improvement programme. The success of the genetic improvement programme expressed through genetic progress and the benefits for the farmers is encouraging. Recommendations to strengthen the implementation process in the field are made.

Assessment of diversity is a prerequisite for the management and conservation of farm animal genetic resources. To study the morphological features of Fipa cattle in Southwestern Tanzania, 108 herds were studied. Fourteen body measurements (body weight, body length, height at withers, heart girth, ear length, ear width, horn length, horn-base thickness, horn-base spacing, horn-tip spacing, rump width, rump length, tail length and tail-base thickness) and qualitative traits were recorded from 307 animals. Measurements were classified according to location and animal sex. Both location and sex significantly (P < 0.05) influenced all the measurements, with castrates and bulls superseding cows. Most measurements were positively and highly significantly (P < 0.001) correlated with the body weight predicted accurately from heart girth. The animals had variable colour patterns, but being predominantly red (20.9 percent), pied black and white (18.6 percent), black (17.9 percent) and pied red and white (14.7 percent). All animals had sloping rumps and most (81.8 percent) had small-sized humps. Most (94.8 percent) animals had pyramid-shaped humps located in the cervico-thoracic position. Most (91.5 percent) animals had upward–forward oriented and lyre-shaped horns. All the animals had flat faces and backs, and laterally oriented ears. Most (97.1 percent) animals had medium-sized dewlaps, medium-sized teats (93.6 percent) and medium-sized quarters (87.2 percent). The navel flap was absent in most (87.6 percent) animals. Thus, the Fipa cattle can be classified as a medium-sized strain with considerable variation in body size and morphological features within and between districts.

The Moroccan goat livestock is characterized by the existence of different phenotypes distributed among diverse geographic locations. The objective of this study was to analyse the morphometric traits that differentiate the Draa breed from the other local populations raised in areas close to its cradle zone. Eight morphometric measurements were taken on 287 goats in South-eastern and Southern Morocco. The variance analysis, fitting a model that included the random effect of animal and the fixed effects of population, gender and age of animal, was used. Mahalanobis distances were calculated between identified populations and an Unweighted Pairs Group Method Analysis tree was built. Draa goats had the highest height at withers (61.5 cm), heart girth (74.4 cm), body length (64.6 cm) and live body weight (27.2 kg). These morphometric traits varied significantly among populations as well as the age and the gender of animal. The most discriminating traits between the identified populations were the body length, the heart girth, the hair length, the horn length, the ear length and the live body weight. Draa animals had the largest genetic distances from the other populations and appeared more distinguished from them. This differentiation can contribute in defining the phenotypic standard of the breed and in orienting its genetic improvement programs in the future.

The study was aimed to identify, characterize and describe the phenotypic variation of indigenous goose populations in Bangladesh. The research was conducted at Sylhet Sadar Upazilla in Sylhet district and encompassed about 141 geese (74 brown type and 67 white type). Least Square Mean ± SE of body length, wing span, shank length, beak length and head length of mature indigenous goose were 73.47 ± 0.95, 134.53 ± 1.38, 9.27 ± 0.09, 8.88 ± 0.10 and 6.42 ± 0.02 cm, respectively. Males were significantly (p < 0.01) higher than their female counterparts for all morphometric traits but no significant differences (p > 0.05) were found between two types. The body weight of indigenous goose at day old, 2-week, 1-month, 2-month and 10-month of age were 95.45 ± 0.88, 148.59 ± 1.55, 407.34 ± 7.27 gm, 1.19 ± 0.03 kg and 3.65 ± 0.06 kg, respectively. Males were significantly (p < 0.01) heavier than females in all age groups except day old gosling but no significant difference (p > 0.05) were observed for body weights between two types of goose. Egg weight, egg length, egg width, incubation period, clutch size, number of eggs in a breeding season and age at first egg were 131.85 ± 1.70 gm, 7.40 ± 0.02 cm, 5.22 ± 0.02 cm, 30.30 ± 0.07 days, 7.42 ± 0.08, 20.52 ± 0.38 and 313.22 ± 3.03 days, respectively. The number of eggs in a breeding season of brown type were significantly (p < 0.05) higher than that of white type goose. This study provides a bench mark for the morphometric traits and performance of goose in Bangladesh.

The Vogan sheep (VS), a crossbreed between Djallonke sheep (DS) and sahelian sheep (SS), is a unique sheep breed in Togo. It is highly valued for its performances but its breeding is very localized in southeastern of Togo. The objective of this study was to update the breed's phenotypic characterization and to compare VS phenotypic features with those of parental populations (DS and SS). For this purpose, morphological data were collected in January 2013 from 206 animals in Vô, Kloto and Agou prefectures (Togo) and in May 2013 from 30 SS in Bobo-Dioulasso (Burkina Faso). Results showed that the coat colour was very variable. Horn shape was also variable but was generally prismatic and outward-oriented, present in all rams and fine or remains of them in ewes. Quantitative traits such as height at withers, body length, chest circumference, tail length, ear length, space between the horns and chest depth showed that VS traits are smaller than SS traits but are significantly superior when compared to DS traits. Most VS characters were influenced by geographic location (p < 0,05). This study confirmed the “intermediate” status of VS. The sustainable use of VS needs molecular characterization and a dissemination programme.

Indigenous cattle support approximately 26.1 percent of Ugandan families through provision of food and income in addition to the supply of socio-cultural wealth and security. Cattle keepers have developed and maintained variations of indigenous cattle phenotypes and genotypes suited to their agro-ecological zones through traditional management practices and socio-cultural aspects. The Ankole (Bos taurus indicus), East African shorthorn Zebu (Bos indicus) and their crossbred cattle constitute the main indigenous breeds, adding up to 93.3 percent of the Ugandan herd. With intensions to increase productivity, state policies encourage livestock farmers to upgrade local genotypes towards high yielding exotic dairy cattle. This if not appropriately planned is likely to result into loss of local genetic diversity, well endowed with resilience to local climatic conditions, endemic diseases and feed resource constraints. Here in, we review literature related to indigenous cattle in Uganda including how diverse landscapes, local management practices and socio-cultural aspects have enriched patterns of indigenous cattle variations. Then we highlight potential challenges of intensive management, increased selection for higher productivity and threats to genetic diversity of indigenous cattle populations. Since indigenous cattle vary with landscapes and socio-cultural values, have taken decades to establish, efforts to save them through genetic diversity studies, conservation and farmers sensitization should be undertaken immediately.

Backyard poultry is considered as a powerful tool for poverty alleviation. It is further promoted as a way of empowering women in communities where there is gender bias in poultry raising. The low-input systems involved are based on local breeds that are perfectly suited to their environment. However, socio-economic processes put local genetic resources under pressure, leading to the erosion of biodiversity. The present survey addresses this issue in the case of Kabylie, a mountainous coastal region of Algeria, through a survey conducted in 90 households raising poultry, a morpho-biometric description of 315 local chickens, and a performance evaluation of both growth and egg production in experimental semi-intensive conditions. The socio-economic profile of poultry smallholders in Kabylie reveals poor education and high diversification of agricultural assets and confirms gender bias in poultry keeping. The erosion of local genetic resources in chicken is found to be severe despite their cultural importance in Kabylie. From complementary surveys among experienced poultry keepers, the major original local type is postulated to consist of three varieties with black plumage (pure black, mottled and barred). The performance evaluation raised promising results, suggesting that exploiting the local breed could pursue some degree of improvement of low-input backyard systems. Finally, a strategy for a revival of the local breed through the support of the most involved smallholders is outlined in accordance with the information collected in the survey.

A study of the genetic diversity of Sardinian sheep identified a small population of Pecora Nera di Arbus sheep. This population is composed of about 1000 ewes located in the southwest of Sardinia (Medio-Campidano district), mainly in the area surrounding the village of Arbus. The main features of this breed are black fleece, small size, small or absent auricles and a high frequency of horns in both sexes. These ancestral traits suggest that the population escaped the selection process, that was mainly oriented toward milk yield and the white colour of the fleece, for which the predominant white strain of Sardinian sheep was established. Currently, a programme of promoting this new breed is ongoing. It is mainly based on the production of natural black wool for apparel without chemical dyes.

The objective of the study was to determine the phenotypic variation among four Bhutan indigenous chickens (BIC) namely Seim (SM), Phulom (PL), Yuebjha Narp (YN) and Khuilay (KL). A total of 120 chickens (KL, 30; YN, 30; PL, 30; SM, 30) were included for the present study. Based on descriptive statistic analysis, the results illustrate that there are three types of comb and single type predominant. The Bhutanese chickens do not have feather on the shank and the head type is plain. The common colours of earlobe in four indigenous birds are white and red. White skin and shank colour rank high among BIC groups; however, in SM the yellowish skin colour is observed high. The predominant feather colour of four indigenous chickens is pure black in YN (48.28 percent), white in KL (30.00 percent), reddish brown in SM (33.33 percent) and PL (23.33 percent). In addition, breast, back and neck feather followed the similar pattern of colour. Among BIC populations, KL and YN strains present the greatest and lowest plumage colour diversity, respectively. For example, eight different colours of breast feather are surveyed in KL and PL birds. Therefore, considering the variation in feather colourings, KL and PL seems to have more diversity in morphology but, it requires further studies. On the other hand, YN appears to have less diversity requiring for appropriate development of conservation strategies in Bhutan. Moreover, the large variations present the possibility of making improvement among BIC.

The staggering population of 40 thousand from an imposing number of 132 thousand of 1977 in the Himalayan states of India has evoked a concern for adopting measures for conservation and irnprovements. The dwindling population is triggering the highlander's economy from bad to worse. Rearing in the precinct of high hills in very small population units conjoint with the absence of any scientific breeding policy has resulted in visible diversification of physical conformation (colour, shape, size of body and horn characteristics) and deterioration in productive proficiency of the yaks of India.

The Black Maltese is a nearly-extinct light breed of non-sitting, egg-type chicken, present in the Maltese Islands. Formerly widely reared under backyard conditions for its abundant, white eggs, it has now been entirely replaced by intensely-reared synthetic strains of poultry. This breed is also absent from the remaining backyard flocks in Malta, having been replaced by Rhode Island Red commercial strains. The Black Maltese survives in dwindling numbers as a curiosity and show-bird for poultry shows. The current spatial distribution and breed population size were determined, and breed standard was established. Suggestions on safeguarding this breed were also discussed.

Argentina's annual camelid fibre production is estimated at 60 000 kg for llama (Lama glama), somewhat more than 2 000 kg for guanaco (Lama guanicoe) and about 845 kg for vicuña (Vicugna vicugna). The potential for increasing these amounts is huge considering that barely 30 percent of llamas are shorn and considering the size of the wild camelid population in the country. A compilation of published and unpublished work confirms that almost 50 percent of the llamas are single-coated, about 40 percent have white fleeces and that average fibre diameter is about 22 µm in the main llama production area. In general, there is a wide variation in fleece weights and fibre quality between and within herds. However, a llama fleece classing and pricing system is not yet in place to motivate implementation of breeding programmes. Guanaco and vicuña fleeces are double-coated but the fine undercoat represents more than 80 percent of the fleece weight. The proportion of down fibre remaining after mechanical dehairing is only 50 percent in guanacos and 70 percent in vicuñas. The guanaco undercoat fibre diameter is about 16 µm and vicuña fibre diameter is typically between 13 and 14 µm. Both fibres are relatively short. Research is needed to establish optimum shearing season and shearing frequency that results in fibre quality demanded for handcraft and industry in each of the three species.

The present work is intended to describe the variability of fibre colours in the population of alpacas from the region of Huancavelica, Peru. The population structure, the incidence of defects and the quality of the fibre, were also analysed. A total of 2341 animals from 22 flocks from seven communities with colour alpacas were characterised. The quality of fibre was analysed using a small subsample (121 alpacas). 10% of the animals were Huarizos and about 20% of stained colour. 96% of the animals of solid colour were from Huacaya breed and only 4% of Suri breed. Sixty six percent of the alpacas were of white colour. The cream and coffee colours were well represented, not however the black and grey. For the Suri breed, the conservation problem goes beyond its colouration, the breed itself being at risk. The population structure and the presence of defects seem to indicate less attention in the handling of the colour alpacas than in the white alpacas. Also the quality of the fibre of the coloured animals was less than that of the white alpacas, decreasing as the dark tone of the fibre increased.

Typical features, breeding objectives and morphological as well as biometrical characters of Begait sheep breed were studied in two districts (Setit Humera and Kafta Humera) of Ethiopia. Semi-structured questionnaires, recording body weight, linear body measurements and field observations were employed. Begait sheep breed is described as long and thin tailed (up to 50-cm long), with muscular body, short and smooth hair and polled for both male and female sexes. As reported by the respondents’ growth rate (0.21), tail length (0.20), appearance/conformation (0.19) and coat colour (0.18) were the most important traits in selecting breeding rams. For breeding ewes’ body size (0.27), age at first service (0.15), growth rate (0.14) and coat colour and tail (0.13) were their first, second, third and fourth traits, respectively. Sites and age had significant (P < 0.01) effect on body weight and most linear body measurements. Relatively, Kafta Humera had lower values in body weight and most of the linear body measurements than Setit Humera. The overall mean body weight and body length of female Begait sheep were 31.4 ± 0.4 kg and 62.5 ± 0.5 cm, respectively. The corresponding values for male Begait sheep were 34.5 ± 0.5 kg and 66.1 ± 0.5 cm, respectively. The existing traditional herding, breeding practices and trait preferences are the key breeding components that need improvement at smallholder farmers’ in Ethiopia.

There is an increasing concern about losing genetic diversity in farm animals, and poultry genetic resources are considered to be one of the most endangered (Crawford, 1990). A large number of local dual-purpose breeds used at the beginning of the last century have been replaced with highly specialised lines. Market orientated intensive livestock breeding programs tend to concentrate on just a limited number of breeds, and the proportion of low-input, low-output breeds used in agricultural production in developed countries has been decreased almost to zero. Decreasing numbers of breeds results in reduced genetic variability, and limits the flexibility of future breeding programs. On the other hand, an increase in income in these countries leads to a rise in demands for specialised food, diversification in the product supply, and changes in preferences of production conditions.

Pedigrees of a reference population of 1 659 North American Norwegian Fjord horses were traced to founders and analysed for coefficients of inbreeding and genetic variability. Effective population size was 207.8 and there were 641 total founders. Pedigree completeness was close to 100 percent for 6 generations, with 9.8 average complete generation equivalents. The average inbreeding coefficient was 3.2 percent for the entire pedigree and 1.6 percent for pedigrees traced back five generations. Average inbreeding coefficients by year of birth increased until 1983, before decreasing and then stabilizing through 2009. Effective number of founders, ancestors and genomes were 96, 30.0 and 12.7, respectively. Low effective number of founders and ancestors indicate that genetic diversity has been lost in the development of the breed in North America. However, registry-enforced breeding strategies have contributed to lower inbreeding coefficients in the current generation.

Hassawi cattle breed is a mix of Bos indicus and Bos taurus. The cattle are raised in the Eastern province of the country by farming families in mixed farming system. The breed numbers are declining very fast, from 10 449 head in 1986 to an estimated maximum of 4 500 head at present.

The decrease is mainly due to replacement by exotic breeds, the indiscriminate crossing with these exotics, particularly in view of the scarcity of the Hassawi bulls for mating. Animals are small in size, mature body weight 210-270 kg for bulls and 150-200 kg for cows, quite uniform in colour (light red) and body conformation have conspicuously reduced dewlap and umbilical folds and relatively large hump. Animals are heat tolerant, sustain high feed intake under ambient temperature, resistant to many diseases prevailing in the region and cows have good mothering ability. Productivity of the breed in terms of meat and milk is low when compared to that of exotics in high input production environments, but reproduction performance excels that of temperate breeds and zebu cattle.

Efforts should be made to stop the decline in the breed numbers and to conserve the breed as an asset for production under harsh environment.

The study examines phenotypic characterization of Central Highland and Woyto-Guji goat breeds at Meta Robi and Konso districts of Ethiopia. Purposive and random sampling techniques were employed to select sample villages and respondent. For administration of semi-structured questionnaire and phenotypic characterization, a total of 240 households and 601 adult animals, respectively, were selected. The average goat flock size (31.25 ± 22.46) owned per household of Konso was significantly (P < 0.01) higher than Meta Robi (12.73 ± 8). In Konso, natural pasture was the most frequently mentioned feed source during wet season, while hay was the most important feed source during dry season. On the other hand, in Meta Robi, natural pasture was the most frequently mentioned feed source during wet and dry seasons. Coat colour type, horn shape, ear orientation, wattle and beard were found to differ highly significantly (P < 0.001) among the two goat breeds. Goat breed had a significant effect (P < 0.001) on body weight and other body measurements except pelvic width (P > 0.05). The least-square means of body weight, body length, height at wither, chest girth, chest width, ramp length, horn length, ear length and pelvic width of Central Highland female goats were 29.5 ± 0.2 kg, 62.2 ± 0.2 cm, 67.5 ± 0.2 cm, 72.9 ± 0.2 cm, 13.4 ± 0.1 cm, 19.7 ± 0.1 cm, 12.8 ± 0.2 cm, 14.6 ± 0.1 cm and 13.5 ± 0.1 cm, respectively. The corresponding values for Woyto-Guji female goats were 24.8 ± 0.3 kg, 57.4 ± 0.2 cm, 61.9 ± 0.2 cm, 68.3 ± 0.2 cm, 12.1 ± 0.1 cm, 17.3 ± 0.1 cm, 10 ± 0.2 cm, 13 ± 0.1 cm and 13.4 ± 0.1 cm, respectively. The observed variations in production system and morphological traits among the sample populations coupled with their adaptive traits would indeed justify the need for designing breed improvement programme for both breeds.

After the war in Kosovo, the Food and Agriculture Organization and the World Bank implemented an Emergency Farm Restocking Project, by allocating Simmental, Brown Swiss and Tyrol Grey heifers, 4–7 months pregnant, to farmers at the rate of one per farm. Data was monitored over a period of 14–16 months and the results showed that Brown Swiss had the highest milk production, while Tyrol Grey did worst. However, Tyrol Grey had the shortest service period and also changed the body condition score postpartum less than the other two breeds, making it best fitted of the three, to the extensive environment in Kosovo. Breeds were compared by growth rate, but this comparison was deemed highly inadequate as breeds with a high growth rate normally reach maturity at a high weight, and so need intensive feeding. Considering the extensive production environment in Kosovo, our results suggest that dairy cattle production should be based on a smaller breed, well adapted to the diet offered

Se describen las actividades de conservación y caracterización del bovino criollo peruano en el Instituto Nacional de Investigación y extensión Agraria (INIEA), las mismas que se han desarrollado con la activa interacción con las comunidades rurales de las regiones peruanas de Ancash, Apurímac, Ayacucho, Junín y Puno, dedicadas a la crianza de ganado criollo; en las comunidades también se llevaron a cabo trabajo de campo y charlas participativas sobre la conservación de sus morfotipos locales. Las actividades desarrolladas incluyen la caracterización morfológica y molecular empleando microsatélites y RFLP para detectar genotipos de proteínas lácteas (variantes de kappa caseínas y beta lactoglobulinas). Esta información será de utilidad para los programas de mejoramiento del bovino criollo peruano en las comunidades rurales.
