Characteristics of lactation performance, based on AM milk offtake and conformation, of Ankole cattle were studied during one year in 37 herds with 606 recorded cows in Mbarara district in southwestern Uganda. Recording of AM milk offtake was undertaken in eight areas of Mbarara district which represent different production systems and vegetation types.

The 467 cows with complete lactation cows yielded, on average, a total AM offtake of 252 and 325 kg over first and second or higher lactations, respectively. These offtakes were higher than other African indigenous populations in pastoral systems. Mean body weight was 292 and 341 kg for first and second or higher parities, respectively. Average body measurements for all parities were 161 cm for heart girth, 129 cm for height at withers and 193 cm for body length.

The daily AM milk offtake varied from 1.1 kg in the Ruhengere area characterized by thorny Acacia thickets to 1.9 kg in the bush-cleared Kanyanya area with improved pastures. Although the Ankole cows performed best on the improved pastures, their future may relatively be more favourable in the original non-cleared bush areas because of the gradually increasing competition from exotic dairy breeds and their crosses.

The American Milking Devon Association was established in 1978 to record and preserve a unique type of cattle originally developed in the United States in the 17th century from imported English and contemporary American stocks. Phenotypically, it exhibits a spectrum of red colour, with light-coloured curved horns and medium body size. The breed is one of the few remaining triple-purpose breeds in the United States, and has been selected by breeders since colonial times for excellent temperament and powerful draught ability, along with desirable dairy and beef characteristics. It is well adapted to low-input management schemes and harsh environments. The American Milking Devon is currently found on the ‘critical’ list of the American Livestock Breeds Conservancy, indicating that there are fewer than 200 new registrations annually. Since the inception of the American Milking Devon Association, a small group of dedicated breeders has done much to preserve these cattle. However, new management tools are now being introduced to assist breeders and allow conservation of genetic diversity while retaining the original breed traits in terms of size, colour, beef and dairy production, and character and working ability.

This study was undertaken in order to characterize the Ponwar breed and to establish its present status so that suitable breeding strategies and conservation models could be suggested for the overall improvement of the breed.

The Ponwar is a draught cattle breed and is native to the Pilibhit District of Uttar Pradesh. The breeding tract lies between latitude 28°4' and 28°8' North and between longitude 79°0' and 80°4' East. The coat colour of these animals is brown or black with white patches in varying proportions. The tail switch is white in black animals and black in those having a greater proportion of white patches. The body is small, compact and non-fleshy, the face is small and narrow and the ears are small. The horns are small to medium and curve inward with pointed tips. The hump is small in females and developed in males. The tail is long and reaches to below the hock. Cows have small udders and teats. The animals of this breed possess an aggressive temperament.

The milk production of the Ponwar cows is low, i.e. about 0.5 to 2.5 kg per day for a lactation period of 8 to 10 (average 8.9±0.1) months. Lactation milk yield averaged 462.5±12.1 kg. The age at first calving ranged from 40 to 60 months and the inter-calving period averaged 12.6±0.1 months. The service period in Ponwar cattle varied from 60 to 100 days. The cows remained dry for average of 110.0±2.6 days. Bullocks of this breed can transport an 800 to 1 000 kg load up to 10 kilometres easily. They can plough 0.4 hectares of land in a day working for 6 to 8 hours. Body length, height at wither and heart girth in adult cows averaged 97.1±0.5, 109.0±0.4 and 140.6±0.5 cm, respectively. The animals recorded in the different villages had similar average body measurements corresponding to their category. The survey revealed that about 21% of total cattle population was of Ponwar breed in Puranpur Tehsil. The approximate Ponwar population in the entire breeding tract was estimated as 10 667.

The genetic relationship among Nigeria's breeds of sheep and their crosses was studied using microsatellite DNA polymorphisms. DNA samples extracted from four Nigeria's breeds of sheep (West African Dwarf, the Balami, Uda and Yankassa) and their crosses were analysed using 30 Bovine microsatellite markers for diversity studies. Twenty of the markers were amplified by the sheep genome. Nineteen of the loci were polymorphic and were used to calculate genetic distances (Ds) between the breeds based on allele frequencies of the microsatellite. The phylogenetic relationships between the breeds were similarly estimated.

With the total number of loci studied, 285 alleles were generated and a high degree of heterozygosity was recorded (0.57 to 0.72). A relatively high degree of reliability could be placed on the tree topology with the relationship between breeds displaying a closer relationship between the Yankassa and Uda (Ds 0.356). The genetic distance was 0.432, 0.534 and 0.665 between the West African Dwarf (WAD) and the Yankassa, Uda and Balami respectively which also indicated a closer relationship between the Yankassa and the WAD compared to the essentially Northern breeds (Uda and Balami). This further confirms the evolutionary divergence of the breeds which makes them distinct entities.

The data suggests that microsatellite DNA markers are very useful tools for studying the genetic relationships among these sheep breeds. The highly polymorphic alleles could similarly be exploited in breed improvement and development.

En este trabajo se describen las iniciativas de conservación de la oveja de raza Xalda de Asturias. Es una oveja de pequeño tamaño, y de color predominantemente negro que presenta gran similitud morfológica con otras razas ovinas del Arco Atlántico Europeo como la Ouessant o la Morite. En 1992 se funda la asociación de criadores de la raza (ACOXA) y comienza el funcionamiento del Libro Genealógico. Durante la última década la actividad de ACOXA ha estado centrada en la recuperación de individuos aislados fomentando su cría en raza pura. Se ha realizado un análisis de la información genealógica contenida en el Libro Genealógico detectándose el excesivo uso de algunos reproductores que puede provocar una pérdida de variabilidad genética en la población. A partir de estos resultados parece necesario llevar a cabo estrategias de apareamientos que aseguren el mantenimiento del patrimonio genético de la raza.

El presente trabajo tuvo como objetivo caracterizar fenotípicamente un rebaño de cabras azules, pertenecientes a la granja Carnaúba, municipio de Taperoá, Estado de Paraiba, Brasil, con el propósito de contribuir a la homologación del patrón racial en el Ministerio de Agricultura. Fueron evaluadas 62 hembras azules con edades a partir de dos años y peso medio de 40,3 kg, tomándose las siguientes medidas morfométricas: longitud corporal (71,5±5,6 cm), altura a la cruz (59,0±4,3 cm), perímetro torácico (76,9±4,8 cm), longitud de las orejas (12,6 cm), formato de los cuernos (bien implantados, simétricos, dirigidos hacia arriba, hacia detrás y hacia afuera, con pequeñas curvaturas hacia el frente en las extremidades y color ceniza oscuro). Los animales presentaron tres patrones distintos de capa: ceniza claro, ceniza azulado y ceniza azulado muy oscuro. Este estudio contribuirá al fortalecimiento de los trabajos de conservación de esta raza, que se encuentra en estado crítico debido a cruzamientos absorbentes e indiscriminados con otras razas exóticas.

This study was carried out to investigate the fertility, milk production and body weight of ewes and the survival and growth characteristics of lambs of the indigenous Imroz and Kivircik sheep breeds. The Imroz and Kivircik sheep breeds are included among the genetic resources in the project for the conservation of the indigenous breeds in Turkey.

Conception rates for Imroz and Kivircik ewes were 57.6% and 81.7% respectively, litter sizes were 1.2 and 1.2 respectively, milk yields were 89 kg and 62 kg respectively and average live weights (2–7 years of age) were 43 kg and 55 kg, respectively. Imroz and Kivircik lambs had survival rates at weaning (90th day) of 98% and 96%, birth weights of 3.3 kg and 4.1 kg and weaning weights of 19.8 kg and 28.0 kg, respectively.

The results showed that the Kivircik sheep were heavier and the lambs had a better growth rate until weaning than the Imroz breed. However, the milk production of the Imroz ewes was higher than that of Kivircik. The lambs of both breeds had a satisfactory survival and growth rates until weaning and these results might be regarded as a desired adaptation of the Imroz and Kivircik lambs to the environmental conditions of the Marmara Region.

Jalauni sheep are found in the Bundelkhand region of Uttar Pradesh and Madhya Pradesh states in India. About 37% of the geographical area of this region is under cultivation and about 86% of the population, mostly directly or indirectly dependent on agriculture, live in villages. Forests, cultivable waste and barren land occupy more than 50% of the area, permanent pasture and other grazing lands about 9% and miscellaneous tree crops and grasses about 0.7%. The livestock census figures of 1977 and 1997 indicate an annual declining trend of 0.04 % in the sheep population in Uttar Pradesh and Madhya Pradesh states. Characterization and evaluation of Jalauni sheep under field conditions were undertaken to establish the norms, morphological characteristics and performance parameters of this breed. A total of 78 households were visited in 29 villages in five districts. Information on feeding, breeding and management practices, utility patterns etc. and production and reproductive performance was collected through personal observations and interaction with the farmers. Body weight and/or body measurements were recorded for 374 animals. Average adult body weights of male and female Jalauni sheep were 35.5±2.1 and 27.2±0.7 kg respectively. Age at first lambing was 1.5 to 2 years and lambing interval one year. A ewe, on an average, delivers 7–9 lambs in her lifetime.

The breeding tract of Spiti horses is located in the Kaja subdivision of the Lahul and Spiti district and the Yanthang area of the Kinnaur district of Himachal Pradesh in India. The horses in this area are smaller in height and called Spiti ponies. They are reared as pack animals at high altitude. Their body is well developed with fairly strong bones. The mane is long and has hairs of 25 to 40 cm in length. The body is solid, displaying and alert attitude, the face is convex, the ears are erect and the eyes are black. The tail is medium in length and straight. The horses are docile in temperament. The body colours are grey, brown, black and piebald. On an average, these horses stand 129 cm height, have a body length of 100 cm, a heart girth of 148 cm, an ear length of 15 cm and a face length of 50 cm. Animals are reared on grazing (alpine pasture) from May to November and stall fed from December to April. The breeding season is from February to July. The average age at first fertile service, age at first foaling, gestation period, service period and foaling interval were estimated as 1 054, 1 297, 333, 63 and 516 days, respectively under intensive management at Kamand farm. It has also been ascertained from various sources that their number is declining rapidly, however breed population statistics are not available. There is, therefore, an urgent need to conserve this breed.

Indigenous Tswana pigs are mostly found in Southern Botswana. There is concern that the breed may become extinct due to the low usage of the breed and the lack of implementation of a comprehensive conservation strategy. The objectives of this study were to identify places where indigenous Tswana pigs are kept in Gaborone Agricultural Region and document the numbers, distribution, management and utilisation of these pigs. A formal questionnaire was administered to all indigenous pig farmers who could be identified. The data was analysed using procedure frequency in Statistical System Analysis. A total of 51 indigenous pig farmers were interviewed, of these 71%, 16% and 14% were in Southeast, Kgatleng and Kweneng districts respectively. Only one farmer kept crossbreeds with the majority keeping pure indigenous Tswana. A total of 124 sows, 23 boars, 32 castrates and 211 piglets were counted in this region. All the pigs were kept under the communal system. None of the farmers surveyed kept records and they exhibited limited knowledge of pig farming and improved management. Pigs were kept for home consumption with very few sold, given out as gifts or loaned out. Pig fat was used as a by-product to make soap and a lubricant in traditional leather rope making. The farmers’ perception of indigenous pigs is good; they claim that the pigs posses traits of economic importance such as high heat and drought tolerance, which are of great significance in the harsh climatic conditions of Botswana. There is a need to undertake conservation efforts for this breed given that it survives and reproduces under harsh climatic conditions and sub-standard management. More research and further action is required to increase the production of this breed.
