Genetic diversity and population structure of six ethiopian cattle breeds from different geographical regions using high density single nucleotide polymorphisms. The cattle which are slaughtered on ceremonial occasions are also of impor-tance in the religious and tribal customs. 2. Utility: The Abigar cattle are used mainly for milk; they are used for their beef during traditional ceremonies; occasional taking of blood from young bulls for human food was common in earlier times (Rege 1999). Cattle production in Ethio-pia is an integral part of almost all farming systems in the Over 1000 breeds of cattle are recognized worldwide, some of which adapted to the local climate, others which were bred by humans for specialized uses.. Cattle breeds fall into two main types, which are regarded as either two closely related species, or two subspecies of one species. So far, the Ministry has imported the same cattle breeds from the Netherlands and South Africa. The result of this study was comparable with the finding of [13] on local Ethiopian cattle breeds that showed mean forequarter of Boran at 4 - 6 years similar with Barka (34.28 kg), and Harar at 7 - 9 years with Raya (29.78 kg) breeds.

Characterization of six cattle breeds in North Ethiopia Table 5. most Ethiopian cattle breeds are under threat from un-controlled breeding practices and are at high risk of becoming genetically homogenous [1]. Trypanotolerance and phenotypic characteristics of four Ethiopian cattle breeds. Among Ethiopian cattle populations, the proportion of SNPs with minor allele frequencies (MAFs) ≥0.05 ranged from 81.63% in Borana to 85.30% in Ambo, with a mean of 83.96% across all populations. The Raya cattle have red and black coat colours. Download PDF Download. Keywords: Indigenous Breeds, Cattle, Productivity, Economic, Cultural Values, Nigeria. The majority of Ethiopian cattle (e.g., Boran and Horro) are low producers of milk with high individual variability (Yohannes et al., 2002) which is attributed to natural selection to the tropical environment and management. Livestock population 2.1.1. 32 recognized indigenous cattle breeds (DAGRIS (the Domestic Animal Genetic Resources System) 2007) and has a wealth of undocumented indigenous knowledge on cattle … Volume 234, April 2020, 103979. Genetic diversity and population structure of six ethiopian cattle breeds from different geographical regions using high density single nucleotide polymorphisms. While 99.4 percent of the total cattle in the country are local breeds, the proportion of hybrid and exotic breeds is In Ethiopia some breeds live in infected areas and could possess trypanotolerance. All the three exotic breeds produced more than double the number produced by the indigenous chickens. Even though all breeds have contributed to current diversity levels, the Afar and Abergelle breeds only contributed 51% and 62% to the MVT and MVO core sets, respectively, while the Raya breed contributed only 6% and 1.5% to the MVT and MVO core set diversities, respectively. Eco-system and agro-ecological distribution of cattle breeds/types..... 98 Table 25. The Abergelle and Irob cattle breeds of North Ethiopia: description and on-farm characterisation - Volume 36 - M.

The hindquarter weight of Arsi breed in age categories from 4 - 6 years was relatively lower than their counter part Boran and Harar breeds. Classification and population size of Ethiopian cattle breed..... 97 Table 24. Livestock Science. The Abergelle is one of the smallest cattle breeds in the region and lives on plains and in river valleys at an altitude ranging between 1,300 – 1,550 meters (4,265 – 4,921 feet). 2003). Even though all breeds have contributed to current diversity levels, the Afar and Abergelle breeds only contributed 51% and 62% to the MVT and MVO core sets, respectively, while the Raya breed contributed only 6% and 1.5% to the MVT and MVO core set diversities, respectively. Therefore, most of the milking cows are indigenous animals with low production performance with an average age of first calving being 53 months while 25 months for average calving intervals of 25 months. Diss. Variables and criteria for the estimation of the extinction probability of African cattle breeds. In addition* low nutritional stanc’ard and genetic capacity both contribute to low feed conversion rates. Adequate feeding is necessary to utilize both the potential of the animal health programmes and the genetic potential of the animalsindigenous as well as genetically improved. Livestock … Ethiopian cattle breeds Tesfaye Amene Dadi Department of Animal Science, College of Agriculture and Natural Resources, Mizan-Tepi University, P.O. sistant local cattle breeds can continue to play the extremely im portant role in the economies of these areas that they have there at present. Studies on Borana and Horro cattle revealed the suitability of indigenous cattle for crossbreeding for dairy production. eastern margin of the north Ethiopian highlands: Use: Draught, meat, milk (in that order) Traits; Coat: red, black: Horn status: long: Cattle; Bos primigenius; The long-horned Raya cattle are a breed of cattle common in the Tigray Region of Ethiopia. The heaviest egg weight was obtained from Rhode Island Red and White Leghorn hens, which is a reflection of their larger body size (Leeson and Summers 1997). Box 260, Mizan-Tepi, Ethiopia. Trypanotolerant breeds, however, can survive, produce and reproduce even under disease pressure. Characterization of Animal Genetic Resources 11 3. LIVESTOCK PRODUCTION 2.1. While in the farming system, feed requirements are got from native pasture with supplement from crop residues and stub grazing. Trypanosomosis is the single most important livestock disease in sub-Saharan Africa. As a representative of taurine breeds, Hanwoo cattle (n = 40) were also included in the study for reference. E-mail: tesfuam@gmail.com. 2 Ethiopia has an area of about l,221.9oo km , fiftythree per cent of which are permanent pasture, eleven percent cultivated land and eighteen percent barren desert 'or swamps. Key words: Age at First Calving, Milk Yield, Birth Weight, Calving Interval, Lactation Length, Number of service per conception 5 6 1. Keywords: Crossbreeding, heterosis, performance, milk yield, birth weight. INTRODUCTION Cattle command a prominent position in our meat supply and livestock industry. The general conclusion is that the difference among Bos indicus breeds in Ethiopia for crossbreeding seems to be insignificant (Kiwuwa et al., 1983; Beyene, 1992). The rest are rivers, lakes or forests. Study Area 13 3.2. The Guraghe highland and Arsi breeds fall under Zebu breed group, the Sheko come from Humpless Shorthorn, the Abigar from the Sanga group and the Horro from Zenga group. MATERIALS AND METHODS 13 3.1. Milk yield could be increased through within and between breed selection and crossbreeding with cattle from improved dairy breeds. cattle owners are beginning to understand the economic value, based on productivity, to be derived from the ownership of a herd. Classification, estimated population size, and locality of sheep breeds/types..... 99 Table 26. Among Ethiopian cattle populations, the proportion of SNPs with minor allele frequencies (MAFs) ≥0.05 ranged from 81.63% in Borana to 85.30% in Ambo, with a mean of 83.96% across all populations. Volume 234, April 2020, 103979. Related cattle breeds in the Sudan are the Nuer, Aliab Dinka, Aweil Dinka and Shilluk cattle (Rege 1999).
