Phenotypic variations of indigenous sheep breed ecotypes of Ethiopia: A review

Karakachan sheep represents an endangered, indigenous sheep breed from Balkan Peninsula. There is relatively little information about the characteristics of this sheep breed in the veterinary scientific literature. The aim of this research was an examination of certain metabolic profile parameters of the Karakachan sheep blood serum, and variability of their concentrations in comparison to age and some other indigenous sheep breeds from Balkans. Examination was conducted on 14 clinically healthy sheep divided in two age groups. Blood samples were collected by puncture of v. jugularis and blood serum was separated after spontaneous coagulation. The concentrations of total protein, albumin, calcium, inorganic phosphorus, aspartate amino transferase (AST) and ?- glutamyl transferase (GGT) were determined. In relation to age of Karakachan sheep, statistically significant difference between the calculated mean values of examined parameters was not observed. A statistically significant difference was found between the mean concentrations of the studied parameters in Karakachan sheep and other breeds in total protein (Tsigai, Dubrovnik and Dalmatian sheep), albumin (Dalmatian), calcium and inorganic phosphorus (Tsigai, Dubrovnik) and AST's (Dalmatian, Karakachan sheep from Bulgaria).

The objective of this review paper was to review dorper sheep cross breeding with indigenous sheep breed in Ethiopia. The paper reviewed and discussed the history of dorper breed introduction, research and development efforts in crossbreeding and their performance under on-station and on-farm management. Formal survey on farmers perception on Dorper cross sheep indicated that the crossbred dorper sheep have non selective feed behavior and excellent in meat production under farmer`s management. On other study showed that dorper sheep was not meet farmer interest in breeding sheep aspect because of black coat color. The performance of indigenous sheep and their crosses with Dorper varied as per the location, management, farming conditions and percentage of exotic blood level inheritance. Different research output by team of researchers on farm and on station performance evaluation of dorper indicated that crossbreds often outperformed their local contemporaries. Under on farm condition, body weight at different ages was significantly higher in 50% Dorper crosses as compared to their 25% and75% counter parts.On station birth weight of Dorper (3.39 3.8 kg) better than crossbreed (3.0 3.24 ± 0.04 kg) and local sheep (2.36 2.77 kg), respectively.While the mean weaning weight (14 16 kg) and yearling weight (26.95 32.43 ± 0.46 kg) of 50% Dorper crossbreed was better than indigenous sheep breeds. However, crossbred ewes and local sheep breeds did not differ in litter size. Dorper crosses with Afar under on station is not economically important due to lower weight in all aspects. Crossbreeding programs of dorper with indigenous sheep require strong research and development support from public service and non-governmental institutions for sustainable design, optimization, and implementation in clearly defined production environments.

Abstract. The aim of this study was to analyze tendencies in the population of Patch Faced Maritza sheep breed and estimation of sustainability of the breeding program for this breed by analyzing continuity of farmer`s breeding activity. Patch Faced Maritza sheep breed is a local Bulgarian sheep breed typical for lowland regions of South Bulgaria and could be successfully used as local genetic resource in productive strategies for milk and meat production. Data about breeders and population structure of the breed during 27 years (1991-2017) were provided by the breeding association of Maritza sheep breed. The changes in the population structure during the 2005-2017 were tracking. The number of breeders included in the breeding program was increased from 10 to 88 herds. This positive trend in the population and increased farmer`s interest to participate in the breeding program were due to government programs for supporting sheep farming and preserve many indigenous sheep breeds that are part of agricultural heritage. The increased number of herds included in the breeding program led up to enlarge active population in three main reproductive categories: ewes, rams and breeding lambs. Comparatively small number of ewes, rams and breeding lambs which in 2005 were respectively 375, 13 and 180 run to 7678, 493 and 1868 in 2017. This enlarge of active population was achieved by three ways: joining farmers which kept Patch Faced Maritza sheep but not participating in official breeding program of the breed, increasing the breeding lambs for replacement rate and limited upgrade crossing. On the based breeding activity contracts with farmers it was estimated continuity of breeding activity in two categories of breeders: finished breeding activity with the breed and continuing with active breeding activity with the breed. The causes for discontinuing of active farmers breeding work were analysed. A total number of farmers which finished breeding activity was 54 for 27 years. Averaged continuity of farmer`s breeding activity was 4.26 years. The analysis of this information find out five reasons for discontinuing farmers breeding activity: disinterest, death, old age, switching to another business, and changing the breed. From the listed reasons the most important are switching to another business 23 farmers and disinterest for active breeding work 17 farmers. The most important fact results nowadays is the fact that Patch Faced Maritza sheep is occurred already in 11 regions in Bulgaria, although 74.11% of the population is situated in two regions Plovdiv and Pazardzhik.

The present study was conducted to determine the slaughter and carcass traits of male lambs of the Akkaraman (A), Morkaraman (M), Awassi (IW), Karayaka (KR), Kıvırcık (KV) and Middle Anatolian Merino (MAM) sheep breeds. Fattening of all lambs started when they were at 90 days at weaning and finished when they reached bodyweight of 40 kg. The cold dressing percentage of lambs of A, M, and IW breeds were significantly lower than those of KV, KR and MAM. Fat depth and muscle area were significantly greater in KV and MAM lambs than those of the other breeds. There were significant differences among breeds in shoulder, leg and lean weights. Weights of back loin in KV and MAM lambs were significantly greater than those of the other breeds. The highest values for carcass fleshiness were obtained in MAM and IW lambs, but they had a significantly lower carcass fatness score. There were significant differences among the breeds in carcass compactness and leg conformation. The results of the present study indicated that A and MAM breeds could be recommended for desirable carcass characteristics.Keywords: Carcass cuts, indigenous sheep breed, intensive lamb finishing, meat formation, SEUROP classification

True Population

AbstractThe assignment of an individual to the true population of origin is one of the most important applications of genomic data for practical use in animal breeding. The aim of this study was to develop a statistical method and then, to identify the minimum number of informative SNP markers from high-throughput genotyping data that would be able to trace the true breed of unknown samples in indigenous sheep breeds. The total numbers of 217 animals were genotyped using Illumina OvineSNP50K BeadChip in Zel, Lori-Bakhtiari, Afshari, Moqani, Qezel and a wild-type Iranian sheep breed. After SNP quality check, the principal component analysis (PCA) was used to determine how the animals allocated to the groups using all genotyped markers. The results revealed that the first principal component (PC1) separated out the two domestic and wild sheep breeds, and all domestic breeds were separated from each other for PC2. The genetic distance between different breeds was calculated using FST and Reynold methods and the results showed that the breeds were well differentiated. A statistical method was developed using the stepwise discriminant analysis (SDA) and the linear discriminant analysis (LDA) to reduce the number of SNPs for discriminating 6 different Iranian sheep populations and K-fold cross-validation technique was employed to evaluate the potential of a selected subset of SNPs in assignment success rate. The procedure selected reduced pools of markers into 201 SNPs that were able to exactly discriminate all sheep populations with 100% accuracy. Moreover, a discriminate analysis of principal components (DAPC) developed using 201 linearly independent SNPs revealed that these markers were able to assign all individuals into true breed. Finally, these 201 identified SNPs were successfully used in an independent out-group breed consisting 96 samples of Baluchi sheep breed and the results indicated that these markers are able to correctly allocate all unknown samples to true population of origin. In general, the results of this study indicated that the combined use of the SDA and LDA techniques represents an efficient strategy for selecting a reduced pool of highly discriminant markers.

Economic Support

European farmers of indigenous local breeds have benefited from European Union economic support in the past and it is forecast to continue being supported in the future. However, it is in the public debate that economic support cannot last forever. Then, for the long-run maintenance of indigenous local breeds to be possible, the derived meat products from these breeds should be demanded by consumers or at least by a group of local consumers. This is the aim of this paper, to study consumers’ demand for indigenous local meat products. In particular, to assess how much consumers are willing to pay for a Spanish lamb meat from an indigenous sheep breed (“Ojinegra de Teruel”). To do that, a non-hypothetical experimental auction with local consumers (those living in a medium-size town around 150 km from the producing area of this meat) was used. Results indicated that consumers were willing to pay, on average, €0.45 (15% of the market price) more for the lamb meat with the “Ojinegra de Teruel” breed claim than for the one without breed indication (as it is now sold in the market). Then, local consumers clearly accept the differentiated meat through the indigenous breed indication. Then, producers in the area could have more opportunities to sell in the local market if they differentiate their meat using the indigenous “Ojinegra de Teruel” claim than using the undifferentiated strategy they are undertaken now.
