Sheep breeding has an important role in animal production in Turkey. The diversity of animal genetic resources of Turkey have not been fully appraised and some indigenous farm animal breeds are in danger of disappearing even before being scientifically defined. An equilibrium is needed between the genetic improvement studies and the conservation of the genetic resources Ozcan et al (1994). The greatest part of the wool produced by the indigenous sheep breeds in Turkey is of coarse and mixed type of wool and most of it is used in the hand woven authentic carpet production Kizilay (1986). This paper reports body weights and wool production characteristics of the indigenous Red Karaman and Karayaka sheep breeds.

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.

Growth and meat production traits are very important in sheep breeding. Cyp19 gene has a major role in reproductive activity and growth due to its function in estrogen synthesis. Another gene affecting growth traits is  Myostatin (MSTN) gene, which mainly regulates skeletal muscle growth. In this study allele frequencies of genetic polymorphism in Cyp19 and Myostatin genes were identified by PCR-RFLP method in five indigenous Turkish sheep breeds, Chiose, Imroz, Kivircik, Zom and Morkaraman. Digestion of Cyp19 gene with HaeIII only revealed uncut AA genotype and digestion of MSTN with DraI also revealed only uncut AA genotype. Both loci analyzed in this study were found to be monomorphic in five Turkish indigenous sheep breeds. These highly conserved parts of the two genes can be useful for molecular evolutionary studies in sheep. Further studies regarding association analysis of Cyp19 and MSTN in sheep should be conducted.

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

<p>En Pakistán los recursos genéticos ovinos son abundantes, disponiéndose de varias diferentes castas extendidas en todo el país. No obstante, la diversidad molecular de las razas de ovejas es poco conocida en la región. Por ello, en el presente estudio se investigaron 16 marcadores microsatelitales de las razas indígenas Buchi y Hashtnagri, en las provincias de Pendjab y Balochistan respectivamente. Para indagar la diversidad genética se obtuvieron muestras de sangre de 25 animales de cada raza. El promedio del número de alelos en Buchi y Hashtnagri fue de 3,375±1,455 y 3,50±1,591 respectivamente. Los promedios de heterocigosis registradas fueron de 0,878±0,204 para la raza Buchi y 0,885±0,218 para Hashtnagri. Los índices de Shannon fueron 1,032±0,371 para Buchi y 1,070±0,412 para Hashtnagri, respectivamente. La estimación de los coeficientes de endogamia (FIS y FIT) mostró valores negativos, en tanto que el flujo genético (migración) fue de 10,09 y el promedio de la diferencia poblacional (FST) resultó de 2,4%. En ambas razas, el índice de información polimórfica fue 0,56, indicando el valor del marcador del tablero. Entre las ovejas Buchi y Hashtnagri, la distancia genética estándar de Nei (Ds) fue 0,0218. Según estos resultados, ambas razas mostraron considerable diversidad genética. Los datos obtenidos permiten vislumbrar una promisoria mejoría en el área de la conservación y en el diseño de las estrategias para la cría de ovejas en el futuro cercano.</p>
