Megjegyzések:Dorper (DO) is a meat-specialized hair composite breed, intensively selected for growth rates, carcass quality,unselective grazing. The aim of the current comparative study was to evaluate the adaptability and performance ofDO breed under Hungarian and Romanian rearing conditions. DO breed was introduced into Hungary to DebrecenUniversity in 2008. Under Hungarian rearing conditions the DO breed maintained its non-seasonal reproduction andreproductive precocity, with maiden ewes being put to ram starting the age of 9 months. Lamb crops of 2 weaned peryear are common under proper management and feeding conditions. In Romania DO breed was introduced starting2007, with the heard-book and genetic improvement plan of the breed being established in 2009. Under Romanianfarming conditions the DO rams are usually used as terminal sires which are crossed with indigenous Turcana andTsigai breeds, being preferred by the farmers to sire the crossbreds because of the high growth rates and nonselectivegrazing of the crossbreds. Fertility of DO ewes and survival rates of the DO sired lambs until weaning werenot affected when compared to native Turcana breed. It was concluded that DO breed has adapted and performsextremely well under both Hungarian and Romanian rearing conditions.

Cím:Reproduction Efficiency and Health Traits in Dorper, White Dorper, and Tsigai Sheep Breeds under Temperate European Conditions / Gavojdian Dinu, Budai Csilla, Cziszter Ludovic Toma, Csizmár Nikolett, Jávor András, Kusza Szilvia

Megjegyzések:The objective of the current pilot study was to evaluate the reproductive performance and health indicators in Dorper, White Dorper, and Tsigai breed ewes managed semi-intensively under European temperate conditions. A total of 544 ewe-year units were observed, with ewes (ranging from 1.5 to 8 years of age) managed under identical rearing conditions for a period of two consecutive production cycles (2012 through 2013 and 2013 through 2014). In general, significant (p?0.001) genotype-related disparities were found in occurrence rates for all health parameters taken into study. Clinical mastitis incidence was significantly lower (p?0.05) in Dorper (9.4%) and White Dorper (10.8%) breeds compared to that of Tsigai ewes (17.4%). Significant differences (p?0.05) for lameness were found between Dorper and Tsigai breeds, with occurrence rates of 8.0% and 2.9%, respectively. Incidence for pneumonia and abortion was not influenced (p>0.05) by the ewes' genotype. Litter size was significantly lower (p?0.05) in White Dorper breed than for Dorper and Tsigai ewes, of 1.21, 1.40, and 1.45, respectively. Conception rates and lambs survival were not affected (p>0.05) by genotype. Results suggest that South African Dorper and White Dorper sheep breeds have adapted well to the specific rearing conditions.
