The Effects of Crossbreeding on Meat Fatty Acids Profile in Qazvinian Native Goats
The study was conducted to investigate the fatty acid profile of intramuscular fat in longissimus lumborum (LL) of three genotypic groups: Qazvinian native (Q, n=10), crossbred Qazvinian native × Saanen breed (QS, n=10) and backcrossed Qazvinian native × Saanen breed (QSS, n=9) male kids.All of kids were weaned at 75-days-old and then fed with a diet consisted of concentrate (70%) and alfalfa h...
متن کامل1 Fundamental Aspects of Crossbreeding of Sheep : Use of Breed Diversity to Improve Efficiency of Meat Production
Breed diversity is a valuable resource of the sheep industry. Crossbreeding systems use breed diversity to increase productivity relative to purebred flocks. Crossbreeding systems vary in managerial complexity and in use of beneficial effects due to crossbred ewes and lambs. Efficiency of meat production is maximized in terminal crossbreeding systems by use of specialized sire breeds to complem...
متن کاملA Review of the Current Status of Goat Research and Development in South Africa
Large areas of South Africa are only suitable for animal production off natural veld, and it is in these ecosystems that the goat has the biggest potential. Developing this potential, however, will require a co-ordinated and multi-functional approach where subject matter specialists work together as a team. Past research and development initiatives in South Africa have concentrated largely on t...
متن کاملAssociation between Melatonin Receptor 1A (MTNR1A) Gene Polymorphism at the MnlI Site and Production Traits in Shal and Crossbreeding between Shal and Romanov
The objective of this study was to evaluate the relationship between polymorphism at the MnlI site of MTNR1A gene and production traits of Shal and Romanov crossbreeding. The crossbreeding between Shal and Romanov was done on 600 Shal ewes. For this reason, Shal ewes were laparoscopically and artificially inseminated with the semen of Romanov breed. For the preparation of genomic DNA, a total o...
متن کاملGenome‐wide population structure and admixture analysis reveals weak differentiation among Ugandan goat breeds
Uganda has a large population of goats, predominantly from indigenous breeds reared in diverse production systems, whose existence is threatened by crossbreeding with exotic Boer goats. Knowledge about the genetic characteristics and relationships among these Ugandan goat breeds and the potential admixture with Boer goats is still limited. Using a medium-density single nucleotide polymorphism (...
