In this study we performed comprehensive search for QTLs focusing on single nucleotide polymorphisms (SNPs) associated with growth and meat traits in sheep. The database contains information about 156 SNP–trait associations (123 unique SNPs) and a list of 165 associated genes. The updated information is freely available at https://github.com/Defrag1236/Ovines_2018.

Goat breeds in Iran are various. People use goat products for food in addition to clothing. Among goat breeds, the Markhoz (Iranian Angora) is one of the most notable in the northwest of Iran (mainly the Kurdistan region) with valuable mohair. The purpose of this study was to search for a way to genetically improve reproduction as well as fertility to increase their population. Based on the results of this research, a high-fecundity doe can be screened; hence flock parturition will improve.

In this study, semen seminal plasma contents and the motility of sperm cells in Capoeta trutta were determined via a computer-assisted sperm analysis system. In addition, we evaluated the relationship between semen seminal plasma ions and the velocities of sperm cells. Finally, we hope that the present information on the motility parameters of Capoeta trutta in this paper will eventually help artificial insemination in reproduction practices.

Polyunsaturated fatty acids play an important role in a wide variety of physiological processes. They are produced by a series of chemical reactions. One of the enzymes converting such acids is a delta 6 desaturase encoded by the FADS2 gene. Therefore, we aimed to determine possible associations between the polymorphism in this gene and milk fatty acid composition in dairy cattle. An identified substitution could be used as a potential genetic marker for fatty acid composition in bovine milk.
