Two concentrates, one protein-rich and one based on cereals, were combined with two silages with a crude protein content of 17 and 13% of dry matter (DM), respectively to give four different diets for...
Polymorphism identification in goat DGAT1 and STAT5A genes and association with milk production traits
milk yield fat percentage dairy goat SNP PCR-RFLP SSCP additive effect
2015/6/24
Polymorphisms of DGAT1 and STAT5A genes in Xinong Saanen and Guanzhong goat breeds were investigated. PCR-RFLP, SSCP, and DNA sequencing were used to identify three SNPs: DQ380250:g.407_408insC in the...

volume of residual milk in relation to milk flow curves in breeds Tsigai, Improved Valachian, and Lacaun...
Lactation curves for milk yield, fat, and protein content in Slovenian dairy sheep
dairy sheep milk traits test-day records
2015/6/23
Lactation curves for daily milk yield, fat, and protein content in three dairy sheep breeds were
