The aim of this study was to analyse the dependence between PIT-1 gene polymorphism in exon 6 of bovine chromosome 1 (c.1178G>A) and the level of production progress in Polish Holstein-Friesian Black-and-White cows. The ...

The aim of this study was to analyse dependencies between PRL gene polymorphism within exon 4 of bovine chromosome 23 (locus g.8398G>A), and the level of production progress in milk yield, yields of milk fat and milk ...

The aim of the study was to evaluate the extensity and intensity of gastro-intestinal parasitic infections in Limousine beef cattle in West Pomerania, Poland, and to assess the efficacy of Valbazen (Pfizer Inc., USA) in ...

Polymorphisms of DGAT1, ABCG2, SCD1 and PPARGC1A genes significantly affect the milk, fat and protein yield and chemical composition of milk. Depending on the type of polymorphism, they increase or decrease the milk, ...

Modern farming asks many questions which science has answers to. While selecting animals for further breeding, many aspects should be taken under consideration, like an animal's phenotypic and genetic features. Marker-assisted ...

The aim was to establish possible associations between the g.14791C>T and g.14589A>G SNPs in the SLC27A1 gene and milk production traits as well as somatic cell count in milk of Jersey cows. No significant associations ...
