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 ...

Only a limited number of studies looking into the impact of milking intervals on milk yield in cows milked in automatic milking system (AMS) have been conducted. The purpose of this study was to analyse changes in milking ...

The activity of calves depends mainly on the way they are housed and not on their age. Because compromised welfare early in life may affect the profitability of future production, calves need to be fed colostrum after ...

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 experiment carried out aimed to examine the effectiveness of two methods of assessment of the parameters of sperm motility in thawed semen depending on the degree of its dilution. The semen was collected from 12 ...

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 ...

In 2021, 12,088 accidents involving animals were reported to the Regional Branches and Local Units of KRUS in Poland: 10.2% more than in 2020. The most common causes of such acci- dents are poor housing conditions and a ...
