Effect of temperament of Jersey and Holstein Friesian cows on milk production traits and somatic cell count.

Abstract: Abstract. The aim of present study was to investigate the relationships between temperament score and milk production, as well as somatic cell count in a herd of Jersey and Holstein Friesian breeds. The temperament of 283 Jersey and 69 Holstein Friesian cows were assessed (scored) by the temperament score test (behaviour of animals was assessed in a 5-score system (1: calm, 5: nervous) while spending 30 s on the scale during weighing). The daily milk yield, fat, protein content and somatic cell count were also investigated in this study. Our investigation did not reveal any correlation between daily milk yield and temperament score. But milk somatic cell count was showed positive moderate relation with the temperament scores of Jersey (rrank=0.67; P=0.0001) and Holstein Friesian (rrank=0.66; P=0.0001) cows. Calmer cows had lower somatic cell count (Jersey: 135.40×103/cm3; Holstein Friesian: 176.07×103/cm3) compared to the more temperamental cows (Jersey: 540.44×103/cm3; P=0.0001; Holstein Friesian: 744.91×103/cm3; P=0.0001, resp.).

Association study of an AvaI and PvuII polymorphism at the porcine estrogen receptor (ESR) gene, with litter size

Abstract: A total of 144 sows housed on 3 commercial pig farms were screened for an Aval and a Pvull polymorphism in the oestrogen receptor (ESR) gene. The association between the Aval-genotype of the sows and the number of piglets born alive in the first parity was significant. Least squares means far number of piglets born alive in the first parity was 9.67 for heterozygous sows (n=35) and 8.33 for homozygous negative sows (n=105). Heterozygous sows had on average also one piglet more in second parity compared with homozygous negative sows. Data of two homozygous positive sows indicate a higher number of piglets born alive than found for the other 2 genotypes. No association was noticed between the Pvull polymorphism and the prolificacy data of the sows.
