Abstract

Rib bone biopsy samples are often used to estimate changes in skeletal mineral reserves in cattle but differences in sampling procedures and the bone measurements reported often make interpretation and comparisons among experiments difficult. 'Full-core' rib bone biopsy samples, which included the...

Abstract

The aim of this study was to investigate the persistent infection (PI) of bovine viral diarrhea virus (BVDV) along with its coexistence between BVDV antibody titer and BVD virus in blood of Holstein dairy cows. Only large commercial farms (each contained <1000-3000 unvaccinated cows) were included. There were 11 dairy cattle herds. They included nearly 20,000...

Abstract

Genomic prediction is widely used to select candidates for breeding. Size and composition of the reference population are important factors influencing prediction accuracy. In Holstein dairy cattle, large reference populations are used, but this is difficult to achieve in numerically small breeds...

Abstract

Displacement of abomasum (DA) is one of the most common and important disorders in dairy cattle. The objective of the present study was to detect the quantitative trait loci (QTL) for DA in Chinese Holstein using single-step genomic BLUP methodology. A total of 60,556 producer-recorded DA event...

Abstract

Background: Urine concentration (UC) provides clinically useful information concerning hydration status and renal function of animals. Objectives: To characterize the clinical performance of urine specific gravity measured by optical refractometry (USG-R) or Multistix-SG urine reagent dipstick (U...

Abstract

Defensins especially β-defensins participate in innate immunity to prevent microbial infection of female reproductive system, one of the most important problems in mammal species. So, the purpose of this study was to investigate the presence of polymorphism in β-defensin gene (C/T: position 2239)...

Abstract

Genetic evaluation of female fertility in Danish, Finnish, and Swedish dairy cows was updated in 2015 to multiple-trait animal model evaluation, where heifer and cow fertility up to third parity are considered as separate traits. A model for conception rate was also developed, which required...

Abstract

Genotype by environment interaction (G × E) effects for lactating cows' fertility traits may differ with lactation number when accounting for herd production level. Our objective here was to investigate the genetic correlations among three fertility traits in cows and lactation persistency within...
