Abstract

Transrectal palpation of the reproductive tract is the most common method for pregnancy determination in cattle and is considered a veterinary skill that new veterinary medicine (DVM) graduates should perform proficiently. However, using privately owned cattle to train students can be difficult...

Abstract

The European Community's leukosis key (EC key) is a well-known hematologic method for detecting bovine leukemia virus (BLV) infection in dairy cattle. The key identifies infected cattle with persistent lymphocytosis via a combination of lymphocyte count (LC) and age. Using the EC key to identify...

Abstract

The European Community's (EC) Key, which is also called Bendixen's Key, is a well-established bovine leukemia virus (BLV) diagnostic method that classifies cattle according to the absolute lymphocyte count and age. The EC Key was originally designed for dairy cattle and is not necessarily suitable...

Abstract

Depending on the objectives (economic, sociology, epidemiology...), many different methods and data are used to classify cattle herds. The use of different and not well defined herd classifications makes it difficult to compare the results of studies between but also within countries. Our aim was...

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)...
