Research ArticleOpen accessPhrase in the titleGenotype Screening of Bovine Brachyspina in Taiwan Holstein CowsChun Hsuan Chao, Yi Ming Chen, Kuo Hua LeeThis study analyzed carrier frequencies of the genetic defect bovine brachyspina (BS) in the Holstein cows in Taiwan. In total, 1688 cows from 31 herds were included in the analysis, performed using the Igenity-Prime 50K single-nucleotide polymorphism chip. Of the 1688 cows, 68 (5.09%) were BS carriers (BY), a frequency lower than that reported in Taiwan previously. In Taiwan, the … …American Journal of Animal and Veterinary Sciences, Vol. 15, Issue 3 · 14 Aug 2020 · 6,971 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleEFFECT OF PUERPERAL METRITIS ON HOLSTEIN COWS PRODUCTIVE, REPRODUCTIVE VARIABLES AND CULLING RATESA. Dawod, Byeng R. MinThe objective of the study was to determine the effect of puerperal metritis prevalence in high yielding Holstein cows on productive (305 days, actual milk yields), reproductive (days to first estrus, days open and services per conception) variables and culling rates.

Several factors may affect embryo production including age and season. In this study, the effects of age and season on in vivo embryo production were evaluated on Friesian Holstein (FH) cows. A total … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 1 · 2 Mar 2024 · 5,457 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleMarking of Genetic Resistance to Chlamydia, Brucellosis and Mastitis in Holstein Cows by Using Polymorphic Variants of LTF, MBL1 and TLR9 GenesIndira Beishova, Birzhan Nurgaliyev, Alena Belaya et al.The purpose of the research is to study the association of polymorphic variants of the Toll-Like Receptor 9 (TLR9), Mannose-Binding Lectin 1 (MBL1), and Lactoferrin (LTF) genes with the incidence of chlamydia, brucellosis and mastitis in Holstein cows. Samples of Holstein cows with established diagnoses of chlamydia, brucellosis, and mastitis were characterized by the nature of the correspondence of the … …American Journal of Animal and Veterinary Sciences, Vol. 18, Issue 2 · 6 May 2023 · 6,157 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleThe Effect of Rumen Acid Load on Postpartum Performance and Blood Metabolic Responses in Transition Holstein CowsSadjad Danesh Mesgaran, Alireza Vakili, Alireza Heravi Moosavi, Ghasem KoolabadiProblem statement: The transition period is the most stressful time in the production cycle of a dairy cow because of depressed feed intake, endocrine and metabolic changes at parturition. The aim was to determine the effect of rumen acid load on postpartum performance and metabolic parameters in transition Holstein cows. Approach: The Acidogenicity Values (AV) of the diets were determined … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 1 · 25 May 2011 · 7,438 accessesView PDFCite
