Circulating metabolic hormones in different metabolic states of high producing Holstein dairy cows
Background: Information regarding the metabolic hormones in different metabolic states of high producing dairy cows can aid high producing herds to manage and resolve the metabolic and production problems. Furthermore, it can be considered as a tool to evaluate metabolic status of dairy cows. Herd managers can also evaluate the energy input-output relationships by assessing the metabolic profil...
متن کاملAn unusual cause of traumatic reticulitis/reticuloperitonitis in a herd of Swiss dairy cows nearby an airport.
This report describes the findings in five cows from one dairy herd, in which all 31 cows were slaughtered or euthanised because of traumatic reticuloperitonitis. All the cows had numerous thin sharp pieces of metal attached to a magnet in the reticulum, giving the magnet a hedgehog-like appearance. Investigation revealed that the cattle had eaten forage harvested from a field immediately adjac...

متن کاملAssociation of milk yield and body condition score indices with the commencement of luteal activity after parturition in high producing dairy cows
The aim of the present study was to investigate the relation between different indices of milk yield andbody condition score (BCS) with the commencement of the luteal activity (C-LA) during the postpartumperiod in high producing dairy cows. Seventy-one multiparous healthy (free of detectable reproductivedisorders) Holstein dairy cows (mean peak milk yield = 56.7 ± 7.4 kg) were used in the prese...
متن کاملMetabolic profiles of high-yielding dairy cows with ovarian cysts formation
Background: Ovarian cysts are among the diseases which cause reproductive failure and economic losses in dairy herds. High yelding dairy cattles are suseptable to reproductive failure caused by ovarian cysts, as a result of their exposure to stressful coditions during lactation. OBJECTIVES: This study aimed to monitor metabolic profile tests in dairy cows with ovarian cysts in comparison with c...
