Impacts of Metabolism and Nutrition During the Transition Period on Fertility of Dairy Cows
In early postpartum, high-producing dairy cows undergo a period of extensive tissue catabolism because of negative nutrient balance. Metabolic unbalances can lead to diseases, which are known to depress fertility in dairy cows. Negative nutrient balance has been associated with compromised immune and reproductive functions in dairy cows, and a compromised immune system leads to greater risk of ...
متن کاملInteractions between negative energy balance, metabolic diseases, uterine health and immune response in transition dairy cows.
The biological cycles of milk production and reproduction determine dairying profitability thus making management decisions dynamic and time-dependent. Diseases also negatively impact on net earnings of a dairy enterprise. Transition cows in particular face the challenge of negative energy balance (NEB) and/or disproportional energy metabolism (fatty liver, ketosis, subacute, acute ruminal acid...
متن کاملThe role of rumen-protected choline in hepatic function and performance of transition dairy cows.
High-producing dairy cows enter a period of negative energy balance during the first weeks of lactation. Energy intake is usually sufficient to cover the increase in energy requirements for fetal growth during the period before calving, but meeting the demand for energy is often difficult during the early stages of lactation. A catabolic state predominates during the transition period, leading ...
متن کاملNutrition and Reproduction in Dairy Cattle
Nutrition has an important impact on the reproductive performance of dairy cattle. Energy is the major nutrient required by adult cattle, and inadequate energy intake has a detrimental impact on reproductive activity of the female bovine. Cows under negative energy balance have extended periods of anovulation. Postpartum anestrus, as well as infertility, is magnified by losses of body condition...
متن کاملRelationship between Insulin to Glucagon Ratio and Metabolic Parameters in Primiparous and Multiparous Dairy Cows in Transitional Period
In order to investigate the relationship between insulin to glucagon ratio and metabolic factors in transitional period of dairy cows, 28 cows heifers with body condition score of 3.25- 3.75 were selected. Dairy cows received close up diet, from 21 days prepartum until parturition and lactation diet according to nutritional requirements after parturition. Blood was sampled at 10 days before and...
