Nutrition and Reproductive Efficiency: Transition Period Management, Energy Status, and Amino Acid Supplementation Alter Reproduction in Lactating Dairy Cows
نویسندگان
چکیده
A number of reviews have highlighted the importance of nutrition in regulating bovine reproductive efficiency (Cardoso et al., 2013; Grummer et al., 2010; Santos et al., 2010; Wiltbank et al., 2006). The effects of nutrition in the embryo donor cow have been particularly emphasized (Santos et al., 2008; Sartori et al., 2010; Sartori et al., 2013; Velazquez, 2011; Wu et al., 2013). This review will specifically focus on some of our results related to how changes in nutrition can alter reproductive efficiency of dairy cattle.

High-producing dairy cows are subfertile. Hormonal and metabolic responses associated with homeorrhetic and homeostatic regulatory responses to partition nutrients for lactation, coupled with management, contribute to the reduction in fertility. Systems of reproductive management partially restore herd reproductive performance and provide a basis to access the impact of targeted nutritional str...
متن کاملNutrition, Metabolic Status and Reproductive Efficiency in Dairy Herds
Nutrition of transition period in dairy cows dramatically increases requirements for energy, glucose, amino acids and other nutrients in dairy cows and, parallel to that, feed intake is depressed. An insufficient or imbalanced nutrient intake might lead to the malfunction of organs, causing reproductive failure. To minimize the metabolic/reproductive damage caused by negative energy balance (NE...

Nutrition has a significant effect on reproduction and lactation in Ruminant. Supply of require nutrient of dairy cows and ewes in early lactation is the main challenges that will be considered, since in most cases the animals facing negative energy balance after calving and the beginning of the period of lactation. Negative energy balance may sometimes result in reduced livestock production an...
