Abstract
Nutrition is an integral component of livestock production industry that determines reproductive capacity, fertility, estrus cyclicity and production potential of an individual livestock. Lower energy intake leads to an increase in the length of anestrous period whereas and higher intake causes “fatty cow syndrome”. Body condition score (BCS) helps in determination of energy status of an animal. Similarly higher level of protein in the feed lead to delayed return of normal ovarian function. Feeding high fat diets to cycling heifers and postpartum cows was found to increase progesterone production and enhance the lifespan of the corpus luteum. A negative dietary cation-anion difference (DCAD) prior to calving signifies decreased incidence of metabolic disorders postpartum and maintain reproductive integrity for future lactations.
