An Enhanced Body Condition Improved Sexual Behavior, Ovarian Structure and Function, and Reproductive Fitness in Rangeland-Crossbred Dairy Goats

The possible effect of body condition score (BCS) on ovarian function, sexual behavior, (i.e., females and males; appetitive consummative), estrus, ovulation, reproductive performance was investigated in crossbred dairy goats under extensive conditions. Based their BCS, female (n = 48) were divided into two experimental groups, either with a low (LG; 1.0 ± 0.2 units; n 26) or high BCS (HG: 2.5 0.9 22). Bucks 4; cc 2.5.
