The effects of lactation status and body composition on reproductive perfpr,amce were studied in seventy=one mature Brangus cows, thirty-eight non-lactating (NL) and thirty-three in late lactations (L). During Phase I (192 days) both groups were fed a low energy diet (50% NRC recommendation). During Phase II (65 days) a high energy diet (120% NRC recommendation( was fed to 19 of the non-lactating cows (NL-H) and to 17 of the lactating cows (L-H). The other non-lactating and lactating cows remained on the low energy diet (NL-L and L-L). Energy restriction durint Phase I did not affect ovarian activity although losses in body weight and condition were substantial. Rapid changes in dlcy weight, condition, and percent empty body lipid (EBLP) during Phase II did not substantially influence fertility although a five-fold difference in EBLP was observed (NL-H vs. L-L). Treatment groups did not differ (P> .05) in conception rate, days to breeding, days to conception, conception at first service, and number of services per conception. It appears that changes in body weight and composition have little effect of likekihood of pregnancy in non-lactating and latelactating beef cows once estrous cycles are initiated. |
