Book excerpt: The effects of nutrition during late gestation and after insemination, as well as the effects of energy reserves on reproductive function of the beef female and subsequent growth and reproductive function of their offspring were investigated. The aims of this research were: 1) to evaluate how a change in nutritional intake immediately after insemination would affect pregnancy success and concentrations of hormonal mediators, IGF-I and progesterone, 2) to determine the influence that postpartum energy reserves have on embryo viability, early embryonic development, and embryo quality, and 3) to evaluate the impact that maternal protein supplementation of irrigated meadow grass hay during the last trimester of gestation has on cow BW and BCS, calf birth and weaning BW, conception rates of heifer offspring, and feedlot performance of steer offspring. Findings from Chapter III show that suppression in nutritional plane of heifers during the 21-d following AI has a negative impact on heifer performance, circulating concentrations of IGF-I, and AI pregnancy rates. Thus, it is biologically beneficial to ensure that heifers maintain their pre-breeding plane of nutrition during the 21-d following AI. Chapter IV presents evidence that cows with BCS 5.4 tend to produce more total embryos after a superovulation program compared to cows BCS 4.3. Additionally, peripheral concentrations of IGF-I were greatest in cows with a BCS 5.4, which may be an indicator of a more suitable environment in the uterus for further development of an embryo. In Chapter V, cows supplemented with protein during the last trimester of gestation had a greater BW gain and BCS change by calving time. Weaning BW of calves born to protein supplemented dams was greater when compared to calves from non-supplemented cows. There was a trend for pregnancy rates of heifers born supplemented dams to be 16 percentage points greater (95% vs. 79%). And although dam supplementation did not seem to affect intakes, gains, feed efficiency or carcass characteristics on the male progeny in this study, advantages have been observed other peer-reviewed research studies that support the concept that late gestation supplementation can have an impact subsequent progeny.
