Abstract: -The objective of this study was to evaluate the effect of a short-term supplementation with rice bran (2 kg/cows/day) on the endocrine and metabolic profiles and hepatic gene expression, associated with the reproductive response in beef cows in grazing conditions. Thirty-eight primiparous beef cows (Hereford, Angus and Hereford × Angus) were used in a randomized block design according to genotype, calving date and body condition score at calving (BCS). At 64±14 days postpartum (day 0 of the experiment), cows … Show more

“…Similar to previous results in whole rice bran‐supplemented beef cows in rangelands conditions (Astessiano et al., ), sorghum supplementation did not affect hepatic INSR mRNA in cattle, which would suggest, at least in this aspect, that hepatic insulin sensitivity was not modified. Moreover, in ruminants, it has been indicated that insulin has greater effects on the disposal of glucose at non‐hepatic tissues than on hepatic output of glucose (Brockman, ).…”

“…According to these effects, changes in glucose homeostatic mechanisms by the inclusion of grain in the diets of ruminants fed temperate pastures would be expected and would be probably influenced by feeding management. Short‐term supplementation with whole rice bran or a mix of corn grain and soybean meal has been evaluated to improve the reproductive performance of beef cows or ewes grazing native pastures (Viñoles et al., ; Astessiano et al., ). These studies have demonstrated an increase in glucose and insulin concentrations following concentrate supplementation (Viñoles et al., ; Astessiano et al., ).…”

“…The effect of the pre-mating supplementation on BCS is not consistent and seems to depend, at least partially, on the supplement used. Astessiano et al (2013) and Soca et al (2013) used a supplement based on whole rice bran and reported no effect on BCS. However, cows grazing on pasture improved with Lotus subbiflorus cv.…”

“…The main cause of reproductive failure is the prolonged postpartum anestrus, induced by undernutrition (Short et al, 1990;Hess et al, 2005) and suckling (Williams, 1990). The nutrient supply of grasslands during the winter is insufficient to meet the requirements of the growing fetus in the last third of the pregnancy period, causing a negative energy balance that continues during early postpartum due to the demand for milk production (Bell, 1995;Astessiano et al, 2013). The negative energy balance is evidenced by a decrease in body condition score (BCS) and endocrine changes, such as an increase in non-esterified fatty acids (NEFA) and a decrease in glucose and insulin, which have a negative impact on follicle growth and ovulation (Wiltbank, 1970;Mulliniks et al, 2011).…”
