Live weight (LW) losses of beef calves during winter has always been a great hindrance in the path of intensification and profitability improvement of extensive livestock farmers, especially concerning native grasslands-based systems placed on sandy soils in Uruguay. Additionally, labour shortage has been an increasing concern to farmers, since both availability and training of human resources have been continuously declining over the years. To address these two issues trough research and innovation, an experiment was set out aiming to determine whether it could be possible to attain similar animal performances through supplementing beef calves in their first winter using self-feeders compared to daily supplementation. |

ABSTRACT
The effect of level of CP fed during late gestation on reproductive performance and milk production was studied in multiparous cows. Sixty-eight pregnant Angus cows were used. At 121 d prepartum, cows were blocked by BW (409 ± 57 kg) and expected calving date, randomly assigned to a low-protein (LP = 6% CP) or high-protein diet (HP = 12% CP), and allocated to 12 pens per treatment. After parturition, all cows were managed in a single group until weaning. Body weight and BCS
were determined at the start of the experiment, at calving, and at weaning. Progesterone was quantified weekly to indicate luteal activity and estimate interval to first estrus. Milk production was measured until weaning. The HP cows had greater BW gain during the prepartum period (P < 0.01) and tended to gain more BCS (P = 0.06) than LP cows. The prepartum diet did not affect gestation length (P = 0.44) or interval from calving to the onset of luteal activity (P = 0.35). Pregnancy rates, milk quality, and production were not influenced by dietary treatments. In conclusion, protein level prepartum in multiparous beef cows affected the BW change at calving, without consequences on reproductive performance and milk quality and yield. |
