Desempenho de vacas mestiças em função de suplementação energética e proteica em dietas à base de silagem de milho

Abstract: Objetivou-se avaliar níveis de concentrados energéticos e proteicos sobre o desempenho de vacas leiteiras Holandês x Zebu, com peso corporal de 452±77kg, de terceira e quarta lactação, 80 dias pós-parto e produção de 12,8kg de leite/dia. Nove vacas foram distribuídas em três quadrados latinos 3x3, em períodos experimentais de 10 dias, distribuídas segundo número de lactações, sendo os tratamentos níveis de farelo de soja (FS) em substituição ao fubá de milho (FM) (0,8; 1,6 e 2,4kg/vaca dia, completando para 3,… Show more

“…When analyzing Table 4, it can be observed that the estimated TDN and CP content were 4.8% and 3.7% lower than the nutritional requirements presented by the integrated ration calculation worksheet (Lana, 2020a). Another observation is that the protein left free choice in the pasture contributes little to the nutrient supply (Table 4), and the supply of concentrate is important for the additional supply of energy and protein for milking Holstein Gyr crossbred cows at pasture (Lana et al, 2011;Vargas et al, 2013).. There was no significant effect (P>0.05) of treatments on milk production, and the average daily production observed was 13.4 kg of milk (Table 5).…”

“…When analyzing Table 8, it shows that the estimated TDN and CP content were 5.9% higher and 2.9% lower, respectively, than the nutritional requirements presented by the integrated ration calculation worksheet (Lana, 2020a). The supply of concentrate is important for the additional supply of energy and protein for Holstein Gyr crossbred dairy cows at pasture (25% and 39% of the total, respectively; Lana et al, 2011;Vargas et al, 2013).…”
