O objetivo deste trabalho foi avaliar o efeito do sistema de plantio direto (PD) sobre diferentes quantidades de palhada, na eficiência de uso da água e na produção de repolho. Foram utilizadas quatro quantidades de palhada de milho sobre um Latossolo Vermelho de textura argilosa (0,0, 4,5, 9,0, 13,5 Mg ha-1 de matéria seca), com o sistema de plantio convencional (PC) como controle. O delineamento experimental utilizado foi o de blocos ao acaso com três repetições. O estande de plantas, a produtividade, a massa de matéria fresca, o diâmetro, a altura e a compacidade de cabeças de repolho não foram afetados significativamente pelos tratamentos. Houve uma redução de até 13% na lâmina líquida de água aplicada durante o ciclo do repolho cultivado em sistema de PD com palhada, quando comparada à utilizada em tratamentos sem palhada. Durante os primeiros 30 dias após o transplante de mudas, a economia de água chegou a 28%. O índice de produtividade da água em sistema de PD apresentou incremento linear com o aumento da quantidade de palhada utilizada, e foi até 21% maior que no sistema de PC. |

The aim of this study was to evaluate the effects on feed intake, heifer performance, and health of increasing the total solids (TS) content of liquid feed (whole milk) by adding increasing amounts of milk replacer powder during the pre- and postweaning periods. Crossbred Holstein-Gyr heifers (n = 60) were assigned to 1 of 4 treatments (n = 15 per group), which consisted of different TS concentrations: 12.5, 15.0, 17.5, and 20.0% of liquid feed. Heifers received 6 L of liquid feed per day, divided into 2 equal meals (0800 and 1600 h) and provided in buckets, from 5 to 55 d of age. From 56 to 59 d of age, the total amount of liquid feed was reduced by half, maintaining only morning feedings. Heifers were weaned at 60 d and monitored until 90 d of age. Water and starter were provided ad libitum during the entire experiment. Corn silage was included in the diet during the postweaning period (70 d of age). Feed intake and health scores were evaluated daily. Body weight and body frame development were recorded weekly. Starting at 14 d, ruminal pH was measured every other week. Laboratory analysis determined that the actual TS contents of the liquid feed were 13.5, 16.1, 18.2, and 20.4%, for the proposed 12.5, 15.0, 17.5, and 20.0% TS treatments, respectively. The osmolality of liquid feed treatments was 265 to 533 mOsm/L. Intake of liquid feed was similar among treatments from 4 wk of age. During the preweaning period, starter intake, fecal score, and days with diarrhea were similar among treatments. Ruminal pH at weaning averaged 6.2 and was similar among treatments. Increasing concentrations of TS in the liquid feed were associated with linear increases in average daily gain, final body weight, and growth performance, but linear decreases in feed efficiency. During the postweaning period, intake of starter, corn silage, and water were similar among treatments, as well as average daily gain and feed efficiency. Final body weight and growth performance during the postweaning period also increased linearly with concentration of TS in liquid feed. Increasing the concentration of TS in liquid feed up to 20.4% increased performance and body frame development in dairy heifers during the pre- and postweaning periods and had no effects on solid feed intake or health.
