ABSTRACT - The objective of this work was to evaluate the effects of nutritional plans and breed composition on nutrient intake and digestibility, nitrogen balance, and performance of dairy heifers in tropical conditions. Thirty-six heifers - 12 Holstein, 12 Gyr, and 12 Gyrolando F1 (½ Holstein × ½ Gyr) - were housed in a tie-stall system and randomly distributed, adopting a completely randomized design in a 3×3 factorial arrangement (nutritional plans and breed composition). The diets were formulated to enable weight gains of 200, 400, and 800 g per day, corresponding to the nutritional plans 11, 14, and 19 g kg-1 body weight (BW), respectively. The intake of dry matter, fibrous fractions (g kg-1 BW-0.75), and metabolizable energy (kcal-1 BW-0.75) in the 11-g kg-1 plan were greater for Gyr heifers than for Gyrolando and Holstein heifers. Ether extract digestibility was 13.85% higher for Gyr heifers compared with Gyrolando F1 in the 19-g kg-1 plan. The increase in the nutritional plans shows a quadratic response to nutrient intake and a linear response to average daily gain, but does not affect the digestibility coefficients. Gyr and Gyrolando F1 heifers present similar nutritional efficiency to that of Holstein heifers. RESUMO - O objetivo deste trabalho foi avaliar os efeitos do plano alimentar e do grupo racial sobre o consumo e a digestibilidade de nutrientes, o balanço de nitrogênio e o desempenho de novilhas leiteiras em condições tropicais. Trinta e seis novilhas - 12 Holandês, 12 Gir e 12 Girolando F1 (½ Holandês × ½ Gir) - foram alojadas em sistema ?tie-stall? e distribuídas aleatoriamente, tendo-se adotado delineamento inteiramente casualizado, em arranjo fatorial 3x3 (planos alimentares e grupos raciais). As dietas foram formuladas para possibilitar ganhos de peso de 200, 400 e 800 g por dia, correspondentes aos planos alimentares de 11, 14 e 19 g kg-1 de peso corporal (PC), respectivamente. As novilhas Gir dentro do plano de 11 g kg-1 consumiram mais matéria seca, fração fibrosa (g kg-1 de PC-0,75) e energia metabolizável (kcal de PC-0,75) do que as novilhas Girolando e Holandês. A digestibilidade do extrato etéreo foi 13,85% superior para as novilhas Gir, em comparação às Girolando F1 no plano de 19 g kg-1. O aumento do plano nutricional tem efeito quadrático no consumo de nutrientes e linear no ganho de peso médio diário, mas não influencia o coeficiente de digestibilidade. Novilhas Gir leiteiras e Girolando F1 apresentam eficiência nutricional semelhante à das novilhas Holandês.

Little is known about the effects of neotropical mound-building termites in soil chemical and physical properties. The influence of soil termite activity on soil characteristics was studied by assessing chemical, physical and micromorphological properties of a toposequence of Latosols (Oxisols). Soil samples were collected from the walls and inner parts of termite mounds and also from adjacent soil. A high diversity of termite genera was found in the mounds along the toposequence, together with the inquiline termites and other soil-dwelling arthropods. Chemical analyses showed that pH and the contents of organic C and N, P, Ca and Mg were significantly higher in termite mounds compared with adjacent areas, with an inverse trend forAl content. Significant differences in pH and exchangeable Al were observed between soil and mound across the slopes. The mound density across the landscape was higher at the upper slope segment, followed by the hill top, middle slope and lower slope segments. Considering a lifespan of 30 years and dimensions of termite mounds found in the toposequence we conclude that the textural and chemical uniformity of Latosols may be increased, following the pedobiological turnover during mound building, with local rates varying from 2.1 to 7.5 m3ha?1. |
