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.

Green manure is a soil management technique which provides several benefits to agroecosystems, improving the chemical, physical and biological quality of the soil, allowing them to provide different ecosystem services. Thus, the purpose of this work was to select green manures to compose multifunctional agroecosystems that provide ecosystem services in a semi-arid environment through the addition of biomass, C and N, and nutrient cycling. Thus, 29 treatments were evaluated in two cultivation cycles, using 14 species of legumes, oilseeds and grasses, distributed in single and intercropped crops. The green manures were cut at 70 days after sowing, and samples of the shoot and root parts were collected, with the production of fresh and dry biomass and the N, P, K, Ca, Mg and S levels being evaluated. C and biomass from rhizodeposition were also estimated. From these data, the accumulation of nutrients in the shoot and root biomass was calculated. Data were compared using descriptive and multivariate statistics. There is a positive relationship between the growing number of species used in consortium and the greater production of shoot and root biomass, favoring the increase in the capacity of the agroecosystem to provide provision and regulation services, with the latter being associated with climate change mitigation measures, highlighting the importance of biodiversity. |
