Abstract

ABSTRACT The objective was to evaluate the supplementation of fat-soluble and water-soluble vitamins on the performance and plasma concentrations of vitamins in modern hybrids pigs. A total of 144 commercial hybrid castrated male, 43.531 ± 1.099kg, were used in a randomized block design with six treatments, eight replicates and three animals per pen. The experimental treatments were different vitamin supplementation levels - 0, 25, 50, 75, 100, and 125% of the recommended by Rostagno et al. (2011) for male pigs in growth I (40 to 50kg), growth II (50 to 70kg), and finishing I (70 to 90kg) phases. For growth phases I and II, a linear effect (P<0.05) due to increase in vitamin supplementation was observed on performance. For finishing phase I and total phase, a linear effect (P<0.05) was observed with increased final average weight (FAW) and improved feed conversion ratio (FCR). For average daily weight gain (ADWG) and average daily feed intake (ADFI) a quadratic effect was observed (P<0.05). A linear (P<0.05) increase in plasmatic α-tocopherol and B12 was observed with the 125%. Thus, it is concluded that the 125% vitamin supplementation improved performance of modern hybrids pigs (40 to 90kg).

提高脂溶性和水溶性维生素水平对现代杂交猪生长肥育期生产性能和血浆维生素浓度的影响

摘要本研究旨在评价添加脂溶性和水溶性维生素对现代杂交猪生产性能和血浆维生素浓度的影响。共有144只商业杂交阉割雄性，43.531±1.099kg，用于随机分组设计，共有6个处理，8个重复，每个围栏3只动物。实验处理是不同的维生素补充水平——Rostagno等人（2011）推荐的0、25、50、75、100和125%，用于生长期I（40至50公斤）、生长期II（50至70公斤）和结束期I（70至90公斤）的雄猪。对于生长阶段I和II，由于维生素补充的增加，观察到对表现的线性影响（P<0.05）。对于精加工阶段I和总阶段，随着最终平均重量（FAW）的增加和饲料转化率（FCR）的提高，观察到线性效应（P<0.05）。平均日增重（ADWG）和平均日采食量（ADFI）呈二次效应（P<0.05），血浆α-生育酚和B12呈线性（P<0.05）增加，增加125%。因此，可以得出结论，补充125%的维生素可以提高现代杂交猪（40至90kg）的性能。
