This review paper discussed the nutritional and functional roles of phytase and xylanase enhancing the intestinal and growth of nursery pigs and broiler chickens. There are different feed enzymes that are currently supplemented to feeds for nursery pigs and broiler chickens. Phytase and xylanase have been extensively studied showing consistent results especially related to enhancement of nutrient digestibility and growth performance of nursery pigs and broiler chickens. Findings from recent studies raise the hypothesis that phytase and xylanase could play functional roles beyond increasing nutrient digestibility, but also enhancing the intestinal health and positively modulating the intestinal microbiota of nursery pigs and broiler chickens. In conclusion, the supplementation of phytase and xylanase for nursery pigs and broiler chickens reaffirmed the benefits related to enhancement of nutrient digestibility and growth performance, whilst also playing functional roles benefiting the intestinal microbiota and reducing the intestinal oxidative damages. As a result, it could contribute to a reduction in the feed costs by allowing the use of a wider range of feedstuffs without compromising the optimal performance of the animals, as well as the environmental concerns associated with a poor hydrolysis of antinutritional factors present in the diets for swine and poultry.
这篇综述论文讨论了植酸酶和木聚糖酶在提高仔猪和肉鸡肠道功能及促进生长方面的营养和功能作用。目前,仔猪和肉鸡饲料中添加了不同的饲料酶。植酸酶和木聚糖酶已得到广泛研究,结果一致,特别是在提高仔猪和肉鸡的养分消化率和生长性能方面。近期研究结果提出了一个假设,即植酸酶和木聚糖酶可能不仅在提高养分消化率方面发挥功能作用,还能改善仔猪和肉鸡的肠道健康并积极调节其肠道微生物群。总之,在仔猪和肉鸡饲料中添加植酸酶和木聚糖酶,不仅证实了其在提高养分消化率和生长性能方面的益处,还发挥了有益于肠道微生物群和减少肠道氧化损伤的功能作用。因此,通过允许使用更广泛的饲料原料而不影响动物的最佳性能,以及减少与猪和家禽日粮中抗营养因子水解不良相关的环境问题,这有助于降低饲料成本。
