【摘要】：母猪妊娠后期是母猪乳腺及胎猪快速发育的重要时期,为处于这一时期的母猪配制营养水平适宜的日粮对提高母猪繁殖效率尤为重要。妊娠后期母猪乳腺发育及胎猪的生长对能量、蛋白质及氨基酸的需求不同,如何给妊娠母猪提供合理的营养,在满足胎猪生长发育的同时满足乳腺发育的需要研究还比较少。作者主要介绍了母猪妊娠后期日粮中的能量、蛋白质及氨基酸水平对乳腺发育及胎猪生长的影响,同时提出母猪妊娠后期能量、蛋白质及氨基酸的需要量及合理比例,以期为养猪生产者提供参考。
[Abstract]:The second trimester of sows is an important period for the rapid development of sows' mammary glands and foetus. It is very important for sows in this period to prepare diets with suitable nutritional level to improve the reproductive efficiency of sows. The development of mammary gland and the growth of foetus in late pregnancy have different demands on energy, protein and amino acid. There are few studies on how to provide reasonable nutrition for pregnant sows and meet the needs of breast development while meeting the growth and development of fetal pigs. The authors mainly introduce the energy in the diets of sows in the later stage of pregnancy. The effects of protein and amino acid levels on mammary gland development and fetal pig growth were also discussed. The energy, protein and amino acid requirements of sows in late pregnancy and their reasonable proportion were proposed in order to provide reference for pig producers.
