摘要
乳鸽出壳后依赖于亲鸽鸽乳的哺育,严重限制母鸽产雏数,制约鸽业发展。文中基于前人对乳鸽生长发育特点的研究,通过测定鸽乳中的氨基酸组成和含量,分析出壳后乳鸽早期小肠氨基酸转运载体的时空表达规律,揭示乳鸽肠道氨基酸转运的分子机制。在此基础上,采用胚蛋给养的技术方法,探讨碱性氨基酸对乳鸽早期生长发育的营养调控作用。
during the immediately post-hatch period,young pigeons( squabs) grow depend on the crop milk from parental pigeon,which severely limits the production of the female pigeon,and restricts the development of pigeon industry. Based on the previous studies on the growth development characteristics of squab,this article revealed the molecular mechanism of amino acid transport in the intestine by determining the amino acid composition and content in crop milk and analyzing the temporal and spatial expression of amino acid transporters in small intestine of squabs during the early post-hatch period. Furthermore,in ovo injection was adopted to explore the nutritional manipulation of basic amino acids on early growth development of squab.
