Disclosed is a method for converting phenylalanyl to tyrosyl residues in casein by hydroxylation (OH) and for reacting diiodotyrosine with casein to get higher thyroxine yields the thyroactive iodination of casein. A method is disclosed for elevating blood thyroid hormone levels in avian species (especially poultry species such as chickens, turkeys, ducks, quail, etc.) and other animals (e.g., mammals) by implantation, injection, or dietary (feed or water) supplementation with thyroid hormones or thyroid-active substances (e.g., L-thyroxine, triiodothyronine, defatted and dessicated thyroid, or rendered animal byproduct meal with substantial thyroid tissue), optionally in combination with other substances which improve or give additional responses, to achieve a number of economically important productive performance benefits. Manipulating thyroid hormone levels at a sensitive critical period in males to induce transient hypothyroidism results in subsequent increased testes size and sperm production. Thyroid hormones are added to fresh or diluted semen, optionally with other enhancers, to improve sperm characteristics.
公开了一种通过羟基化(OH)将酪蛋白中的苯丙氨酰转化为酪基残基的方法,以及将二碘酪氨酸与酪蛋白反应以获得更高的甲状腺素产量的酪蛋白甲状腺活性碘化方法。本发明公开了一种方法,通过植入、注射或饮食(饲料或水)补充甲状腺激素或甲状腺活性物质(如:L-甲状腺素、三碘甲状腺素等)来提高禽类(特别是鸡、火鸡、鸭、鹌鹑等家禽)和其他动物(如哺乳动物)血液中的甲状腺激素水平、L-甲状腺素、三碘甲状腺原氨酸、脱脂和去壳甲状腺或含有大量甲状腺组织的动物副产品粉),可选择与其他物质结合使用,以改善或提供额外的反应,从而实现一系列具有重要经济意义的生产性能效益。在雄性牲畜敏感的关键时期操纵甲状腺激素水平,诱发短暂的甲状腺功能减退,从而使睾丸增大,精子产量增加。在新鲜精液或稀释精液中添加甲状腺激素,也可选择添加其他增强剂,以改善精子特性。
