全程饲喂配合料肉仔鹅上市屠宰日龄的研究

研究冬季无牧草条件下肉仔鹅全程饲喂配合料的上市屠宰日龄及提早上市屠宰的影响因素。8、9、10周龄肉仔鹅每千克体重饲料成本呈极显著增加，以最低饲料成本衡量适宜屠宰日龄时．56日龄上市屠宰最佳；8、9、10周龄肉仔鹩胸部肌肉和翅膀仍显著或极显著地增长，以胸部肌肉和翅膀最大产肉量衡量屠宰日龄时．需要70日龄才适宜上市屠宰；以主翼羽根干血（泛白）衡量适宜屠宰日龄时．需要70日龄或超过70日龄才能上市屠宰。结论：全程饲喂配合饲料可使肉鹩提前达到上市体重．影响肉仔鹩提早上市屠宰的主要因素是胸部和翅膀产肉量和羽毛生长缓慢。结果提示．选育胸部肌肉、翅膀、羽毛早期快速生长的品系，是饲养内仔鹩提早到8周龄上市屠宰的先决条件。
