The aim was to assess the efficacy of pine leaves as an alternative bedding material on the performance of broiler chicks.
The present study was conducted in summer. Total 120, day old Vencobb straight run chicks were procured, and after 5 days of brooding, chicks were randomly distributed into four treatment groups viz. paddy husk (Group I), paddy straw (Group II), pine leaves (Group III), and combination of paddy straw and pine leaves (Group IV), each having 30 chicks with 3 replicates of 10 chicks each. Chicks were reared under intensive conditions in houses that have a semi-controlled environment, with optimum temperature and adequate ventilation. Food and water were provided as per NRC (1994) requirement.
The average body weight after 6 weeks of the experiment was 2018.83±31.11, 1983.80±33.27, 2007.36±35.73, and 1938.43±36.35 g. The bedding type had no significant effect on the carcass characteristics viz. evisceration rate and proportion of cut-up parts of the carcass except giblet yield. The experiment suggested that performance of broiler chicks reared on paddy straw and pine leaves as litter material, had improved body weight and feed conversion ratio as compared to rearing on paddy husk as bedding material. Bacterial count, parasitic load and the N, P, K value of manure of different bedding material shows no significant difference.
Pine leaves have a potential to be used as an alternative source of litter material to economize poultry production in a sustainable way, so as to make poultry farming as a profitable entrepreneur.
评估松叶作为替代垫料对肉鸡生长性能的影响。
本研究在夏季进行。共采购120只1日龄的Vencobb直选雏鸡,育雏5天后,将雏鸡随机分为四个处理组,即稻壳组(第一组)、稻草组(第二组)、松叶组(第三组)以及稻草和松叶混合组(第四组),每组30只雏鸡,每组再分为3个重复,每个重复10只雏鸡。雏鸡在具有半控制环境、温度适宜且通风良好的鸡舍中进行集约化饲养。按照美国国家研究委员会(1994年)的要求提供食物和水。
实验6周后的平均体重分别为2018.83±31.11、1983.80±33.27、2007.36±35.73和1938.43±36.35克。垫料类型对胴体特性(即去内脏率和胴体切块比例,除内脏产量外)没有显著影响。实验表明,与以稻壳为垫料饲养相比,以稻草和松叶为垫料饲养的肉鸡体重和饲料转化率有所提高。不同垫料的粪便细菌计数、寄生虫负荷以及氮、磷、钾值均无显著差异。
松叶有潜力作为替代垫料来源,以可持续的方式节约家禽生产成本,从而使家禽养殖成为一项有利可图的事业。
