摘要

目的是评价产蛋鸟类的三种住房制度,以确定Isa Brown系的动物福利和生产力参数。每个开发系统使用135只蛋鸡,分布在45只蛋鸡中;全试验期地板和笼饲系统的管理饲喂量为114gr/ d,放牧系统的管理饲喂量为14gr/ d;该研究持续了8周,其中第一周用于习惯,7周用于测试;每周结束时,收集9只鸡蛋到动物营养实验室进行研究和分析,每个笼舍系统使用3只鸡蛋。得到的信息用SPSS对每个变量进行分析。对生产、消费、饲料转化率和蛋重等参数进行了评价;其中单因素方差分析和Tukey HSD检验,差异不显著。三种笼底与放牧生产模式的产蛋率差异不显著(p值0.05),每种饲养模式的产蛋率差异为(34.54±6.93),笼底、笼底与放牧生产模式之间的转换变量差异为(1.93±0.6),蛋重差异不显著(笼底61.1 g、笼底60.8 g、放牧60.6 g)。综上所述,低巢密度的鸟类可以有更好的行为,这是一个舒适的指标,产生更高的生产力。

Productive parameters in three production models: floor, cage and grazing in layer poultry in Ocaña Norte de Santander
ABSTRACT The objective was to evaluate the three housing systems in laying birds to determine animal welfare and productivity parameters of the Isa Brown line. 135 laying hens distributed in 45 hens were used for each exploitation system; the managed feeding was 114gr/bird/day in the floor and cage systems for the entire trial period, for the grazing system 14 gr less of concentrate were used; the study had a duration of 8 weeks, of which the first was for accustoming and 7 for testing; At the end of each week, 9 eggs were collected to be studied and analyzed in the animal nutrition laboratory, using 3 eggs for each housing system. The information obtained was analyzed using SPSS for each variable. The parameters of production, consumption, feed conversion, and egg weight, were evaluated; where one-factor ANOVA and Tukey HSD test and least significant difference. The percentage production was no significant difference between the three cage floor and grazing production models being (P-Value <0.05), for the food consumption parameter there is a significant difference (P-Value> 0.05) for each housing system (34.54 ± 6.93), also happened with the conversion variable between the floor, cage production models with the grazing one (1.93 ± 0.6), for the egg weight they were similar in all housing systems (61.1 g in cage, 60.8 g in floor and 60.6 g in grazing) where there were no significant differences. In conclusion, birds with a lower housing density allow better behavior, which is an indicator of comfort, generating higher productivity.
