为分析密闭式鸡舍饲养海兰褐蛋鸡的生产效果,采用商品代海兰褐蛋鸡的周产蛋率和母鸡饲养日累计产蛋量数据,选用周产蛋率和母鸡饲养日累计产蛋量数据和海兰褐蛋鸡的产蛋标准进行对比分析。运用改进的Compartmental model对产蛋曲线进行拟合,拟合度(R~2)为0.9998,可用于预测整个产蛋期的产蛋量。运用Gompertz和Logistic两种模型对母鸡饲养日累计产蛋量增长进行拟合,拟合度(R~2)分别达到0.9988和0.997。1综合两模型的参数,其最大产蛋潜力为325.0枚,拐点周龄21.11周,拐点累积产蛋量119.56枚。结果表明,实测值、拟合值和标准值三者相当接近,说明采用“纵向通风-水帘降温”密闭式鸡舍饲养海兰褐商品代蛋鸡,将鸡舍的温度控制在23~28℃,可减少气温对海兰褐蛋鸡产蛋性能的影响,使实际产蛋率尽可能接近标准产蛋率,即使在高温季节实际产蛋率的下降幅度也较少,从而达到生产效益最大化。
In order to analyze the production effect of Highland hen hen in closed house, the weekly egg production rate of henry hen and the cumulative egg production of hen day were used. The weekly egg production rate and hen day The data of total egg production and the laying standard of Hy-line hen were compared. The improved Compartmental model was used to fit the egg production curve. The fitting degree (R ~ 2) was 0.9998, which could be used to predict the egg production during the whole laying period. Gompertz and Logistic models were used to fit the cumulative growth of egg production on the day of hen feeding. The fitting degree (R ~ 2) reached 0.9988 and 0.997.1 respectively, and the maximum egg laying potential was 325.0 , Inflection point age 21.11 weeks, inflection point cumulative egg production 119.56 pieces. The results show that the measured values, the fitted values and the standard values are very close to each other, indicating the use of “vertical ventilation - curtain cooling ” closed henry breeding hens brown hens, the chicken coop temperature control at 23 ~ 28 ℃, can reduce the impact of temperature on the laying hen brown egg laying performance, the actual egg production rate as close as possible to the standard egg production rate, even in the hot season, the actual rate of decline in egg production is also less, so as to achieve production Maximize benefits.
