Effects of Different Feeding Methods and Welfare Management Measures on the Growth and Development of Guanling Cattle
In order to study the effects of different feeding methods and welfare management measures on the weight gain,growth and health status of Guanling cattle under barn feeding condition,30 Guanling cattle cows were randomly divided into 5 groups using a group experimental design method.The 5 groups were named as floor teth-ered breeding,which was taken as the control group,floor free-range breeding as the experimental group 1,floor free-range breeding+cattle body brush as the experimental group 2,fermentation bed free-range breeding as the experimental group 3,fermentation bed free-range breeding+cattle body brush as the experimental group 4.Each group contained 6 cows.The trial period was 120 days,and different feeding methods were compared between tethered breeding and free-range breeding.The results showed that under the barn feeding condition,the fermen-tation bed free-range and the installation of cattle body brushes were the most beneficial to the weight gain of Guanling cattle.The average daily weight gain during the whole period was 44.68％higher than that of floor teth-ered feeding and floor free-range,which was significantly higher than that of experimental group 2 and experimen-tal group 3(P＜0.05).The body height and body oblique length of experimental group 4 got the largest increase,and the body height had significantly higher increase than that of other treatment groups.The increase of body ob-lique length was significantly higher than that of experimental group 1 and experimental group 3(P＜0.05).At the same time,the fermentation bed and the installation of cattle brushes have improved animal welfare,ensured the health of cattle,and improved the feeding environment.In the case of free-range fermentation bed and installation of cattle brush,the overall feeding effect of Guanling cattle was the most favorable,which not only improved the breeding efficiency and health level,but also guaranteed the welfare of cattle and animals,and effectively avoiding environmental pollution.
