物联网介导的自动饲喂模式对西门塔尔牛产奶性能的影响
Effect of IoT-mediated Automatic Feeding Mode on Milk Production Performance of Simmental Cattle
摘要
Abstract
This experiment aims to investigate the impact of an Internet of Things(IoT)mediated au-tomatic feeding model on the milk production performance of lactating cows.A total of 180 healthy lacta-ting Simmental cows with similar body conditions and close parity(1-2 parities)were selected for the study.Based on different feeding models,the cows were randomly divided into an experimental group(au-tomatic feeding)and a control group(manual feeding).According to their daily milk production,the cows were categorized into high-yield(21±2.9 kg/d),medium-yield(13±0.9 kg/d),and low-yield(8±0.9 kg/d)groups,with 30 cows in each category and each cow representing one replicate.The pre-feeding period lasted for 15 days,followed by a formal experimental period of 30 days.The results indicated that the IoT-mediated automatic feeding model significantly increased the daily milk production of high-yield lactating cows(P＜0.05),but had no significant effect on the daily milk production and milk quality of medium-and low-yield cows(P＞0.05).The automatic feeding model also resulted in a significant reduction in feed con-sumption and leftover feed(P＜0.01).The overall cost accounting for the experimental group showed a significant decrease compared to the control group(P＜0.01),while milk production profitability signifi-cantly increased(P＜0.01).Additionally,the experimental group utilizing the automatic feeding model saved an average of 32.21 yuan per day in comprehensive costs,amounting to an annual savings of 11756.65 yuan.Daily milk production revenue increased by 117.88 yuan,leading to an annual revenue in-crease of 43026.2 yuan.The results suggest that the IoT-mediated automatic feeding model can enhance milk production in high-yield lactating cows,reduce production costs for farms,and increase economic benefits.关键词
