Entansif Süt Sığırcılığında Buzağı Hastalıkları ve Ölümlerine Bağlı Ekonomik Kayıpların Belirlenmesi.

This study aimed to determine the economic losses due to calf diseases and deaths in intensive dairy cattle. The study was conducted using data from a total of 1147 calves on a private dairy farm in Kayseri-Develi between October 2020 and October 2021. The calves examined throughout the study were divided into three different status: D1 (healthy), D2 (recovered), and D3 (death). For the death calves, additional labour, veterinarian, medicine/treatment costs, and the cost of the decreased calf are included in the calculations. While determining the price of the death calves, the calf prices determined by TİGEM according to race and gender were taken into account. In the study, it was determined that the number of sick calves was 626 (54.6%), the number of diseases (case) was 809 (70.5), and the calf mortality rate was 13.3%. It was determined that maternal age, lactation number of the cow, birth season, father (bull), calf race, and colostrum intake were effective on calf morbidity and mortality (P<0.05). In the study, it was determined that the rearing costs of healthy, sick, and death calves up to weaning were 6295.3TL ($340.2), 6508.6TL ($351.8) and 2547.3TL ($137.7), respectively. The costs of most common digestive system diseases in the study calculated between 175.4-186.5TL/case (9.5-10.1 $/case) and respiratory system diseases between 114.0-138.1TL/case (6.2-7.5 $/case). The cost of calf death due to digestive system diseases calculated 8199.0-10190.5TL ($443.2-550.8) and calf death due to respiratory system diseases calculated 7642.6-11860.1TL ($413.1-641.1). While the total cost of calf diseases was 122650.8TL/year (6629.8 $/year), the total economic losses of deaths was 1462618.8TL/year (79060.5 $/year). In dairy cattle farming, to reduce diseases and deaths in calves, is necessary to know the risk factors affecting the calf health (generally the practices of the farms, the risk factors of the cow and the calf) and to take the necessary precautions. In this study, the economic losses of calves due to disease and death in Turkish conditions were calculated and decision support was provided to make more profitable livestock production.
