Abstract

This study aimed to evaluate the association of factors such as nutrition, thermal humidity index (THI), age, and lactation period with the occurrence of repeat breeding of dairy cows. The sample consisted of Holstein Friesian cows aged 1-11 years, with lactation periods ranging from 1 to 7 months, currently in lactation, and experiencing repeat breeding (inseminated three or more times without conception, despite exhibiting normal estrous cycles and intervals). The results showed that feeding practices by farmers did not significantly differ (p >0.05) in relation to the incidence of repeat breeding. THI values recorded in several barns also showed no significant differences (p >0.05), with the cows experiencing light to moderate heat stress. Similarly, the frequency of artificial insemination and the estrous cycle intervals remained within the normal range. The highest incidence of repeat breeding was observed in cows aged 2.5 to 5.5 years, accounting for 78.13%, and during lactation periods of 1-3 months, accounting for 81.26%. It can be concluded that there were no significant differences in the provision of forage and leguminous feed between normal cows and those with repeat breeding, and the crude protein content of forage did not influence its occurrence. Additionally, there was no indirect relationship between THI and repeat breeding. However, the incidence of repeat breeding tended to increase in cows aged 3-4 years, and during the second and third lactation periods.

Abstract

This study aimed to determine the relationship between total protein, albumin, and globulin in the blood with the incidence of repeat breeders in dairy cows. Ten normal cyclic cows and ten repeat breeders cows were taken randomly based on the reproductive records of the Tani Wilis Village Cooperative, Sendang District, Tulungagung Regency. Questionnaire data in the form of farmers' knowledge about dairy cows' reproductive systems and feed treatment is displayed descriptively.  Dairy cows blood samples were taken from the jugular vein 6 mL to measure total protein, albumin, and globulin levels. Data analyzed using the Statistical Product and Service Solution software at a significance level of 5%. The results showed that the total protein, albumin, and globulin levels in normal dairy cows and dairy cows with repeat breeders were not significantly different (p>0.05). However, in normal cyclic cows, most of the total protein, albumin, and globulin levels (80-100% of normal cyclic cows samples) are within the normal range. Meanwhile, the majority of repeat breeder cows (60-70% of the repeat breeder cows) had total protein, albumin, and globulin levels lower than the normal range (p<0.05). It could be concluded that there was a relationship between the incidence of repeat breeder and total protein, albumin, and globulin levels in the blood serum of dairy cows with repeat breeder. Therefore, it is suggested to raise awareness of smallholder farmers about proper feeding and feeding management to reduce repeat breeder cases.
