Evaluation of milk production and reproductive performance of Holstein dairy cows using multi-component binder in feed. Animal Nutrition and Feed Technology, 23: 185–193. The mycotoxins in animal feed have caused various problems for farmers. The present study determined the effect of multi-component binder (MCB) on milk production and reproductive performance in Holstein dairy cows. This study was 84 days long and 60 lactating cows kept at dairy farm were chosen for the experiment. Cows were classified into two groups: control group (N= 30) were without MCB and the treatment group (N= 30) received the MCB in their diet. For first 10 days no binders were added to diet. For the next 74 days binders were added to total mixed ration (TMR), and then milk samples were taken on the 17th, 34th, 57th, 77th, and 84th day. Furthermore, the reproductive indices (service/conception, uterine infection, calving interval, open days, uterine involution, and ovarian cysts) were diagnosed the farm veterinarian. The results indicated that the production of milk and sum of protein in it has increased while milk fat, lactose, somatic cell count (SCC), and AFM1 has decreased with increasing consume days of MCB in the diet. Furthermore, using the MCB showed no negative effect on reproduction indices. Ovarian cysts were reduced to zero with MCB diet. In current study, the quality of milk as well as reproduction indices were improved by using MCB in the diet which may reduce future risks such as retained placental, dystocia and uterine infections in animals.
