MILKING CYCLE OF Cows Milk is a source of nutrients and immunological protection for the young cow. The gestation perpd for the female cow is 9 months. Sbortly before calving, milk is secreted into the udder in preparation for the new bom. At parturition, fluid from the mammary gland known as colostrum is secreted This yellowish coloured, salty liquid has very high serum protein content and to help protect the newborn until its own immune system is established. Within 72 hours, the composition of colostrum retums to that of fresh milk, allowing to be used in the food supply. The period of lactation, or milk production, then continues for an average of 305 days, producing as much as 9000 or more kg of milk. This is quite a large amount considering the calf only needs about 1000 kg for growth
Within the lactation, the highest yield is 2-3 months yielding Within he milking lifetime, a cow reaches a in about her 40-50 Uday. kept in peak production third lactation, but can be production for lactations yield is still good. About 1-2 months after calving, the cow begins to come into heat again. She is usually inseminated ibout 3 months after calving so as to come into a yearly calving cycle. Heifers are normally fist nseminated at 15 months so she's 2 when the first calf is bom. About 60 days before the alving, the cow is dried off. There is no milking during this stage for two reasons: milk has off because of maternal needs of the fetus; udder prepare for the next mining cycle needs time to prepare for the next milking cycle-
