Feeding calves is one of the key components in the technology of cattle breeding and require considerable attention. For a long time on minimizing costs by reducing milk portions with the aim to speed up the transition of animals to dry and concentrated feed was laid a special attention.
Today, plant breeders can offer a wide range of silage hybrids to milk producers. About their technological and economic advantages, especially the selection and implementation of high genetic potential, tells Benoit Delord, head of the "Animal Feeding" company Limagrain.

Most of the health problems and the related veterinary costs are incurred within the first thirty days of lactation. Management and feeding during the dry period may influence the occurrence of disease at the time of calving. Along with such metabolic disorders as hypocalcemia, acidosis and ketosis in cows may occur abomasum displacement.
Today the market of feed additives is very diversified and characterized by a high level of competition. Sometimes it is not enough just to offer good products. Agricultural producers hope to get additional value from the cooperation in the form of services, advice and other things, while the product itself becomes only one of the instruments of the general program solutions.
In a previous article we examined the causes and predisposing factors of the spread of mastitis in cows («Milk and Farm», № 1, February 2016). Violation of the veterinary and sanitary standards of housing and milking technologies underlie occurrence of mastitis, and the absence of timely diagnosis, isolation of sick animals and their treatment leads to the spread of the disease. Total economic measures aimed at reducing the incidence rate of cows with mastitis should include three main strategies:
The ideal reproduction in high-performance herd is considered as follows: the service period — up to 85 days, conception rate after the first artificial insemination — more than 50%, conception rate — less than 1.7, and the duration of calving interval — not less than 390 days. Achieving these objectives is quite difficult due to a number of different factors. One of the conditions of survival of embryos and successful course of pregnancy is considered in the content of amino acids in the diet of dairy cows. About the results of various studies of this issue during the Eastern European Dairy Congress told the doctor of veterinary medicine, lecturer at the University of Illinois Phil Cardoso.
What is expected from the fresh cows? A healthy calf, a good feed intake and high productivity, and at least five lactations. But transition period which is very important is not usually mentioned. What should be done to minimize health problems now and in the future to get the maximum production, and good reproductive performance, on the Eastern European Dairy Congress told Phil Cardos, the doctor of veterinary medicine, lecturer at the University of Illinois.
As promised, one more piece of information from Lindel Whitelock, and this time about reproduction program on the dairy farm «Larson Acres» (Evansville, Wisconsin). Thanks to this program they have high productivity and a sufficient number of calves to repair their own herds and for sale.
In Ukraine the relation to growing calves of dairy breeds for meat is unambiguous. Yet a lot of farms fatten them. We decided to talk about the North American experience of keeping and fattening animals in this category.
