Bovine Viral Diarrhea in cattle herds is one of the most common diseases on dairy farms in the whole world, including Ukraine. This disease can result in major economic loss. It’s impossible to get rid of the problem completely, but there is a number of measures which help to reduce the incidence of animals and at the same time save money. We offer our readers a systematic approach to solving this problem — from analysis of the causes of the disease to measures to combat the virus.

Systems which maintain the microclimate in barns is one of the most economically sound investments. Equipment for ventilation and air cooling allows to obtain permanent milk yield not only in summer but in the fall, as heat stress effects milk production during a long period.

Many dairy farms in Ukraine have turned away from tie-stall housing system or gradually changing to loose housing system. The latter occurs mainly in two forms: keeping cows in deep-bedded units or free stalls. Under these conditions cows are easy to move inside the barn and in a pasture. It improves their health and makes it possible to increase the mechanization of production processes in the barn, such as: milking, cleaning, distribution of feed. Energy costs are reduced significantly together with labor costs, and animals feel better.

When choosing corn hybrids modern farmers are paying more attention to their purpose: planting for grain or silage etc. How to choose hybrids best suited to a farm operation? What traits of hybrids should be considered? How will our choice affect profitability in general? We will try to answer these questions.
Well-fed cattle give a lot of milk. That’s the reason why dairy producers pay so much attention to cows’ diets and balancing of ration ingredients. Forages take their rightfull place here, especially corn silage. Many trials on how the kernel breakage influences nutrition and digestibility of silage have been conducted for many years. Today no one doubts that we need to do it. Researchers have also observed the stover particle length. As a result, shredlage was invented. Nowadays it is generating a lot of interest among dairy and livestock producers and their nutritionists in Ukraine as well as abroad. Let’s acquaint with a new method closer.

By-products of the food industry are used for cattle feeding to cut the cost of cattle diets and to increase their nutritional value. Some of these products are the source of non-digestible protein. The others might be used instead of forage. Using them we may increase fiber level in feeds. Considering a unique nutrient content of food industry by-products, especially brewer’s grains, they are used as ingredients for the balanced ration.

High-producing dairy cows are rather capricious to nutritive feeding, in particular they need to get required energy. Energy supply is of great importance at the end of dry period and in early lactation. First months after calving will determine the profitability of production.

A lot of scientists have proved: the use of the best bull’s semen isn’t the primary prerequisite of the success. If animals with the best genetics are bred under the condition where production procedures are ignored, the potential of the genotype won’t realize. Besides, practice shows that following all the production requirements, even in case of not high-yielding cows, gives high production indices. Nowadays cattle breeders inseminate cows using semen of American or Canadian beef sires. In addition to that ‘a detail’ is left: to learn how to rear potentially high-yielding cows properly.

Ketosis in dairy cows is a disease characterized by impaired carbohydrate, fat, protein, energy and mineral metabolism. It is accompanied by accumulation of ketone bodies in the animal’s body, degenerative changes in the liver, heart, kidney, ovary, thyroid and parathyroid glands and pituitary adrenal system, which causes big losses. How to diagnose the problem and how to act in order to prevent disease or alleviate it? Read more about in the article.

Protein components in a dairy cattle diet is the most expensive compared to all others. The purchase of forage rich in protein (such as soy bean meal or fodder yeast) takes the biggest share of the cost. That’s why farm owners are interested in replacing these ingredients with cheaper ones, which do not adversely affect the physiology of animals. An advantageous alternative to expensive protein components of the diet are rape by-products, including cattle cakes.
