Amino acid nutrition and reproduction

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.

Prepartum and postpartum nutritional management for optimal fertility in high-yielding dairy cows

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.

The calf on the bedding — the milk in the tank

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.

Three enemies of feed making

Yuri Sivov, Director of Development of CC ADP

Roughage always was the basis of the cows’ ration: green grass mass, hay, haylage, silage. The cost of poor and quality feed is the same or slightly different. But the effectiveness of their use is better for quality feed.

Non-protein nitrogen. What is it? With what is it eaten? What is withheld when they sell?

In contrast to the single-chamber stomach animals, animals with multi-chamber stomach (actually, it is about cows) in the mesh of the fissile stomach protein products can replace the production of large-scale chemistry.

Perfect milker

Prepared on the basis of a presentation by representatives of «DeLaval» Edward Ziegert at the opening of a dairy complex PAL «Ukraine» (HC «Eridon») in the village Pochuyky Popilnyansky district, Zhytomyr region.
