Alternative strategies in protein nutrition of dairy cattle: can we avoid excesses and deficiencies?
The role of dietary protein in the nutrition of the dairy cow and overall farm sustainability can be summarized as: (1) effects on dry matter intake (DMI), milk yield, and milk composition, (2) effects on feed costs, (3) environmental effects, and (4) possible effects on reproduction efficiency. Historically protein has been fed trying to satisfy requirements in term of CP, both in percentage of D.M. or grams per cow per day, and more recently we passed to the concept of metabolizable protein and amminoacids. Basically when we are feeding cows we have to be aware that we are feeding a portion of protein available for the microorganism in the rumen (RDP) and a portion of amminoacids that will by-pass the rumen and will be absorbed in the gut (RUP). The balance between this two fractions is crucial in maximizing cow’s performance. Thus the two questions we have to ask our self when balancing diets in terms of protein are: are we providing the proper RDP to maximize microbial protein production in the rumen? Are we feeding enough amminoacids to maximize milk and protein production?
To harvest the high quality forages in Ukraine — is possible. This was proved by LLC «Vitchyzna», which is in Sumy region. According to the results of the contest for the best alfalfa silo in 2016, this farm won the first place.
The guest of honor of the Xth International Dairy Congress was Heinz Pöttinger, managing co-founder of PÖTTINGER Landtechnik GmbH (Austria), which is one of the world leaders in the production of tillage machines and forage harvesters.
Effective reproduction of the herd on modern industrial dairy farms is impossible without a high-quality program, which can help to identify cows in heat. Since the visual definition presents a certain complexity, specialists try practice other methods of heat detection.
The season of big milk came to Ukraine this year much earlier than always — at the end of January. So processors decided to begin to decrease purchase prices. The farmer gets less and less, but consumers should pay same money. In case with cheese and butter — even more.
In previous issues we talked about various aspects of the automated feeding systems for calves. In particular, we describe the foreign experience. Although the use of automatic feeders — a rare practice at the domestic dairy farms, there are several farms where calves are fed with the help of machines.
Vadim Chagarovsky, Chairman of the board of the Union of Ukrainian dairy enterprises — is a specialist who started his professional as foreman assistant at the dairy plant, and gradually passed all stages up to high positions in the dairy industry in Ukraine.
Elman Orujov is well known in the circle of Ukrainian milk producers and beyond it. He was among the first who has began to introduce in Ukraine the industrial production of milk. Over the past ten years, the industry has reached a new level, but the world’s best performance is yet to come.
