RU2301523C1 - Method for compensating selenium deficiency in the body of lactating cows - Google Patents

Abstract

FIELD: animal science.

SUBSTANCE: it is necessary to introduce biologically active additives "Gorasel" or "Tykvorsel" being selenopyrane solutions in the mixture of vegetable oils. These biologically active additives should be injected subcutaneously per 10 ml/cow 4 times: the first time - immediately afterlaunching, and then 30, 20 and 10 d before calving. The innovation suggested enables to increase milk yield and milk quality.

EFFECT: higher efficiency.

Description

The invention relates to animal husbandry, specifically to methods for improving the quality of milk.

Lack of selenium in the body of cows significantly affects their health and productive qualities. This microelement is an irreplaceable biologically active substance contained in all organs and tissues, has an antioxidant effect, stimulates the growth and development of the body, participates in the interaction of proteins, enzymes, is part of amino acids, and is involved in protein synthesis. To maintain normal metabolism and the prevention of diseases associated with a deficiency of selenium, it is necessary to regularly enter the body.

There is a method of improving the quality of milk by using in the diet of the selenorganic preparation DAFS-25, the basis of which is diacetophenonyl selenide based on the introduction of lactating cows of selenium at a dose of 1.6 mg per 1 kg of dry diet [1]. The DAFS-25 preparation contains 22.5% selenium and allows you to activate metabolic processes in the animal organism and reduce the possibility of selenium deficiency and other diseases [2]. When using it for 180 days of lactation, the average daily milk yield of cows increased by 6.3%, the quality of milk increased:

4.5% fat content

0.6% protein

milk sugar by 0.2%,

SOMO 1.0%

the duration of rennet coagulation decreased by 17.7% relative to the control.

The disadvantages of the method: a limited increase in indicators of milk yield and milk quality, a low level of reduction in the duration of rennet coagulation of milk.

It is known to use a selenium-containing preparation of bis (benzoylmethyl) selenide as a means for the treatment and prevention of various diseases of farm animals in order to increase their productivity by intramuscular administration [3] (prototype).

The technical result is an increase in the productivity and quality of milk.

This is achieved by the fact that, as a selenium-containing preparation, the Gorasel biologically active additives (BAA) containing a solution of selenopyran (10 mg / kg in selenium) in a mixture of mustard and milk thistle vegetable oils (1: 1 ratio), or Tykvorsel are used. containing a solution of selenopyran (10 mg / kg selenium) in a mixture of pumpkin and milk thistle oil (1: 1 ratio), in the form of injections. The drug is injected subcutaneously at 10 ml per head 4 times in the prepopular fold for the first time immediately after launch, and then 30, 20 and 10 days before calving. These dietary supplements are developed by GU VNITI MMS and PPS. BAA "Gorasel" according to TU 9141-094-10514645-04, certificate of state registration No. 77.99.23.3.U.6624.12.04. dated December 1, 2004 and the Tykvorsel dietary supplement according to TU 9141-086-10514645-04, state registration certificate No. 77.99.23.3. У.6801.12.04 dated December 2, 2004 - they are a reddish-brown oily liquid.

The preparations were tested in the Luch breeding farm in the Gorodishchensky district of the Volgograd region for breeding black-motley cattle. To conduct the experiment on the basis of the steam-analog principle, 3 groups of lactating cows were formed (25 animals each): control group, experimental groups I and II. Animals of all groups received a general economic ration (OR), in the first experimental group, the animals were injected subcutaneously with the Gorasel drug at a dose of 10 ml per head 4 times into the prepopulation fold immediately after launch, and then 30, 20 and 10 days before the animals. calving. For animals of the II experimental group - the drug Tykvorsel in the same way as animals of the I experimental group. The duration of the experiment (main period) is 180 days. During the experimental period, monthly milk was analyzed according to the main indicators, as well as milk yield. Improving the quality of milk was observed throughout the experiment. The results of the experiment after (180 days) are shown in the table.

Milking and quality indicators Groups Control I II milk yield, kg 14.00 15.90 17.40 fat kg 3.92 4.11 4.28 protein,% 3.21 3.38 3.45 milk sugar,% 4.70 4.93 5.01 SOMO,% 8.70 9.17 9.36 rennet coagulation, min 42,4 32.8 31.7

As can be seen from the table, in the proposed method using "Gorasel" and "Tykvorsela" in comparison with the control:

- milk yield increased by 13.6% and 24.3%, respectively, against 6.3% in the prototype;

- increased content:

4.8% and 9.2% fat against 4.5%,

protein by 5.3% and 7.5% against 0.6%,

4.9% and 6.6% milk sugar versus 0.2%,

SOMO by 5.4% and 7.6% versus 1.0%, respectively;

- the duration of rennet coagulation decreased by 29.3% and 33.8% compared to 17.7%.

Thus, the proposed method allowed to increase the milk yield and quality of milk, as well as its cheese suitability.
