Abstract

FIELD: food industry.

SUBSTANCE: invention relates to breeding, in particular, to a method for functional feeding of sows and piglets. The method for functional feeding of sows and piglets envisages usage of a lactic acid additive in the basic animal ration. The lactic acid fodder additive is administered to sows during the whole pregnant period in an amount of 0.1 ml/kg of live weight daily; the lactic acid additive is administered to piglets in an amount of 0.2 ml/kg of live weight at an age of 14 - 35 days daily. The lactic acid fodder additive is represented by a complex of lactic acid bacteria improving animal digestion function and increasing immunity.

EFFECT: said invention usage will allow to enhance animals immunity as well as to preserve livestock, increase piglets size at birth and live-weight.

Description

The invention relates to animal husbandry, in particular to the feeding of farm animals.

Pigs are characterized by high multiple fertility, short embryonic developmental period, early maturity and high lethal yield. This allows you to receive products from them with the economical use of feed and labor.

Large-fruited animals attach great importance in the practice of pig farming.

A known method of feeding piglets, including the introduction into the main diet of barley, corn, wheat, premix in the amount of 0.9-1.5% of the main diet for piglets aged 21-60 days (RU 2083131 "Method of feeding piglets", A23K 00, A23K 1/16). Premix contains the necessary vitamins, minerals, antibacterial drug - Biovit. The disadvantage of this method is the multicomponent diet used, in addition, in piglets at the age of 21-60 days, functional immaturity of the digestive apparatus is established, which does not allow the full use of the nutrients of crops included in the main diet. In suckling pigs, there is no hydrochloric acid in the gastric juice for 3 weeks after birth. As a result, the pepsinogen present in the gastric juice does not turn into pepsin, which is necessary for the hydrolysis of plant-based proteins. In addition, due to the low activity of enzymes: amylase, maltase and sucrose, starch, glucose and sucrose are almost not absorbed in piglets, i.e. carbohydrate part of vegetable feed (Pig breeder's guide. Bazhov G.M., Bakhireva L.A., Bakhova A.G. St. Petersburg, 2007. - 272 p.). The introduction of a lactic acid supplement (MCD) optimizes the digestion process in suckling pigs and eliminates the indicated digestion problems in them.

A known method of growing piglets (application No. 93033490/15 "Method of growing piglets", A23K 1/17). The essence of the method is to use in feeding piglets the probiotic Lactobacillus amylovorus, which is a natural inhabitant of the gastrointestinal tract of healthy pigs, in an amount of 1-3 ml per head, depending on the live weight of the animal. The disadvantage of this method is that this probiotic is used only for medicinal purposes. In the proposed method, MKD is used as a necessary component of the diet.

The essence of the invention lies in the fact that the main diet of sows includes a lactic acid feed additive (MKD), which is a complex of lactic acid bacteria (propionic acid bacteria, lactic acid bacteria, lactic acid streptococcus), at the rate of 0.1 ml / kg of live weight of sows for the entire pregnant period. From 14 days until the weaning from sows at 35 days of age, MKD of 0.2 ml / kg body weight per day is also introduced into the feed mixture.

An object of the invention is to improve the reproductive ability of sows, improve digestion, increase immunity, vitality and large fertility of the resulting offspring.

The invention is illustrated by the following examples.

For the experiment, 2 groups of Landras sows of the same breed of the third farrow were selected. Group 1 in the amount of 5 goals, receiving the main diet, served as a control. The diet of 2 groups (5 goals) included MCD of 0.1 ml / kg body weight for the entire pregnant period. In the process of the experiment took into account:

- the safety of sows and the resulting offspring when grown;

- consumption of lactic feed additives;

- the number and live weight of newborn piglets.

The results are presented in table 1.

The average live weight of piglets in the experimental groups was 56.8% higher than in the control group and amounted to 1491 and 951 respectively. The total mass of business newborn piglets (up to 600 g) from one sow in the experimental group was 17.3 kg , while in the control - 10.5 kg, i.e. 64.8% more.

Piglets of both groups from 14 days of age and before weaning from sows at 35 days of age were fed with specially prepared feeds. An MKD of 0.2 ml / kg body weight per day was added to the feed of the experimental group. Thus, during the suction period, the piglets received 26 ml of MCD, the sows of the experimental group continued to feed MCD until weaning of the piglets at 0.1 ml / kg of live weight per day.

During the suction period, the gain in live weight of each pig in the experimental group was 9572 g, while in the control group it was 7607 g, which is 25.8% more. The average daily increase in the experimental and control groups was 273.5 and 217.3 g, respectively.

The result of the invention is an increase in large-fruited by 56.8%, an increase in the gain in live weight of piglets from 14 days of age to weaning at the age of 35 days in 1965.
