Abstract

The invention relates to agriculture, in particular to fodder production. The purpose of the invention is to increase the productivity of animals during the spring transition period. For this, in the spring transitional period, in addition to the spring unstable nutritionally herbage, the feedstuff is fed with a feed additive containing,%: powdered sulphate lignin 30.0-40.0

phosphorus free phosphate 1.9-2.1, salt 1.4-1.6

Description

The invention relates to agriculture, in particular to fodder production.

The aim of the invention is to increase the productivity of animals during the spring transition period.

PRI me R 1. Powdered sulfate lignin was obtained by industrial sulfuric acid method with drying in a spray dryer at 300 ° C at the exit. Characterized by the following physicochemical properties; acid reaction (pH 1.9) humidity 33.1%, ash content 3.5, composition,%: carbon 42.9. nitrogen 0.34, phosphorus (PaOb) 0.02, potassium (K20) 0.02, calcium (CaO) 0.20, sulfur (50z) 0.41, Particle size 0.3 cm. Dry mass of powdered sulphate lignin was very reactive It is highly dispersed, non-toxic and able to hydrate intensively (100 parts by weight absorbs 690 parts of water, which is 2.3 times higher than straw). Functional phenol-hydroxyl (4.1 mg-eq / g), carboxyl (11 2 mg-eq / g) groups prevailed in it.

Powdered sulphate lignin is mixed with defluorinated phosphate, sodium chloride, magnesium sulphate, corn starch, fodder animal fat, and barley grits.

A herd of black-and-white cows was divided into four groups: the control and three experienced Cows in the control group in addition to grazing grass in spring

The lower transition period received a base transition feed mixture (PCB) (according to the prototype), and the proposed feed mixture (PCS) was tested in the ratios of the components listed in Table 1. The time of continuous feeding ZKS was 35 days. The composition and nutritional value of PKS and ZKS are presented in table 1.

Before the beginning of spring feeding in animals of all groups, the physiological state, nature of digestion and milk yield were the same. By the end of the transition period, cows eating a new feed additive (1, II, III experimental groups) had a preferable rumen content for sibiotic bacteria. . Ammonia nitrogen was utilized by 11.8-31.8% more intensively, which confirms the positive effect of powdered sulfate lignin on this process (Table 2),

Optimization of spring ration contributed to a significant increase in milk production by 5.6-10.6% (, 95 and PX), 99) and an increase in milk fat content by 0.23-0.39%. The income per centner of milk products for cows of experimental groups was 3.75-6.35 rubles.

EXAMPLE 2. Three groups of 12 month old gobies, analogous to the miner Simmental breed, were formed. During the transition from stables to pasture ration, bulls of group I (control) were prepared using known transition fodder mixture (PKS), and in groups II and 111, they were adjusted based on the new ZKS with the lower (II group), upper (III group) set of components (table 3).

The use of a feed additive containing powdered sulphate lignin had a positive effect on digestion, meat productivity of gobies and the cost of their gains. The bulls of the I and III groups did not have cases of swelling of the rumen, digestive disorders. By the end of the spring transitional period, their weight was reliably (P 0.95; P 0.99) higher by 21–28 kg (5.0 and 6.7%) with a lower cost (8.18–8.89 rub).

The proposed feed additive allows one to more fully eliminate the drawbacks of the spring transitional ration and has a positive effect on the dairy, meat productivity of cattle. The feed additive t with powdered sulphate lignin permanently stimulates salivation in animals, and with its large absorption and water-absorbing ability optimizes the moisture content of the unstable spring diet. The additive also provides for the binding of excessively released cicatricial ammonia to polar functional groups (phenolic, carboxyl, etc.) by reaction;

environment in the zone of action of large industrial plants. They have a real opportunity to switch to low-waste mode of work, and on this basis to combine their production activity with the agro-industrial complex.

It is impractical to include a distinctive component in the feed additive of more than 40% to the mass content because of a possible reduction in the digestibility of the basic dietary nutrients. Feeding powdered sulphate lignin as part of an additive of less than 30% does not eliminate the imbalance of the transitional diet.
