Abstract

Usage: in feed production. Essence: the use of waste products of the drug laminaria as a feed additive for cows. 7 tab.

Description

FIELD: feed production.

The purpose of the invention is to increase the milk productivity of cows.

Example 1. Laminaride production waste as a feed additive for cows was tested on five experimental groups of cows in each group of 50 animals.

The raw material for the production of laminaria is seaweed cabbage.

Laminaride production wastes are a wet mixture of finely ground portions of seaweed, which were extracted during the production of laminarine with simultaneous steaming at 80–90 ° C, followed by discharge of the resulting tincture and unloading the resulting waste (meal) into a bunker at 30–40 ° C (temperature of discharge from the percolator).

These wastes are obtained from plant raw materials after extraction of polysaccharides from them with drinking water at a temperature of 80-90 ° C with simultaneous steaming at the initial stage of the preparation of the laminaride.

Waste from the production of laminaria based on absolutely dry matter contains,%: hydraulics 8.05; dry matter 91.95, nitrogen 2.16; protein 13,53; ash 14.89; fiber 20.76: fat 2.24; BEV 40.53. One kilogram of waste contains feed units of 0.58 kg, digestible protein 74.41 g, calcium, 23.50 g, phosphorus, 1.20 g. In terms of natural moisture, laminaria production waste contains,%: total moisture 95.32; hydraulics 8.05; dry matter 4.68, nitrogen 0.10; protein 0.63: ash 0.70; fiber 0.97: fat 0.10; BEV 2.28. One kilogram contains feed units 0.04 kg, digestible protein 3.46 g, calcium 1.10 g, phosphorus 0.06 g. Carotene, hydrogen ions, lactic and acetic acid were not found in the waste.

The control group of cows, which also included 50 heads, received a standard ration consisting of hay, straw, silage, and grain mixture. and experimental groups received additional waste from the production of laminaria. In the first experiment with

This waste group was given instead of part of meadow hay, in the second — instead of part of barley straw, in the third — instead of part of corn silage, in the fourth — instead of part of grain mixture, in the fifth - in addition to the diet. Within 30 days, 2 kg of laminaria waste was added to the feed, then another 30 days, 8 kg per head per day. Milk yield per cow per day was monitored for all groups.

These experiments are summarized in tables 1-6.

On the basis of the experiments performed, it can be concluded that feeding dairy cows as a feed additive to laminaria production waste will expand the feed base of livestock and increase the milk productivity of cows by 1–4% while reducing their morbidity. During the continuation of the experiments (90 days), an additional 1785 kg of milk was obtained. In addition, this additive has a medicinal and prophylactic effect on the feed, as it contains up to 4.8% polysaccharides.

Comparative results on feeding a ration to cows

the proposed additive, diet with fugat (prototype) and the control diet are given in table. 7,

As follows from the table, the effectiveness of waste from the production of laminarine as a feed additive is 4.6 times higher than that of the centrate, since 37.2 kg of centrate must be used to increase the milk yield by 0.4 kg and only 8 kg of laminaria waste. those. there is an economy of feed.

In this case, when entering 37.2 kg of centrate, the weight of the ration increases by a factor of 2.5 compared to the control, and when introducing 8 kg of laminaride waste, only 1.3 times.

When an equal amount of these additives is added to the diet (8 kg each), the milk yield increases by 0.33 kg (0.5%) for a diet containing laminaria waste.
