The invention relates to agriculture, in particular to the production of feed for ruminant animals.

It is known to use as feed additives waste paper production of joint ventures or feed products in the form of fermented cellulose obtained from the production of rayon pulp 1 2 3.

However, agriculture experienced a shortage of forage resources, without which the growth of animal production intensification cannot be achieved.

The purpose of the invention. - expansion of the feed base for livestock.

The goal is achieved by the use of cello lignin — a waste of furfural production — as a feed additive.

To date, in some cases, cellulignin has been used as a fuel for the SZZ.

For the production of furfuro, la use of pentosan-containing raw materials, in particular low-quality hardwood. The technological chip is loaded into diffusers, where at a pressure of 3 atm a tanning extract is extracted from it. After that, the chips enter the hydrolysis apparatus, where, at a pressure of 10-11 atm and a temperature of 175-177 ° C, the raw material is partially hydro. is licensed; at the same time, along with the steam from the appliance, products, including furfural, are gradually taken out of the gas-o6pa3Hjie .- The waste of this production is cello-lignin.

Cellolignin contains kS-SO% dry matter, of which 5 sajry, fiber, 1.64-2 protein, 3-nd mineral substances. The specified product is introduced either as an independent feed additive in the diet of ruminants or as an integral part of granulated and briquetted feed. Waste from furfural production — cello lignin is neutralized with lime milk, chalk or urea to convert it into a full-fledged ruminant additive; The pH rises from 3.5 to j8-5.5. When neutralized with lime milk and chalk, the feed is enriched with calcium and when neutralized with urea, with nitrogen.

Experiments on feeding the fodder with the use of neutralized cello lignin, young cattle were given at the Shumerminsky farm of the Chuvash ASSR.
