Wood waste of forest industry of siberia for feeding cows

Abstract

Full realization of genetic potential of productivity of livestock in the conditions of industrial technologies is impossible without using in its diets of various biologically active additives providing increase in productivity and standardization of indicators of homeostasis. The research has been conducted in “Breeding Farm Taezhny” Ltd, Sukhobuzimsky territory of Krasnoyarsk region. The influence of feeding coniferous flour and pine nut shells on milk productivity of black-motley breed cows at the age of the second calving has been studied. Three groups of 5 cows in each were formed. The period of the experiment lasted 100 days. As a result, the analysis of composition of the studied feed additives, milk productivity, hematological and biochemical blood tests were made. Milk yield of the cows receiving coniferous flour in addition to the main diet was higher than in the control group by 13.5 %, and the cows receiving a shell of pine nut – by 4.3 %, in terms of basic fat content by 22.7-15.7 %, respectively. The increase of milk productivity by adding the coniferous flour allowed reducing the cost of 1 kg of milk by 2.2 rubles or 13.1 %, increase profits by 9.442 rubles or 36.5 %.

Effect of Temperature with Different Composting Ages of Sawdust

“…Common wood wastes include bark, scrap lumber, sawdust, construction and demolition, offcuts, ash from burning wood wastes, and broken furniture [1]; [2]. Wood waste or wood chips are great materials for many purposes [3]. Wood is a natural and renewable resource that is biodegradable and has exceptional mechanical and thermal properties [4]; [5].…”

Morphological and biochemical cow blood parameters fed with forest products and an enzyme preparation

“…It has been established that in the shell of pine nuts, there is a large number of valuable nutrients and biologically active substances: proteins, lipids, macroand micronutrients, tannides, flavonoids, polysaccharides. In addition, the shell has a low cost [21,22].…”

“…The dosages of coniferous flour and pine nut shells were established as optimal in the previous studies on cows [21], the dosage of Amilosubtilin G3x was based on the manufacturer's recommendations [23], and the dose of arabinogalactan was chosen according to the literature [25].…”

The effect of immunogenetic factors on productive longevity and reproductive qualities of cows

“…It is necessary to reproduce tribal mother cows and father bulls. Implementation of the genetic potential of milk productivity [1] is impossible without various biologically active additives which increase productivity and normalize indicators of homeostasis.…”
