The purpose of this study was to evaluate the viability and growth rate of piglets after weaning, the content of lipids in the blood and liver, antioxidant activity (AOA) and lipid peroxidation (LPO) when various additives are used in feed. The experiments were performed on two crosses of piglets obtained from Large White breed sows and Landrace breed boars. Twenty to 28 animals were randomly a...

To obtain high efficiency from animals, it is necessary to maximize the ability benefit feed, as well protect animal health. One of important applications in this direction feed additives. Feed additives are plant and products microorganisms that increase fish production welfare, improve digestion digestive system microflora contribute preservation nutrients feed. Although tissues used enzyme p...

The aim of the study was to investigate the effects of a standardized mixture of a commercial blend of phytogenic feed additives containing 5% carvacrol, 3% cinnamaldehyde, and 2% capsicum on utilization of dietary energy and performance in broiler chickens. Four experimental diets were offered to the birds from 7 to 21 d of age. These included 2 basal control diets based on either wheat or mai...

Massive amounts of pig manure are produced by intensive pig farm in China, and the composition of pig manure has changed much due to the use of feed additives. However, little is known about the exact Cu (copper) feed as additives or present as contaminants in pig feed and the residues in feces. One hundred and thirty-seven feeds and one hundred and forty-two fecal samples from 48 pig farms wer...

The aim of the study was to evaluate the effect of organic acids and the prebiotic fructans on egg production and eggshell quality when added to the layer diet with different levels of calcium and phosphorus. The experiment was carried out on 168 Bovans Brown hens, allocated to 14 groups of 12 replications. Each hen (replication) was kept in an individual cage 40 cm × 40 cm in size. A 2 × 7 fac...

In this study, the effects of boric acid and humate supplementation into hen diets on egg production and quality parameters and blood cholesterol levels were examined. For this aim, totally 160, 40 weeks of age, Hyline-White 98 layers were randomly divided into control and 3 treatment groups each containing 40 birds and 10 replicates (each with 4 birds). There was no boric acid or humate supple...

Beauchemin and Rode (1996) recently reviewed the use of enzymes in ruminant diets, however, enzymes in the form of crude whole fungal cell preparations have been used to enhance ruminant production for many years. This paper aims to investigate the similarities between the emerging feed enzymes and fungal feed additives, and to use this information to speculate on potential modes of action of d...

Relevance. Modern livestock breeders face an important task of producing organic products, in Russia this is regulated by the Federal Law “On Organic Products” (from 01.01.2020), it allows producers to enter state register and mark products with “organic” sign. There a problem deterioration quality milk, low content fat, protein, SOMO, deficiency macro-and microelements, vitamins, which associa...
