Opis:
The paper presents the review of scientific publications of world literature on the use of the larvae of black soldier fly (Hermetia illucens) when feeding poultry. Nowadays, the issue of replacing traditional sources of protein when feeding poultry is very urgent, especially in connection with the global food crisis. Insects are the natural food of most birds; thus, the use of fly larvae for feed production has a biological basis. The research results presented in published works show that there are no negative effects on bird health and meat quality when feeding poultry, quail and other birds. In some cases, the experimental groups of birds gained weight slightly more slowly than the control group. Other reports indicate that birds grew at the same rate as normal birds. The quantity and quality of eggs did not differ significantly, but dietary changes affected the colour of yolks and eggshell. The effect of the addition of live larvae to the diet of young turkeys on the weight characteristics of was studied. Replacing 10% of the daily amount of feed with live Hermetia illucens larvae in the diet of turkeys showed that the daily feed intake and body weight gain of the experimental birds were significantly higher compared to the control groups, which led to a significantly higher body weight of chicks at the age of five weeks (2.19 kg vs. 2.015 kg, respectively) and a significantly lower feed conversion rate. Most researchers agree that replacing protein in poultry feed with insect flour should be partial, in the 15–30% range. Feeding with larvae that have undergone processing – grinding, chitin removing, heat treatment – is more preferable than using whole larvae, since the chitinous membrane makes larvae difficult to be digested in the digestive tract of birds.

Opis:
The experimental material consisted of 42 sows divided into 3 feeding groups, each containing 14 sows fed complete compound feed varying in protein content. Protein and amino acid content of the feed fed to the control group was in compliance with Polish standards. Protein content in the experimental groups was reduced by 10% and 20%, respectively. At the same time, lysine, methionine, threonine and tryptophane content was supplemented to the level of the control group. All pregnant and lactating sows were fed individually. The condition of the sows was determined by measuring the thickness of backfat at the P2 position on days 30 and 105 of pregnancy and on day 25 of lactation. The data analyzed in the study included: the total number of piglets born, their body weight gain, milk composition, weaning-to-estrus interval and the farrowing rate. Protein content of the compound feed did not have a significant impact on the increment in backfat during pregnancy and losses during lactation. The sows fed compound feed with reduced protein content gave birth to 0.7 and 0.6 less piglets per litter than the control animals. However, due to lower losses, they bred 0.3 and 0.4 more piglets than the control sows. Average body weight of a piglet on day 21 was 0.5 kg lower in the experimental than in the control group. Dry matter, protein, fat and lactose content of the sow’s milk did not depend on protein content of the feed. The weaning-to-estrus interval in the experimental groups was one day longer than in the control group. The reproductive rate accounted for 86% and was comparable in all the groups.

Opis:
A group of 10-day-old chickens was experimentally infected with a dose of 500 infective eggs of Ascaridia galli (Schrank, 1788) (Nematoda). Forty-nine days post infection the chickens were necropsied and the infection intensily and prevalence were determined. The group maintained on the feed containing 11% of protein showed higher infection intensity and prevalence compared to the chickens fed a diet containing 19% of protein. The addition of vitamin B₂ to the feed containing 11% protein resulted in lower intensity and prevalence of the infection. In both series of experiments no effect of Zn-bacitracin or vitamin B₂ on infection intensity or prevalence was observed for chickens fed feed containing 19% of protein.

Swine breeding is a branch of agriculture with high level of development and traditional in Belarus. The problem of basic directions in development of swine breeding is examined in the paper. In conclusion the main reserves for growth of the economic efficiency of pork production are found in strengthening of food reserve and using of complete feed mixture balanced on feed protein, increasing of leguminous plants and many other factors.
