“…The creation of only an optimal microclimate is insufficient to neutralize the negative effects of anthropogenic factors. It is therefore necessary to use environmentally friendly adaptogens to stimulate the immune system of chickens when growing [2][3][4].…”

The research is devoted to the study of the influence of the modern antioxidant of the flavonoid group ‘Dihydroquercetin’ as part of the feed combination on the hematological profile and biochemical parameters of the blood of broiler chickens of the KOBB-500 cross. The content of hemoglobin and erythrocytes in the blood of broilers receiving dihydroquercetin increased, which indicates an increase in the intensity of redox processes in the body. The number of leukocytes in all groups was normal, but in the experimental groups their decrease was noted, which indicates the therapeutic and immunostimulating effect of the drug. Evaluation of protein metabolism by the content of total protein and the fraction of albumin in the blood serum showed its positive dynamics within the normal physiological values, which characterizes an increase in the intensity of assimilation processes in the bird’s body. The metabolism of carbohydrates was assessed by the content of glucose in it, and a decrease in its level indicates its increased consumption as an energy component for metabolic processes associated with intensive growth of chickens. An increase in the activity of alkaline phosphatase by 1.3-1.8 times is associated with the active growth of chickens.

Various sources of methionine in broiler chicken rations

et al. 2020

View full text Add to dashboard Cite

Fodder methionine is one of the most important amino acids in animal nutrition, and its deficiency in the ration negatively affects productivity. Currently, the following sources of methionine are represented on the Russian market of feed additives: DL-Methionine and Methionine Hydroxy. Liquid form — Methionine Hydroxy Analog Free Acid (MHA-FA) and dry (for example, МНA) — calcium salt (MHA-Ca2+). The most popular sources of dry methionine are DL-Methionine and hydroxy analog as calcium salt. Many sources state that the bioavailability of the hydroxy analog varies from 65 to 72% (one of the manufacturers of the commercial hydroxy analog claims that the availability of methionine is 84%). The experiment was carried out on broiler chickens. As a result of the studies carried out, it can be argued that the content of DL-methionine in the ration (in the amount of 65% of the hydroxyanalogue) in comparison with MHA-Ca increases the productivity of broilers: preservation – by 4%; live weight by 4.3%; average daily gains by 4.6%; feed conversion decreased by 7.1%; has a positive effect on meat productivity. Based on the data obtained during the experiment, it follows that the efficiency of MHA-Ca does not exceed 65%, compared to DL-Methionine.
