In this study, the effects of (Mentha pulegium L.) dietary supplementation on performance, carcass characteristics, some biochemical parameters, and intestinal histology were investigated in broiler chickens. Four groups were formed as control and groups treated with pennyroyal at different levels (0.25%, 0.50%, and 1.00%). In the experiment. Each group had eight replicates. A total of 192 broilers were used in the study with six broilers in each replicate. Water and feed were ad libitum provided. Adding different levels of pennyroyals to broiler rations significantly affected performance parameters; an increase in final body weight and carcass yield and a decrease in total feed intake and the conversion rate was observed (P<0.05). Serum cholesterol, malondialdehyde, and glutathione values were also affected by the addition of pennyroyal (P<0.05). Pennyroyal was effective in vitro against S. enteritidis, E. coli, S. aureus, S. abortus ovis, B.anthracis sterne strains. Besides, it increased the duodenum villus’ length compared to the control group (P<0.05). On the other hand, pennyroyal did not affect carcass and visceral organ weights, several serum biochemical values (P>0.05). As a result, it was concluded that pennyroyal at the level of 0.50% in ration was effective on health and growth performance of broilers.

Abstract Background The major storage form of phosphorus in plant-derived feed is presents by insoluble phytates and not digested by animals. Microbial enzymes phytases are able to hydrolyze phytates and are widely used as feed additives in animal nutrition to improving the utilization of phytate-phosphorus in diets and reducing manure phosphorus excretion to the environment. However, no single phytase can perform effectively under various conditions of digestive systems and dietary compositions. That's why there is a constant search and development of new effective feed phytases preparations. The objective of this study was to study the effect of AgpP-P phytase supplementation on productivity, nutrient availability, veterinary-sanitary assessment of meat and serum biochemical parameters of Hubboard broilers. Results Results showed that phytase supplementation increased body weight and absolute weigh gain in broilers, while reducing the total amount of feed consumed by birds (P < 0.05). Phytase improved the availability and absorption of organic nutrients, calcium (Ca) and phosphorus (P). However, no differences were observed for nitrogen (N) (P < 0.05). Phytase supplementation increased Ca and P contents, total protein (TP) level and alanine aminotransferase (ALT) activity, and reduced urea level, aspartate aminotransferase (AST) and alkaline phosphatase (ALP) activities in serum, respectively (P < 0.05). The meat of phytase-fed broilers meets Russian State Standards (GOST) for fresh good-quality meat based on organoleptic, physicochemical and bacterioscopic characteristics. Conclusions The results of present study demonstrated that addition of AgpP-P phytase to the diet of broiler chickens has a positive effect on the nutrient availability and productivity of birds, while reducing the total amount of feed consumed by chickens. Biochemical parameters in serum remained within the physiological norm. The meat of phytase-fed broilers met the Russian State Standards (GOST) for fresh good-quality meat. Thus, it is shown that AgpP-P phytase has the potential for use as a feed additive in poultry farming.

Abstract The problem of using high-energy diets for early maturing bird crosses is insufficient enrichment of diets, both qualitative and quantitative, with microelements. The aim of the study was to study the effect of different levels of metabolic energy (ME) of diet on productivity and morpho-biochemical parameters of broiler chickens of the Arbor Aсres cross. 3 groups with different content of ME were formed (n = 30). The control group contained 12.61 MJ / kg DM, treatment I - 13.3 MJ / kg DM, treatment II - 14.7 MJ / kg DM. So, live weight of broilers from the II experimental group was higher by 59.9% after the third week of the registration period relative to the control group, and by 18.8% (P ≤ 0.001) compared with I experimental group. At the end of registration period, broilers of II group were superior to the control and I experimental groups by 27.2% and 17.5% (p≤0.01), respectively. At the same time, in the group with the maximum OE content (group II), the level of leukocytes decreased by 9.2%, and the amount of hemoglobin increased by 6.6% compared to the control. By the end of the experiment (35 days), the activity of serum transamylases decreases in experimental groups I and II: ALT activity by 39.2% and 16.7% (P ≤ 0.05); AST by 3.8% and 1.9%, respectively, compared with the control. Thus, the content of main macronutrients of blood serum in animals with the maximum level of MA of the diet (group II) decreases: Fe by 4.95%, Mg by 3.42%, P by 16.7% (P ≤ 0.05) relative to control. Thus, an increase in metabolic energy in the diet of broiler chickens has a positive effect on productivity, causing a decrease in the content of macronutrients in blood serum. The research was carried out with financial support from RSF (20-16-00078).
