Introduction. Modern poultry farming in Ukraine is one of the most developed branches of agriculture, which is associated with the involvement of world technologies of poultry breeding and the maximum realisation of its genetic potential (Lagotiuk V.O., 2018). The latter largely depends on a number of factors, including the state of the intestine (Hollemans et al., 2020) and its microbiome (Dyachenko L.S. et al., 2018), as it is here that the digestion and absorption of nutrients that ensure the growth and development of the organism takes place.
The intestinal system is exposed to harmful factors and microorganisms that threaten the integrity of the intestinal wall. Strengthening the integrity of the intestinal mucosa is a key objective for feed additives aimed at promoting broiler health. Intensive rearing technologies, especially in meat poultry production, are based on balanced protein feeding, which often leads to bacterial infections induced by pathogens (Hoover J., 2020). This causes economic losses and reduces the profitability of the industry, which makes it important to find new means to prevent intestinal infections in broilers (Hauck R., 2017, Dyachenko L.S. et al., 2018, Fathima et al., 2022).
Recently, the antibacterial effects of monoglycerides and their positive impact on broiler performance have been demonstrated. The beneficial effects of monoglycerides are attributed to their effect on the integrity of the intestinal barrier and inhibition of the growth of resistant strains. However, the mechanisms of action of monoglycerides are not yet fully understood.
Objective. To determine the effect of monoglycerides on the performance and fibronectin content in broiler intestinal tissue as a marker of integrity of the intestinal barrier.
Materials and methods. The study was conducted on Cobb 500 broilers. Two groups of day-old chicks were formed: the experimental group (55 thousand chicks) and the control group (36 thousand chicks). The stocking density in the control group was 20.6 chicks/m², and in the experimental group – 21.4 chicks/m². The experimental group was fed with a solution of monoglycerides with C3-C10 fatty acids (MUFA) from day 1 to day 7 and from day 16 to day 22 at a dose of 0.5 litres of the product per tonne of drinking water. On days 31 and 45 of life, intestinal fragments were collected for analysis.
Results. Studies have shown that MJC reduces chick mortality in the first 5 days and after culling by 0.24% and 0.6%, respectively, compared to the control group. The average daily weight gain in the experimental group was 2.1% higher and the meat yield was 0.92% higher than in the control group.
Conclusions. Monoglycerides have a positive effect on reducing mortality and increasing productivity of chickens.
