Pododermatitis is a major concern in broiler production and is used as an audit criterion for poultry health checks in the United States and Europe. Pododermatitis is often associated with wet litter or poor litter quality. It is considered painful for birds and reduces the number of times the affected bird approaches the feeders and drinkers. Reduced feed and water consumption has a significant impact on weight gain, feed conversion and overall herd performance. As a result of the studies carried out to assess the degree of pododermatitis, it was observed that the quality of the paws increases or decreases, depending on the composition of the feed consumed.
Under industrial conditions, broiler chickens are constantly exposed to stressors that can increase their susceptibility to intestinal diseases, leading to reduced productivity, immune suppression, and increased mortality. Antibiotics are widely used to maintain and improve productivity in such conditions. However, in recent years, there has been a tightening of rules on the use of antibiotics in animal husbandry in order to stop them from entering food for people, as well as in connection with the emergence of strains of pathogenic bacteria that have developed resistance to a wide range of antibiotics, which pose a danger to human health and life. In this regard, manufacturers are searching for alternatives to antibiotics. The range of potential substitutes is very wide. One of the most promising groups is probiotics. In the course of the study, it was found that low-protein diets (with a low protein content, but balanced by the amino acid profile) can unlock the potential of probiotic cultures of the Bacillus amyloliquefaciens strain and, as a result, increase the livability of broiler chickens. The maximum livability index of 94.5% was observed in group 4, which received a low-protein diet using probiotic cultures of the Bacillus amyloliquefaciens strain.
The article deals with the issue of efficient processing of local plant materials. The possibility of using the pulp of Michurinskaya pumpkin grown in Belgorod region for producing candied fruit is discussed. The product is characterized by high organoleptic characteristics. Results of the physical and chemical studies and microbiological analysis are consistent with the standardized indicators. The functional properties of the candied fruit were identified and described.
The issue of providing the residents of the Russian Federation with food for a healthy diet is still currently relevant. The population lacks essential biological substances. The inclusion of various types of agricultural raw materials in food products enables to improve the quality indicators of finished products. The article presents the outcomes of research on the development of a technology for the manufacture of a multicomponent chilled dessert for proper nutrition using a locally produced plant component, namely pumpkin and apples, as the main raw material. As additional components the following ones are used: yogurt, honey, ginger syrup, stevia, blackberry, pine nuts, orange. The authors have developed three product formulations and for each of its samples the quality and quantitative characteristics assessment, the nutritional and energy value, the concentration of minerals and vitamins have been established. Based on the test results, the relevance of the production of a multicomponent chilled dessert based on pumpkin and apple processing products has been justified. The product is recommended for all population groups as a product for proper nutrition. A portion of the developed multicomponent chilled dessert with a volume of 110 to 125 g (depending on the recipe) contributes to the satisfaction of more than 15% of a person’s daily need for potassium, and with the addition of orange – for vitamin C.
The article presents the results of studies conducted on the inclusion of Presan and Selko pH feed additives produced on the basis of organic acids in the feeding diets of Ross-308 cross broiler chickens. Organic acids and their salts are used in poultry farming as an alternative to feed antibiotics, and also has the ability to prevent the development of intestinal bacterial infection, increase the resistance of the body, thereby improving the absorption of feed nutrients and increasing poultry productivity. The largest preslaughter weight was in the groups of cockerels getting the T6 diet without antibiotics adding, which is 1.92% more than the groups getting the T1-control diet. In addition, the output of the pectoral and femoral muscles was higher by chickens getting a T6 diet by 0.5 and 0.3%, in contrast to groups getting a standard diet. Thus, it has been experimentally proven that the tested feed additives Presan and Selko pH do not reduce the slaughter performance of broilers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
