Исследование пектолитической способности дрожжей Saccharomyces Cerevisiae

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.

Gastrointestinal infectious diseases accompany the growth of animal and poultry farming: as the livestock population increases, its high concentration on farms raises the level of mortality and rejection, thus reducing the overall safety and productivity. Probiotics and prebiotics used as feed additives may be an effective preventive measure. The article describes a sustainable and environmentally friendly method for obtaining prebiotics of pectin oligosaccharides by hydrolyzing apple pomace pectin in whey with Saccharomyces cerevisiae to produce bifidogenic animal feed. The 5:1 ratio of whey and apple pomace increased the yeast biomass by 56.3% after 24 h of fermentation and introducing 0.3% yeast by weight. The pectin hydrolysis products triggered an intensive growth of the substrate. The hydrolysis products contained 32% oligosaccharides of average molecular weight. The enzymatic hydrolysis of whey-apple mixes with a β-galactosidase preparation by deep cultivation of Bacillus licheniformis prevented the negative effect of serum lactose consumption, as well as increased the yield of yeast biomass. The optimal hydrolysis parameters were pH 6.0, 25 °C, 0.04% enzyme, and 6 h. The technological process included the following stages. The raw materials were prepared as a whey-vegetable mix (5:1), which was gradually heated to 65 °C. After cooling down to 22-25 °C, dry Saccharomyces cerevisiae provided fermentation and deoxidation. After introducing lactase enzyme and final thermal treatment, the finished feed additive contained 10% solids, 3.5% nitrogenous substances, 0.6% pectin, 0.3% pectin oligosaccharides, and 0.2% residual lactose, as well as vitamins and minerals.

The aim of the study is to investigate the effect of a feed additive with pectin oligosaccharides in diets on the physiological state and live weight gain of Bessonovsky dairy type calves. Objectives: to study the effect of a bifidogenic feed additive obtained by hydrolyzing apple pomace with Saccharomyces cerevisiae yeast in a whey medium. The developed bifidogenic feed additive is an additive that regulates the balance of microflora in the digestive tract by suppressing the activity of pathogenic microflora and stimulating the growth of its own beneficial microflora - bifido- and lactobacilli. The feed additive is a product of hydrolysis of apple pomace with Saccharomyces cerevisiae yeast in a whey medium. The object of the study is 1-month-old Bessonovsky dairy type calves. The study was conducted in the Belgorod Region in the SPK Kolkhoz imeni Gorina. Two groups of animals were selected for the study: the 1st – control, the 2nd – experimental (formed by the method of pairs-analogues) with 12 heads in each. The calves of the control group were fed the rations adopted on the farm, and the experimental group was additionally given a bifidogenic feed additive. The dosage of the additive was 200 g per head per day for 60 days. During the study, the animals were examined, their physiological condition was monitored. The study revealed an increase in the live weight gain of the calves of the experimental group by 3.9 % compared to the control. A more pronounced resistance of the calves of the experimental group to diarrhea, an increase in the appetite of the animals were noted. We recommend using a bifidogenic feed additive with pectin oligosaccharides in the rations of calves during rearing in order to increase the live weight gain.
