Scientific And Economic Justification Of Application Of Symbiotic Polycomponent Fodder Additive In Feeding High Productive Cows

Abstract

Research has been carried out on the use of the symbiotic “Rumimaster” in balanced diets of highly productive cows in the conditions of the breeding plant “Kirovskaya meadow-bog experimental station”. The experiment was carried out on two groups of animals in the middle of lactation with a duration of 90 days. The inclusion of the feed additive “Rumimaster” in the diet of experienced cows contributed to an increase in the gross production of natural and 4% fat milk by 124.5 kg and 128.4 kg, the yield of milk fat and milk protein by 5.2 and 4.1 kg, respectively. … The differences between the groups for these parameters were in the range of 5.1-5.7%. The productivity of cows for 305 days of lactation in the experimental group was higher than in the control by 7.5%. The symbiotic “Rumimaster” promoted the activation of digestion processes, which was reflected in the increase in the time of feed consumption and the duration of the chewing gum. The cows of the experimental group showed an increase in the level of digestibility of the main nutrients. In terms of the digestibility of crude protein and crude fiber, the experimental group of cows significantly exceeded the indicators of the control group by 3.3 and 3 absolute percent, respectively. The blood biochemical parameters of the animals of the experimental and control groups were within the physiological norm. The economic evaluation of the research results showed the effectiveness of the use of the symbiotic “Rumimaster” in the diets of lactating cows, which was expressed in the receipt of additional profit from one cow in the amount of 1,344.79 rubles for the period of experience and an increase in the profitability of milk production by 2.1 absolute percent.

Impact of Inclusion of Multicomponent Synbiotic Russian Holstein Dairy Cow's Rations on Milk Yield, Rumen Fermentation, and Some Blood Biochemical Parameters

“…Multicomponent synbiotics contain both probiotics and prebiotics in addition to enzymes. Usage of synbiotics helps increase the digestibility of structural carbohydrates, cow productivity, and milk quality and optimizes the body's metabolic processes ( 4 , 7 , 13 ).…”

“…At present, the use of multicomponent feed additives based on probiotic cultures containing Bacillus subtilis and Bacillus licheniformis , which regulate the rumen microbial synthesis and allow reducing the adverse effects of evolving digestive system diseases of young and adult animals, as well as the consequences of feeding low-quality feed, is practiced worldwide ( 4 , 5 , 13 ). Moreover, the inclusion of feed additives of pro- and prebiotic action (synbiotics) contributes to increasing the productivity of cows, improving the quality of milk, and the intensity of rumen digestion ( 16 , 17 ) had shown that, the use of B. subtilis and B. licheniformis , complex enzymes, and probiotic cultures positively affects animal productivity and stimulates the fermentation of nutrients in the rumen of highly productive dairy cows.…”

“…The milk productivity of cows has increased up to 8,000-10,000 kg of milk/cow/year. However, such realization of genetic potential is possible only with a systematic approach providing a unique attitude toward optimization of feeding conditions and considering the biological peculiarities and metabolism of highly productive animals in different physiological periods (1)(2)(3)(4).…”

Influence of Using Various Levels of Protein Concentrate in Rations of Ayrshire Dairy Cows on Rumen Microbiome, Reproductive Traits and Economic Efficiency

“…Thus, the microorganisms of cow rumen play a primary role in the processes of digestion; meanwhile, it is necessary to emphasize that their functional significance is much broader. The symbiotic microflora of the rumen perform a detoxification function, participate in the digestibility of nutrients, prevent the invasion of parasites and pathogens and stimulate the development of immunity [ 4 , 5 , 6 ]. Therefore, the maintenance and functioning of the microbiota are also important factors in the prevention of gastrointestinal diseases, such as lactate acidosis, alkalosis, ketoses, laminates, mastitis and limb diseases, which significantly increase the productivity of dairy cattle [ 2 , 3 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ].…”

“…Throughout the process of the growth and development of ruminants and certain anaerobic microorganisms, which develop when feed and water are consumed, symbiotic associations are developed in the rumen. The developed symbiotic relationship between the host and the microbiota results in mutually beneficial cooperation [ 6 , 19 , 20 ].…”
