The use of a feed additive on the base of beekeeping products «Vinivet» in the feeding of juveniles of Steelhead salmon

Currently, there is a rapid development of commercial salmon farming in Russia, which has grown almost 3 times in terms of production since 2013 and exceeded 116 thousand tons in 2020. In turn, this requires the appropriate development of the feed base and the development of methods for the effective use of fairly expensive fi sh feed. From these positions the involvement of the feed additive “Vinivet”, which is a waste of beekeeping in the feed production for fi sh as a protein additive is relevant. The feed additive “Vinivet” contains bee products such as bee bread and slumgum, a significant complex of vitamins, amino acids, macro- and microelements. The purpose of the work was to assess the influence of the feed additive “Vinivet” on the livability of juveniles, growth rate and feed consumption of rainbow trout of Steelhead salmon breed when growing in a recirculating aquaculture system. For the experiment juveniles with an average juvenile weight of 2,37±0,72 g have been selected, from which the control and 3 experimental groups have been formed. The control group has received a standard starting compound feed as the main diet, the 1st experimental group in addition to the main diet has received the additive “Vinivet” in the amount of 2,5 % of the mass of the main diet, the 2nd experimental group has received 5,0 % of the additive, and the 3rd experimental group in the first week received 2,5 % of the additive, and from the second week of studies the dose of the additive was increased to 5 %. The conducted studies have shown that the inclusion of the feed additive “Vinivet” in the feed when growing juveniles of Steelhead salmon is most advisable by introducing it at the dosage of 2,5 % of the mass of the main diet in the first week of cultivation, followed by the increase in the dose to 5,0 %, which allows achieving the highest fi sh productivity of pools in the recirculating aquaculture system compared to all variants of the experiment and by 24 % compared to the control group.

In order to increase the meat productivity of broiler chickens, increase production volumes and reduce the prime-cost of poultry products, it is necessary not only to ensure balanced feeding and compliance with production technology but also to include in the poultry diet non-traditional additives, biologically active substances that contribute to the normalization of metabolic processes and improve the digestibility of feed nutrients. One of these dietary additives is Betulin extracted from birch bark, which has antioxidant and immunomodulatory properties. In this regard, the purpose of the research was to study the influence of compound feed with the introduction of 2 % feed additive based on a synthetic microspherical nanoporous carbon carrier containing biologically active Betulin in its composition on the productivity of broilers. The results of studies on broiler chickens using compound feed with 2 % feed additive have been presented in the article. It has been found that the feed consumption per 1 kg of live weight gain in poultry of the experimental group have been lower by 9,5 % due to better absorption of nutrients, the live weight of broiler chickens of the experimental group at the age of 42 days was 2625,6 g and it was higher than the control group by 3,68 %. The digestibility of crude protein and fat reached 92,73 and 88,03 %, which exceeded the control group by 1,03 and 3,03 abs.%, respectively. It has been found that the use of compound feed with 2 % of the feed additive with the biologically active substance is of practical importance in connection with the increase in the productivity of broilers and the level of profitability of meat production by 8,2 abs.%.

The data on the study of the effectiveness of a new probiotic based on strains B. toyonensis B-13249 and B. pumilus B-13250 when growing shrimps are presented. The experiments were carried out on a private farm in Kazakhstan. The control group of shrimps, which did not receive the probiotic, completed the molting process on the 28th day of the experiment, and the experimental group – 10 days earlier. It was also found that the probiotic has a positive effect on the hydrochemistry of water in recirculating aquaculture system (RAS). The concentration of ammonium (NH3/NH4 +), nitrite (NO2) and nitrate (NO3-) nitrogen in the experimental group did not reach the limit value, in contrast to the control. Based on the obtained results, this probiotic can be recommended for greening aquaculture. The dosage of the probiotic when applied with brine shrimp as feed for shrimp is 1 g/100 g of dry cysts. The dosage of the probiotic when the RAS is added to the water is 5 g/600 l of circulating water once a week.

Изучены особенности пищевого поведения коров-первотелок при скармливании ферментативно-пробиотических препаратов. Для изучения влияния пробиотиков на основе целюлозолитических бактерий рубца жвачных проводился опыт в условиях хозяйства Вологодской области. Были сформированы 3 группы первотелок черно-пестрой породы по 12 голов методом пар-аналогов с учетом кровности, удоя матерей за наивысшую лактацию, живой массы, количества дойных дней после отела и суточного удоя. Животные контрольной группы получали основной рацион, коровам I опытной группы дополнительно скармливали по 50 г на 1 голову в сутки кормовую добавку на основе целюлозолитических бактерий рубца коров, а II опытной — такое же количество добавки на основе целюлозолитических бактерий рубца оленей. Продолжительность скармливания добавок составляла 90 дней. В результате исследований было установлено, что использование ферментативно-пробиотических препаратов положительно повлияло на пищевую активность и уровень молочной продуктивности первотелок. Коровы I и II опытных групп, получавшие дополнительно к основному рациону ферментативно-пробиотические препараты в сравнении с контрольной группой имели более высокие показатели по затратам времени на потребление корма — 8 и 25 мин., соответственно. Время, затраченное на жвачку, у первотелок II опытной группы было больше на 12 мин., чем у животных контрольной группы, в результате индекс пищевой активности у них был выше на 0,026 по сравнению с контролем. Использование добавок способствовало увеличению молочной продуктивности коров I и II опытных групп, по сравнению с контрольной, на 207 и 151 кг. Полученные результаты подтверждают положительное влияние ферментативно-пробиотических препаратов в кормлении коров, так как они способствуют повышению их пищевой активности и молочной продуктивности. The features of first-born cows’ nutritional behavior when feeding enzyme-probiotic preparations have been studied. To study the effect of probiotics based on the ruminants’ cellulolytic rumen bacteria, an experiment on a farm in the Vologda Oblast has been conducted. There were formed 3 groups of black-and-white first-born cows of 12 heads by the method of pairs-analogues, taking into account pedigree, mothers’ milk yield for the highest lactation, live weight, the number of milking days after calving and daily milk yield. The animals of the control group received the main diet, the cows of the I experimental group were additionally fed 50 g per 1 head per day of a feed additive based on cellulolytic bacteria of cow rumen, and the II experimental group were fed the same amount of an additive based on cellulolytic bacteria of deer rumen. The duration of feeding the additives was 90 days. The research found that the use of enzyme-probiotic preparations had a positive effect on the first-born cows’ nutritional activity and milk productivity level. The cows of the I and II experimental groups who received enzyme-probiotic preparations in addition to the main diet had higher indicators for the time spent on feed consumption in comparison with the control group — 8 and 25 minutes, respectively. The time spent on rumination was 12 minutes longer in the first group of experimental animals than in the control group; as a result, their food activity index was higher by 0.026 compared to the control group. The use of additives contributed to an increase in the milk productivity of cows of the I and II experimental groups, compared with the control group, by 207 and 151 kg. The obtained results confirm the positive effect of enzyme-probiotic preparations when feeding cows, as they help to increase their nutritional activity and milk productivity.

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.

Fattening Pigs

This article presents the results of the effective use of biologically active substance that belongs to hydrolyse class “Lysozyme G3” in the composition of pigs premix. New premix that can balance the main grains in pigs feeding has been developed. The main grains are wheat, corn, barley. These compounds are included into pigs feeding ration and they are the main crops in the South of Ukraine. The effect of using this new premix that contains the enzyme preparation “Lysozyme G3” for fattening pigs was also investigated. The productive effect of enzyme preparation in the rations with the same nutritional value for fattening pigs and its effect on the nutrients digestibility were studied. Experimental research activities were conducted at the agricultural enterprise “Avangard-D” LLC, Ovidiopol District, Odessa Oblast. The changes in live weight, as well as gains of fattening pigs at the age of 4, 5, 6 and 7 months were studied in the scientific and economical experience. During the main period (120 days), the increase in pigs live weight was observed in all groups. Thus, in the control group, this indicator changed from 27.8 to 107 kg; in II experimental group – from 28.1 to 109.2; in III experimental group – from 28.0 to 111.7 kg. When removing animals from fattening, the difference in live weight between the III experimental and control groups was 4.4% and it was statistically significant (P > 0.95). The average daily gains in piglets of II and III experimental groups significantly exceeded the indices of control one by 2.4% and 5.7%, respectively. The nutrients digestibility in animals of all experimental groups was studied to analyze more carefully. The analysis of digestibility indices in pigs rations during experiment (when pigs are fed with premix that contains biologically active substance Lysozyme G3), and its content in the ration indicated that nutrient digestibility indices had changed into the direction of increase. Feed consumption was calculated after analyzing these indices. Thus, the smallest feed consumption per unit of live weight gain was established in the third experimental group, where it was 3.2 feed units and was less in comparison with animals of the control group by 3.4%. During scientific and economical researches, blood samples were taken from animals of the first control group and the third experimental one for morphological and biochemical studies. It was found that the blood parameters of experimental animals during the entire period of fattening were within the physiological norm. The amount of protein in the blood indicates that animals of experimental group have higher growth rate by 10.9%. The economic indicators directly reflected above mentioned facts when the calculation of the economic part of the research were carried out. Thus, we got 1870.5 UAH from the first group, 1934.3 UAH from the second group, 1989.4 UAH from the third group, selling products from one head. Accordingly, the level of profitability of pork production was: in the first group (control) – 13.5; in the second (1 kg/ton of premix) – 16.5%; in the third (2 kg/ton of premix) – 19.8%.

The article presents research materials to study the possibility of increasing the milk productivity of high-yielding cows through the use of new technology of their feeding - through the use of protected from cleavage in the rumen protein and starch in the feed additive TEP-mix. The scientific and economic experiment was carried out on dairy cows-analogues of the first half of lactation of the Ukrainian Black-Spotted dairy breed. During the study, the actual chemical composition of feed was determined, feeding rations and compound feed recipes were developed taking into account the content of fissile protein and milk productivity of experimental animals, the actual feed consumption by cows, milk productivity, milk quality, calculated cost-effectiveness of the studied energy supplement. The difference between the rations of the control and experimental groups was the structure and composition of the feed. In the experimental group, part of the concentrated feed was replaced by energy-protein supplement TEP-mix, with a high degree (65 %) of protection against splitting in the rumen, which increased this figure in the diet of cows in general. The use of new feeding methods increased the productivity of cows with natural milk by 2.0 kg compared to the control group, the amount of fat and protein in milk - by 0.20 % and 0.17 %, respectively. As a result, the average daily hopes for the period of the experiment in terms of basic fat in the experimental group was higher by 3.9 kg, which allowed to obtain 349.2 kg more milk per cow in 89 days. In determining the economic efficiency of the use of high-yielding cows in the feeding of additives TEP-mix allowed to obtain an additional average for the period of the experiment up to 32.59 UAH. per 1 cow per day or UAH 0.98. per 1 kg of milk. The use of feed additives with a high content of protein and starch TEP-mix will allow you to balance the feeding rations of cattle more accurately, adjust the diet of high-yielding dairy cattle in the early stages of lactation to obtain maximum productivity while maintaining health and productive longevity.

Abstract The paper discusses the effect of a newly developed complex feed additive Grainbiosorb used in complete feed on livability, age of first egg laying, egg productivity, and feed consumption for the production of 1 dozen eggs of laying quails of the Texas white broiler breed. The scientific experiment was carried out in the experimental vivarium of Krasnodar Research Centre for Animal Husbandry and Veterinary Medicine according to the standard technique recommended by the Federal Scientific Center “All-Russian Research and Technological Institute of Poultry” of Russian Academy of Sciences, (Sergiev Posad, 2013). The developed complex feed additive Grainbiosorb consists of fermented brewer’s spent grain, a mineral sorbing complex and probiotic microorganisms. Brewer’s spent grain is pre-fermented with probiotic bacterial concentrate, consisting of lactic acid, and propionic acid microorganisms. The use of fermented brewer’s spent grain in combination with a mineral complex can solve the problems of metabolism, digestion, exposure to heavy metals and thereby increase productivity and contribute to obtaining safe poultry products. The livability of the quail population in experimental and control groups was the same and amounted to 90.0%. The quails of the first group laid the first egg at the age of 44 days, while the quails of the second group at the age of 42 days. Gross egg production for the period of the experiment per the initial laying quail and the egg production for the average laying quail increased in the experimental group relative to the control by 3.8%. The intensity of egg production in the experimental group increased by 2.3 abs. % relative to that in the control group. Feed consumption for the production of 1 dozen quail eggs decreased by 5.5% in the experimental group, relative to the control.
