Plant Components

Modern feed additives based on natural plant components are increasingly used as an alternative to synthetic antibiotics in animal nutrition. Phytobiotics are natural plant components that are increasingly gaining demand for use in ready-to-eat animal feed and provide proper health and microflora of the body. A scientific and economic experiment was conducted in order to determine their effect on the productivity of young pigs. We composed three groups of analogues each comprising 12 individuals, which were formed in a 15-day equalization period. According to the results of the study on the use of a new feed factor protein-vitamin-mineral supplement Efiprot in the diets of young pigs, a positive effect was observed on increase in the average daily weight gain by 4.1% and 7.1% compared with the control group. There was also seen a better absorption of nutrients in the diet compared with the control indicator. During inclusions of essential oil in the diet of the pigs, we observed an increase in the digestibility of nutrients: in particular, the level of digestibility of dry and organic matter increased in the second and third experimental groups, as well as digestible protein and digestibility of crude fat was better in the first experimental group than in the control group. During the study, there was a tendency towards better breakdown of sparingly soluble carbohydrates under the action of feed additives compared with the control indicator. Thus, the use of protein-vitamin-mineral supplement during the rearing of young pigs not only increased the efficiency of their rearing, but also led to better digestion and maintenance of the microflora of the gastrointestinal tract.

Mycotoxins have been formed in feed are secondary metabolites of fungi and are quite stable substances that have teratogenic, mutagenic and carcinogenic effects. An effective way to combat mycotoxins in feed is the use of feed additives that adsorb toxins, prevent their absorption in the gastrointestinal tract of the animal and are excreted from the body. The infl uence of coconut enterosorbent Shelltic Es on fattening and meat qualities of young pigs has been studied. It has been found in the process of fattening that the highest feed digestibility was in pigs of the experimental group, in the diet of which enterosorbent has been added. The results of studies of the chemical composition and technological properties of pork have been provided. The positive eff ect of enterosorbent on precocity, absolute average daily gain of live weight and reduction of feed expenditures per 1 kg of gain has been revealed. In pigs from the experimental group the average thickness of the fat was higher and the area of the “muscle eye” was lower compared with animals of the control group, which indicates that higher rates of carcass yield have been obtained due to faster accumulation of fat tissue. The weight of internal organs of pigs indicates the intensity of metabolic processes in the body. In experimental animals the weight of the lungs was 0,1 kg lower, and the liver and heart were higher by 0,13 and 0,01 kg, respectively. Enterosorbent had no effect on the content of vitamins in the liver of pigs of the compared groups. The content of impurities of organochlorine toxicants and toxic elements in the meat and liver of animals of the experimental group was lower than that of control analogues. Therefore, the use of enterosorbent Shelltic Es promotes more active excretion of them from the body.

We evaluated whether olive leaves (OLs) are effective as feed additives and supplements for ruminants and the potential methane reduction effects during in vitro fermentation. Two Hanwoo cows (460 ± 20 kg) equipped with cannula were fed Timothy hay and corn-based feed 3% of the body weight at a ratio of 6:4 (8:30 a.m. and 5:00 p.m.). Ruminal fluid from the cows was collected and mixed before morning feeding. In vitro batch fermentation was monitored after 12 and 24 h of incubation at 39 °C, and OLs were used as supplements to achieve the concentration of 5% in the basal diet. At 12 h of fermentation, methane production decreased in the 5% OLs group compared to that in the control group, but not at 24 h. The proportion of cellulose-degrading bacteria, Fibrobacter succinogenes, Ruminococcus albus, and Ruminococcus flavefaciens, tended to increase in the 5% OLs group at 12 h. The amount of ammonia produced was the same as the polymerase chain reaction result for Prevotella ruminicola. At 12 h, the proportion of Prevotella ruminicola was significantly higher in the 5% OLs group. OLs may be used incorporated with protein byproducts or other methane-reducing agents in animal feed.

The article covers addition of chlorella suspension, its effect on nitrogen balance, digestibility of nutrients and amino acids, pig productivity. Various feed additives, micro-element mixtures, and vitamins are used in animal nutrition to deal with the deficiency ofcertain vitamins and mineral elements in the rations. The peculiarity of chlorella suspension as a feed additive is in the ability to cultivate it throughout the whole year and in the availability of optimized technologies for its cultivation and use. Chlorella suspension is rich in proteins, minerals, vitamins, fatty acids and fiber. Introduction of chlorella suspension into pigs’ diets has helped to increase the digestibility coefficients of both inessential (by 7.5 %) and essential (by 2 %) amino acids. Feeding the animals with chlorella suspension has also resulted in the release of nitrogen retained in animals’ bodies by 13 % compared to the control group. The additional use of chlorella suspension in the diet of fattening pigs (large white) was found to increase the average daily gain by 21.9% compared to the control group which did not receive chlorella suspension. The conversion of animal feed to obtain 1 kg of live weight gain in the control group was 5.1 kg, in the experimental group - 4.2 kg, and the conversion rate of feed in the experimental group was higher by 21.4 %.Feeding young pigs with chlorella suspension increases the digestibility of protein by 4.5 %, fiber by 2.0 %, fat - 0.7 %, essential amino acids - 81.6 %. The introduction of chlorella suspension to pig rations leads to an increase in the level of nitrogen in their body by 54.7 %of that taken with feed and 69.15 % of that digested in the body. Pork production profitably using chlorella suspension stood at 12.3 % , which is more by 87,8 % compared to the control group.

Animals imported to Yakutia from other regions fall into feeding and housing conditions that differ from their usual agro-climatic conditions, which causes the problem of their adaptation. Yakutia is one of the areas where the feed of its own production has a lack of basic minerals, which affects the health and productivity of animals, which has an additional negative influence on the adaptation process of imported cattle. In order to replenish macro- and microelements in the body, it is necessary to introduce various local mineral feed additives, premixes, and use mineral salts into the ration. Under the conditions of Central Yakutia the influence of local mineral feed additives (zeolite of the Khonguruu Deposit in the Suntar district and sapropels of local lakes) containing macro- and microelements that increase the meat productivity of steers has been studied. As a result of the research the influence of local mineral feed additives on meat productivity and physiological condition of Hereford steers has been established. Influence of zeolite and sapropel in a complex with mineral salts on digestibility of nutrients of the ration and use of nitrogen, calcium and phosphorus by experimental animals has been defined. The influence of feed additives on the quality of meat products has been studied. The results have shown that the use of local mineral feed additives in the composition of ration of steers during the fattening period at a dose of 0,7 g zeolite per 1 kg of live weight of the animal and 200 g of sapropel in combination with 10 g of mineral salts contributed to the gain in live weight, carcass weight, carcass yield, yield of edible parts, and economic efficiency of fattening. For the entire period of the experiment the gain in live weight in groups was: in control group 2222,9 kg, in the 1st experimental group 2396,2 kg, in the 2nd experimental group 2471,1 kg. The total economic effect for the 1st experimental group for the period of experiment amounted to 44,3 thousand Rubles, for the 2nd experimental group 78,0 thousand Rubles or per 1 head/day 14,06 and 24,76 Rubles, respectively.

Изучена целесообразность использования в рационах телят черно-пестрой породы комплексной минерально-витаминной кормовой добавки (КМВКД). Установлено пониженное содержание в кормах таких элементов, как кальций, фосфор, магний, сера, марганец, медь, цинк и кобальт. Соотношение питательных и минеральных веществ, степень их доступности для усвоения организмом не обеспечивают их потребность. Использование КМВКД способствовало улучшению всех гематологических показателей. Все испытываемые рецепты, имеющие в своем составе разные варианты макро-, микроэлементов и витаминов положительно влияют на обменные про- цессы в организме животных. У молодняка опытной группы, получавшей подкормку по рецепту 1, количество эритроцитов в сравнении с животными контрольной группы увеличилось на 6,6, гемоглобина на 6,93 соответственно, по рецепту 2 11,05 и 11,39 по рецепту 3 16,75 и 15,27, то есть соотношение макро- и микроэлементов, имеющихся в составе КМВКД и взаимодействие между собой меди, железа и кобальта сыграли особую роль на концентрацию форменных элементов. У молодняка, получавшего подкормку по рецепту 1 количество общего белка в сравнении с животными контрольной группы увеличилось на 1,99, кальция на 16,02, каротина на 10,92 соответственно, по рецепту 2 4,91, 25,96 и 19,12 по рецепту 3 на 3,58, 27,07 и 20,21. Значительное повышение содержания белка, кальция, фосфора и каротина по сравнению с животными контрольной группы объясняется тем, что недостаток их в рационах восполнялся за счет используемой подкормки, в результате их содержание увеличилось в сыворотке, но не выходило за пределы нормативных данных и соответствовало физиологическим нормам.Practicability of using a complex mineral and vitamin feed additive (CMVFA) in the ration of black-and-white calf breed was studied. Decreased content of such elements as calcium, phosphorus, magnesium, sulfur, manganese, copper, zinc, and cobalt was registered. The correlation of nutritive and mineral substances, and the level of their availability for digestion did not provide for their need. CMVFA use facilitated the increase of all hematologic parameters. Tested recipes which had different content of sapropel and zeolite, as well as various types of macronutrients, microelements, and vitamins, positively influenced the digestive processes in animal bodies. Young stock from the test group that was receiving food additives according to recipe No. 1 showed 6.6 increase in the quantity of red blood cells compared to control group animals, and 6.93 increase in hemoglobin quantity the ones who were fed according to recipe No. 2 demonstrated the increase by 11.05 and 11.39 recipe No. 3 showed 16.75 and 15.27 increase, which means that the ratio of macronutrients and microelements present in CMVFA and the mutual interaction of copper, iron, and cobalt played a special role in the concentration of formed elements due to the fact that they are integral elements of blood. Total protein of young stock that was receiving food additives according to recipe No. 1 was 1.99 higher than in test group animals calcium 16.02 higher carotene 10.92 as for recipe No. 2 the values were increased by 4.91, 25.96, and 19.12 recipe No. 3 3.58, 27.07, and 20.21. Substantial increase in the content of protein, calcium, phosphorus, and carotene compared to control group animals can be explained by the fact that their insufficiency in animal feed was replenished due to the use of feed additives, and as a result their content increased in the serum but did not go beyond the norm and corresponded to physiological norms.

Increasing the production of pork meat requires careful work not only in terms of breeding, but also in the organization of complete feeding of animals, the correct selection of feed and feed additives containing the necessary nutrients. The purpose of the work was to analyze the use of premix in feeding young pigs on fattening. Two groups of fattening young pigs (Large White×Landrace) have been selected for the researches using the method of analogous groups, taking into account the breed, age, and live weight per 20 heads in each group with a live weight of 35 kg. Pigs of the control group have received the main economic diet, and animals of the experimental group have received an additional premix Khutorok at the rate of 10 g of premix per 1 kg of feed. The results have shown that the best age to reach 100 kg was in the experimental group of pigs – 215,8 days, which received premix with feed that characterizes their higher precocity by 36,3 days (P < 0,001) than in the control group of animals. The use of this premix had a positive impact on the livability of young animals, in the experimental group it was by 9,3 abs.% more than in the control group of animals. Thus, the best fattening traits have been possessed by young pigl of the experimental group have been received the premix Khutorok in their diet at the rate of 10 g of premix per 1 kg of feed. The obtained data indicate the feasibility of using the premix Khutorok in the feeding pigs for fattening.

Determining which forms of mineral feed additives can increase farm animal productivity is a key area of research. This study assessed the mineral composition of ruminal fluid and the effectiveness of calcium and phosphorus used by animals after the introduction of finely dispersed particles (FDP) of SiO2 (group I) and FeCo (group II) with a hydrodynamic radius of 109.6 ± 16.6 and 265 ± 25 nm, respectively. The deposition and use of calcium and phosphorus in the body of the experimental animals exceeded the control values. In group I, 30.8% more calcium was deposited (p ≥ 0.05), and in group II, the value was 30.3% (p ≥ 0.01). In the experimental groups, the calcium utilization rate was 27.3% higher in group I (p ≥ 0.05), and 28.2% higher in group II (p ≥ 0.01) compared to in the control. Phosphorus deposition was 34% higher (p ≤ 0.01) in experimental group I and 6% higher in experimental group II, compared with the control. Group I had a high utilization rate of phosphorus from the feed (with a 29% difference compared to the control). Comparison of the experimental groups revealed that the introduction of SiO2 FDP promoted an increase in the concentration of silicon, phosphorus, and calcium in the ruminal fluid. The introduction of FeCo FDP was accompanied by a decrease in the concentration of iron and cobalt in the ruminal fluid. Thus, the use of feed additive in finely dispersed form in the diet of animals was accompanied by an increase in the use of calcium and phosphorus by the animal’s body, which is advisable when intensifying milk and meat productivity. The obtained results require further research. Keywords: finely dispersed forms of microelements, ruminants, calcium and phosphorus exchange, feeding

Unbalanced mineral and vitamin nutrition of lactating cows can be a critical factor in the realization of their productive potential. The development and introduction into production of inexpensive, but effective feed additives is the main trend of improving the feeding of modern animal husbandry. Under the conditions of the Tyumen region such natural raw materials can be sapropels, which successfully combine a variety of biologically active substances. The purpose of the research was to study the digestibility of nutrients and energy metabolism in lactating cows when sapropel is included in the ration. Scientifi c and economic experiment in the study of the effectiveness of feeding sapropel lake Nepryak has been carried out in the training and experimental farm of the State Northern Trans-Urals Agrarian University. The animals of the control group have been fed the main diet. Cows of the 1st and 2nd experimental groups have been fed 300 and 500 g of sapropel per head/day, respectively, in addition to the main ration. It has been found as a result of research that the introduction of sapropel into the ration of cows has a positive effect on the digestibility of nutrients. The digestibility coefficients were higher in the animals of the 1st and 2nd experimental groups compared with the cows of the control group. Cows from the experimental groups digested all the organic substances of the ration better. During the experiment period cows of the 1st and 2nd experimental groups in contrast to the control group had higher milk yield by 11,31 and 10,38 %, respectively, milk protein yield by 10,56 and 5,95 %, milk fat yield by 17,18 and 12,99 %. It has been established that the introduction of sapropel into the ration of cows has the positive effect on the digestibility of nutrients, contributes to the increase of milk productivity, normalizes the metabolism in the body.

AbstractSix ewes were given a white clover/grass silage with a high content of cyanogenetic glycosides during the last 69 to 97 days of pregnancy (group CN+), while the five ewes of the control group (group CN−) received a white clover/grass silage with a low content of cyanogenetic glycosides during the last 67 to 92 days of pregnancy. Uniodized salt was the only mineral supplement offered. The daily intake of cyanide (in the form of cyanogenetic glycosides) and of selenium per animal was 1000 and 60 mg of cyanide and 30 and 23 μg of selenium in group CN+ and CN− respectively. Initial erythrocyte glutathione peroxidase activity (GPx) was identical in both groups. Two weeks before parturition GPx activity was significantly lower in the ewes of group CN+ than in the ewes of group CN−. The newborn lambs of the group CN+ had significantly lower erythrocyte GPx activities (P&lt; 0·01) and tended to have higher plasma creatine kinase activities (P= 0·07) than the lambs of the group CN−. The results show that the intake of cyanogenetic glycosides affects the selenium status of sheep and increases the susceptibility of lambs to nutritional myopathy if the selenium content of the ration is marginal.Plasma thyroxine concentrations in the ewes in group CN+ were not reduced but their lambs tended to have slightly lower levels immediately after birth than the lambs of group CN− (P= 0·25). The intake of cyanogenetic glycosides presumably had no or at most only a slight effect on thyroid function, presumably because the body iodine reserves of the ewes were sufficient to offset the goitrogenic effect of thiocyanate.
