The effect of phytogenic feed additives on the performance, meat quality and coccidial infection rates of rabbits

The aim of the study was to evaluate the effect of herbal supplementation on rabbits’ health and production parameters. In experiment with herbal food additives, at 90 days of age animals fed with phytogenic additives (oregano, garlic and rosemary) had higher body weight compared to the group fed with coccidiostat. In experiment with herbal water additives (garlic extract or oregano) the phytobiotic supplementation had no effect on weight gains of animals. The highest body weight on slaughter day was obtained by rabbits drank water with garlic extract. Parasitological tests performed at 91 days of age showed that lowest average number of coccidia oocysts per gram of faeces (OPG) in “garlic” group (48.0 OPG) and the highest in control group (308.6 OPG). The research showed that feed with herbal supplementation is willingly eaten by rabbits, contributes to faster weight gains and has a positive effect on meat quality.

ABSTRACT The objectives of this research were to evaluate the effects of commercial probiotic and chitosan as food additives on the quality and meat composition of 36 New Zealand White rabbits (57 ± 8 days old and 1,648 ± 0.194 kg) and on the fatty acid profile of caecotrophs. The treatments were CT (diets without inclusion of additives), PRO (inclusion of 4 g / kg of commercial probiotic) and CHI (inclusion of 4 g / kg of chitosan). The additives increased triglycerides and decreased urea compared to the control group, as well as increased oleic and linoleic acids, Ʃ unsaturated, Ʃ monounsaturated and Ʃ polyunsaturated in caecotrophs. CHI animals showed a decrease in myristic and palmitic acids compared to PRO. CHI decreased the meat's crude protein and the meat's fat. In addition, there was a decrease in omega-3, omega-6 and the relationship unsaturated and saturated fatty acids for the CHI group and an increase in erucic acid and a decrease in the rate of hypocholesterolemic acids. As a conclusion, the data showed that the animals that ingested probiotic had better meat quality, for having better fatty acid profile and hypocholesterolemic index, compared to the treatment with chitosan. The additives improved the caecotrophs fatty acid profile.

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.

Effect Of Feeding

The research was conducted on the effect of bird broilers fed with different hybrid rye doses on the fatty acids profile in muscle. The first experiment was performed on 3 geese broilers groups fed with hybrid rye, oats or hybrid rye and oats mix in proportion 1:1. No effect of the hybrid rye feeding of geese on the SFA level in meat was observed, but the MUFA level was significantly higher and PUFA level and n-6/n-3 PUFA ratio were significantly lower than in geese fed with oats. The second experiment was performed on 3 chicken broiler groups fed with mix of corn, wheat, soybean meal and rapeseed oil (control group), and fed with an addition of 10% or 20% hybrid rye in diet (experimental groups). No effect of hybrid rye feeding of chicken broilers on the meat quality and SFA level was observed. However, the MUFA level was higher and the PUFA level and n-6/n-3 PUFA ratio were lower in meat of chicken broilers fed with hybrid rye. In conclusion hybrid rye is a healthy ingredient in the diet of studied birds and may be used up to 20% in chicken broilers and 50% in the diets of geese. A 100% hybrid rye in geese diet caused lower final body weight.

Positive Effect

The article presents the results of studying the impact of the spore-forming probiotic “Olin” and the prebiotic “Eсofiltrum” on the meat quality of broiler chicken carcasses of the Ross-308 cross. In the course of the research, it has been found that the inclusion of these preparations in the broiler diet has a positive effect on the studied indicators: the pre-slaughter weight increased by 4.3-5.7%, the weight of the gutted carcass by 4.6-6.2%, the muscle weight 4.8-6.5%, the weight of the loin muscles by 5.7-8.2%. The ratio of edible parts to inedible parts is 4.14 in the third experimental group, 4.08-in the second, and 4.04-in the control. Based on the results of the anatomical cutting of broiler carcasses and according to the fatness indicators the poultry carcasses of the third and second experimental groups, 87.5% and 87.2%, respectively, belong to the first grade, and the yield of the first grade carcasses is 86.2% in the control group. Meat products obtained from both the control poultry and the poultry of both experimental groups has no off-aroma odor and taste, the meat is juicy, tender and aromatic. The products obtained from broiler chickens, whose ration includes the probiotic “Olin” and the prebiotic “Ecofiltrum”, do not have any deviations from the established standards and norms. During the research, it has been found that the use of the studied drugs has a positive effect on the meat quality of poultry carcasses. However, broiler chickens receiving the probiotic “Olin” has more pronounced meat qualities.

Positive Effect

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.

The effect of feed supplementing with glutamine, glucose and/or sodium butyrate was estimated on 156 piglets. The after-effect of supplements on fattener performance, carcass traits, and meat quality was examined. Piglets were allocated to 5 groups and fed standard feed mixture alone (control – C) or supplemented with 10 g of l-glutamine, or 10 g of glucose, or 3 g of sodium butyrate per kg of diet or all of these compounds (groups GT, GC, SB, and GT+GC+SB, respectively). Six piglets from each group were slaughtered at 63 days of age, their intestines were prepared and their parts measured. Digesta from ileum and caecum was taken for analysis. Its acidity and volatile fatty acids content were evaluated. Morphological structure of duodenal and ileal epithelium was estimated. After 84 days of age 20 animals from each group were fed the standard mixture. After 100 days of fattening 8 pigs from each group were slaughtered, pH of meat was measured, and samples of the longissimus muscle were taken for analysis. Body weight gains of piglets fed diets supplemented with SB or all supplements were higher than those of controls. All supplements given together increased total intestinal weight and length. Epithelial villi in jejunum were the highest in piglets receiving all supplements. Their height in the duodenum ranged from 296 to 347 µm and in the jejunum they were higher: 336 – 424 μm. After 100 days of fattening body weight of all experimental animals was higher than that of control. There was no significant difference in carcass and meat quality. Sodium butyrate added to the diet improved piglet performance probably due to changes in intestine development and in intestinal epithelium structure. This positive effect was enhanced to some extent by the addition of glutamine or glucose.

Product Quality Improvement

Abstract Over recent years, the range of biologically active substances aimed at the productivity increase, animals preservation, feed use efficiency, product quality improvement and product safety has been significantly expanded. In this regard, the study of the effectiveness of hepatoprotective farm-produced feed additives in the diets of broiler chickens is of particular interest to science and practice. The broiler chickens pectoral muscles of the control group contained 68–0.08% of water, 32–0.06% of dry matter, 20.45–0.08% of protein, and 1.62–0.09% fat. In a comparative analysis of the obtained data, it may be concluded that the use of the feed additive Hepatron 85% as a hepatoprotector improves the detoxification ability of the liver and promotes the regeneration of the liver cells. Betaine as a lipotropic agent contributes to the fat oxidation, enhances appetite, and adds muscle mass. When determining the chemical composition of the muscles of the leg, thigh, body, wings and neck, it was established that the broiler chickens of the experimental group contained 70–0.07% of water, 30–0.05% of dry matter, 19.7±0.08% of protein and 2.11±0.09% of fat. Using the feed with the additive Hepatron 85% causes a 0.5% increase in protein and 0.18% increase in fat compared to the meat of the broiler chickens on general feed. Thus, the inclusion of the feed additive Hepatron 85% in the ration of broiler chickens instead of 50% of methionine and choline contributes to an increase in average daily gains and meat quality improvement in a number of indicators.

The aim of the study was to analyse the effect of selected feed additives (pro-, pre- and synbiotics) on the health of mink, morphometric parameters of their digestive tract, and microbiological identification of its contents. The observations were made on pastel mink assigned to the following dietary treatments: group I – standard farm feed without supplements, group II – probiotic-supplemented feed, group III – prebiotic-supplemented feed, and group IV – synbiotic-supplemented feed. The feed additives were found to affect the growth and weight gains of the mink. Body weight at winter fur priming ranged from 1.45 to 2.54 kg in females and from 2.70 to 4.20 kg in males. During the rearing period (weaning to slaughter), the highest weight gains were observed in the group receiving prebiotics – on average 760 g in females and 1970 g in males. Analysis of the morphometric parameters of the digestive tract showed highly significant differences between means for the groups, except for the weight of the lungs and spleen and the length of the stomach. The mean concentration of total bacteria in the intestinal contents was similar in groups II and III (8.5-9.4 x 104 CFU/g), higher in group IV, and highest in the control group (5.9 x 106 CFU/g). Among the bacteria identified, Corynebacterium was dominant in all groups. The total fungal count in the intestinal contents was lowest in the mink receiving prebiotics. The dominant fungi were Candida, particularly Candida glabrata. The proportion of fungi of this genus varied between groups from 84.5% to 89.5%. The other fungi identified in the digesta were Rhizopus spp. and Aspergillus spp.
