The aim of this study is to evaluate the physical, nutritional, and sensory properties of cheese obtained from goats fed a dietary supplementation with olive leaves (OL). Thirty Saanen goats were randomly allocated into two groups of 15 goats each, (1) a control group fed with a standard diet (CG), and (2) an experimental group (EG) fed an OL-enriched diet. The trial lasted for 30 days. The milk of each group was then collected and used to produce Caciotta cheese, which was analyzed at the beginning and at the end of the ripening period (60 days). The results showed a positive effect of dietary OL supplementation in improving the fatty acid profiles due to the significant increase of unsaturated fatty acids, mostly α-linolenic acid (C18:3 n-3), with the consequent reduction of the ω-6/ω-3 ratio, a condition commonly associated with an increased health functionality of food products. Moreover, improved oxidative stability was observed in cheese during ripening, a presumable consequence of the transfer into the milk of dietary bioactive compounds, mainly polyphenols of high biological value, and credited as a marked antioxidant potential. Furthermore, reduced lipolytic action was observed in 60-day ripened cheese, even if no significant changes in sensory properties were evidenced.

Β Carotene

Recent evidences suggest that gut microbiota plays an important role in regulating physiological and metabolic activities of pregnant sows, and β-carotene has a potentially positive effect on reproduction, but the impact of β-carotene on gut microbiota in pregnant sows remains unknown. This study aimed to explore the effect and mechanisms of β-carotene on the reproductive performance of sows from the aspect of gut microbiota. A total of 48 hybrid pregnant sows (Landrace × Yorkshire) with similar parity were randomly allocated into three groups (n = 16) and fed with a basal diet or a diet containing 30 or 90 mg/kg of β-carotene from day 90 of gestation until parturition. Dietary supplementation of 30 or 90 mg/kg β-carotene increased the number of live birth to 11.82 ± 1.54 and 12.29 ± 2.09, respectively, while the control group was 11.00 ± 1.41 (P = 0.201). Moreover, β-carotene increased significantly the serum nitric oxide (NO) level and glutathione peroxidase (GSH-Px) activity (P < 0.05). Characterization of fecal microbiota revealed that 90 mg/kg β-carotene increased the diversity of the gut flora (P < 0.05). In particular, β-carotene decreased the relative abundance of Firmicutes including Lachnospiraceae AC2044 group, Lachnospiraceae NK4B4 group and Ruminococcaceae UCG-008, but enriched Proteobacteria including Bilophila and Sutterella, and Actinobacteria including Corynebacterium and Corynebacterium 1 which are related to NO synthesis. These data demonstrated that dietary supplementation of β-carotene may increase antioxidant enzyme activity and NO, an important vasodilator to promote the neonatal blood circulation, through regulating gut microbiota in sows.

The work aims to study the effect of different doses of the experimental probiotic preparation “Plantarum” when fed to pregnant animals on their reproductive qualities, as well as on the growth and development of young animals. To obtain young animals, four groups of goats were formed in the type of the Saanen breed, 20 heads each. In the first (control) group, the animals received a standard diet, in the diet of the animals of the second, third and fourth groups in the second half of pregnancy, the probiotic preparation “Plantarum” was additionally introduced, containing Lactobacillus Plantarum, Propiobacterium freudenreihii, in dosages from 0.4 to 0.8 ml/kg of body weight per day. From the offspring of the goats of the experimental groups, four groups of 12 goats were formed. The highest percentage of preservation (94%) and the highest business output of kids per 100 queens (150%) were observed in the fourth experimental group (0.8 ml). The goats of the second, third and fourth groups exceeded the body weight of their contemporaries from the control group by 3%, 6.3%, and 8.8%. The highest indices of the absolute increase in body weight by age periods were noted in the fourth group of goats. There were no significant differences in body build indices during the experiment between the goats of the control and experimental groups. Thus, the maximum positive effect was observed with the introduction of a probiotic preparation into the diet of pregnant goats at a dose of 0.8 ml/kg of body weight per day.

AbstractThe study aimed to determine the effect of three different levels of Boswellia serrata resin added to broiler diets on the fundamental production parameters, dry matter digestibility, organic matter digestibility, energy digestibility, microbiological condition of the gastrointestinal tract, and histomorphology of the walls of the small intestine. Two hundred Ross 308 chicks were assigned into 4 groups (50 birds of equal body weight) in 5 replications of 10 chicks each (5 females and 5 males). The experiment lasted 6 weeks. The control group (B0) was fed a standard mixture, without supplementation, whereas in groups B1.5, B2, and B2.5, the Boswellia serrata resin was added at the levels of 1.5, 2.0, and 2.5% of the complete feed mixture, respectively. The dietary supplementation with 2.0 and 2.5% of Boswellia serrata resin contributed to a significant increase in the length of the duodenum and total intestine and in the digestibility of dry matter and organic matter in feed. In these groups, the values of FCR and EEI were positively influenced (P<0.05) and an improvement in the structure of the jejunal wall was also recorded (P<0.05). An increase in the count of Lactobacillus and Enterococcus in the intestinal contents in broilers fed with the Boswellia serrata resin supplemented diets was observed. In conclusion, the Boswellia serrata resin can be considered as an effective feed additive, which stimulates production and has a positive effect on intestinal microflora and morphology of broilers.

The effect of dietary supplementation with vitamin E, oregano, and prebiotic on fatty acids and oxidative profiles of rabbit meat (loin and hind leg) was evaluated. New Zealand white rabbits weaned at 30 days of age were fed with one of six diets until 80 days of age: standard diet includingω3 polyunsaturated fatty and conjugated linolenic acids sources (S) and five diets adding vitamin E (150 ppm, E), oregano water extract (2 g/kg feed diet, O), prebiotic (THEPAX® 1.5 g/kg feed diet, T), vitamin E plus prebiotic (TE), and oregano water extract plus prebiotic (TO), respectively. The lipid oxidative status (TBARS) showed lower values with respect to S, mainly when vitamin E was administered. In particular, all the experimental diets decreased TBARS values with respect to the control group in the loin, but no effect was found in the hind leg. In all feed samples, the amounts of fatty acid classes increased in the following order: polyunsaturated fatty acids > monounsaturated fatty acid > saturated fatty acid. The dietary supplementations did not affect the fatty acid composition of meat. The experimented diets compared to the control were not able to provide a selective increase of bioactive fatty acid in meat samples; however, the six nutritional strategies led to highly nutritional rabbit meat with an interesting value of theω6/ω3 ratio.

Olive Leaves

The aim of this study was to evaluate the development of volatile compounds in yogurt samples obtained from goats fed a dietary supplementation with olive leaves (OL). For this purpose, thirty Saanen goats were divided into two homogeneous groups of 15 goats each: a control group that received a standard diet (CG) and an experimental group whose diet was supplemented with olive leaves (OLG). The trial lasted 28 days, at the end of which the milk of each group was collected and used for yogurt production. Immediately after production, and after 7 days of storage at 4 °C in the absence of light, the yogurt samples were characterized in terms of fatty acid profile, oxidative stability and volatile compounds by the solid-phase microextraction (SPME)–GC/MS technique. Dietary OL supplementation positively affected the fatty acid composition, inducing a significant increase in the relative proportion of unsaturated fatty acids, mainly oleic acid (C18:1 cis9) and linolenic acid (C18:3). With regard to the volatile profile, both in fresh and yogurt samples stored for 7 days, the OL supplementation induced an increase in free fatty acids, probably due to an increase in lipolysis carried out by microbial and endogenous milk enzymes. Specifically, the largest variations were found for C6, C7, C8 and C10 free fatty acids. In the same samples, a significant decrease in aldehydes, mainly heptanal and nonanal, was also detected, supporting—at least in part—an improvement in the oxidative stability. Moreover, alcohols, esters and ketones appeared lower in OLG samples, while no significant variations were observed for lactones. These findings suggest the positive role of dietary OL supplementation in the production of goats’ milk yogurt, with characteristics potentially indicative of an improvement in nutritional properties and flavor.

The aim of this study was to evaluate the effect of dietary supplementation with dried grape pomace on beef quality. Ten Friesian calves were divided into two groups, a control group that received a standard diet, and an experimental group that was administered the dietary supplementation. At the end of the 75 days of the trial, animals were slaughtered, and meat samples analyzed for physical and chemical properties, fatty acids composition, lipid oxidation, volatile compounds, and biogenic amines. The fatty acid profile resulted affected by dietary supplementation, since an increase in concentration of linoleic acid was observed. Furthermore, a reduction of lipid oxidation was found in the same samples. With reference to volatile compounds a reduction of hexanal and an increase of 2‐3 octanedione was evidenced, while no effects were induced by diets on the synthesis of biogenic amines. The grape pomace exploitation as a dietary supplement in bovine diet did not have negative effects on the quality of beef and showed the potential to extend shelf life due to marked improvement in oxidative stability. Overall, the present study showed a viable way for the recovery and the valorization of the main by-product of the oenological industry.

β-glucans have been shown to stimulate the immune system in several animal species. The aim of this study was to evaluate the immune stimulation capacity of a fully formulated diet with β-1,3-1,6-glucans in cats, by assessing the rabies antibody titer after vaccination. Thirty-five healthy cats were recruited. The cats were placed into two groups and fed a standard diet in accordance with body weight. One group had the β-glucans incorporated into the diet; the other group served as the control group. After two weeks of dietary adjustment; the rabies vaccine (Imrab® 3 TF; Merial) was administered on days 0 and 21. Blood samples were taken on days 0, 21, and 42. Titers were determined with the rapid fluorescent foci inhibition test (RFFIT). Titers at days 21 and 42 were compared between the two groups in a linear mixed effects model. This study showed that the animals receiving the non-supplemented feed had higher post-vaccination rabies antibody titers. This indicates that, in contrast to other animal species, the β-glucan supplemented diet did not have the expected positive effect on the rabies antibody titers in cats.

Introduction. Dry fermented meat products are considered to be fine foods. Their quality depends on a combination of various processes. The composition and properties of raw materials, e.g. fat, play a key role in quality formation. The research objective was to study the fermentation process in fourth-category pork obtained from sows, which contains a lot of highly unsaturated fatty acids. The considerable resources that this raw material can provide require improved technologies. Study objects and methods. The research featured two types of pork. The first group included samples made from fourth-category carcasses, i.e. hip muscle tissue and spine fat, in the ratio of 85:15. The second group included control samples made from secondcategory pork that was obtained from young animals. This type of meat is traditionally used for fermented products. The fermentation process was performed using starter cultures for rapid fermentation of StLb 37.03 M (0.1% by weight of raw materials). The samples were fermented at the activation temperatures of the starter cultures for 48 h. After that, the samples were dried at 50°C with shortterm smoke supply for 1 h. The total time of the production cycle was 14 days. The samples were monitored for water activity, pH, weight loss, chemical composition, amount of free fatty acids, secondary and primary oxidation products, color characteristics, and sensory properties during all stages of the process. Results and discussion. The content of unsaturated fatty acids was 65.39% of the total amount of fatty acids in the fourth-category pork obtained from sows. In the second-category pork obtained from young animals, it was 59.1%. Water activity, pH, and moistureprotein ratio were within the control criteria for shelf stable products. The analysis of thiobarbituric values and free fatty acids indicated a deeper degradation of the fat part, but their values were comparable to those of the control group. The sensory properties of fourth-category fermented pork were highly evaluated by experts. Conclusion. The obtained data proved the possibility of using fourth-category raw materials in the technology of fermented delicatessen products.

Цель исследования изучение биохимического статуса организма телят 1 3месячного возраста при применении вермикулита. Опыт на животных проводили в течение 60 дней. Для опыта были отобраны, по принципу аналогов, 3 группы телят молочного периода выращивания по 9 голов в каждой. Телята контрольной группы получали стандартный рацион, телятам 1й опытной группы к основному рациону добавляли 2 на голову в сутки вермикулита, 2й опытной группе 3 на голову в сутки. Использовали вермикулит (ГОСТ 1286567), выпускаемый ОАО Ковдорслюда . Для изучения состояния обменных процессов в организме подопытных животных отбирали кровь из яремной вены после утреннего кормления два раза: в начале опыта и через месяц после его окончания. Исследования показали, что использование вермикулита в кормлении молочных телят, благодаря многогранным буферным, ионообменным и сорбционным свойствам положительно сказалось на белковоминеральном обмене животных и интенсивности их роста. В опытных группах уровень общего белка вырос в 1,04 1,06 раза, достоверно повысился к концу исследований уровень альбуминов. Целесообразно для нормализации обменных процессов в организме молочных телят использовать добавку вермикулита в количестве 2 и 3 к сухому веществу рациона.The purpose of the research is to study the biochemical status of the organism of calves 13 months of age with the use of vermiculite. The animal experiment was carried out for 60 days. 3 groups of calves of the dairy period of growing of 9 animals in each were selected for the experiment according to the principle of analogues. The calves of the control group received a standard diet, 2 per head per day of vermiculite was added to the main diet of the calves of the 1st experimental group, and the 2nd experimental group 3 per head per day. We used vermiculite (GOST 1286567) manufactured by OAO Kovdorslyuda. To study the state of metabolic processes in the body of experimental animals blood was taken from the jugular vein after morning feeding two times: at the beginning of the experiment and one month after its completion. Researches have shown that the use of vermiculite in the feeding of dairy calves due to its multifaceted buffering, ionexchange and sorption properties has a positive effect on the proteinmineral metabolism of animals and their growth rate. In the experimental groups the level of total protein increased in 1.04 1.06 times and the level of albumen significantly increased by the end of the research. It is advisable to normalize the metabolic processes in the body of dairy calves to use the additive of vermiculite in an amount of 2 and 3 to the dry matter of the diet.

This article presents material on the study of the efficiency of raising Edilbayev sheep using a new feed supplement and assesses its effect on increasing the meat productivity of animals and improving mutton indices. To do this, we at Volgograd-Edilbay SGC LLC selected 30 animals of the Edilbayev breed of 7 months of age in two experimental groups according to the principle of pair-analogues with 15 animals each. The rams who received the standard diet were included in the control group, and their analogues, which were introduced a new feed additive in the diet, were included in the experimental group. The duration of the experiment was 105 days. In this case, the preparatory period of the experiment is 10 days, the transitional period is 5 days, the main one is 90 days. As a result of the experiment, it was found that at the end of the experiment, the rams of the experimental group exceeded their counterparts in the control group in live weight by 2.9 kg, or 5.72% (P≥0.999). As a result of the control slaughter, it was established that by the pre-slaughter mass, the rams of the experimental group are 1.65 kg or 3.35% more than analogues of the control group (P≥0.95); weight of fat tail fat - by 0.35 kg, or 13.21%; slaughter mass - by 1.49 kg, or 5.23% (P≥0.99); slaughter yield - by 1.09%, respectively. A study of the chemical composition of lamb showed that in the content of the rams of the experimental group in the meat, iodine was 0.08 μg / g more than the analogues of the control group (P≥0.95); silicon - at 3.92 μg / g; selenium - at 0.12 μg / g (P≥0.99); zinc - at 6.0 μg / g, respectively. According to the content of fatty acids, tail fat obtained from animals of the control and experimental groups differs in favor of the experimental group. Saturated fatty acids in turkey fat of animals from the experimental group contain 61.34%, which is 3.22% higher in comparison with the control group. Unsaturated fatty acids in animals of the experimental group contain 38.66%, which is 3.17% less in comparison with the control group. Thus, the highest results in meat productivity, chemical composition, and the amount of saturated and unsaturated acids were obtained from edilbaevsky rams that received a new feed supplement.
