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

Abstract Background The excessive use of antibiotics in the livestock feed industry caused inevitable side effects of microbial resistance. Besides this residual antibiotics in animal-derived foodstuff imposed serious health problems for humans. So this study aimed to investigate the potential use of Bacillus velezensis to substitute antibiotics for poultry production. A total of 468, 49-week-old Hy-Line Brown chickens, were randomly divided into four groups the control group (regular diet), experiment group I (0.1% B. veleznesis), experiment group II (0.2% B. veleznesis), and antibiotic group (50 mg/kg flavomycin), with three replicates per group and trial period consisted on 42 days. Results The results showed that, compared with the control group, the average egg production rate and daily feed intake of experimental groups I and II increased significantly (P < 0.05), while the average egg weight was increased in experimental group II as compared to (I) (P < 0.01). The feed conversion ratio was decreased (P > 0.05) in group (II) Egg quality parameters such as yolk weight of the experimental group II was increased, but that of the antibiotic group and experiment group I was decreased, neither significant (P > 0.05). Moreover, the eggshell strength, yolk color, albumen height, and Haugh unit were significantly increased (P < 0.05). Compared with the control group, probiotic groups can increase the progesterone and motilin (P > 0.05) but decrease the secretin and cholecystokinin in the blood plasma (P > 0.05). Conclusions This study suggested that B. velezensis can substitute in-feed-antibiotics and improved most of the study parameters significantly. Which suggested that B. velezensis has potential future application value to replace the feed antibiotics.

The study was conducted to determine the effects of vitamin E on reproductive performance in mice treated with 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). The 75 female and 40 male mice were randomly assigned into five groups. The levels of both TCDD and vitamin E given by gavage were 0 and 0 (Control group), 100 and 0 (experimental group I), 100 and 20 (experimental group II), 100 and 100 (experimental group III), and 100 ng/kg/day and 500 mg/kg/day (experimental group IV), respectively. Males and females were mixed to mate at the ratio of 1:2 after 4-week experiment. The gavage treatments were continued until the end of gestation in female mice after mating. The results showed that the litter number, survival rate, and body weight at birth of offspring in experimental group I had significantly decreased, and the females’ pregnancy rate and pup sex ratio in experimental group I had the decreasing tendencies when compared with the control group. The litter number in experimental group III, survival rate in experimental group II and III, body weight at birth in experimental group III and IV exhibited significant increase compared with experimental group I. The female pregnancy rate in both experimental group III and IV recovered to 100%, but there were no significant differences when compared with experimental group I. The pups’ sex ratio had a gradually increasing tendency with increase of vitamin E level, but there was no significant difference among experimental group I–IV. The results suggest that TCDD could induce reproductive toxicity in mice, whereas vitamin E alleviated adverse effects on reproductive performance in mice caused by TCDD.

The influence of feeding high-performance cows of the energy feed additive Cobiotic Energy on the physiological state and productivity have been studied. Experiments have been carried out on with groups of dairy cows with 10 animals each during 55 days. The diet of cows of the first control group consisted of haylage of cereal and leguminous plants, corn silage, molasses, cereal hay, and feed of own production. 0.3 kg of feed additive has been introduced into the diet of animals of the experimental group II 15 days before calving, in the first 10 days after calving, as compensation for energy losses, 0.75 kg 3 times a day. In the next 30 days of the milking season with the ration of animals of the experimental group II, 0.25 kg of Cobiotic Energy has been fed, sprinkling it on top of the feed mixture. It has been established that the use of feed additives in the diets of cows has a positive effect on feed intake, physiological condition and animal productivity. It was determined that concentration of metabolizable energy in 1 kg of dry matter of the diet made 9–16– 9.2 MJ. The diet contained 12.8–13.0 % of crude protein per 1 kg of dry matter, the concentration of fiber in dry matter made 22.3– 22.0 %. The sugar-protein ratio made 1.04:1; 1.0. In terms of energy nutrition, the diet of the experimental group due to the inclusion of the feed supplement was 6 MJ higher, however, it slightly affected concentration of metabolizable energy of the diet. The energy-protein ratio corresponded to 0.2– 0.21. The nitrogen balance in the rumen was positive in all the animals and was at the level of 0.13–0.4 g. Feeding animals with supplement in the diet in the last 15 days of the dry period, during the first 10 days after calving and the next 30 days of the milking period promoted activation of protein biosynthesis and energy metabolism, as evidenced by an increase in serum total protein and its albumin fraction and ultimately increased animal productivity. The studied supplement use in the diets for cows makes it possible to increase performance of cows by 8.0 %, fat content by 0.1 %, protein by 0.24 %, lactose by 0.11 %, reduce the cost of feed for obtaining natural milk by 6.1%. Key words: feed supplement Cobiotic Energy, cows, diets, blood, milk yield, feed costs, milk quality.

Introduction. Nutrition has a great effect on the quality of life and longevity. Modern food industry pays much attention to the issue of obtaining high-quality and safe livestock products grown without feed antibiotics. The research objective was to study the effect of chamomile extract on a complex of economically useful traits of young rabbits and the qualitative characteristics of meat, as well as to determine the optimal dosage of chamomile extract. Study objects and methods. The experimental research was carried out on the animal farm of the Kuzbass State Agricultural Academy in 2018. Five experimental groups and one control group of young Californian rabbits were formed according to the principle of analogue pairs. Each group included 10 rabbits. From 70-day age, the animals of the experimental group I were supplemented with a phytobiotic feed additive based on wild chamomile extract at a dose of 0.5 g per rabbit per day. In experimental group II, each rabbit received 1 g per day; in experimental group III, it was 1.5 g per rabbit per day; in experimental group IV – 2.0 g per rabbit per day; in experimental group V – 2.5 g per head per day. The experiment lasted 30 days. Results and discussion. The best result was achieved in experimental group II. In the experimental groups, the rabbits demonstrated an increase in hemoglobin. The use of phytobiotic feed additives in the diet did not cause any pathological changes in internal organs. The average live weight at the end of the experiment, compared with the control group, was higher: experimental group I – by 0.82%, experimental group II – by 6.96%, experimental group III – by 5.01%, experimental group IV – by 3.73%, experimental group V – by 2.80% (P ˃ 0.01). An analysis of the chemical composition of rabbit meat after the experiment showed that the water content in the rabbit meat ranged from 76 to 77%, which suggests high water-holding properties. The high dietary qualities of the rabbit meat depended on the content of protein (20–22 wt%) and the low fat content (5–7%). These data make it possible to promote rabbit meat for dietary products. Conclusion. According to the slaughter indicators and the phytobiotic feed additives parameters of meat, the optimal dose of phytobiotic feed additives is 1 g per head per day.

The study was aimed to evaluate the effect of sunlight on vitamin D and calcium status among the college girls, aged 18 – 22 years. One hundred and fifty girls were selected out of which 45 with vitamin D deficiency were considered for experiment. The participants were divided into three groups of 15 each: Experimental I - curd supplementation, exposure to sunlight and nutrition education; Experimental II - exposure to sunlight and nutrition education and Control group with no intervention. Anthropometric measurements, blood haemoglobin, serum vitamin D and calcium were analysed before and after supplementation for 50 days. In the experimental group I, there was a mean increase of 3.22 ng/ml of vitamin D and was significant at 1% level and in the experimental group II the increase was 1.03 ng/ml (significant at 5% level). There was a mean difference of 1.57 ng/ml in the control group which was not significant. The mean initial calcium level in the experimental group I was 9.33 mg/dl and the final value is 9.67 mg/dl and the increase was significant at 1% level. The experimental group II had a mean initial calcium level of 9.36 mg/dl and the mean final value of 9.56 ml g/dl. The mean difference of 0.05 mg/dl was noted in serum calcium before and after supplementation in the control group. The experimental group I showed a positive correlation of 0.035 between vitamin D and sunlight whereas in experimental group II and control group there was a negative correlation of 0.045 and 0.072 respectively. It can be concluded that sunlight had an effect on vitamin D status and the calcium level of the participants further highlighting that sunlight exposure is an effective method of improving the vitamin D status.

This study evaluated periodontal repair and biomaterial reaction following implantation of a newly fabricated calcium phosphate block bone with chitosan membrane on the regeneration of 1-wall intrabony defects in the beagle dogs. The surgical control group received a flap operation only, while the experimental group I was treated with a chitosan nonwoven membrane only and the experimental group II was treated with a chitosan nonwoven membrane and a calcium phosphate block bone. The subjects were sacrificed 12 weeks after surgery and a comparative histometric analysis was done. No root resorption or ankylosis were observed in the experimental group. Mann-Whitney U test showed that the experimental group II produced statistically significant higher gain in connective tissue adhesion, new cementum regeneration and new bone formation. Based on histological results, the calcium phosphate block bone successfully functioned as a osteoconductive scaffold for invading cells of host.

Abstract Objective: To examine the effects of gradually increasing force generated by permanent rare earth magnets for orthodontic tooth movement by using a novel experimental rat model and computer simulation. Materials and Methods: Fifty-five male rats (age 18 weeks) were used as animal experiments. Magnetic (experimental groups) or titanium (control group) cuboids (1.5 × 1.5 × 0.7 mm) were bonded to the lingual surface of the maxillary first molars. The initial distance between materials was 1.0 mm, generating 4.96 gf (experimental group I), or 1.5 mm, generating 2.26 gf (experimental group II). Tooth movement was measured and periodontal structures were observed with microfocus x-ray computed tomography radiographs. Results: The distance between the magnets decreased with time in experimental groups I and II (P &lt; .001), whereas there was no tooth displacement in the control group. Experimental group I showed rapid tooth movement in the initial phase followed by slower tooth movement. Experimental group II showed gradual tooth movement. Horizontal sections on microfocus computed tomgraphy radiographs revealed no pathological changes, such as root resorption, on the compressed side in the experimental groups. Conclusions: The initial light force and gradual increasing force in magnetic attractive force induced effective tooth movement in rats without inducing any pathological changes.
