The aim of this study was designed to examine the efficiency of various iodine compounds in pigs’ diets. The impact of inorganic and organic iodine compounds – potassium iodate and iodated milk protein, which is a part of the "ProstTM" feed additive ("Innbiotech", Russia) – on the growth, meat productivity and lean meat yield of fattening pigs was studied. The physico-chemical composition and biological value of the meat were studied. The accumulation of iodine in animal muscle tissue was assessed. It was found that iodized milk protein contributed to more intensive growth than the inorganic iodine source. Specifically, animals fed the organic form of iodine were superior in terms of carcass weight and yield value of muscle and fat tissue. Compared to the control group, the experimental groups of pigs demonstrated a muscle tissue yield of 0.45%. Organic sources of iodine were also found to have a positive impact on the chemical composition of meat; animals fed the organic form of iodine surpassed those receiving inorganic iodine in terms of their meat’s dry substance, protein content and fat content. The level of iodine in the muscle tissue of pigs receiving organic iodine was considerably higher, and these pigs surpassed those receiving the inorganic iodine source in terms of the presence of essential amino acids in their muscle tissue.

SummaryThe following trial was conducted to evaluate the impact of feeding Yea-Sacc® (YS; Alltech Inc, USA), a zootechnical feed additive based on a live probiotic strain of Saccharomyces cerevisiae, to lactating dairy cows over a 12 week period. Sixty-four primiparous and multiparous Holstein dairy cows, grouped to give similar range of parity, physiological and milk production stages, were selected for the study. Cows were equally allocated to either a control feed group or a diet supplemented with YS (32 cows per treatment). The test diet was formulated to include YS (Yea-Sacc® Farm Pak) incorporated in the total mixed ration (TMR), supplying a target dose of 5 × 107 CFU/kg feed dry matter (DM). This target dose delivered 1 × 109 CFU/cow/day, for a cow consuming 20 kg feed (DM basis) daily. Each cow was considered a replicate unit. Cows were fed a nutritionally adequate total TMR plus hay and a supplementary protein/energy concentrate (calculated according to milk yield) for 12 weeks, supplied once a day after the morning milking. Weigh backs of feed were recorded daily, with refusals being maintained at 3% of the total intake. During the 12 week study period, YS had significant beneficial effects on milk production (+0.8 kg/day; P = 0.003), energy corrected milk production (+1.4 kg/day; P < 0.0001), synthesis of milk protein (+36 g/day; P = 0.001), milk protein content (+0.3 g/kg; P = 0.009), and milk urea content (−0.09 mg/l; P = 0.004). The synthesis of milk fat was similar between treatments but milk fat content was lower for the YS group compared to the control group (−1.1 g/kg; P = 0.0002). Lactose content was always higher (+0.8 g/kg; P < 0.0001) for the YS group, indicating enhanced energy utilisation. In general, the effect of YS was higher during the first study period (one to seven weeks), when cows were in early lactation and the production potential was higher. YS cows produced significantly more milk during the study, and an additional 220 kg milk per cow was sold from this group from the output measured from the beginning of the study to two weeks post-trial. However, the statistical analysis including the post-study period did not show a significant effect. The 305-day simulated milk production was higher for the YS group (+400 kg/cow) but again the difference was not significant. In conclusion, YS at a target dose of 5 × 107 CFU/kg DM improved milk production and milk quality in healthy dairy cows. In addition, when the data were included in a whole-farm model, feeding YS reduced methane emissions by 4%, reduced the number of animals required for the desired milk production by 4% and increased overall farm margins by 1.4%.

Introduction. One of the ways to the solve iodine deficiency problem is the addition of iodine to farm animal feed. It allows producing iodized livestock products. Promising sources of organic iodine are iodotyrosine-containing iodized milk proteins. Organic iodine accumulation in organs and tissues has not been sufficiently studied. Study objects and methods. We determined iodotyrosine content in rat blood plasma and in pig muscle tissue. For this purpose, high performance liquid chromatography with mass spectrometric detection and cathodic stripping voltammetry were used. Results and discussion. At the first stage of the study, we examined iodotyrosines in rat blood plasma after a single administration of iodized milk protein or potassium iodide (30 μg I/kg weight) at specific time intervals. A significant increase in the concentration of monoiodotyrosine and diiodotyrosine was recorded 4 and 24 h after the administration. At the second stage, we studied the accumulation of iodotyrosines in the muscle tissue of pigs during their fattening period (104 days). The diet of the control animal group included potassium iodide (0.6 mg I/kg of feed). The experimental groups A and B got iodized milk protein (0.3 and 0.6 mg I/kg of feed, respectively). Monoiodotyrosin content in the muscle tissue of pigs of the experimental groups was 3.0 and 5.2 times higher than that in the control group. Diiodotyrosine content was 4.9 and 8.2 times higher. In the experimental group A, iodine content in muscle tissues was 26% higher than that in the control group, in the experimental group B it was 72% higher. Calculations of iodine intake balance and its accumulation in muscle tissues showed that in animals whose diet included iodized milk protein, the iodine assimilation was much higher (0.70 and 0.53%) than in the control group (0.21%). Conclusion. Iodotyrosines from iodized milk protein are absorbed by the gastrointestinal tract in an unchanged form and accumulate in muscle tissues. The findings give more clear understanding of physiological and biochemical mechanisms of organic iodine absorption in animals.

The production of ecologically clean fish products is in demand in the food market. As a result of the research, the nutritional quality and chemical composition of the muscle tissue of the Nile tilapia (Oreochromis niloticus L.) were evaluated using the pro-biotic additive Enzimsporin. A valuable quality of Nile tilapia meat is its high protein content. In the muscle tissue, the maximum amount of protein was 80.4%, in the yearlings of the 1st experimental group, which is 7.51% (P ≥ 0.99) higher than in the control group. Yearlings of the 2nd experimental group outperformed their peers from the control group by 4.8% (P ≥ 0.95). Its amount in fry of Nile tilapia varied from 72.27–72.73% in the experimental groups to 74.71% in the control group. The fat content in fry varied from 9.55% in the control to 12.19% in the fish of the 2nd experimental group. The amount of lipids was the highest in the control variant of Nile tilapia yearlings (11.48%), which is 6.48% more than in the 1st experimental group and by 4.48% more than that in the 2nd experimental group. The lipid-protein coefficient (0.06-0.09) of the experimental groups characterizes the meat as less tender, but high in protein, possessing lipotropic properties that protect the liver from fatty infiltration. The study of nutritional value and functional and technological properties shows that tilapia meat can be attributed to highly saturated food raw materials and used to obtain dietary products.

Non-alcoholic fatty liver disease (NAFLD) has become of major interest worldwide, it is estimated that more than 20% of the general population suffer from liver steatosis. NAFLD is highly associated with metabolic risk factors like type 2 diabetes mellitus, obesity and dyslipidemia, the patients diagnosed with NAFLD should adopt a high fiber low calorie diet, with reduced saturated fat and carbohydrates content, leading to weight loss and improvement of metabolic profile. Our study is aiming to shape the profile of the patient interested in being informed related to food quality and chemical composition and to evaluate the aspects on the food products label which are important for the customer. Between June 2017 and December 2017, 83 patients diagnosed with NASH were included in the study, representing the study group, while 33 subjects, without metabolic syndrome or digestive diseases, selected from patient list belonging to two general practitioners, constituted the control group. Related to the interest of being informed about the chemical composition and nutritional value of the products bought, the study showed a low interest for the provided information on nutritional value. lack of confidence in the provided information and complexity of the information are understandable, the high number of subject reasoning through lack of immediate clinical benefit is surprising. Among the healthy population the willingness to pay attention to this aspect is extremely low.

In our experiment with 20 mares (3.6–19.8 years old) divided into 3 groups we evaluated the effect of supplementation with various sources of copper on the trace elements profile in the hair, blood plasma and faeces and copper activity in the organism of horses. The horses were stabled in box stalls (similar dimension) with feeding pump, with the access to a paddock or walker. All mares received the same basic feed ration that was supplemented with various form of copper (Cu in the organic form – proteinate - Bioplex Cu vs. Cu in the inorganic form – CuSO4.5H2O) in amount of 120 mg per day for the mares in experimental groups. The contents of trace elements in hair and faeces were established using the atomic absorption spectrometry; in the plasma using direct colorimetric determination.Significant difference between mares receiving copper in organic and inorganic form (P < 0.05) was detected in the blood levels of copper and iron. In both experimental groups a supplement of copper increased its level in the hair as compared to the control group; however this increase was statistically significant (P < 0.01) only if the inorganic form of copper was supplemented. The iron content of mares hair apparently varied not only with minerals intake, but also with the condition of kept. The differences of copper concentration in the faeces among the mares of experimental groups with regard to control group were significant (P < 0.01). An excessive amount of copper evidently reduced the absorption of zinc and iron in mares with addition of copper sulphate.The mares receiving Bioplex-Cu excreted lower amount of copper in the faeces. These had well-balanced levels of Cu in the plasma and deposited less Cu in the hair than the mares with addition of copper sulphate. In our experiment, it seems to be better available copper in the organic form than in the inorganic form for the organism of horses.Nevertheless, interpretation of these results is very difficult. Evaluation the impact of various sources of copper on the elements profile; assessed using skin derivates, plasma or other parameters should be subjected to further observation.

The flavonoids were extracted from alfalfa using ethanol assisted with ultrasonic extraction and purified by D101 macroporous resin column chromatography. The chemical composition and content of ethanol elution fractions (EEFs) were assessed by ultrahigh-performance liquid chromatography and hybrid quadrupole time of flight mass spectrometry (UHPLC-Q-TOF-MS) and aluminum nitrate-sodium nitrite-sodium hydroxide colorimetric method. The in vitro antioxidant activity of two EEFs was conducted by scavenging DPPH free radical, and the main antioxidants of 75% EEFs were screened using DPPH-UHPLC. Moreover, the in vivo antioxidant activity of 75% EEFs and the growth performance of broilers were studied. The results showed that the content of 30% and 75% EEFs was 26.20% and 62.57%. Fifteen compounds were identified from 75% EEFs, and five of them were reported in alfalfa for the first time. The scavenging activity of 75% and 30% EEFs (200 μg/mL) against DPPH was 95.51% and 78.85%. The peak area of 5,3′,4′-trihydroxyflavone and hyperoside was decreased by 82.69% and 76.04%, which exhibited strong scavenging capacities. The total antioxidant capacity (T-AOC), superoxide dismutase (SOD), and glutathione peroxidase (GSH-PX) level of three treated groups against the normal control group (NC) fed with basal diet significantly increased by 3.89-24.49%, 0.53-7.39%, and 0.79-11.79%, respectively. While the malondialdehyde (MDA) decreased by 0.47-18.27%. Compared with the NC, the feed to gain ratio (F : G) of three treated groups was lowered by 2.98-16.53% and survival rate of broilers significantly increased. Consequently, 75% EEFs extracted from alfalfa exhibited powerful antioxidant activities and might be a potential feed additive to poultry and livestock.

The effectiveness of the biogenic stimulants action based on the larvae of the SITR bees drone brood and adult individuals of the ST drones on the chemical composition, physical and chemical, commodity technological properties, nutritional and biological value of the muscle and fatty tissues in young turkeys is studied. The turkey-poults of the 1st group received injections of a physiological salt solution, and the 2nd and 3rd experimental groups, respectively, of the SITR and ST biological stimulants, three times at the age of 1, 7 and 14 days at a dose of 0.1 ml per 50 g of live weight. It was established that in the middle sample of the muscle tissue in turkeys of the 2nd and 3rd experimental groups there were less water and more dry matter and protein. Biogenic stimulants contributed to the synthesis of muscle tissue in turkeys of the 2nd and 3rd experimental groups, in which contained 1.79 (B>0.999) and 1.31 (B>0.99) absolute % more protein and 0.32 and 0.23 absolute % less fat than in the control group. In the muscle tissue of turkeys stimulated with biogenic preparations, there were more tryptophan by 1.63 and 0.84 mg% and by 0.92 and 0.54 mg% less hydroxyproline than in turkeys at the same age of the control group. The protein-quality index of muscle tissue was higher in turkeys of the 2nd and 3rd experimental groups by 3.08 and 1.72% than in the control. The first place in the overall assessment of meat and broth quality was taken by the turkeys from the 2nd experimental group; the second place was taken by the turkeys of the third experimental group. Their superiority over the control group was 0.151 and 0.109 points, respectively. The fatty tissue of turkeys in all experimental groups has good quality and high digestibility indices. It has in its composition a large amount of polyunsaturated fatty acids; this indicates its high biological value.

Наведені результати відгодівлі свиней полтавськоїм’ясної породи з використанням соєвих кормів, виго-товлених за різними технологіями (експандування підтиском, віджим під пресом, екструзія) та вплив да-них білкових кормів на хімічний склад і міцність стег-нових кісток. Більш продуктивними виявилися під-свинки, яких годували соєвим концентратом (групаД1), соєвою макухою (група Д2) та соєвим екстру-датом (група Д3). На відгодівлі вони показали серед-ньодобові прирости 825–833–785 г відповідно, і ви-тратили на 1 кг приросту 3,26–3,47 кормових оди-ниць. У їх стегнових кістках було більше кальцію на1,66–1,04–2,78 % і фосфору на 0,67–0,53–0,38 %, ніжу кістках тварин контрольної групи. Підсвинки до-слідних груп мали дещо менший діаметр кістки на0,51–0,33–0,73 мм, але більшу товщину кістковоїстінки (крім групи Д2) на 0,35–0,24 мм. Найбільшенавантаження на весь діаметр кістки зафіксовано удослідній групі Д3. The results of pigs’ fattening of Poltava meat breed using soy feed, which made by different technologies (expundation under pressure, spin under pressure, extrusion) and the impact of these protein feeds on the chemical composition and strength of the femoral bone. More productive pigs were fed soy concentrate (Group R1), soybean oilcake (group R2) and soy extrudate (group R3). In feeding they showed average growth 825–833–785 g, and spent 3,26–3,47 feed units for 1 kg of growth. Their femoral bone had more calcium to 1,66–1,04–2,78 % and phosphorus to 0,67–0,53–0,38 % than the bones of animals in the control group. Piglets of the research groups had smaller diameter of bone to 0,51–0,33–0,73 mm, but thicker thickness of bone’s wall (except group R2) to 0,35–0,24 mm. The maximum load for the entire diameter of the bone observed in the experimental group R3.

AbstractThe aim of the study was to perform feeding experiments on growing pigs in order to assess the impact of macroalga Enteromorpha sp. enriched with Zn(II) and Cu(II) ions via the biosorption process on the mineral composition of blood, meat, liver, feces and urine. In the control group, microelements were supplemented as inorganic salts, whereas in the experimental groups they were replaced by enriched macroalga. After 3 months of the feeding experiment, it was found that the meat was biofortified with Cr, Mn, Fe, Cu and Zn. The average content of Zn in the blood from the pigs fed with algae was higher by 9.5%, compared to that in the blood from pigs in the control group. The liver of growing pigs from the experimental group contained 16% less Cu and 18% less Zn than the liver in the control group. Growing pigs fed with macroalgae excreted in feces 27% more Zn than growing pigs in the control group, but 3.5 times less Cu. It could be concluded that the bioavailability of microelements to pigs from algae was higher than from the inorganic salts. Baltic macroalgae enriched with microelement ions could be potentially used as a biological feed additive.
