The Impact

Societal pressure to reduce enteric methane emissions from cattle continues to increase. The present study evaluated the efficacy of the commercial essential oil feed additive Agolin® Ruminant on reducing enteric gas emissions and improving milk parameters in dairy cattle. Twenty mid-lactation Holstein cows, blocked by parity and days in milk, were randomly assigned to a top dress treatment with Agolin or an un-supplemented control for a 56-day trial. Cows were group housed and individually fed twice daily. Enteric gas emissions, including methane, carbon dioxide, ammonia, and nitrous oxide, were sampled every 14 days for a 12 h period via head chambers connected to a mobile air quality laboratory. Cows supplemented with Agolin versus the control had less methane intensity (g/period/kg energy-corrected milk (ECM); p = 0.025). Ammonia was the most affected gas, with lower ammonia production (mg/period; p = 0.028), and ammonia intensity (mg/period/kg ECM; p = 0.011) in Agolin-fed versus control-fed cows. All cow performance variables, including dry matter intake, ECM, milk fat, milk protein, or feed efficiency were similar between treatments. Further research should evaluate how Agolin impacts ruminal flora, focusing on mechanistic impacts to fermentation.

Reasil® Humic Vet is a liquid water-soluble feed additive with complex action. The aim of our research was to study the effect of the liquid feed additive "Reasil® Humic Vet" on the productive qualities and the digestibility of nutrients in compound feed by laying hens. The drug was drunk for 14 days with a break between courses of 7 days at a dose of 0.25, 0.50 and 0.75 ml / 1 liter of water. The highest egg production was obtained in chickens, the second experimental group -84.69%. The weight of 1 egg in this group also turned out to be higher than -63, 10 g. All this led to an increase in the egg weight to 31.09 kg, while reducing feed costs to 2.17 kg. The digestibility of organic matter in the experimental groups was 75.45, 75.44 and 75.37%, which is significantly higher than in the control group by 0.66, 0, 67 and 0.59%, respectively (P <0.05). The drug used with a high degree of reliability stimulated an increase in the digestibility coefficients of protein, fat, fiber (P <0.01) in chickens from 1 and 2 experimental groups. Increasing the amount of the supplement to the maximum dose did not significantly affect protein digestibility. Fat, fiber and dry matter in general in the 3rd experimental group had digestibility coefficients, the difference of which with those of the control group was confirmed by biometric processing (P <0.05 and 0.01).

Taking into account the data on higher biological availability of chelate compounds of microelements in comparison with their inorganic salts, a liquid feed additive for cattle with the content of fat-soluble vitamins A, D, E and diacetophenonyl selenide (DAFS 25) in the form of stable microemulsion and chelates of manganese, iron, cobalt, and zinc was developed. The biochemical and physiologically antagonistic components of the additive are divided into two separate liquid mixtures for separate, alternating ingestion on white laboratory mice, histological methods evaluated the effect of different doses of the additive on the micro organization of the components of the stomach wall, small and large intestine in different terms of the experiment. The additive was introduced into animals individually daily per o s during one month in doses of 0.06, 0.12, 0.3, 0.6 and 1.2 g/kg. The control animals received an equivalent amount of physiological solution. The availability of trace elements of the developed product is estimated by analysis of blood serum on the zinc, iron, manganese, cobalt content by atomic-adsorption spectrometry. Examination bodies and blood for analysis were selected at the time of slaughter in accordance with generally accepted requirements. The dosage of the additive, which has the most effective influence on the growth of the concentration of injected micronutrients in the serum of mice in comparison with the control, was determined. It was found that the components of the additive have the most pronounced effect on zinc and iron content in the dose of 0.3 g/kg.

1,25 Dihydroxyvitamin D

Individual and combined effects of several isomers of retinoic acid (RA) and 1,25-dihydroxyvitamin D3 (1,25-(OH)2D3) on interferon-gamma (IFN-gamma) secretion by blood mononuclear leukocytes (MNL) from nulliparous and postparturient Holstein cattle were evaluated in vitro. In the first experiment, effects on incubation period (24 to 72 hours) and time of supplementation (0 to 32 hours) with all-trans, 9-cis, 13-cis-, and 9,13-dicis-RAs (0 to 100 nM) on IFN-gamma secretion by pokeweed mitogen (PWM)-stimulated (0 and 10 mug/ml) MNL from nulliparous cattle were evaluated. In the second experiment, MNL from postparturient cows (bled at 0, 2, 4, and 16 days postpartum) were stimulated with PWM (0 and 10 mug/ml) in the presence of RA isomers (9-cis- or 9,13-dicis-RA; 0 to 100 nM), 1,25-(OH)2D3 (0 to 100 nM), or with combinations of these metabolites. The results show that individual isomers of RA had no effect on IFN-gamma secretion by PWM-stimulated MNL from nulliparous or postparturient cows. Furthermore 1,25-dihydroxyvitamin D3 inhibited IFN-gamma secretion by MNL from nulliparous and postparturient dairy cows; however, the degree of inhibition was greater when 9-cis- and 9,13-dicis-RA were also present in the cultures. Finally mononuclear leukocytes from postparturient dairy cows produced substantially less IFN-gamma than did MNL from nulliparous cattle. It is concluded that retinoic acids individually did not affect the capacity of leukocytes from dairy cattle to secrete IFN-gamma. This result is in marked contrast to studies in monogastric species indicating that RAs inhibit IFN-gamma secretion by peripheral blood T cells. Inhibition of IFN-gamma secretion by 1,25-(OH)2D3 was potentiated by 9-cis- and 9,13-di-cis-retinoics acids, suggesting that an excess of dietary vitamins A and D may compromise further the naturally immunosuppressed postparturient dairy cow. Additional research is necessary to determine if the combined effects of these metabolites on IFN-gamma secretion represent an increased susceptibility of the dairy cow to infectious diseases during the periparturient period. Lower secretion of IFN-gamma by MNL from postpartutient dairy cows, relative to nulliparous cattle, suggests that recently-calved cows are naturally immunosuppressed.
