Effect of fumaric and lactic acids on meat productivity of young cattle

Abstract

Purpose. To investigate the effect of fumaric and lactic acids on the productivity of young cattle. Methods. In the process of the research general scientific methods were used: deduction, scientific hypothesis and abstraction. Methods of zootechnical analysis were applied to determine the chemical composition of feed. During animal experiments methods of analogue groups were used. Results. As a result of a scientific and economic experiment to study the effect of fumaric and lactic acids on meat productivity of young cattle, it was found that over the main period of the experiment the average daily gain was higher in young cattle of the second experimental group, which received by 63 g, or 8.5% more lactic acid, the difference is statistically significant (P <0.01). In young animals of the third experimental group receiving by 74 g, or 10.0% more fumaric acid, the difference is statistically significant (P <0.01), compared with the control group. In the final period of the experiment, the average daily live weight gain in young cattle of the second experimental group receiving lactic acid was by 5 g, or 0.60%, higher; in young animals of the third experimental group obtaining fumaric acid – by 8 g, or 0.90% higher, the difference is not statistically significant compared to the control group. The absence of the statistically significant difference in the average daily gain of young cattle between the control and experimental groups indicates the absence of aftereffects of lactic and fumaric acids on productivity in the final period of the experiment. Conclusions. Increase in the average daily gain of young cattle due to the use of fumaric and lactic acids is conditioned by the fact that they have shorter path of energy production compared to glucose, activate the pancreas, intestines and stomach enzymes formation.
