Investigation of the effect of using Vinasse in the feed of Holstein male calves on the quality of their meat as a meal in the armies food ration

One way to increase the protein content of the soldiers' diet is to increase the protein content of red meat. The aim of this study was to investigate the use of vinasse in the feed of Holstein male calf and its effect on carcass meat quality.

Twenty-eight Holstein male calves were divided into four groups and were fed on the one of the experimental diets that were similar in energy and protein content over a period of 110 days. The diets differed in composition (Vinas + molasses) and silage with different ratios of Vinas instead of cottonseed meal, with four diets including no Vinase (control), 5%, 10% and 15% Vinas, respectively. At the end, the amount of ammonia nitrogen in the rumen fluid was measured as well as sampling from the locations of 10th, 11th, and 12th ribs to determine the chemical composition.

Between Vinas15% group and other groups, there was a significant difference in rumen ammonia nitrogen level at the end of the experimental period (p<0.05). Calves fed the control diet and the diet containing 10% of Vienna had the highest and the lowest fat thickness on the 12th rib, respectively. Mean protein to fat ratio increased with increasing Vinase level (p<0.05). Also, the mean moisture content and crude protein content of rib bones increased significantly with increasing Vinase level in the diet.

The results of the study showed that adding the vinase in the Holstein calf feed can increase the protein content to 16%, while reducing the fat content to 5%. Accordingly, it is possible to increase the protein content of the military’s ration by adding Viennas to the rations.
