Abstract

The administration of anabolics for the performance of bovine animals was 1 ml per 90 kg of body weight every 30 days. The block design evaluated the number of animals by administering Anabolic ST (A) and Boldemax (B). For the first block, group A was the animals with an approximate weight of 354 (+-41) kg, group A was 18 heads and group B was 24 heads, and each animal was weighed for 41 days. For block two, animals weighing approximately 479.5 (+- 26.9) kg. Group A consisted of 23 head and group B consisted of 23 head and each animal was weighed for 39 days. For block three with animals weighing approximately 524 (+-6.4) kg. Where group A will have 27 head and group B 13 head and each animal will be weighed for 55 days. The statistical analyses of the results were analyzed using the student's t test for the following parameters: feed intake, mean total weight gain, feed conversion. The ANOVA test was performed to determine the statistical significance between means, and a Tukey test (P < 0.05). There was a statistical difference between treatments (P < 0.05) of the three experimental blocks with the anabolic Bodlemax in the total mean gain in kg (160, 237, 68.6 versus 137, 187, 61.4); Feed conversion kg. (3.92, 6.34, 1.76, 1.8 versus 3.96, 6.2, 1.72), of the blocks that consumed this anabolic. It is concluded that there is a significant difference between GMTP of animals with a confidence level of 95%. that the anabolic Boldemax was applied compared to the Anabolic ST and there is a better feed efficiency due to the cost when administering Boldemax in the treatments evaluated.
