Add Tag | Summary: | The Balanced Food industry has constantly increased its production with the highest growth in the world. Therefore, one of the industry's main problems is the shortage of raw materials such as corn; therefore, it is currently seeking to implement new raw materials for use in the different formulations of animal species. The present work aimed to elaborate on a balance using an optimal formulation to analyze the productive behavior concerning weight gain compared to a commercial balanced. The behavior of the weight gains of 40 red tilapias in the fattening stage fed with different proportions of Chinese potato meal (10, 20, and 30%) was evaluated. The red tilapias were reared for 30 days in a rustic pond with dimensions 2.5 (Length)* 2.5 (Width)*0.8 (depth) meters, which was divided into quadrants to carry out the study of the four treatments. (T0, T1, T2, T3). In addition, an analysis of variance and a Tukey test was used to determine the best treatment, showing that T1 with a 10% substitution of Chinese potato flour had a greater weight increase with a mean of 143.1975 grams compared to T2 (20% Chinese potato flour formulation) and T3 (30% Chinese potato flour formulation). In the same way, through the statistical analysis, it is deduced that there is no statistical difference (P=0.110) within the weight variable, and it is positioned as the best treatment throughout the study. On the other hand, the economic analysis shows that the benefit-cost is $1.46 for all the treatments, differing from one another by decimals, reflecting that, for each monetary unit invested, 0.46 cents of benefit is obtained, and, finally, it manages to be a competitive product option concerning the industrial balanced that is traditionally marketed. |
