Proximate analysis of pelleted sorghum-based feeds as substitute for corn

The study aimed to evaluate the proximate analysis of pelleted sorghum-based feeds as a substitute for corn and it was conducted at Cagayan State University-Piat Campus. The specific objectives were to formulate a sorghum-based feed ration and evaluate the proximate analysis of the formulated pelleted feeds. In this research, a Completely Randomized Design with three (3) replications was adopted. Results revealed that the uppermost crude protein and fiber content was found in Treatment 3 (50% corn + 50% sorghum), while Treatment 2 (75% corn + 25% sorghum) displayed the highest percentage of crude fat. While Treatment 4 (25% corn + 75% sorghum) also established high levels of calcium and phosphorus content. Analysis of variance reveals no significant differences in crude protein, crude fiber, and phosphorus content among the five treatments tested, except for crude fat and calcium, which exhibited highly significant differences. It was observed that the variation in the fat content in treatments T2 and T3 may influence the efficiency of calcium absorption. Since sorghum has a higher fat content and is possibly more effective in promoting calcium absorption, its presence at higher proportions leads to improved levels of both crude fat and calcium. It is recommended that integrating sorghum into the animal diet can increase nutritional aspects, particularly fiber and calcium, which is beneficial depending on the dietary requirements of the target animals.
