Abstract

Chicken feed perform a fundamental role in the poultry industry, as its proper formulation is essential for the healthy growth, development, and efficient production of poultry, as well as minimizing risks to animal and human health. Therefore, the composition of the feed must be precise, comprehensive, and essential to ensure that nutritional needs are met and to improve poultry performance. The objective of this study was to analyze the composition of chicken feed, evaluating the main nutritional components, such as moisture, protein, ether extract, fiber, and minerals, and verifying if they are compatible with the information presented in the nutritional table. To perform the analyses, samples of different feed brands were acquired, conditioned, and transported to the laboratory. Analyses of moisture (oven drying), ash (mineral matter), ether extract, protein, and crude fiber were performed. The moisture results were 9.1% and 8.5% for samples 1 and 2, respectively. For mineral matter, both samples showed results of 11%, while for the oil extraction analysis, results of 3.9% were obtained. In the protein analysis, results of 17.3% and 17.6% were obtained for samples 1 and 2, respectively. Similar results were also obtained for the crude fiber analysis, with 2.5% and 2.6% for samples 1 and 2. The results for the procedures were satisfactory, since when compared they meet the specifications stated on the packaging and, when compared with the literature, they present similar specifications, indicating that the levels used are within the expected range for broiler chickens in the fattening phase.
