Addition of aminochelated zinc in the diet of broilers of the ROSS® line, at the Santa María farm, Department of La Libertad, El Salvador

Abstract

It is important to generate strategies to improve productivity and availability of animal protein to meet human demand. Aminochelated minerals are essential for broiler performance and are involved in several physiological processes. They participate in metabolic pathways in the animal body and play vital roles in functions including reproduction, growth, immune system and energy metabolism. The objective of this research is to evaluate the effect of adding 3 levels of aminochelated zinc to the ROSS® broiler diet on performance, efficiency and profitability. The research project was carried out at the Santa Maria farm, in the Santa Maria del Banco hamlet, Canton el Escalon, Municipality of San José Villa Nueva, Department of La Libertad. Between the months of November 2020 and April 2021, 192 1-day-old ROSS® line broilers were raised and fed four diets based on corn and soybean with and without the addition of zinc aminochelated zinc in different doses. The statistical model used was a completely randomized design, with four different treatments and four replicates, consisting of 12 experimental units in each. The addition of aminochelated zinc in the feed of broilers of the ROSS® line at a dose of 20 g per 45.45 kg (qq) of concentrate (T3), improved weekly weight gain by an average of 330 g, a mortality percentage of 0% and the lowest average feed consumption with 3.330 g (p<0.05). The addition of amino chelated zinc improved broiler performance and can be used in the feed during growth
