Avaliação de desempenho e custos de produção de Frangos de corte alimentados com diferentes rações comerciais

Abstract

The pre-professional internship is one of the main tools for improving the knowledge acquired during training and integrating the trainee into professional life. The objective of this work was to evaluate the productive performance and production costs of chickens fed with different commercial feeds. The internship consisted of monitoring three batches of broilers, where activities such as technical assistance, housing, water and feed administration, performance evaluation, litter management, cleaning of the shed, vaccination, weighing and records were carried out. During the internship, a case study was developed, the objective of which was to evaluate the production costs of broilers fed with different commercial feeds. The study was carried out in two batches, where two commercial feeds were tested (A1 and A2). A total of 400 one-day-old chicks of the Ross 308 ® line were used, with 200 chicks housed in each batch. The experimental design was completely randomized, in which 2 treatments with 4 replicates composed of 25 birds each were set up. Performance was evaluated based on feed intake (CR), weight gain (GP), average daily gain (ADG), feed conversion (CA), viability (V), uniformity (U), and the productive efficiency index (IEP). In the analysis performed at 31 days of age, no significant differences (p> 0.05) were observed for CR, which was 2,405.49 g in T1 and 2,253.30 g in T2; and for CA, where values ​​of 1.42 and 1.55 were observed for T1 and T2, respectively. However, significant differences (p <0.05) were observed for GP and IEP, where GP was 1,687.55 g for T1 and 1,459.68 g for T2. Regarding the IEP, the productive performance was 383.32 for T1 and 304.25 for T2. Regarding costs, it is observed that T1 presented a higher total feed cost in relation to T2 with a variation of 5,145.00Mt. For the unit cost per bird produced and marketed, a higher cost was observed for T1 (254.3 Mt; 263.56), compared to T2 which was (228.6 Mt; 224.7 Mt), respectively. For the contribution margin, it was observed that treatment T2 had the highest contribution margin of 9,287.05 Mt, compared to T1 which was 3,601.25 Mt. For the composition of the costs in total, it was observed that variable costs had a higher percentage at 98.81% in relation to fixed costs at 1.19%; and of the composition of variable costs, feed and chick costs contributed 80.47% of this value.
