Comparação do desempenho de frangos de corte alimentados com rações de diferentes marcas comerciais

Abstract

The internship was carried out with the aim of consolidating theoretical-practical knowledge about the raising of broiler chickens, where activities were monitored in two batches. Among the practices carried out include technical assistance activities, temperature control, temperature, housing, litter management, vaccination, supply of water and feed, as well as performance assessment through the productive efficiency index (IEP). The IEP was 263 for the first batch and 336 for the second batch. During the internship, it was developed a case study with the aim of comparing two brands of feed sold in the province of Maputo on the productive performance of broiler chickens, the study took around 45 days (including cleaning, disinfection and sanitary emptying). The tested rations were designated as treatment A (TA) and treatment B (TB). In the test, ed the effect of starter (0-21 days of age) and fattening (21-31 days of age) diets, having been administered ad-libitum. In each treatment, 99 chicks from the line were used. gem ross making a total of 198 birds. The animals were distributed in a design completely randomized design (DIC) and in the first stage (0-21 days) each treatment was constituted by a single group, while in the second stage (21-31 days) each treatment ment was repeated three times, that is, three experimental units per treatment (33 birds for each repetition). The performance of the birds was evaluated through feed consumption (CR), Live weight (PV), feed conversion (CA), average daily gain (ADG), viability (V), uniformity and production efficiency index (IEP). In the period from 0 to 21 days, the TA diet presented lower CR (1172.99g), PV (793.17g), and higher CA (1.6), in relation to TB where the CR was 1205.73g; the PV of 943.68g; and AC of 1.3. At 31 days the results for the CR, PV, uniformity, CA, Viability, and IEP were 2374.44 g; 1575.31g; 57.45%; 1.5; 94% and 321.6 for TA, and were 2436.69g; 1796.15g; 52.58%; 1.3; 97.98% and 406.5 for treatment B, respectively.
