Resumo: |
Two studies were conducted to evaluate the effect of using four types of flour of fish silage in the diet of broilers. A total of 540 male broiler chickens of Cobb 500 were used. The experimental design was completely randomized design with 5 treatments consisting of a reference diet and four test diets containing 40% of waste from filleting fish with different sources of carbohydrates, producing flour with bran fish silage mesquite (SFA), flour scanning cassava (SFVM), corn meal (SFM), and cassava peel (SCM). In the first study, 180 chicks with eight days of age were housed in metabolic cages and divided into six replicates of 6 birds each to assess the chemical composition, energy values of silages and the transit time of feed in the gastrointestinal tract of birds. The AME and AMEn of flour fish silage were respectively for the SFA 3804kcal/kg and 3563 kcal / kg for SFVM 3807 kcal / kg and 3567 kcal / kg for SFM 3842 kcal / kg and 3600kcal / kg, and for SCM 3806 kcal / kg and 3566 kcal / kg and did not differ significantly between them. The diet with the highest transit time was 195.0 min and SFM had the lowest time been 154.3 min SFA. In the second experiment, a 360 chicks housed in cages located in six replicates of 12 birds each and subjected to the same treatment from the previous experiment in period 1 to 33 days, however, the finishing ration was used the same reference All treatments in order to leave no undesirable taste in the flesh of the poultry. For weight gain of 1 to 33 days all treatments differed from the reference treatment, resulting in compensatory gain final stage to less SFVM. The feed conversion ratio of 1 to 33 days had the worst result and the SFA SFVM, 1-42 days coversão not differ among treatments. There was no significant difference in glucose level in the birds fed and fasted state between treatments. Sensory tests showed no differences in the flavor of the meat of birds between treatments test and standard treatment. Based on the composition obtained, these fish silage has the potential to be used in diets for broilers, but the silage SFVM proved inferior others, weight gain provided by this silage was the smallest and the only treatment that differed reference. Diets containing fish silage did not affect the flavor of the meat of broiler chickens. |
