Uso da torta de sementes de moringa (Moringa oleifera Lam) na alimentação de frangos de corte

Abstract

Moringa oleifera, native of India, is a leguminous plant that grows in the tropical and subtropical country. This plant is used in traditional medicine, the leaves are highly nutritious and used in human food and animal feed, the seeds are used as a clarifier of turbid water and contain large amounts of edible oil and the cake, by-product remaining after the oil extraction, can be used as a protein supplement or as additives in animal diets. The objective of this work was to evaluate the Moringa oleifera seed cake (MOSC) use in the broilers diet on growth performance, internal organ performance and blood parameters. A total of 288 days old chicks were distributed in a completely randomized design with eight birds per experimental unit, six experimental treatments were used with MOSC inclusion at the concentrations of 0; 0.5; 1.0; 1.5; 2.0 and 2.5% in the broilers diet (kg / kg). Data were submitted to analysis of variance and regression at 5% of probability. In the period from 1 to 10 days the MOSC inclusion in the broiler diets decreased significantly the feed intake (FI) and weight gain (WG) at 2.0 and 2.5% levels. In the period from 1 to 21 days, the FI was significantly decreased by the MOSC inclusion level of 1.5; 2.0 and 2.5%, the WG was affected significantly by the 2.5% of MOSC level and the feed conversion (FCR) decreased significantly by the inclusion of 2.0 and 2.5%. In the period from 1 to 35 days, the inclusion of 2.0 and 2.5% of MOSC reduced significantly the FI, and the7 FCR was reduced significantly by the levels of 1.5; 2.0 and 2.5%. In the period from 1 to 42 days, there was a significant decrease of FCR by the MOSC inclusion levels of 2.0 and 2.5%. The increasing inclusion of MOSC did not significantly affect any internal organs such as the liver, pancreas, spleen, bursa, gizzard, proventriculus and any blood parameters such as aspartate aminotransferase (AST), alanine aminotransferase (ALT), albumin, urate, total proteins and creatinine. It is recommended to use the MOSC in the broilers diet in the initial phase of 1 to 21 days at the maximum concentration of 1.5%, while from 21 days the inclusion of 2.5% of MOSC improved the feed conversion of birds. The inclusion of the MOSC did not affect the viscera and blood parameters of the birds at the concentrations studied.
