Utilização do farelo de algaroba na alimentação de suínos na fase de crescimento.

Abstract

Swine farmers have been constantly concerned with finding food alternatives that will reduce their production costs. Less dependence on the two main inputs for pig feed, “soybean meal and corn” for the use of alternative feeds, may give greater stability to this sector. The mesquite, due to its adaptation to the semi-arid conditions of the Northeast and for its multiple uses, is included as an agronomic alternative. Therefore, the main objective of this study is to evaluate the effects of the inclusion of mesquite bran in the pig diet in the growing phase. Four crossbred pigs, from the city of Boa Vista-PB, were used, allocated in a stall (2, 5x3.0), in an intensive system, with ration and water at will. They were submitted to a corn-based diet (34.5%), mesquite meal (34.5%), soybean meal (27%), and a growth nucleus (4%). Daily feed intake (CDR), daily weight gain (GPD) and weekly weight gain (GPS) of the animals were observed. Daily feed consumption (CDR), daily weight gain (GPD) and weekly weight gain (GPS) of animals, food conversion and economic viability were observed. , 2 kg, and on the days of greatest consumption it was on average 4 kg per animal. The animals gained an average of 0.93 kg per day. And in the last week of the experiment, he gained 8.6 kg, that is, 1.22 kg a day. The feed conversion was 2.4 kg. Regarding the feasibility of including mesquite bran in the pigs' feed, it proved to be viable, the cost per kilogram was around R $ 13.40.
