Productive Yield And Economic Feasibility Of Forage Hays In Feed For Naked Neck Chickens

Abstract

In order to evaluate the productive response and economic viability of diets that included hays as alternative forage for birds in a semi-intensive system, a performance test was held, in which 600 Label Rouge birds were distributed in a completely randomized design with five treatments, six replications, and twenty birds per plot. The control diet (RCO) was based on corn grain and soybean meal and used as a reference for the inclusion of forage hay, 20% by hays Silk Flower (Calotropis procera), Maniva Cassava (Manihot esculenta) , Mata Pasto (Senna obtusifolia) , or Leucaena (Leucaena leucocephala). The average for RCO feed intake, RMM, RFS, RMP, and RLE were 0.1050, 0.1470, 0.0888, 0.1411, and 0.1441 kg/bird/day, respectively, and feed prices were 1,489, 1,209, 1,189, 1,179, and 1,249 (R$/kg), respectively. Therefore, the total costs of food in the 84-day period of semi-confinement of the birds per ration were 1950,67, 1790,70, 1061,90, 1676,04, and 1813,60 (actual R$), respectively. These results showed a relative decline in power with regard to cost via including hay as an alternative forage in diets, but after evaluating the performance in weight gain and carcass yield of birds, the total revenue was lower in each of the feeds with hay forage and thus the economic efficiency and average cost rates were better with the RCO feed; however, the RMM had superior profitability compared to other diets with hay.
