SALVADOR TASAYCO, Elías  e  BONIFACIO HUALLANCA, Sandra Jackeline. Diet energy management in reducing feed cost in egg production. Rev. Inv. Cs. Agro. y Vet. [online]. 2021, vol.5, n.15, pp.126-132. ISSN 2664-0902.  https://doi.org/10.33996/revistaalfa.v5i15.133.

High prices of corn and soybeans increase the cost of the diet by more than 30%. Metabolizable energy (ME) is the key component of that cost. Reassessing the level of ME allows to define the optimal consumption of food and energy to improve the cost of feeding. The objective was to determine the effect of three levels of ME on the productive response, egg quality and margin on feeding cost of laying hens. 192 hens of the 80-week-old DEKALB line were used, under a complete Random Design. ME levels: 2650, 2750 and 2850 Kcal / Kg, with four repetitions. The productive response, egg quality and margin on feed cost were evaluated. For statistical analyzes, the GLM procedure of SAS v 9.4 was used. Egg quality was not affected. Food consumption increased significantly (P <0.05) as the level of ME in the diet decreased. Live weight gain was greater with the lowest level of ME. The margin on the cost of feeding for egg dough was higher with the level of 2650 Kcal of ME / Kg with an economic retribution + 6.99%.
