The response of laying hens fed fermented pineapple peel waste by indigenous microorganism from bamboo sprout

Resposta de galinhas poedeiras alimentadas com resíduos fermentados de casca de abacaxi por microorganismos indígenas do broto de bambu

ABSTRACT

The bromelain enzyme content in pineapple peel waste predicted to promote digestive tract health and a positive effect on egg quality. This research aimed to evaluate the use of fermented pineapple peel waste in laying hens diet on egg quality. A total of laying hens 200 birds with Isa Brown strain, egg production of 70%, The average egg weight and body weight were 58.58 g/egg, and 1.62 g/bird, respectively. A completely randomized design was used, 5 different levels of fermented pineapple peel waste as treatment (0, 5, 10, 15, and 20%), and all treatments were repeated 4 times. Egg shell thickness, egg shell strength, haugh unit, egg yolk fat, and egg yolk color were measured. The use of fermented pineapple peel waste in the diet of laying hens up to 20% highly significant (P<0.01) on egg yolk color, and did not negative effect (P>0.05) on egg shell thickness, egg shell strength, haugh unit, and egg yolk fat. Fermented pineapple peel waste can be used as much as 20% in laying hens diet without disturbing egg quality and improve egg yolk color.

Key words:
egg quality; indigenous microorganism; laying hens; pineapple peel waste; egg yolk color
