%X Objetivou-se avaliar a influ那ncia da adi  o de diferentes 車leos vegetais em ra  es para poedeiras comerciais sobre o desempenho e a qualidade interna e externa dos ovos. Foram utilizadas 224 poedeiras da linhagem Hy Line W-36, distribu赤das em um delineamento de blocos ao acaso, com sete tratamentos de quatro repeti  es. Os tratamentos consistiram em sete ra  es com 2850 kcal EM/kg e 18% de prote赤na bruta: T1- controle; T2 - 2% 車leo de soja; T3- 4% 車leo de soja; T4- 2% 車leo de linha a; T5- 4% 車leo de linha a; T6- 2% 車leo de algod o; T7- 4% 車leo de algod o. As vari芍veis estudadas foram: produ  o de ovos (ave/dia), consumo de ra  o (g/ave/dia), peso dos ovos (g), convers o alimentar (kg/kg), percentagem de gema, clara e casca, colora  o da gema e teor de colesterol dos ovos (mg/g). A adi  o do 車leo vegetal n o alterou as caracter赤sticas de desempenho, a qualidade e o teor de colesterol nos ovos, em rela  o 角 dieta sem 車leo. A adi  o de 4% de 車leo vegetal melhorou a colora  o da gema, entretanto, a linha a ocasionou uma redu  o na percentagem da gema. A suplementa  o de 車leo vegetal nas dietas de poedeiras n o alterou o teor de colesterol dos ovos. It was evaluated the influence of the addition of different vegetal oils in diets for commercial laying hens on performance and internal and external egg quality. We used 224 laying hens Hy Line W-36, distributed in a randomized block design with seven treatments and four replications. The treatments consisted of seven diets with 2850 kcal ME/kg and 18% crude protein: T1 - control diet; T2 - 2% soybean oil; T3 - 4% soybean oil; T4 - 2% linseed oil; T5 - 4% linseed oil; T6 - 2% cottonseed oil; T7 - 4% cottonseed oil. The variables studied were: eggs production (hen/day), feed intake (g/hen/day), egg weight (g), feed:egg mass ratio (kg/kg), shell and albumen, yolk percentages, yolk coloration and cholesterol eggs (mg/g). The addition of vegetal oil did not alter the performance characteristics, quality and content of cholesterol in eggs, in relation to the control diet. The addition of 4% vegetal oil improved the yolk coloration, however, the linseed caused a reduction in yolk percentage. The supply of vegetal oil in the diets of the laying hens did not alter eggs cholesterol.
