Abstract:The study investigated the effects of low protein diet and amino acid supplementation on production performance of laying hens from 49–57 weeks. A total of 135 chickens were divided into 3 groups: 17%CP, 15%CP and 15%CP supplemented with
amino acid (AA). The results showed that the 15% CP group consumed less feed (P less than 0.01). Adding AA to 15%CP improved feed intake, Met intake, BWG, egg mass (P less than 0.01) and egg production (P less than 0.05), while FCR and egg quality
were … Show more
