| ABSTRACT Water lentils (Duckweed [DW])(Lemna gibba), in irrigation ponds, was evaluated by replacing two levels of soybean meal (SBM) on performance and egg quality of laying hens of 54 weeks of age. A total of 72 white Lohmann laying hens were randomly allocated into 3 treatments with 6 replicates/treatment, 4 hens/replicate in a randomized complete block design. Treatments were: control group (DW0%) with (SBM) as the main source of protein, T1 (DW10%) and T2 (DW20%), where duckweed replaced 10% and 20% of SBM for 9 weeks. No significant differences were observed among the dietary treatments in body weight change, feed conversion ratio, egg weight and mortality rate. Replacement with (DW20%) decreased (p<0.05) feed intake, egg laying rate and egg mass.... |

| ABSTRACT The present study examined the effect of supplementing the diets of laying hens with Pistacia terebinthus seed meal on egg quality during different storage intervals. A total of 192 laying hens (Babcock) were divided into six groups, and each group was further divided into four subgroups with eight hens each. Pistacia terebinthus seed meal was added to the diets of laying hens in the experimental groups at a rate of 0, 10, 20, 30, 40, and 50 g kg−1 of feed. At the end of the study (56 days), a total of 288 eggs (48 eggs from each group) were collected randomly. Seventy-two eggs were analyzed on day zero of storage, while the other eggs were stored at a temperature of 4 °C. The remaining eggs were analyzed after 10, 20, and 30 days of storage. The... |

| Consumer demands for healthy foods have stimulated the research on the use of natural products in animal nutrition. Annatto can be used a pigmentation source to improve yolk color of commercial eggs. This study aimed at evaluating the effects of the inclusion of ground annatto seeds on the performance and egg quality of layers fed sorghum-based diets. A total of 336 40-w-old hens were distributed according to randomized blocks into seven treatments with six replicates of eight birds each. The following treatments were applied: T1- egg production feed based on corn and soybean meal; T2- egg production feed based on sorghum and soybean meal; T3, T4, T5, T6, and T7- egg production feed based on sorghum supplemented with 0.5, 1.0, 1.5, 2.0, and 2.5% ground... |
