ABSTRACT The objective of the present study was to evaluate production and egg quality as well as the intestinal morphometry of laying hens fed diets supplemented with marine microalga Dunaliella salina. Six hundred laying hens were allocated based on a completely randomized design into five treatments (0, 0.25, 0.50, 0.75, and 1% inclusion of D. salina biomass) with 12 replicates of 10 hens per treatment. The experiment was divided into three periods of four weeks each, totaling 84 days. During […]

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 […]

The objective was to evaluate the effects of natural pigments from marigold extract and paprika to Japanese quails fed sorghum-based diets. One hundred and eight Japanese quails (Coturnix japonica), with 98 days of age were distributed in a complete randomized design in a split plot arrangement, with five treatments and six replicates of six birds each. The experiment was divided into six periods of four days each, totaling 24 days. Parameters productive performance and quail egg quality were evaluated. Yolk […]
