Laying Performance

The objective of this study was to determine the effects of diet supplemented with marigold on egg yolk fatty acid composition and egg quality parameters. Sixty hens were assigned into three groups and fed diets supplemented with 0 (control), 10 g kg−1, or 20 g kg−1marigold for 42 days. Eggs collected at the 6th week of the study were analyzed for fatty acid analysis. Laying performance, egg quality parameters, and feed intake were also evaluated. Yolk color scores in the group fed the 20 g kg−1marigold-supplemented diet were found greater than control (10.77 versus 9.77). Inclusion of 20 g kg−1marigold in diet influenced egg weights adversely compared to the control. Diet supplemented with 10 g kg−1or 20 g kg−1marigold increased the levels of C16:0 and C18:0 and decreased levels of C16:1 (n-7) and C18:1 (n-9) in the egg yolk. Also, diet including marigold increased total saturated fatty acids (SFA) and decreased monounsaturated fatty acids (MUFA) in the egg yolk.

Mealworm Larvae

The purpose of this study was to investigate the effects of different levels of mealworm (Tenebrio Molitor) larvae meal in Japanese quail (Coturnix coturnix japonica) diets on performance, egg quality, yolk color, and yolk fatty acid composition. A total of forty-eight, 14 weeks-old laying quails were used with 4 replicates in control (basal diet), mealworm larvae meal (MLM) 2% or 4 % treatment groups. Results showed that independently of inclusion level dietary MLM did not affect performance and egg quality parameters. However, color values (L*, a*, b*) of egg yolk changed with the inclusion of both levels of MLM to diet (p<0.5). Outcomes also displayed dietary MLM altered the fatty acid composition of egg yolk dependably the additional level (p<0.5). Diets containing 2 and 4 % MLM did not affect total saturated fatty acid (ƩSFA) content, however, increased total monounsaturated fatty acids (ƩMUFA) (p<0.5). Both supplemental levels of dietary MLM decreased significantly the total polyunsaturated fatty acids (ƩPUFA) of the yolk compared to the control group (p<0.5). According to outcomes of this study, MLM may use in safe as feed material instead of soybean meal at levels of 2 or 4 % without effect on performance parameters in laying quail diets.
