| ABSTRACT This investigation was carried out to determine the effect of Essential Fatty Acids proportion (EFAs [n-6, n-3]) in feed through the mixture of soy, olive, canola or chia oil on EFA profile in eggs as well as productive and reproductive performance of Japanese quail. We used 120 quail from 7 to 22 weeks of age, in 15 cages in groups of 6 females and 2 males assigned according to the completely randomized design to 3 treatments with 5 replicates. The treatments were n-6:n-3 proportions 10:1 (control), 4:1 and 1:1. FA profile in yolk, feed intake, laying rate, egg weight, fertility, hatchability, and embryonic mortality were measured. In the egg yolk, n-6 content was similar in the proportions (p>0.05), while n-3 content increased (p<0.01) as... |

| ABSTRACT This study was performed to determine the effect of shell colour in eggs acquired from Ross-308 broiler breeders on the interior and exterior quality of the egg, the antibody content of the egg yolk, and growth performance. The shell colours of a total of 1350 eggs were classified, using a colorimeter, into three groups: dark (E<64), medium (E:64.00-67.00), and light (E>67). The difference between groups with respect to egg weight, shape index, shell weight, and Haugh unit value was significant. Egg yolk antibody content (IgY) was 6.658 mg/mL in the dark colour group, 5.130 mg/mL in the medium colour group, and 5.242 mg/mL in the light colour group. Among incubation characteristics, the fertility rate as, in order, 94.66%, 92.14%, and 87.92%... |
