Abstract

The current meta-analysis aimed to estimate the effect of different selenium (Se) sources on immune organs, plasma immunoglobulins, blood profiles, and broiler performances. Related studies that met standard presence criteria were identified and mined from the Scopus database. The database was developed from 38 articles. Data were analyzed using the OpenMEE, considering the difference between organic selenium as fixed effects and different studies as random effects. This study showed that organic selenium feed supplementation improved the feed conversion ratio and increased the average daily feed intake and gain of broilers. Furthermore, the mortality of broilers fed organic Se was significantly lower than that of those fed inorganic Se. For the immune organ of the broiler, organic selenium feed supplement enhanced the thymus and spleen organs but did not affect the bursa organ. IgA and IgM were significantly higher in the broilers fed organic selenium feed; meanwhile, IgG of broilers fed organic selenium was lower than those fed inorganic selenium. The total protein blood concentration of broilers fed organic selenium was significantly higher than those fed inorganic Se. Meanwhile, there was no statistically significant difference in the effects of selenium source on cholesterol. Triglyceride concentrations of broilers fed organic Se are significantly lower than those fed inorganic Se. The ratio of heterophile to lymphocyte in broilers fed organic Se is significantly lower than in those fed inorganic selenium. In conclusion, the organic selenium feed supplement can promote production performance and immune parameters of broilers.

Abstract

This study examined the effects of fat supplementation with high palmitic acid enriched with lecithin on the performance, egg quality, and fatty acid profile of quails. This study applied a completely randomized design to 330 female quails (Cortunix cortunix japonica) which were allocated into 5 different groups with 3 replicates of 22 birds. The groups were assigned as follows: T0 = commercial diet (control), T1 = commercial diet + 2.5% fat + 6% lecithin of added fat, T2 = commercial diet + 2.5% commercial fat, T3 = commercial diet + 5% fat + 6 % lecithin of added fat, T4 = commercial diet + 5% commercial fat. The results showed that the treatment group did not give effects on performances. However, the treatment group with fat level of 2.5% and 5% increased the score of egg yolk and eggshell thickness. Moreover, the treatment group decreased fat content in terms of saturated fatty acids and n-6/n-3 ratio of quail eggs. In conclusion, fat supplementation containing high palmitic acid enriched with lecithin proves effective in improving egg quality. However, the performance remains relatively similar across the groups.
