Abstract

The objective of this experiment was to evaluate chemical composition, in vitro fermentation and digestibility of dried and ensiled indigofera, papaya and moringa leaves. The leaves were subjected to artificial drying in an oven at 60oC for 24 h and ensiling treatment for 30 d under room temperature. Dried and ensiled samples were determined for chemical composition, silage fermentation characteristics and in vitro rumen fermentation and digestibility. The experimental design was a factorial design 3 × 2 in which the first factor was different leaves (indigofera, papaya and moringa) and the second factor was conservation treatments (drying and ensiling). Determination of chemical composition was performed in duplicate whereas in vitro evaluation was conducted in three replicates. Results showed that ensiling treatment decreased CP contents of indigofera and moringa but not papaya leaves. Ensiling also decreased NDF and NDICP contents of all experimental leaves in comparison to drying treatment. The pH of all silages was high and they were characterized with high ammonia concentrations. Ensiled indigofera tended to have lower IVDMD and IVOMD as compared to dried indigofera (P<0.1). It can be concluded that ensiling of high protein forages leads to considerable extent of proteolysis.

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.
