The purpose of this study was to determine the effect of soursop leaf (Annona muricata), saffron white (Curcuma mangga Val.) and cherry leaves (Muntingia calabura L.) and theirs combinations in drinking water on performances and blood cholesterol of laying roosters that infected by Escherichia coli. This study was designed using completely randomized design (CRD) with 11 treatments and 3 replications and each treatment using the 4 roosters. That obtained 33 experimental units. The treatments were the drinking water contain decoction of soursop leaves (DS), saffron white (KP) and cherry leaves (DK), and combinations were as follows: R0: without decoction of herbs (control), R1: 6% of DS decoction, R2: 6% of KP decoction, R3: 6 % of DK decoction, R4: 2% of DS decoction + 4% of KP decoction, R5: 2% of DS decoction + 4% of DK decoction, R6: 2% of KP decoction + 4% of DS decoction, R7: 2% of KP decoction + 4% of DK decoction, R8: 2% of DK decoction + 4% of DS decoction, R9: 2% of DK decoction + 4% of KP decoction, R10: 2% of DS decoction + 2% of KP decoction + 2% of DK decoction. Parameters of performance were: feed consumption, water intake, body weight gain, feed conversion. The result showed that the treatment had no effect on the performances (feed consumption, water consumption, body weight gain, feed conversion).
Corrosion inhibition properties of eugenol derivatives have been elucidated by means of density functional theory at B3LYP/ 6-31G(d) level of theory. The quantum chemical parameters including the highest occupied molecular orbital (E HOMO) and lowest unoccupied molecular orbital (E LUMO), gap energy (∆E gab), ionization potential (I), electron affinity (A), the absolute electronegativity (χ), hardness (η), softness (σ), and the fraction of electron transferred (ΔN) are studied for investigating the corrosion inhibition performance of acetyleugenol derivatives. Effect of electron donating and withdrawing groups has been studied on the corrosion inhibition performance of acetyleugenol derivatives. The NH 2 (electron donating substituent) exhibits the highest inhibition efficiency, whereas the NO 2 (electron withdrawing substituent) exhibits the lowest inhibition efficiency. This study would have a significant contribution in designing highly potential eugenol based corrosion inhibitors.
The aim of this research was to know the effect of supplemented fermented purslane flour (FPF) in diet on the chemical quality, and microbiology of broiler chicken meat. One hundred DOC were used in this research. This research used a completely randomized design with 5 treatments and 4 replications. The treatments were K0 = commercial diet without FPF, K1 = commercial diet + 2.5% FPF, K2 = commercial diet + 5% FPF, K3 = commercial diet + 7.5% FPF, and K4 = commercial diet + 10% FPF. The variables studied were water content, protein content, and cholesterol levels of meat and contamination of Salmonella sp. Data were analyzed using Analysis of Variance (ANOVA). The results showed that the supplemented fermented purslane flour in diet significantly affected the water content and protein content of meat, but it did not significantly affect the cholesterol meat levels and contamination of Salmonella sp. It was concluded that the supplemented of fermented purslane flour in broiler chickens with a level of 10% was the best level. At this level, chicken meat is produced with the lowest water content while the highest protein content.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
