Abstract

Correction to: Tropical Animal Science Journal, 47(3), 371-380. https://doi.org/10.5398/tasj.2024.47.3.371 An error occurred on Page 373, Table 1, on “Note” under the table. The previous version was written: 1Total digestible nutrients (TDN) were calculated using TDN (%DM). TDN = -17.2649 + 1.2120(PK) + 0.8352(BETN) + 2.4637(LK) + 0.4475(SK), according to Wardeh (1981). The correct version should be: 1Total digestible nutrients (TDN) were calculated using TDN (%DM). TDN = -17.2649 + 1.2120(CP) + 0.8352(NFE) + 2.4637(EE) + 0.4475(CF), according to Wardeh (1981).

Abstract

This study aimed to evaluate the effects of energy and organic zinc supplements, specifically zinc palm oil soap (ZPOS), on digestibility and unsaturated fatty acid profiles in vitro. The study used a completely randomized design with 4 treatments and 5 replications. The treatments were: T0= basal diet without supplementation, T1= basal diet + 5% palm oil (PO), T2= basal diet + 5% partial ZPOS (3.75% ZPOS + 1.25% PO), and T3= basal diet + 5% ZPOS. The inoculum source was rumen liquid from three fistulated female dairy goats and was homogenized. The goats were fed ration consisting of corn straw, soybean hulls, and concentrate containing total digestible nutrients (TDN) 63%, crude protein (CP) 14%, and neutral detergent fiber (NDF) 35%. Results showed that both 5% partial ZPOS and 5% ZPOS supplementation (T2 and T3) resulted in the increase of total volatile fatty acids (VFA), acetate, propionate, butyrate, unsaturated fatty acids (USFA) and a decrease in the ratio of acetate/propionate (A/P) compared to the control and supplementation of 5% PO (p<0.05). Supplementation of 5% partial ZPOS (T2) is better than 5% ZPOS because increased the digestibility of ether extract (EE), crude fiber (CF), NDF, and acids detergent fiber (ADF) (p<0.05) and decreased of methane compared to the control (p<0.05). In conclusion, adding 5% partial ZPOS (3.5% ZPOS and 1.5% PO) increases fiber digestibility, VFA, LCFA, and USFA concentration, and decreases methane production in the rumen liquid.

Abstract

This study examines how Islamic work ethics and quality of work life affect employee performance, using Sultan Agung Islamic Hospital in Semarang as a mediating variable. One hundred workers completed questionnaires for the quantitative study, which was then evaluated using the Sobel Test and multiple linear regression. The findings show that Islamic work ethics and quality of work life have a positive impact on employee engagement and performance, while employee engagement has a positive impact on performance but has not been able to mediate the relationship between the two variables and performance. It follows that balancing technical, spiritual, and work-life factors is necessary to improve performance. It is anticipated that Sultan Agung Islamic Hospital would keep enhancing the standard of living and Islamic principles. For more general findings, more study with more variables and a wider variety of participants is advised.
