Abstract

This study was conducted to determine the relationship of birth weight of calves, sex ratio of the calves, and the age of the dam to the length of pregnancy in buffaloes resulting from artificial insemination in Kampar District. The method used in this research is the descriptive method by displaying the average and standard deviation. The total number of buffaloes that were artificially inseminated in 2018 and gave birth in 2019 was 21 buffalo-cows. Data were analyzed with the Pearson Product Moment (PPM) correlation. The parameters measured in this study were the length of pregnancy, calf birth weight, calf sex ratio, and dam’s age. The results showed a positive correlation between the birth weight of the calves, sex ratio of the calves, and the age of the dam to the length of pregnancy of 1.4%, with an average length of pregnancy, calf birth weight, and sex ratio of 351.81 days, 27.38 kg, and 1: 1 respectively.

Abstract

This research was conducted to determine physical quality, the nutritional quality and characteristics of antimicrobial compounds from fermented oil palm fronds (FOPF). This research was carried out using a Complete Randomized Design with 4 treatments and 4 replications. The following treatments were performed by the addition of different additives namely: 10% poultry manure, 10% cow feces, 5% urea and 5% molasses. All treatments were extracted in stages using n-hexane, ethyl acetate and methanol. The observed parameters were physical quality (pH, aroma, color, and texture), nutritional quality (neutral detergent fiber (NDF), acid detergent fiber (ADF), hemicellulose, cellulose and lignin), yield of extract, class of bioactive compounds and the antimicrobial activity test of extracted compounds. The data were analyzed using a one-way analysis of variance and differences between treatments were tested using Duncan's multiple range test. The addition of different additives has a very significant effect (P < 0.01) on the lignin content; significant effect (P < 0.05) on pH, aroma, color and texture; and no effect on the content of NDF, ADF, hemicellulose and cellulose. The highest yield of extract was obtained from methanol extract with the addition of poultry manure. The methanol extract on the addition of poultry manure and urea were identified as compounds in the steroid, tannin and phenolic classes. The highest antimicrobial activity test against Escherichia coli (12.83 mm) was obtained from FOPF extract (1%) with addition of poultry manure, while highest antimicrobial activity test against Staphylococcus aureus (11.67 mm) was obtained from FOPF extract (4%) with addition of molasses. The conclusion of this research was FOPF with addition of poultry manure provides good physical quality, nutritional quality and can inhibit the growth of E. coli and S. aureus at a concentration of 1%.
