Abstract

This study was conducted to determine the effects of the fermentation duration of coconut dregs (CD) by Saccharomyces cerevisiae and the addition of ammonium sulfate on the growth performance, feed digestibility, carcass, and digestive organ developments. A finely ground CD was autoclaved at 20 psi for 20 minutes and added distilled water to meet 80% moisture content. The autoclaved substrate was added with different concentrations of ammonium sulfate and fermented with Saccharomyces cerevisiae to produce Saccharomyces cerevisiae-fermented CD. A total of 192 day-old-unsexed Cobb broiler chicks were used and kept for 6 weeks. The birds were fed experimental diets ad-libitum. The experimental diets were produced by two durations of fermentation (5 days and 7 days) and three levels of ammonium sulfate (0%, 0.2%, and 0.4%) in 4 replicates. The experimental diets were offered ad-libitum and water were available at all times. Fermentation decreased lipid and crude fiber content of CD and the addition of ammonium sulfate increased protein content and amino acid concentration of CD. The bodyweight gain of birds increased when the CD was fermented for 5 days and with the addition of 0.2% ammonium sulfate. Dry matter digestibility and protein digestibility were improved when CD was added with 0.2% ammonium sulfate. In conclusion, fermenting CD for 5 days increased body weight gain and the addition of 0.2% ammonium sulfate improved the feeding value of the diet and growth of birds.

Abstract

A study was conducted to determine the effect of enzymatic pre-digestion of fermented palm kernel cake in the laying hen’s diet on the performance production, nutrient digestibility, egg quality, and egg chemical content. Palm kernel cake (PKC) was added with 3% ammonium sulfate and then fermented by using Saccharomyces cerevisiae for 5 days (FPKC). The FPKC was hydrolyzed with mannanase to produce enzymatic pre-digestion of FPKC (EPFPKC). The study used a completely randomized design with 5 treatments and 6 replications. The EPFPKC-containing diets were fed to 240 Lohmann Brown laying hens aged 19 weeks old for 3 months. The diets were D-1 (without EPFPKC), D-2 (5% EPFPKC), D-3 (10% EPFPKC), D-4 (15% EPFPKC), and D-5 (20% EPFPKC). Feed and drinking water were available at all times. Total fecal discharges were collected for three consecutive days to measure feed digestibility. The variables measured were feed digestibility, production performance, egg quality, lauric acid, cholesterol, and beta-carotene content of eggs. Data were analyzed with the variance analysis. The results showed that fermentation could increase the protein content of PKC and decrease the crude fiber content. The addition of EPFPKC in the diets increased dry matter, protein, and crude fiber digestibility and improved the quality of albumen and yolk during 28 days of storage at room temperature. Adding EPFPKC also increased the concentration of lauric acid and beta-carotene in eggs. In conclusion, the addition of 15% of enzymatic pre-digestion of fermented palm kernel cake (D-4) in the diet improves the quality of eggs stored for 28 days, and increases the concentration of lauric acid and beta carotene in eggs.
