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 selenium (sodium selenite) added to palm kernel cake (PKC) before fermentation on production, selenium content, and quality of eggs. The PKC was added with 0.1% sodium selenite and 1% baking yeast (Fermipan®). The mixture was added with ster-ile distilled water to increase the water content of the substrate. The substrates were fermented at room temperature for 5 days. The fermented products of selenium-rich fermented palm kernel cake (SRFPKC) were dried and fed to the laying hens. The experimental diets used were T-0: without SRF-PKC, T-1: 0.25% SRFPKC, T-2: 0.50% SRFPKC, T-3: 0.75% SRFPKC and T-4: 1.0 % SRFPKC. The diets were given to 180 laying hens aged 22 weeks for 14 weeks. Data on egg production, feed intake and feed conversion ratio were recorded. Feed digestibilities of dry matter and protein were measured based on the method of total fecal collection. Egg qualities and egg weight loss were done using eggs stored for 1 and 30 days. Selenium and cholesterol contents of eggs were also measured. This study used a completely randomized design and was analyzed by analysis of variance. The results showed that the addition of SRFPKC increased egg production, hen day, egg weight, egg selenium, feed digest-ibility, improve FCR (P<0.05) and inhibit the process of decreasing the quality and weight of eggs stored for 30 days (P<0.05). In conclusion, the addition of SRFPKC increased egg production, feed digestibility, and egg selenium, improve FCR and slow down the deterioration of egg quality stored for 30 days.
