| Popis: | Fermentation has been practiced to bio convert inorganic substances into more readily available nutrients. Selenium is an important trace mineral functioning to improve growth and health status. A study was carried out to determine the carcass percentage and organ development of broilers fed fermented diets with the addition of selenium. Rice bran from the local market was purchased and finely ground. One kg rice bran added with 1 g sodium selenite as source of selenium (Se) was autoclaved for 20 minutes at 20 psi. The autoclaved rice bran was added with distilled water up to 80% moisture concentration. The autoclaved mixture was incubated with two different fungi (Aspergillus niger and Saccharomyces cerevisiae) for 120 hours to produce fermented rice bran with A. niger (FRBAN) and fermented rice bran with S. cerevisiae (FRBSC). The study used 140 day-old-chicks as experimental animals. The birds were kept in cages for 6 weeks and fed 5 different diets ad-libitum. The treatments were control basal diet (T-1), control + 0.4 ppm Se (sodium selenite; T-2), control basal diet + 0.4 ppm Se from Selplex commercial feed additive rich in Se (T-3), control diet + 0.4 ppm Se derived from FRBSC (T-4) and control basal diet + 0.4 Se derived from FRBAN (T-5). A completely randomized design was adopted in this study with 5 treatments and 4 replications. Results of the study indicate that percentages of liver, gizzard, and carcass were lower in birds fed diets containing sodium selenite. Shorter relative length and diameter of the small intestine were also found in the birds offered the sodium selenite – supplemented diet. The percentages of abdominal fat and breast muscle were not affected by treatment diets. In conclusion, the addition of Se in the form of sodium selenite negatively affected percentages of the liver, gizzard, carcass and digestive tract dimensions. Fermentation of rice bran containing sodium selenite could minimize the detrimental effect of inorganic selenium. |
