The effects of various types of feed supplements on in vitro rumen fermentability profile and digestibility
This study was conducted to investigate the effect of several feed supplements containing tea waste (tannin), sodium bicarbonate buffer, slow-release Non-Protein Nitrogen, calcium salts of fish oil, single cell protein (Spirulina sp.), Zn and Cu organic mineral, and seaweed (Glacilaria sp.) on in vi...

Summary: | This study was conducted to investigate the effect of several feed supplements containing tea waste (tannin), sodium bicarbonate buffer, slow-release Non-Protein Nitrogen, calcium salts of fish oil, single cell protein (Spirulina sp.), Zn and Cu organic mineral, and seaweed (Glacilaria sp.) on in vitro products of rumen fermentation, dry and organic matter digestibility. A completely randomized design was carried out for this treatment. In vitro incubation was performed in four runs, with each treatment being represented with two replications per run. The experimental diets were: T1 = Control (50% elephant grass + 30% tofu waste + 20% concentrate); T2 = T1 + 0.1% tea waste + 0.5% sodium bicarbonate buffer + 0.5% slow release NPN; T3 = T2 + 2% calcium salts of fish oil; T4 = T3 + 0.9% single cell protein (Spirulina sp.); T5 = T4 + Zn and Cu organic mineral 2%; T6 = T5 + 0.5% seaweed (Glacilaria sp.). The results showed that T6 treatment increased (p0,05) forward value of mean the increase of dry and organic matter digestibility. It was concluded that T6 treatment was the best effective combination that could improve rumen fermentability characteristics and digestibility). |
