اثر جایگزینی سطوح مختلف جلبک سارگاسوم ایلیسیفولیوم به جای سیلو بر عملکرد و فرآسنجههای خونی وشکمبه ای بره های زل

Abstract

The seaweeds like Sargassum ilicifolum arecan used for animal nutrition. The aim of this study was evaluated the nutritional value of Sargassum ilicifolum as a food supplement in the diet of sheep. In this experiment were five diets containing zero, 10, 20, 30 and 40 percent of the seaweed were used. A completely randomized design was used to this purpose. In this study, the chemical composition of seaweed(Sargassum ilicifolum), DMdegradability,concentration electrolytes parameter from blood,rumen and performance parameters were measured. Treatment effects on feed intake were not significant(p>0.05). Water consumption increased with increase in algae value in deit. In this investigation in situ degradability of dry matter of seaweed in the intervals 0, 4, 8, 16, 24, 48, 72 and 96 hours was studied, amount of part fast degradability (a) and part slow degradability (b) for Sargassum illicifolumwere respectively 42% and33.6%. The effective degradability in outflow rates 2%, 5% and 8% were 49.6%, 45.5% and 44.3%, respectively. Effective treatment wasnot significant on the concentration Na and Cl, but was significant on the concentration K (P<0.05).The effects of different levels of algae Sargassum illicifolium on the potassium, cholesterol and triglycerides concentration were significant (p<0.05). Based on the results,Sargassum illicifolium can be fed to 30 percent of ruminants diet in substitution of forages
