Effect of processed lemon pulp with Saccharomyces cerevisiae yeast on protein and energy metabolism in Raini goats
Journal Title: International journal of Advanced Biological and Biomedical Research - Year 2014, Vol 2, Issue 6
Abstract
The aim of present study is investigating effect of treated lemon pulp by Saccharomyces cerevisiae yeast on protein and energy metabolism in goats was fed with this product. In this experiment 8 goats from raini breed were used for 21 days period; 16 days for adaptation and 5 days for sampling, to investigate the effect of processing lemon pulp by Saccharomyces cerevisiae yeast on protein receivement, retention and excretion and also energy metabolism. Goats were put in metabolic cages equipped to separate urine and feces collection system and they were fed with a diet containing lemon pulp and alfalfa with 40:60 proportion in maintenance limit. Collected data were analyzed statistically as a completely randomized design. After processing lemon pulp crude protein was increased whereas crude fat and nitrogen free extract were decreased significantly (P< 0.05). Digestibility of treated lemon pulp¥s crude protein was higher but digestibility of treated lemon pulp¥s crude fat was lower (P< 0.05). Consumptive nitrogen, feces nitrogen and urinary nitrogen were increased significantly whereas nitrogen retention did not change significantly also creatinin and total urinary protein were increased significantly. But uremic nitrogen and total blood protein did not change. Entirely processing lemon pulp with Saccharomyces cerevisiae yeast moreover increasing crude protein percent cause to increase digestive coefficient of lemon pulp¥s protein.
