Slow-Release Urea as a Sustainable Alternative to Soybean Meal in Ruminant Nutrition
نویسندگان
چکیده
Three experiments were conducted to evaluate the feasibility of using a commercial slow-release urea product (SRU; Optigen®, Alltech Inc., Nicholasville, KY, USA) as partial replacement for vegetable protein sources in cattle diets. The first experiment was an vitro rumen fermentation that evaluated effect replacing soybean meal (SBM) nitrogen with from either SRU or free diets varying forage:concentrate ratios. second examined SBM on situ dry matter and degradability rumen. In third experiment, feeding trial (0% as-fed SRU) 1% 3% feed carbon footprint (CFP; total greenhouse gas emissions associated life cycle raw materials) toxicity potential growing beef cattle. Results showed up 1.3% did not negatively affect parameters. Supplementing favourably decreased ruminal accumulation ammonia lactic acid when compared urea. There no significant effective one-third replaced by study. Compared 0% diet, CFP 18% 54% diets, respectively. Additionally, diet health intake, blood hematological biochemical indices within physiological range healthy bulls, suggesting indication toxicity. Overall, these results indicate can be used sustainable alternative partially replace ruminant without compromising function ruminants.

Since the use of antibiotics in animal feeds has been banned, researches on alternative natural products that modulate ruminal fermentation have been intensified. Natural compounds such as plant extracts have been considered to be replaced antibiotics as safe and sustainable alternatives. Plant extracts especially essential oils and saponins have strong antimicrobial, antiparasitic, antiprotozo...

Nutritional and health problems related to life style alarm European governments. The interest in school meals as a lever for change is increasing because young people reside longer in public institutions and their often unsatisfactory eating patterns might be counterbalanced by healthy school food. Organic food contributes to sustainable nutrition, and hence is an interesting starting point fo...
متن کاملIn situ Evaluation of Ruminal Degradability and Intestinal Digestibility of Sunflower Meal Compared to Soybean Meal
The aim of this study was to compare the nutritional value of sunflower meal (SFM) and soybean meal (SBM) protein by determining both its ruminal degradability and intestinal digestibility. Three non lactating Jersey cows fitted with a rumen and T-type duodenal cannulas were used to estimate rumen degradability and intestinal digestibility of SFM and SBM dry matter (DM) and crude protein (CP). ...
