The Effect of Medicinal Plants as a Feed Additive in Ruminant Nutrition
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...
متن کاملMicrowave irradiation of whole soybeans in ruminant nutrition: Protein and carbohydrate metabolism in vitro and in situ
Whole soybeans serve as one of the main sources of protein in ruminant nutrition. Different processing methods have been employed for ruminal protein protection. The present study was conducted to determine the effects of microwave irradiation [900 W; 2, 4 and 6 min] on quality, ruminal degradability and estimated in vitro intestinal digestibility of availability soybean crude protein....
متن کاملRuminant Livestock and Greenhouse‐Gases (A Nutritionist Perspective)
Greenhouse gases have been of serious global concern to environmentalists. Enteric ruminal fermentation and manure are seen to be responsible for global warming. Based on a better understanding of positive tan-nin effects on ruminant nutrition, the feeding value of browse trees and shrubs containing tannin, their roles on methanogenic rumen microbes in overcoming the production of enteric ferme...
متن کاملTechnical note: Bayesian calibration of dynamic ruminant nutrition models.
Mechanistic models of ruminant digestion and metabolism have advanced our understanding of the processes underlying ruminant animal physiology. Deterministic modeling practices ignore the inherent variation within and among individual animals and thus have no way to assess how sources of error influence model outputs. We introduce Bayesian calibration of mathematical models to address the need ...
