Feed is the largest single cost of producing beef. Producers who have access to alternative feeds often have economic advantages due to the lower costs of production. However, alternative feeds can present challenges due to variable consistency, variable supply, potential toxicants, and unusual composition. Rice straw, a by-product of the rice grain industry in Northern California, is a potenti...

Several foods are available for the formulation of rations in Brazil; however, effectiveness a few these has been evaluated diets bullfrog tadpoles (Lithobates catesbeianus). This study aimed to evaluate alternative (worm meal, peeled banana, pumpkin, and avocado) with different levels crude protein ether extract nutrition obtain best animal performance water quality. In 60 days long experiment...

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...

Background Fed-batch culture bioprocesses are essential for the production of therapeutic proteins [1]. In these cultures, concentrated feeds are added during cultivation to prevent nutrient depletion and to extend the growth phase, thus increasing product concentration [2]. One limitation arises from the low solubility of some amino acids at high concentrations, in particular tyrosine [3]. Thi...

Considering choline (ChCl) as an essential ingredient for animals and that it is administered through feed, we developed an easy, accurate, and sensitive method for its analysis. The method is straightforward, derivatization-free and has no secondary chromatographic interactions. •We demonstrated that the method can be used for quality control for feeds and feed additives containing choline chl...
