Growth and Nutrient Digestibility of Bull Calves: Basics, Methods, Future: Urea and Urease Treated Rice Straw

It is very profound to observe the zenith scarcity of qualitative and quantitative feedstuffs for feeding large numbers of animals in the world especially in South Asian countries like Bangladesh. Rice straw is the basal and most common feed lacking available energy, protein, minerals and vitamins reduces voluntary intake and rate of digestion. So, Extensive research carried out and prioritizes for improving nutritive value of cereal straws using physical, chemical and biological treatments and we are in the new era of different technologies for succession of new feeding systems as well as want to be a part of feeding standard that should be furnished for. This experiment was conducted to study the effect of treatment of straw with urea and urease sources. Successfully, I found that addition of chickpea and midden soil improved nutritive value of rice straw in terms of nutrient composition, digestibility, TDN value, body weight gain and meat yield, reduced the rearing cost of animals significantly. Therefore, I want to make scope and opportunity for those animal rearers who are struggled with the roughage feeding and looking for innovation in livestock development.
