Comparison of methods of in vitro dry matter digestibility for ten feeds.
The objectives were to determine if the in vitro dry matter (DM) digestibility was similar by using a traditional method compared to the new DAISYII system and to determine if in vitro DM digestibility was similar for sources of inoculum from two different donor cow diets, all forage or total mixed ration. Ten feeds were digested by the traditional method, the DAISYII method with same feeds in ...
متن کاملEstimation of Organic Matter Digestibility and Me Content in Ruminant Feeds from in Vitro Gas Production
17-79 ABSTRACT Cumulative gas production from incubation of feedstuffs with rumen liquor or a fresh faecal suspension as inoculum in vitro together with crude nutrient composition can be used to predict organic matter digestibility and metabolizable energy content of ruminant feeds with high accuracy. In this study, prediction equations were derived for roughages using 110 samples with known in...
متن کاملIn vitro Gas Production and Dry Matter Digestibility of Irradiated Pomegranate (Punica granatum) Seeds
The objective of this study was to determine the effect of irradiation of pomegranate seed (PS) on chemical composition, digestibility and kinetic of gas production. Pomegranate seeds were exposed to gamma ray (GR) and electron beam (EB) at doses of 5, 10, 15 and 20 kGy. Three ruminally fistulated rams were used for obtaining ruminal fluid for in vitro digestibility and gas production measuremen...
متن کاملDivergent Selection for In Vitro Dry Matter Digestibility in Switchgrass
The purposes of this study were to determine if phenotypic selection for in vitro dry matter digestibility (IVDMD) could be used to improve the IVDMD for switchgrass tPanicum virgatum L.) and to obtain heritability estimates of IVDMD in switchgrass. In 1973 a selection nursery of over 2,200 plants was established with transplanted seedlings of two similar Nebraska experimental strains. In 1974 ...
متن کاملMethods to study degradation of ruminant feeds.
Ruman degradation is crucial in the supply of dietary nutrients to meet the nutrient demands of the anaerobic microbes and body tissues of ruminant animals. Therefore, it is essential to study the dynamics of rumen degradation of various feeds before their potential use to formulate nutritious diets for ruminant animals. Amongst many methods that have been used in the past, the in sacco method ...
