the nutritive value of grass pea (lathyrus sativus l.) hay was evaluated based on its chemical composition, gas production, fractioning of protein in cncps and afrc systems, metabolizable energy (me), rumen degradability through in situ technique and in vitro digestibility through tilley and terry method. the crude protein (cp), neutral detergent fiber (ndf) and acid detergent fiber (adf) value...

chemical assessments of forage clearly determine the forage quality; however, traditional methods of analysis are somehow time consuming, costly, and technically demanding. near infrared reflectance spectroscopy (nirs) has been reported as a method for evaluating chemical composition of agriculture products, food, and forage and has several advantages over chemical analyses such as conducting c...

Nineteen tanniferous browse plants were collected from South Africa to investigate their digestibility, gas production (GP) characteristics and methane production. Fresh samples were collected, dried in forced oven, and ground and analyzed for nutrient composition. In vitro GP and in vitro organic matter digestibility (IVOMD) were determined using rumen fluid collected, strained and anaerobical...

sixteen rams (mean age: 13 mo; mean live weight: 40.0 ± 2.4 kg) were randomly allotted to four dietary treatments in a completely randomized design (4 rams per treatment). diets (dry matter basis) contained 65% concentrate and 35% alfalfa hay (control diet, t1), 35% wheat straw (t2), 35% barley straw (t3) or 35% maize straw (t4). total-tract apparent digestibility for dry matter, organic matter...

This study was conducted to compare digestibility of wheat straw (WS) by fungi and whole rumen microorganisms (WRM). Dry matter (DM), neutral and acid detergent fiber (NDF and ADF) digestibility of WS were compared with in vitro digestion (IVD), gas production (GP) and specific rumen anaerobic fungi culture (SRAFC). Dry matter, NDF and ADF digestibility of WS by WRM of buffalo (60.80, 49.93 and...

The objective of this experiment was to evaluate the effects of adding cassava scrapings on gas and effluent losses, dry matter recovery, pH, contents of N-NH3, organic acids and volatile fatty acids and the bromatological composition of elephant grass silages. It was used a randomized complete design, with four levels of cassava scrapings (0, 7, 15 or 30% natural matter) each one with four rep...

A mixture of common Southern Piedmont (USA) grassland species (Lolium arundinacea, Paspalum dilatatum, Cynodon dactylon and Trifolium repens) was exposed to O(3) [ambient (non-filtered; NF) and twice-ambient (2X) concentrations] and fed to individually caged New Zealand white rabbits (Oryctolagus cuniculus) in a digestibility experiment. Forages and feed refusals were analyzed for concentration...

This study was conducted to determine the nutritive value of soybean varieties using in vitro methods and gas production technique.In vitro gas productions and gas production kinetics of soybean variety were determined at 0, 3, 6, 12, 24, 48, 72 and 96 h incubation times. This study revealed that there were variations among five different soybean varieties in terms of chemical...
