in order to investigate the effect of processing type (whole straw bale processing or opened straw bale processing with urea) on diet digestibility, economical and productive parameters in feedlot cattle, 18 holstein bull with average body weight 224.72 ± 20.45 kg were used in a completely randomized design with 3 treatments and 6 replicate. treatments 1, 2 and 3 contained 40% typical straw, 40...

Theexperiment was conducted to investigate the growth performance and feed conversion efficiency of crossbred heifer at different age level in Government Dairy Farm in Bogra, Bangladesh. Twelve female crossbred heifers were equally distributed (n=3) into four groups [Group A: (7±2 months), B: (12±2 months), C: (15±2 months) and D: (20±2 months)] according to age and fed concentrate mix, rice st...

Fertilizer N applied at ever-increasing rates sometimes accumulates in the soil. The practice of fertilizing grain straw with N to stimulate decomposition is questionable, but decomposition of straw immobilizes N that must be compensated for in fertilizing the succeeding crop. Too much N decreases the sucrose content of sugarbeets and decreases sucrose recovery. Experiments were conducted to de...

The anaerobic digestion of organic waste for biogas production can be affected by some variables such as temperature; concentration of the biogas feed solution, bacteria populations, and pressure. This study investigated the effects of thermal pretreatment at 50, 75, and 100 ºC on the biogas produced by simultaneous anaerobic digestion of cow manure, mushroom waste, and wheat straw at thermophi...

The goal of this study was to determine the comparative properties of dry-formed medium density fiberboards (MDF) made from renewable biomass (wheat and soybean straw) and those from conventional soft wood fiber. The MDF properties evaluated were modulus of elasticity, modulus of rupture, internal bond strength, thickness swell, and screw holding capacity. The results show that MDF made from wh...

this study was conducted to evaluate the effect of feeding treated wheat straw with urea and whey on fattening lambs performance. about 4.5 kg urea and 1.5 kg salt were dissolved in 40 l water and mixed with 30 l of whey. the solution was spread over 100 kg chopped wheat straw. thirty two male lambs were randomly divided into four feeding groups to compare performance with diets based on barley...
