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...

a solid state fermentation method was used to utilize wheat straw as substrates for citric acid production by using aspergillus niger atcc 9142. the plackett burman design (pbd) of experiments was used to test the relative importance of the variables affecting production such as moisture content, age of spore, inoculum size, initial ph of substrate, methanol concentration, incubation temperatur...

Twenty-four growing male buffalo calves (one year of age; 88.54 +/- 3.81 kg average body weight) were divided into three comparable groups (I, II and III) on the basis of their body weight (BW) in a completely randomised design to study the effect of long term feeding of ammoniated wheat straw (AWS) and hydrochloric acid treated ammoniated wheat straw (HCl-AWS) on blood biochemical changes. The...

The aim of this was to study the nutritive value of urea and corn grain treated wheat straw ensiled with cattle manure. The different levels of urea (0, 2 and 4%) and corn grain (2 and 4%) were used to treat wheat straw. The urea-corn grain treated wheat straw was mixed with cattle manure in the ratio of 70:30. The silages were fermented in laboratory silos for 20, 30 and 40 days. After the com...

An experiment was conducted with 24 Arabi lambs to investigate the possibility to increase the utilization of wheat straw by ensiling with urea at rate of 1.5 % as a nitrogen source and to get the advantage of the additional digestion caused by the released ammonia, and molasses at rate of 10 % to encourage the fermentation responsible for silage making. Straw silage (ES) was compared with whea...

The experiment was conducted to study the effect of treatment of rice straw with urea and a urease containing midden soil on the chemical composition of treated rice straw, feed intake of the animals, nutrients digestibility, body weight gain, feed conversion efficiency and overall economy of feeding for a period of 105 days. Twelve indigenous growing cattle (live weight 130.00±1.67 kg) were se...

The study was carried out to determine the effects of optimum cultureconditions (substrate to water ratio, incubation period and salt concentrations, e.g. MgSO4.7H2O, CaCl2, KH2PO4 and urea) to increase the nutritive value of wheat straw (WS) by solid-state fermentation (SSF) with Arachniotus species. The performance of SSF product was evaluated in terms of favorable change in the crude protein...

energy method of evaluation is widely employed in analyzing problems associated with sustainable agriculture. in this study, energy ratio (er) of dryland wheat for three regions of eghlid township was quantified. the total cropping area of eghlid is nearly 8282 hectares comprised of: khosrowshirin (5000 ha), sedeh (1682 ha) and dezhkord (1600 ha). the corresponding values of wheat yield in thes...
