چکیده
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 selected and divided into four groups having three animals in each group. the animals received 3.0% urea + 2.0% midden soil treated rice straw (group a), 3.0% urea + 3.0% midden soil treated rice straw (group b), 3.0% urea + 4.0% midden soil treated rice straw (group c) and 3.0% urea + 5.0% midden soil treated rice straw (group d). in addition, all the animals were supplied with 2 kg green grass, 450 g concentrate mixture and 40 g salt per 100 kg body weight. treatment of rice straw with 3.0% urea+ 2.0% midden soil lead to an increase in crude protein content from 3.30 to 7.08%, which was further increased by 7.40, 7.90 and 8.14% if treated with 3.0% urea + 3.0% midden soil, 3.0% urea + 4.0% midden soil and 3.0% urea + 5.0% midden soil, respectively. the total live weight gain by the end of the experimental period (105 days) was 39.00, 42.50, 46.50 and 49.00 kg for groups a, b, c and d respectively. the addition of 5.0% midden soil as a urease source with 3.0% urea (d) treated rice straw not only significantly (p

متن کاملFeeding Rice Straw to Cattle
Feed is the largest single cost of producing beef. Producers who have access to alternative feeds often have economic advantages due to the lower costs of production. However, alternative feeds can present challenges due to variable consistency, variable supply, potential toxicants, and unusual composition. Rice straw, a by-product of the rice grain industry in Northern California, is a potenti...

Incorporation of plant residues in soil affects N and C content and dynamics. This studydetermined the effects of short-term alternative rice (Oryza sativa L.) residue management on Nmineralization and uptake by rice. Pot and laboratory incubation experiments were established byincorporating 15N-labeled rice straw and rice straw compost in paddy soil. The 15N recovered by riceaveraged 16.6%; mo...
