in this research, effects of adding methafix (containing malate and fumarate as organic acids) with or without monensin in diet of fattening farahani lamb's on performance, and plasma concentration of some metabolites and minerals were investigated. twenty-four male lambs (4-6 months old, 35.9 ±7.4 kg) were randomly  assigned to; 1) control diet (control), 2) control with 24 mg of monensin...

The feed costs are the major expenses for farmers and main input that influenced economics of livestock production. physical form diet is one drivers better digestibility improved growth performance farm animals. This study aimed to evaluate effect using two different forms (ground mixtures pelleted mixtures) on fattening lambs. Seventy-two lambs were randomly assigned groups with 36 assess eff...

Objective: To evaluate the productive variables and digestibility of nutrients an integral diet for lambs with increasing inclusion Samanea saman pods.
 Design/methodology/approach: 24 creole (initial weight 20.6 ± 0.3 kg) distributed in a completely randomized experimental design were used. The treatments were: T1, 0%, T2, 12.5%, T3, 25% pod inclusion. evaluated compared Tukey test (? = 0...

Four years of grazing trials were conducted with Brassica forages to evaluate their chemical composition and effect on ADG of fattening lambs and breeding ewes in late fall. Brassicas tested included kales (Brassica oleracea L. var. acephala DC), turnips (B. rapa L.), and a chinese cabbage hybrid (B. rapa L. x B. pekinensis [Lour.] Rupr.). Daily gains of lambs varied widely among years (19 to 3...

the aim of the current study was to evaluate the replacement effect of soybean meal (sbm) at different levels (0 as d1, 33 as d2, 67 as d3 and 100% as d4 based on crude protein (cp) content) by guar meal (gm) on ruminal gas production kinetics, ruminal digestibility and fermentation characteristics of a fattening diet for lambs. three experiments were conducted. the first experiment of 144-h in...
