Cross-linking of lignin to arabinoxylan by ferulates limits in vitro rumen digestibility of grass cell walls. The effect of ferulate cross-linking on dry matter intake (DMI), milk production, and in vivo digestibility was investigated in ad libitum and restricted-intake digestion trials with lambs, and in a dairy cow performance trial using the low-ferulate sfe corn mutant. Silages of 5 inbred ...

this study was conducted to evaluate effects of rosemary essential oils (reo) on feed digestibility, blood and rumen parameters of ghezel sheep. four male sheep with average body weight 46±2 kg were used in a 4×4 latin square design. treatments composed of basal diet (control) in addition to diets containing 100 (ro100), 200 (ro200) and 400 (ro400) mg/day of reo.  sheep's fed with 4 diets ...

This study aims to determine the effects of inclusion waste sesame seed (WSS) concentrate feed on performance, carcass characteristics, and meat fatty acid profile Karayaka lambs. A total twenty-three lambs were randomly allocated a control group (11 lambs, with an average live weight 23.39±0.58 kg) experimental (12 23.55±0.41 kg). Also, each was divided into two subgroups according their gende...

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...

Four ruminally and duodenally cannulated Suffolk wether lambs (34.5 +/- 2.0 kg initial BW) were used in a 4 x 4 Latin square-designed experiment to examine the effects of ruminal protein degradability and supplementation frequency on site and extent of digestion in lambs consuming a low-quality forage diet. Wethers were fed a basal diet of mature crested wheatgrass hay (4.2% CP) for ad libitum ...

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...

Nutrient absorption is important in all stages of life. As the diet of an animal changes from birth on, morphological and biochemical adaptation can be anticipated in order to accommodate changing demands. The main focus of the present study was to examine the relationship between age and diet on the potential for peptide transport via PepT1 in the gastrointestinal tract of lambs and to relate ...

To examine the effect of supplementation varying levels oil Nigella sativa in Karadi lambs rations on nutrients digestibility, blood metabolites, and some rumen parameters, 18 were allocated into three groups, first group was fed a basal diet as control whereas, second (T2) third (T3) groups being supplemented with 0.15 0.30% DM (NSO) respectively. All animals individually 1.5 kg/lamb/day. Resu...

Five studies were conducted to determine nutrient digestibility and performance of lambs and steers fed thermochemically treated crop residues and distillers dried grains with solubles (DDGS) as a corn replacement pellet (CRP; 75% residue:25% DDGS, DM basis). Fifteen Hampshire, Suffolk, or Dorset wethers (BW 33.3 +/- 5.0 kg) were utilized to evaluate nutrient digestibility of the unprocessed na...
