“…In the current study, the increase of hay intake may have increased the passage rate as well as the time needed by rumen microbes to access substrates indicating the positive response on digestibility due to protein supplementation. However, other studies have reported that supplementation of protein has no effect on nutrient digestibility [17,19,20]. They attributed that to the low-quality forage source and small particle size of the ration ingredients.…”

The objective was to investigate the effect of supplementing Awassi lambs fed low-quality forage with soybean meal. Twenty-one lambs (initial body weight (BW) of 26.1 ± 2.57 kg) were randomly assigned to the study diets, 1) the basal diet (forage mix; CON; n = 7); 2) the basal diet supplemented with either 125 (SBM125; n = 7); or 3) with 250 (SBM250; n = 7) SBM g/head/day. The forage mix was composed of 65% wheat straw and 35% alfalfa hay. The experimental diet was offered to the animals for 54 days. On day 40, four animals from each group were chosen to assess N balance and nutrient digestibility. The intake of crude protein (CP) and dry matter (DM) was the highest (p < 0.016) in the SBM250 group, followed by the SBM125 group and the CON diet. Digestibility of DM and CP was higher (p <0.05) for the SBM-containing diets than the CON diet. Final BW and average daily gain were greater (p < 0.008) for lambs that consumed SBM-containing diets than for those that consumed the CON diet. In summary, the growth performance, forage utilization, and nutrient digestibility improved for lambs fed low-quality forage when supplemented with soybean meal.

“…Urea is a good source of NPN that can effectively be use as a source of supplemental N to ruminants consuming low-quality roughages with increasing of voluntary feed intake, nutrient digestibility, passage from the rumen, and rumen ecology (Cappellozza et al 2013;Sweeny et al 2014;Benedeti et al 2014;Holder et al 2015;Kang et al 2015;Ampapon et al 2016). Urea is used as the building block for the production of protein by rumen microbes, thus its comparable effects with other treatments.…”

“…Rumagen TM (Alltech) is a combination of slow release nitrogen source and highly digestible microbial protein source, due to its unique composition, this product meets both the nutritional and economical requirements. Urea additives were provided to meet 100% of the degradable intake protein requirement while soybean meal supplements were provided on an isonitrogenous basis by Cappellozza et al (2013). As suggested providing a urea-based supplement, was an effective alternative to a soybean based meal supplement in maintaining acceptable ruminal fermentation of steers consuming low-quality, cool-season forage.…”
