“…It seems that RSM and PS could totally replace SBM in sheep diets, despite the significant differences in their chemical composition (CP, NDF and ADF). Additionally, the present study revealed that OM digestibility of the RSM diet was 71.8%, a value similar to that of 73.2% reported by Eghbali et al (2011) for the same diet. Furthermore, Górka et al (2015) reported that replacing RSM and barley grain with high-lipid (9%) byproduct pellets in heifer diets affected total tract nutrient digestibility negatively.…”

The study determined the potential of eight locally produced protein sources to replace soybean meal (SBM) in the diet of sheep. Three in vivo digestibility trials were conducted using a Latin square (3x3, 4x4 and 4x4) experimental design with castrated Chios rams. The authors estimated nutrient digestibility coefficients and energy value of diets with soybean meal (control), lupin seeds (LS), rapeseed meal (RSM), sunflower meal (SFM), fababean seeds (FBS), vetch seeds (VS), pea seeds (PS), flaxseeds (FS), and chickpea seeds (CS). The results showed that the SBM, RSM, and PS diets had similar nutrient digestibility and energy value. The SFM diet had lower organic matter (OM) digestibility than the SBM diet. The FS and SFM diets had similar crude protein (CP) digestibility to the SBM diet. Additionally, FS, VS, and SBM diets had similar energy value. Furthermore, SBM, SFM, VS and FS diets had similar dry matter (DM), neutral detergent fibre (NDF), hemicelluloses, and cellulose digestibility coefficients. The SBM, LS, FBS, and CS diets had similar DM, OM, NDF, hemicelluloses, and cellulose digestibility coefficients. Additionally, SBM, LS, and CS diets had similar energy value. This study reveals that diets with RSM, PS, FS, and LS, compared with diets with SBM, did not have adverse effects on nutrient digestibility and energy value. These results tend to support the idea that some locally available protein sources seem to have the potential to replace SBM in sheep diets.

“…Therefore the ED value of DM, CP and OM in FS were lower than those of S significantly (p<0.05). Eghbali et al (2011) examined the effects of different treatment methods for canola meal on rumen degradability of CP and DM in in situ studies. The protein fraction was measured based on Cornell Net Carbohydrate and Protein system.…”

A series of in vitro studies were carried out to determine i) the effects of enzyme and formaldehyde treatment on the degradation characteristics of carbohydrate and protein sources and on the synchronicity of these processes, and ii) the effects of synchronizing carbohydrate and protein supply on rumen fermentation and microbial protein synthesis (MPS) in in vitro experiments. Untreated corn (C) and enzyme-treated corn (EC) were combined with soy bean meal with (ES) and without (S) enzyme treatment or formaldehyde treatment (FS). Six experimental feeds (CS, CES, CFS, ECS, ECES and ECFS) with different synchrony indices were prepared. Highly synchronous diets had the greatest dry matter (DM) digestibility when untreated corn was used. However, the degree of synchronicity did not influence DM digestibility when EC was mixed with various soybean meals. At time points of 12 h and 24 h of incubation, EC-containing diets showed lower ammonia-N concentrations than those of C-containing diets, irrespective of the degree of synchronicity, indicating that more efficient utilization of ammonia-N for MPS was achieved by ruminal microorganisms when EC was offered as a carbohydrate source. Within C-containing treatments, the purine base concentration increased as the diets were more synchronized. This effect was not observed when EC was offered. There were significant effects on VFA concentration of both C and S treatments and their interactions. Similar to purine concentrations, total VFA production and individual VFA concentration in the groups containing EC as an energy source was higher than those of other groups (CS, CES and CFS). The results of the present study suggested that the availability of energy or the protein source are the most limiting factors for rumen fermentation and MPS, rather than the degree of synchronicity.

“…The methods of Van Soest et al (1991) were used for the determination of neutral detergent fibre (NDF), which was assayed with a heat-stable amylase and expressed inclusive of residual ash. The soluble fraction of protein as the proportion of total protein (TP) in MSL was measured by a protein fractionation system (Licitra et al, 1996) with some modifications described by Eghbali et al (2011) in using phosphate buffer solution.…”

The present study was conducted to assess the inclusion of liquid protein feed (maize steep liquor; MSL) in growing lambs fed low-quality forage (400 g/kg wheat straw, dry mater basis) compared with two protein sources (soybean meal; SBM, and cottonseed meal; CSM). Eighteen male Farahani lambs, average body weight 36 ± 3.3 kg, were allocated to individual pens for 9 weeks. Three protein sources were: (1) MSL; (2) SBM and (3) CSM. Feed intakes did not differ among treatments. Growth rate and feed conversion ratio were improved in SBM-fed lambs. Nitrogen efficiency was improved in MSL v. CSM-fed lambs. Digestibility of fibre was enhanced in lambs fed SBM diet. Ruminal short chain fatty acid was highest in lambs fed SMB and lowest in lambs fed CSM. The urinary allantoin concentration was greater in SBM-fed lambs, with improved microbial crude protein synthesis. Blood urea nitrogen tended to be reduced in SBM-fed lambs. Dressing percentage improved in SBM-fed lambs. Lambs fed with SBM also grew faster and more efficiently than lambs fed either of the other two diets. However, regardless of the positive effects of SBM on the performance and ruminal fermentation profile observed in the current study, the MSL diet could be a profitable protein source in comparison to CSM in growing lambs fed low-quality forage. In conclusion, the present study indicates a positive outlook for feeding a liquid protein source to growing lambs fed low-quality forage such as wheat straw.
