Effect of bitter vetch (Vicia ervilia) seeds as a replacement protein source of soybean meal on performance and carcass characteristics of finishing Awassi lambs

Abstract One-hundred twenty crossbreed steers (initial body weight (BW) 566 ± 42 kg) were used to evaluate the interaction of protein source (PS) and non-roughage NDF content (NRFC) in finishing diets of feedlot cattle fed free-choice hay on performance and carcass characteristics. Steers were stratified by BW and randomly assigned to 8 pens (2×2 factorial) and fed for 104 ± 10 d. Four dietary treatments were investigated: 1) distillers’ dry grains with solubles (DDGS) and a low NRFC (DLF), 2) DDGS and a high NRFC (DHF), 3) soybean meal (SBM) and a low NRFC (SLF), 4) SBM and a high NRFC (SHF). Free-choice grass hay and concentrates were offered in a different bunk. Data were analyzed as a randomized complete block design. Do to the confounded effect of PS and protein intake, a linear regression was used to evaluate the effect of protein intake in growth performance. For gain to feed ratio (G:F) an interaction tended to occur (P = 0.10) between PS and NRFC. Steers on the DHF treatment had a lower G:F compared with SLF and SHF. Feeding SBM increased (P = 0.05) final BW, tended to increase (P = 0.06) average daily gain (ADG), and decreased (P = 0.05) hay intake (HI) compared with steers fed DDGS. There was a positive association (P ˂ 0.01) of crude protein intake with ADG and FBW. Dietary NRFC did not change (P ≥ 0.3) final BW, ADG, DMI, and HI. Protein source did not affect (P ≥ 0.16) hot carcass weight (HCW), longissimus muscle (LM) area, dressing, 12th rib fat thickness, or marbling score (MS). No differences were detected between NRFC for dressing, HCW, LM area, or MS (P ≥ 0.18); but diets with greater NRFC decreased (P = 0.03) the 12th rib fat thickness. Steers in the SHF treatment presented the lesser kidney-pelvic-heart fat compared with the remaining treatments (PS×NRFC interaction, P = 0.04). Soybean meal inclusion/increase in protein intake improved growth performance of feedlot steers compared with DDGS, despite protein intake meet the protein requirement. Increasing the NRFC did not affect growth or HI but decreased feed efficiency of steers fed DDGS.

The Impact

Abstract Two experiments were conducted to evaluate corn dried distiller’s grains with solubles (DDGS) and corn gluten feed (CGF) as replacements for soybean meal (SBM) and determine the impact of an ionophore on Boer goat growth performance and carcass characteristics. In Exp. 1, 75 Boer-goat kids (initial BW 26.9 ± kg) were allotted to one of 5 dietary treatments: 1) Negative control (100% SBM, 0% DDGS and 0% CGF; 100SBM); 2) Positive control (100% DDGS, 0% CGF and 0% SBM; 100DDGS); 3) 66% DDGS, 33% CGF and 0% SBM (66DDGS/33CGF); 4) 66% CGF, 33% DDGS and 0% SBM (33DDGS/66 CGF); and 5) 100% CGF, 0% DDGS and 0% SBM (0DDGS/100CGF). Dietary treatment did not impact (P ≤ 0.21) growth. In Exp. 2, 72 Boer-goat kids (initial BW 21.7 ± kg) were allotted to one of 4 dietary treatments in a 2 X 2 factorial with 2 protein sources and 2 ionophore inclusions: 1) SBM/no ionophore (SBM-NI); Diet 2) SBM with ionophore (SBM-I); Diet 3) DDGS/no ionophore (DDGS-NI); and Diet 4) DDGS with ionophore (DDGS-I). On d 21, goats were split into 2 groups according to their protein source and fed an additional d 10 (Group 1: DDGS-I; Group 2: SBM-I). The 15 heaviest goats from each group were harvested and carcass data collected. The protein source X ionophore interaction was not significant (P ≥ 0.15) for any measured response criteria. Goats fed a diet with SBM had significantly increased (P = 0.04) ADG compared to goats fed DDGS. No evidence of difference was observed (P ³ 0.10) for ADFI or G:F. Dietary treatment did not impact (P > 0.05) carcass characteristics. In summary, these data suggest that corn co-products can be economically included in Boer-goat diets, however their impact on growth performance is variable compared to that of soybean meal.

Engineering Sciences

The fish meal and soybean meal are the most used protein sources in poultry rations, especially in quail birds due to their higher requirements of crude protein that affecting their growth rate. The objective was to investigate the effect of source of dietary protein and its levels on growth traits, carcass characteristics and some blood parameters. This study was conducted at poultry farm in Duhok city/College of agricultural engineering sciences/Animal production Department/ Kurdistan Region- Iraq, 2020. A total of 360 one-day unsexed chicks of J. quail (Coturnix Coturnix Japonica) were divided equally into two groups (treatments) according to protein source (fishmeal and soybean meal groups), each group involved three levels of crude protein (20, 23 and 26 % CP), and each level had three replicates. The birds distributed randomly on the cages which contained 20 birds / replicate. The main results were as follow; fishmeal source of diet protein surpassed significantly soybean in live body weight (LBW), weight gain (WG), feed conversion ratio (FCR) and carcass characteristics. The level of 26 % crude protein (CP) in the diet recorded the best LBW, WG and FCR; while the level of 23 % CP surpassed both 20 % and 26 % in mortality rate and carcass dissections. However, total protein, hemoglobin and albumen parameters in the blood were not affected significantly (p>0.05) neither by protein source nor by its levels in the quail rations. As conclusion, fish meal was better than soybean meal; and 26 % CP was the best level.
