Effect of fermented biogas residue on growth performance, serum biochemical parameters, and meat quality in pigs

Abstract

ObjectiveThis study investigated the effect of fermented biogas residue (FBR) of wheat on the performance, serum biochemical parameters, and meat quality in pigs.MethodsWe selected 128 pigs (the mean initial body weight was 40.24±3.08 kg) and randomly allocated them to 4 groups (1 control group and 3 treatment groups) with 4 replicates per group and 8 pigs per pen in a randomized complete block design based on initial body weight and sex. The control group received a corn-soybean meal-based diet, the treatment group fed diets containing 5%, 10%, and 15% FBR, respectively (abbreviated as FBR5, FBR10, and FBR15, respectively). Every group received equivalent-energy and nitrogen diets. The test lasted 60 days and was divided into early and late stages. Blood and carcass samples were obtained on 60 d. Meat quality was collected from two pigs per pen.ResultsDuring the late stage, the average daily feed intake and average daily gain of the treatment groups was greater than that of the control group (p<0.05). During the entire experiment, the average daily gain of the treatment groups was higher than that of the control group (p<0.05). Fermented biomass residue did not significantly affect serum biochemical parameters or meat quality, but did affect amino acid profiles in pork. The contents of Asp, Arg, Tyr, Phe, Leu, Thr, Ser, Lys, Pro, Ala, essential amino acids, non-essential amino acids, and total amino acids in pork of FBR5 and FBR10 were greater than those of the control group (p<0.05).ConclusionThese combined results suggest that feeding FBR could increase the average daily gain and average daily feed intake in pigs and the content of several flavor-promoting amino acids.

Partial Substitution of Fermented Soybean Meal for Soybean Meal Influences the Carcass Traits and Meat Quality of Broiler Chickens

“…The influences of fermented feed on the carcass traits and meat quality of pigs and poultry have been documented. Fermented biomass residue did not significantly affect the meat quality of pigs, but increased the essential, non-essential, and total amino acids in pork [15]. Fermented rapeseed cake had no effect on carcass dressing percentage or carcass fat content, but decreased the yield of breast muscle and increased the pH at 24 h postmortem, as well as the antioxidant status in breast muscle of turkey [16].…”

Potential of the polychaete Hediste diversicolor fed on aquaculture and biogas side streams as an aquaculture food source

“…Larval black soldier flies Hermetia illucens reared with biogas digestate showed results similar to ours: larvae grew on SBD, but flies fed high-quality diets (chicken feed) had 2 to 2.5 times higher gain in wet weight (Spran ghers et al 2017). Other studies have shown that pig feed can be supplemented with up to 15% of biogas sludge without any visible negative effects on pig growth rate, serum biochemistry or meat quality (Xu et al 2017). Thus, SBD can be used for a range of species, but can be im proved with the addition of other feed components.…”

Fermented Feed Modulates Meat Quality and Promotes the Growth of Longissimus Thoracis of Late-Finishing Pigs

“…Lee et al found that fermented apple pomace diet supplementation improved ADG (average daily gain) and feed efficiency in finishing pigs [14]. The results from Xu et al also showed that ADFI (average daily feed intake) and ADG were greater in finishing pigs fed fermented feed than those fed control diet [15]. However, Liu et al observed that dietary corn bran fermented by B. subtilis did not affect the ADFI and ADG of finishing pigs [16].…”
