Abstract The objective of this study was to evaluate the effects of supplementing low-protein diets with sodium dichloroacetate (DCA) and glucose on growth performance, carcass traits, and meat quality of growing-finishing pigs. A total of 80 crossbred (Duroc × Landrace × Large White) growing barrows (27 ± 0.4 kg body weight) were allocated randomly to one of the five treatments during three successive 4-week periods. There were five diets in each phase. Diet 1 was the control diet with normal protein levels (CON) where protein levels in the three phases were 18%, 16.5%, and 15.5%, respectively. The dietary protein levels of Diets 2, 3, 4, and 5 (the low-protein diets, LP) were decreased by 4.5% compared to Diet 1. Additionally, Diets 3 and 4 were supplemented with an extra 120 mg/kg DCA (LP + DCA) or 1.8% glucose (LP + GLUC), respectively. Diet 5 was further supplemented with an extra 120 mg/kg DCA and 1.8% glucose (LP + DCA + GLUC). The LP + DCA diet increased the average daily weight gain of pigs compared to the CON and LP diet in phase 3 and the overall experimental period (P < 0.001). The LP diet reduced the gain:feed ratios of the pigs compared to the CON, LP + DCA, and LP + DCA + GLUC diets in phase 1 and the overall experimental period (P < 0.001). Furthermore, gain:feed ratios in LP + DCA and LP + DCA + GLUC groups did not differ from that of the CON group (P > 0.10). Pigs fed the LP + DCA diet had higher pH values of meat at 24 h post-mortem than the CON group (P < 0.05). The LP + DCA + GLUC diet increased the total protein content in the longissimus dorsi (LD) muscle of pigs, compared to the other dietary treatments (P < 0.05), and increased the Arg and Leu contents in the LD muscle compared to the LP + DCA diet (P < 0.05). Moreover, the LP + DCA diet induced a higher C18:1n9t percentage in the LD muscle of pigs compared to other groups (P < 0.05). In conclusion, an LP diet reduced the feed efficiency in pigs and barely affected meat quality, whereas 120 mg/kg DCA supplementation in an LP diet improved the growth performance of growing-finishing pigs, showed modest effects on carcass traits, and improved the muscle protein content with the addition of glucose.

Finishing Pigs

The objective of this study was to evaluate the efficacy of supplementing a corn-wheat-soybean meal-based diet with a multicarbohydrase and phytase complex (MCPC) on growth performance, apparent total tract digestibility (ATTD) of nutrients, carcass traits, and meat quality in growing-finishing pigs. A total of 300 pigs (Duroc × Large White × Landrace; body weight = 25.3 ± 0.7 kg) were randomly allotted to three groups with 10 replicates of 10 pigs each. Pigs from three groups were fed positive control (PC) or negative control (NC), without or with MCPC diets, respectively. The MCPC supplied at least 1800, 1244, 6600, and 1000 units of xylanase, β-glucanase, α-arabinofuranosidase, and phytase per kilogram of diet, respectively. The NC diet was the PC diet but reduced in net energy (NE), digestible amino acids (dig. AA), digestible P (dig. P), and Ca by 74 kcal/kg, 7.0%, 0.134, and 0.119 percentage points, respectively. The diets were fed in 4 growth phases based on body weight (BW): phase 1: 25–50 kg, phase 2: 50–75 kg, phase 3: 75–100 kg, and phase 4: 100–135 kg. Compared to the PC, the NC diet decreased (p < 0.05) body weight gain, feed intake, and(or) feed to gain ratio during the growing/finishing phases 1, 2, 3, and 4. It also reduced (p < 0.05) the ATTD of crude protein, crude fat, P, and Ca of pigs. MCPC supplementation improved (p < 0.05) the body weight gain, feed intake, and(or) feed to gain ratio in phases 2, 3, and 4 and the ATTD of crude protein, crude fat, ash, P, and Ca for the NC diet. Additionally, dietary treatment had no effects on carcass traits and meat quality with the exception that the loin eye area in the NC plus MCPC diet was higher (p < 0.05) than the NC diet. In conclusion, the addition of MCPC to a corn-soybean meal-wheat-based diet reduced in energy and nutrients improved the growth performance and nutrient digestibility but had little effect on carcass traits and meat quality in growing-finishing pigs.

Abstract Object: This study aimed to investigate the effects of Hermetia illucens larvae meal on growth performance, carcass traits, and meat quality of finishing pigs. Methods: Seventy-two crossbred (Duroc × Landrace × Large White) pigs (76.0 ± 0.52 kg) were randomly allocated to three experimental treatments, and fed the diet with supplementation of 0%, 4%, or 8% Hermetia illucens larvae meal (HILM), respectively. The experiment lasted 42 days. Results: The average daily gain (ADG) of pigs in 4% HILM group was higher, and the feed gain ratio (F/G) was lower than the control and 8% HILM group (P &lt; 0.05). The loin-eye area, marbling scores, and inosine monophosphate (IMP) content of Longissimus thoracis muscle (LM) in 4% and 8% HILM group were higher than the control group (P &lt; 0.05). There were no diffenences on backfat thickness, pH value, meat color, drip loss among three groups. Compared with the control, 4% HILM significantly increased the content of intramuscular fat (IMF) (P &lt; 0.05). Meanwhile, the mRNA expression level of fatty acid synthase (FAS), acetyl CoA carboxylase α (ACCα), lipoprotein lipase (LPL), and MyHC-IIa in the LM was higher in 4% HILM group than that in 8% Hermetia illucens larvae meal and the control group (P &lt; 0.05). The abundance of Lactobacillus, Pseudobutyrivibrio, Roseburia, Oribacterium, and Faecalibacterium was higher in 4% Hermetia illucens larvae meal group than the control group (P &lt; 0.05); The abundance of Streptococcus was lower and Peptococcus was higher in 4% HILM group than 8% HILM group. Conclusion: HILM can be used as an effective feed ingredient in finishing pig’ diet up to 4% level, which was beneficial for the growth performance, carcass trait, and meat quality of pigs, and the underlying mechanism maybe due to the altered lipogenic potential, myofiber characteristics and the microbial composition regulated by HILM.
