Abstract
The quality of pork determines consumers' purchase intention, which directly affects the economic value of pork. Minimizing the proportion of inferior pork and producing high quality pork are the ultimate goals of the pig industry. Muscle energy metabolism, serving as a regulative hub in organism energy expenditure and storage as a fat deposit, is compatible with myofiber type composition, affecting meat color, intramuscular fat content, tenderness, pH values and drip loss. Increasing data illustrate that dietary nutrients and bioactive ingredients affect muscle energy metabolism, white adipose browning and fat distribution, and myofiber type composition in humans, and rodents. Recently, some studies have shown that modulating muscle energy metabolism and lipid accumulation through nutritional approaches could effectively improve meat quality. This article reviews the progress and development in this field, and specifically discusses the impacts of dietary supply of amino acids, lipids, and gut microbiota as well as maternal nutrition on skeletal muscle energy metabolism, lipid accumulation and meat quality of pigs, so as to provide comprehensive overview with respect to effective avenues for improving meat quality.

Foods 2022; 11:foods11213335. [PMID: 36359950 PMCID: PMC9656922 DOI: 10.3390/foods11213335] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2022] [Revised: 10/07/2022] [Accepted: 10/19/2022] [Indexed: 11/25/2022] Open
Abstract
L-malic acid is a vital intermediate in the citric acid cycle and has been reported to improve the antioxidant capacity and aerobic oxidation of weaned piglets; however, its application in finishing pigs is limited at present. This study explored the effects of dietary L-malic acid supplementation on the carcass traits and meat quality of finishing pigs. In a 45-day experiment, 192 Duroc × Landrace × Yorkshire pigs (75.01 ± 0.51 kg) were divided into four treatments, i.e., a basal diet supplemented with 0, 0.5%, 1%, and 2% L-malic acid complex. The results showed that L-malic acid supplementation had no effects on the growth performance of finishing pigs. Importantly, L-malic acid significantly increased redness (a*) value at 24-h postmortem (quadratic, p < 0.05) and tended to increase the proportion of oxymyoglobin (OMb) (quadratic, p = 0.10), as well as the total antioxidant capacity (T-AOC) activity (quadratic, p = 0.08) in the longissimus dorsi (LD) muscle. Further, dietary supplementation of 1% L-malic acid markedly increased the protein expression level of slow skeletal myosin heavy chain (MyHC) in the LD muscle (p < 0.05). Moreover, 0.5% and 2% L-malic acid supplementation significantly increased carcass length and loin eye area (p < 0.05). In conclusion, dietary L-malic acid could effectively improve the meat color and carcass traits of finishing pigs.

Effect of maternal dietary starch-to-fat ratio and daily energy intake during late pregnancy on the performance and lipid metabolism of primiparous sows and newborn piglets. J Anim Sci 2022; 100:6562286. [PMID: 35363312 PMCID: PMC9030130 DOI: 10.1093/jas/skac033] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2021] [Accepted: 02/03/2022] [Indexed: 12/13/2022] Open
Abstract
The present study evaluated the effects of maternal dietary energy intake and starch-to-fat ratio during late gestation on the performance and lipid metabolism of sows and their offspring. On day 84 of gestation, 80 Landrace × Yorkshire primiparous sows were assigned to 2 × 2 factorial arrangements according to body weight following a randomized complete block design. The factors were daily energy intake (8,375 kcal ME/d [CE] vs. 9,600 kcal ME/d [HE]) and dietary starch-to-fat ratio (10:1 [CR] vs. 15:1 [HR]). All sows were fed one of four diets from day 85 of gestation until farrowing. Data were analyzed using the GLM procedure in SPSS. High energy intake increased the body weight of sows on day 110 of gestation (P = 0.031) as well as the weight of piglets at birth (P = 0.018). Increased energy intake elevated the plasma triglyceride concentrations in sows (P = 0.027) and piglets (P = 0.044). Maternal high energy intake altered the liver metabolome of newborn piglets in terms of metabolites related to carbohydrate and linoleic acid metabolism. Moreover, maternal high energy intake increased hepatic total cholesterol (P = 0.023) and triglyceride (P = 0.026) concentration in newborn piglets. Furthermore, maternal high energy intake significantly increased the transcript abundance of fatty acid synthase (FAS; P = 0.001) and protein abundance of phosphorylated protein kinase B (P =0.001) in the liver of newborn piglets. A high starch-to-fat ratio reduced low-density lipoprotein cholesterol (LDL-C) concentration in the plasma of sows (P = 0.044) and newborn piglets (P = 0.048) as well as in the liver of newborn piglets (P = 0.015). Furthermore, maternal high starch-to-fat ratio increased the transcript abundances of FAS (P = 0.004) in newborn piglets. In conclusion, high daily energy intake of sows increased the birth weight of newborn piglets. Moreover, maternal high daily energy intake and high dietary starch-to-fat ratio improved the lipid metabolism of newborn piglets.

Abstract
Maternal sodium butyrate (SB) intake has important effects on offspring growth and development. This study aimed to investigate the impacts of maternal SB supplementation during gestation and lactation on fatty acid composition and lipid metabolism in the offspring skeletal muscle of pigs. Twenty sows (Yorkshire, parity 2 to 3) were assigned to the control group (diets without SB, n = 10) and SB group (diets with 0.1% SB, n = 10). The results showed maternal SB supplementation throughout gestation and lactation increased (P < 0.05) body weight of offspring piglets at weaning. The concentrations of triglyceride in plasma and milk were enhanced (P < 0.05). Maternal SB induced (P < 0.05) lipid accumulation with increased expression of peroxisome proliferator activated receptor γ (PPARγ) by enrichment of the acetylation of H3 acetylation K27 (H3K27) in offspring skeletal muscle. Meanwhile, the concentrations of C18:2n-6, C18:3n-3, total polyunsaturated fatty acid (PUFA), n-6 PUFA and n-3 PUFA decreased (P < 0.05) in skeletal muscle of weaning piglets derived from SB sows. Together, these results showed that maternal SB supplementation could influence offspring growth performance, lipid metabolism and fatty acid composition of the skeletal muscle.

Meat Sci 2015; 108:82-7. [PMID: 26047981 DOI: 10.1016/j.meatsci.2015.05.027] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2014] [Revised: 05/25/2015] [Accepted: 05/26/2015] [Indexed: 01/05/2023]
Abstract
To investigate the influence of maternal dietary fat intake on the fatty acid composition and lipid metabolism of progeny subcutaneous fat (SQ), fourteen sows were randomly assigned to a control or high fat (HF) group which received a diet containing 8% corn oil starting seven days before farrowing until weaning. The results showed the fatty acid composition in progeny SQ at weaning age generally demonstrated a similar pattern with the sow milk. However, this pattern was not observed at the finishing stage. The stearoyl-CoA desaturase 1 mRNA and protein levels in the progeny SQ of the HF group decreased at both sampling stages when compared with controls. The study demonstrated that maternal dietary fat during lactation significantly affected the fatty acid composition of progeny SQ at the weaning stage, yet no obvious lasting effect was observed in progeny SQ at the finishing stage.
