“…The results showed seasonal influences on fat thickness, as animals incorporate more fat in autumn to protect themselves from the colder temperatures. Our results were consistent with previous reports, where the chronic heat stress during the finishing period (32 • C) resulted in back-fat thickness (−0.3 cm) compared with those maintained at the thermoneutral zone (21 • C) [29,30].…”

Most retailers in EU countries pay pig breeders for their animals’ lean meat percentage, which does not align fully with measures of pork quality (such as colour). In this study, we investigated the effects of season (summer vs. autumn) on finishing pigs’ performance, carcass characteristics, and meat quality parameters in 24 slaughter pigs. Growing performance traits (live weights, average daily weight gain), slaughter values (warm and cold carcass weights, trunk length, fat thickness) and meat quality parameters (pH at 45 min and 24 h postmortem, colour, drip loss, thawing loss, cooking loss, shear force, and meat composition) were recorded. Seasonal differences were more pronounced for the initial age, the number of days in the growing-finishing phase, and the average daily gain. There was also a significant difference in the trunk length between groups, the fat thickness on withers and loin, and also in mean fat thickness. A significant difference was found in the case of pH, total drip loss, and meat colour (L*). The intramuscular fat and collagen content of meat was significantly higher in summer; in contrast, the protein content of meat samples was considerably lower in summer. In conclusion, seasonal effects on finishers’ performance, lean meat values, and several meat quality parameters highlight the importance of more profound seasonal settings of climate control to fulfil the progressively changing quantitative and qualitative requests of pork sector participants from farm to fork.

“…Research has shown that adding PS to feed can effectively promote the synthesis of animal proteins, improve the reactive capacity of antioxidant enzymes in the blood, and exhibit good disease prevention and both control and reduce the cancer risk. Its high-dose use also rarely results in ad-verse toxic side effects (Wang et al 2020;Mun et al 2022). Plant sterols, as a common compound in plant feed, are widely present in plant-based foods such as grains and oilseed crops.…”

To better explore the effects of adding phytosterol (PS) microcapsules to feed on pig growth performance, nutrient apparent digestibility, and serum biochemical indicators, 200 healthy ternary hybrid Duroc × Landrace × Yorkshire piglets with an average initial weight of 7.53 ± 0.57 kg) were used as experimental subjects, and randomly divided into five groups with four replicates in each group. The control group of pigs was fed the basic diet, while the experimental group received diets supplemented with different PS levels. They were divided into experimental groups 1 to 4 (100 mg/kg to 5 502 mg/kg) according to different dosage added components. The duration of the experiment was 54 days. The results showed that the total triglyceride (TG) index and diarrhoea status in the experimental group were significantly improved compared to the control group (P < 0.05). The increase in PS addition levels was more significant in the change of pig average daily gain (ADG) (P < 0.05), and the difference in average daily weight gain and feed conversion ratio between PS-400 and PS-550 was significant (P < 0.05). Compared with the control group, the experimental group showed significant differences in crude fibre (CF), ether extract (EE), dry matter (DM), organic matter (OM), average digestible energy (ADE), metabolizable energy, xylan, and calcium (P < 0.05), with a maximum increase of 7.02% in calcium content. The addition of PS can be effective in making the experimental and control groups show a significant difference in value changes in high-density cholesterol (HDL-C) and low-density cholesterol (LDL-C) indicators (P < 0.05), while no significant changes were revealed in the other indicators (P > 0.05). From the above, plant sterol microcapsules can effectively improve pig growth performance and nutrient apparent digestibility, and improve their blood lipid status.

“…Regardless of the duration of exposure to high ambient temperature (AT), pig production parameters such as average daily gain (ADG), feed conversion ratio (FCR), and pork quality parameters are negatively affected (Song et al, 2011;Pearce et al, 2013;Morales et al, 2014;Yang et al, 2014a). Pigs exposed to HS at 30 °C have decreased pH value and increased crude fat, drip loss percentage, and toughness (Shear Force) of their meat (Yang et al, 2014a;Mun et al, 2022). Influence of HS on pigs' meat pH is critical as low pH can increase protein denaturation, resulting in decreased water holding capacity, lighter color, and subsequently poor eating quality (Kim et al, 2016;Jankowiak et al, 2021).…”

The objective of this study was to determine the effects of heat stress (HS) on the production performance of fattening pigs and whether the supplementation of vitamins (C and E) and micro-minerals (Se and Zn) at increased concentrations can mitigate HS adverse effects. Thirty six Danbred hybrid barrows (65.1 ± 2.81 kg) were randomly distributed into four treatments 1) HS (28.9 ± 0.9 °C, RH- 60.4 ± 4.3 %) + control diet (HC), 2) HS + diet 1 (HT1), 3) HS + diet 2 (HT2), and 4) thermo-neutral conditions (19.5 ± 0.9 °C, RH- 85.9 ± 7.3 %) + control diet (TC). Bodyweight and feed intake were measured weekly for four weeks. After the experiment, six pigs from each treatment were slaughtered, and the <em>longissimus lumborum</em> muscle was sampled to evaluate meat quality. At week four, HS significantly affected pig body weight (<em>p </em>< 0.05). However, the other parameters were not significantly affected by HS,while slight improvements in these parameters were observed by supplementing vitamins and micro-minerals in the diet of the pigs despite exposure to HS. Therefore, the pigs used in the study showed resilience to adverse effects of HS on growth and meat quality parameters. The content of vitamins C and E and microminerals Se and Zn in the diet seems to play an important role in resilience to HS, therefore their requirement and supplementation should be carefully evaluated.
