Megjegyzések:Study aimed to investigate the impact of long-term high ambient temperature (HAT) exposure and dietary antioxidant supplementation (elevated levels and in combination) on nutrient digestibility, metabolism and immune response of pigs. A total of 36 Danbred barrows (65.1 ? 2.81 kg) were allotted to four treatments: Trm1: HAT (28.9 ? 0.9 ?C) + control diet (CD); Trm2: HAT + elevated vitamin C and E and Se and Zn; Trm3: HAT + further elevated vitamin C and E and Se and Zn; and Trm4: thermo-neutral ambient temperature (19.5 ? 0.9 ?C) + CD. Nutrients (DM, CP, Cfat, CF, CA, GE) and minerals (Ca, P, Na, Zn, Se) digestibility were determined. Plasma metabolite and cytokine concentrations were investigated from the blood samples collected on d 15 and 28. Heat shock proteins (HSP 70 and 90) and tumor necrosis factor-alpha (TNF-?) expressions were investigated from jejunum samples of pigs. HAT did not significantly affect pigs' nutrient digestibility and retention (P > 0.05). However, Trm2 pigs had greater digestibility in terms of DM, CF, Ca, Zn, Se and retention of Ca, Zn, Na, and Se than Trm1 and Trm4 groups. Trm3 pigs had significantly higher (P < 0.05) creatinine concentrations than Trm4 pigs. HAT did not significantly affect the expression of cytokines; however, vitamins and micro-minerals supplementation in the diet significantly (P < 0.05) improved interleukin (IL) 10 expression, reduced TNF-?, and HSP70 expressions. Vitamin and micro-mineral fortified diet can improve pigs' nutrient and mineral digestibility and could alleviate inflammatory response in pigs exposed to HAT.

Cím:Effects of heat stress and high dietary antioxidant supplementation on the ileal digestibility of nutrients and certain minerals in pigs / Arth David Sol Valmoria Ortega, László Babinszky, Xénia Erika Ozsváth, Ogonji Humphrey Oriedo, János Oláh, Csaba Szabó
Dátum:2022
Megjegyzések:Heat stress (HS) can impair the pigs' intestinal integrity, jeopardizing their nutrient and mineral digestibility. Our study aim was to investigate HSs' impact on the ileal digestibility of nutrients and minerals in pigs and whether high dietary antioxidant (vitamins C, E, and micro-minerals Se, Zn) supplementation can improve their digestibility. Twenty-four Danbred barrows (65.1 ± 2.81kg) were distributed into four groups and placed in individual digestibility cages under thermo-neutral (TN) (19.5 ± 0.9°C) or HS (28.9 ± 0.9°C) room condition and fed with their respective dietary treatment (TN + control feed (TC); HS + control feed (HC); HS + elevated level dietary antioxidants (HT1); and HS + double elevated level of dietary antioxidants (HT2). Diets and ileal digesta were analysed for crude protein (CP), fat, fiber, ash, organic matter, NFE and minerals (Ca, P, Zn, Se, and Na). HS did not significantly affect the ileal digestibility of nutrients and minerals (P > 0.05). However, pigs on the HT1 treatment had significantly greater digestibility (P < 0.05) of CP, crude ash, Zn, Se, and Na than those on HC treatment. In conclusion, high genetic potential pigs can be resilient to HS adverse effects on the parameters studied. A high dietary antioxidant-fortified diet could improve pigs' nutrient and mineral digestibility under the HS challenge.

Cím:Effects of antioxidant supplementation on the growth performance of pigs exposed to heat stress / Arth David Sol Valmoria Ortega, László Babinszky, Xénia Erika Ozsváth, Ogonji Humphrey Oriedo, János Oláh, Csaba Szabó
Dátum:2021
Megjegyzések:Heat stress (HS) is a great consequence experienced by pigs when global temperature rises due to climate change. Production parameters such as growth is highly affected by this condition as the animal will be forced to perform physiological mechanisms in order to reduce metabolic heat and maintain euthermia of which is an important factor for the animals' optimal productive performance. In line with the capacity of antioxidants (organic source) to alleviate the adverse effects of HS, it is this research's aim to assess the effect of antioxidant (vitamins C and E, and minerals selenium and zinc) supplementation at elevated levels on the growth performance of pigs reared under HS conditions. Thirty-six Danbred barrows (65?70 kg) were allocated into four treatment groups, one group placed in thermal comfort (TC) (20 ?C) and the remaining groups (HC, HS1 and HS2) in HS condition (30 ?C). The pigs were fed with their respective diet; pigs in TC received basal feed (B) and in HS room, diets B (HC), elevated 1 (increased levels of antioxidants, HS1), and elevated 2 (further increased in antioxidant levels, HS2) were given in ad libitum. Measurements were performed weekly for four weeks, which comprised the adaptation (7 days, fed B diet), gradual temperature rise (heat increment, fed experimental diet) in HS room (7 days) and the experimental period (14 days). Body weight gain (BWG), average daily gain (ADG), feed intake (FI), and feed conversion ratio (FCR) were measured. All throughout the adaptation and heat increment period, pigs in all treatment have similar measurements. HS had no significant effect (P > 0.05) on the BWG, FI and FCR of pigs, numerically, however, HC pigs had the lightest BWG and were the least efficient feed converter among the treatment groups. Significantly lighter ADG (P < 0.05) was observed in HC pigs in the 2nd week of the experimental period, whilst not statistically, slight improvement in the ADG of pigs were observed upon the supplementation of antioxidants at HS1 level. Our results indicate that, in certain growth performance parameters, pigs with high genetic capacity can be resilient to the adverse effects of HS, and for those parameters that is greatly affected by HS, it can be slightly improved by antioxidant supplementation.

Cím:Effects of high vitamin and micro-mineral supplementation on growth performance and pork quality of finishing pigs under heat stress / Arth David Sol Valmoria Ortega, László Babinszky, Zsófia Rózsáné-Várszegi, Xénia Erika Ozsváth, Ogonji Humphrey Oriedo, János Oláh, Csaba Szabó

Megjegyzések: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 longissimus lumborum muscle was sampled to evaluate meat quality. At week four, HS significantly affected pig body weight (p < 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.

Cím:The Effect of Heat Stress and Vitamin and Micro-Mineral Supplementation on Some Mineral Digestibility and Electrolyte Balance of Pigs / Arth David Sol Valmoria Ortega, László Babinszky, Xénia Erika Ozsváth, Ogonji Humphrey Oriedo, Csaba Szabó

Megjegyzések:Simple Summary The deleterious effects of heat stress and its induced stressors on health and intestinal integrity may compromise the performance of pigs. Their physiological and behavioral mechanisms to promote thermoregulation can potentially influence electrolyte losses and compromise digestive capacity. The varied response exhibited by pigs under different durations of exposure to high ambient temperature led to our study on pigs and (1) the effect of the duration of heat stress on the digestibility of some minerals, (2) the balance of major electrolytes, and (3) the alleviation capability of vitamins and micro-minerals supplemented in combinations and at higher levels than recommended for pigs. Our results revealed that heat stress alone did not affect the digestibility of the minerals studied. However, supplementation of high levels of vitamins and micro-minerals improved the digestibility of some minerals, including calcium, selenium, and zinc, despite the exposure of the pigs to heat stress. Heat stress caused a significant reduction in the plasma chloride concentrations of pigs, which indicated an imbalance. Vitamin and micro-mineral supplementation corrected this issue. Heat stress (HS) can have detrimental effects on intestinal integrity and can jeopardize the digestibility performance in pigs. With prolonged exposure to heat, some thermoregulatory processes in pigs are potential causes for electrolyte imbalance. The adverse effects of HS on mineral digestibility and electrolyte balance are not widely studied and information on its abatement through vitamin and micro-mineral supplementation in combinations above the recommended level in pigs is limited. The aim of this study is to research this area. Thirty-six Danbred hybrid barrows (65.1 +/- 2.81kg) were distributed among the four treatments (n = 9 per treatment): (1) thermo-neutral (19.5 +/- 0.9 degrees C, RH- 85.9 +/- 7.3%)+ control diet (TC) (NRC, 2012), (2) HS (28.9 +/- 0.9 degrees C, RH- 60.4 +/- 4.3%) + control diet (HC), (3) HS +diet with elevated levels of vitamins (vitamin E and C) and micro-minerals (Zn and Se) (HT1), and (4) HS + diet with further elevation of vitamins and micro-minerals (HT2). Plasma samples were collected on days 7 and 21 of the experiment to investigate electrolyte concentration. During the experimental period, feces samples were collected from pigs placed in digestibility cages (six pigs from each treatment) to investigate the digestibility of Ca, P, Na, Se, and Zn. HS did not decrease the digestibility of minerals, but elevated supplementation of the selected vitamins and trace minerals improved it significantly. HS caused a significant decrease of Cl- (p < 0.01) in plasma, indicating an imbalance. In conclusion, pigs can have some resilience against heat stress in terms of mineral digestibility. Proper vitamin and trace mineral supplementation are key factors in the ability of pigs to overcome the negative effects of HS.
