Cím:The Role of Methionine Supplementation on Oxidative Stress and Antioxidant Status of Poultry-A Review / James Kachungwa Lugata, Arth David Sol Valmoria Ortega, Csaba Szabó
Dátum:2022
ISSN:2077-0472
Megjegyzések:The physiological status of poultry can be disturbed by different stressors that may lead to oxidative stress conditions. Oxidative stress activates defense systems, which mitigates the adverse effects. Several lines of the poultry defense system exist, including enzyme systems such as catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx), and non-enzymatic antioxidants such as Glutathione (GSH). Methionine-a vital amino acid in poultry nutrition-plays a significant role in protein synthesis, transsulfuration, and transmethylation and is also involved in several biochemical pathway activations that can affect the antioxidant system. Therefore, this review aims to summarize the current knowledge on the role of methionine in poultry under heat stress or managing stress, on the antioxidants responsible for scavenging free radicals (GSH) and those responsible for detoxification (SOD, CAT, and GPx). Different levels of methionine supplementation above the requirement (up to 1% Met added on the basal diet) have been tested on the antioxidant status of poultry. It has been shown to improve the antioxidant status and reduce oxidative stress. The results of many experiments on poultry supplemented with diets of different methionine sources indicate that L-Met has good potential to stimulate the antioxidant status of poultry.

Cím:Impact of heat stress length and dietary antioxidant supplementation on the nutrient digestibility, metabolism and immune response of fattening pigs / Arth David Sol Valmoria Ortega, László Babinszky, Ogonji Humphrey Oriedo, Brigitta Csernus, Xénia Erika Ozsváth, Levente Czeglédi, János Oláh, Csaba Szabó

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:Metabolism and endocrine alterations in growing and finishing pigs under different duration of heat stress - a review / Arth David Sol Valmoria Ortega, Csaba Szabó
Dátum:2023
ISSN:0860-4037
Megjegyzések:Pigs are less heat tolerant than other livestock species and are highly susceptible to heat stress (HS). HS is a physiological condition when an animal cannot release from its body excess heat caused by an increase in environmental temperature. Upon the pig's exposure to such conditions, their body activates several physiological and behavioral mechanisms to regulate its internal body temperature and maintain euthermia. The low thermolytic ability in pigs greatly impairs the aforementioned processes for self-regulation, having metabolic ramifications that can seriously affect the animal's productive performance and compromise its welfare. HS compromises the pigs' post-absorptive metabolism of carbohydrates, lipids, and protein by altering the use of body resources such as energy, fat, and protein. Although these consequences are evident under exposure to high environmental temperature, there is still an avenue for pigs to acclimatize, depending on the duration of exposure to such conditions. Therefore, this paper's objective is to review the influence of HS duration on the acclimatization of pigs and the metabolic consequences with emphasis on the changes in plasma biochemical compounds and hormones. A database search was used to gather information on the effect of HS duration on the plasma biochemical compounds and hormones. The collected data was then used to quantify changes in the levels of these substances as induced by HS duration. Our review showed that HS duration can influence the pigs' acclimatization to the said stressor; however, their metabolism was still compromised, as evidenced by changes in plasma biochemical compounds and hormones.

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 heat stress-induced oxidative stress on the reproduction of sows and its alleviation by dietary antioxidants: a review / Ortega Arth David Sol Valmoria, Xayalath Somsy, Lugata James Kachunhwa, Szabó Csaba
Dátum:2022
Megjegyzések:Sows are susceptible to high ambient temperature, and when it exceeds the level of their thermal comfort, they experience heat stress (HS). HS causes overproduction and accumulation of reactive oxygen species (ROS) in cells and can disturb the animals' antioxidant defense system, leading to oxidative stress (OS). Such stressor causes oxidative damage to proteins, lipids, polysaccharides, and DNA in cells and tissue damage. HS-induced OS also harms the sows' reproductive development. It can negatively affect the physiological process of the animals' reproduction from the maturation of oocytes to fertilization, development of the embryo, and pregnancy. It even extends to their reproductive performance. Although HS harms female reproduction, information regarding its induced stressor (OS) as the significant contributor to sows' reduced reproductive performance is limited. Therefore, this paper aims to review the effects of HS-induced OS on the reproductive performance of sows, and with due consideration to its nature, this work will also look into the effectiveness of dietary antioxidants against its adverse effects. Based on the literature, sows exposed to HS had increased plasma concentration of OS biomarkers (malondialdehyde, protein carbonyl, and 8-hydroxy-deoxyguanosine) and reduced activity of endogenous antioxidants, signifying OS. This resulted in reduced reproductive performance of sows, including lower litter weight at birth and a higher number of low birth weight piglets (higher variance) which causes high pre-weaning mortality. Moreover, the sows' colostrum, milk yield, and nutrient concentration are reduced upon exposure to the said stressor. Based on the information from various researches, dietary supplementation of antioxidants (vitamin C, E, and minerals Se and Zn) through the diet at various stages of sows' life could ameliorate HS-induced OS. Such amelioration can be supported by several researches which reported improvement in the sows' antioxidant status by increased activity of endogenous antioxidants (SOD, CAT, and GSH-Px) and subsequently improving their reproductive performance. Based on the information gathered, the enhancement of the antioxidant status and improvement of the sows' reproductive performance was exhibited when dietary levels of antioxidants are supplemented at high levels, suggesting the importance of regulating the dietary antioxidant levels in the diet upon HS challenge.

Cím:Effects of heat stress on the performance of primiparous and multiparous sows and their progeny : a review / Arth David Sol Valmoria Ortega, Csaba Szabó
Dátum:2022
Megjegyzések:High ambient temperature (AT) is a burden that can negatively influence the productivity of pigs. Highly prolific sows with high metabolic demands during gestation and lactation are sensitive to hot temperatures. High AT exacerbates their metabolic heat production during these stages of reproduction, and they can suffer heat stress (HS). Considering the possibility of varied responses of sows at different parity to HS, this paper aims to review the effects of gestational HS on the reproductive performance of primiparous and multiparous sows. Concerning the possible difference in their performance, this paper will also look into the production performance of their progeny. Based on the reviewed manuscripts, gestational HS experienced by sows at any time of gestation can negatively affect their reproductive performance. Primiparous and multiparous sows' response to gestational HS differs, with the former having been highly affected by the stressor. Primiparous sows are less capable of thermoregulation upon HS challenge and greatly suffer from its reproductive consequences. The impact of HS was also observed in the production performance of their offspring. The growers and finishers born from primiparous sows had lighter average daily gain and were less efficient in converting feed into body weight gain, respectively, than the offspring of multiparous sows. Nevertheless, offspring from both parities responded with similar carcass quality. Although we reviewed these differences, the lack of research on this topic limits our information on the progeny's production performance differences at the weanling stage. Therefore, further research in this area is needed.

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:Impact of chronic heat stress on the digestibility and retention of nutrients in finishing pigs / Arth David Sol Valmoria Ortega, László Babinszky, Ogonji Humphrey Oriedo, Csaba Szabó
Dátum:2020
Megjegyzések:Heat stress (HS) compromise intestinal integrity of pigs which can result to poor nutrient digestibility and retention. The aims of the current study was to assess how chronic HS impacts the digestibility and retention of nutrients in finishing pigs and whether supplementing them with two levels of vitamins E and C and minerals Zn and Se (organic source) can help mitigate its adverse effects. Twenty-four Danbred hybrid barrows weighing 65-70kg were distributed into four different treatments (three pens per group) which were placed in thermo neutral condition (20?C) and heat stress (30?C) condition and fed with their respective dietary treatment. Pigs in the thermo neutral room received only basal feed (TC) and in heat stress room one group received the control feed (HC), the next group received increased vitamin and mineral supplementation (HT1), and the last treatment group received a further increased vitamin and mineral supplementation (to double the difference between HT1 and HC (HT2)). Diets were fed ad libitum. Two times three pigs from each treatment group where placed in individual digestibility cages in 2 batches. The experimental period lasted for 9 days (two days adaptation to the cage and 5 days collection). Collection of feces, urine and feed residue was done daily and sampled for analysis. HS did not affect significantly the nutrient digestibility and retention of pigs (P > 0.05). However, pigs fed elevated levels of antioxidants (HT1) had greater digestibility and retention of some nutrients compared to HC and TC groups, despite being exposed to high ambient temperature. Further increase in the level of antioxidant supplementation (HT2) did not improve the digestibility and protein retention of pigs. Thus, it is important to carefully evaluate the level of vitamin and mineral requirements of pigs as well as its supplementation and pigs with high genetic capacity can be highly resilient against the adverse effects of HS.

Cím:Metabolic response of growing and finishing pigs under different duration of heat stress - a review / Ortega Arth David Sol Valmoria, Szabó Csaba
Dátum:2021
Megjegyzések:Pigs are less heat tolerant than other livestock species and are highly susceptible to heat stress (HS). HS is a physiological condition when an animal cannot release excess heat from its body caused by an increase in environmental temperature. Upon the pigs' exposure to such conditions its body performs several physiological and behavioral mechanisms to regulate its internal body temperature and maintain homeothermy. Pigs have a low thermolytic ability, which significantly affects the said mechanisms for self-regulation. This can lead to metabolic consequences that can dramatically jeopardize the animals' productive performance. HS compromises the pigs' post-absorptive metabolism of carbohydrates, lipids and protein by altering the use of its body resources such as energy, fat and protein. Although these consequences are evident under high exposure to environmental temperature, there is still an avenue for pigs to acclimatize and it can be influenced by the duration of exposure to such condition. Our review gathered significant findings from several research pieces regarding the different periods of HS's effects on the pigs' metabolism. We discovered that several biochemical parameters and hormones that are essential for the pigs' metabolism have a varied response to the duration of the animals' exposure to HS. Pigs' blood glucose concentration spiked up upon acute exposure to HS. Still, prolonged exposure led to its reduction causing negative energy balance. It can force the animal to use its body's glycogen through glycogenolysis. Furthermore long-term HS exposure increased the levels of low density lipoprotein cholesterol and triglycerides. Contrastingly, concentrations of high density lipoprotein cholesterol were decreased, leading to greater pig carcass fatness. An increase in cortisol level was also evident regardless of HS exposure duration, which affects insulin's function in facilitating protein synthesis in muscles. Thyroid hormones: Triiodothyronine (T3) and Thyroxine (T4), however, had varied responses. The T3 highly decreased at 8 days of HS exposure. Still, it gradually increased over time (21days), while T4 had a constant decrease from 1st week to 3rd week of HS exposure. Therefore, pigs' metabolism is compromised regardless of the HS exposure duration and immediate intervention strategies should be applied to alleviate such adverse effects.

Moreover, the sows' colostrum, milk yield, and nutrient concentration can be reduced upon exposure to the said stressor, demanding an efficient mitigation strategy. Understanding the sows' reproduction and HS-induced OS influence on its viability is vital in providing proper mitigation strategy. Therefore, this paper aimed to review the female pigs' reproductive development, the impact of HS-induced OS on their reproduction, and the possible alleviation of its adverse effects by dietary antioxidants. Based on the information from various researches, antioxidant fortified diet fed to sows at various stages of life could ameliorate HS-induced OS. Several researches have confirmed this by improving the sows' antioxidant status as supported by increased activity of endogenous antioxidants (SOD, CAT, and GSH-Px) and subsequently improving their reproductive performance. Based on the information gathered, the enhancement of the antioxidant status and improvement of the sows' reproductive performance was exhibited when dietary levels of antioxidants are supplemented at high levels, suggesting the importance of regulating the dietary antioxidant levels in the diet upon HS challenge.
