Warmth stress negatively impacts animal efficiency, primarily by decreased feed consumption, which results in decrease common every day acquire and decreased feed effectivity. Warmth stress additionally causes nutrient utilization shifts, osmotic stress, and gastrointestinal points, impairing digestion and nutrient absorption. Feeding methods, together with food regimen composition adjustments and useful feed components, have the potential to mitigate warmth stress results. Antioxidants, reminiscent of vitamin E, vitamin C, and selenomethionine assist alleviate oxidative stress, whereas betaine features as an osmoprotectant. Though particular person components have been studied, the mixed impact of vitamin E, vitamin C, selenomethionine, and betaine throughout warmth stress in pigs stays unexplored.
Goal: The intention of the current research was to analyze the impact of dietary supplementation of betaine, vitamin E, vitamin C, and selenomethionine in rising–ending pigs below summer time circumstances.
Strategies: Sixty pigs had been divided into two teams: the management (CF) and summer time feed group. The trial started on 30 June 2021 with pigs at 10 weeks of age (31.0 ± 2.9 kg) and concluded on 12 October 2021 at 25 weeks of age when the pigs reached slaughter weight (120.6 ± 11.3 kg). The summer time feed group obtained a food regimen enriched with selenomethionine, nutritional vitamins E and C, and betaine below authorized limits. Key parameters, together with respiration fee, rectal and pores and skin temperature, conduct, weight acquire, and water consumption, had been monitored.
Outcomes: The summer time feed group confirmed much less improve in water consumption throughout warmth stress, whereas each teams skilled larger respiration charges and pores and skin temperatures throughout warmth waves.
Conclusion: These findings counsel that the enriched food regimen could cut back the necessity for elevated water consumption throughout scorching intervals and spotlight the sensitivity of pigs to warmth stress, significantly by adjustments in respiration charges and pores and skin temperatures.
