Summary: The current study investigates the effects of micro-environmental variations on indigenous, Hampshire, and crossbred pigs. The results show that seasonal changes have significant impacts on the physiological, behavioral, and serum biochemical parameters of the pigs. Indigenous pigs demonstrate better adaptability to the changing climatic conditions compared to the other genotypes.

Summary: Long-distance transport in the global swine industry can adversely affect pigs, with winter journeys causing more stress response and impacts on meat pH due to abrupt variations in air temperature change and enthalpy rates. Developing new environmental control strategies to mitigate these effects is important to reduce the biological cost of long-distance transport on animals.

Summary: Cardiovascular disease is a major cause of morbidity and mortality worldwide. Stress tests are used to detect early signs of cardiovascular dysfunction or disease, such as in preterm birth cases. This study aimed to establish a safe and effective thermal stress test to assess cardiovascular function. Guinea pigs were anesthetized and various measurements were taken. A thermal stress test was developed with upper and lower temperature limits to ensure animal safety. This protocol provides a viable method for studying cardiovascular function in guinea pig models of health and disease.

Summary: In this study, magnetic carbon nanocomposites were successfully used for the removal of Cr (VI). The results showed that the magnetic adsorbents synthesized at high annealing temperature exhibited high magnetization for magnetic separation and large specific surface area for enhanced pollutant adsorption. The adsorption tests confirmed the ability of the synthesized nanostructures to remove Cr (VI), and the materials showed reusability after consecutive adsorption cycles.

Summary: The study examined the changes in the morphology and electrophysical properties of the Cr/n-Si (111) structure under different rapid thermal treatment conditions. Results showed that below 350 degrees Celsius, re-crystallization of the chromium films occurs with reduced grain sizes, specific surface energy and resistivity, while at temperatures between 400 and 550 degrees Celsius, diffusion synthesis of chromium disilicide leads to increased grain sizes, roughness parameters, specific surface energy and resistivity.

Summary: This study elucidates the role of harzianopyridone (HZRP) in alleviating chromium (Cr) stress in Vigna radiata. The results show that HZRP treatment enhances the net photosynthetic rate, stomatal conductance, and antioxidative enzyme activity, reducing growth inhibition and oxidative damage caused by Cr stress. Additionally, HZRP increases the levels of antioxidant metabolites and glycine betaine accumulation. These findings suggest the potential of HZRP in mitigating Cr stress.

Summary: Due to new environmental regulations, the use of hexavalent chromium electrolytes for chromium plating is no longer allowed. Trivalent chromium electrolytes have been developed as an alternative. This paper proposes a study on the adhesion of Cr-III coatings using numerical models and experimental scenarios. Two types of cracking, transverse cracking and delamination, were investigated. Microtensile tests and numerical simulations were conducted to analyze the damage initiation threshold and complete delamination of the coating.

Summary: The study investigated the mechanisms of Cr(VI) tolerance and reduction in the wild strain CM01 and its response to environmental pollution pressure at the molecular level. The iTRAQ technique identified differentially expressed proteins in domesticated CM01 related to Cr(VI) resistance. These findings were confirmed by RT-qPCR, showing consistency in gene expression levels. Additionally, domesticated CM01 displayed increased hydrophobicity, self-aggregation, glucose content, and SOD activity in response to Cr(VI) treatment.

Summary: The study shows that heat stress increases autophagy induction in oocytes during in vitro maturation (IVM), and artificially inducing autophagy can enhance oocyte maturation rate during IVM. These findings suggest that autophagy is a potential mechanism activated in oocytes during heat stress to recycle damaged cellular components and maintain developmental competence.

Summary: Pigs, especially the Mashen and Large White breeds, exhibit diverse transcriptional responses in skeletal muscle under cold stress. The Mashen pigs demonstrate stable physiological homeostasis and a strong immune response, while the Large White pigs primarily regulate heat production and energy metabolism. The PRSS8 gene plays a role in cellular energy metabolism and thermogenesis. These findings provide valuable insights into the molecular mechanisms underlying cold adaptation in pigs.

Summary: This study aimed to demonstrate that the nitrogen and energy in pig urine can be preserved by adding hydrochloric acid (HCl) and determine the minimum amount of HCl required for nitrogen preservation. The results showed that the addition of HCl can maintain the nitrogen concentration in urine and nitrogen is not volatilized at a pH below 5.12. An equation was developed to calculate the amount of HCl needed for nitrogen preservation in pig urine.

Summary: Protein digestibility is important for dogs as protein consists of essential amino acids. The digestibility of protein in dog diets can vary due to different formulations and nutrient compositions. This study developed prediction equations for estimating protein digestibility in dog diets. It was found that protein digestibility was negatively correlated with fiber contents. Overall, the protein and fiber concentrations in dog diets can be used to estimate protein and dry matter utilization.

Summary: This study investigated the effects of wheat bran on nutrient digestibility in pigs. The results showed that the digestibility of amino acids, lipids, and phosphorus decreased with increasing dietary wheat bran, while the digestibility of dry matter and organic matter increased. Additionally, the collection of ileal digesta did not significantly affect the fecal digestibility of nutrients. In conclusion, the inclusion of wheat bran reduced the digestibility of most nutrients but increased the hindgut digestibility of some nutrients, and the order of ileal digesta collection did not affect fecal nutrient digestibility.

Summary: The effects of supplemental mycotoxin-sequestering agents on the growth performance and nutrient utilization in growing pigs fed deoxynivalenol (DON)-contaminated diets were investigated in this study. The results showed that bentonite and yeast cell wall did not affect the growth performance of pigs, while a mixed product consisting of enzymes, microorganisms, minerals, and plant extracts partially alleviated the negative effects of dietary DON on the gain:feed ratio in pigs. Supplemental yeast cell wall decreased the calcium digestibility in pigs fed DON-contaminated diets, which needs to be considered in diet formulations.
