Livestock farming has a detrimental effect on the environment since it generates a lot of gas emissions. In pig farming, the use of feed is among the substantial sources of animal farm emissions among the European Union. Nevertheless, the use of Low Dietary Crude Protein (LCP) may reduce the environmental impacts of pig farming and provide diverse ecosystem services (ESs). Concurrently, these pig diets alternatives may result more expensive than the conventional ones, which may negatively affect farmers' intention to adopt these alternatives. Citizens' payment for ESs may be a viable strategy to motivate farmers to implement more sustainable pig diets. The primary objective of this study is to assess the extent to which citizens of Catalonia (Spain) are willing to pay for the ESs generated by the implementation of a LCP diet in pig production. In pursuit of this goal, we conducted an online survey among 501 citizens, including a Discrete Choice Experiment. Participants evaluated three feed scenarios, and their choices were scrutinized using conditional logit model. Results revealed that citizens prefer the new pig diets, including both LCP and Very LCP (VLCP) diets, over the conventional pig diet. However, there is a clear preference toward the VLCP diet justified by their willingness to pay (WTP) of €67/year/adult.

Effects of multienzyme supplementation on energy and nutrient digestibility in various feed ingredients for pregnant gilts.

The utilization of exogenous fiber-degrading enzymes in commercial swine diets is a strategy to increase the nutrient and energy density of poorly digestible ingredients. In a prior set of studies, dietary multienzyme blend (MEblend) supplementation increased the apparent total tract digestibility (ATTD) of nutrients, non-starch polysaccharides, and energy in complete high-fibrous gestation diets by 6% when fed to gestating sows. The current study aimed to determine the effects of MEblend (containing xylanase, β-glucanase, cellulase, amylase, protease, pectinase, and invertase activities) supplementation on ATTD of energy and nutrients of individual feedstuffs commonly used in gestating sow diets across major pork-producing regions worldwide, which differ in their fibrous components.

Unlabelled: Although metagenomic investigations into microbial fiber-degrading capabilities are currently prevalent, there is a notable gap in research concerning the regulatory mechanisms underpinning host-microbiota interactions that confer tolerance to high-fiber diets in pigs. In this study, 28 Meishan (MS) and 28 Large White (LW) pigs were subjected to feeding experiments involving various fiber levels. Subsequently, multi-omics was employed to investigate the influence of host-microbiota interactions on the fiber degradation of pigs.

A subgroup of pigs from two experiments (EXP) were selected to evaluate the impact of pigs fed diets containing peroxidized soybean oil (SO) on plasma-based measures of oxidative stress and vitamin E. Pigs were fed diets containing SO that was either unprocessed (23 °C; peroxide value of 3 meq/kg and an anisidine value of 4) or thermally processed at 135 °C for 42 h (peroxide value of 30 meq/kg and an anisidine value of 501). The corn-soybean meal-based diets contained either 10% SO (EXP 1) or 8% SO (EXP 2).

Article Synopsis
- Feeding pigs lipids with high levels of lipid oxidation products (LOP) negatively impacts their growth performance, but the specific quantitative relationship between LOP and pig growth metrics like growth rate and feed efficiency has not been fully established.
- Four experiments were conducted using varying sources of lipids, such as soybean oil, choice white grease, and palm oil, with specific percentages included in pig diets to evaluate how different levels of LOP affected pig performance.
- The results showed significant statistical relationships between dietary lipid oxidation levels (measured by peroxide and anisidine values) and key performance indicators like average daily gain (ADG) and feed intake (ADFI), which can help predict how oxidized lipids in feed affect pig
A Guinea Pig Model of Pediatric Metabolic Dysfunction-Associated Steatohepatitis: Poor Vitamin C Status May Advance Disease.

Children and teenagers display a distinct metabolic dysfunction-associated steatohepatitis (MASH) phenotype, yet studies of childhood MASH are scarce and validated animal models lacking, limiting the development of treatments. Poor vitamin C (VitC) status may affect MASH progression and often co-occurs with high-fat diets and related metabolic imbalances. As a regulator of DNA methylation, poor VitC status may further contribute to MASH by regulating gene expression This study investigated guinea pigs-a species that, like humans, depends on vitC in the diet-as a model of pediatric MASH, examining the effects of poor VitC status on MASH hallmarks and global DNA methylation levels.
