In contrast, domestic pigs exhibited a decreased variety of these potentially health-enhancing bacteria, likely due to factors such as simplified diets and antibiotic use. Functional gene analysis revealed that pathways related to carbohydrate metabolism, lipid metabolism, immune response, and environmental adaptability were more enriched in wild boars.

Furthermore, it is crucial that the consequences for the health and welfare of horses and humans and the impact on the environment should also be considered. This review aimed to outline the advantages and disadvantages of different horse bedding types, focusing on their effects on the well-being of horses, humans, and the environment. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) technique was used as the methodology for this review. The search was performed in Scopus and Web of Science bibliometric databases and a total of 176 records were screened reading the title and the abstract. After screening, 58 records were retained and another 19 records were identified using their reference lists (i.e., snowballing). Therefore, a total of 77 records were considered. Straw and wood shavings were the most commonly used and studied bedding materials, while research on alternative options remains limited. Straw is identified as horses' preferred option, while shavings appear to be the easiest to clean, making them the preferred choice for stable workers. The parameters to consider when choosing the bedding most fit for purpose are many and their attributes differ across the various bedding types. This review has compared all the bedding types within the research literature to determine the best overall option using the research-based evidence. Each bedding type offers unique benefits and drawbacks summarised in a user-friendly table. Stable managers must consider and evaluate them to suit their specific needs, including the health and welfare of each horse and the husbandry system involved.

Therefore, poultry scientists are trying to adopt a new feeding strategy called AM/PM or split feeding to precisely meet hen's requirements more effectively than conventional methods. A 10-week cage layer trial was carried out via a Box-Behnken response surface design to identify the optimal amount of protein, energy, and calcium of the AM/PM diets. There were 13 test treatments with three levels of crude protein (19.6%/18.4%, 20.3%/17.7%, 21%/17%), calcium (3.3%/4.9%, 2.5%/5.7%, 1.6%/6.6%), and apparent metabolizable energy (AME) (12 MJ/kg/11.2 MJ/kg, 12.4 MJ/kg/10.8 MJ/kg, 12.8 MJ/kg/10.4 MJ/kg) for AM/PM diets respectively and a control treatment with industry baseline (CP-19%, Ca-4.1% and ME 11.6 MJ/kg). These are the calculated values of nutrients on a dry matter basis. A total of 364 hens were randomly distributed into 2 dietary treatments where each treatment had 13 replicates (2 hens per replicate cage, 26 hens per treatment). AM and PM diets were swapped out at approximately 8 am and 4 pm each day. Egg production and hen performance were measured daily and weekly, respectively, with egg quality, serum Ca, and nutrient digestibility measured at week 10. AM:PM intake and feed cost were calculated for each treatment. The optimal FCR, feed cost, and AM:PM intake were used to determine Ca, CP, and AME levels. The result showed that 6 out of 13 of our test treatments gave improved FCR compared to the control treatment (&lt;i&gt;p&lt;/i&gt; = 0.017). Dietary treatments did not affect overall hen weight and serum Ca and egg quality at week 10, except for the lower yolk color score in the control treatment (&lt;i&gt;p&lt;/i&gt; = 0.002). Hens in the experimental treatment, with calcium levels of 1.6% and 6.6%, crude protein (CP) levels of 19.6% and 18.4%, and AME content of 12.4 MJ/kg and 10.8 MJ/kg in the AM and PM diet, respectively, showed the highest apparent protein digestibility (56.6%) compared to the control group (&lt;i&gt;p&lt;/i&gt; &lt; 0.05). Similarly, hens receiving a treatment containing calcium at 3.3% and 4.9%, CP at 21% and 17%, and AME at 12.4 MJ/kg and 10.8 MJ/kg in the AM and PM diet, respectively, achieved the highest calcium digestibility (62.13%), while the control treatment yielded the lowest calcium digestibility (&lt;i&gt;p&lt;/i&gt; &lt; 0.05). After analyzing the data using the Box-Behnken response surface methodology, we found that (21/17)% CP, (3.3/4.9)% Ca, and (12/11.12) MJ/kg energy in the AM/PM diet gave the optimum performance in terms of lower feed cost and better feed efficiency. The data of AM:PM intake demonstrate that selective feeding occurs in between treatments (&lt;i&gt;p&lt;/i&gt; &lt; 0.001) and the degree of selection depends on the difference between the level of nutrients in AM and PM diet.

The heterogeneity of these cells poses a challenge for analyzing different cell types at different developmental stages. To characterize the transcriptomic landscape of porcine spermatogenesis and identify potential marker genes for spermatogonia, an unbiased transcriptomic study of spermatogenesis in neonatal and sexually mature six-month-old Meihua pigs was performed using 10× Genomics single-cell RNA sequencing (scRNA-seq). Through the collection of scRNA-seq data from 13,839 cells from Meihua pig testes, three germ cells (spermatogonia, spermatocytes and spermatids) and eight somatic cells (Sertoli cells, Leydig cells, myoid/stromal cells, endothelial cells, T cells/macrophages and erythroblasts) were identified. Pseudo-timing analysis showed that myoid cells and stromal cells originated from common progenitors in Meihua pigs. Functional enrichment analysis revealed that the differentially expressed genes (DEGs) in testicular somatic cells were enriched in the pathways of Ribosome, Oxidative phosphorylation, Protein processing in endoplasmic reticulum, Retrograde endocannabinoid signaling, Cellular senescence and Insulin signaling. Meanwhile, in the three different germ cells, except for pathways which were the same as the first three pathways for somatic cells, DEGs were also enriched in the Spliceosome, Cell cycle, Autophagy and Mitophagy pathways. Furthermore, the candidate marker gene TKTL1 in spermatogonia was identified using immunohistochemistry and immunofluorescence.
