“…This has driven the development of PGTFP in each region. Consistent with existing studies, PGTFP did not increase nationwide or in all regions over time (Zhong et al, 2022b). Rather, it mostly fluctuated in phases, especially over 2005-2021, which was affected by the spread of unexpected diseases such as swine flu, African swine fever, and COVID-19.…”

“…They found that the pig breeding industry shifted to the central region without a corresponding increase in efficiency. Zhong et al (2022b) analyzed the differences in green pig breeding between East and West China based on dominant pig breeding regions, revealing significantly higher PGTFP in the West than in the East and Central regions owing to the different transportation and environmental locations between these regions. Wang et al (2020) analyzed pig breeding efficiency between farms and emphasized the need to narrow the farm gap to improve efficiency.…”

Achieving green, healthy, and cyclical development in China’s pig industry not only enables the adjustment of the rural industrial structure but also helps meet community demand for safe meat, thus playing a critical role in promoting sustainable agricultural development. This research utilizes panel data from 21 provinces (districts) in China from 2004 to 2021 to construct an evaluation system for green total factor productivity in pig breeding (PGTFP). The super-efficient slacks-based measure (SBM) model is employed to measure PGTFP. Conversely, regional disparities in PGTFP are determined using the Dagum Gini coefficient method. Furthermore, we analyzed the convergence of pig breeding in different regions. The findings indicate that PGTFP in China exhibits fluctuations, with the highest PGTFP, observed in areas of constrained development. Development differences in PGTFP across China have gradually diminished, with the greatest development differences observed within potential growth areas. Furthermore, disparities between focused development areas and potential growth areas are the most pronounced and are primarily attributable to the super-variable density. Both α- and β-convergence are observed for PGTFP at the national level and within each breeding area. However, the α-convergence pattern during COVID-19 is not obvious. Consequently, the formulation of differentiated farming development strategies and fostering the coordinated development of pig breeding in all regions have become imperative. Meanwhile, preparing contingency prevention measures to promote stable and high-quality pig breeding is necessary.

“…On the contrary, large-scale farmers have advantages such as information and management [20], and their profitability [37] and risk management are sustainable. Therefore, large-scale farming contributes to stable hog production [20,38]. After the listing of hog futures, farmers can utilize hog futures to hedge their risks and promote the expansion of production scale.…”

China’s large-scale hog farmers are playing an increasingly important role in promoting the stable development of the hog industry. Taking large-scale hog enterprises as samples, based on hog sales data from January 2019 to July 2022, this paper adopts a two-way fixed-effects model to test the impact, mechanism, and heterogeneity of hog futures on the production stability of large-scale hog farmers. The study found that hog futures help promote stable production of large-scale farmers. This finding still holds after a series of robustness tests. The mechanism analysis found that, first, hog futures help large-scale farmers expand their risk management factor inputs. Second, hog futures help reduce the impact of hog price risk on production. Finally, hog futures help stabilize farmers’ production expectations. The moderating effects analysis found that the stabilizing effect of hog futures will enhance as farmers’ share of hog farming operations increases. Heterogeneity analysis found that when hog prices fluctuate negatively, hog futures help promote the stable production of large-scale farmers. When hog prices fluctuate positively, the production stabilization effect of hog futures is not obvious. Therefore, hog enterprises should be encouraged to participate in hog futures hedging transactions to promote stable hog production.

In this study, we investigated the effects of the dietary inclusion of different proportions of whole-plant corn silage on growth performance, serum biochemical indexes, and intestinal microorganisms in Hezuo pigs. Thirty-two two-month-old Hezuo pigs (body weight: 7.88 ± 0.81 kg) were randomly divided into four groups of eight pigs (half male, half female) each. The control (CON) group received a basal diet, while the three experimental groups were fed the basal diet, part of which had been replaced with 5%, 10%, and 15% whole-plant corn silage, respectively. The experiment lasted for 127 days, including 7 days of pre-testing and 120 days of formal testing. At the end of the experiment, blood and fecal samples were collected. Compared with the CON group, the feed-to-gain ratio was significantly lower in the 10% test group (p < 0.05), whereas the total protein, albumin, triglyceride, and glucose contents were significantly higher (p < 0.05). No significant differences in total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, creatinine, urea, aspartate aminotransferase, and alanine aminotransferase were observed among the groups (p > 0.05). The addition of whole-plant corn silage to the diet significantly increased alpha diversity in the pig gut based on 16S rRNA gene sequencing. The principal coordinate analysis results showed significant clustering of the different groups (p < 0.05). At the phylum level, the addition of whole-plant corn silage to the diet significantly decreased (p < 0.05) the relative abundance of Firmicutes and significantly increased (p < 0.05) that of Bacteroidetes. At the genus level, the relative abundance of Streptococcus significantly decreased (p < 0.05) with increasing silage supplementation levels, whereas species diversity significantly increased (p < 0.05). In conclusion, 10% is the recommended inclusion ratio for whole-plant corn silage in the diets of pigs.
