“…The ratio of non-fibrous carbohydrate (NFC) to neutral detergent fiber (NDF) in forage exerts a significant impact on animal growth [38,39]. As per the findings of Chen Qian et al [40], a higher NFC/NDF ratio demonstrates a more favorable influence on sheep weight, rumen fermentation, microbial community composition, and fermentation characteristics. As shown in Figure 9 and Table 2, the NFC/NDF ratios were 1.22, 1.29, 1.44, 1.23, and 1.31 for the AD group, HAD group, and HVCD groups with air-gap spacings of 7 cm, 8.5 cm, and 10 cm, respectively.…”

The high nutritional value of alfalfa hay makes it a widely utilized component in animal feed. However, the current prevalent drying methods for forage have a significantly detrimental impact on the quality of alfalfa during the drying process. This study investigates the effects of high-voltage corona discharge (HVCD) treatment on post-cut alfalfa. Gradient experiments are conducted by adjusting the air-gap spacing at a voltage of 25 kV. The results demonstrate that as the distance decreases, there is an observed increase in the drying rate, rehydration rate, and color intensity of the HVCD-treated material. HVCD treatment significantly enhances crude protein content, which increases with decreasing air-gap spacing. Meanwhile, it negatively affects lignin, neutral detergent fiber (NDF), and acid detergent fiber (ADF) levels. The relative forage quality (RFQ) of alfalfa reaches its peak at an air-gap spacing of 7 cm. The application of HVCD disrupts the fiber structure and induces significant electroporation effects in cells. Minimal changes in functional groups preserve nutrient integrity. Furthermore, HVCD exhibits lower energy consumption compared to hot air dryers. The HVCD treatment is a highly efficient and effective method, with a gradual improvement in alfalfa hay quality as the air-gap distance decreases.

The purpose of this study was to investigate the difference of intestinal barrier function between Tianhua mutton sheep and Gansu alpine fine wool sheep by HE staining, VFA assay and 16S full-length sequencing. The results showed as follows: 1) Compared with Gansu alpine fine wool sheep, Tianhua mutton sheep showed significantly higher villus height, significantly lighter crypt depth and significantly higher ratio of villus to crypt in duodenum and ileum (P-value < 0.05). 2) In both duodenum and jejunum, the contents of acetic acid and total acid were significantly higher in Tianhua mutton sheep than in Gansu alpine fine wool sheep (P-value < 0.05). 3) The overall comparison of the intestinal tract revealed that the Ace index of Tianhua mutton sheep was significantly higher than that of Alpine fine wool sheep (P-value < 0.05). The intestinal flora was able to separate significantly between the two breeds. LEfSe analysis found that Clostridia, Christensenellaceae-R-7-group-bacterium-AC2043 was the high abundance differential species in Tianhua mutton sheep. 4)The dominant flora of the two fine wool sheep were different in the five intestinal segments, but the content of beneficial bacteria of Tianhua mutton sheep was generally higher than that of Gansu alpine fine wool sheep. It can be seen that the intestinal barrier of Tianhua mutton sheep is better than that of Gansu alpine fine wool sheep, and Tianhua mutton sheep has a stronger adaptation to the living conditions of alpine pasture.
