The current study compared the faecal microbiota composition of two pig breeds (autochthonous vs. commercial) to understand what happens after the integration of liquid whey in the diet and what the role of the host genetic is. The trial was conducted for 60 days, and the faecal microbiota composition was investigated at three time points, T0, T1 (after 30 days) and T2 (after 60 days) in 30 female pigs (20 commercial crossbred and 10 Nero Siciliano pigs). The animals were divided into four groups (two control and two treatment groups). Generally, in both breeds, (51%) and (36%) were the most abundant phylum whereas , and were the most abundant genera. The two breeds have a different reaction to a liquid whey diet. In fact, as shown by PERMANOVA analysis, the liquid whey significantly ( < 0.001) affects the microbiota composition of crossbreeds while not having an effect on the microbiota of the Nero Siciliano. Despite this, in both breeds and have been positively influenced by liquid whey and they promote intestinal health, improve immunity, increase performance, and feed efficiency. In conclusion, the integration of liquid whey had a different effect on the Nero Siciliano and crossbred pig breeds, emphasizing the importance of the host genetic profile in determining the faecal bacterial composition.
本研究比较了两个猪品种（本地品种与商业品种）的粪便微生物群组成，以了解日粮中添加液体乳清后会发生什么以及宿主基因的作用。试验持续60天，在30头母猪（20头商业杂交猪和10头西西里黑猪）的三个时间点T0、T1（30天后）和T2（60天后）对粪便微生物群组成进行了调查。动物被分为四组（两个对照组和两个处理组）。一般来说，在两个品种中，厚壁菌门（51%）和拟杆菌门（36%）是最丰富的门，而乳杆菌属、双歧杆菌属和肠球菌属是最丰富的属。两个品种对液体乳清日粮有不同反应。事实上，正如PERMANOVA分析所示，液体乳清显著（P<0.001）影响杂交猪的微生物群组成，而对西西里黑猪的微生物群没有影响。尽管如此，在两个品种中，乳杆菌属和双歧杆菌属都受到液体乳清的积极影响，它们促进肠道健康、提高免疫力、提高生产性能和饲料效率。总之，液体乳清的添加对西西里黑猪和杂交猪品种有不同影响，强调了宿主基因谱在决定粪便细菌组成中的重要性。
