摘要

摘要本研究旨在评价绿色生物精炼厂青贮汁在猪液体日粮中的应用及其对猪生长、清洁和健康的影响。96头(L × Y) × H型有机饲养猪分别饲喂对照饲粮(c型饲粮)和青贮料汁饲粮(sfj型饲粮)。c型日粮是一种商品饲料，在饲喂前与水混合。SFJ型饲粮采用较低比例的商品饲料，以青贮饲料汁(SFJ)代替水，理论上可替代饲粮粗蛋白质含量的10%。所有猪都喝了这些汁液，生长情况相似，平均为0.48公斤/天。SFJ组猪背部和头部的清洁度显著高于C组(P < 0.001)，但直肠和猪圈的清洁度无显著差异。青贮汁对卫生措施的影响很小，可能是猪的潜在当地饲料成分。

Juice from silage in green bio refineries – a potential feed ingredient in liquid diets to weaned pigs

ABSTRACT The objective of this study was to evaluate silage juice from green bio refineries in liquid diets to pigs and its’ effect on growth, cleanliness and health. Ninety-six (L × Y) × H organically raised pigs were fed either a control diet (C-diet) or a silage feed juice diet (SFJ-diet). The C-diet consisted of a commercial feed mixed with water prior to feeding. The SFJ-diet consisted of a lower ration of commercial feed mixed with silage feed juice (SFJ) instead of water, theoretically replacing 10% of the dietary crude protein content. All pigs consumed the juice and grew similarly, on average 0.48 kg/day. SFJ pigs were significantly dirtier on their back and head than C pigs (P < 0.001 for all), but cleanliness in the rectum area and in the pen did not differ. Silage juice had only minor effects on hygienic measures and could be a potential local feed ingredient to pigs.
