A total of 1,215 pigs (L337×1050, PIC, Hendersonville, TN) were used in a 156-d wean-to-finish experiment. Pigs were weaned at 21 d of age and placed in pens based on initial body weight (BW) with 27 pigs/pen. There were three dietary treatments including a: 1) control; 2) pigs fed diets containing AviPlus (micro-encapsulated sorbic and citric acids and synthetic thymol and vanillin botanicals; Vetagro Inc., Chicago, IL) during the nursery and finisher phases; or 3) pigs fed AviPlus during the nursery but not the finishing phase. AviPlus was included at 2.72 kg/ton from d 0 to 21, 0.90 kg/ton from d 21 to 42, and 0.45 kg/ton from d 42 to 156. Thus, there were 15 control pens and 30 Aviplus pens in the nursery and 15 pens for the 3 treatments in the finisher phase. On d 42, pigs were transported as intact pens to the finishing facility. Data were analyzed as a RCBD with pen as experimental unit. For the overall nursery period (d 0 to 42), pigs fed AviPlus had improved (P < 0.05) G:F, with no evidence of difference (P > 0.05) for d 42 BW, ADG, or ADFI. For the overall finishing period (d 42 to 156) and overall experimental period (d 0 to 156), there was no evidence of difference (P > 0.05) for BW, ADG, ADFI, or G:F. There was no evidence of difference (P > 0.05) observed for mortality and removals during the nursery, finisher, or overall. In summary, providing AviPlus during the nursery improved nursery G:F, but there was no effect on overall wean-to-finish performance.

184 Aviplus对育肥猪生长性能的评价

总共 1,215 头猪 (L337×1050, PIC, Hendersonville, TN) 用于 156 天的断奶至育成实验。猪在 21 日龄断奶,并根据初始体重 (BW) 放入猪栏,每栏 27 头猪。有三种饮食治疗,包括:a:1)对照;2) 猪在保育期和育肥期饲喂含有 AviPlus(微胶囊化山梨酸和柠檬酸以及合成百里酚和香草醛植物药;Vetagro Inc.,Chicago,IL)的日粮;或 3) 在保育期而不是育肥期喂食 AviPlus 的猪。AviPlus 在 0 至 21 天的 2.72 公斤/吨、21 至 42 天的 0.90 公斤/吨和 42 至 156 天的 0.45 公斤/吨。因此,在保育舍中有 15 个对照栏和 30 个 Aviplus 栏,并且完成阶段的 3 次处理 15 笔。在第 42 天,猪作为完整的围栏被运送到育肥设施。数据被分析为 RCBD,以笔为实验单位。在整个保育期(0 至 42 天),饲喂 AviPlus 的猪的 G:F 有所改善(P < 0.05),没有证据表明 42 天 BW、ADG 或 ADFI 存在差异(P > 0.05)。对于整个完成期(d 42 到 156)和整个实验期(d 0 到 156),没有证据表明 BW、ADG、ADFI 或 G:F 存在差异(P > 0.05)。没有证据表明在保育期、育成期或整体期间的死亡率和清除率存在差异 (P > 0.05)。总之,在保育期提供 AviPlus 提高保育期 G:F,但对断奶到育成的整体表现没有影响。0.05) d 42 BW、ADG 或 ADFI。对于整个完成期(d 42 到 156)和整个实验期(d 0 到 156),没有证据表明 BW、ADG、ADFI 或 G:F 存在差异(P > 0.05)。没有证据表明在保育期、育成期或整体期间的死亡率和清除率存在差异 (P > 0.05)。总之,在保育期提供 AviPlus 提高保育期 G:F,但对断奶到育成的整体表现没有影响。0.05) d 42 BW、ADG 或 ADFI。对于整个完成期(d 42 到 156)和整个实验期(d 0 到 156),没有证据表明 BW、ADG、ADFI 或 G:F 存在差异(P > 0.05)。没有证据表明在保育期、育成期或整体期间的死亡率和清除率存在差异 (P > 0.05)。总之,在保育期提供 AviPlus 提高保育期 G:F,但对断奶到育成的整体表现没有影响。
