Abstract

Fasting pigs prior to harvest benefits food safety and pork quality. Studies have examined the effect of feed withdrawal prior to marketing applied on groups of pigs marketed at one time but not across multiple marketing events. Therefore, this study determined the effects of three feed withdrawal times before the first and final marketing event on pig performance, carcass traits, and economic return. A total of 695 finishing pigs (117.6 ± 1.06 kg) were allotted in a randomized complete block design and assigned to 1 of 3 treatments (24 pens per treatment; 9 to 10 pigs per pen). Treatments consisted of 12, 18, or 24 h (including transportation and lairage) of feed withdrawal prior to harvest to determine its effects on hot carcass weight (HCW), carcass yield, and economic costs vs. benefits of pigs marketed at two different marketing events (3 heaviest pigs per pen marketed 14-d prior to the final marketing of all remaining pigs). There were no differences in growth performance during the 14-d period between marketing events. However, pigs with 24 h of feed withdrawal prior to harvest had lower ( < 0.05) live BW at the first marketing event and at both events combined than pigs with 12 h of feed withdrawal. For carcass responses, pigs at the final marketing with 12 h of feed withdrawal prior to harvest had increased ( < 0.05) HCW compared to pigs with 24 h of feed withdrawal, leading to a tendency ( = 0.055) for increased HCW overall for the combined marketing events (0.5 kg heavier). When evaluating carcass yield using live weights at 24 h prior to harvest, pigs in the final marketing group with 12 h of feed withdrawal prior to harvest had greater yield ( < 0.05) than pigs marketed with 24 h of feed withdrawal; however, using live weights 12 h prior to harvest to calculate yield, pigs with 24 h of feed withdrawal prior to harvest had increased yield ( < 0.05) compared to pigs marketed with 12 h of feed withdrawal for both marketing events. There were no differences in backfat, loin depth, and percentage lean between treatments. Feed consumed and cost were reduced ( < 0.05) with 24 h treatment compared to 12 h in the overall period. In conclusion, withholding feed at the first marketing event did not impact pigs' growth performance or HCW. However, carcass yield was affected by the feed withdrawal time prior to harvest, with greater HCW for pigs with 12 h compared to 24 h of feed withdrawal at the final marketing event.

摘要

屠宰前禁食猪对食品安全和猪肉品质有益。已有研究考察了上市前停喂对一次性上市猪群的影响,但未涉及多个上市批次。因此,本研究确定了首次和末次上市前三种停喂时间对猪生长性能、胴体性状和经济效益的影响。总共695头育肥猪(117.6±1.06千克)按随机完全区组设计分配,分为3种处理中的1种(每种处理24个栏;每栏9至10头猪)。处理方式包括屠宰前停喂12、18或24小时(包括运输和圈养),以确定其对热胴体重(HCW)、胴体产量以及在两个不同上市批次上市猪的经济成本与效益的影响(每栏最重的3头猪在所有其余猪最终上市前14天上市)。两个上市批次之间的14天内生长性能无差异。然而,屠宰前停喂24小时的猪在首次上市时以及两次上市合计时的活体重均低于(<0.05)停喂12小时的猪。对于胴体反应,屠宰前停喂12小时的猪在最终上市时的HCW高于(<0.05)停喂24小时的猪,导致两次上市合计时HCW总体有增加趋势(P = 0.055)(重0.5千克)。在使用屠宰前24小时的活体重评估胴体产量时,最终上市组中屠宰前停喂12小时的猪的产量高于(<0.05)停喂24小时上市的猪;然而,在使用屠宰前12小时的活体重计算产量时,两个上市批次中屠宰前停喂24小时的猪的产量均高于(<0.05)停喂12小时上市的猪。各处理间背膘、腰厚和瘦肉率无差异。与12小时处理相比,24小时处理在整个期间的采食量和成本降低(<0.05)。总之,首次上市时停喂对猪的生长性能或HCW无影响。然而,屠宰前停喂时间影响胴体产量,在最终上市时,停喂12小时的猪比停喂24小时的猪HCW更高。
