Effect of replacement of de-hulled barley with water-soaked barley in corn?￠????soybean meal-based diet on growth performance, blood characteristics, and meat quality in finishing pigs

摘要

ABSTRACT A total of 144 crossbred pigs [(Yorkshire Landrace) ???? Duroc] with an average initial body weight (BW) of 61.7 kg were used to assess the effect of replacement of de-hulled barley (DB) with water soaked barley (WB) in corn-soybean meal-based diet on growth performance, blood characteristics, and meat quality in finishing pigs according to their BW and sex (12 replicates per treatment and 4 pigs per pen). The dietary treatments were: DB, basal diet containing 5% DB; WB1, basal diet + 5% WB (0?￠????8 weeks of feeding); WB2, basal diet + 5% WB (4?￠????8 weeks of feeding). At the end of week 4, the IgG concentration (p<.05) was higher in WB1 than DB and WB2. At the end of week 8, lymphocyte percent was higher (p<.05) in DB than WB1 whereas IgG concentration was higher in WB1 and WB2 than DB. The sensory evaluation of colour scored higher (p<.05) in WB1 and meat marbling scored higher (p<.05) in WB2 than in DB. A higher (p<.05) yellowness and drip loss (day 1 and day 5) was observed in DB than in WB1. In conclusion, replacement of DB with WB had a positive impact on blood characteristics and meat quality of finishing pigs.
