Abstract Field pea is an alternative starch and protein source for swine; however, feeding raw field pea to weaned pigs may reduce feed efficiency (G:F). Growth performance of weaned pigs fed field pea processed using treatments with heat and friction is unknown. To explore the effects of feed processing, field pea was ground (4.0-mm sieve), then either cold-pelleted (70–75 °C), steam-pelleted (80–85 °C) or extruded (115 °C) and then re-ground (3.2-mm sieve). Diets included 400 g per kg raw, cold-pelleted, steam-pelleted or extruded field pea replacing 300 g soybean meal (SBM) and 100 g wheat grain and were formulated to provide 10.0 MJ net energy (NE)/kg and 12.1 g standardised ileal digestible lysine/kg. In total, 236 pigs (weaned at 20 days of age) were housed in 60 pens in 4 rooms and fed 1 of 5 diets starting 2 weeks post-weaning [initial body weight (BW): 10 kg] for 3 weeks. The CATTD of gross energy and crude protein, digestible energy and predicted NE value were lower (P 0.05) by feeding or processing of field pea. To conclude, weaned pigs fed 400 g field pea/kg diet in substitution of SBM could maintain growth performance. Greater ADFI for field pea diets than SBM diet indicated that pigs compensated for the reduced energy value of field pea diets. Raw field pea can be included in late nursery diets without thermal treatment to replace 300 g SBM and 100 g wheat grain/kg diet.

饲喂生豌豆、冷颗粒、蒸汽颗粒或膨化豌豆的断奶猪的生长性能

摘要 豌豆是猪的替代淀粉和蛋白质来源;然而,给断奶猪喂生豌豆可能会降低饲料效率(G:F)。断奶猪饲喂使用加热和摩擦处理处理的豌豆的生长性能尚不清楚。为了探索饲料加工的影响,将豌豆磨碎(4.0 毫米筛),然后冷造粒 (70–75 °C)、蒸汽造粒 (80–85 °C) 或挤压 (115 °C) 和然后重新研磨(3.2 毫米筛)。日粮包括每公斤 400 克生的、冷造粒的、蒸汽造粒的或挤压的豌豆代替 300 克豆粕 (SBM) 和 100 克小麦籽粒,并配制成提供 10.0 MJ 净能量 (NE)/kg 和 12.1 g 标准化回肠可消化赖氨酸/kg。总共,236 头猪(在 20 日龄断奶)被圈在 4 个房间的 60 个猪圈中,并在断奶后 2 周 [初始体重 (BW):10 kg] 开始喂食 5 种日粮中的一种,持续 3 周。饲喂或加工豌豆的总能和粗蛋白、可消化能和预测NE值的CATTD较低(P<0.05)。总之,断奶仔猪饲喂 400 g 豌豆/kg 日粮代替 SBM 可以保持生长性能。豌豆日粮的 ADFI 大于 SBM 日粮表明猪补偿了豌豆日粮降低的能量值。未经热处理的后期育苗日粮中可以加入生豌豆,以代替 300 克 SBM 和 100 克小麦粒/公斤日粮。总之,断奶仔猪饲喂 400 g 豌豆/kg 日粮代替 SBM 可以保持生长性能。豌豆日粮的 ADFI 大于 SBM 日粮表明猪补偿了豌豆日粮降低的能量值。未经热处理的后期育苗日粮中可以加入生豌豆,以代替 300 克 SBM 和 100 克小麦粒/公斤日粮。总之,断奶仔猪饲喂 400 g 豌豆/kg 日粮代替 SBM 可以保持生长性能。豌豆日粮的 ADFI 大于 SBM 日粮表明猪补偿了豌豆日粮降低的能量值。未经热处理的后期育苗日粮中可以加入生豌豆,以代替 300 克 SBM 和 100 克小麦粒/公斤日粮。
