The aim of this study was to investigate the effect of two dietary treatments (liquid creep feed (LCF) and dry creep feed (DCF)) offered during the suckling period on feed disappearance, number of eaters, and intestinal enzymatic development at weaning in an on-farm study with 347 piglets. Piglets were allocated to either the DCF or LCF treatment from day 10 to day 24 postpartum for 9 h a day. Red ferric oxide (1%) was added to the diet to categorize piglets into eating categories (good eaters, moderate eaters, or non-eaters) via faecal swabs. At weaning, 40 piglets were sampled for intestinal enzymatic development. The LCF treatment increased the dry matter disappearance from day 10-18 ( < 0.001). The percentage of good eaters, moderate eaters and non-eaters did not differ between treatments ( > 0.05). The DCF pigs displayed greater average daily gain (ADG) pre-weaning ( = 0.024), and a greater body weight (BW) at day 61 ( < 0.001). The activity of lactase, maltase and sucrase in the proximal part of the small intestine were greatest ( < 0.001) in the DCF pigs.
本研究的目的是在一项针对347头仔猪的农场研究中，调查哺乳期提供的两种日粮处理方式（液体补饲（LCF）和干料补饲（DCF））对断奶时采食量、采食仔猪数量和肠道酶发育的影响。从产后第10天到第24天，仔猪每天接受9小时的DCF或LCF处理。在日粮中添加1%的红色氧化铁，通过粪便拭子将仔猪分为不同采食类别（采食良好、采食中等或不采食）。断奶时，对40头仔猪进行采样以研究肠道酶发育情况。LCF处理使第10 - 18天的干物质采食量增加（<0.001）。不同处理之间采食良好、采食中等和不采食仔猪的百分比没有差异（>0.05）。DCF组仔猪断奶前的平均日增重（ADG）更高（=0.024），并且在第61天体重（BW）更大（<0.001）。DCF组仔猪小肠近端乳糖酶、麦芽糖酶和蔗糖酶的活性最高（<0.001）。
