ABSTRACT

Rye and rapeseed meal (RSM) are alternatives to wheat and soybean meal (SBM) in pig nutrition. The inclusion of rye and RSM instead of wheat and SBM may increase dietary fibre content in the feed, which may affect digestive physiology and intestinal function. However, research on the combined feeding of rye and RSM in piglets is still scarce. The aim of this study was to investigate the effects of rye and RSM containing feed on growth performance, protein and amino acid digestibility, physical characteristics of the digesta and the intestinal morphology in weaner piglets. A total of 88 piglets aged 28 d were randomly allotted to four different feeding groups at weaning: wheat/SBM, wheat/RSM, rye/SBM, rye/RSM. Cereals were included at 48%, SBM at 25% and RSM at 30%. Body weight gain and feed intake were recorded weekly. After 33 d, piglets were euthanised for assessment of digesta and intestinal morphology. Rye did not affect performance, whilst RSM resulted in reduced weight gain (p = 0.024) and feed intake (p = 0.037). Apparent ileal digestibility of crude protein and amino acids was decreased by rye and RSM (p < 0.05). Rye caused an acidification (p = 0.045) and increased viscosity (p = 0.013) of small intestinal digesta, a lower dry matter content of jejunal and colonic digesta (p < 0.05) and an increased relative weight of the colon tissue (p < 0.001). In conclusion, performance was not reduced when rye was used as an alternative to wheat in diets for weaner piglets. The inclusion of RSM instead of SBM to piglets’ diet lowered animal performance under our conditions. Further investigations are warranted to characterise the quality of rapeseed meal and the optimum inclusion level in the diet for young pigs.

谷物和蛋白质来源对断奶仔猪生产性能、表观回肠蛋白质消化率和肠道特性的影响

摘要

黑麦和菜籽粕 (RSM) 是猪营养中小麦和豆粕 (SBM) 的替代品。加入黑麦和 RSM 代替小麦和豆粕可能会增加饲料中的膳食纤维含量,这可能会影响消化生理和肠道功能。然而,对仔猪黑麦和RSM联合饲喂的研究仍然很少。本研究的目的是研究含有黑麦和 RSM 的饲料对断奶仔猪生长性能、蛋白质和氨基酸消化率、食糜物理特性和肠道形态的影响。断奶时将 88 头 28 日龄仔猪随机分配到 4 个不同的饲喂组:小麦/SBM、小麦/RSM、黑麦/SBM、黑麦/RSM。谷物占 48%,SBM 占 25%,RSM 占 30%。每周记录体重增加和采食量。33 d 后,对仔猪实施安乐死以评估食糜和肠道形态。黑麦不影响性能,而 RSM 导致体重增加减少(p = 0.024)和采食量(p = 0.037)。黑麦和RSM降低了粗蛋白和氨基酸的表观回肠消化率(p <  0.05)。黑麦导致小肠食糜酸化 ( p = 0.045) 和粘度增加 ( p = 0.013),空肠和结肠食糜干物质含量降低 ( p <  0.05) 和结肠组织的相对重量增加 ( p< 0.001)。总之,当断奶仔猪日粮中使用黑麦替代小麦时,生产性能并未降低。在我们的条件下,在仔猪日粮中加入 RSM 而不是 SBM 会降低动物的生产性能。需要进一步研究来表征菜籽粕的质量和幼猪日粮中的最佳添加水平。
