A study was conducted to investigate the impact of degraded date pits (DDP) on the development and morphology of the intestine in broilers. was used to produce the DDP using a solid-state degradation method. One hundred and eighty broilers were divided into six treatments in triplicate groups of 10 chicks each. The dietary treatments were: positive control with corn-soy basal diet, negative control with corn-soy basal diet + 20% oxytetracycline at 0.05%, corn-soy basal diet + 10% DDP, corn-soy basal diet + 0.2% mannan-oligosaccharides (MOS), corn-soy basal diet + 0.2% mannose and corn-soy basal diet + 0.1% mannose for 6 weeks. The results indicate that a 10% DDP diet increased the activities of the pancreatic enzymes, the villus length, and the villus/crypt ratio, and decreased the crypt depth of the intestine. In conclusion, when compared to oxytetracycline and MOS, DDP can be used as a replacement for antibiotic growth promoters for broilers while improving gut development and intestinal health.
进行了一项研究,以调查降解枣核(DDP)对肉鸡肠道发育和形态的影响。采用固态降解法制备DDP。180只肉鸡被分为6个处理组,每组10只雏鸡,重复3次。日粮处理如下:以玉米-豆粕基础日粮为阳性对照,以玉米-豆粕基础日粮+0.05%的20%土霉素为阴性对照,玉米-豆粕基础日粮+10% DDP,玉米-豆粕基础日粮+0.2%甘露寡糖(MOS),玉米-豆粕基础日粮+0.2%甘露糖以及玉米-豆粕基础日粮+0.1%甘露糖,持续6周。结果表明,10% DDP日粮可提高胰腺酶活性、绒毛长度和绒毛/隐窝比值,并降低肠道隐窝深度。总之,与土霉素和MOS相比,DDP可作为肉鸡抗生素生长促进剂的替代品,同时改善肠道发育和肠道健康。
