Effects of Corn Meals with Different Processing Methods on Digestion and Metabolism, Plasma Biochemical Indexes, Growth and Development of 6-Month-Old Yili Horses
摘要
Abstract
This experiment aimed to study the effects of corn meals with different processing methods on diges⁃tion and metabolism, plasma biochemical indexes, growth and development of 6⁃month⁃old Yili horses, and provided a reference for the application of steam⁃flaked corn meal and extruded corn meal in horses’ diets. Twenty healthy Yili male horses with the age of 6 months and the average body weight of (105.10±11.83) kg were randomly divided into 4 groups, and each group had 5 horses. Each horse was fed 0.3 kg powder concen⁃trated feed and 3.5 kg alfalfa hay per day. Besides, each of horse in control group, trial groupsⅠ,Ⅱ andⅢwas fed with 0.3 kg grinding corn meal, 0.3 kg grinding corn meal+1 g α⁃amylase, 0.3 kg steam⁃flaked corn meal, and 0.3 kg extruded corn meal, respectively. The digestion and metabolism experiment lasted for 20 d comprised a 13 d adaptation and 7 d trial period. The results showed that the digestion of dry matter ( DM) , organic material ( OM) , crude protein ( CP) , neutral detergent fiber ( NDF) and acid detergent fiber ( ADF) , and the digestibility of NDF and ADF in trial group Ⅲ were significantly higher than those in control group ( P<0.05) . The retention rates of nitrogen ( N) , calcium ( Ca) and phosphorus ( P) in trial group Ⅲ were significantly higher than those in control group and trial groupⅠ( P<0.05) . The metabolic energy ( ME) and digestible energy ( DE) in trial groupⅢwere significantly higher than those in control group and trial groupⅠ(P<0.05), while there were no significant differences among control group and trial groups Ⅰ, Ⅱ (P>0.05). The body weight gain (BWG) and average daily gain (ADG) in trial groupⅢwere higher than those in other groups, but the differences were not significant ( P>0.05) . In aspect of body slanting length increase, the trial groupⅢwas significantly higher than other groups ( P<0.05) . The chest measurement increase in trail group Ⅱ was significantly higher than that in other three groups (P<0.05), but there were no significant differences in plasma biochemical indexes among groups (P>0.05). Therefore, feeding extruded corn meal can improve the digestibility of dietary nutrients, increase the energy metabolism and promote the growth and development of 6⁃month⁃old Yili horses, but feeding grinding corn meal containing enzyme preparation or steam⁃flaked corn meal has no significant promoting effects on the nutrient digestibility and the growth and de⁃velopment of 6⁃month⁃old Yili horses.关键词
