Comparison of Growth Performance,Digestibility,and Serum Biochemical Indicators among Different Strains of Dezhou Donkeys During the Growth Period
摘要
Abstract
This study takes growing-period Dezhou donkeys of different strains as the research object,aiming to explore the differences in growth performance,digestibility,and serum biochemical indicators in order to provide data support for formulating their personalized feeding standards.The experiment selects 40 Dezhou donkey foals,and divides them into four treatment groups:Sanfen Male Donkeys,Sanfen Female Donkeys,Wutou Male Donkeys,and Wutou Female Donkeys.The trial includes a 30-day adaptation period and a 90-day formal trial period,during which the four treatment groups are fed the same kind of complete pelleted diet and allowed to feed freely.The results indicate that the Wutou male donkeys show significantly higher average daily gain and better feed-to-gain ratio compared to the Sanfen male donkeys(P<0.05),while for female donkeys of different strains,there are no significant differences in average daily feed intake,average daily gain,or feed-to-gain ratio(P>0.05).Regarding nutrient digestibility,Wutou male donkeys have significantly higher digestibility of organic matter,carbohydrates,and neutral detergent fiber than Sanfen male donkeys,whereas Wutou female donkeys have significantly lower digestibility of nitrogen-free extract than Sanfen female donkeys(P<0.05).In serum biochemical indicators,Wutou male donkeys exhibit significantly higher levels of uric acid and glucose,but lower levels of triglycerides than Sanfen male donkeys(P<0.05).For females,Wutou donkeys have significantly higher serum glucose levels,but lower levels of total protein and uric acid than Sanfen female donkeys(P<0.05).In summary,under the conditions of this trial,Wutou male donkeys demonstrate advantages over Sanfen male donkeys in terms of growth performance,nutrient utilization,and metabolism.However,no significant differences in growth performance are observed between different strains of female Dezhou donkeys.关键词
