Effects of steam-flaked corn on growth performance,slaughter performance,and meat quality of beef cattle
摘要
Abstract
In order to study the effects of steam-flaked corn on the growth performance,slaughter performance,and meat quality of beef cattle,40 Simmental crossbred beef cattle with a body weight of(224.05±14.56)kg were randomly divided into four groups with five replicates per group and two beef cattle per replicate.Crushed corn was added to the diet of the control group,and 33％,66％,and 100％steam-flaked corn were used to replace the crushed corn in test group Ⅰ～group Ⅲ,respectively.The pre-feeding period lasted for seven days,and the formal test period lasted for 120 days.The results showed that the final weight of the group Ⅱ and group Ⅲ increased by 6.27％(P＜0.05)and 10.64％(P＜0.01)compared to the control group,respectively.The total weight gain of the group Ⅰ～group Ⅲincreased by 7.56％(P＜0.05),21.29％(P＜0.01),and 33.45％(P＜0.01)compared to the control group,respectively.The live weight before slaughter of the group Ⅰ～group Ⅲ increased by 2.64％(P＜0.05),6.59％(P＜0.01),and 10.25％(P＜0.01)compared to the control group,respectively.The feed to gain ratio of the group Ⅱ and group Ⅲ was extremely lower than that of the control group(P＜0.01).The carcass weight and net meat weight of the group Ⅱ and group Ⅲwere extremely higher than those of the control group(P＜0.01).The content of crude protein in beef in the group Ⅱand group Ⅲ was extremely higher than that in the control group(P＜0.01).The crude fat content in the group Ⅲ was significantly higher than that in the control group(P＜0.05).The pH45min value and water loss rate of the group Ⅲ were significantly lower than those of the control group(P＜0.05).The aquaculture benefits of experimental group Ⅰ～group Ⅲ were increased by 15.36％,48.04％,and 77.98％compared to the control group,respectively.The study indicates that replacing common crushed corn with steam-flaked corn can improve the growth performance and slaughter performance of Simmental crossbred beef cattle,improve the quality of beef,and improve the economic benefit of beef cattle breeding.Replacing the common crushed corn with 100％steam-flaked corn in the diet has a better effect.关键词
