摘要
鲁梅克斯K-1试验日粮比对照日粮显著(p<0.05)、极显著(p<0.01)增加了奶牛头日乳产量(1.58千克)和标准乳产量(2.46千克),分别提高6.2%和10.5%;试验日粮乳脂率显著高于对照日粮(p<0.05);试验日粮头日乳脂量和乳干物质量极显著高于对照日粮(p<0.01),乳蛋白量和乳糖量显著高于对照日粮(p<0.05);经济效益分析表明投入利润比为1:4.14。
Supplement with Rumex K-1 forage significantly increased milk production(p<0.05)and Fat-corrected milk yield(p<0.01)by 1.58 kg/ d·cows、2.46kg/d·cows respectirely,enbanced by 6.2%、10.5% respectirely.Addition of Rumex K-1 forage to the diet increased the percentage of milk-fat (p<0.05),no differences were inarked for milk protein,milk lactose and milk dry matter percentages (p<0.05). Daily milk fat (p< 0.01)、milk protein(p<0.05)、milk lactose(p<0.05) and milk dry matter(p<0.01) were increased by Rumex K-1 forage diet.The ratio of input to net income was 1:4.14 by economic benefit analysis.
