摘要

本研究采取比较屠宰法测定20~35 kg杜泊羊×湖羊（杜湖） F1代公羔代常量元素[钙（Ca）、磷（P）、钾（K）、钠（Na）和镁（Mg）]的维持和生长需要量。选择35只杜湖F1代公羔[初体重为（19.20±0.36） kg]作为试验动物。随机选取7只羊，体重达约20 kg时进行屠宰以测定羊体常量元素含量的初始值。再随机选取7只羊，饲喂全混合颗粒饲粮，自由采食（AL），体重达约28 kg时进行屠宰。剩余的21只羊随机分为3个组，分别为AL组、70% AL组和40% AL组，每组7只羊。当AL组体重大约为35 kg时，这3组将被屠宰。屠宰后，测定空腹体（头+足、皮、内脏+血液和胴体）常量元素含量。结果表明：在20~35 kg体重阶段，杜湖F1代公羔的钙、磷、钾、钠和镁维持需要量[空腹体重（EBW）为基础]分别为24.01、11.70、3.20、6.60、1.20 mg/kg EBW，生长需要量[空腹体增重（EBWG）为基础]分别为11.55~11.41 g/kg EBWG、5.82~5.77 g/kg EBWG、1.47~1.69 g/kg EBWG、0.42~0.44 g/kg EBWG和0.98~0.88 g/kg EBWG。总之，20~35 kg杜湖F1代常量元素需要量的确定将有助于此生长阶段合理饲粮的配制，有利于羔羊生长性能的提高。

Abstract

A comparative slaughter trial was conducted to estimate the macroelement[calcium (Ca), phosphor (P), potassium (K), sodium (Na) and magnesium (Mg)] requirements for maintenance and growth of Dorper×Hu F1 male lambs weighted 20 to 35 kg. Thirty-five male lambs[initial body weight (BW) was (19.20±0.36) kg] were used as experimental animals. Seven lambs were randomly chosen and slaughtered at about 20 kg BW for measuring initial body macroelement contents. Another seven lambs were also randomly chosen and offered a pelleted mixed diet ad libitum (AL) and slaughtered at about 28 kg BW. The remaining 21 lambs were randomly allocated to 3 groups, which were AL, 70%AL and 40%AL groups, each group had 7 lambs. All lambs were slaughtered when lambs in AL group reached approximately 35 kg BW. Macroelement contents of empty body (head+feet, hide, internal organs+blood, and carcass) of lambs were determined. The results showed as follows:at 20 to 35 kg BW, Ca P, Na, K and Mg requirements for maintenance[based on empty body weight (EBW)] of Dorper×Hu F1 male lambs were 24.01, 11.70, 3.20, 6.60 and 1.20 mg/kg EBW, and those for growth[based on empty body weight gain (EBWG)] were 11.55 to 11.41 g/kg EBWG, 5.82 to 5.77 g/kg EBWG, 1.47 to 1.69 g/kg EBWG, 0.42 to 0.44 g/kg EBWG, and 0.98 to 0.88 g/kg EBWG. In conclusion, the determination of macroelement requirements may help to formulate more balanced diets for Dorper×Hu male lambs in the growth phase of 20 to 35 kg BW and improvement of growth performance of lambs.
