摘要

为确定妊娠前期和中期云南半细毛羊的钙需要量，选用体况良好、年龄一致、体重（45.14±3.94）kg、配种日期一致的经产2胎妊娠期云南半细毛羊50只，随机分成5个组（每组10只），分别饲喂钙水平为0.42%、0.45%、0.56%、0.65%和0.82%的试验饲粮。从妊娠第46天算起，试验期共74 d，其中预试期14 d，正试期60 d。在妊娠前期（妊娠第70~75天）和中期（妊娠第100~105天）分别从各组中选择5只羊进行为期5 d的消化代谢试验。结果表明：1）饲粮钙水平对妊娠前期和中期云南半细毛羊的干物质采食量、总增重、平均日增重及料重比均无显著影响（P>0.05）。2）随饲粮钙水平的升高，妊娠前期和中期云南半细毛羊进食钙和排泄钙显著增加（P<0.05）。钙表观消化率在妊娠前期表现为0.82%组显著高于0.45%、0.56%组（P<0.05），在妊娠中期表现为0.82%组显著高于0.42%、0.45%、0.56%组（P<0.05），0.65%组显著高于0.42%、0.45%组（P<0.05）。妊娠前期0.82%组沉积钙显著高于其他组（P<0.05），0.65%组显著高于0.42%、0.45%、0.56%组（P<0.05），妊娠中期0.82%组沉积钙显著高于其他组（P<0.05），0.65%组显著高于0.42%、0.45%组（P<0.05）。在钙沉积率方面，妊娠前期0.82%组显著高于0.45%和0.56%组（P<0.05），妊娠中期0.82%组显著高于其他组各组（P<0.05），0.65%组显著高于0.42%、0.45%组（P<0.05）。综上可知，在本试验条件下，饲粮钙水平不影响妊娠前期和中期云南半细毛羊的生长性能，但显著影响钙的进食量、排泄量、沉积量、表观消化率及沉积率。妊娠前期和中期云南半细毛羊的钙维持需要量分别为0.108 7和0.131 0 g/（kg W0.75·d），钙总需要量分别为0.490、0.508 g/（kg W0.75·d）。

Abstract

This experiment was conducted to determine the calcium requirement of Yunnan semi-fine wool sheep in early and mid-pregnancy. Fifty multiparous Yunan semi-fine wool sheep with good body condition, similar age and breeding date, body weight of (45.14±3.94) kg, were selected and randomly allocated into 5 groups (10 sheep per group), and were fed experimental diets with the calcium level of 0.42%, 0.45%, 0.56%, 0.65% and 0.82%, respectively. The experiment began on the 46th day of pregnancy and lasted for 74 days, with 14-day preliminary period and 60-day formal period. In early (the 70th to 75th day of pregnancy) and mid-pregnancy (the 100th to 105th day of pregnancy), five sheep were selected from each group for a 5-d digestion and metabolism trial. The results showed as follows:1) dietary calcium level did not significantly affect the dry matter intake, total weight gain, average daily gain and feed/gain (P>0.05). 2) With the dietary calcium level increasing, the calcium intake and calcium excretion of Yunnan semi-fine wool sheep in early and mid-pregnancy were significantly increased (P<0.05). The apparent digestibility of calcium in early pregnancy showed that 0.82% group was significantly higher than 0.45% and 0.56% groups (P<0.05), and it in mid-pregnancy showed that 0.82% group was significantly higher than 0.42%, 0.45% and 0.56% groups (P<0.05), and 0.65% group was significantly higher than 0.42% and 0.45%groups (P<0.05). In early pregnancy, the calcium deposition in 0.82% was significantly higher than that in other groups (P<0.05), and it in 0.65% group was significantly higher than that in 0.42%, 0.45% and 0.56% groups (P<0.05); the calcium deposition rate in 0.82% group was significantly higher than that in 0.45% and 0.56% groups (P<0.05). In mid-pregnancy, the calcium deposition in 0.82% was significantly higher than that in other groups (P<0.05), and it in 0.65% group was significantly higher than that in 0.42% and 0.45% groups (P<0.05); the calcium deposition rate in 0.82% was significantly higher than that in other groups (P<0.05), and it in 0.65% group was significantly higher than that in 0.42% and 0.45% groups (P<0.05). In conclusion, under the condition of this experiment, dietary calcium level do not affect the growth performance, but significantly affects the intake, excretion, deposition, apparent digestibility and deposition rate of calcium of Yunnan semi-fine wool sheep in early and mid-pregnancy. The maintenance calcium requirement of Yunnan semi-fine wool sheep in early and mid-pregnancy is 0.108 7 and 0.131 0 g/(kg W0.75·d), and the total calcium requirement is 0.490 and 0.508 g/(kg W0.75·d), respectively.
