【摘要】：本文通過對(duì)寧夏農(nóng)墾賀蘭山農(nóng)牧場(chǎng)飼養(yǎng)的烏拉圭奶牛、澳大利亞奶牛和寧夏本地奶牛三個(gè)荷斯坦奶牛群體頭胎牛的泌乳性能、繁殖性能的分析,探討三個(gè)荷斯坦奶牛群體在生產(chǎn)性能和選育水平的差異性。結(jié)果如下：1)同一牛場(chǎng),三個(gè)奶牛群體泌乳性能比較：日產(chǎn)奶量,本地牛顯著高于澳牛和烏牛(P0.05),澳牛和烏牛差異不顯著(P0.05)。乳脂率,本地牛澳牛烏牛,但差異均不顯著(P0.05)。乳蛋白率,烏牛澳牛本地牛,但差異均不顯著(P0.05)。305天產(chǎn)奶量,本地牛顯著高于烏牛(P0.05),本地牛與澳牛以及澳牛與烏牛差異均不顯著(P0.05)。泌乳持續(xù)力,泌乳前期0-70天,三個(gè)荷斯坦奶牛群體的泌乳持續(xù)力均高于理想值,但澳牛最為接近理想值；泌乳中期70-190天,烏牛和澳牛泌乳持續(xù)力波動(dòng)較大,偏離理想值,本地牛泌乳持續(xù)力波動(dòng)較小,趨近于理想值,說明烏牛和澳牛泌乳性能發(fā)揮沒有本地牛穩(wěn)定；泌乳后期190天以后,三個(gè)奶牛群體泌乳持續(xù)力基本都略高于理想值,說明后期三個(gè)奶牛群體泌乳性能發(fā)揮良好。體細(xì)胞數(shù),澳牛(24.518萬/mL)烏牛(24.022萬/mL)本地牛(22.615萬/mL),但差異不顯著(P0.05)。2)同一牛場(chǎng),三個(gè)奶牛群體繁殖性能比較：一次情期受胎率,澳牛(53.85%)烏牛(50.00%)本地牛(46.15%)。情期受胎率,烏牛(50.94%)澳牛(48.78%)本地牛(46.88%)。3)不同牛場(chǎng),三個(gè)奶牛群體泌乳性能比較：日產(chǎn)奶量,本地牛顯著高于澳牛和烏牛(P0.05),澳牛和烏牛差異不顯著(P0.05)。乳脂率,本地牛與澳牛以及澳牛與烏牛差異均不顯著(P0.05),而本地牛顯著高于烏牛(P0.05)。乳蛋白率,澳牛顯著高于烏牛和本地牛(P0.05),且烏牛也顯著高于本地牛(P0.05)。泌乳持續(xù)力,泌乳前期0-70天,三個(gè)荷斯坦奶牛群體的泌乳持續(xù)力均高于理想值,但澳牛最為接近理想值；泌乳中期70-190天,烏牛和澳牛泌乳持續(xù)力波動(dòng)較大,偏離理想值；本地牛泌乳持續(xù)力相對(duì)穩(wěn)定,趨近理想值；說明這一階段本地牛泌乳性能比烏牛和澳牛相對(duì)穩(wěn)定。4)不同牛場(chǎng),三個(gè)奶牛群體繁殖性能比較：一次情期受胎率,本地牛(49.47%)烏牛(46.44%)澳牛(32.39%),差異不顯著(P0.05)。情期受胎率,烏牛(54.71%)本地牛(51.27%)澳牛(49.38%),差異不顯著(P0.05)�？傮w來說,產(chǎn)奶量上本地牛優(yōu)于烏牛和澳牛；乳蛋白上,澳牛優(yōu)于烏牛和本地牛；在其它生產(chǎn)性能上,三個(gè)奶牛群體的沒有明顯差異。
[Abstract]:In this paper, the lactation and reproduction performance of the first born cows of three Holstein dairy cattle populations, namely, Uruguay cow, Australian cow and Ningxia native cow, which were raised in the farming farm of Helan Mountain in Ningxia, were analyzed. To explore the differences of production performance and breeding level among the three Holstein cows. The results were as follows: 1) the lactation performance of the three cows in the same farm: the daily milk yield of the local cattle was significantly higher than that of the Australian cattle and the black cow (P0.05), but the difference between the Australian cattle and the black cow was not significant (P0.05). Milk fat rate, local cattle, black cattle, but the difference was not significant (P0.05). The milk protein rate of local cattle was not significant (P0.05). The milk yield of local cattle was significantly higher than that of black cow (P0.05). There was no significant difference between local cattle and Australian cattle and black cow (P0.05). The lactation duration of the three Holstein cows was higher than the ideal value during 0-70 days of early lactation, but the Australian cow was the most close to the ideal value. In the middle period of 70 to 190 days, the lactation persistence of black and Australian cattle fluctuated greatly, deviating from the ideal value, and the fluctuation of local cow's lactation persistence was small and approaching to the ideal value, which indicated that the lactation performance of Wu Niu and Australian cattle was not stable as compared with that of local cattle. After 190 days of lactation, the lactation sustainability of the three groups was slightly higher than the ideal value, which indicated that the lactation performance of the three groups was good. The number of somatic cells in Australian cattle (245180 / mL), black cattle (240220 / mL), native cattle (226150 / mL), but the difference was not significant (P0.05). 2. The reproductive performance of three cows in the same farm was compared. Australian cattle (53.85%), black cattle (50.00%) and local cattle (46.15%). The rate of conception in oestrous period was 50.94%, 48.78% (48.78%) and 46.88%, respectively. 3) the lactation performance of three dairy cattle populations was compared with that of Australian cattle (48.78%), the daily milk yield of local cattle was significantly higher than that of Australian cattle and black cow (P0.05). There was no significant difference between Australian cattle and black cattle (P0.05). The milk fat rate of local cattle and Australian cattle as well as Australian cattle and black cattle were not significantly different (P0.05) but the local cattle were significantly higher than that of black cattle (P0.05). The milk protein rate of Australian cattle was significantly higher than that of black cattle and native cattle (P0.05), and the rate of milk protein was also significantly higher than that of native cattle (P0.05). The lactation duration of the three Holstein cows was higher than the ideal value during 0-70 days of early lactation, but the Australian cow was the most close to the ideal value. In the middle lactation period of 70-190 days, the lactation persistence of WuNiu and Australian cattle fluctuated greatly and deviated from the ideal value, and the lactation persistence of local cattle was relatively stable and approaching the ideal value. The results showed that the lactation performance of local cattle in this period was more stable than that of black cattle and Australian cattle. 4) the reproductive performance of the three populations in different cattle farms was compared with that in the first estrus period. Local cattle (49.47%), black cattle (46.44%) and Australian cattle (32.39%) had no significant difference (P0.05). The conception rate in oestrous period was 54.71% in black cattle, 51.27% in local cattle and 49.38% in Australian cattle, but the difference was not significant (P0.05). In general, the milk yield of native cattle is better than that of black cow and Australian cow; the milk protein of Australian cow is better than that of black cow and native cow.
