【摘要】：通過黑龍江省7個不同地區(qū)肉牛養(yǎng)殖場血液鈣(Ca)、磷(P)和鎂(Mg)濃度的檢測比較,來判斷這7個肉牛養(yǎng)殖場肉牛鈣磷代謝的情況,為肉牛養(yǎng)殖場預(yù)防鈣磷代謝障礙疾病提供理論依據(jù)。選擇黑龍江省大慶、雙鴨山、九三、牡丹江市7個不同地區(qū)不同飼養(yǎng)方式的肉牛養(yǎng)殖場作為調(diào)查點,分別記為A組(雙鴨山放牧加舍飼)、B組(雙鴨山全舍飼)、C組(大慶全舍飼)、D組(九三放牧)、E組(大慶放牧加舍飼)、F組(大慶放牧加舍飼)、G組(牡丹江全舍飼),并對7個不同地區(qū)養(yǎng)殖場血中Ca、Mg和P的濃度及游離脂肪酸(NEFA)、葡萄糖(GLU)、β-羥丁酸(BHBA)進行比較分析,綜合判定7個肉牛養(yǎng)殖場Ca、P代謝的狀況。結(jié)果顯示:7個調(diào)查點65頭肉牛血漿中Ca、P和Mg濃度均在正常范圍內(nèi),各地區(qū)間血Ca濃度差異不顯著,P濃度有差異性,其中C、G組極顯著高于A組(P0.01);C、G組極顯著高于B組(P0.01);C組極顯著高于D、E、F組(P0.01);G組極顯著高于D組(P0.01);G組極顯著高于E組(P0.01);G組極顯著高于F組(P0.01),能量指標NEFA B組顯著高于D組(P0.05),其他各組間無差異性。GLU各組間存在差異其中A組顯著高于E組(P0.05);B組顯著高于A、D組(P0.05),極顯著高于E、F、G組(P0.01);C組極顯著高于A、D、E、F、G組(P0.01);D組顯著高于E組(P0.05);F組顯著高于E組(P0.05),BHBA有組間差異,C、D、E組極顯著高于A組(P0.01)、F組顯著高于A組(P0.05);C組顯著高于B組(P0.05);D、E組極顯著高于B組(P0.01);C組極顯著高于G組(P0.01);D組極顯著高于F、G組(P0.01);E組極顯著高于F、G組(P0.01)。各組間在血磷、NEFA、GLU、BHBA方面存在差異,與各組間的飼養(yǎng)方式,飼料精粗比及飼養(yǎng)環(huán)境有關(guān)。結(jié)果表明,黑龍江省大慶、雙鴨山、九三、牡丹江市7個不同地區(qū)肉牛養(yǎng)殖場沒有發(fā)生鈣磷代謝障礙性疾病,但也要預(yù)防營養(yǎng)代謝疾病的發(fā)生。
[Abstract]:The calcium and phosphorus metabolism of beef cattle in 7 beef farms in Heilongjiang Province were determined by comparing the concentrations of calcium, calcium, phosphorus (P) and magnesium (mg) in the blood of 7 beef cattle farms in Heilongjiang Province. To provide theoretical basis for the prevention of calcium and phosphorus metabolic disorders in beef cattle farms, 7 beef cattle farms with different feeding styles in Daqing, Shuangyashan, 93 and Mudanjiang were selected as investigation points. Group A (Shuangyashan grazing + feeding group B) (Shuangyashan Group) (Group C) (Group D of Daqing Group) (Group 93) (Group D of Daqing grazing + Group F) (Group D of Daqing grazing + Group G (Group G of Mudanjiang complete feeding), Group B (Group B) were recorded as Group A (Group A), Group A (Group B), Group A (Group B): Shuangyashan Group + Group B (Group B). The concentrations of Ca, mg and P in blood and free fatty acid (NEFAA), glucose gluconium (GLU), 尾 -hydroxybutyrate (尾 -hydroxybutyrate) in blood of 7 farms in 7 different areas were compared and analyzed. The results showed that the concentrations of CaOP and mg in plasma of 65 beef cattle in 7 survey points were within normal range, and there was no significant difference in plasma Ca concentration among different regions. Among them, the CU G group was significantly higher than the A group P0.01P0.01C group was significantly higher than B group P0.01C group was extremely significant higher than the D group P0.01P0.01G group extremely significant higher than the E group P0.01G group was extremely significant higher than the F group P0.01G group, the energy index NEFA B group was significantly higher than the D group P0.01G group was significantly higher than the D group P0.01G group, the energy index NEFA B group was significantly higher than the D group P0.01G group was higher than the D group P0.01G group was significantly higher than the D group P0.01G group. There was no difference among other groups. GLU was significantly higher in group A than that in group E, P0.05A was significantly higher than that in group A, and was significantly higher than that in group A and group A, and extremely significantly higher than that in group P0.01FG, group C, and in group C, significantly higher than that in group E, P0.05BHBA, and in group D, significantly higher than that in group E, P0.05BHBA. The difference between the two groups was significantly higher in group C than in group A (P 0.01), group C was significantly higher than that in group B (P 0.05), and that in group C was significantly higher than that in group B (P 0.01), group C was significantly higher than that in group G (P 0.01D), and that in group F was significantly higher than that in group A (P 0.01). There were differences in BHBA in blood of NEFAA and GLUUBBA. The results showed that there were no calcium and phosphorus metabolic disorders in 7 beef farms in Daqing, Shuangyashan, 93 and Mudanjiang in Heilongjiang Province. But also to prevent the occurrence of nutritional metabolic diseases.
