Puerperal hipokalsemili ineklerde kan kalsiyum düzeyleri ve klinik gözlemler

Çalışma, yaşları 3-10 arasında değişen toplam 60 inekde yapıldı. Hipokalsemi sendromu gösteren inek materyali: Semptomları belirgin şekilde grup A (n=20) ve hafif olarak gösteren inekler grup B (n=20) şeklinde ayrılırken, herhangi bir semptom göstermeyen 20 baş inek (grup C) kontrol grubu olarak çalışmaya alındı. Kan örnekleri hipokalsemi sendromu gösterenlerde (grup A ve B) i.v. kalsiyum sağaltımına başlanmadan hemen önce, kontrol grubunda (grup C) ise doğumdan hemen sonra vena jugularis'ten alındı. Çalışmada materyal olarak alınan tüm hayvanlarda, klinik olarak saptanan postpartum reprodüktif sorunlar da dikkate alındı. Kan kalsiyum düzeyleri şiddetli hipokalsemili hayvanlarda 5,50±0.33%mg, hafif hipokalsemililerde 7,42±0,06%mg olarak belirlendi. Şiddetli hipokalsemi semptomu gösterenlerde kan kalsiyum düzeyi hafif hipokalsemi semptomu gösterenlere göre önemli düzeyde düşük (p< 0,001) bulundu. Ancak, A ve B gruplarında kontrol grubundan (grup C; 9,10±0,16%mg) daha düşük bir Ca düzeyi (p

Blood calcium concentrations and clinical observationsin puerperal hypocalcemic cows.

The investigation was carried out on 60 cows, aged 3-10 years old. All cows were divided into three groups as strongly hypocalcemic cows (group A, n=20), slightly hypocalcemic cows (group B, n=20) and healty cows saved as control group (group C, n= 20). Blood samples were taken from jugular vein immediately before the start of the intravenous calcium treatment in group A and B and collected just after parturation in group C. Postpartum reproductive problems in all groups were also taken into consideration. The mean blood calcium concentration of the cows exhibiting strongly hypocalcemic signs (5.50 ±0.33 %mg) was significantly (p< 0,001) lower than that (7.42 ±0.06 % mg) of the cows had slightly hypocalcemic signs. However, the mean blood calcium concentrations of both groups (group A and B) was significantly (p < 0,001) lower than that (9.10 ±0.16 % mg) of control cows. Prolapsus uteri was observed in 4 cows (%20) in group A and in 1 cow (%5) in group B. Placental retention in group A and B was occured in 2 and 1 cow respectively. Prolapsus uteri and placental retention were not occured in control group. The numbers of cows which had been previously suffered parturient paresis, on th'e basis of their history, were 2 cows in group A and 3 cows in group B. As a result it is obtained that there are a relationship between the blood calcium concentrations and clinical signs of parturient paresis.
