Özet
Bu araştırmada farklı enerji içerikli rasyonlarla yapılan zorlamalı beslemenin yerli kazlarda besi performans›, yağlı karaciğer üretimi ve bazı kan parametreleri üzerine etkileri araştırıldı. Araştırmanın farklı dönemlerinde alınan kan numunelerinde plazma lipidlerinden kolesterol, trigliserid, HDL, LDL ile karaciğer enzimlerinden SGOT, SGPT ve ALP seviyeleri saptandı. Buna göre deneme başında kontrol, I ve II. deneme gruplarında sırasıyla 245.42 ± 16.79, 370.14 ± 31.42; 233.85 ± 8.54, 374.85 ± 37.98 ve 236.78 ± 13.69, 372.40 ± 33.53 mg/dl olan kolesterol ve trigliserid miktarları deneme sonunda sırasıyla 262.85 ± 16.13, 373.00 ± 30.22; 592.57 ± 106.78, 2064.71 ± 300.65 ve 956.50 ± 146.13, 3831.50 ± 250.49 mg/dl miktarına yükseldi (P<0.001). Enzim seviyeleri karaciğer doku harabiyetine bağlı olarak arttı. Buna göre SGOT, SGPT ve ALP seviyeleri kontrol grubunda değişmezken I. deneme grubunda başlangıç değerlerinin sırasıyla 7.7, 3.6 ve 4.6 katına, II. deneme grubunda ise; 9.7, 5.6 ve 4.9 katına çıktı. Karaciğer numunelerinin yağ asitleri kompozisyonu laurik, miristik, stearik, palmitik, oleik, linoleik ve arahidonik asitler yönünden incelendiğinde deneme grupları kontrol grubundan istatistik olarak farklı bulundu (P<0.001). Kontrol grubunda karaciğer dokularının kuru madde, ham protein, ham yağ ve ham kül miktarları sırasıyla %30.74 ± 0.384, 17.22 ± 1.117, 7.11 ± 0.383 ve 1.24 ± 0.032 iken, I ve II. deneme gruplarında sırasıyla %38.59 ± 1.378, 13.40 ± 0.387, 27.75 ± 2.318, 0.85 ± 0.099 ve 44.65 ± 0.408, 11.25 ± 0.306, 42.39 ± 1.508, 0.81 ± 0.038 olarak saptandı (P<0.001). Karaciğer dokusunun artan yağ miktarıyla orantılı olarak deneme gruplarına ait karaciğer numunelerinde ham protein ve ham kül miktarı azalırken kuru madde miktarının arttığı tespit edildi. Araştırma sonunda kontrol grubunda ortalama 60.50 ± 2.16 g olarak tespit edilen karaciğer ağırlığı I ve II. deneme gruplarında sırasıyla 121.66 ± 10.15 ve 170.41 ± 15.94 g olarak elde edildi. Sonuç olarak yerli kazlarımızın yaşlı karaciğer üretimine elverişli olmadığı kanısına varıldı.
This study was carried out to determine the effect of force feeding on the fattening performance, fatty liver production and some blood parameters of adult geese. The level of cholesterol, triglyceride, HDL and LDL in plasma lipids and the hepatic enzymes SGOT, SGPT and ALP were analysed during different periods of the study. While the initial plasma lipid fractions, cholesterol, triglyceride, HDL and LDL, of the control group, group I and group II were 245.42 ± 16.79, 370.14 ± 31.42, 61.42 ± 6.37 and 11.90 ± 1.90; 233.85 ± 8.54, 374.85 ± 37.98, 61.57 ± 4.38 and 10.42 ± 2.22; and 236.78 ± 13.69, 372.40 ± 33.53, 61.37 ± 4.93 and 11.00 ± 1.66 mg/dl, they had increased 262.85 ± 16.13, 373.00 ± 30.22, 55.42 ± 7.98 and 10.85 ± 2.15; 592.57 ± 106.78, 2064.71 ± 300.65, 180.42 ± 10.80 and 90.57 ± 10.61; and 956.50 ± 146.13, 3831.50 ± 250.49, 247.50 ± 18.25 and 177.00 ± 21.09 mg/dl by the end of the cramming period (P < 0.001). Increased enzyme levels of SGOT, SGPT and ALP were accompanied by hepatic tissue destruction. Enzyme levels of SGOT, SGPT and ALP were approximately 7.7, 3.6, 4.6 and 9.7, 5.6, 4.9 fold higher in groups I and II, respectively, than in the control group. Lauric, myristic, stearic, palmitic, oleic, lynoleic and arachidonic acid contents of liver samples of both groups of force-fed birds were statistically significant compared with the control group (P < 0.001). Dry matter, crude protein, ether extract and crude ash contents of liver samples were 30.74 ± 0.384, 17.22 ± 1.117, 7.11 ± 0.383 and 1.24 ± 0.032% in the control group whereas they were 38.59 ± 1.378, 13.40 ± 0.387, 27.75 ± 2.318 and 0.85 ± 0.099%; and 44.65 ± 0.408, 11.25 ± 0.306, 42.39 ± 1.508 and 0.81 ± 0.038% in groups I and II, respectively (P < 0.001). Although crude protein and crude ash content decreased, dry matter content increased along with by ether extract content in the liver samples of groups I and II. At slaughter, the average liver weight of the control group was 60.50 ± 2.16 g, whereas it was 121.66 ± 10.15 and 170.41 ± 15.94 g in groups I and II, respectively. In conclusion, Turkish geese are not suitable for fatty liver production.
