Farklı oranlarda pamuk tohumu içeren rasyonların süt ineklerinde bazı kan parametreleri üzerine etkileri

Bu çalışmada diyette farklı oranlarda bulunan pamuk tohumunun bazı kan parametreleri [hematokrit, hemoglobin, ortalama eritrosit hemoglobin konsantrasyonu (MCHC), eritrositlerin ozmotik frajilitesi] üzerine etkileri araştırılmıştır. Bu amaçla 4 Holştayn ırkı inek toplam 4 dönemden oluşan 4X4 Latin kare metoduna göre kullanılmıştır. Her dönem 14 gün adaptasyon ve 7 gün veri toplama süresinden oluştu. Bütün kan örnekleri sabah yemlemesinden ve sağımından sonra alındı. İneklerin diyetinde bulunan konsantre yemde pamuk tohumu oranları/sırasıyla %0 (Kontrol; C), % 12.5 (W-I), % 25 (W-II) ve % 37.5 (W-II1) pamuk tohumu olacak şekilde ayarlandı. Diyette bulunan pamuk tohumu sırasıyla 0 (C), 1 (W-I), 2 (W-II), 3 (W-III) kg/gün olarak hesaplandı. Yemde bulunan pamuk tohumunun % hematokrit (C=40.75 ± 1.55, W-1=41.00 ± 3.19, W-II=40.25 ± 5.03 ve W-III=43.25 ± 4.96), hemoglobin (C=10.93 ± 0.72, W-I=l 1.19 ± 1.01, W-II=10.26 ± 0.56, ve W-III=10.89 ± 0.31 g %) veya MCHC (C=267 ± 12, W-I=277 ± 30, W-II=270 ± 40 ve W-III=263 ± 35 g/L) seviyeleri üzerine herhangi bir etkisi gözlenmedi. Uygulamanın eritrositlerin ozmotik fragilitesi üzerine de herhangi bir etkisi bulunmadı. Sonuç olarak, yeme kısa süreli % 37.5'e varan oranlarda pamuk tohumu ilavesinin ineklerin kan parametreleri üzerine herhangi bir olumsuz etkisi gözlenmedi.

Effect of different levels of whole cottonseed in rations on some hematological parameters in dairy cattle

The effects of different levels of whole cottonseed (WCS) in the diet on hematological parameters (hematocrit %, hemoglobin, mean corpuscular hemoglobin concentration and osmotic fragility of erythrocytes) were examined in lactating cows. Four Holstein cows were assigned to a 4X4 Latin Square design with four stages. All stages had 14 d of adaptation and 7 d of data collection periods. All blood samples were collected from vena jugularis after morning feeding and milking. The dietary treatments included 0% (control; C), 12.5 % (W-I), 25 % (W-II) and 37.5 % (W-III) WCS of total concentrate in diet. Total WCS in the diet was calculated to be 0 (C), 1 (W-I), 2 (W-II), 3 (W-III) kg/d. No significant effects of WCSconcentration in diet fed were observed for mean % hematocrit (C=40.75 ± 1.55, W-I=41.00 ± 3.19, W-11=40.25 ± 5.03 and W-II1=43.25 ± 4.96), hemoglobin (C=10.93 ± 0.72, W-I=11.19 ± 1.01, W-II=10.26 ± 0.56, and W-III=10.89 ± 0.31 g %) or MCHC (C=267 ± 12, W-I=277 ± 30, W-II=270 ± 40 and W-II1=263 ± 35 g/L). Osmotic fragility of erythrocytes showed no treatment effect. In conclusion, short time feeding of up to 37.5% WCS had no negative effects on some blood parameters of animals.
