Abstract
Bu çalışmada Merinos koyunu, Arap atı, Karacabey Esmer sığırı ve çeşitli kökenli broilerlerin kan plazmasında vitamin E yoğunluğunun mevsimsel değişiklikleri belirlenmiştir. Bu amaçla, cins ve yaş gruplarına ayrılmış 80 koyun ile 40 koç, 40 at, 41 Esmer dana ve 83 broilerden mevsimleri temsil eden: temmuz, ekim, ocak ve nisan aylarında kan örnekleri alınmıştır. Kan plazmasında vitamin E yoğunluğunun mevsimlere göre farkları koyun, at ve sığır grupları için (P< 0.01), koçlar için ise (P< 0.05) düzeyinde istatistik önemli bulunmuştur. Bu yoğunluğun koyun alt gruplarında, koçlardan daha yüksek olduğu saptanmıştır. Kan plazması α- tokoferol yoğunluğu koyun, at ve sığır gruplarında kışın en düşük bulunmuştur. İlkbaharda yükselmeye başlayan bu düzeyin temmuzda koyun ve atlarda en yüksek değere ulaştığı gözlenmiştir. Mevsimlere göre grupların kan plazmalarında α- tokoferol yoğunluğu (mg/100 ml) sırasıyla aşağıda sunulmuştur.

In this study; the seasonal variations of vitamin E concentration in blood plasma of Merino sheeps, Arabian horses, Karacabey Brown catties and different originated broilers were determined, Blood samples of 80 sheeps and 40 rams in sex and age subgroups, 40 horses, 41 Brown yearling catties and 83 broilers were received in July, October, January and April months presenting summer, autumn, winter and spring. The differences of vitamin E concentrations in plasma according to the seasons, were found statistically singnificant at the levels; (P< 0.01 ) for sheep, horse and cattle groups and (P< 0.05) for only rams. The concentration levels of sheep subgroups were observed higher than rams. The α- tocopherol concentration levels for sheep, horse and cattle groups were found lowest in winter. The increases observed in spring were highest in July for sheeps and horses. The averages on α- tocopherol concentration (mg/100 ml) in plasma groups, according to the seasons were submitted below, respectively.
