Serum kalsiyum, magnezyum ve inorganik fosfor konsantrasyonları ile intraokuler basıncın atlarda yarış performansı üzerine etkisi

Öz

Bu çalışma, konkur atlarında göz içi basıncı ile serum Ca, Mg, ve Pi seviyelerinin yarış performansına etkilerini araştırmak amacıyla yapılmıştır. Bu amaçla Bişkek at spor okulunda aktif olarak yarışlara katılan 24 konkur atı seçildi. Çalışmada göz içi basınç (IOP) değerleri, her iki gözden de olacak şekilde tonometre kullanılarak yapıldı. Konkur atlarından kan örnekleri toplanarak serum Ca, Mg ve Pi seviyeleri ölçüldü. Çalışmada spor atlarının IOP, serum Ca, Mg ve Pi değerleri normal değer aralıklarında bulundu. Gruplar arası serum Ca ve P seviyeleri istatistiksel olarak farklı olmasına rağmen (p<0,05), IOP, serum Ca, Mg ve Pi seviyelerinin yarış performansını etkilemediği tespit edildi

The effect of intraocular pressure, serum calcium, magnesium and inorganic phosphorus concentrations on jumping performance of horses

Öz

The aim of the study is to evaluate the relation of serum mineral levels (Ca, Mg, P) with intraocular pressure (IOP) and jumping performance of horses. Twenty-four jumping horses, actively participated in the competition, were selected from a horse sport center in Bishkek and used for this study. Intraocular pressures in both eyes of each horse were measured by using a tonometer and blood samples were collected for analyzing serum Ca, P and Mg levels. IOP, Serum Ca, Mg and P values were measured in normal ranges in all jumping horses. Although Ca and P levels were found different in statistic (p<0,05) between the groups, IOP and serum mineral levels of Ca, Mg and P had not been found effective on race performance. IOP and serum Mg were not found effective on jumping performance of the horses. Similarly serum Ca, and P levels were not found effective on jumping performance, however Ca, and P levels were determined as different between the groups (p<0,05).
