The Changes of Chemical Content of Natural Pastures with Different Using History during Growing Season

Abstract

This research was carried out on enclosured, grazed and abandoned pastures in Karahisarh village in the province of Tekirdag for two years (2010 and 2011). The measurements were taken on four line in each of four designated sampling areas on the pastures. The forage samples were taken between 30 March and 15 July for 15-days intervals. According to average of the two year, the ratio of crude protein, crude fat, crude ash content were found as 10.93%, 1.78% and 7.71% on enclosured pastures, 9.46%, 2.03% and 7.86% on grazed pastures and 8.55%, 1.69% and 8.55% on abandoned pastures, respectively. Between March and July, samples collected for 15-days intervals indicated that the highest ratio of crude protein was determined on 30 April on grazed pastures (10.86%), on 15 May on enclosured pastures (17.12%) and on 15 April on abandoned pastures (14.92%). ADF and NDF ratios which shows digestibility of feed were found in enclosured range as 38.28% and 49.68%, in the grazed range as 36.92% and 51.77%, on abandoned range as 35.84% and 50.93%, respectively.
