Researches on increasing efficiency of natural and annual ranges in goat husbandary

In the study, forage were established with growing different forage crops annually and naturally range throught the year and efficiency of diffirent grazing systems on these were compared. The objectives of this study conducted on both animal and plant materials were to determine the effects of grazing systems on plant characteristics and yield and yield components of goat grazed on diffirent ranges. The study was carried out Tecnological and Agricultural Research Center of Çanakkale Onsekiz Mart University during 2009-2010. In grazing study, carried out four periods per year, triticale and sorghum-sudangrass hybrid were used as plant material for establishment of annual ranges. For grazing Turkish Saanen genotype was used as animal material.In spring grazings, the highest amont of grazed forage and gren herbage yield were obtained from three rotational grazing system for triticale ranges (P?0,05). Similarly the highest milk yield per goat was obtained from three rotational grazing system (P?0,05).Refreshment pruning in shrub ranges had a positive effect on species in shrub vegetation. In both experimental year of shrup species in the natural forage, pruned plots had a higher protein content comparing to natural plots. NDF, ADF, ADL and tanin contents in the natural range were higher than those in pruned plots (P?0,05). In the natural range the goats aditionally fed decreased milk yield in both plots.Sorghum-sudangrass hybrid annual range grazed during summer period. Green herbage yield and amounth of grazed herbage in the rotational systems produced higher results compared to free grazing system (P?0,05). The milk yield didn?t decrease in three rotational grazing system although it was end of the lactation period. Sorghum-sudangrass hybrid annual range provided gren herbage for four mounths.Triticale is and important fodder resourch. In autumn- spring range during fall season. In the range in wich autumn grazing was applied, grazing in the following spring in hibited suistainability of the range. It was observed that range vegetation was not able to regeneraited.
