DETERMINING THE EFFECTS OF WILTING TIME ON SOME QUALITY PARAMETERS IN SOYBEAN HAYLAGE

Abstract

This study was carried out in Adana province for two years (2016, 2017) to determine the effect of wilting times on soybean haylage. All of the harvests were made using the conditioner mower in the development phase of soybean R6. The harvested soybean forage was allowed to wilt for 4 different wilting times under field conditions. Small-scale haylage bales of 40-50 kg weight were prepared for each subject. These bales were wrapping with 4 layers of polyethylene material without any additives and storage to ferment for 60 days. The wilting time was based on crude protein, acid detergent fiber, neutral detergent fiber, digestible dry matter, dry matter consumption and relative feed value was found to have an effective statistical significance at 1% (p<0.01) significance level. Furthermore, it was determined that wilting time was effective at 1% (p <0.01) significance level on haylage bales weight, dry matter content, pH and haylage bales density. As a result, it was determined that the highest value in terms of relative feed value were obtained by wrapping the haylage after 18h - 22h of wilting. In addition, it was determined that in terms of crude protein, roughage quality was reduced by 31.4% on average with 80h wilting compared with the other applications.
