Abstract

This study was carried out to determine the effect of silage on fermentation quality. The silage was produced by forage yield of mixed planting of corn and soybeans which was planted as a second crop in Mardin ecological conditions. The field experiment was carried out in a Randomized Complete Experiment Design with three replications at 7 different planting ratios [corn (C), 70% corn + 30% soybean (70C30S), 60% corn + 40% soybean (60C40S), 50% corn + 50% soybean (50C50S), 40% corn +% 60 soybean (40C60S), 30% corn + 70% soybean (30C70S) and soybean (S)]. The single (pure) and mixed yield obtained from each plot were left to fermentation in glass jars for 90 days in four repetitions. According to the results of the study, the highest fresh biomass obtained was 71 071 and 68 333 kg ha-1 respectively from 60C40S and 70C30S mixtures, and the highest crude protein yield was obtained from 60C40S, 70C30S, 30C70S and 50C50S mixtures planting ratios. As the soybean ratio in the mixture increased, the CP ratio, silage pH and butyric acid (BA) concentration increased. While the lactic acid (LA) concentration of corn silage was the highest value with 2.67% in dry matter (DM), this value has been determined as 1.04% in soybean silage. To conclude, in regions having ecological conditions of Mardin province, it is recommended to mix planting with 30% or 40% ratio of soybean plant with corn plant to increase the protein value of corn silage and improve the fermentation of soybean.

Highlights

One of the crucial problems of animal breeding in Turkey is the inability to produce a sufficient amount of quality roughage
In the evaluation of the yield and quality of soybean and corn planted with different mixture ratios, it was found that the difference among plant height, green herbage yield, hay yield, crude protein (CP) ratio, and yield were significant (p
While CP varied between 7.93-13.05%, the highest CP according to the averages were found in single soybean planting with 13.05%, and the lowest CP was detected in single corn planting by 7.9%

Summary

Introduction

One of the crucial problems of animal breeding in Turkey is the inability to produce a sufficient amount of quality roughage. Natural meadows and pastures, which are one of the sources from which quality roughage is produced, have lost their yield power (yield capacity) due to the early and excessive grazing for many years. Roughages with a high-water ratio have a special effect on dairy cattle breeding enterprises. After harvesting, it all should be consumed in a short time. For this reason, in order to use the feed for a long time without spoiling, the feed must be either dried or ensiled. Said drying or ensiling is one of the commonly used storage forms for forages with high water content (Bilgen et al, 2005)
