An Investigation on the Effect of Adding Different Levels of Molasses on the Silage Quality of Pistachio (Pistachio vera) by Product and Wheat Straw Mixture Silages

The objective of this study was to investigate the effects of adding different levels of molasses (1-5%) on the silage quality, in vitro methane production and in vitro organic matter digestibility (IVOMD) of pistachio (Pistachio vera) by-product and wheat straw mixture silages. For this purpose, silages were prepared with pistachio by-product (85%) and wheat straw (15%) without molasses (control group), and with addition of molasses from 1% to 5% (treatment groups). All the treatments consisted of five replicate silos, and they were prepared in 1.5 L glass jar silos. While silage pH and acetic acid values decreased with addition of molasses levels (P
