The Effect of Safflower on the In Vitro Digestion Parameters and Methane Production in Horse and Ruminant

The aim of this study was to determine the effects of using 5%, 10%, and 20% of safflower (Carthamus tinctorius L. Dinçer; without thorns) grain, and its hay and straw, on the in vitro fermentation parameters in the diets of horses and ruminants. The addition of up to 5% of crushed safflower grain to a horse’s diet had no negative effect on the in vitro total gas production, true dry matter digestion (T-DMD), metabolic energy (ME), gas yield at 24 h (GY24), partial factor (PF24), microbial crude protein production (MCP) and short chain fatty acid composition (SCFA) of digestion fluid; however, increasing the grain content negatively affected certain parameters (p0.05). Consequently, using up to 5% safflower grain, and 20% hay and straw has the potential as a feed source in the diets of horses and ruminants.
