ABSTRACT

Asgharzadeh F, Behdani MA., Effect of nitrogen fertilizer and irrigation regime on In situ chemical composition and dry matter ruminal degradation of safflower (Carthamus tinctorius. L ) forage in fistulated cattle., Onl J Vet Res., 20(1):21-28, 2016. Effect of an irrigation regime and nitrogen fertilizer on the chemical composition (In situ), and dry matter digestibility of safflower plant (Carthamus tinctorius. L ) in fistulated cattle is reported. Safflower flowers were chopped to 3-5 cm particles. In situ treatments included unfertilized forage and Irrigation regime forage (controls), unfertilized and Irrigated forage, nitrogen fertilized (300 kg per ha) and Irrigation regime forage, nitrogen fertilized (300 kg per ha) and irrigated forage. Nitrogen fertilizer reduced neutral and acid detergent fiber but increased ash, Ca and P content of plant (P<0.05). Nitrogen fertilizer increased crude protein content of the plant (P<0.05). Nitrogen fertilization increased the a and c fractions and effective rumen degradability of dry matter (P<0.05).The findings suggest thatn nitrogen fertilization of the safflower plant may have improved its nutritional value.

Keywords: Ruminal degradability, Irrigation regime , Nitrogen fertilizer, Safflower plant.
