Abstract
Two experiments were conducted to investigate the effect of feeding hog hair protein (HHP) on the nutritional value for poultry. In experiment 1, twenty roosters of Hanhyup-3 strain were alloted, and metabolizability of HHAA was measured. In experiment 2, forty roosters of Hanhyup-3 strain were alloted to 0, 3, 7.6 and 15.1% of HHAA treatments, 10 birds per treatment, and measured feed utilization and blood parameters. In experiment 1, no trend was found in excretion of amino acid, high in glysine and glutelin, low in valine, threonine, and methionine. HHAA metabolizability of serine, phenylalanine, alanine, and isoleucine was more higher than that of lysine, cystine, asparagine, and tyrosine. In experiment 2, as the HHAA level increased, feed intake decreased significantly in 15.1% treatment, but water intake increased significantly in 15.1% traetment. Dry matter and nitrogen metabolizability decreased in 7.6 and 15.1% treatments. Although no significant difference was found among three treatments(0, 3, and 5.7%), as the HHAA level increased, dry matter and nitrogen metabolizability decreased. Serum creatinine level was significantly increased in 15.1% treatment. In conclusion, it is considered that proper level to substitute soybean meal by HHAA was 10%.
