Effect of Feeding Graded Levels of Poultry Slaughter Waste on Performance of Labrador Pups

Diets containing processed poultry slaughter waste (PSW) at 0, 10 and 20% levels in diets 1, 2 and 3, respectively were fed to the Labrador pups and during a 20 weeks long growth trial the ADG was 109.56±7.62, 122.95±3.39 and 124.46±4.49g for diet 1 (control), 2 and 3, respectively, and feed efficiency was similar on all diets. CP efficiency was 13.56% higher on diets 3 and 2 than on control. ME efficiency (kcal/g gain) of diets 3 (8.82±0.33) and 2 (8.92±0.27) was significantly (P<0.05) higher than control diet (10.64±0.73). The DMI/100 kg body weight was comparable among the diets. DM digestibility of diet 3 (68.33±0.85) was higher (P<0.05) than diet 1 (63.75±0.93). There was no significant difference among diets for the digestibility of OM, CP and NFE. The CF digestibility of diets 3 and 2 was significantly (P<0.05) higher than control diet. The EE digestibility of diet 3 was significantly higher than diets 1 and 2, while comparable between diets 1 and 2. PSW containing diets were economical and it could be included up to 20% level in dog diets.
