Abstract

An experimental feeding study was conducted to visualize the response of young growing puppies to two levels of fats and salmon oil using iso-nitrogenous equi-caloric diets. Twelve Labrador retriever puppies (6 females and 6males) with 60 days’ age and with an average LBW of 6.750 kg were assigned to two groups each of 6 puppies (3 females and 3 males) and housed in individual kennels. Two iso- nitrogenous iso-caloric diets of the same fiber content were prepared by mixing suitable amounts of two commercial dry food brands on the basis of their actual chemical composition. The first diet; high fat and salmon oil diet (HFS) contains 18.5% EE (including 3% salmon oil) and 41.5% NFE. Meanwhile, the second diet;low fat and salmon oil diet (LFS) contains 12% EE (including 0.6% salmon oil) and 48.5% NFE. The feeding trial lasted for 14 weeks. Results revealed that feeding young growing puppies on high levels of fats and salmon oil has a positive significant impact on growth performance parameters including interval and final body weight, body weight gain, actual food amounts and also significantly reduced total amounts of refusal food. In addition, HFS diet exhibited a marked significant increase in serum IGF-1 levels but not affected the serum insulin concentrations HFS diet resulted in a significant elevation of total Cholesterol and LDL levels. Meanwhile, HDL, VLDL and total triglycerides levels and fasting serum glucose were not affected. Finally, HFS diet increased both digestible nitrogen absorption and fat absorption percent.
