Omega-3 fatty acids as feed supplement modulates blood formation and body weight in Rattus norvegicus model
Abstract
Omega-3 fatty acids’ inclusion as feed supplement in the diets of both human and animals has been found to play a significant role in body metabolism. The aim of this present study was to evaluate the effects of graded doses of omega-3 fatty acids on haematology and body weight of adult male and female Rattus norvegicus (Wistar albino rats) as a model animal. A total of seventy-two adult male and female albino rats were randomly assigned into two experimental units. Each unit was grouped into three and received different treatment diets. Blood erythrocytes and weight were sampled on days 0, 14 and 28 to evaluate haematological parameters and body weight. Results showed concentration- and time-dependent significant increases (p 0.05) in the red blood cells (RBCs) and mean cell haemoglobin concentration (MCHC) in male rats after day 0. In female rats, significant increases (p 0.05) in both experimental units. Our findings depict that the use of omega-3 fatty acids in the diets of both male and female rats produced a dose-dependent effect on blood formation while its role in controlling weight gain was observed. Hence, its intake in both animal and human diets should be rightly prescribed.
How strong is the evidence?
Evidence Hub reads this as a randomized trial. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
