Effect of protected fat supplementation on some physiological changes of New Zealand White Rabbits
Abstract: A total of 30 mature New Zealand White doe rabbits (NZW) were used to study the effect of fat supplementation on some physiological parameters and production. Does were randomly divided into three diet treatment groups. The 1st group ( control) was offered the basal diet containing without fat supplementation, groups 2 and 3 were offered the basal diet supplemented by 2% and 4% protected fat (PF), respectively.
?Blood samples were taken from does and bunnies (6 weeks age).
The results showed that the does in- group I have the highest level of glucose. Addition of 4% PF was the highest levels of total protein, albumin and globulin. Level of cholesterol increased as the percentage of PF supplement increased. The highest concentration of T3 was found in does fed 4% PF followed by 2% and control. The highest level of calcium was found in does fed 2%PF. Sodium in serum of does decreased as the PF in the diet increased. While the level of potassium increased with the increase of PF. T3, glucose, chlesterol, calcium and potassium for bunnies was increased with the increased of PF and the highest levels of total protein albumin and globulin was found in bunnies fed 4 %PF.
Does fed diet supplemented with 2%PF had the best values of litter weight at weaning and feed intake decreased by around 11% from the case of control diet by either 2% or 4% fat supplement. Growth rate of bunnies fed 4% PF was higher by 10% and 20% than these fed 0% or 2% PF, respectively. Daily growth rates were 0.67,0.77 and 0.88% in control, 2% and 4% PF, respectively. The heaviest value for carcass weight was recorded with 2% followed by 4% PF and control group. Keywords: doe rabbits, protected fat, production, blood metabolites.
