Abstract
An investigation was carried out with the objective to determine the
effect of chromium as chromium propionate on the growth of cross bred pigs
and to evaluate the economics of organic chromium supplementation in the
ration of cross bred pigs. Twenty four weaned piglets (12 male and 12 female)
with an average body weight of 18 kg were used as experimental animals. The
piglets were randomly divided into two groups with six replicates of two piglets
in each group and were randomly allotted to two dietary treatments T1 (control
diet) and T2 (control + 200 ppb chromium). The pigs were weighed at the
beginning of the experiment and later on at fortnightly intervals. Blood
samples were collected in the beginning and at the end of the experiment for the
analysis of various biochemical parameters. Digestion trial was conducted at
the end of the experiment to determine the digestibility coefficients of the
nutrients of the experimental diets.
Animals in the two dietary treatments showed similar (p>0.05) body
weight gain, average daily body weight gain and feed conversion efficiency.
There was a numerical increase in dry matter and crude protein digestibility of
Cr supplemented ration. There was no significant difference (p>0.05) between
the animals in the two groups for all the blood parameters studied except
phosphorus and cholesterol, which were significantly lower (p<0.05) for T2
group. There was non-significant decrease in triglycerides and increase in HDL
cholesterol level. The overall critical evaluation of the results obtained in the
present study indicate that though supplementation of chromium propionate did
not affect the growth or feed conversion efficiency of growing (Large White
Yorkshire X Desi) cross bred pigs, it can be beneficially used to improve the
lipid profile of the cross bred pigs.
