EFFECT
OF
AUROFAC
[Vol. XXVII, Part IV
The 'high-protein' ration gave a highly significant increase in growth to six
weeks of age and a significant increase to seven weeks of age over the 'normal-
protein' ration.
Aurofac added to the 'normal-protein' ration gave a highly significant increase in
growth to six weeks and a significant increase to seven weeks over the same ration
without Aurofac.
Aurofac added to the 'high-protein' ration gave a highly significant increase in
growth to four weeks over the same ration without Aurofac. Addition of Aurofac to
the 'high-protein' ration gave no significant difference in growth to six and seven
weeks of age.
In a Trial No. 2 with 40 White Leghorn chicks on the 'normal-protein' ration and
40 on the 'high-protein' ration both containing Aurofac, there was a highly significant
difference in growth to six weeks in favour of the high-protein ration
There was no significant difference in feed efficiency or in mortality rate.
On the basis of two trials with Rhode Island Red and White Leghorn chicks a
'high-protein' ration containing a higher than normal amount of groundnut cake and
less maize gave significantly higher growth rates than a commonly recommended
'normal-protein' ration. Addition of Aurofac to 'normal' and 'high-protein' rations
gave an increased growth stimulation. With the 'high-protein' ration costing less
than the 'normal-protein' one, it was more economical to feed the 'high-protein'
ration.
