| Summary: | This research was analyzed the difference gross margin based on
the provide of feed with treatment control with using Zn organic and
measuring the gross margin highest in some treatment granting feed with
Zn organic. This research was started from November 2012 until February
2013. Two hundred eighty eight Japanese quail (Coturnix coturnix
japonica) were randomly plotted within four treatment by four replication
every treatment and consisted of eighteen bird each. The treatment were :
P0 (contain Zn organic premix with content of 0 %), P1 (Zn organic of 1
%), P2 (Zn organic of 3 %), and P3 (Zn organic of 5 %). The data obtained
were statistically analyzed by The One Way of ANOVA and next of
analyzed gross margin. The result of this research show that treatment
wasn�t effected to egg weight, result showed P0 11,65 g, P1 11,89 g, P2
11,92 g, dan P3 11,85 g. Treatment wasn�t effected to egg production
(%HDA) , the result were P0 84,80%, P1 82,26%, P2 80,24%, dan P3
85,00%. The treatment of Zn organic on premik increment variable costs
based on feeding, the result were P0 Rp 10344,66 /head/research period,
P1 Rp 10358,90 /head/research period, P2 Rp 10387,37 /head/research
period and P3 Rp 10415,82 /head/research period.The results showed
gross income of P0 Rp 59340 /head/research period, P1 Rp 57680
/head/research period, P2 Rp 55650 /head/research period, P3 Rp 59490
P3/head/research period. The results showed gross margin of P0 Rp
49120,34 /head/research period, P1 Rp 47446,10, /head/research period,
P2 Rp 45387,63 /head/research period, P3 Rp 49199,18 /head/research
period. The results showed that the use of Zn organic on premix with level
0%, 1%, 3%, and 5% had no effect against the real weight of the quail
egg. Gross margin was obtained at the treatment of organic Zn as much
as P3 (5%) of Rp 49199.18 per head per research period.
