| Abstract | The present study dealt with the technical and economic evaluations of broiler
formula feed produced in Anhui Province. The nutrient levels in the collected formulae
were checked. The nutrient contents in sampled raw materials and finished formula feed
mainly used in the Province were determined subjecting to chemical analysis. The data of
previous feeding trials were collected and analyzed. The results show the followings.
There was no significant difference in ME contents in the formulas used by big and
small feed mills and the feeding standard value ( P > 0.05 ). The CP and Met.+ Tyr.
contents in the formulas and finished feeds of big feed mills were significantly higher ( P
< 0.05 ) than those of small feed mills. However, there was no significant difference in the
other EAA contents and feeding standard values ( P > 0.05 ) except for the content of
Met.+ Tyr. The protein-energy ratio was not of the significant difference in all of the
checked feeds and feeding standard value ( P > 0.05 ). There was no significant difference
for the values of CF, EE, Ca, P, and Ca/P ratio between the feeds of big and small feed
mills and the value provided for by the feeding standard.
There was significant difference in the values of DWG, FCR, feed input, profit
based on the feeding trials by using the feeds made by big feed mills and by small feed
mills ( P < 0.05 ).
Optimum solution to feed formulation, least cost formula, was recommended. And
an application model of linear programming was developed to make raw material purchase
plan which is very important for a feed company to guarantee the quality of finished feeds. |
