(a) "Day old" broiler and breeder chicks are placed continually in 

 specified quantities throughout the area. 



(b) The production period for breeders and broilers is not varied 

 in length. 



(c) Seasonal variations in feed conversion are ignored thus keeping 

 the quantity of feed produced and distributed each day by each firm 

 constant. 



(d) Feed deliveries during any one day are planned to be primarily 

 confined to an erea segment equivalent to one-fifth of the poultry pro- 

 ducing area, the daily requirement set by a 5-day week. This arrange- 

 ment reduces to a minimum the intraband travel. The truck proceeds to 

 one or more units and returns by the same route. 



(e ) Broiler flock sizes of a single age group are 4,800 birds in Band 

 L 9.600 in Band II, 14,400 in Band III, 11,200 in Band IV, and 20,000 in 

 Bands V and VI. 



(f) Mature breeder flock sizes consist of 2,595 birds in Band I, 

 5,190 in Band II, 7,785 in Band III, 6,055 in Band IV, and 5,405 in Bands 

 V and VI. Birds in these flocks consist of several age groups. 



(g) Replacement flock sizes average 1,343 birds in Band I. 2.686 in 

 Band II, 4,029 in Band III, 3,364 in Band IV, and 3,014 in Bands V and 

 VI. 



(h) The work day for each truck and driver cannot exceed ten con- 

 secutive hours. This assumption prevents the shifting of the effects of an 

 increasing producing area onto drivers and trucks through use of over- 

 time payments and increased truck utilization. 



(i) Each truck and driver can undertake only those trips that can 

 be completed in ten hours or less. This means that a truck and driver 

 cannot initiate a trip one day and return the next. 



(j) The quantity of feed delivered to a production unit plus the 

 quantity in bins at the production unit is restricted to the amount that 

 will be consumed in the following two weeks. The purpose of this as- 

 sumption is to simulate as closely as possible prevailing practices. 



(k) Only the quantities of each feed formulation as prescribed by 

 the adopted feeding practices are delivered to each production unit. 



2. Number and Size of Daily Delivery Orders — The feed tonnage 

 delivered to a production unit is a function of the projected feed con- 

 sumption for the following two weeks, as determined by the size and age 

 of flock and the compartment size of the truck. Considering these factors 

 simultaneously with the intent of utilizing the maximum hauling cap- 

 acity of the truck on each trip, the number and size of orders are es- 

 tablished for each of the six bands. 



Table 14 gives the daily delivery schedule for each band by formula- 

 tion, tonnage, and the number of truck body compartments needed to 

 transport each order. Many of these orders are in units of or multiples 

 of three tons which provides for maximum use of feed compartments. 

 Orders for formulations in other tonnage units result from either the as- 

 sumption concerning the amount of feed allowed to be in storage at a 

 production unit or the balance needed to finish feeding a particular 

 formulation.
