THE USE OF TOMATO PULP II BROILER FEED(A)

R. H. Harms and C. R. Douglas(3)


Disposal of cull tomatoes is a tremendous problem in the tomato-growing
regions of Florida. The accumulation of cull tomatoes in garbage disposal areas,
which results in a health hazard, has caused Florida growers to set up a pilot
plant for processing this material into a dried pulp with the possibility of using
it in animal feeds.

Experiments reported here were conducted to study the possibility of re-
placing alfalfa meal in broiler diets with tomato pulp.

Experimental Procedure

Experiment 1 One hundred and sixty Single Comb White Leghorn cockerels
were used in this experiment. At one-day of age these birds were intraocularly
vaccinated for infectious bronchitis and Newcastle disease and randomly assorted
into eight pens in an electrically heated battery brooder with raised screen
wire floor. At four weeks of age they were transferred into a finishing battery
where they were kept until termination of the experiment.

The composition of the two basal diets used in this experiment is shown in
Table 1. 7Vhen tomato pulp was included in the diet,, three pounds of tomato pulp
replaced an equal weight of alfalfa meal. Feed and water were given ad libitum.

All birds were individually weighed at eight weeks of age at which time
feed efficiency was calculated. The birds were then dressed and visually scored
for deposition of carotenoid pigments in the skin, deposition of fat in the
abdominal cavity, and degree of fleshing of the dressed carcass.

Experiment 2 One hundred and fifty two straight-run, day-old Vantress X
Vhite Plymouth Rock broiler type chicks were used in this experiment. At one-day
of age the chicks were vaccinated for infectious bronchitis and Newcastle disease
by the intraocular method and randomly assorted into six pens in an electrically
heated battery brooder with raised screen wire floor. At four weeks of age they
were transferred into a finishing battery where they were kept until the termi-
nation of the experiment.

The composition of the basal diet used in this experiment is shown in
Table 2. Either alfalfa meal or tomato pulp was used at a level of three per
cent of the diet in formulation of the two experimental diets. Feed and water
were given ad libitum.

All birds were individually weighed at eight weeks of age at which time
feed efficiency was calculated and the shanks of each bird were scored for
deposition of carotenoid pigments.

All statements of probability in this report are based on the analysis of
variance according to Snedecor (1956) with significant treatment differences
determined by Duncan's Multiple Range Test (1955).

Results and Discussion


Growth rate and feed efficiency of Single Comb -hite Leghorn cockerels or
Vantress X White Plymouth Rock broilers were not significantly affected by
replacing three per cent alfalfa meal with three per cent tomato pulp in their
diet (Tables 3 and 4).

The replacing of alfalfa meal with tomato pulp in the diet of Single Comb
White Leghorn cockerels did not affect their deposition of fat in the abdominal
cavity or the finish of the dressed carcass (Table 3).

Deposition of carotenoid pigments in the skin of hite Leghorn cockerels
were significantly reduced when the alfalfa meal in the diet was replaced with
tomato pulp (Table 3). The shanks of broilers fed a diet containing alfalfa
meal were found to be significantly deeper in yellow color than those of broilers
receiving the diet containing tomato pulp (Table 4).

These data would indicate that a level of three per cent of tomato pulp
may safely be fed to growing chicks. However, if it is used to replace alfalfa
meal the deposition of carotenoid pigments in the skin of the bird will be
significantly reduced.




Summary

Two experiments have been conducted to determine whether tomato pulp could
be used in chick feeds.

Growth rate of chicks, utilization of feed, deposition of fat in the abdomi-
nal cavity, and finish of dressed carcass were unaffected when alfalfa meal in
the diet was replaced by tomato pulp; however, deposition of carotenoid pigments
in the skin was significantly reduced.
