between the chicks fed the first two rations. In large quantities rice bran
was unsatisfactory for growing chicks.
There was no marked difference in the amounts of feed consumed by the
different lots. In economy, corn meal was better than corn bran or a combination
of corn bran and rice bran. For growing stock the rice bran and
corn meal combination was better than corn bran or rice and corn bran.
Chicks fed corn bran alone or in combination were less vigorous than those
fed corn meal alone or in combination. There was no gr&at difference in the
individual growth rates of the chicks fed corn bran and those fed corn and
rice bran.
Notes on locust meal as a poultry feed, F. M. FRONDA (Philippine Agr., 24
(1935), No. 5, pp. 425-427).-A preliminary test using two lots of three chicks
each was conducted at the College of Agriculture. The results of the chemical
analysis indicated that locust meal could be profitably used as a source of
protein for chicks. If used to supply the optimum level of protein it may
increase the crude fiber content of the ration beyond a desirable point. Locust
meal was not as efficient but was as palatable as fish meal.
The value of cassava refuse meal in the ration for growing chicks, T. T.
TABAYOYONG (Philippine Agr., 24 (1935), No. 6, pp. 509-518, fig. 1).-This work
was undertaken at the College of Agriculture to compare the feeding value of
cassava refuse meal with rice bran for feeding chicks. For this study three
hatches of chicks were divided into three lots of 80, 80, and 47 chicks each.
Chicks fed rice bran grew faster than those fed cassava refuse meal, while
chicks fed a combination of the two feeds were intermediate in rate of growth.
The chicks fed rice bran consumed the largest amount of feed, while consumption
in the other lots was about equal. The cost of feed was highest in the
rice bran lot and lowest in the cassava refuse meal lot, while the amount of
feed per unit of gain was highest in the cassava refuse meal lot and practically
the same in the other lots. The lot fed cassava refuse meal had a
mortality of 59.4 percent, the rice bran 41.5 percent, and the lot fed the combination
of the two feeds 42.5 percent. The chicks in the rice bran lot were
the most uniform in size, while those in the cassava refuse meal lot were
the least uniform. Using the rice bran ration as 100, the cassava refuse
meal ration was only 77.3 percent efficient, while the combination of the two
feeds was 92.3 percent efficient.
The vitamin A requirements of hens for egg production, R. M. SHERWOOD
and G. S. FEAPS (Texas Sta. But. 514 (1935), pp. 21).-This study was conducted
to secure further information (E. S. R., 69, p. 95) on the vitamin A requirements
of hens and the number of units of vitamin A potency in the feed over
maintenance required to produce vitamin A in the eggs. White Leghorn hens
were divided into three groups and fed different amounts of vitamin A from
yellow corn and dehydrated alfalfa leaf meal.
No significant differences were observed in the weights of the birds in the
three groups, but the mortality was greatest in the lot receiving the least
vitamin A. In general, the lots receiving the least vitamin A had the lowest
egg production, while the highest production was in the lot receiving the most
vitamin A. Hatchability was from 33 to 42 percent in the lot receiving the
smallest amount of vitamin A, and from 69 to 79 percent in the other lots.
The units of vitamin A per gram of feed required for the formation of feathers
appeared to be as high as the requirements for egg production. There appeared
to be no storage of vitamin A during the molting period.
The apparent percentage of vitamin A recovered in the eggs averaged about
25 percent of that in the feed, but the percentage recovered during different
months varied from 8 to 39. The highest apparent recovery was just before or
