ABSTRACTS OF BULLETINS 305 TO 327, INCLUSIVE
' A. 1). JACKSON

The general mailing list of the Agricultural ‘Experiment Station
has become so large that it is not feasible to publish a sufiicient num-
ber ofcopies of every bulletin to send a copy to every name on the
list. The following brief abstracts of recent bulletins published have
been prepared for circulation to the entire mailing list. It is the pur-
pose to give the reader an abstract of the matter contained in the
bulletin and if one receiving this list of abstracts is interested in any
particular bulletin shown herein, it will be sent to him on application.
In cases where the supply of a bulletin has been so nearly exhausted
that only a few reserve copies are on hand, arrangements will be made

to lend these reserve copies to those who will agree to return them

for further use.

Bulletin No. 305—Swine Feeding Experiments.

This bulletin includes reports of five difierent experiments, two of which
deal mainly with growing pigs and three with fattening mature pigs.

The first experiment was planned to test out the value of tankage and
pasture in raising pigs from birth to maturity. At the age of eight
months the pigs which had been fed milo when in a dry lot weighed only
twenty-one pounds each and had no selling value. Those which had been
fed milo and tankage in a dry lot weighed 157 pounds and showed a profit
of $1.54 per pig. Those which had access to pasture weighed 249 pounds
and showed a profit of $4.59 per pig. Those which had been fed only milo
in the dry lot until weaning time and had then been given pasture and
tankage weighed 202 pounds and showed a profit of $3.73 per pig.

The second experiment was planned to study the value of dried butter-
milk as compared with tankage for pigs after weaning, and also to study
the results of adding shorts to a ration of milo chops supplemented with
tankage or dried buttermilk. Dried buttermilk proved to have a value
superior to that of tankage pound for pound, but on account of its higher
price was less profitable. Also some trouble was experienced with the pigs
going ofi’ feed when large amounts of dried buttermilk were fed. There
was no advantage gained by adding shorts to the ration.

The third experiment was planned to compare Whole cottonseed, cotton-

seel meal, and tankage as supplements to milo chops when fed to fatten- _

ing hogs. Four lots of ten pigs each were used. The lot which received
the Whole cottonseed refused t0 eat it and picked out the milo and tank-
age and left the cottonseed in the trough. This lot was, therefore, dis-
continued and no definite results with regard to the cottonseed were
secured except the fact that it was not palatable. Tankage and milo proved
superior to cottonseed meal or to a combination of cottonseed meal and
tankage with milo. One pig died of cottonseed meal poisoning in the lot
which received the largest amount of cottonseed meal. »

The fourth experiment was planned to show the effect of grazing on a
peanut pasture on the quality of pork produced after fattening. The
effects of using a free choice self-feeder as compared with hand-feeding
were studied. Soft pork was produced by the lot which was on peanut
pasture the entire feeding period, and some soft and some hard carcasses
by the lot which was on peanut pasture only during the first half of the

feeding period. The successful use of the free choice self-feeder requires.

4 BULLETIN NO. 338, TEXAS AGRICULTURAL EXPERIMENT STATION

that only those feeds be used which are palatable to the pigs and with
which they are familiar.

The fifth experiment was undertaken to find out the firmness of pork
produced by, six different rations fed to fattening pigs and also to find
out how these rations compared with each other in the amount and
economy of the gain which they produced. Milo chops seemed a little
superior to corn chops. Cottonseed meal gave good results as a protein
supplement. Wheat shorts fed in large amounts was not a very satis-
factory feedl Rice bran was only fairly satisfactory and produced softer
pork than the other rations, although not soft enough to be penalized at
the market.

Bulletin No. 306-—Grain Sorghum Versus Corn for Fattening
Lambs.

This bulletin summarizes the resultsof previous work on this question
(Bulletins Nos. 269 and 285) and gives the results of the third year’s test
which was undertaken on a larger scale than the previous work.

No significant diflerence was found in the feeding value of corn chops,
milo chops, and kafir chops, all of which were more valuable than the
other seven feeds. Fetcrita chops, darso chops, sorgo chops and Whole
milo all proved to have about the same value pound for pound and were
only a little less valuable than the three first mentioned. Kafir heads and
milo heads and feterita heads were the least valuable of the ten feeds
tested; but they proved to have a high feeding value. All lots brought
the same price on the Fort Worth market and seemed to be equally well
finished. The feeding values of these ten feeds are calculated and given
in therms. The values of these ten feeds are so near together that still
more work needs to be done to determine accurately the difference between
them.

Bulletin ‘No. 307—Texas Root Rot of Cotton and Methods for‘

Its Control.

Texas root rot is a disease of cotton caused by a parasitic fungus. It
is most commonly found in blackland soils. It attacks the roots _not only
of cotton plants but also of many other woody plants, including many
trees and common weeds. The fungus is transmitted chiefly through root
contact. It seldom produces the spore or seed stage except under exceed-
ingly favorable conditions of moisture and temperature. This fungus is
carried over winter on live roots of cotton and weeds. It has been found
that as long as a single root remains alive in the soil it may carry the
fungus through the winter. It has also been found that as soon as the
roots of an infected plant die, the fungus likewise dies and becomes in-
effective. It would seem in the light of our present knowledge of cotton
root rot that the best means of combating the disease is to kill the old
cotton plants by uprooting them in the fall and by ridding the land of
any Weed which carries this disease. The most common weeds which are
carriers are tie-vines, cockleburs and rag weeds. Grasses are not attacked
by this fungus. Good farm practice that rids the land completely of
carriers is the best recommendation at the present time.

Bulletin No. 308—'The Sweet Potato Weevil.

This pest is found chiefly in the southeastern one-third of Texas.
Elaborate notes are made on the life history of the insect, for aid in
developing control measures. No important natural enemies have been
discovered. Quarantines and cultural methods offer some relief. Plant-
ing weevil-free slips, spraying with arsenical poisons, prompt harvesting,
and storage of only weevil-free potatoes are the remedial measures offer-

ABSTRACTS OF BULLETINS 305 TO 327, INCLUSIVE 5

ing greatest promise. Fumigation with carbon disulphide kills the weevils
in all stages but hastens decay of the potatoes.

Bulletin No. 309- I. Fattening Steers on Cottonseed Meal
and Hulls with and Without Corn.
II. The Influence of Age 0n Fattening
Steers.

The ration which included corn was slightly more satisfactory than
cottonseed hulls and meal alone. Cottonseed meal and hulls should not
be full-fed for more than 90 to 100 days. The average cost of 100 pounds
of gain was $11.81 per steer for the older steers compared with $9.94 for
the younger steers. It is probably cheaper to ship steers to the feed
than to pay freight on feed. Cattle feeding should be regarded as a method
of marketing the surplus feed of the community.

Bulletin No. 310—The Interpretationpf Correlation Data.
The uses and limitations of correlation tables in the interpretation of
biological data are discussed and illustrated. This bulletin is of interest
chiefly to students and investigators.

Bulletin No. 311—The Influence of Individuality, Age and Sea-
son Upon the Weights of Fleeces Produced by
Range Sheep.

Culling the animals of low production from the flock will increase the
average weight of fleece for the flock and will increase the- wool-producing
qualities of the next generation. In general, it may be said, “Once a
good sheep, always a good sheep; once a poor sheep, always a poor sheep.”
In the interest of economy sheep should be culled as young as possible.
Culling is not so reliable after a drouth. The fleeces are the heaviest at
two and three years. Wethers produce heavier fleeces than ewes at every
age excepting as yearlings. No decided decrease in wool production due
to age was noted among eight-year-old ewes in the Experiment Station
flock. Practical methods of culling according to the weight of the fleece
are discussed.

Bulletin No. 312-Commercial Fertilizers in 1922-23.

The year showed a great increase in fertilizers sold in Texas, there
being 73,300 tons sold as against 33,000 tons the year previous. Eleven
standard formulas designed to‘ meet practically all needs for mixed fer-
tilizers in Texas are shown and their general adoption recommended. The
formula to be selected and the amount and the method of use for various
crops and on various soils is suggested. General fertilizer information is
given, also a table showing the analyses of all commercial fertilizers placed
on the market during the season. -

Bulletin No. 313-—R1ce Bran and Rice Polish for Growing and
Fattening Pigs.

This bulletin summarizes briefly the results of two experiments con-
ducted at this Station during 1922-23. Rice polish seemed to have about
the same feed value as corn chops, but ‘when fed in large quantities caused
digestive disturbances. Pigs would not eat as large an amount of the
ration containing rice polish as they did of the ration which contained
only corn chops and tankage. One of the twenty pigs which received the
rice polish killed out slightly soft. Eleven of the twenty pig's which re-
ceived rice bran in the same experiment killed out slightly soft. The
use of rice bran in the ration lowered the rate of gain and increased the

6 BULIQETIN NO. 338, TEXAS AGRICULTURAL EXPERIMENT STATION

amount of feed required for 100 pounds of gain as compared to rations
consisting of corn and tankage alone. Rice bran seemed to be less val-
uable during the growing period than during the fattening period for
swine. Rice bran produced soft pork when fed in large quantities for a
long time. It seems fairly certain from these experiments that rice bran
must be purchased at a considerably lower price than corn before it can
be fed profitably in large amounts to pigs and that it cannot be fed for
a very long time without some danger of producing soft pork.

Bulletin No. 314-Commercial Feeding Stuffs.

This bulletin reports the examination of feeding stuffs found in the
markets of Texas during the year ended August 31, 1923. It presents a
summary of the Texas feed law and gives sundry information for feed
manufacturers and consumers. lt contains a complete table of results
of the inspection work for the year. '

Bulletin No. 3-15—Digestion Experiments with Oat By-Prod-
ucts and other Feeds.

This is a progress report on digestion experiments to secure informa-
tion regarding the feeding values of various feeds as shown by their
productive value and digestible protein. The feeds reported on are alfalfa
meal, corn cobs, cottonseed hulls, kafir head stems, live-oak leaves, mes-
quite beans, oats, oathull clippings, oatmeal by-products, rice bran, and
rice polish.

Bulletin No. 316—The Soils of Brazos, Camp, Ellis, and Wash-
ington Counties.
The chemical composition of samples of typical soils from these four
Texas counties is presented and discussed. Means of increasing and main-
taining soil fertility of the various types of soils found in these counties
are discussed. Soil survey descriptions of the various types of soils of
the four counties are presented.

Bulletin No. 317—Comparative Influence of Various Protein
Feeds on Laying Hens.

Cottonseed meal may be used as a substitute for meat scrap and tank-
age in a ration forlaying hens when the cottonseed meal is fresh. The
cottonseed meal gave the best results in a ration composed of wheat bran
125 pounds, gray wheat shorts 75 pounds, cornmeal 75 pounds, and cotton-
seed meal 120 pounds. When only limited quantities of fat-soluble A
vitamin were present in the ration the mortality of the hens was high
and the egg production low, ~

Bulletin No. 318—The Relations Between Rents and Agricul-
tural Values in Theory and in Practice.

This bulletin is intended to point out some of the basic factors that are
influencing land values and shows the relation that exists between the
financial returns from land, or its rent, and the value of the land.

Land values are first shown theoretically to be the summation of all
future rents discounted at a rate of interest that reflects our preference
for the present over the future. The difficulty of accurately forecasting
what rents and discount rates are going to be is noted. Other factors
besides prospective rents are suggested as partial determinants of land
values, thus still further complicating the problem of scientific land
appraisal.

The major portion of the bulletin is given over to a statistical study

ABSTRACTS OF BULLETINS 305 TO 327, INCLUSIVE 7

of the relation of rents to agricultural land values in Brazos, Williamson,
and Dallas Counties, Texas. In the absence of cash rentals in these coun-
ties it was necessary to devise a means of obtaining the cash equivalent
of the share rent. The method used as well as the results obtained are
shown in full in the text of the paper and in the tables appended. For
purposes of comparison, data from other states are either shown or ref-
erences given.

Bulletin No. 319—Field and Laboratory Notes on a Fatal Dis-
ease of Cattle Occurring on the Coastal Plains of
Texas. (Loin Disease.)

The outbreaks of the disease simulate an infectious disease, but in re-
peated experiments pathogenic organisms could not be isolated. The cause
of the disease is tentatively ascribed to toxins produced by bacterial action
in carcass material on the prairie and the consumption of such putrid
material by cattle. It is tentatively recommended to feed fresh feeding
bone meal to cattle, also to thoroughly clean all pastures of all animal
carcasses. Further investigations are being made.

Bulletin No. 320—Influence of Individuality, Age and Season
Upon the Weights of Fleeces Produced by Angora
Goats under Range Conditions.

Weights of fleeces of nearly 1200 Angora goats kept under range con-
ditions on the Ranch Experiment Station near Sonora were studied to
note the influence of individuality, age and season and to determine suc-
cessful methods of culling for increased fleece weight. At the fall shear-
ing when the goat isa year and a half old is thought to be the most
reliable time to cull for improvement in the average weight of fleece pro-
duced by the flock. The female goat, like the female sheep, produces its

maximum weight of fleece in the second year of its life. Wether goats‘

may produce still heavier fleeces at later ages. Seasonal conditions in-
fluence the weight of mohair fleeces more than that of wool. Fall fleeces
of mohair are heavier than spring fleeces. Detailed instructions for cull-
ing are given. Culling is more effective, of course, in non-uniform flocks
than in standard bred flocks. Age does not seem to reduce fleece weights
much until after the goats are six or more years old. A

Bulletin No. 321—Cotton Variety Experiments at the Main
Station, 1912-1922.

' Yield of lint per acre is much more important than the percentage of
lint. Length of lint, While not as important as yield of lint, is more im-
portant than percentage of lint in seven-eighths-inch staple or longer. The
farmer in choosing a variety to plant should consider first its yield of
lint per acre; second, length of staple; third, quality or grade of lint;
and fourth, percentage of lint. The bulletin reports on about 150 varieties
of upland cotton grown during the eleven years from 1912 to 1922, and
shows the yield of each variety for each year and ranks the leading vari-
eties for various groups of years during the period.

Bulletin No. 322—Commercial Fertilizers in 1923-24.

Sales were 126,180 tons in 1923-24 against 73,300 tons for the previous
year and 77,400 tons in 1913-14, the record season until this year. Use
is recommended of the eleven standard formulas agreed on in June, 1923,
and adopted by the Station. Potash is shown to be much cheaper in
muriate or sulphate than in kainit. A table is given showing the rela-
tion of the guaranteed valuation to the valuation delivered by various

8 BULLETIN NC. 338, TEXAS AGRICULTURAL EXPERIMENT STATION

manufacturers. A table is given containing an analysis of the samples
of fertilizers collected by inspectors. Sales of fertilizers having the eleven
standard formulas were 12,145 tons.

Bulletin No. 323—The Price of Feed Utilities.

A method is given for calculating the prices of digestible protein and
productive energy in feeds. The relative prices of digestible protein and
productive energy vary considerably from time to time. The value of
various concentrates calculated from the digestible protein and productive
energy can be used to aid in deciding the most economical feed under
given market conditions. Fair agreement was found between the calcu-
lated values and current selling prices of most feeds. Bulk or volume is
an important factor in the price of purchased hay, fodder or other rough-
age, although the farm price of the protein and productive energy is prob-
ably much lower in roughage than in concentrates. There is a consider-
able margin between the feed cost of milk and its selling price; the similar
margin for pork is much smaller and with beef it is very small, showing
the importance of low priced roughage for the profitable production of
beef under present conditions.

Bulletin No. 324—Commercial Feeding Stufis.

' This is the report of the Feed Control Service for the fiscal year Sep-
tember 1, 1923, to August 31, 1924. It contains a table of results of the
inspection Work for the year and explanations'of the purposes of the
Texas feed law together with a brief history of the Feed Control Service
and also definitions of terms. The methods of measuring the commercial
value of feeding stuffs are discussed.

Bulletin No. 325—Efl"ect of Cropping upon the Active Potash
of the Soil.

A close relation was found between the potash removed by crops and
the active potash lost by the soil. The amount of active potash lost from
the soil in 409 experiments averaged 40.9 per cent of the potash removed
by the crop. Considering that successive extractions of the soil with the
solvents removed active potash, and that the soil also had a fixing power
for potash, the conclusion is that the active potash lost by cropping must
be less than the potash removed by the crops.

Bulletin No. 326—Breeding Experiments with Blackberries and
. Raspberries. ’

This is an account of sixteen years of breeding experiments withblack-
berries and raspberries. This bulletin contains descriptions of the behavior
of seedlings, hybrids, and compound hybrids of various berries; experi-
ments leading to the development of the Nessberry, an outgrowth of a
cross between a raspberry and dewberry, are described; and the horti-
cultural characters of the Nessberry are discussed and methods are given
for its successful propagation.

Bulletin No. 327—An Agricultural Economic Survey of Rock-
wall County, Texas.

The information secured from five hundred farm operators is consid-
ered representative of the blackland farming belt of Texas. Specific treat-
ment is given such questions as land classification and land utilization,
land tenure, size of farm, capital investment in farms, farm labor, farm
income, farm credit, and the marketing of farm products. The influence
of the-geographic features of the area and the historical setting are dis-
cussed. Of the farms studied 90 per cent of the land was improved and

ABSTRACTS OF BULLETINS 305 TO 327, INCLUSIVE 9

\\ of this 93 per cent was devoted to crops of which cotton made up 67 per

cent. Lack of gardens, orchards and pastures and absence of any general
use of legumes are noted. The farms averaged 106 acres in size, though
the typical group was found between 50 and 100 acres. The yield per
acre of farms of less than 50 acres was not enough greater to bring the
net income per farm to that of the larger farms. Only 6 per cent of the
investment in farm capital was devoted to machinery and live stock, the
remainder being in land and permanent improvements. About 9 per cent
of the total investment in farms was borrowed. Yield of lint cotton per
acre was the most important factor in the net income per acre.
