It is observed that there is a fairly good agreement between the medullation
figures obtained by these two methods.
The exact relationship which seems to exist between the fineness of the fibres
and their medullation formed a subject of a close study in the present work. It may
be remarked that among the well developed breeds of sheep, even in coarse fibres
(40-50µ), there is hardly any medullation, but in most of the Asiatic breeds, this
defect is far too common.
During the course of work it was noticed that fine wool with fibre diameter
below 30 microns was rarely medullated, whereas with increasing coarseness medu-
llation greatly increased.
The diagram for diameter frequency (Fig. 1) wherein the medullated and non
medullated fibres are plotted in a distinguishable manner, showed that generally
below 30 microns the fibres were non-medullated, while between 30 to 40 microns
the medullated fibres were few in numbers. Beyond this limit almost all the fibres
exhibited medullation.
In order to bring out any quantitative relationship which may, therefore, exist
between the total fibre diameter and the diameter of the medullated part, a large
number of measurements were carried out.
The results are recorded in Fig. 2, wherein the internal diameter of the medu-
llated portion is measured against the total diameter.
The linear trend of the points is clearly indicated in the diagram, and a mean
line extrapolated to zero medullation cuts the diameter axis at 26 microns. It is
thus obvious that medullation below this fineness does not generally occur.
The same relation was found to hold good when similar observations on the
cross-sections of the medullated fibres were plotted (Fig. 3). Table II is made up
from these observations which may be expected in a fibre of given diameter.

The third column in Table II indicates an interesting fact that the difference
between the total diameter and its medullated portion is constant and is independent
of the total diameter of the fibre.
The microprojection method described above, however, consumes a good deal of
time and has to be necessarily carried out in the dark room together with the fineness
assessment. It was therefore of interest to see if other quicker methods either physical
or chemical were available which would assess medullation, preferably in bulk.
Amongst the physical methods which were likely to be of use, the tensile strength
and the resilience measurements of the samples were considered suitable for a
preliminary study. Relation between the tensile strength of the fibre and its degree
of medullation is not very definite on account of the generally heterogeneous nature
of the fibre, but a general decrease of strength in medullated fibre has been observed.
Resilient measurement in bulk seems to be more promising as it relates the resilience
characteristics of wool with its quality.
Colour of wool also plays an important part in assessment of its quality. Wool
from the more domesticated breeds of sheep is always nearly white. Quite a large
portion of Indian wool especially from South and East is found to be coloured as
grey, brown or black. This is another factor which lowers the value of Indian wool.
Even in white wool there are various grades as white, dirty white, creamy white,
pale yellow or yellow. It is difficult to judge the colour of a single fibre and this
is usually done by visual examination of the samples in bulk. The Indian Standards
Institution has set up certain standard specifications for such a classification for
commercial use.
Amongst the chemical methods available sulphur content of wool which is known
to vary between 2.3 to 4.1 per cent is regarded by some workers as dependent on the
quality of the fibres. A great deal of uncertainty is, however, attached to the sulphur

INDIAN WOOL
III. QUALITY OF WOOL PRODUCED BY SHEEP BREEDS, OF INDIA

(Received for publication on 12 September 1952)
INDIA produces annually nearly fifty five million pounds of wool. Of this
about half is exported, mostly for the manufacture of carpets. However
like cotton, Indian wool in common with other Asiatic wools, is of a considerable
coarser type as Compared to the much finer qualities produced in other countries
notably Australia. Indian wool consumed in this country and abroad is useful
only for coarse quality goods such as blankets, carpets, cheaper qualities of felts
and as a lining material for clothings made from finer wools. Indian woollen mills
producing yarns and cloth for the worsted and clothing types of material, mostly
use foreign wools or blends of foreign and Indian wool of selected varieties from
Kashmir and Tibet.
It is likely to be presumed from what has been said about Indian wool, that
this country is incapable of growing fine wool or that there is no scope in this country
for developing goods breeds of sheep with fine homogeneous and non-hairy type
of wool. India does produce a fine quality of wool, such as the undercoat of
fine-wooled Pashmina goat of the Kashmir frontier, but the production of this wool
is however, extremely limited and the question of increasing the population of this
animal on its own habitat and in other parts of the country still needs a systematic
investigation.
The general survey of the literature unfortunately shows, that there has never
been an extensive attempt to study the quality of wool produced by the indigenous
sheep of this country. The present attempt under the patronage of the Indian
Council of Agricultural Research perhaps represents a pioneer effort on such a big
scale. Before making any attempts towards producing better quality of wool
it is absolutely necessary to have a general survey of what we have at present. The
data presented helps to do it to a great extent to isolate and locate the local breeds
producing good wool and indicates the potentialities for further development. It
is not always possible to get data according to breed, since such a separation of sheep
according to breeds has not been done so far. In such a case the data on the regional
basis is presented which it is felt is the nearest approach to the understanding of the
quality of wool being produced in the country. Such a data has amply shown that
there do exist sheep producing wool comparable with the Merino quality 56'8 and
58'8. These breeds of sheep are found in the Kashmir State (Karnah and Gurez)
in the Punjab (Hissar dale), in the Niligiri (Ootacamund), in Gujerat (Patanwadi),

those with 0 per cent, 1-10 per cent, 11-35 per cent and above 35 per cent medullation.
KASHMIR BREEDS
Indigenous breeds
Wool samples received from the Government Sheep Breeding Farm at Banihal
in Kashmir indicated that there are four principal breeds of animals found in this
part of the country. These are recognised as the Karnah, Gurez, Bhadarwah and
the Bakarwal breeds.
Forty-seven samples (16 Gurez, 16 Karnah, 14 Bhadarwah and 1 Bakarwal)
were analysed for their fibre characteristics.
It is observed from Table I that the majority of the samples in all the four
breeds of sheep, viz. Gurez, Karnah, Bhadarwah and Bakarwal, lie within the range
of 76-100 mm. with respect to length, 26-40 microns with respect to diameter, 26-45
per cent with respect to C. V. and 1-35 per cent with respect to medullation.
The detailed analysis shows that of the Kashmir breeds, Karnah wool is the
• best of the four types, while Gurez and Bhadarwah occupy the intermediate posi
tion between Karnah and Bakarwal.
Cross-breeds
A very important batch of samples were received from Kashmir farm in three
lots consisting of 195, 105 and 116 samples representing the cross-breeding experi
ments with Merino rams. These include samples from the various stages of cross
breeding as ½, 3 / 4 , ⅞, ¼ and F 1 bred animals. The analysis is given in Tables II, III
and IV corresponding to the three lots of samples received during different years.
It is interesting to study this data according to the degree of cross-breeding. The
data is compared in three series, consisting of the comparison of the local with ½,
3 / 4 and ⅞ bred, local with ¼ bred and local with F 1 bred respectively.
Ewes, local ½, 3 / 4 and ⅞ bred
The data consists of analysis of samples from 119, ½ bred; 55, 3 / 4 and 2, ⅞ bred
ewes. The tables show a definite decrease in diameter successively in the ½ bred
and 3 / 4 bred animals over the local ewes. Of the 119 samples 61 samples have diameter
below 25 microns and 52 between 26-40 microns as compared to local ewes in which
case 12 of the 17 animals have diameter between 26-40 microns and none below
25 microus, and five above 40 microns. The coefficient of variation also decreases
with 26 and 82 samples in the first two ranges of C. V. as compared to 1 and 10
of the local ewes samples. The wool quality shows a further improvement in the 3 / 4

medullation. The F 1 generation Merico ewes are comparable with the ½ bloods
except that there is a slight deterioration in the fibre homogeneity. Wool from
the castrated ram of this generation is finer than that of non-castrated animal but
it slightly loses in quality in points of homogeneity and medullation.
MADRAS PROVINCE
Nilgiri breeds (Oolacamund)
Recently an interesting breed of sheep known as Nilgiri breed has been located
near the area about Ooty. It is interesting because the wool is perhaps of the finest
quality amongst that produced in South India, and the breed is one of the very
few fine quality wool producing indigenous breeds of sheep. The only other breed
to which it can be compared are the few breeds from Kashmir and few from Bikaner.
The origin of this breed of sheep is obscure but it is believed that the origin
must be perhaps the two famous British breeds which were imported by British
planters in Nilgiri and which are found in the hilly regions of England, viz. South-
down developed in the chalky hills of Sussex and Chaviots, the native of Chaviot
on the border between England and Scotland. The Nilgiri breed is also found
mainly over 6,000 feet.
It must be noted that this breed has been neglected for some time past and
hence some deterioration may have set in the wool quality. It is therefore believed
that this enterprise of the Madras Government is quite promising.
Ooty
Two hundred and seventy three samples in two lots of 54 and 219 were received
from Ooty for fibre analysis. The first lot of Nilgiri breed consisted of six rams
and 48 ewes while the second lot consisted of 20 rams, five ram lambs, 189 ewes and
five ewe lambs. The variation in their fibre characteristics with the number of
samples falling in each group of length, diameter, C. V. and medullation are given
in Table V.
It is observed that out of 273 samples, about 95 samples have fibre fineness
below 25 microns, about 177 samples between 26-40 microns and only one sample
above 40 microns. As far as C. V. is concerned about 96 are homogeneous and
190 samples are moderately homogeneous and only 13 samples are heterogeneous.
About 106 samples are completely free from medullation, while 76 samples have
medullation between .1 and 10 per cent and 95 samples lie between 11 and 35 per
cent. Only five samples have above 35 per cent medullation. It is observed
on the whole that this particular breed of sheep produces medium fine, moderately
homogeneous and slightly medullated wool. Most of the samples fall within the
range 1/2 blood to 3/8 blood according to American Standards or 60's to 56's accord-
ing to the British Standards.
Bellary breeds
Five hundred and twenty two samples were received from various farms
for fibre analysis. Table VI gives the variation in their fibre characteristics with
the number of samples falling in each group of length, diameter, C. V. and medu-
llation.

INDIAN
WOOL
III.
QUALITY
[Vol. XXIII, Part.II,
It is observed from the table that out of 522 samples of wool examined, about-
96 per cent have diameter above 40 microns while only 4 per cent have diameter
below 40 microns. This shows that the fibres are of very coarse and inferior nature.
All the samples are highly medullated and very heterogeneous. Due to its high
degree of coarseness, heterogeneity and medullation, the samples can be used only
for carpet or heavy woollens. The samples are from animals collected in the farms
from the breeds existing in that area. The individual breeds are not indicated
and hence are grouped as Bellary samples. The detailed analysis as well as the
abridged table shows that there is no major variation in the fibre characteristics
in various animals and hence the results stated here can be taken as representative
of wool produced in the party of the country it covers.
Coimbatore
The analysis figures of 22 samples (Polayakothai nine, Sulur seven, Kane-
polian five and unnamed one) are shown in Table VII.
It is seen from the table that few samples of Coimbatore have medium quality
wool comparable to Bikaner type, while the rest of the samples represented coarse,
heterogeneous and medullated wool like the samples of Bellary breed.
UTTAR PRADESH
Meerut
One hundred and twenty-two samples were received from the Deputy Director of
Animal Husbandry, Meerut, in three lots: The first lot consisted of 58 samples
collected from local sheep from various villages near about Meerut as shown in
Table IX. The other two lots were 41 samples from local sheep and 23 samples
consisting of seven local breed and nine purchased rams and seven of their first
progenies. The analysis of the samples is shown in Table X. The details of the
58 samples show that of the 58 samples, 38 have diameters above 40µ and 21
between 26-40µ. The samples are appreciably medullated since practically, all
the samples fall in the third and fourth range of medullation.
The analysis of the second lot of 41 samples consisting of 22 local ewes selected
from different villages other than those in the first lot and 19 first progenies from
goat rams shows that the ewes have a better quality wool than those in the first
lot and the first progenies show a further improvement in fibre characteristics.
Gwaldam
Forty-one samples were received from farm in Gwaldam (Dist. Almora) in two
lots. The analyses of the samples is given in Table IX. The first two lots, consisted
of 27 and 14 samples from local Garhwal and Rampur sheep. The analysis shows
that the wool is of medium quality with about 50 per cent of the samples having
diameter between 26-40 microns and other 50 per cent above 40 microns. The
samples are moderately medullated with 35 per cent and 55 per cent of samples
lying between the second and third range of medullation. The samples hence
are of medium quality wool.
