ABSTRACT

The paper analyses quantitatively the productivity of veterinary

sciences literature contributed by Indian Scientists. The data,

for 1999 – 2011, used in this study were obtained from the ISI

Web of Science database – Science Citation Index Expanded

(SCIE). A total of 5468 publications of two types namely

journal articles (5418) and conference proceedings (50). The

aim of the paper was to ascertain annual research output,

authorship pattern, forms of publications, highly productive

authors, subfield wise distribution, and ranking of journals of

veterinary science literature in India.

Keywords: Bibliometrics, Veterinary Science, Dairy &

Animal Science, Marine & Freshwater Biology, Reproductive

Biology.

INTRODUCTION

Bibliometrics is the quantitative evaluation of scientific literature1. Scientific

productivity is influenced by a large number of factors, including individual

characteristics such as age, gender, psychological traits, and educational background, as

well as structural features like funding, institutional context, and the organization of the

actual research2-4

. Bibliometric analysis is used in the science and technology policy

arena to determine the knowledge outputs of the national systems of innovation5. In view

of the above, it was intended to aim at analysing the scientific productivity of veterinary

sciences in India. The study aims to ascertain the growth of literature and productivity of

authors from the Indian point of view.

DATA SOURCE AND METHODOLOGY

The data were retrieved from the ISI Web of Science database – Science Citation

Index Expanded (SCIE). The search strategy for general search of veterinary science

literature was as follows:

Topic= veterinary science; DocType=All documents; Time Span=1999-2011;

Address=India.

Thus, A total of 5468 publications of two types namely journal articles (5418) and

conference proceedings (50). The collected data were analysed using MS-Excel

Spreadsheet and MS-Word.

BIBLIOMETRIC INDICATORS

Degree of Collaboration

To examine the extent of research collaboration among the veterinary scientists in

India, Subramaniam’s6 formula was adopted. It can be statistically proposed as:

sm

m

NN

NC

+

=

Where,

C = Degree of collaboration

Nm = Number of multiple authored papers

Ns = Number of single authored papers

RESULTS AND DISCUSSION

The analyses, based on the data collected, were carried out with a view to measure

the growth of literature over the study period, ranking of journals, subfield-wise

distribution of articles in journals, etc.

Annual research output

Table 1 shows the findings of year-wise distribution of total research output of

veterinary science literature in India. It was observed that the veterinary science literature

of India is growing steadily during the period but for 2009 and 2010 when it has come

down. Yet the decreasing trend was observed in the years 2000, 2003, 2009 and 2010.

The study examined totally 5648 research output for a span of 13 years. As a result, the

growth of total research output was increasing gradually, which is accounted from 462 in

1999 to 624 in 2008. However, the trend from 2009 onwards was a reverse as there was a

sudden decrease in 2009 and it continued to remain.

2011 217 3.97 100.00

Total 5468 100.00

Authorship pattern and degree of collaboration

Table 2 clearly indicates that three authored papers rank first in order sharing

25.46 per cent of the total research output. The four authored papers follow second in

order with 22.07 per cent of the total research contributions followed by two, five, and six

authored contributions sharing 21.74 per cent, 13.3 per cent, and 6.31 per cent of the total

research output during the study period respectively. However, It is interesting to note

that single authored papers occupy sixth position in order witnessing 261 contributions

which represents only 4.77 per cent, on the other hand seven, eight, nine, and ten or more


14

authored contributions record 2.94%, 1.81 %, 0.84 %, and 0.75 % respectively. An

attempt was made to analyse the nature of collaboration among the veterinary science

researchers in India. The result of degree of collaboration (0.95) clearly indicates that the

research output of veterinary science literature in India is fairly collaborative.

Source-wise distribution

The source wise distribution of research output of veterinary science literature, as

can be seen in Table 3, revealed that the journal articles occupy the highest percentage of

output yielding 99.09% followed by conference proceedings 0.91%.

Subfield wise distribution

The literature of veterinary science (5468 records) retrieved from web of science

was divided into 11 subfields. Out of which, Veterinary Sciences, Multidisciplinary

contributing 4697 publications that amount to 85.90 per cent ranks first in order followed

by Immunology (3.51%), Dairy & Animal Science (2.69%), Parasitology (1.59%),

Marine & Freshwater Biology (1.43%), Reproductive Biology (1.35%), and Entomology

(1.06%). The remaining subfields namely Microbiology, Mycology, Infectious Diseases,

and Anatomy & Morphology share less than 1 per cent. However, the highest

concentration was observed in Veterinary Sciences, Multidisciplinary while the lowest

contribution was seen in Anatomy & Morphology.

Ranking of Journals

The literature of veterinary science covered in web of science for the period 1999-

2011 is a total of 5418 articles published from 98 journals. The ranking of journals based

on their productivity has been presented in Table 6. From the result, it is quite surprising

that one Indian journal ‘INDIAN VETERINARY JOURNAL’ alone published 3469 articles

that share 64.03 per cent of total publications. The remaining journals cover less than 4

per cent. The other ranked journals, which share between 2 and 4 per cent, include

VETERINARY PRACTITIONER (3.23%), VETERINARY RESEARCH

COMMUNICATIONS (2.92%), TROPICAL ANIMAL HEALTH AND PRODUCTION

(2.82%), JOURNAL OF CAMEL PRACTICE AND RESEARCH (2.29%), and FISH &

SHELLFISH IMMUNOLOGY (2.07%). The list of journals along with their ranking is

CONCLUSION

Bibliometrics is a tool to analyse literature and throw light on the literature and

the authors from different points of view. It was observed that the contributions made by

Indian veterinary scientists for a span of 13 years were quite considerable. Out of various

institutions, it was found that Punjab Agricultural University has contributed the

maximum followed closely by Tamil Nadu Veterinary & Animal Science University and

Madras Veterinary College. As far as the individual contributions are concerned Punjab

Agricultural University occupies the first two positions. It is remarkable that only journal

out of 99 journals, ‘Indian Veterinary Journal’ covers about 65 per cent of the total

publications. A unique observation that the Indian contributors to veterinary science

literature have made their research publications in two forms only – journals and

conference proceedings. More such studies could be conducted and brought to light to

help finding areas need improvement.
