Background: Cattle are affected by many infectious and noninfectious diseases that can lead to economic losses to the farmers in terms
of reduced growth and production performance and mortality.
Objectives: This study was conducted to investigate the prevalence of infectious and noninfectious diseases of cattle in Chittagong dis-
trict of Bangladesh.
Methods: A total of 2614 clinical cases were diagnosed at five different veterinary hospitals in Chittagong district of Bangladesh during
the year 2013. Disease diagnosis was made on the basis of owner’s statement, general examination, clinical signs, gross pathology, and
laboratory procedures. Data were analyzed to determine disease prevalence in cattle with respect to breed, sex and season.
Results: Diagnosed diseases were categorized as infectious diseases, parasitic diseases, digestive disorders, metabolic diseases, respirato-
ry diseases and other diseases. According to our results, the prevalence of digestive disorders was the highest (45.14%) followed by para-
sitic diseases (30.64%), infectious diseases (9.49%), respiratory diseases (3.90%), metabolic diseases (3.18%) and other diseases (3.18%).
Disease prevalence was highest in Cross-bred cattle (44. 23%) followed by Red Chittagong cattle (28.46%) and Non-descript Deshi
(27.31%). Female were more susceptible to diseases (54.32%) than male cattle (45.68%). Disease prevalence varied according to seasons.
Highest prevalence was recorded in summer season (37.49%) followed by rainy season (34.81%) and winter season (27.70%).
Conclusions: Our large set of data on cattle disease prevalence in Chittagong district of Bangladesh provides valuable insight to design
and implement priority based research on specific disease and to take efficient control strategies against the diseases.

Bangladesh is an over populated, rural and agrarian country in the
world. Cattle are very important component of the mixed farming
system practiced in Bangladesh from long time. In Bangladesh,
similar to high population density, livestock population is also
high and near about 80% of population is employed in agriculture
and livestock farming (BBS, 2008). Livestock is a vital compo-
nent of rural economy in Bangladesh and is performing multifari-
ous functions such as provisions of food, draft power and
transport. Bangladesh earns foreign currency by exporting several
byproducts such as hides, skin, bone etc and now biogas is also
producing from cattle dung. The contribution of livestock in the
magnitude of Gross Domestic Product (GDP) is about 16.23 % in
Bangladesh (BBS, 2008).
There are about 22.53 million cattle and 14.69 million goat popu-
lation in Bangladesh (DLS, 2009). However, most of the animals
are weak and emaciated with non-satisfactory productive perfor-
mance due to malnutrition and diseases. Among the various con-
strains in the development of cattle, both infectious and noninfec-
tious diseases are the most important limiting factors that cause
significant mortality of adult cattle and neonatal calves each year
(Debnath et al. 1990, Debnath et al. 1995). It was reported that
variation in different cattle breed, their sex and environmental
factors greatly influence the disease prevalence in livestock ani-
mals including cattle (Alim et al. 2011, Sarker et al. 2011, and
Islam et al. 2014).
The present study was undertaken to investigate the prevalence of
cattle diseases considering breed, sex and seasons at five different
locations of Chittagong division in Bangladesh. The results of the
current study will provide an overall idea about the distribution of
diseases of cattle in the region which may assist researchers or
clinicians to design and implement priority based research on
specific disease and to take efficient control strategies against the
2.1. Study area and study period
This study was undertaken at five different Veterinary Hospitals
located at five different Upazila (sub-district) under Chittagong
district of Bangladesh namely Chittagong Veterinary and Animal
Science University Satellite Clinic at Potia Upazila; Veterinary
Hospital at Sadar Upazila; Veterinary Hospital at Hathajari
Upazila; Community Based Veterinary Clinic at Sithakundo
Upazila; Veterinary Hospital at Mirsorai Upazila. A total of 2614
clinical cases of cattle of different breed and sex were diagnosed
2 International Journal of Biological Research
during the period from January to December, 2013. The handling
of animals in the study was performed in accordance with current
Bangladesh legislation (Cruelty to Animals Act 1920, Act No. I of
1920 of the Government of the People’s Republic of Bangladesh).
2.2. Diagnosis of diseases
Diagnosis of diseases was made by general physical examination
of animals, clinical signs, gross pathology and laboratory proce-
dures. During general physical examination animal’s body condi-
tion, behavior, posture, gait, locomotive disturbance, pulse, respi-
ration, temperature, abdominal distension, defecation etc were
observed and/or recorded. Examination of different parts and sys-
tems of the body of sick animals were performed by using the
procedure of palpation, percussion, auscultation, needle puncture
and walking of animals. Owner’s complaints were taken into ac-
count while performing general physical examination of a sick
animal. Animal’s breed, sex, age etc were also recorded in regis-
tered book. Specific bacterial, viral, and fungal diseases were di-
agnosed on the basis of specific clinical signs and gross lesions
(Jones et al. 1996, Khan 2000). In some cases, confirmatory diag-
nosis were made by cultural and biochemical characteristics of
causative organisms following standard procedure. Parasitic infes-
tations were diagnosed by faeces examination under microscope
as described previously (Soulsby 1986). Blood smears were pre-
pared and examined under microscope after Giemsa’s staining
according to the methods described elsewhere (Hendrix & Robin-
son, 2006) to confirm hemoprotozoan infestation.
2.3. Data analysis
Diagnosed diseases were categorized as infectious disease, parasit-
ic disease, digestive disorder, respiratory disease, metabolic dis-
ease and other diseases for statistical analysis. Obtained data were
analyzed by using statistical software 'STATA/IC-11.0' where
descriptive statistics was expressed as proportion with 95% confi-
dence interval (CI). For Chi-square test, results were expressed in
percentage with P-value and significance was determined when
P<0.05. The influences of cattle breed, sex and season on the
prevalence of diseases were also analyzed.
A total of 2614 clinical cases were diagnosed and the diseases
were categorized as infectious disease, parasitic disease, digestive
disorder, respiratory disease, metabolic disease and other disease.
As shown in Table 1, the highest prevalence was recorded for
digestive disorders (45.14%) and the lowest prevalence was rec-
orded for metabolic diseases (3.18%). Prevalence of digestive
disorders (45.14%) and parasitic diseases (30.64%) were signifi-
cantly higher among six categories (p <0.01). Disease prevalence
in Cross-bred cattle (44.23%) was significantly higher (p<0.01)
than that of Red Chittagong cattle (28.46%) and Non-descriptive
Deshi (27.31%) and females were more susceptible to diseases
than male cattle (p<0.05) (Table 2). Significantly higher preva-
lence of diseases (p<0.05) were recorded in summer season
(37.49%) than in rainy season (34.81%) and winter season
(27.70%) (Table 3).

Overall prevalence of infectious diseases among six categories
was 9.49% which constituted foot and mouth disease (4.74%),
wart (1.41%), mastitis (1.30%), arthritis (0.73%), foot rot (0.34%),
ephemeral fever (0.27%), hemorrhagic septicemia (0.27%),
dermatophilosis (0.19%), rabies (0.12%), tetanus (0.08%) and
anthrax (0.04%) (Table1). The prevalence of infectious diseases
was highest in Cross-bred cattle (5.78%) and lowest in Non-
descriptive Deshi (1.19%) (Table 2). Females (5.13) were more
susceptible to infectious diseases than male cattle (4.36%) (Table
2) and the prevalence in summer, rainy and winter seasons were
2.98%, 3.60% and 2.91% respectively (Table 3)
In parasitic disease category, nine parasitic diseases were identi-
fied of which five were gastrointestinal parasitic diseases and four
were protozoan diseases (Table 1). Major parasitic diseases consti-
tuted fascioliasis (10.44%), myiasis (8.11%), paramphistomiasis
(6.08%), hump sore (2.64%), strongyloidiasis (1.65%), babesiosis
(0.80%), coccidiosis (0.46%), balantidiasis (0.27%), and
anaplasmosis (0.19%) (Table 1). As in infectious disease category,
Cross-bred female cattle were more susceptible to parasitic diseas-
es (Table 2) and the prevalence in summer, rainy and winter sea-
sons were 12.78%, 9.79% and 8.07% respectively (Table 3).
Highest prevalence (45.14%) was recorded in digestive disease
category of which simple indigestion was 15.99% followed by
anorexia (14.08%), ruminal acidosis (12.24%), ruminal alkalosis
(2.83%) (Table1). Considering breed, sex and season, prevalence
of digestive disorders were recorded as 20.09% in Cross-breed;
12.36% in Red Chittagong cattle; 12.7% in Non-descriptive
Deshi; 23.41% in male; 21.73% in female; 17.90% in summer;
16.49% in rainy and 10.75% in winter (Table 2 & 3).
The overall prevalence of metabolic diseases was 3.18% of which
milk fever constituted 1.26%; weak calf syndrome 1.03% and
grass tetany 0.88% (Table 1). Considering breed, sex and season,
prevalence of metabolic diseases were recorded as 1.38% in
Cross-breed; 0.76% in Red Chittagong cattle; 1.03% in Non-
descriptive Deshi; 0.35% in male; 2.83% in female; 0.54% in
summer; 1.39% in rainy and 1.30% in winter (Table 2 & 3).
The prevalence of respiratory diseases was recorded as 3.90% of
which aspiration pneumonia was 2.60% and upper respiratory
tract infection was 1.30% (Table 1). Considering breed, sex and
season, prevalence of respiratory diseases were recorded as 1.46%
in Cross-breed; 1.34% in Red Chittagong cattle; 1.11% in Non-
descriptive Deshi; 2.72% in male; 1.18% in female; 0.76% in
summer; 1.15% in rainy and 1.99% in winter (Table 2 & 3). In
other diseases category, surgical affection, skin diseases, repro-
ductive cases and congenital cases were included and the preva-
lence were recorded as 4.59%, 1.61%, 0.80%, and 0.65% respec-
tively (Table 1).
To investigate the prevalence of cattle diseases at Chittagong divi-
sion of Bangladesh, a total of 2614 clinical cases were diagnosed
in six categories among which the prevalence of digestive disor-
ders (45.14%) and parasitic diseases (30.64%) were significantly
higher (p <0.01). Our results are in agreement with Pallab et al.
(2012) who reported digestive disorders as 47.05% and parasitic
infestation as 26.79% among other diseases in cattle. We found
comparatively lower disease prevalence in local breed (28.46% in
Reg Chittagong and 27.31% in Non-descriptive Deshi) than in
cross-bred cattle (44.23%) which might be due to their natural
resistance to diseases especially under rural production systems
(Bhuiyan 2007, Mannan et al. 2009).
Overall prevalence of infectious diseases among six categories
was 9.49% of which foot and mouth disease was recorded as
4.74%. Sarker et al (2011) reported higher prevalence of foot and
mouth disease (25.07%) in Rajshahi district of Bangladesh. This
variation might be due to different geographical locations and
related environmental factors. In our study the prevalence of mas-
titis was 1.30% which is slightly lower than the report of Rahman
et al (1972) and Pallab et al (2012). The prevalence of infectious
diseases was highest in Cross-bred cattle (5.78%) and lowest in
Non-descriptive Deshi (1.19%). Females were more susceptible to
infectious diseases than male cattle. Our results are in agreement
with the findings of Bhuiyan (2007) and Mannan et al (2009).
In parasitic disease category, fascioliasis was recorded as 10.44%
and among hemoprotozoan parasites, prevalence of babesiosis and
anaplasmosis were 0.80% and 0.19% respectively. Alim et al
(2012) reported the overall prevalence of hemoprotozoan diseases
as 16.18 and 12.02% in crossbred and indigenous cattle, respec-
tively where babesiosis and anaplasmosis were predominant. Is-
lam et al (2014) reported that prevalence of fascioliasis in house
hold and slaughtered goats were 31.75% and 10.10% respectively.
Variations in parasitic disease prevalence might be due to envi-
ronmental factors, animal species and other related factors.
Highest prevalence (45.14%) was recorded in digestive disease
category of which simple indigestion was 15.990% followed by
anorexia (14.07%), ruminal acidosis (12.24%), ruminal alkalosis
(2.83%). The prevalence of digestive disorders in our study was
slightly lower than the report by Pallab et al (2012) and higher
than the report by Rahman et al (1972) and Kabir et al (2010). In
Bangladesh, most farmers are rearing cattle for fattening purpose
and they are trying to feed their cattle excessively to make their
cattle fatten within short period which might be the cause of high-
est prevalence of digestive disorders.
Overall prevalence of metabolic diseases (3.18%) in our study was
lower than the report by Pallab et al (2012) who reported metabol-
4 International Journal of Biological Research
ic disease prevalence as 4.24%. Among the metabolic diseases,
prevalence of milk fever was comparatively high which might be
due to deficiency of calcium at the time of early lactation period.
The prevalence of respiratory diseases was recorded as 3.90%
which was lower than the report by Pallab et al (2012) who report-
ed 6.20% prevalence.
According to our study, major diseases of cattle in Chittagong
district of Bangladesh include digestive disorder, parasitic disease,
infectious disease, respiratory disease and metabolic disease of
which digestive disorders and parasitic diseases are predominantly
prevalent diseases. Cross-bred female cattle are highly susceptible
to most of the diseases. Our large set of data on cattle disease
prevalence in Chittagong district of Bangladesh provides valuable
insight to design and implement priority based research on specif-
ic disease and to take efficient control strategies against the dis-
