Haemorrhagic Septicaemia was recognized as the most foremost killer disease among cattle
and buffaloes in Sri Lanka for almost five decades since its detection in mid nineteen fifties. A retrospective
study was carried out to analyze the occurrence pattern describing the epidemiological features and major
control measures applied in the country during a period of fifteen years since 1996. The last clinical case was
detected at Millaniya in Kalutara district in 2004. Nonexistence of the disease in its clinical form has
diminished the prophylactic vaccination since 2009.

Dairy production plays a vital role, as a source of income generation and a nutrient supplier to
farm families in Badulla district. Badulla veterinary range covers an area of 52.5 sq.Km land and cattle are
the leading livestock commodity. The main objective of the present study was to identify and characterize
the two main small holder dairy farming systems, Village Based System (VBS) and the Estate Based System
(EBS) in Badulla district. A survey was planned and carried out in Badulla district from February to April
2010. Forty farms from each system were randomly selected and the farmers were interviewed using a
structured questionnaire. Two sample ‘t’ test was used to analyze the data collected.
Herd size of VBS was higher (p<0.05) compared to EBS because of the bulls kept by the VBS farmers
for draught purpose. No significant difference was observed between the VBS (80.35%) and EBS (85.86%)
on cost of feeding as a percentage of total cost of production. Though the price of compounded cattle feed
was less than that of coconut poonac price, farmers of both systems did not adopt cattle compounded feed.
Family labor was the principle source of labor in cattle farming in the area. Both farming systems have
positive impact on both milk and total revenue from dairy farming. Although total income per cow unit did
not show significant variation (p>0.05) between systems (Rs. 6528 vs. Rs. 6697 for VBS and EBS
respectively), the average milk production was higher in EBS compared to VBS (Rs. 9.25/ L/ CU/ d vs.
Rs.7.13/ L/ CU/ d). Sale of milk at the informal market in both systems seems to be poorly organized. As in
other areas of Badulla district, organized milk collection through Milk Industries of Lanka Company
Limited (MILCO) was not observed in the study area. Therefore, price of milk varied from Rs. 22 to 40 per
liter in the informal market. Majority of farmers did not utilize manure properly, but only few farmers used
it as a source of income. The profit margin did not differ much between two systems and a mean value of Rs.
5415 vs. Rs. 5586 for VBS and EBS respectively was observed. The constraints identified were similar for
both systems and the poor farm gate price for milk was the major constraint identified in this survey.
However, long term sustainability and profitability of these systems depend largely on management and
production efficiencies of systems. Therefore, research and technology transfer should be targeted on the
needs of dairy farmers in the particular farming system.

SUMMARY: Coccidiosis is caused by a protozoan parasite of genus Eimeria, commonly known as coccidia. Eimeria infection in goats was studied in Kandy and Nuwara Eliya districts in the Wet Zone of Sri Lanka for a period of 11 months from May 2006 to March 2007. Fresh faecal samples were collected and a clean separation of oocysts for morphological examination was obtained using a modified salt floatation and sedimentation technique. A total of 95 goats were sampled. The overall prevalence of coccidia was 46.1%, with Kandy district recording a significantly higher prevalence (58.9%) than Nuwara Eliya district (36.5%; c2 = 4.33, p < 0.05). Intensity of infection in the Wet Zone was low, having few high positive cases only in the goats at Padiyapallela (5.8%), Uda Peradeniya (2.3%) and Pilimathalawa (12.5%). Morphological identification of live parasites revealed eight species of Eimeria belonging to Family Eimeriidea namely, E. arloingi, E. ninakohlyakimovae, E. jolchijevi, E. caprina, E. christenseni, E. hirci, E . aspheronica and E. alijevi. Five of them were reported from Nuwara Eliya district while all eight were found in Kandy district. Mixed infections with two or more Eimeria species were common. Of the eight species recorded in this study, E. caprina presents a new record for goats Sri Lanka. This species was found only in Kandy district from a farm at Uda Peradeniya. Kids were more affected than the adults. Kids aged less than six months had 83.3% infection followed by 15.0 % infection in those aged six to 12 months. Extremely low prevalence of infection among goats aged more than 12 months (1.7%) could be because they are known to develop strong immunity with increasing age. Anti-coccidial treatment was a critical factor determining the prevalence of disease more than the management practices.
