Publisher: 2006Dissertation note: A study was conducted to understand the impact of community based animal health services delivery systems on epidemiological parameters and farmer's economic sustainability in Central Punjab. In Pakistan three systems for the animal health services delivery are being practiced without any data base and conclusive findings for the comparison purposes and in terms of the replication if needed in future, therefore, a study was planned to quantify and compare the three systems. These systems are; community based, public based and conventional based animal health services delivery systems. As the community based system was launched as Halla scheme, in Central Punjab through the German Technical Cooperation program / funding. Therefore, the other two systems i.e. public and conventional based were selected in the areas adjacent to the community based system (Halla Cluster). The project area was selected because of the similar geographical, environmental, socio cultural and political similarities. One cluster of five villages was selected randomly for each system. The data was obtained from each cluster through active disease surveillance and was recorded on a questionnaire. Each questionnaire was used for one farmer. The cluster of five villages was 'considered as one herd. In the 1st project, the clusters were quantified and compared on different parameters, like provision of animal health services, provided from the system to the member farmers. Epidemiological parameters like morbidity and mortality rate were recorded and analyzed statistically. In the 2IId project, the community trials were also conducted to compare the efficacy of prophylactic interventions, for the economically important diseases of buffaloes and cattle i.e. the haemorrhagic septicaemia and foot and mouth disease. The effect of deworming was also recorded with reference to morbidity and mortality. In the third project the sustainability of the farmers residing in the systems were compared in terms of cost benefit ratio. Animal health services were arranged like vaccination, treatment, deworming, artificial insemination and nutrition support. Poor, good and better services were provided in conventional based, community based and public based animal health services delivery systems, respectively. The impact of services on morbidity and mortality was recorded, the minimum morbidity and mortality rate was recorded in the community based system and moderate and maximum morbidity rate, mortality rate, number of outbreaks and fertility rate due to various diseases were recorded in the conventional based animal health service delivery system. The results were statistically analyzed and significant difference at a level 5% was estimated. The efficacy of the vaccination was estimated and it was statistically found that the morbidity and mortality rates were significantly low in the intervention herds of buffaloes and cattle, as compared to non intervention herds. The overall sustainability of the farmer in term of cost benefit ratio was higher in community based as compared to public based and conventional based animal health services delivery system. In conclusion the better the animal health services delivery system, the more prosperous was the farmer. So, it is recommended that the community based animal health service system be promoted and replicated on priority basis. The animal health services are provided by public based service deliverers but they are not of the same quality as were provided by the community based system in Halla Cluster. This is the reason that in spite of all the services provided by the public based system, the morbidity rate and mortality rate due to various infectious and non infectious diseases were higher in buffaloes and cattle as compared to the community based system. In conventional based system neither the community based services nor the public based services were available for the farmers because those areas were remote and far from the public veterinary hospitals. Therefore, the morbidity rate and mortality rate at the highest spectrum of ranking and disease burden/disease load. The magnitude of disease problems was highest in the conventional based, lowest in the community based system and intermediate in the public based system. Better the quality of services are provided the minimal are the losses due to the diseases in the animal populations and in turn better the cost benefit ratio and ultimately the more prosperous is the farmer. The only way of poverty alleviation in the rural communities is to replicate the community based animal health services delivery system (Halla) with certain modifications in the Provinces of Punjab and Sindh in particular and in North West Frontier Province and Balochistan in general

Publisher: 2011Dissertation note: Anaplasmosis is globally distributed tick-borne disease of livestock with great
economic importance in cattle industry. The current project was designed to estimate the
prevalence of anaplasmosis, ticks and risk factors associated with seroprevalence of
Anaplasma marginale among cattle in Sargodha, Khushab and Rawalpindi districts,
Punjab, Pakistan. Moreover, haematological changes in A. marginale infected cattle and
efficacy of chemosterilization regimens were evaluated using locally available drugs for
the elimination of adult naturally infected carrier cattle.
A total of 1050 blood, serum and tick specimens were collected from randomly
selected small holders (n=90) and private livestock farms (n= 12) using multistage cluster
random sampling technique. A total of 30 union councils, 34 cattle farms (30 small
holders and 4 livestock farms) and 350 cattle were selected as primary, secondary and
elementary sampling units from each district. Sampling unit was indigenous and
crossbred cattle of both the sexes.
Microscopic examination of the Giemsa stained blood mears revealed an overall
prevalence of blood parasites as 21.14%. Anaplasma marginale was the highe t prevalent
(5.81 %) haernoparasite of cattle followed in order by Theileria sp. (5.14%) and Babesia
bigemina (4.76%), respectively. Crossbred cattle were more susceptible to TBDs as
compared to the indigenous cattle. Highest prevalence of TBDs was recorded in summer.
The prevalence of tick-transmitted diseases was higher in small holders (31.3%) than
private livestock farms (17.5%). Chi square analysis indicated a significant association
(P<0.05) among indigenous and crossbred cattle to selected TBDs. Wherea. non-
significant association between different age groups, seasons, sex and farm sizes were
revealed.
The overall seroprevalence of Anaplasma marginale in cattle using cELlSA was
31.05%. Seroprevalence was higher in crossbred cattle of more than 4 years of age and
there was a significant (P<O.OO I) association between different age groups and breed. The
seroprevalence was significantly (P<0.05) higher in summer season in Sargodha and
Khushab districts. Moreover, the seroprevalence was significantly higher in small holders
in all study districts.
The epidemiological data and relevant information regarding area, host and farm
management factors were collected on a questionnaire through interview from each dairy
farmer, attendant or manager from September, 2009 to August, 20 10. Multivariate
analysis of risk factors revealed that cattle of more than 4 year of age (OR=5.42), heavy
tick infested (OR =2.10), crossbred (OR = 1.59) cattle were significantly at higher risk for
seroprevalence to Anaplasma marginale. Presence of Rhipicephalus (Boophilus)
microplus (OR=3.70), use of ivermectin (OR=3.97), moderate interval of acaricide
frequency (OR= 16.50), stall feeding (OR=4.90) and use of unhygienic needles
(OR=24.00) were significantly associated with seroprevalence to Anaplasma marginale
in cattle (P<0.05). The Sargodha district was at higher risk (OR = 1.81) as compared to
Khushab and Rawalpindi.
The tick species identified from cattle were Hyalomma anatolicum anatolicum,
Rhipicephalus (Boophilus) microplus, Rhipicephalus sanguine us, Rhipicephalus
(Boophilus) annulatus and Haemaphysalis sp. The overall prevalence of tick infestation
among cattle was 54.76%. The highest prevalence (57.71%) of cattle tick infestation was tick infested sites in cattle followed by dewlap (92%), inner thighs (90%), neck & back (54%), tail (26%), ears (13%), around eyes (10%), flanks (4%) and legs (2%).
The haematological changes were studied at different levels of parasitaemia " 7%, >7-15% and> 15%) in Anaplasma marginale infected Sahiwal and crossbred cattle. There was a significant difference (P<O.OS) among total erythrocyte count (TEC), total leukocyte count (TLC), haemoglobin (Hb), packed cell volume (PCV), mean corpuscular
haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC) at different levels of rickettsemia in both breeds. ignificant difference (P<O.OS) was noticed among RBCs, PCV and MCH blood parameters between Sahiwal and crossbred cattle.
A total of sixty Anaplasma marginale seropositive adult Sahiwal cattle were selected having their ages between 3-4 years ranging in weight from 246-341 kg. The animals were divided in four groups designated as OXY -group-I, E RO-group-II, IMC- group-III and control-group-IV, comprising IS animals each. The seropositive animals received oxytetracycline (22 mglkg IV once in a day for five days), enrofloxacin (S mglkg IV once in a day for five days) or imidocarb (S mglkg 1M twice, 7 days apart). Re ult of chemosterilization study indicated that oxytetracycline 13/1S (86.67%) and irnidocarb
dipropionate II/IS (73.33%) eliminated Anaplasma marginale infection in adult naturally infected carrier cattle on S6th day. The carrier clearance was confirmed by cELISA followed by subinoculation of blood in seronegative splenectomized calves.
It was concluded that TTBDs are widely distributed in Punjab, Pakistan. Host. management and area factors are involved with the seroprevalence of Anaplasma marginale in cattle. Haemolytic anaemia is the major haematological finding of Anaplasma marginale in cattle. Oxytetracycline is more effective and safe In chemosterilization of persistent Anaplasma marginale infection in cattle. There is a need for country wide epidemiological studies on ticks and TBDs using advanced serological
and molecular techniques. Moreover, the identification of the potential vector of anaplasmosis should be required for the effective prevention and control of anaplasmosis in Pakistan.
