| dc.description | The economy of Bangladesh is mainly based on Agriculture. Our agriculture
primarily depends on Livestock. Livestock is considered as the backbone of
agriculture (Ahmed, 2000). In Bangladesh agricultural activities centre around
crop cultivation which accounts for over two-thirds of agricultural value added.
Another 15% of the value added originates from livestock and poultry rearing,
which are activities supplementary to crop husbandry, carried out by using
homestead land and surplus family labor of farm workers (Khan et al. 2004).
Livestock provides new raw material for industry, serves a social security for the
rural poor, and provides security against crop failure or damage during draught or
cyclone. The contribution of the livestock sub-sector to GDP at constant prices
was 1.84% in the fiscal year 2012-13 (BER, 2014). Cattle among other livestock
species available are the most versatile component in relation to existing
integrated agricultural farming system in Bangladesh. Tropical, agro-based
Bangladesh has 53.21 million livestock of which 23.34 million are cattle (BER,
2014). Cattle are the main source of animal protein as they provide meat, milk and
source of draft power and hides. From cattle, Bangladesh gets 173 thousand
metric tons beef and 782 thousands metric tons milk per year. Further, the country
gets 18 thousand metric tons butter and ghee and 32 thousand metric tons
excellent type of hides from cattle (BBS, 2001). Bangladesh earns 3% foreign
money by exporting leather and leather goods (EPB, 2011). | en_US |
| dc.description.abstract | Ticks are economically the most important ectoparasite of cattle and other
domestic species in tropical and subtropical countries including Bangladesh. The
present experiment was carried out to investigate the comparative efficacy of
neem (Azadirachta indica) leaves extract (15% as spray) and ivermectin (1% as
S/C injection) against tick infestation, their effects on some clinical and
hematological parameters in calves. For this purpose a total of 15 calves were
examined for the presence of ticks by physical examination and were divided into
three equal groups as, Group A (infected control group), Group B (treated with
neem) and Group C (treated with ivermectin). After spray of neem leaves extract
and injection of ivermectin the treated and control groups were kept for 28 days
and clinical and hematological parameters were investigated at 7 days intervals.
On the basis of tick count, the efficacy of ivermectin was found 100% on day 7,
14, 21 and 28 after the treatment whereas neem leaves extract (spray) was 68.8%
effective at day 28 against tick infestation in calves. The results showed that the
body weight of calves increased after treatment in groups B and C respectively,
but in control group body weight decreased. Compared to infected control groups,
the feeding efficiency increased in all treated group. There was significant
increase in hemoglobin concentration (Hb), packed cell volume (PCV%), and
total erythrocyte count (TEC) and significant decrease in Erythrocyte
sedimentation rate (ESR) in the neem and ivermectin treated group. All the calves
after neem spray and ivermectin injection remained healthy and no adverse effect
were observed. Appetite increased, and growth and coat color improved rapidly.
Collectively the results suggest that neem leaves extract may be used as an
alternative approach to treat tick infestation where conventional producers are not
available or contraindicated. | en_US |
