TL;DR: The length-weight relationship is very important for proper exploitation and management of the population of fish species and is also very much essential for stabilizing the taxonomic characters of the species.
Abstract: The length-weight relationship is very important for proper exploitation and management of the population of fish species. To obtain the relationship between total length and other body weight are also very much essential for stabilizing the taxonomic characters of the species. Among the freshwater fishes, length-weight relationship of different fishes has been done by many researchers, viz., Tilapia mosambica (Dhoa & Dewan, 1967), Puntius stigma (Islam & Hossain, 1991-92), Alia coila (Alam et al., 1994), Chanda nama and Chanda ranga (Iqbal et al., 199596), Botia lohachata (Mortuza & Mokarrama 2000), Rhinomugil corsula (Mortuza & Tawfeequa, 2006).

TL;DR: All the spices were effective as protectants of black gram seeds, however, clove and black pepper were most effective.
Abstract: The experiment was conducted to investigate the insecticidal potency of some spices eg. clove ( Syzygium aromaticum ), black pepper ( Piper nigrum ), ceylon cinnamon ( Cinnamomum zeylanicum ), black cardamom ( Amomum subulatum ), nutmeg ( Myristica fragnans ), black cumin ( Nigella sativa ), turmeric ( Curcuma longa ), red pepper ( Capsicum frutescens ), cumin ( Cuminum cyminum ), green cardamom ( Elettaria cardamomum ) and bay leaf ( Cinnamomum tamala ), against the pulse beetle, Callosobruchus maculatus (F.) on stored black gram ( Phaseolus bengalensis L.). Data were recorded on days to 100% mortality; number of adults emerged and weight loss (%) of black gram. All the spices were effective as protectants of black gram seeds. However, clove and black pepper were most effective. Key words: Callosobruchus maculatus , stored black gram, mortality, adult emerge, extent of damage. doi:10.3329/ujzru.v27i0.1953 Univ. j. zool.

TL;DR: In the contact bioassay eucalyptus oil was found to be the most effective in inducing mortality both after 24 and 48 h of treatments, and the efficacy in respect of the toxicity followed in the order: clove > cinnamon > cardamom > neem > eucallyptus after 24 h after treatment.
Abstract: Toxicity of five essential oils (EOs), viz. cardamom, cinnamon, clove, eucalyptus and neem oils were investigated against the cowpea weevil, Callosobruchus maculates (Fab.) adults, through contact and fumigation bioassay. In the contact bioassay eucalyptus oil was found to be the most effective in inducing mortality both after 24 and 48 h of treatments. The toxicity of the oils followed in the order: eucalyptus > clove > cinnamon > cardamom > neem. In the fumigation bioassay, however, a reverse result was obtained with eucalyptus oil where it shows the last position for 24 h and fourth position for 48 h after treatments. The efficacy in respect of the toxicity followed in the order: clove > cinnamon > cardamom > neem > eucalyptus after 24 h after treatment, and clove > cinnamon > cardamom > eucalyptus > neem after 48 h after treatments.

TL;DR: It was concluded that the reproductive performance like early maturity, larger litter size, shorter postpartum period, minimum kidding interval are better in Black Bengal goat, while productive performance like higher birth weight, maximum body weight gain, high milk yield, longer lactation length are suitable in crossbred goat.
Abstract: The present investigation was carried out to detect the status of different productive and reproductive parameters of Black Bengal and Crossbred goats at Bandaikhara village under Atrai Upazilla of Naogaon district during the period of September to December/2005. The average age at first sign of heat of Black Bengal goats was better than that of Crossbred goats. In Black Bengal goat the average age at first kidding was 360.5±10 days, whereas, in crossbred goats it was 411.5±15.5 day. Significantly (P<0.01) lower the post partum heat period in Black Bengal goat than the crossbred goat. The average kidding interval in Black Bengal and Crossbred goats were 179±20 and 270±22 days respectively and differences are statistically significant (P<0.01). The usual numbers of kids at one time in Black Bengal goats vary from single to quadruplet. On the other hand, litter size of crossbred goat was single or twin. The average birth weight of Black Bengal goat was lower than Crossbred goats, which are statistically significant (P<0.05). The average body weight gain after 365 days is better in Crossbred than Black Bengal goats and statistically significant (P<0.01). The average milk yield in Crossbred goat was 1.05 liter/day, whereas, in Black Bengal goat, it produces milk that only nourished its kids. It was concluded that the reproductive performance like early maturity, larger litter size, shorter postpartum period, minimum kidding interval are better in Black Bengal goat. On the other hand productive performance like higher birth weight, maximum body weight gain, high milk yield, longer lactation length are suitable in crossbred goat.

TL;DR: The proportional prevalence of different disease conditions in cattle was much higher in Hariana breed than those of local and crossbred cattle and in male in case of cattle and goats.
Abstract: A study was conducted to investigate about the prevalence of parasitic diseases in different abattoirs in selective area of Bangladesh such as Comilla and Brahmon Baria districts. Animals were examined for post-mortem defects in different abattoirs of those districts. The study started from February, 2008 to August, 2008. The total examined animals were 3510, among them 1460 cattle, 620 buffaloes, 970 goats and 460 sheep. Age, sex and breed of the examined animals were recorded as far as practicable. The overall prevalence of hydatidosis was highest (26.01%) followed by fascioliasis (20.74%), amphistomiasis (19.62%). The prevalence of above mentioned diseases was higher in older animals. The prevalence of hydatidosis, fascioliasis and amphistomiasis was higher in male in case of cattle and goats. But the prevalence of those diseases was distinctly higher in female animals in case of buffaloes and sheep. The proportional prevalence of different disease conditions in cattle was much higher in Hariana breed than those of local and crossbred cattle.
