This experiment was conducted to evaluate the effects of dietary supplementation of aloe vera extract (w/v) on growth performance of broiler. The present study explored the potentials of medicinal plants Aloe barbedensis mixture in broiler performance. For this purpose, 120 day old chicks were randomly assigned into five treatment groups, namely T 0 , T 1 , T 2 , T 3 and T 4 . Each treatment group contained 24 chicks. The chicks were purchased from a local chick hatchery named Nourish Poultry & Hatchery Ltd. Birds were brooded up to 10 days and then reared in separate flock for 35 days in an open sided house. Each treatment group was further replicated into three sub-groups and each contained eight birds. Experimental birds in T 1 , T 2 , T 3 and T 4 were provided with aloe vera extract (w/v) @ 05, 10, 15 and 20 ml per liter of drinking water while T 0 was maintained as control group. Relevant data were recorded throughout the experimental period and subjected to statistical analysis. The data on growth parameters (body weight gain, feed consumption, feed efficiency, water intake) and feed cost and gross return per broiler were evaluated. The results of the study revealed that the aloe vera supplemented groups showed higher live weight gain than untreated group. Aloe vera supplemented groups showed more live weight gain in the terminal stages of the experiment. Aloe vera (w/v) extract supplemented groups performed the best feed efficiency. The live weight gain and feed efficiency were significantly (P<0.05) better in the broilers provided water containing 15 ml/L aloe vera aqueous extract. Water intake, feed intake and abdominal fat deposition of broilers given aloe extract in drinking water were not different among each other. So, 15 ml/L aloe vera aqueous extract may be given to the broilers drinking water.

This research work was conducted to detect the prevalence of Infectious Laryngotracheitis (ILT) Virus-specific antibody in chickens from Gazipur district in Bangladesh at Department of Microbiology, Hajee Mohammad Danesh Science & Technology University, Dinajpur and Poultry Care Lab, Garzipur from January to June 2012. A total number of 232 sera sample of commercial layer chicken were collected from 17 different commercial layer farms at different ages. The layers prognosed for sampling had not been previously vaccinated against ILTV. The indirect enzyme linked immunosorbent assay (iELISA) was performed to estimate the Infectious Laryngotracheitis (ILT) Virus-specific antibody. Out of 232 samples, 189 (81.47%) samples were found to positive for Infectious Laryngotracheitis (ILT) Virus-specific antibody. In 17 different commercial farms prevalence based on age were 75%, 87.5%, 87.5%, 90%, 81.25%, 80%, 100%, 70%, 81.25%, 81.25%, 90%, 93.08%, 87.5%, 75%, 75%, 68.75% and 75% in the age limit 08, 09, 11, 12, 13, 14, 15, 16, 17, 17, 19, 21, 25, 31, 35, 44 and 51 weeks respectively and farms showed high level of ILT virus specific antibodies (IgG). This result showed that in 15 weeks of age prevalence was highest position i.e; 100%. The result of this study indicate that there were a high prevalence of Infectious Laryngotracheitis (ILT) Virus circulating at Gazipur district in Bangladesh.Asian J. Med. Biol. Res.

Bangladesh first experienced outbreaks of highly pathogenic avian influenza (HPAI) subtype H5N1 in poultry 2007 and by December 2012 a total of five hundred fifty six (556) outbreaks have been reported of which four hundred ninety nine (499) outbreaks occur in commercial poultry farm as against only fifty seven (57) in backyard poultry chicken. The virus appeared to be a deadly pathogen causing a total of six hundred eight (608) human cases with three hundred fifty nine (359) deaths in the world. In Bangladesh seven (7) human cases have been reported with a singular mortality of a child acquiring the infection from household poultry. There had been six epidemic waves of AI outbreaks in Bangladesh since March 2007 and other new waves seem to have started. From the six year’s incidence analysis it was found that higher number of outbreaks occurred in the month of February followed by March. The outbreak started from the middle to late winter and continued up to summer. The phylogenetic analysis of viruses isolated till 2010 revealed only one clade 2.2 virus circulating in Bangladesh. But from 2011 two new clades 2.3.2 and 2.3.4 viruses have been introduced. In 2012, it was observed that Clade 2.2 viruses that was in circulation since 2007 were replaced by 2.3.2.1 viruses. Extensive backyard poultry including a large number of ducks, dense human population, and economic dependence of poor people on poultry with low awareness about risk of infection, live bird trading and poor bio-security were critical factors in the spread of avian influenza infection that posses key challenge in rapid containment. Because of the complex situation in poultry production and marketing system, attempts to control this disease through stamping out and bio-security measures have apparently failed in Bangladesh.Bangladesh J. of Livestock Res. 19(1-2): 44-49, Jan-Dec 2012

The present study was conducted to know about the management of gid disease of goat at Upazila Veterinary Hospital, Rangpur Sadar and District Veterinary Hospital from July, 2011 to December, 2011 in Rangpur district at field level. A total of 12 goats were diagnosed based on history and presenting clinical sings. Furthermore, surgery was performed -in five cases. Circling movement, keeping the head downward to the affected side were major clinical sings. In all the cases, a half moon shaped incision was given at the operative site and after trephining the skull, the cyst was removed. The disease was predominant in female (91.66%) than male (16.66%). Among female goats, the prevalence of gid in pregnant and non-pregnant were 36.36% and 63.63% respectively. Black Bengal goats were more susceptible (91.66%) to this disease. The method of operation is considered to be useful as treatment in the field level. Alternative way of treatment using anthelmintics or other drugs have studied.
