The study was conducted at Upazila Livestock Development Centre, Kapasia, Gazipur, during July, 2011 to December, 2011 to identify and determine the prevalence of clinical diseases and disorders of goats. A total number of 488 clinical cases of goats were recorded. Diagnosis of the clinical cases of goats were based on general examination (history and owner’s complaint), physical examination of patient (inspection, palpation and percussion), clinical examination, microscopic examination and using common laboratory techniques. The clinical cases were divided into three groups on the basis of treatment required-medicinal, gynaeco-obstetrical and surgical cases. Among the three types of cases, medicinal cases 428(87.72%) were highest followed surgical cases 43(8.80%) and gynaeco-obstetrical cases 17(3.48%). Among the medicinal cases of goats, the contagious diseases PPR 32(6.56%), black quarter 23(4.73%) fascioliasis 77(15.78%), diarrhoea 35(7.17%), dysentery 30(6.15%), ectoparasitism 30(6.15%), paramphistomiasis 25(5.12%), gastrointestinal nematodiasis 21(4.3%), fever 20(4.1%) were recorded major disease problems in goats. Among the gynaeco-obstetrical cases, retained placenta 5(1.02%) and repeat breeding 12(2.46 %) were recorded as major gynaeco-obstetrical problems in goats. Abscess 9(1.84 %), castration 4(0.81%), myiasis 10(2.05%), navel-ill 7(1.43%), gid disease 2(0.41%), urolithiasis 5(1.02%) and fracture 6(1.23%) were recognized as the main disorders which required surgical interventions. It may conclude that a number of diseases have been occurring in goats at study area and this report may help to develop strategies against major diseases reported in this study.Asian J. Med. Biol.

This study evaluated the effect of ginger on the growth performance, carcass quality of broiler chickens. 20 broiler chickens were randomly selected into two treatment groups identified as T1 and T2 with a positive control and a negative control group. Each treatment contained with five birds. Birds on T1 were treated with 1% ginger extract and T2 was treated with 2% ginger extract via drinking water. Significant variations (p<0.05) existed between the control and other treatments in mean final body weight, dressed weight, daily feed intake and feed conversion ratio. At the end of experiment (35 th day) for 1% ginger extraction treatment the live body weight is 1746gm (p<0.05), dressing weight 1106.4 (p<0.05) and FCR is 1.67(p<0.05). The usage of the test ingredients had a significant effect (p<0.05) on dressing percentage. Supplementation of ginger improves the performance of broilers when added at the rate of 1% of broiler ration and can be a possible alternative to antibiotic growth promoter in the feeding of broiler chicken.

There is a serious public health concern of the use of antibiotics sub-therapeutically and/or as growth promoter in poultry feed and water. Therefore, there is an urgent need for alternatives. Moringa oleifera is a phytobiotic, which has been reported to possess antimicrobial and immuno-modulatory properties. This study aimed to investigate the effects of aqueous M. oleifera leaf extract (MOLE) supplementation on growth performance and hematological indices of broiler chickens. The 36 day-old broiler chicks (Cobb 500) were randomly divided into three dietary groups (group A, B and C) having 12 birds in each. The group A was considered as negative control which had received the basal diet and fresh drinking water. The group B was fed with basal diet and antibiotics (Ciprofloxacin) plus Vitamin B-complex mixed drinking water(Positive control). The group C was fed with basal diet and drinking water supplemented with 1% MOLE. Body weight, feed intake and feed conversion ratios of the birds were recorded on weekly basis. On day 35th of the feeding trail, blood samples from five birds per replicate were used for the study of hematological indices. Birds under Group C attained intermediate body weight (1892 g) and best FCR (1.48) those were comparable with that of Group B but better (p<0.05) than those of Group A. There was a trend of decrease (p>0.05) internal organs weight in Group C compared to other groups. However, zero mortality rate and similar hematological indices were observed in the birds across the treatments. Here, the results suggested that, the aqueous MOLE can be included in the drinking water of broiler chicken for reduced feed intake and improved feed conversion efficiency and it can be considered as an alternate to synthetic antibiotics as growth promoter to fight the emergence of antibiotic resistance phenomena in poultry industry.J.

Background and Aim: Global trend to remove the antibiotic growth promoter (AGP) from animals contributes to the exploration of successful measures to sustain production and reduces the intestinal diseases in the post-AGP era. Plant extracts, therefore, have been used to improve performance and intestinal health. Here, we conducted a study to evaluate the effects of neem (Azadirachta indica) leaf extracts (NLE) as alternatives to AGPs in broiler chickens. Materials and Methods: Sixty day-old broiler chicks were assigned to 12-floor pens, each stocked with five birds and divided into three treatment groups of four pens per treatment. The groups were: Negative control, basal diet without additives; positive control, basal diet with antibiotics and vitamins; and NLE treated group, basal diet supplemented with 0.1% aqua extract of neem leaves. Results: Overall feed intake was significantly (p≤0.05) highest in the positive control. Higher body weight, higher dressing percentage, and lower feed conversion ratio were observed in birds treated with NLE compared to the negative control group (p≤0.05) but not the positive control group (p>0.05). There was no significant variation in hematology between different groups. Furthermore, the economic evaluation indicated that the NLE treatment was found cheaper than control and antibiotic treatment in cost-benefit analysis. Conclusion: We suggest NLE might be a cheaper alternative to antibiotics in broiler production as indicated by improved body weight and feed efficiency.
