- Effects of feeding probiotic on daily gain, fecal characteristics and
blood metabolites in calf
Authors: S M Amanullah, R Jahan, M M Rahman, M A Samad, S M J Hossain
Pages: 45 - 54
Abstract: Feed substrate containing probiotic culture of Lactobacillus acidophilus, Bacillus subtilis and Sacharomyces cerevicae were prepared for feeding calves. Twelve 2 weeks old calves were distributed equally in two groups (6 calves in each) and supplemented with (treated) or without probiotic feed (Control). Calves were reared in an individual pan and provided with ad libitum suckling, calf starter, and soft green grass. In 90 days trial period data were collected on growth performance, blood metabolic profile, immune status, fecal microbial load, morbidity etc. It was observed that milk intake, dry matter intake (DMI), daily gain and feed conversion ratio (FCR) were not differed (P>0.05) between treatments. Claves under the probiotic fed group voided feces of better physical properties (color, odor and consistency) compared to the control. Weekly E. coli count (log10CFU/g) in feces was found lower (P<0.01) in the probiotic group compared to the control. The plasma IgG (ng/ml) concentration was found higher (P<0.05) in probiotic group than in the control, and total cholesterol level tended to be high (P=0.071) in the same group. It is concluded that, probiotic feed improved fecal characteristics, lesser E. coli load in feces, lowered diarrheal incidence and improved immunoglobulin status of calves from 15th to 105th days of age.

- Performances of Red Chittagong cow under farming and rural conditions
Authors: M A Hossain, M E Haque, M Tanzin, M R Islam
Pages: 55 - 60
Abstract: This study aimed to assess the hematological parameters, productive and reproductive performances of Red Chittagong cows (RCC) under farming and rural production systems. Hence, three villages (Sailabari, Munsumi and Baniagati) of Khokshabari union under Sadar upazila of Sirajganj district were selected. The 40 Red Chittagong cows from each production system were taken under this study. Twenty (20) farmers were selected through direct interviewing process with a structured questionnaire. Farming condition and rural condition data were analyzed with unpaired t-test along with GLM procedure of SAS statistical package. Services per conception (times), postpartum heat period (days) and calving interval (days) had significant (p<0.01) differences between farming and rural condition, whereas, age at first calving (months) significantly differed (p<0.05). Average milk yield (kg/d) had significantly different at the values of p<0.05, whereas, lactation period was significantly differed at the values of p<0.01. Hemoglobin (g /100ml) and PCV% were significantly different (p<0.05) between farming and rural condition of RCC in the selected areas. From the study, it may be concluded that the productive and reproductive performances of RCC were better in farming condition than in rural conditions in selected areas.
