Abstract

The Black-necked Cranes arrive in Arunachal Pradesh during winter months to keep away from cold climate of Tibet. They have been reported in the past from Gandhi gram and Apatani plateau areas of the State but at present they are restricted to Santhi valley and Zemithang areas only. The present paper is a study on its range, status and behaviour in Arunachal Pradesh.

Abstract

The ethanolic extract (D002) of the Phlebophyllum kunthianum (whole plant) was tested in vitro against Giardia lamblia and has been found to exhibit 100% antigiardial activity at the dose of 125 μg/ml. On bioassay guided fractionation of D002 by using the solvents of different polarity, n-butanol (F005) and aqueous fraction (F006) have been exhibited 100% antigiardial activity at the dose of 500 μg/ml and 250 μg/ml respectively. Fraction F011 prepared from F006 was found to be most active comparable to the D002 and exhibited 100% antigiardial activity at the dose of 125 μg/ml and number of live trophozoits of 13.48±0.97 at the MIC value of 62.5 μg/ml.

Abstract

The following five new species of benthic foraminifera are described and illustrated from the Neogene sequence of Little Andaman Island, Bay of Bengal: Bulimina andamanica* , Cibicides hochstetteri* , Pararotalia geei, Fursenkoina indica, Ehrenhergina schwageri. Observed stratigraphic ranges are given for each species. All the new species described occur associated with deepwater assemblages characteristic of lower to middle bathyal depths. Those marked with an asterisk have proved useful, as zonal markers in the Andaman Sea region.

Abstract

The experiment was conducted on 18 buffalo calves of about 1-3 months of age to find effects of three different calf starters (differing on the source of protein) on the behavioural response and cost of rearing. The calves were divided into three groups (six calves in each group) randomly under three treatments i.e. T₁, T₂ and T₃. In T₁ group groundnut cake, T₂ group soyabean and in T₃ group mustard cake with fish meal (10 %) as protein source, respectively with green fodder and bhusa was fed ad lib. Average eating time spent during day time by the calves were 215.53 ± 8.703, 213.16 ± 9.841 and 182.03 ± 10.318 minutes and the corresponding figures for rumination and resting time spent during day time were 130.07 ± 5.397, 168.17 ± 6.742 and 152.0 ± 11.475 minutes and 280.57 ± 14.988, 274.77 ± 18.566 and 226.03 ± 18.540 minutes in T₁, T₂ and T₃ groups, respectively revealed that feeding behaviour was significantly influenced by the treatments. The eating time was significantly (P<0.05) low in T₃ as compared to T₁ and T₂. However, there was no significant difference between T₁ and T₂. The rumination time was significantly (P<0.05) higher in T₂ as compared to T₃. The rearing cost per kg body weight gain was Rs. 33.86, 26.91 and 32.56 in T₁, T₂ and T₃, respectively. The cost per kg body weight gain was less in T₂ followed by T₁ and T₃.
