Not AvailableAssam Hill goat (AHG) is an important goat germplasm found in Assam and its adjoining areas of India. The study was designed with an objective to study the semen characteristics and freezability of AHG buck semen using Tris -Egg yolkCitrate-Fructose diluent. The mean values of fresh semen characteristics in AHG bucks viz., ejaculate volume (ml), initial sperm motility (%), sperm concentration (x106/ml), live sperm (%), sperm abnormality (%), HOST-reacted sperm (%) andintact acrosome (%) recorded were 0.39 ± 0.01, 77.97 ± 0.73, 3201.00 ± 143.78, 83.02 ± 0.65, 7.66 ± 0.73, 66.95 ± 0.74 and 93.34 ± 0.51, respectively. Mean values for post-thaw semen characteristics i.e., sperm motility (%), live sperm (%),HOST-reacted sperm (%) and intact acrosome (%) were 55.39 ± 0.97, 71.01 ± 0.78, 54.77 ± 0.55 and 82.16 ± 0.43, respectively. It can be concluded that AHG bucks donate acceptable quality of semen which can be frozen successfully in Tris-Egg yolk-Citrate-Fructose diluents for using in Artificial Insemination.Not Availabl

Malaria parasite burden and treatment seeking behavior in ethnic communities of Assam, Northeastern India

Objectives: The objectives of the study were to define the infectious reservoir of malaria with particular reference to transmission dynamics of Plasmodium falciparum, and to ascertain the disease trends in view of the existing containment practices and treatment seeking behavior in malaria endemic communities of Assam, India. Methods: Cross-sectional surveys were conducted in population groups of malaria endemic districts of the state to determine parasite prevalence, and data were analysed retrospectively for the years 1991-2003 to ascertain the disease trends. Structured questionnaire based surveys were conducted to study the treatment seeking behavior and practices of healthcare providers. Results: P. falciparum and P. vivax were the only two parasite species encountered, the former being in the majority (>60%). Malaria transmission was persistent, and a seasonal peak of P. falciparum was consistently observed during the months of heavy rainfall (April to September). Among children (5-15 years) there was a significantly higher malaria parasite rate as compared to the <5 years age group and adults (>15 years). There was a decline in parasite rates for all age groups over the years of the study that could not be attributed to vector control intervention intensities and/or meteorological factors. Conclusions: The persistence of P. falciparum is attributed to the emergence of drug resistant varieties, inadequate interventions and treatment seeking patterns, and for its containment focused intervention measures are advocated in partnership with the communities

Assessment of PAR Interception and Radiation Use Efficiency on Tomato Growth and Yield in the Upper Brahmaputra Valley Zone of Assam, India

A field experiment was conducted in Jorhat, Assam during the rabi season of 2019-20 to examine the effects of PAR interception, radiation use efficiency, and modified microclimates on tomato growth and yield. The variety Arka Rakshak was grown in split plot design with 4 dates of planting (P1: 25th October, P2: 14th November, P3: 3rd December, and P4: 8th January) in main plots and three types of mulching (M0: no mulch, M1: rice straw mulch, and M2: black polythene mulch) in sub-plots. Measurements of incident PAR (IPAR), reflected PAR (RPAR), transmitted PAR (TPAR) were taken at 10 days regular intervals. The results showed that IPAR ranged from 531 to 1431 μ mol s-1 m-2, with an average of 1140.4 μ mol s-1 m-2. RPAR varied between 41 and 285 μ mol m-2 s-1 under different microclimates. The tomato yield ranged from 76.6 to 392.6 q ha-1, with an average of 234.9 q ha-1. Planting on November 14th (P2) provided the most favorable microclimate conditions, while black polythene mulch (M2) was found to be the most suitable for crop growth, yield, and radiation use efficiency due to increased soil temperature. The study indicated that selecting the right planting date and implementing black polythene mulch can enhance tomato growth, yield, and radiation use efficiency in Upper Brahmaputra Valley Zone of Assam (Jorhat) agro-climatic condition

Not AvailableAn experiment was carried out to study the electrophoretic profile of sperm membrane proteins in Assam Hill goat (AHG) bucks and their correlation with fresh semen characteristics. Ejaculates (64) consisting of 8 each from 8 bucks were collected by artificial vagina method. Each ejaculate was split into 2 equal parts. First part was used for fresh semen evaluation and the other part for protein study. Sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) indicated 20 different protein bands with molecular weight ranging from 10 kDa to 75 kDa. Among the 20 proteins, only 6 proteins bands were consistently present in all 8 bucks (100%). Protein bands with molecular weight 10, 14, 22, 28, 55, 57 and 60 kDa showed significant positive correlation with certain parameters of the fresh semen, while 47 kDa protein band presented negative correlation with fresh semen characteristics in AHG bucks. In conclusion, the proteins showing significant positive correlation with fresh semen characteristics might serve to screen semen of AHG bucks for breeding programmes.Not Availabl
