This paper reported highly luminous zinc sulfide (ZnS) nanoparticles grown by microwave-irradiated single molecular precursors. The precursor was obtained by Schiff bases of S-benzyl dithiocarbazate (SBDTC) ligand using 5-Bromo-4-hydroxy-3-methoxy-2-nitro Benzaldehyde; 4NNbiscyno diethylamino benzaldehyde and p-amino acetophenone. The nanoparticles obtained were characterized by X-ray diffraction studies for structural analysis, transmission electron micrographs (TEM) for morphological analysis, and UV-Vis spectra for optical analysis. X-ray diffractograms exhibit mixed structures analysis (wurtzite and cubic) for particles obtained using 5-Bromo-4-hydroxy-3-methoxy-2-nitro benzaldehyde and 4NNbiscyno diethylamino benzaldehyde. However, the particles obtained by p-amino acetophenone Schiff bases of SBDTC exhibit only wurtzite structure. Variation in optical properties is also observed with the precursors used. The excellent optical properties of ZnS nanoparticles signify the role of microwave irradiation in synthesis. The Photoluminescence (PL) study shows the luminescence in the visible region and the maximum intensity for ZnS particles obtained by zinc complex of p-amino acetophenone Schiff base of S-benzyl dithiocarbazate. The microwave-assisted process can be used for large-scale production of nanoparticles for emitting light in the visible region in various detecting and sensing applications.
The present study was conducted to investigate the effect of different levels of dietary supplementation of turmeric powder at a rate 0, 1, and 2% on egg production, hatchability and internal egg quality characteristics of Japanese quails (Coturnix Japonica). A total of 225 numbers of 54 weeks old Japanese quails were randomly selected from the Poultry farm, Instructional Livestock Farm Complex, College of Veterinary Sciences and Animal Husbandry, Central Agricultural University, Selesih, Aizawl, Mizoram, of which 150 were female and 75 were male. The birds were divided equally into three treatment groups i.e. T0, T1 and T2 comprise of 75 birds each. T0, T1 and T2 were supplemented with 0, 1 and 2 per cent turmeric powder of basal diet respectively. Each group were again divided equally into five replicates trails. The mean Hen Day Egg Production (%) was significantly higher (P˂0.01) during 59th weeks of age in turmeric supplemented groups of T1 followed by T2. No significant difference was observed between the treatment groups in regard to hatchability percentage. Albumen index and Haugh unit were recorded as non- significant between the treatment groups. Yolk index and shell thickness was significantly higher at (P˂0.01) and (P˂0.05) respectively in 2 percent turmeric supplementation. The yolk colour score was found to be significantly higher (P˂0.01) with increased level of turmeric powder supplementation. Therefore, it is concluded that supplementation of 1% turmeric powder in the diet improve egg production while 2% inclusion improves the internal egg quality characteristics (yolk index and yolk colour) of quail eggs.
The present study was carried out to know the effect of feeding fermented liquid feed on haemato-biochemical parameters in the pre-weaned (1st week to 4th week) and post-weaned (5th week to 10th week) young pig. Fermentation was carried out with the help of bacteria, Lactobacillus acidophilus. The young pigs were divided into three groups; control, treatment 1 and treatment 2. The control, treatment 1 and treatment 2 was fed on dry feed, fermented liquid feed and combination of equal parts of fermented liquid feed and dry feed, respectively, from 7 days of age to 70 days of age. Except total leucocyte count, there was significant increase in haemoglobulin, packed cell volume, total erythrocyte level in treatment 1, followed by treatment 2 and control group. The biochemical parameters like total protein, albumin and globulin were non-significantly increased in treatment 1, whereas other biochemical parameters like glucose, triglyceride and total cholesterol were either significantly or non-significantly increased in treatment 2 and control. From this study, it can be concluded that there was improvement in the haemato-biological parameters of pre-weaned and post-weaned young pigs fed on fermented liquid feed.
