Production performance and egg quality characteristics of commercial layer chicken on dietary supplementation of Panchagavya and Phytogenic feed additive
The objective of this study was to evaluate the effect of dietary supplementation of panchagavya (PG) and phytogenic feed additive (turmeric) in commercial layers on production performance and egg quality characteristics. Four-hundred-day-old commercial layer chicks (BV-300) were randomly allotted into eight treatment groups with five replicates of ten chicks per replicate and reared upto 30 weeks of age. Dietary treatment groups consisted of T1 (control)-basal diet and T2 group were fed basal diet with oxytetracycline-50 ppm. The groups T3, T4 and T5 were fed basal diet supplemented with 5, 7.5 and 10 g/kg of panchagavya respectively. The other treatment groups T6, T7 and T8 were fed basal diet supplemented with turmeric 1 g/kg in combination with panchagavya at 5, 7.5 and 10 g/kg levels respectively. The egg production performance was recorded for the period from 19 to 30 weeks of age. Age at sexual maturity, age at 50 and 90 per cent egg production and feed consumption were recorded. The feed efficiency per dozen eggs, feed efficiency per kg egg mass, hen day and hen housed egg production were calculated. The egg quality characteristics such as egg weight, specific gravity, albumen index, haugh unit, yolk index, yolk colour and eggshell thickness were recorded. The results obtained from this study shown that the age at sexual maturity was significantly (P<0.05) earlier in all treatment groups except T7 (PG-7.5 g/kg and turmeric -1g/kg) group which attained sexual maturity in later age (129.40 days). No significant difference observed between the treatment groups for age at 50 and 90 per cent egg production. The results on hen day and hen housed egg production (per cent), feed consumption (g/bird/day) from 19 to 30 weeks of age showed no significant difference between the treatment groups. The overall feed efficiency per kg egg mass (19-30 weeks) showed significant (P<0.05) difference. Moreover, better feed efficiency per kg egg mass (2.35 and 2.37) was observed in T2 (antibiotic) group followed by T6 group (PG – 5 g/kg and turmeric -1 g/kg) as compared to other treatment groups. The results showed no significant effect on the egg quality characteristics such as shape index, albumen index, Haugh unit and yolk index of commercial layer chicken eggs between the treatment groups. Yolk colour (5.20) was significantly (P<0.01) higher in T6 (PG -5 g/kg and turmeric -1 g/kg) and T7 (PG -7.5 g/kg and turmeric -1 g/kg) groups as comparison with antibiotic fed group (4.50).
Response of ornamental plants under colored nets on vegetative, physiological, biochemical and quality parameters
The present research was conducted to find out the Effect of different colored shade nets on production and quality of various ornamental plants. The experiment consists of 25 treatments with three replications which were laid out in Factorial Randomized Complete Block Design. The treatments were combined with two factors as factor I with different colour shade nets are Green, White, Black, Red nets and Open condition and factor II comprises of different ornamental plants i.e., Pandanus veitchii, Epipremnum aureum, Sansevieria trifasciata, Aglaonema commutatum var. Redgold, Rhoeo spathacea were taken. The results revealed that the black shade net with combination of Epipremnum aureum had maximum plant height (338.87cm) and carotenoids 1.63mg/g was recorded. Red net with Rhoeo spathacea combination showed highest total leaf area (7098.24 cm2), photosynthesis rate (4.31), Crop growth rate (5.11 g m-2 day-1) and Relative Growth rate (5.55 g g-1 day-1) respectively. Plant spread and Dry matter production was found highest under red net and Pandanus combination. Green shadenet and Rhoeo combination showed maximum ascorbic acid (3.93 mg g-1) and leaf pH (6.32). Highest mean total chlorophyll (4.03 mg g-1) was observed under green net and Epipremnum and longest vase life (42.98 days) was reported under black net and Sansevieria. Black and red shade nets were shown to be more effective than other colour nets in enhancing the majority of plant characteristics. As a result, black or red nets can be utilised to substitute the commercially available green shade net for cut greens and potted plant production.
Influence Of Age At Slaughter On Fatty Acid Profile, Cholesterol Content And Tenderness Of Emu Meat
Sixteen emu birds were used to study the effect of the age at slaughter (15months and 18 months) on fatty acid composition, cholesterol content and tenderness of Emu meat. Fatty acid composition of emu meat was significantly affected by age at slaughter (P< 0.05). A highly significant difference (P< 0.01) was noticed between the Cholesterol content of the two age groups. Emus slaughtered at 18 months had more saturated fatty acids (P< 0.05) than those slaughtered at 15 months. The monounsaturated and polyunsaturated fatty acids were more in the younger age groups. Oleic acid (C18:1) was the predominant monounsaturated fatty acid and the polyunsaturated fatty acids such as the linoleic (C18:2) and linolenic (C18:3) were all significantly higher in the younger age groups. The attributes of tenderness like Fibre diameter (µm), Sarcomere length (µm), Myofibrillar Fragmentation index, Shear force value (kg/cm2) and Collagen content (mg/g) showed a highly significant difference between the two age groups.
Study of groundwater potentiality in rainfed plateau of Chhattisgarh using remote sensing and GIS
The present investigation on ground water potential tracks through remote sensing and GIS techniques was carried out for geo-spatial multi-criteria approach. Due to uneven rainfall trend increases demand of below ground water in southern Chhattisgarh, this is urgently needed for sustainable resources of ground water. The dendritic to parallel drainage pattern of area shows showing branches of tree networks and low homogeneity and uniformity. The maximum irregular to moderate irregular surface mainly indicates the occurrence of groundwater. The maximum loss of runoff water does not permit infiltration to recharge zones under groundwater. Slope having 1-3% exhibits mainly flat to gentle considered a ‘good’ category for the groundwater occurrence owing to more favourable to capacity of infiltration of surface factor regarding long term retention of runoff water which indicates low potential for development of groundwater. The area posses 31% cultivated land, 15% concrete, barren scrub and forest scrub covers 12% each with 11% of moderately dense forest providing huge chance of extraction of groundwater round the year (except 2-3 months) in this rainfed region. Area with very high, moderate, poor and very poor groundwater potentiality comprises 2185.43 km2, 519.35 km2, 239.98 km2, 1084.90 km2 and 0.34 km2 which covers 54.23%, 12.89%, 5.95%, 26.92 and 0.01% area in the region, respectively. The surface morphology of the region is characterized mostly by typic haplusterpts (30%) and lithic ustorthents (21%) are major soil types with sensitivity analysis on basis of weightage for all thematic layers exhibits variation from the empirical weights in groundwater potentiality is most response to lithology is a paramount important parameter in assessing groundwater water potentiality and then lineament density, geomorphology, slope and drainage density are considered.
Change study on spatio-temporal dynamics of Jagdalpur city landscape of Chhattisgarh, India using remote sensing and GIS - A case study
An attempt has been made to measure and monitor spatio-temporal dynamics of Jagdalpur landscape, Chhattisgarh, India using urban plan maps (1981), topographical sheets (1981), temporal Landsat 5 Thematic Mapper data for the years 1990 and 2018. The spatial alongwith temporal change in land use pattern over 1990 to 2018 has been observed that the more area occupied by vacant lands, low dense forest and scrub forest with 19.8, 15.9 and 15.3%, respectively in imageries of 1990 which is changed with 2018, first three classes low dense habitat (21.9%), habitat (19.2%) and vacant lands (13.5%) occupied more area; however, lowest (6.3%) is under dense forest. These changes in land use due to more development of colony and expansion of Jagdalpur city in west and south direction as educational hub transforming large cultivated lands over the period of time. Analysis of low dense habitat areas show that significant area has been increased from 14.3 to 21.9 per cent of TGA during 1990 to 2018. The majority of habitats are in core area of city, whereas in the year 2018, area under these settlements has been increased considerably in all directions. Analysis of out skirt agricultural lands of Jagdalpur city indicates that the vacant lands mainly noticed in western and southern parts with an area of 13.5 per cent and rainfed rice occupies in conjunction of western and southern parts of city with 8.0 per cent area of TGA. 2000 onwards, the western part of city has been developed as educational hub and opening of Medical college in southern part gained momentum for constructing colonies and purchasing lands on vacant and cultivated lands. This situation gears up eastern part after NMDC at Nagarnar.
