Effect of Histidine Supplementation on Growth Performance Characteristics, Hemato-biochemical Profile and Economics of Broiler Production
An experiment of five w weeks duration was conducted at Livestock Farm Complex, Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya to access the impact of histidine supplementation on growth performance, hemato- biochemical profile and economics of broiler production. Total 200 day old chicks were randomly divided into four dietary treatment and each group was further redistributed into five replicates containing 10 chicks in each i.e. control group (T1) with basal diet regimen, T2 group (Basal diet+ Histidine @0.05%), T3 group (Basal diet + Histidine @ 0.10%), T4 group (Basal diet+ Histidine @0.2%). Body weight, body weight gain, average daily gain, growth rate, feed intake, gain feed ratio, performance index, hemato-biochemical profile and economic efficiency were assessed. In the third, fourth and fifth weeks T3 group broilers body weight were significantly (P<0.05) higher than T1, T2 and T4 group. The average total feed intake as well as daily feed intake during the entire experimental period were significantly (P<0.05) lower in T3 group, with respect of control group. The T3 group birds had significantly (P<0.05) higher gain to feed ratio and performance index, as compared to control group. The serum glucose, total protein, albumin and globulin values were significantly (P<0.05) higher in histidine supplemented birds in all the dose regimen, as compared with control group. The cost of production of T1, T2 and T3 groups birds were comparable (P>0.05) but significantly (P<0.05) higher than T4 group. The birds supplemented with 0.10% histidine had significantly (P<0.05) higher feed price ratio, profitability and economic efficiency index, as compared with control group. The observation of break even output was lowest (P<0.05) in T3 and highest (P<0.05) in T4 group. So, it might be concluded that, the dietary supplementation of histidine @ 0.10 % has ability to improve the performance of broiler chickens.
Physical, Functional and nutritional quality characterization of microencapsulated Ber (Ziziphus mauritiana L.) fruit powder
Limited availability, lower shelf life, and lack of suitable technologies are major drawbacks for the limited utilization of Ziziphus fruit in processing industry. This study was carried out with the aim to enhance the shelf-life and retain the economic importance of Ziziphus by using spray drying process for Ziziphus powder production. Maltodextrin used as wall material in different concentrations and inlet air temperature were taken as independent variables to study their effect on major powder responses i.e., powder yield, water activity, color properties, vitamin-C, total flavonoid content, and total antioxidant activity. Lower encapsulant quantity (10-15%) was inefficient in limiting the degrading impact of temperature on bioactive compounds. Higher encapsulant quantity of 25% had masking effect on bioactives concentration and their associated activity retention. Therefore, 170°C inlet air temperature, 20% maltodextrin concentration and 60ml/h feed flow rate were optimized to obtain 22.30 ± 3.09% for producing commercially viable powder with lowest water activity (0.295 ± 0.02), best color retention (L* 88.52 ± 0.70, a* 1.13 ± 0.49, b* 12.25 ± 0.62), highest bioactive retention (vitamin C 14.56 ± 0.59 mg/100g, flavonoid content 388.00 ± 0.46 mg/100g) and associated functional activity (antioxidant activity 1.89 ± 0.56 to 2.10 ± 0.50/g).
EFFECT OF MULCHING PRACTICES, VARIETIES AND FERTILITY LEVELS ON PHYSIOLOGICAL GROWTH PARAMETERS OF CLUSTERBEAN
A field experiment was conducted during the kharif season of 2013 and 2014 to evaluate the effect of mulching practices, varieties and fertility levels on physiological parameters of clusterbean at the Research Farm, College of Agriculture, Gwalior. The results revealed mulching practices, varieties and fertility levels on physiological parameters of clusterbean that increased the value of CGR, AGR and LAI up to 90 DAS, RGR up to 60 DAS and LAR up to 30 DAS growth stage and then decline up to maturity. The values of dry matter, CGR, RGR, AGR and leaf area index were recorded higher with plastic mulch, HG-563 and 75% RDF +VC 5t/ha. over remaining mulch, varieties and fertility levels. While leaf area ratio (LAR) was recorded maximum in Control (N0P0K0) over other fertility levels at all growth stages.
Differential varietal reaction of Macrophomina phaseolina incitant of charcoal rot disease
Charcoal rot incited by Macrophomina phaseolina is an economically important disease of sesame. Sesame is one of the important oilseed crops and high valued due to nutritional and medicinal properties. Weather variables predisposed M. Phaseolina for quantification of disease progression at different rate and differential reaction on sesame varieties. Differential reaction of M. phaseolina on sesame varieties was studied during three different dates of sowing. Progression of disease was found highest during period of 18th August and 23rd August in all dates of sowing. Maximum disease incidence was recorded in early sown crop followed by mid and late sown conditions. Higher charcoal rot disease incidence was recorded in variety HT1 than HT2 during different dates of sowing. The progression of charcoal rot disease over a time was assessed by area under disease progress curve. Area under disease progress was recorded higher in variety HT1 than HT2 in all three different dates of sowing. It was observed maximum during early date of sowing followed by mid and late sown conditions.
Determination of Drying kinetics and Cellulose content of Punica Granatum L. Peels
The pomegranate tree, scientifically known as Punica granatum L., belongs to the Punicaceae family and yields a fruit widely consumed for its traditional and medicinal properties. Peels of pomegranate are highly nutritios but go waste and unutilized. So, a study was conducted to determine the drying kinetics and cellulose content of Punica Granatum L. Peels. Page model was used for drying kinetics. It was found suitable for the three drying temperatures viz. 50, 60 and 70°C, respectively. Page model parameters n, ln K and co efficient of determination (R2) at 50, 60 and 70°C ranged from -0.415 to -0.490, 2.222 to 2.352 and 0.979 to 0.987, respectively. the surface area (s) and volume (v) of the peel slices were calculated to be 3 mm² and 1.5 mm³, respectively. The moisture diffusivity (D) value at drying temperatures of 50 °C, 60 °C and 70 °C was found to be 2.73 × 10-3 m2/s, 3.16 × 10-3 m2/s and 5.25 × 10-3 m2/s respectively. Activation energy (Ea) of the peel can be was found to be 39 kJ/mol. Cellulose content 50, 60 and 70°C varied from 542 to 695 mg/100g.
