We evaluated the effect of monochromatic and combined light emitting diode (LED) colour on performance, ovarian morphology, reproductive hormone biochemical blood parameters in laying hens. A total 600 Hy-line Brown pullets, 12 weeks age, were divided (25×4×6 = birds × replications treatments) as follows: red (R), green (G), blue (B), combinations R → G B treatments. Fluorescent white (W) was control. The results showed that higher egg production found under combination treatments, heavier...

This study observed the effect of different LED light colour on behaviour and fear responses broilers. In experiment 1, 400 broilers were placed into eight treatments. 2, six colours with five age groups considered. use a red red–yellow mixed significantly increased walking behaviour. Consequently, sitting standing found to be wavelength dependent, whereby short (blue, green–blue) treated birds spent more time than that under long (red, red–yellow). Consistently in feeding green treatment...

This study investigated the physicochemical parameters (pH, Temperature, DO, ORP, TDS and EC) of water quality along with 12 heavy metals concentrations in Dhaleshwari River. DO EC concentration indicated presence impurities higher salt content respectively. Various indices were applied to evaluate environmental human health risks. The average value Nemerow's pollution index (PN) was found be 41.2, river seriously polluted. Metal Index (MI) threshold warning for drinking purpose. Average HPI...

The present study evaluated the effect of monochromatic and combinations light emitting diode color on performance behavior laying hens. At 12 weeks age, 600 Hy-line Brown pullets were randomly divided into eight lighting treatments with three replicates 25 birds in each room. lightning was set-up as follows; white (W, control; 16 h/d), red (R; 618-635 nm; green (G; 515-535 blue (B; 455-470 red→ (R→G; 14 h→2 (R→B; green→ (R→G→B; h/d) blue→ (R→B→G; treatments. colors significantly influenced...

An experiment was conducted to investigate the effect of monochromatic and mixed light color on performance, bone, meat quality, blood properties immunity broiler chicks. In 1, 1,200 Ross×Ross 1-day old chicks were equally allotted following 8 treatments with 3 replications: red (R), yellow (Y) green (G), blue (B), R×Y, Y×G, G×B colors. Fluorescent white control. Experiment 2 considered similar (6 4 replications) except R R×Y not tested. Light (24 L: 0 D) intensity (0.1 watts/m2) maintained...

An experiment was conducted to evaluate the effect of dietary metabolizable energy (ME) and crude protein (CP) on performance, egg quality, blood properties, bone characteristics yolk fatty acid composition organic laying hens. At 23 weeks, a total 600 Brown nick hens were randomly distributed into 24 outdoor pens (4 replicate pens/treatment; 25 birds/pen) given (2750, 2775 2800 kcal ME/kg) CP (16 17%) resulting in 3×2 factorial arrangement treatments. The lasted weeks. performance not...

This study was performed to observe the effect of monochromatic light emitting diode (LED) colour and bird age on behaviour fear response ducks. A total 200 1-day-old ducklings were used in experiment (two replications, 25 ducklings/pen), lighting set up as follows: white (W, control, 400-770 nm), yellow (Y, 600 green (G, 520 nm) blue (B, 460 LED lights. Ducks subjected 23L: 1D h with 0.1 Watt/m 2 intensity. Video recorded twice per day (2 morning afternoon) observed five consecutive days...

According to the World Health Organization (WHO), At least 2.2 billion individuals worldwide have near or far vision impairment out of 7.9 populations. In at 1 cases, about half them, might been prevented is currently untreated. The primary causes and loss are uncorrected errors eye disorders. majority persons over age Fifty visual blindness. Visual misfortunes two terms that be used describe handicaps. This makes it difficult for them go their daily activities such as shopping, strolling,...

Summary Two studies were conducted separately with different combinations of light emitting diode (LED) colour to evaluate the performance, blood properties, meat fatty acid composition and immunity broiler chicks. In Experiment 1, 1536 one day old Ross × chicks randomly divided into 8 treatments three replications: red (R), green (G), blue (B) red→green (R→G), red→blue (R→B), red→green→blue (R→G→B) R→B→G where fluorescent white was control. 2 comprised 6 treatments, including pure (PB),...

This study was undertaken to investigate the influence of multi-probiotics, fermented ginseng byproducts and sulfone as an alternative probiotics on performance, intestinal microflora immunity broiler. A five weeks trial conducted with one day old Ross<TEX>${\times}$</TEX>Ross broilers (n=340), divided into groups which further 4 replicates 17 birds in each replicate. Birds were assigned 5 dietary treatments control, antibiotic avilamycin (AB), multi-probiotics (MP), (FS) (FGB). Growth...

Different housing systems have considerable influence on performance in poultry production. Therefore, the present study was undertaken to investigate impact of different performance, bone mineral density and egg yolk fatty acid composition laying hen. Hy-line brown pullets (n=450) 12 weeks age were randomly divided into 3 with 6 replicates 25 birds each room. A diet 2,750 kcal/kg ME 16.5% CP assigned all birds. The provided free access feed water. Significantly (P<0.05) higher values for...

Background and Objective: There is enormous scope of meat type duck farming but limited feeding management guidelines hampering to harvest the potentiality.Therefore, current study was carried out evaluate growth performance Pekin ducks reared in complete confinement system for 56 days by diets various nutrient concentrations.Materials Methods: To achieve goal, a total 272 day old ducklings mixed sex were used.Four different experimental considered as treatment groups having four...

Abstract Strategies for drug discovery and repositioning are an urgent need with respect to COVID-19. We developed "REDIAL-2020", a suite of machine learning models estimating small molecule activity from molecular structure, range SARS-CoV-2 related assays. Each classifier is based on three distinct types descriptors (fingerprint, physicochemical, pharmacophore) parallel model development. These were trained using high throughput screening data the NCATS COVID19 portal...

Milk contamination by dairy workers' spoiled hands, unclean utensils, microbes, and polluted water has caused many milk-borne epidemics. Most zoonoses are also contracted drinking infected milk. Bangladesh lacks milking hygiene farmer awareness, the milk cleanliness of farmers awareness practices in different regions was accessed. This study aimed at documenting present management producers particular districts Bangladesh. From June 2020 to 2022, 300 small cow owners twelve areas were...
