Microbial inhibition test thin layer chromatography used for screening ultra-high performance liquid estimate the concentrations samples.Tetracycline, amoxicillin, ciprofloxacin significantly (p ≤ 0.05) higher...

Free-range laying hen housing systems are prevalent in Australia and perceived by consumers to provide greater opportunities for the expression of natural behaviour resulting higher welfare. However, all have both benefits risks scientific evidence is needed on welfare outcomes free-range systems. In this review, literature summarised from past 10 years, research conducted within or internationally with brown laying-hen strains kept It compiles information range use hens, while range,...

In Australia, free-range layer pullets are typically reared indoors, but adult layers go outdoors, and this mismatch might reduce adaptation in laying environments. Enrichments during rearing may optimise pullet development subsequent welfare as hens. the outdoor environment, hens have greater opportunities for exercise natural behaviours which contribute to improved health welfare. However, environment also result potential exposure parasites pathogens. Individual variation range use thus...

In Australia, free-range egg production pullets are typically reared indoors, but adult layers get outdoor access. This new environment may be challenging to adapt to, which could impair and/or quality. Adaptation might enhanced through rearing enrichments. We 1386 Hy-Line Brown® chicks indoors with three treatments across 16 weeks: (1) a control group standard litter housing conditions, (2) novelty providing novel objects that changed weekly, and (3) structural enrichment custom-designed...

Pregnancy-related complications and their consequences pose significant public health challenges, particularly in rural developing areas where healthcare resources are limited. Monitoring clinical parameters during pregnancy improves diagnosis, treatment, maternal prognosis. This database includes records of pregnant patients from Kurigram General Hospital, Bangladesh. It captures core such as age, blood pressure (systolic diastolic), sugar levels, body temperature, BMI, current mental...

Inconsistency between the environments of indoor pullet rearing and adult outdoor housing may increase fearfulness in free-range hens. Rearing enrichments and/or range use reduce fearfulness. Hy-Line Brown® chicks (n = 1700) were reared inside across 16 weeks with three enrichment treatments: weekly changing novel objects, custom-designed perching/navigation structures, or no additional enrichments. Pullets transferred to a system at age, access provided from 25 weeks. At 62 weeks, 135 hens...

Results:The found higher number RBC (million/cumm) PCV% the 48 above (18.23 ± 1.89 28 3.2) respectively.Besides,...

Enrichments during pullet rearing may improve adaptation and welfare of hens as they move from indoor to a free-range system. Individual variation in outdoor ranging also affect welfare. This study assessed the effects enrichments an imposed environmental stressor on hen egg quality along with association ranging. Hy-Line Brown® chicks (n = 1386) were reared indoors until 16 weeks 3 enrichment treatments including 'control' group standard floor litter, 'novelty' that received novel objects...

Diversification of cropping pattern coupled with the development suitable technology packages is crucial to meet ever-increasing demand for diversified products and sustained farmers' incomes. We evaluated different woodlot-based multistoried agroforestry systems their effectiveness mitigate devastating effects climate change by offering multifaceted benefits. Specifically, present study aimed assess yield probability woodlot based system two vegetables, i.e., potato brinjal during period...

B angladesh is a densely populated country with 80% of the rural people engaged cattle rearing (Siddiki et al., 2010).The total and goat population Bangladesh 23.8 million 26.2 respectively (Anon, 2020).Compared to neighbouring countries like India, Nepal Myanmar, has low produc-tivity in milk production (Uddin 2011).Estimated meat are 9.3 7.2 metric tons respectively; having deficiency 5.6 surplus 0.02 2017).Cattle extremely important household farmers; because direct link family's income,...

D airy farming in Bangladesh getting popularity day by and presently around 6 million dairy cattle of crossbred high yielding cows are distributed both household commercial farms across the country which produces 9.4 metric ton liters milk per year (Alam Sarder, 2010; DLS, 2019).Around 70% farmers smallholders having 1-3 farm contribute to 70-80% total demand (Hemme et al., 2008; Uddin 2012).Dairy produce 200-250 liter 305 days lactation period (Hussain, 2013).Production disease like...

Free-range pullets are reared indoors but the adult hens can go outside which is a mismatch that may reduce adaptation in laying environment. Rearing enrichments might enhance pullet development and adaptations to subsequent free-range housing with impact on behavior health measures including gut microbiota. Adult vary range use also be associated microbiota composition. A total of 1,700 Hy-Line Brown® chicks were across 16 weeks three enrichment treatment groups: "control" standard litter...
