AIM Yucca schidigera extract has been successfully used as feed additives in the poultry industry. It enhances the growth and productivity in broiler production. Hence, the present study was designed to analyze the effect of Y. schidigera extract in growth, carcass quality and behavior along with its economical utility in broiler rearing. MATERIALS AND METHODS Total, 120 numbers of day-old br...

Litter material was obtained from broiler birds, reared on chaffed straws of wheat (T1 to T4) and paddy (T5 to T8) at floor spaces of 0.15sq.m/bird (T1, T2, T5 & T6) and 0.18sq.m/bird (T3, T4, T7 & T8). The litter material was then mixed with 10% molasses (DMB).The treatment groups (T2, T4, T6 & T8) were inoculated by 1% (v/w) fermented milk on fresh weight basis whereas control groups (T1, T3,...

This research set out to evaluate the effect of combined biological and chemical nitrogen fertilizers on some corn hybrids. To this end an experiment was conducted as split plot on the basis of randomized complete block design with four replications. Main plots were included: use of chemical and biological fertilizers in four levels: 100% chemical fertilizer, 75% chemical fertilizer + 100% bio-...

Two commercially available acidifying litter treatments, aluminum sulfate (alum) and sodium bisulfate, were tested to determine their effects on Campylobacter and Salmonella colonization frequencies and populations associated with broilers raised on treated pine litter. To produce contaminated litter, broiler chicks were inoculated with two bacterial cocktails (multistrain mixtures of campyloba...

Two trials were conducted to investigate the effect of availability of perches on indices of leg weakness in broiler chickens. A third trial investigated the effect of litter substrate on similar indices of leg weakness in broiler chickens. Leg weakness traits examined were walking ability and tibial dyschondroplasia, tibial curvature, foot burn, and hock burn. Body weight was also measured in ...

Alternative N fertilizers that produce low greenhouse gas (GHG) emissions from soil are needed to reduce the impacts of agricultural practices on global warming potential (GWP). We quantified and compared growing season fluxes of NO, CH, and CO resulting from applications of different N fertilizer sources, urea (U), urea-ammonium nitrate (UAN), ammonium nitrate (NHNO), poultry litter, and comme...

Abstract Crabgrass ( Digitaria spp.) is deemed as a productive and nutritious warm‐season annual forage for livestock in the U.S. transition zone. However, there limited information about nitrogen (N) source rate effects on productivity nutritive value of crabgrass North Carolina. Herbage accumulation (HA), N removal, crude protein (CP), total digestible nutrients (TDN), tissue nitrate (NO 3 − ...

Carbon dioxide balances are useful in determining ventilation rates in livestock buildings. These balances need an accurate estimation of the CO(2) produced by animals and their litter to determine the ventilation flows. To estimate the daily variation in ventilation flow, it is necessary to precisely know the daily variation pattern of CO(2) production, which mainly depends on animal activity....
