Rapid growth in organic production in the past 20 years is due to consumer concerns about the impacts of conventional agriculture on the environment, food safety, and quality. There are considerable variations in nutrient concentration and the rate of mineralization among organic fertilizers. Some organic fertilizers and application rates are specific to soil types, which affect the nutrient po...

Climate change has been responsible for the high prevalence of heat stress (HS) among broiler chickens. In this research, efforts are made to curb negative impact HS on chickens by modifying feed and cage floor. The blood profile physiological responses supplemented with nucleotide turmeric powder kept in different floor cages were recorded (litter, slatted, combination slat-litter). A total 24...

Growers often apply high amounts of chemical fertilizers for vegetable production and this application contributes to concerns about nitrate levels in food. An experiment was conducted to investigate soil N amendment effects for reducing the nitrate accumulation and improving the quality of fresh purslane (Portulaca ...

Litter is the main source of ammonia (NH3) in broiler houses. The quality thereof affects amount NH3 volatilized and emitted from house as well welfare birds. A trial was conducted to determine how addition water litter (by spraying surface) raking or leaving undisturbed will influence concentrations at level, composition, bird welfare, performance under experimental conditions. total 2160 Ross...

Thirty-two Alpine doelings (15 wk of age, 12 ± 2.05 kg) were randomly allocated to four treatments to evaluate the use of deep-stacked broiler litter (BL) and urea-treated wheat straw (UWS) as feedstuffs. In all treatments, UWS or untreated wheat straw (WS) was fed for ad libitum consumption along with a concentrate supplement fed at a prescribed percentage of BW. Treatments were: U B a corn-ba...
