The objective of this experimental study was to examine the pathological effects of the intramuscular administration of gentamicin to growing chickens. Two experiments of 35 days’ duration were conducted simultaneously. In both experiments White Leghorn cockerels of 6 weeks of age were randomly divided into 4 groups and gentamicin was administered intramuscularly to the birds on days 1 and 3 at...

There is a paucity of data regarding the effect nutrient-enriched biochar amendments on nutrient dynamics in both soil and crops. This important because unlike pristine biochar, applied to minute quantities as large amounts may led over application nutrients loaded it. The current study examined effects phosphorus- nitrogen-enriched biochars macro micronutrients sandy leaf lettuce grown thereon...

The release of phosphorus (P) and zinc (Zn) from swine manure compost and from soils applied with swine manure compost can be accelerated by colloidal particles. This study investigated the concentrations and chemical species of P and Zn in water-dispersible colloids (WDCs) collected from swine manure compost by using X-ray absorption fine structure (XAFS) spectroscopy. A filtration and ultrace...

Ammonia, one of the main substances livestock odor, is reported to act as a major precursor secondary fine dust along with impact odor on public health due deterioration air quality, so systematic emission management needed. Livestock production ammonia mainly generated by hydrolysis urea in urine urease, hydrolytic enzyme. Therefore, this study, we aimed suppress inhibiting activity urease usi...

Sulfonamide antibiotics are a commonly used group of compounds in animal husbandry. They are excreted with manure, which is collected in a storage lagoon in certain types of confined animal feeding operations. Flood irrigation of forage fields with this liquid manure creates the potential risk of groundwater contamination in areas with shallow groundwater levels. We tested the hypothesis that-i...

A rapid and cleanup-free ultrasound-assisted extraction method is proposed for the simultaneous extraction of oxytetracycline, tetracycline, chlortetracycline, and doxycycline in manure. The analytes were determined using high-performance liquid chromatography with ultraviolet detector. The influence of several variables on the efficiency of the extraction procedure was investigated by single-f...

The paper presents an account of a ®eld plot experiment to investigate the in ̄uence of soil applications of neem-based (Achook and Suneem G) and crop fertilizer (urea and cattle manure) treatments, separately and in combination on free-living, and plant-pathogenic nematode populations and crop productivity. All the treatments signi®cantly decreased the number of plant-parasitic nematodes with i...

Aim: To find out the CH4 and CO2 emission pattern considerable amount of SOC sequestered by using different organic sources in sandy clay loam soil.
 Study Design: Randomized Block Design.
 Place Duration Study: The study was conducted a farmer's field at Ayanathur, which is geographically located 11°23’N latitude, 79°29'E longitude, an altitude +26 m MSL. confined to 2 years cycle fr...

Prediction of phosphorus (P) availability from soil-applied composts and manure is important for agronomic and environmental reasons. This study utilized chemical properties of eight composted and two non-composted beef cattle (Bos taurus) manures to predict cumulative phosphorus uptake (CPU) during a 363-d controlled environment chamber bioassay. Ten growth cycles of canola (Brassica napus L.)...

Two experiments were performed to determine the digestibility of diets with crude protein (CP) reduction supplemented amino acids (18.15; 17.15; 16.15 and 15.15%) growing pigs (30–50 kg), assess use nutrients account for manure excretion, evaluate performance, backfat thickness, Longissimus lumborum depth, plasma urea, aiming environmental impact through life cycle assessment (LCA); first time ...
