Escherichia coli O157:H7 (EcO157) shed in cattle manure can survive for extended periods of time and intervention strategies to control this pathogen at the source are critical as produce crops are often grown in proximity to animal raising operations. This study evaluated whether neem (Azadirachta indica), known for its antimicrobial and insecticidal properties, can be used to amend manure to ...

Background Poultry breeding has increased by 306% in Korea, inevitably increasing the production of manure which may contribute to environmental pollution. The nutrients (NP) in the manure are essential for crop cultivation and soil fertility when applied as compost. Excess nutrients from manure can be accumulated on the land and can lead to eutrophication. Therefore, a nutrient load on the fin...

ABSTRACT Given the lack of information on use spontaneous plants from Caatinga biome as green manure to produce grains, present work aimed agronomically and economically optimize cowpea production for grains their components when fertilized with equitable biomass amounts hairy woodrose (Merremia aegyptia L.) roostertree (Calotropis procera Ait.) in two cropping seasons a semi-arid environment. ...

this study investigated the effect of gnrh analogues on inducing ovulation of dominant follicle (df)and subsequent corpus luteum (cl) lifespan in the presence of norgestomet implant in holstein heifers. onday 6 to 8 of the estrous cycle (day 0 of the experiment), all heifers (n=15) received norgestomet implantfollowed by prostaglandin injection on days 0 and 1. on day 4, group 1 (n=4) and 2 (n=...

The prevalence of Cryptosporidium species in 1-2-year-old heifers was determined for 571 animals on 14 dairy farms in seven states on the East Coast of the United States. A fecal specimen collected directly from each heifer was processed to concentrate oocysts that were then examined by polymerase chain reaction (PCR). For every PCR-positive specimen the 18S rRNA gene of Cryptosporidium was seq...
