Massive amounts of pig manure are produced by intensive pig farm in China, and the composition of pig manure has changed much due to the use of feed additives. However, little is known about the exact Cu (copper) feed as additives or present as contaminants in pig feed and the residues in feces. One hundred and thirty-seven feeds and one hundred and forty-two fecal samples from 48 pig farms wer...

There are considerable differences in the basic feeds used by the Australian Pig Industry relative to those used overseas. Maize and soyabean meal form the basis of the USA and Canadian feeding systems, and barley and soyabean meal the basis of the feeding systems in Western Europe. In Australia, wheat, barley and sorghum are the major cereals fed, and meat and bone meal, soyabean meal, cottons...

This study was conducted to evaluate the effects of lavender (Lavandula angustifolia)extract as an alternative to flavophospholipol on performance, carcass characteristics, antioxidant status,meat quality, intestinal morphology and ileal microflora of broilers. A total of 220 day-old male broiler chicks (Ross 308) were used in a completely randomized design with five treatments each re...

introduction corn and wheat are the grains most routinely used in commercial poultry diets. for consumption of these cereals, there are a competition between humans and mono-gastric animals. due to corn crop limitation in iran, approximately 50% of the corn required for poultry nutrition is supplied through imports. since triticale is more resistant to various diseases, dry weather and in simil...

The objectives of the present study were to evaluate the anatomic localization of porcine reproductive and respiratory syndrome virus (PRRSV) in naturally infected pigs and to determine whether oral fluid could be used to detect the virus in infected animals. Two sows, seven 2-month-old grower pigs, and 70 6-month-old gilts were included in this study. PRRSV in sera and oral fluid were identifi...

BACKGROUND Growers have enthusiastically embraced crops genetically modified to express Bacillus thuringiensis (Bt) proteins for insect control because they provide excellent protection from key damaging insect pests around the world. Bt crops also offer superior environmental and health benefits while increasing grower income. However, insect resistance development is an important concern for ...

Coral reefs distant from human population were sampled in the Red Sea and one-third showed degradation by predator outbreaks (crown-of-thorns-starfish = COTS observed in all regions in all years) or bleaching (1998, 2010). Models were built to assess future trajectories. They assumed variable coral types (slow/fast growing), disturbance frequencies (5,10,20 years), mortality (equal or not), and...

Abstract In New Zealand, potato crop yields of 90 t ha ?1 are achievable but at 55 , the average is becoming economically unsustainable. 2012/13, a grower-initiated survey found that Rhizoctonia solani and Spongospora subterranea (soil-borne pathogens) soil compaction were widespread in 11 Canterbury crops. Targeted areas these crops had measured yield losses 0 (healthy plants) – 42 (diseased, ...

The avocado grower is usually familiar with deficiency symptoms such as those caused by lack of sufficient iron (3), zinc (11), and nitrogen (4). Also excesses of certain elements produce characteristic symptoms which may be readily identified, e. g. chloride and sodium (2, 9). However, little information is available concerning the remaining elements absorbed by the tree, their symptoms along ...
