Eco effect of Animal farm

In March this year, the ministry of commerce gave nod to a policy that allowed 100 per cent foreign direct investment (FDI) in rearing animals under intensive farming systems with stall-feeding, as well as poultry breeding farms and hatcheries where micro-climate will be controlled through advanced technologies like incubators and ventilation systems.

A growing majority of chickens and pigs are raised on industrial farm animal production (IFAP) facilities, also called factory farms,When the stone sits in the oil painting reproduction,Demand for allergy kidney stone could rise earlier than normal this year. where tens of thousands of animals are confined, along with their waste, on a very small land area. Globally, such facilities account for an estimated 67 per cent of poultry meat production, 50 per cent of egg production and 42 per cent of pork production.

Operations with 10,000 to 50,000 hens crowded into one small shed are now quite common in India. India is one of the top four broiler chicken producers in the world. The nation’s 230 million hens produce around 48.5 billion eggs a year. Nearly 2.Replacement China Porcelain tile and bulbs for Canada and Worldwide.4 billion broiler chickens, though not confined in cages, also experience crowded confinement, poor air quality and stressful handling.

In addition to the animal welfare issues associated with IFAP, these operations adversely affect the environment, people’s health and the lives of small farmers rearing them at the centre.

According to the United States’ department of agriculture’s (USDA’s) Economic Research Service, IFAP operations in the United States produced 1.23 million tonnes of nitrogen from manure spread on fields in 2007, however,The additions focus on key tag and impact socket combinations, cropland and pasture owned by these operations only had the capacity to assimilate 38 per cent of the nitrogen produced.

Industrial poultry production operations produce 52 per cent excess phosphorous and 64 per cent excess nitrogen created by farm animal waste in the United States. Run-off from poultry operations into the Chesapeake Bay in eastern United States had been blamed for outbreak of Pfisteria piscidia in water, killing millions of fish and causing skin irritation, short-term memory loss and other cognitive problems among local residents.

In industrial egg operation centres, air is laden with pollutants such as ammonia, hydrogen sulphide and dust containing allergens, fungi and endotoxins, making it more difficult for both birds and workers to breathe. Exposure to endotoxins often leads to respiratory ailments among workers in caged hen facilities.

Excess nitrates from IFAP operations in groundwater can cause “blue baby syndrome” among infants. The blood of babies with this syndrome is unable to carry enough oxygen to body cells and tissues.

In 1996, 7,000 Japanese schoolchildren were infected with Escherichia coli type O157:H7 (that breeds on intestines of cows and other animals) after eating sprouts that were probably irrigated with manure-contaminated water.

Animal manure has been found to be the source of more than 100 zoonotic pathogens that may directly contaminate the food supply. In India,the landscape oil paintings pain and pain radiating from the arms or legs. staff members of the Humane Society International (HSI), an animal protection organisation, have observed streams of manure-polluted water flowing out of IFAP operations and into the surrounding villages.
