    Leg Health in Large Broilers

    Even though, these leg problems seem to have a low incidence, they are very prevalent and all flocks have at least one percent of birds with some type of leg problems. The live production losses are just a small part of the economical impact of leg problems. Current statistics suggest that the downgrades and carcass trims associated with broilers that have leg problems increase costs per kilo of live weight. Lame birds spent much more time lying in the litter and bring more contamination to the processing plant increasing problems of food safety. Lame broilers have more condemnations like breast blisters, scratches and inflammatory processes (IP). Vaillancourt and Martinez (2002) reported a correlation between IP and angular leg deformities. Some of the skeletal deformities affect the operation of automatic evisceration and deboning equipment, thus impacting processing line speeds, the requirement of manual trimming and meat losses. Additionally, bone fragility affects the color quality of the deboned products and bone fragments represent a physical hazard. These facts indicate that improving leg health in broilers may bring several economical benefits to a broiler operation beyond addressing the welfare issues.

    Consumer Concerns About Hormones in Food :

    Can steroid hormones in meat affect the age of puberty for girls?

    Early puberty in girls has been found to be associated with a higher risk for breast cancer. Height, weight, diet, exercise, and family history have all been found to influence age of puberty (see BCERF Fact Sheet #08, Childhood Life Events and the Risk of Breast Cancer). Steroid hormones in food were suspected to cause early puberty in girls in some reports. However, exposure to higher than natural levels of steroid hormones through hormone-treated meat or poultry has never been documented. Large epidemiological studies have not been done to see whether or not early puberty in developing girls is associated with having eaten growth hormone-treated foods.

    Fishmeal and meat-meal were popularly used in poultry feed, but the increased production, improved availability and better awareness of soybean meal has led to its replacing fishmeal and meat-meal in most poultry rations. It should be mentioned that farmers have faced production problems owing to the bacterial contamination of fishmeal and meat-meal. The quality of fishmeal is also very poor.

    Feed of animal origin: meat meal, fish meal, squilla meal, hatchery waste and bone meal are used. However, farmers face production problems due to bacterial contamination of fish and meat meal.

    Feed additives: additives commonly used are antibiotics (usage not banned in India) prebiotics, probiotics, enzymes, mould inhibitors, toxin binders, anti-coccidial supplements, acidifiers, amino acids, antioxidants, feed flavours, pigments and herbal extract of Indian origin.

    Some links and what they say:

    1. http://grist.org/factory-farms/2011...practice-of-lacing-chicken-feed-with-arsenic/

    Inorganic arsenic is the highly poisonous stuff — see the absurd and wonderful Cary Grant classic Arsenic and Old Lace, or the EPA’s less whimsical take here and here [PDF]. The fact that the organic arsenic added to feed turns inorganic when it makes its way into manure is chilling, given the mountains of concentrated waste generated by factory poultry farms.

    Then there’s the question of arsenic traces in industrial chicken meat. In 2006, the Institute for Agriculture and Trade Policy (IATP) tested chicken samples from supermarkets and fast-food joints — and found that 55 percent contained detectable arsenic. Citing the EPA, IATP reckons that 55 percent of arsenic found in poultry meat is inorganic, i.e., toxic. And here’s another way arsenic from poultry feed gets into the food supply: the jaw-dropping, mind-boggling practice of feeding chicken shit to cows. But that’s a topic for another post — one, in fact, that I’ve already written.

    animal protein sources (meat and bone meal, dried whey, fish meal, etc.) ...
    ....Meat and bone meal is an excellent source of minerals, particularly calcium and phosphorus, as well as being a good protein source...
    ...Corn, wheat, oystershell, and meat scraps are fed cafeteria-style, so the birds can choose what they need...

    Fat from animal source as well as from vegetable source are used in feeds.
    Use of tallow and lard (pig fat) is mentioned.
