“…Moulting refers to periodic shedding and feather replacement, coinciding with a decrease in the reproductive efficiency function (Berry, 2003) and body weight loss of about 25% (Mrosovsky and Sherry, 1980). These include high dietary zinc supplementation (Sandhu et al, 2006), low calcium (Breeding et al, 1992) and low sodium diets (Berry and Brake, 1985), wheat middling (Biggs et al, 2003), using barley (Onbasilar and Erol, 2007), cottonseed meals (Davis et al, 2002), jojoba meal (Vermaut et al, 1997), alfalfa (Donalson et al, 2005;Landers et al, 2005;Aygun and Olgun, 2010), oat (Fletcher et al, 1981;Aygun and Yetisir, 2009) and rice bran (Santos et al, 2014) in diets. This practice became the most adopted tool to maintain the production potential of laying hens until the early eighties.…”
