  • Gongruttananun, N 2018-03-01 00:00:00 Abstract This experiment was conducted to investigate the effect of a non-fasting induced molt using cassava meal on the eggshell quality, ultrastructure, and porosity in late-phase (74 wk old) H&N Brown laying hens. (deepdyve.com)
  • It was concluded that feeding the cassava molt diet for 4 wk could be an effective non-fasting molt method for improving eggshell quality, ultrastructure, and porosity in post-molt laying hens. (deepdyve.com)
  • Two studies were conducted to evaluate if laying hens can be successfully molted by ad libitum feeding various levels and sources of DDGS. (illinois.edu)
  • At the end of the 28 d molt period, all hens were fed a 16% CP corn- soybean meal layer diet. (illinois.edu)
  • An experiment was conducted using 588 Hy-Line W-36 hens (68 wk of age) to evaluate if laying hens can be successfully molted by ad libitum feeding various levels of 3 sources of distillers dried grains with solubles (DDGS). (illinois.edu)
  • Hens fed the C:SH diet had egg production near 0% during the last 3 wk of the molt period. (illinois.edu)
  • Hens on the other treatments did not have mean egg production below 17% during the molt period (wk 1 to 4), and the reduction in egg production varied among DDGS sources. (illinois.edu)
  • Thus, about 5 yr ago, the United Egg Producers (UEP) commissioned five universities to conduct induced molting experiments in order to develop alternative molting programs which employed non-feed withdrawal to molt laying hens. (illinois.edu)
  • The studies conducted to date used techniques ranging from feeding hens without added salt in the diet to using readily available, low cost feed ingredients to develop molt diets that are low in energy level and protein content. (illinois.edu)
  • The results of these studies indicated that molting laying hens without feed withdrawal can be done successfully. (illinois.edu)
  • Therefore, after five years of experimenting with non-feed withdrawal molting methods done in several university settings, the egg industry has successfully adopted these methods of molting laying hens. (illinois.edu)
  • In recent years, concern for the well-being of hens during an induced molt has been expressed by animal activists groups. (illinois.edu)
  • Two such groups, United Poultry Concerns and the Association of Veterinarians for Animal Rights, have petitioned the USDA and FDA to eliminate induced molting of laying hens in the U.S. They contend that hens experience stress and "extreme cruelty" due to the removal of feed which is necessary to induce a molt. (illinois.edu)
  • In one study, laying hens were fed very high levels of zinc and found that egg production was slightly better and egg weights were heavier for hens induced to molt when fed 1% zinc acetate and 1% zinc propionate compared to a conventional feed withdrawal method . (illinois.edu)
