Feeding and Recycling Dried Poultry Waste to Laying Hens
T_e high proportion of feed costs in total operating expenses (1,2,6) indicates that the utilization of feed by the birds is closely related to the profitability of >oultry operations. The relationship between feed conversion (expressed as a ratio between weight units of feed consumed per weight unit of product) and profitability (defined as an increment .of total income over total costs) is es...متن کامل
In this experiment 240 Hy-Line (W-36) laying hens from 65 to 75 weeks distributed in 5 treatments and 4 replicates (12 birds per replicate) in a completely randomized design were used. The amounts of watermelon skin meal (WSM) used to set the treatments were 0, 0.5, 1, 1.5 and 2% in 1 to 5 experimental groups. The results showed that using WSM up to 2% significantly improved the performance and...متن کامل
Evaluation of limit feeding corn and distillers dried grains with solubles in non-feed-withdrawal molt programs for laying hens.
An experiment was conducted using 504 Hy-Line W-36 Single Comb White Leghorn hens (69 wk of age) randomly assigned to 1 of 7 treatments. These treatments consisted of a 47% corn:47% soy hulls diet (C:SH) fed ad libitum; a 94% corn diet fed at a rate of 36.3, 45.4, or 54.5 g/hen per day (CORN 36, CORN 45, and CORN 54, respectively); and a 94% corn distillers dried grains with solubles (DDGS) die...متن کامل
Two trials conducted in 1996-97 measured BW and body condition score changes of cows fed different sources of degradable intake protein, including dried poultry waste and soybean meal, while grazing low-quality winter forages. In Trial 1, 60 spring-calving cows (5 yr; 555 kg) were used in an individual supplementation trial. Cows were gathered three times a week, sorted into individual pens, an...متن کامل
This study aimed to investigate the responses to abrupt changes in feeding and illumination during the egglaying period. Six hens were housed individually in cages under constant environmental conditions, with a photoperiod of 15 h (0400-1900) and ad libitum access to food for 10 days. Then the same hens were subjected to a feed withdrawal trial (between 1200 and 0830), followed by a 5-h reduct...متن کامل
