Feed Conversion and Feeding Behaviour in 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 کاملFeeding time and feeding rate and its relationship with feed intake, feed efficiency, growth rate, and rate of fat deposition in growing Duroc barrows.
Because feed is the major cost to pork production, management practices and breeding strategies are aimed at optimizing feed intake. Knowledge about the shape of feed intake and feeding behavior curves may be of interest for optimization of lean meat production. This study investigated trends based on daily measurements of feeding behavior in 200 Duroc barrows, originating from 5 sires and 200 ...
متن کاملVoluntary feed intake and feeding behaviour of group-housed growing pigs are affected by ambient temperature and body
́ The effect of ambient temperature on individual feeding behaviour was studied in six groups of Pietrain 3 Large White barrows. In experiment 1 (two groups), ambient temperature varied in a cyclic way from 22 to 128C and 12 to 228C with three or four consecutive days at each of the following temperatures: 22, 19, 16, 14 or 128C. Similarly, in experiment 2 (two groups), temperature varied from 1...
متن کاملDetermination of optimum feeding rate expressed as percent of body weight in Persian sturgeon, Acipenser persicus
The present study was conducted to determine the best feeding rates expressed as percent of body weight in Persian sturgeon fingerlings at different body weights. Eighteen fiberglass tanks each holding 30 fingerlings with an average initial body weight of 19.45 ± 0.5 g were used in this experiment. Six different feeding trials (1, 2, 3, 4, 5 and 6 percent of body weight) were employed an...
