| Abstract: |
Two experiments were conducted to study the effect of drinking water nitrate on performance of fowl.Five hundred seventy six, day-old Arbor Acres broiler breederchicks were used for the first experiment, chicks were completely andrandomly divided into six groups, each group was presented by 4replicates of 17 female and 7 male chicks, The six groups of chicks wereassigned to receive one of six water treatments, factorial arrangement oftreatments was applied with 3 levels of drinking water nitrate (0, 30, and60 ppm) as sodium nitrate, and 2 levels of ammonia (0, 1 ° ppm) asammonium citrate. Main effects for drinking water nitrate and ammonia,and interactive effects with each other and with other factors, onperformance parameters, were studied,.Main effects for drinking water nitrate on performanceparameters of broiler breeder hens:.A significant DROP in daily water consumption was reported fordrinking water nitrate, on the other hand a significant increase in hen-day egg production percent was repotted for the increased level ofdrinking water nitrate..Non of the following performance parameters was found to besignificantly altered by drinking water nitrate:Overall body weight of the breeder flock, age and weight of hens atfirst egg production, total number of eggs per hen, both percentages offertility and hatchability, nitrate was also found to have no significanteffect on percentages of either dead embryos or pipped eggs,
