Abstract
This experiment included two stages growing squabs and laying pigeons at 1st and 2nd egg hatch. A 3 × 3 factorial experiment, using 3 dietary ME levels (2600, 2800 and 3000 Kcal /kg) and 3 supplemental CP levels (14, 16 and 18 %), was conducted to study the effects of dietary energy and CP levels.
a. First stage (Growing squabs):
A total number of 135 pairs of Baladi squabs obtained from three small scale pigeon hatcheries (aged 28-30 days), were allocated to nine dietary treatments, each containing 15 pairs presented in 15 cages of one pair each.
b. Second stage (Laying pigeons):
A total number of 81 pairs of Baladi pigeon (6-month-old) obtained from first stage assigned into 9 treatments each containing 9 pairs presented in 9 cages of one pair each. In each breeding cage the parents were able to feed their squabs until the weaning stage. At this age squab were ready and in prime condition for slaughter or were transferred to be reared further.
In both stages, the dietary ME levels were (2600, 2800 and 3000 Kcal) with protein level (14, 16 and 18%) Diets were formulated in mash form containing vitamin and mineral premix. During the stage 1 (growing period) the following measurements were recorded: initial body weight at 28-30 day of age, final body weight, daily feed intake, total feed intake per pair and mortality rate%. During the stage 2 (laying period) the following measurements were calculated: initial body weight, final body weight, daily feed intake per pair with or without squabs, total feed intake per pair with or without squabs, egg number, fertility, hatchability, squab production per pair, squab’s growth during 28-day, body weight of squabs at the end of 28-day, squab’s mortality and livability.
