Effect of magnetically treated water on some productive and reproductive performance in Egyptian geese
|
|
Abstract: The experiment was performed to study the influence of type water such as tap water (TW) and well water (WW) and exposed to magnetic field (approximately 4000 gauss) on productive and reproductive performance of Egyptian geese. The experiment was investigated in 2 × 2 factorial experimental design. A flock of 108 one year-old Egyptian female geese were utilized in this investigation. Birds were randomly divided into four equal groups, each made up of three replicates of 9 geese. The treatments included TW supplemented without or with magnetic exposure (TW vs. MTW) for 1st and 2nd treatment and also the same procedure was done for the well water (WW vs. MWW) for 3rd and 4th treatment. During the experiment, laying birds of the all group was kept in intensive system which confinement in a house and fed a commercial feed ad libitum. Natural mating was practiced during the experimental period from November to the end of May. The mean results showed that:
1-Magnetic treatment induced greater effect on WW than that on TW in terms of pH, conductivity, salinity, calcium, magnesium, total hardness and dissolved oxygen.
2-The response criteria were productive and reproductive performance as egg number, egg weight, egg mass, feed conversion ratio, fertility, hatchability, egg quality traits, blood biochemical, hormone levels and growth of gosling up to 20 weeks of age.
3-Geese drank WW decreased (P≤0.05) function of the renal and liver, plasma estrogen and progesterone and total antioxidant capacity, but increased thiobarbituric acid-relative substances.
4- Geese drank water exposed to the magnetic field increased (P≤0.05) egg number, egg weight, egg mass, water consumed, fertility, hatchability, number of gosling at day-old, shell weight and thickness, yolk weight, body weight gain for gosling up to 20 weeks of age and quantity of meat produced per geese per year compared to those of geese drank un magnetized water.
5-Geese drank water exposed to the magnetic field improved (P≤0.05) renal function (urea and creatinine), liver enzyme (AST and ALT) and reproductive hormones (estrogen and progesterone) of geese compared to those drank unexposed water.
6- Gosling drank magnetic water during 4-20 weeks of age significantly (P≤0.05) increased body weight gain, meat quantity produced per geese per year and water consumed but mortality rate and feed intake decreased, and feed conversion ratio was significantly improved.
In conclusion, exposing of water and practically well water to a magnetic field may offer a solution to improve productive and reproductive performance and antioxidant status of Egyptian geese and their offsprings. This treatment may be useful management practice in the area where geese breeders depends on well water as a sole source of drinking water.
Key words: Geese, magnetic water, productive and reproductive, hormone levels and antioxidant enzymes.
