THE EFFECT OF MANGANESE SOURCE ON NUTRITIVE AND BIOPRODUCTIVE INDICES AT BROILER CHICKENS
In this experiment we studied the effect of chelated manganese from phosphatic
glass soluble in acids, phosphatic glass semi soluble in water and phosphatic glass
soluble in water and inorganic salts (Mn SO4) on nutritive and bioproductive indices
at broiler chickens. Mineral premix, made on calcium carbonate differentiate by
manganese supplementation source, and was assured a level of 30.00 mg active Mn.
The experiment was carried out on 120 broiler chickens divided in four
experimental groups (CL-V1, EL-V2, EL-V3 and EL-V4), respectively 30 chickens
per group. The hybrid used was Ross 308. The manganase assurance from
phosphatic glass soluble in acids, phosphatic glass semi soluble in water and
phosphatic glass soluble in water determine a decrease of manganese content in the
poultry litter comparative with the manganese assurance from manganese sulfate.
The manganese assurance from phosphatic glass soluble in water determines the
increasing of the bioproductive indices with 5% comparative with the manganese
assurance from manganese sulfate
