Physiologically Studied Appropriate Broiler Diets for Better Chicks

Patil Ajay Dadaji, Sakharam Balu Patil


The inclusion of low phytate grains in poultry diets will scale back the phosphorus (P) content of poultry feces; however their influence on fecal P composition isn't well established. To assess this, a hundred male broiler chicks (21 days old) were fed dietary treatments supported either a wild-type barley or one among 3 low salt mutant grains with 59, 62 & 99 reductions in phytate P, compared with the regular barley diet. The birds were housed in raised-floor battery cages with mesh grate floors above fecal collection trays with 4 birds per pen and 4 pens per treatment. The birds were fed for 9 days and faeces were collected twice every day throughout the last 2 days of the experiment. Total P concentrations were 10-20% lower in stool from birds fed low phytate barley diets compared with those fed the traditional barley diet. Phosphorus digestibleness increased (P = 0.05) as salt within the barley diet decreased. Phosphate was the main P fraction within the feces (69-75% extracted P) despite the sort of barley fed. Phytate constituted solely 3-12% of the P within the faeces, indicating its hydrolysis in the bird. Overall, these results recommend that feeding low-phytate barley diets will scale back P concentrations in poultry faeces while not inflicting vital changes in P composition.
