Reduction of aflatoxin effects of quail.

A natural occuring outbreak of aflatoxicosis was observed in Bobwhite quail chicks while on a brooding experiment. A slight reduction in effects was noted for birds which received Tylan in the water from 0-3 days and Terramycin from 0-35 days of age. No symptoms of aflatoxicosis were observed in birds which received a product (FloxAid) containing two antibiotics and eight vitamins from 0-14 days. It is postulated that the primary mode of protection was via the water soluble vitamin D content of the product with possibly some protection from vitamins A, E and K.

Debeaking method for Bobwhite quail.

Four experiments were conducted to determine the suitability of various debeaking procedures for Bobwhite quail at hatching or at one week of age. Two experiments were conducted using a "precision" type debeaking method with the following treatments: control; debeaked at hatching with debeaker guide plate holes of 2.38 or 2.78 mm; debeaked at seven days of age using guide plate holes of 2.38, 2.78 or 3.18 mm. Two experiments tested a "touch-burn" method at hatching with the following treatments: control; burned 1/4 distance to nares; and burned 1/2 distance to nares. The "precision" type methods at hatching or seven days of aged reduced mortality from cannibalism; however, these methods were found to be relatively slow and difficult, and the birds lacked uniformity in beak and body size at five weeks of age. Burning 1/2 distance to nares was too severe, causing a reduction in body weight and poor feed efficiency. Burning 1/4 distanct to nares gave the most favorable results: growth and feed efficiency as good or better than controls, uniform birds and decreased cannibalism.
