Comparison of beak-trimming methods on early broiler breeder performance.
Beak trimming is necessary in commercial broiler breeders to prevent or decrease trauma as they mature. Two common beak-trimming methods were evaluated by early performance comparison with nontrimmed chicks (NBT). The robotic electrocautery device (ECD) trims and cauterizes the beak tip. The robotic infrared beak-trimming device (IBT) applies an infrared light beam to destroy the live basal tis...
متن کاملBeak trimming of turkeys. 1. Effects of three methods of beak trimming on body weight and mortality of six genetic lines.
An experiment was designed to compare BW and mortality of turkeys when three methods of beak trimming were utilized. Turkeys from six genetic lines were assigned to three beak trimming methods: arc beak trimming at hatching, hot-blade block trimming at 13 d, or hot-blade top-beak-only trimming at 13 d. Beak trimming method influenced 8-wk BW of three lines of females, but did not affect female ...
متن کاملBeak trimming of turkeys. 2. Effects of arc beak trimming on weight gain, feed intake, feed wastage, and feed conversion.
An experiment was conducted to study the effects of arc beak trimming on feed consumption, weight gain, and feed wastage in males and females from two large-bodied strains and one medium-bodied strain of turkeys. Birds were placed in wire-floored battery cages from 3 to 8 wk of age and feed intake, weight gains, and feed spilled into dropping pans were recorded for each of the 5 wk of each tria...
متن کاملBeak-Trimming Methods and their Effect on the Performance of Japanese Quail Pullets (Coturnix japonica)
This study aimed at verifying if beak-trimming methods in Japanese quail pullets could optimize production by decreasing stress caused by cannibalism. A total number of 816 day-old Japanese quails was distributed in a completely randomized experimental design in a 2 x 3 factorial arrangement, with two beak-trimming ages (14 and 21 days of age) and three beak-trimming sizes (not trimmed, 1/3 tri...
متن کاملDifferent effects of infrared and one-half hot blade beak trimming on beak topography and growth.
This study examined the effects of infrared beak treatment (IR-BT) and hot blade beak trimming (HB-BT) on beak length and production in laying hen pullets. Seventy-two 1-d-old birds were randomly assigned to the HB-BT, IR-BT, or control group. Birds were pair housed by treatment, and beak images and production indices were obtained posttreatment at fixed intervals for 10 wk. Immediately after t...
