Beak trimming of turkeys. 2. Effects of arc beak trimming on weight gain, feed intake, feed wastage, and feed conversion.

چکیده
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 trial. Feed conversion was calculated as feed consumed divided by weight gained. Sex by beak trimming interactions were not found. Beak trimming reduced feed wastage of the two large-bodied strains, but did not affected feed wastage of the medium-bodied strain, which did not consume as much feed as the large-bodied strains. The results of this study support the hypothesis that beak trimming reduces feed wastage of large-bodied turkeys.

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...

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 ...

However, beak trimming is a painful procedure. There is a considerable body of morphological, neuro...
متن کاملThe effect of beak trimming on two strains of commercial tom turkeys. 2. Behavior traits.
The influence of beak trimming of two strains of commercial male turkeys (Strains A and B) on behavior during the growing period was investigated. Poults were either left with beaks intact or arc beak trimmed at hatching. Strain by beak treatment interactions were generally lacking, indicating that these two strains responded similarly. Beak trimming did not influence tameness (as measured by r...

Recently, toe trimming turkeys and broilers with a microwave technology has demonstrated reduced carcass tears and downgrading. Therefore, three Leghorn strains at 1d of age ...
