“…In all evaluated weeks, the birds subjected to laser beak trimming were heavier (p<0.05) compared with those subjected to conventional beak trimming with hotblade. This result is consistent with the findings of Dennis & Cheng (2010), who reported lower body weight in 5-to 35-wk-old layers submitted to hotblade compared with laser beak trimming.…”

“…Beak-trimming method significantly influenced weight gain in all weeks evaluated, with higher values (p<0.05) observer in laser beak-trimmed birds ( Figure 1). This result is consistent with the findings of Dennis and Cheng (2010), who determined higher body weight in 10-wk-old layers submitted to laser beak trimming. During the period of 9-12 weeks of age, hot blade beak-trimmed birds presented higher weight gain (p<0,05) than laser beak-trimmed ones.…”

“…According to Dennis & Cheng (2012), birds submitted to laser beak trimming present higher weight gain because this technique causes less pain and the shape of the remaining beak allows the performance of natural feeding behavior. Hot-blade beak trimming causes chronic pain, leading to reduced feed intake, and consequently, poor body development (Dennis & Cheng, 2010). Dennis et al(2009) compared hotblade and laser beak trimming in brown semi-heavy layers, and did not find any weight gain differences at 30 weeks of age, demonstrating the applicability of laser beak trimming.…”

Laser beak trimming is a promising alternative to conventional hot-blade beak trimming as it is less painful and provides better beak uniformity and better animal welfare. In this study, laser vs. hot-blade beak trimming were compared in 400 Hy-line Brown pullets between 2-16 weeks of age. At 7 days of age, birds were distributed according to a completely randomized design into two treatments, with 10 replicates (pens) of 20 birds each. Birds and feed offer and residues were weekly weighed to determine weight gain, feed intake, and feed conversion ratio. In weeks 4, 8, 12, and 16 weeks, one bird per experimental unit was sacrificed to measure the development of the heart development, liver, proventriculus, gizzard, small intestine, and bursa. And of the oviduct in week 16. Pullers submitted to laser beak trimming presented higher weight gain and weekly feed intake, and better feed conversion ratio during the evaluated period. There was no influence of beak trimming methods on the development of the digestive organs, bursa or oviduct. Laser beak trimming can be used as an alternative to hot-blade beak trimming of commercial brown layers.

“…Ao se comparar a debicagem com lâmina quente ao tratamento por radiação infravermelha, em aves da linhagem Bovans White, constatou-se que o método alternativo de debicagem proporcionou redução da agressividade e melhores condições de empenamento (Dennis & Cheng, 2010). As aves tratadas pelo método de radiação infravermelha gastaram menos tempo se alimentando e apresentaram maior massa corporal, em comparação às aves debicadas por lâmina quente.…”

Resumo -O objetivo deste trabalho foi avaliar o efeito da debicagem, por meio de lâmina quente ou por radiação infravermelha, sobre os indicadores produtivos e de qualidade de ovos, em três linhagens de galinhas poedeiras na primeira semana de vida, e se uma segunda debicagem seria necessária na décima semana de idade. As aves foram distribuídas em um delineamento inteiramente ao acaso, em arranjo fatorial 2x3x2 (primeira debicagem por meio de radiação infravermelha ou por lâmina quente x linhagens Lohmann LSL, Hy-line W-36 e Lohmann Brown x com ou sem debicagem à décima semana de idade), no total de doze tratamentos, com seis repetições. A debicagem por radiação infravermelha, na primeira semana de vida, proporciona os mesmos resultados produtivos e de qualidade dos ovos que o método convencional por lâmina quente. Não houve mortes por canibalismo em aves das três linhagens que não foram submetidas à segunda debicagem, mas se observou decréscimo de 8% da viabilidade, em aves à 63.ª semana de idade.Termos para indexação: bem-estar, produção de ovos, radiação infravermelha, tratamento de bico. Production index and quality of eggs of laying hens subjected to different methods of beak trimmingAbstract -The objective of this work was to evaluate the effect of beak trimming, by hot blade or infrared radiation, on the production indicators and egg quality of three laying hen strains in the first week of life, and whether a second beak trimming would be necessary in the tenth week. Birds were distributed in a completely randomized design with 2x3x2 factorial arrangement (first beak trimming by means of infrared radiation or hot blade x the strains Lohmann LSL, Hy-line W-36, and Lohmann Brown x with or without beak trimming at the tenth week of age), totaling twelve treatments with six replicates. Beak trimming by infrared radiation, in the first week of life, provides the same production results and egg quality as the conventional method by hot blade. There were no deaths from cannibalism for birds of the three strains that were not subjected to the second beak trimming; however, a decrease of 8% viability was observed in birds at the 63 th week of age.

“…The fact that the birds are debeaked and the type of debeaking affects the zootechnical indexes and the quality of the eggs (Mertens et al, 2009;Dennis & Cheng, 2010) makes the technique used to be extremely important (Vieita Flho et al Al., 2016). According to the above, the study aimed to evaluate three different methods of debeaking in relation to the zootechnical performance and its consequence on egg quality.…”

Among the several factors required in breeding laying hens, debeaking is a factor that interferes with batch performance and affects animal welfare. Thus, the objective of this study was to evaluate three different debeaking procedures and to verify the best technique to be used. For this, the performance of the birds, the incidence of cannibalism, and in rearing phase, the quality of the eggs were evaluated. Dekalb White birds were distributed in a completely randomized design with three treatments, T1 (infrared radiation debeaking) T2 (hot blade debeaking) and T3 (V debeaking).The data was submitted to Analysis of Variance and compared by Tukey's test (95%), using statistical software R. The frequencies of mortality and cannibalism were submitted to the ChiSquare test (Software R). It was observed that mortality was lower with IR debeaking in the breeding phase. Already in the rearing phase, the mortality was similar between the debeaking techniques and the cannibalism was null. The final mean weight (g), mean weight gain (g) and average daily weight gain in the rearing and egg quality variables were higher for V debeaking when compared to other techniques. It is concluded that V-debeaking provides better bird performance, resistance and shell thickness when compared to the infrared radiations and hot blade debeaking, in addition to subjecting the birds to less stress.
