Impacts of In Ovo Feeding of DL-Methionine on Hatchability and Chick Weight

Abstract

The aim of this study was to determine the effect of in ovo DL-methionine injection into the fertile broiler eggs on hatchability and relative chick weight. In the trial, 132 fertile broiler eggs were obtained from a breeder flock (34-wk-old Ross 308 parent stock). Fertile eggs were randomly assigned to two experimental groups. Experimental groups were 1) Control 2) DL-methionine injected group with three replicates. Injections were carried out at the 16th day of incubation. At the end of the study, hatchability was 90.29%, and 84.74% in control and DL-methionine injected eggs respectively. Relative chick weights were 70.04% and 72.70% control and DL-methionine injected group respectively. At the end of the study, it determined that injection of DL-methionine increased 3.8% relative chick weight according to control. It suggested that DLmethionine may use as an in ovo feed additive for obtain heavier chick. Bu çalışmanın amacı döllü etlik piliç yumurtalarına in ovo DL-metiyonin enjeksiyonunun kuluçka randımanı ve civciv ağırlığına etkisini belirlemektir. Denemede 34 haftalık yaştaki Ross 308 ebeveyn hatlardan elde edilen 132 adet döllü etlik piliç yumurtası kullanılmıştır. Döllü yumurtalar iki deneme gruplarına tesadüfî dağıtılmıştır. Deneme grupları 1) Kontrol ve 2) DL-metiyonin enjekte edilen gruplardan ve üçer tekerrürden oluşturulmuştur. Enjeksiyonlar kuluçkanın 16. gününde uygulanmıştır. Çalışmanın sonunda, kuluçka randımanı kontrol ve DL-metiyonin enjekte edilen gruplarda sırasıyla %90,29 ve %84,74. Oransal civciv ağırlığı ise kontrol ve DL-metiyonin enjekte edilen gruplarda sırasıyla %70,04 ve %72,70 bulunmuştur. Çalışmanın sonunda DL-metiyonin enjeksiyonunun oransal civciv ağırlığını kontrol grubuna göre %3,8 arttırdığı belirlenmiştir. DL-metiyoninin kuluçkadan sonra daha ağır civciv elde etmek için in ovo besin maddesi olarak kullanılabileceği önerilmektedir.

Effect of in-ovo injection of glucose and egg white protein on the production performance and gut histomorphometry of broiler chicken

“…Similar findings were recorded by Foye et al, (2006) who found that in ovo injection of egg white protein and, HMB, carbohydrate increased hatch weight in broiler chicks. Similar results of improved hatch weight in broilers were reported by Isa Coskun et al, (2014).…”

Effect of in ovo feeding of β‐hydroxy‐β‐methylbutyrate on hatchability, muscle growth and performance in prenatal and posthatch broilers

“…This is in agreement with previous studies in that IOF of dextrin, l ‐arginine, vitamin C and grape seed extract improved hatchability. However, other results showed that IOF decreased or did not affect the hatchability. These variable results may be ascribed to different nutrients and injection techniques among studies.…”

Effect of arginine and threonine administered in ovo on digestive organ developments and subsequent growth performance of broiler chickens

“…Conversely, there are reports pointing out the reduced hatchability by Thr in ovo administration (Salmanzadeh et al., ). Generally, hatchability is affected by in ovo injecting site and time (Ohta and Kidd, ), depth of injection (Coşkun et al., ) and also type of injecting substance. As such, a possible explanation for contradictory results in the case of hatchability might be due to the combination of technical procedure and substance that used for in ovo injection.…”
