“…In general, no differences in body weight gain, feed intake or feed to gain ratio were observed in slow-growing broilers from eggs injected the BCAA blend into different sites. These findings are agreement with a previous study (Bhanja and Mandal, 2005) using the BCAA blend in fast-growing broilers. The effect in ovo feeding on the poultry performance varies depending on many factors.…”

“…In our study BCAA injected into the amnion, yolk sac or albumin at 18 d of incubation did not, however, reduce hatchability or studied performance characteristics of birds. The disappearance between our study and previous studies (Al-Murrani, 1982;Ohta et al, 1999Ohta et al, , 2001) may be resulted in injection time (7 th vs. 18 th day of incubation), as reported by Bhanja and Mandal (2005). The albumen is transferred into the amniotic cavity and yolk sac (Ohta et al, 1999) after the second week of incubation.…”

“…These may be considered the content of in ovo solution, site of injection, line of breeders, breeding age, egg weight, the storage conditions for egg, hatchling's chronological and biological age and incubation conditions (Ohta and Kidd, 2001;Bhanja and Mandal, 2005;Shafey et al, 2012;Kop-Bozbay et al, 2013;Schulte-Drüggelte, 2015). The body weight at hatch, hatchability, FCR and GIT traits in the present study was comparable to that obtained by Bhanja and Mandal (2005), who used a mixture of leucine, isoleucine and valine of about 1.75:1.00:1.23 percent in amino acid injected birds. Likewise, Kita et al (2015) founded that there was no significant differences in body weight at hatch among in ovo injection of each BCAA.…”

“…It has been indicated that among BCAA, only leucine is capable of activating translation initiation factors and stimulating protein synthesis in skeletal muscles (Anthony et al, 2000). Thus, studies have focused especially on HMB (Foye et al, 2006(Foye et al, , 2007Tako et al, 2004) or BCAA (Bhanja and Mandal, 2005;Kita et al, 2015) supplementation in in ovo solution. However, leucine is not only a source for HMB formation, but also is an AA having extra proteolytic effects.…”

“…Therefore some studies were conducted to prefer the targeted injection site in embryonated eggs for to understand various physiological features associated with late embryonic development (Ohta and Kidd, 2001;Kop-Bozbay et al, 2013). It has been investigated the effect of the blend of BCAA (Bhanja and Mandal, 2005) or each of BCAA (Kita et al, 2015) on the hatchability traits and growth performance of fast-growing broilers. To our knowledge, the effect of in ovo administration of a mixture of BCAA (2 leucine: 1 valine: 1 isoleucine), which have an extra protein effect, into different sites of egg (amniotic cavity, yolk sac and albumin) on growth performance, carcass and some demand (muscle, blood etc.)…”

One hundred-fifty fertile eggs from 30-week-old Ross x Rhode Island Red (RIR) breeders as a factorial arrangement of 3 injection site (amnion, yolk sac or albumin) and 2 levels of BCAA (Control and BCAA, 0.2%) were arranged into 6 groups with 3 replicates. The solutions used in ovo feeding were aseptically prepared to contain 0% (C) or 0.2% BCAA (mixed within ratio of 2 L-leucine: 1 L-valine: 1 L-isoleucine) in 0.5% saline. At 18 d of incubation 1 ml of in ovo feeding solution was injected into the amnion (A), yolk sac (Y) or albumin (AL) of egg. Hence, there were six nutrition treatments; AC (n = 25), ABCAA (n = 25), YC (n = 25), YBCAA (n = 25), ALC (n = 25) and ALBCAA (n = 25). Upon hatch obtained birds were fed on standard broiler diets until slaughter (8 weeks of age). The YC had lower gizzard weight (P = 0.023) compared to other treatments. The interaction effect of factors on the gizzard weight was found significant (P < 0.025). The in ovo BCAA injection increased the gizzard weight of AL chicks while decreased that of A and Y birds. The crude fat content of thigh meat from Y birds was lower than those of A and AL broilers (P = 0.029). However, growth performance, muscles weights, digestive tract weight and length and abdominal fat, hearth, liver, weights are not affected by factors. The role of in ovo BCAA injection in slow-growing broiler needs further research.

BACKGROUNDN‐acetylglutamate (NAG) is the initial and essectial substrate in the process of de novo arginine synthesis, plays an important role in intestinal development. The aim of this study was to determine the effects of in ovo feeding of NAG, 1.5 mg/egg at 17.5 days of incubation (DOI) via amnion, on hatching performance, early intestinal histomorphometry, jejunal barrier, digestive function, and growth performance of broiler chickens between 1 and 14 days of age.RESULTSAmniotic injection of NAG had no significant effect on hatching characteristics compared with the non‐injected control group (NC group). Birds in the NAG solution‐injected group (NAG group) exhibited lower average daily feed intake and better feed efficiency during a period of 1–14 days. In comparison with the NC group, the NAG group had decreased crypt depth (CD) in the ileum and increased villus height (VH) / CD in the jejunum at 7 days, and decreased CD in duodenum and significantly increased VH in the jejunum at 14 days. However, the effects of in ovo supplementation with NAG on the density of goblet cells, and gene expression of mucin 2 and alkaline phosphatase were not significant. Chicks in the NAG group had a significantly higher mRNA expression level of trypsin and maltase in jejunum at 7 days than the NC group but not at 14 days.CONCLUSIONAmniotic injections of NAG (1.5 mg/egg) at 17.5 DOI could improve early growth performance of broilers during 1–14 days after hatching by accelerating the development of the intestine and enhancing jejunal digestive function. © 2023 Society of Chemical Industry.
