“…The IOF of BCAAb not only affected survival and hatching success but also specific hatching events (internal and external pipping and hatching) due to the increased number of non-pipped dead embryos. As in the present study, Bhattacharyya et al (2018) reported that the IOF of amino acids in turkey eggs did not affect the rate of death after pipping. A higher number of dead embryos in the BCAA groups may be related to the high osmotic pressure of the injected solution, allergic cavities or the pure toxicity of the high amino acid levels concerned (Bhanja & Mandal, 2005;Bhattacharyya et al, 2018) or to injection sites and times (Ohta & Kidd, 2001;Kop-Bozbay & Ocak, 2015b).…”

The yolk and albumin of a fertile egg contain considerable amounts of amino acids for embryonic growth and development (Shafey et al, 2013(Shafey et al, , 2014.…”

“…At hatch, the poults and all unhatched eggs were counted, and subsequently, the poult quality scores (PQS, Tona et al, 2003) and hatching). In this examination, the dead poults were evaluated as poults fully formed but dead without pipping or as eggs pipped but poults dead in shell, and thus, they were classified as dead with pipping or dead without pipping (Bhattacharyya, Majumdar, Bhanja, Mandal, & Kadam, 2018). Dead poults in each class were expressed as the percentages of incubated fertile eggs.…”

In this study, the influence of a branched‐chain amino acid blend (BCAA composed of 3 l‐leucine:1 l‐valine:2 l‐isoleucine) injected into the amniotic fluid was evaluated for embryonic growth, yolk‐sac (YS) utilization and development of gastrointestinal tract (GIT) and skeletal muscles of turkey embryos from day 24 of incubation (24E) to hatching, together with hatchability, poult quality and liver L* (lightness), a* (redness) and b* (yellowness) values at hatch. At day 22 of incubation, embryonated eggs (n = 240) were assigned to three treatments, that is, eggs were not injected (control, NC) or injected with 1.5 ml sterile solution with 0.9% salt (SA) or 0.2% BCAA blend (BCAAb). These solutions were injected manually into the amniotic fluid of the embryonated eggs. To determine weights and lengths (where appropriate) of the studied organs and tissues, four embryonated eggs and poults per treatment were selected at 24E and at hatch. While the BCAAb decreased the YS and embryo weight, hatchability and the liver L* value, it increased the weight and quality of poults and the weights of breast and thigh muscles at hatch. In conclusion, the in ovo feeding of the BCAA blend negatively affected hatchability but positively affected hatching weight and poult quality by improving development of skeletal muscles and by regulating energy metabolism.

Background and AimIn the recent past,few studies have been carried out in chicken to assess the effect of Azolla meal and raw Azolla feeding on the performance of chicken. If turkeys effectively use unconventional feedstuffs like Azolla without reducing the performance, it will increase the profitability of turkey business. Hence, a study was carried out to evaluate the effect of dried Azolla pinnata vis-a-vis raw Azolla as choice feeding on the growth, feed conversion ratio (FCR), blood biochemical attributes, and immune competence traits of growing turkeys under intensive system.Materials and MethodsA total of 72, 8-week-old grower turkey poults of black variety were randomly distributed into three dietary treatments having three replicates each with eight birds. The birds of the control group (T1) were fed a basal diet (CP - 19.71% and ME - 2789.79 Kcal/kg), while the other group (T2) and choice-feeding group (T3) were fed 5% of basal diet replaced by dry Azolla powder on DM basis and ad libitumAzolla along with basal diet, respectively.ResultsThere was no significant difference among the different groups in the average weekly weight gain during the entire experiment. FCR was significantly better (p<0.05) in the choice-feeding group compared to the other two experimental groups during 8-16 weeks of age. There was no significant difference among the treatment groups in any of the blood biochemical indices except plasma uric acid, which was significantly decreased (p<0.01) in T2 compared to T1 at 16 weeks of age. HA and IgM response to 1% sheep red blood cells (log2 titer) were numerically better in T2 and T3 compared to the T1.ConclusionThus, it may be inferred that choice feeding with Azolla, and basal diet may improve FCR without any adverse effect on blood biochemical attributes and immune competence traits.

“…Embryonic development is affected by many factors, including egg nutrition, temperature, and humidity (Dymond et al, 2013;Noiva et al, 2014;Yildirim and Yetisir, 2004). Previous reports have indicated that the changes in egg nutrition affect the embryonic development and health (Bhattacharyya et al, 2018;Kermanshahi et al, 2017). Other researchers have shown that restricting maternal nutrition affects the development of embryos (Prezotto et al, 2016;Raja et al, 2016).…”

The objective of this study was to evaluate the effects of maternal dietary intake on the amino acid and fatty acid contents in eggs during the laying period. An experiment with a 2×2 factorial design was conducted with two maternal dietary intake levels (100 and 75% of dietary intake recommended by the Chinese Ministry of Agriculture) and two broiler lines (fat and lean line). A total of 384 hens of fat line and 384 hens of lean line at 23 weeks of age were included in the experiment. Each line was randomly divided into two treatments (n = 192 in each treatment, with 12 replications), and each replication included 16 birds. The treatments were LN (lean line and normal maternal dietary intake, n = 192), LL (lean line and low maternal dietary intake, n = 192), FN (fat line and normal maternal dietary intake, n = 192), and FL (fat line and low maternal dietary intake, n = 192). The amino acid and fatty acid contents in eggs were tested (50 weeks of age). The fat line had higher levels of arginine, aspartic acid, glycine, histidine, leucine, methionine, and threonine in the egg albumen than the lean line. Low maternal dietary intake increased the cystine deposition in egg yolks. There were interactions between maternal dietary intake and line on the deposition of trans-oleic acid, docosanoic acid, and total fatty acid in egg yolks. Low maternal dietary intake increased the deposition of tetradecenoic and linolenic acids and the ratio of total polyunsaturated fatty acids to total saturated fatty acid in egg yolks but decreased the deposition of docosanoic acid. Maternal dietary intake and line affect the amino acid and fatty acid profiles in eggs.
