“…Threonine content is relatively high in immunoglobulins (Tenenhouse and Deutsch, ), and thus, in ovo administration of threonine may have caused greater immunoglobulin synthesis. In the current study, it is agreed that jejunum IgA has a specific requirement for THR; this means that a very high THR is required for gut function which was also observed in previous work (Kermanshahi et al., ) in our laboratory where in ovo injection of threonine in quail eggs increased mucin2 gene expression, while had no effects on digestive enzymes.…”

The objective of this study was to investigate the effect of in ovo injection of threonine (THR) on immunoglobulin A (IgA) gene expression of Japanese quail on hatch day. A total of 540 Japanese quail eggs were assigned into nine groups of 60 each and were set in a single-stage incubator. Treatments were as follows: non-injected (control), two diluent levels (0.05 or 0.1 ml saline), two sites of injection (in or under the air sac) and with or without nutrients (0.5 mg/ml THR). Eggs were injected on d 11 of incubation. On hatch day, after euthanizing hatched quail chicks, the intestine was removed and the jejunum was separated. The relative mRNA expression of jejunal IgA increased (p < 0.05) by the injection of 0.05 ml THR under the air sac when compared to the control group or other treatments of injection. Compared to the control group, no differences were imputable to treatments of 0.1-ml injections on IgA gene expression. Differences with other injected groups were not significant. It was concluded that injection of 0.05 ml saline containing 0.5 mg THR/ml under the air sac can improve jejunal IgA mRNA expression in newly hatched Japanese quail chicks.

“…Room temperature was maintained at 32°C during the first week and gradually decreased by 3°C weekly until 22°C, and then maintained constant until the end of the experiment (Khaksar et al, 2012). The quails were subjected to continuous lighting program of 23L:1D during the entire experiment (Kermanshahi et al, 2015).…”

KeywordsGrowth performance, Japanese quails, native lactobacilli, serum biochemical parameters. ABStRACtThe objective of the present study was to evaluate the probiotic effects of different concentrations of four selected native Lactobacillus strains on the growth performance and serum biochemical parameters of Japanese quails. A completely randomized design (CRD) was applied, including seven probiotic treatments with four replicates of 20 quails each, totaling 560 quails. Treatments were applied for five weeks. Four native Lactobacillus strains were anaerobically grown in a 10-L batch fermenter and lyophilized (10 10 CFU/g). Treatments were as follows: T1: control (basal diet); T2: commercial probiotic CP1; T3: commercial probiotic CP2; and T4, T5, T6, and T7: four native strains added at levels of 50, 100, 150, and 200 g/ton diet, respectively. The native probiotics significantly improved body weight gain (BWG) and feed conversion ratio (FCR) during the starter, finisher, and overall periods (35 days) (p<0.05), whereas no significant effect was observed on feed intake. The native strains significantly influenced the serum glucose, total protein, globulin, phosphorus, uric acid, low-density lipoprotein (LDL), LDL/HDL ratio, white blood cell counts (WBC), and mean corpuscular hemoglobin concentration (MCHC) of quails during the rearing period (p<0.05), whereas treatments had no influence (p>0.05) on blood cholesterol, calcium, high-density lipoprotein (HDL), or hemoglobin (HB) levels or on red blood cell counts (RBC). The cecal and small intestine samples of the quails fed the native Lactobacillus strains contained significantly higher Lactobacillus spp. and lower E. coli populations compared with the control diet and those supplemented with commercial probiotics. It was concluded that the use of the native Lactobacillus strains (150 g/ ton diet) promoted the best performance of Japanese quails.

“…The in-ovo method was first used by Sharma & Burmester (1982) for the vaccination of turkey hatching eggs against Marek's disease. Recently, the in-ovo method has been investigated by researchers for administering ascorbic acid (Elibol et al, 2001;Ipek et al, 2004;Sgavioli et al, 2015), carbohydrates (Zhai et al, 2011;Salmanzadeh, 2012;Ipek et al, 2004;Tako et al, 2004), amino acids (Bhanja et al, 2014;Ohta et al, 1999;Kermanshahi et al, 2015), vitamins (Bello et al, 2013;Salary et al, 2014), minerals (Yair et al, 2013;Oliveira et al, 2015), pollen (Coskun et al, 2014), hormones (Moore et al, 1994;Kocamis et al, 1999), and royal jelly (Moghaddam et al, 2014).…”

KeywordsIn-ovo feeding, propolis, hatching traits, quail.Submitted: August/2016 Approved: September/2016 ABSTRACT The purpose of this study was to determine the effects of in-ovo injection of a propolis water extract on hatchability, embryonic mortality, starter live performance, and livability of Japanese quails. In total, 500 fresh hatching eggs were randomly distributed into five treatment groups of 100 eggs per treatment with four replicates of 25 eggs each. On day 14 of incubation, eggs from group 1 were not injected (control), group 2 was injected with distilled water (water), group 3 was injected with 1% propolis water extract (1% propolis), group 4 was injected with 2% propolis water extract (2% propolis), and group 5 was injected with 3% propolis water extract (3% propolis). A completely randomized design was applied, and data were analyzed using the least-square methodology. Hatchability and embryonic mortality in the 2% propolis and 3% propolis treatment groups were significantly lower compared with the control group, but no significant differences were observed between the 1% propolis and control groups. There were no significant bodyweight gain, feed intake, feed conversion ratio, or livability differences among treatments. The results of this study demonstrated that in-ovo injection of propolis water extract, especially at doses of 2% and 3% propolis, had negative effects on hatchability and embryonic mortality, but 1% propolis had no detrimental effects on hatchability or embryonic mortality. In all treatment groups, propolis did not negatively affect body weight gain, feed intake, feed conversion ratio, or livability.
