Abstract:
Viral read presence in quail samplesEarly production performance of the Korea quail and the Chinese recessive white feather quail was studied.The results showed that the growth rate of three strains was not significant defference(P0.05),the Chinese recessive white feather quail was relatively slower than the other two.The Feed coversion efficiency of the Korea quail was lower than that of the Chinese recessive white feather quail,without significant defference(P0.05).The early mortality of the Chinese reccssive white feather quail was higher.Providing the three strains start to lay the first egg at the same age,the feeding cost before the laying period of the Chinese recessive white feather quail was less than that of the Korea quail.

Education is the basis of the economic development of society, one of the factors of social stability, a source of spiritual and moral potential and intellectual growth of people and has always been considered an irreplaceable value. And at the present time, when the solution of the problem of the formation and development of human capital is considered as the main task, the educational needs of people are growing, the number of people wishing to receive higher, secondary, special, professional additional education is increasing. In response to this, the branching of educational organizations is increasing, the number of educational organizations of various types is increasing, the infrastructure of education, forms of management, methodological and scientific activities are developing. Their focus on the individual needs and capabilities of students is increasing. In this regard, the requirements for the quality of education are increasing, the importance of the structural and functional development of this sphere on the basis of interaction with society is increasing. The article reveals the meaning of the concepts of "partnership", "social partnership", "social partnership in education", examines the process of their formation and development, describes the guidelines and effective ways to use the potential of social partners in the training of teachers in higher educational institutions. Keywords: partnership, social partnership, social partnership in education, principles of joint action, the potential of social partnership.

The authors determined whether results of experiments on copulatory and affiliative behavior of pairs of Japanese quail (Coturnix japonica) conducted in a closely confining apparatus would predict behavior in a large enclosure in which female quail could avoid contact with male quail. As found previously in studies of closely confined quail, in a large enclosure containing numerous barriers, both unmated female quail and mated female quail laying unfertilized eggs were more likely to remain near a confined male quail than were mated female quail laying fertilized eggs. Furthermore, the number of copulations that a pair engaged in when closely confined predicted the number of copulations that they engaged in when they were in the large enclosure. Patterns of affiliation and of mating in a confining laboratory apparatus thus predicted behavior in a larger enclosure that provided female quail with opportunity to avoid contact with male quail.

The present study makes an investigation into expression of genes related to cardiac development in chicken, quail and chicken-quail hybrids during the early stage of embryogenesis. Real-time PCR was used to detect mRNA expressions of Nkx2-5, GATA4 and TBX5 in the heart of chicken, quail and chicken-quail hybrids embryos during the 3rd to 7th days of incubation. Results showed that NKX2-5 mRNA displayed a similar expression trend in chicken, quail and chicken-quail hybrids. The initial and highest expression of Nkx2-5 was focused on the 3rd day of incubation, then it declined till 5th day of incubation, thereafter, it fluctuated. Expression of Nkx2-5 gene in quail was significantly higher than in chicken and chicken-quail hybrids, and no significant difference was observed between the two latter species. GATA4 mRNA showed a similar expression trend between chicken and quail, which displayed a steady increase from 3rd to 6th d, then, the expression level decreased. However, GATA4 mRNA expression in chicken-quail hybrids was significantly higher than that in chicken and quail from 3rd to 5th d (p<0.01), but significantly lower than that in chicken and quail during the later stage of the experiment (p<0.05), due to the dramatic drop from 5th d onwards (p<0.01). TBX5 mRNA expression in chicken and quail showed the same trend as GATA4 expressed in the two species. Furthermore, TBX5 expression in chicken-quail hybrids was significantly higher than that in chicken and quail during the whole course of experiment, although relatively lower TBX5 expression was detected in the early stage. In conclusion, Nkx2-5, GATA4 and TBX5 genes showed dynamic changes during the process of cardiac development in chicken, quail and their hybrids embryos. In addition, the expression trend in chicken was similar to that in quail, and there was no significant difference for gene expression level, except NKX2-5. However, expression of these genes in chicken-quail hybrids was significantly different from their parents, the difference mechanism needs to be further explored.

Abstract The behavior of quail primordial germ cells (PGC) after injection into chick embryos by the intravascular route was examined. The quail (donor) PGC, taken from the bloodstream of quail embryos (recipient) at stage 13–14, were injected into the vitelline vessels of chick embryos (recipient) at stage 15. In the recipient embryos, the PGC of the quail and the chick were histochemically distinguished by a double‐staining technique involving a lectin, from Wistaria floribunda (WFA) and the PAS reaction. One day after injection, quail PGC appeared in the prospective gonadal region of recipient chick embryos, being localized among the recipient chick PGC. This result indicates that a staining technique specific for WFA lectin is useful for identification of quail PGC and that quail PGC can be transferred by a vascular route for the production of germline chimeras. © 1992 Wiley‐Liss, Inc.

The effects of retinoic acid on the development of reproductive organs and egg production in female Japanese quail (Coturnix coturnix japonica) were investigated. Female quail were fed a diet containing retinoic acid at 4 mg/kg (RA) or two diets containing retinyl acetate at 5000 IU/kg (VA1) or 14 000 IU/kg (VA2) after being fed a vitamin A-free diet for 2 wk (experiment 1). The oviduct and ovary grew more rapidly (P < 0.05) in RA-treated quail than in VA-treated quail at 5 wk of age. In addition, the body weight of RA-fed quail was also greater (P: < 0.05) than that of VA-fed quail at 5 wk. The RA-treated quail laid their first eggs approximately 5 days earlier (P < 0.05) than the VA-treated quail. Furthermore, these RA-fed quail laid more eggs (P < 0.05) than those VA-fed quail during the experimental period. To confirm the results of experiment 1, a similar experiment was conducted to record the first egg and total eggs laid by quail fed VA2 or RA (experiment 2). The early onset of oviposition was again observed in the RA-treated group (P < 0.01). These results suggest that retinoic acid has a stimulating effect on the reproductive system of female Japanese quail, as has been previously shown in the reproductive system of male Japanese quail.

The distribution and behavior of chick primordial germ cells (PGC) injected into quail embryos were examined. PGC from chick embryos at stages 13-14 were injected into the blood stream of quail embryos at stages 15-20. After one day, the quail embryos were examined histologically. The chick PGC in the quail embryos could be readily identified by the histochemical PAS technique, whereas quail PGC were never stained by PAS. When the chick PGC were injected into the quail embryos during stages 15-18, they appeared mostly in the gonadal region of the recipient quail embryos. A few PGC were found at extragonadal sites. When the chick PGC were injected into the quail embryos at stages 19-20, in which the PGC of the recipient quail embryos had finished their migration into the gonads, most of the donor chick PGC were found at ectopic sites, in the head, trunk and limbs. These results indicate that most of the chick PGC, injected at the earlier stages 15-18, migrated to the gonadal anlagen of the recipient, while following later injection (from stage 19), most of the chick PGC migrated to ectopic sites.

Eggs laid by 1 5 3 Gd-labeled Japanese quail were collected each day for 24 days. Maximum transference of the lanthanide to an oocyte approximated 27% of the dose given the quail and occurred usually for the egg collected on the third day. The 24 largest oocytes from each of 2 quail were removed 18 hr after labeling the quail. The curve for a plot of percent 1 5 3 Gd vs. gram of oocyte for these 24 oocytes approximated a log-log function. Eggs doubly-labeled with 1 5 3 Gd and Sudan black B showed no label in the latebra. Quail hatched from labeled eggs were dissected at various times up to 67 days of age. The percent of egg 1 5 3 Gd that was found in the F1 quail decreased from 100% to approximately 55% during the first 14 days. The percentage recovery for mature quail was 55.8%. The major portion of the 1 5 3 Gd present in each F1 quail was found in the yolk sac and ranged from 96.0% for hatchlings a few hours old to 73.3% for mature quail. The weight of the yolk sac decreased from .7g for hatchlings to .04g for mature quail. The first 5 eggs laid by producing F1 quail contained a total of .643% of the 1 5 3 Gd in these quail. The graph curve for these eggs for percent 1 5 3 Gd vs. day of collection approximated an exponential function, in contrast to the marked maximum seen for 1 5 3 Gd levels in eggs laid by the parent quail.
