“…In ducks it has been shown that post hatching parental care is regulated by high levels of prolactin (Boos et al 2007), which in turn seems to have a genetic basis in geese (Jiang et al 2009). Future common garden experiments could elucidate whether this change in parental care is caused by phenotypic plasticity or evolution.…”

The optimal duration of parental care is shaped by the trade-off between investment in current and expected future reproductive success. A change in migratory behaviour is expected to affect the optimal duration of parental care, because migration and non-migration differ in expectations of future reproductive success as a result of differential adult and/or offspring mortality. Here we studied how a recent emergence of nonmigratory behaviour has affected the duration of parental care in the previously (until the 1980s) strictly migratory Russian breeding population of the barnacle geese Branta leucopsis. As a measure of parental care, we compared the vigilance behaviour of parents and non-parents in both migratory and non-migratory barnacle geese throughout the season. We estimated the duration of parental care at 233 days for migratory and 183 days for non-migratory barnacle geese. This constitutes a shortening of the duration of parental care of 21% in 25 years. Barnacle geese are thus able to rapidly adapt their parental care behaviour to ecological conditions associated with altered migratory behaviour. Our study demonstrates that a termination of migratory behaviour resulted in a drastic reduction in parental care and highlights the importance of studying the ecological and behavioural consequences of changes in migratory behaviour and the consequences of these changes for life-history evolution.

“…P rolactin (PRL) is one of the hormone family that includes growth hormone (GH), placental lactogen (PL), and somatolactin (Power, 2005). It is a polypeptide hormone which synthesized and secreted by the animal's anterior pituitary gland (Jiang et al, 2009) and playing an essential role in regulating reproduction and lactation in mammals (Bonomo et al, 2007).…”

Broodiness is a behavioral trait observed in most common breeds of domestic fowl and due to its fundamental role in avian reproduction, it has been of great interest to poultry scientists, breeders and producers of hatching eggs. Prolactin gene (PRL) is generally accepted as crucial to the onset and maintenance of broodiness in birds and thus plays a crucial role in egg production. Therefore, the present study aimed to screen the Single Nucleotides Polymorphisms (SNPs) of prolactin gene in four commercial chicken lines namely Hubbard F15, Lohmann, Cobb500, and Avian48 using PCR and direct sequencing. A total number of forty chickens (ten females from each of the four commercial chicken lines) were used. Blood samples were collected aseptically from brachial (wing) vein of the chickens for genomic DNA extraction. PCR reaction was done using five pairs of primers, one sense (F) and one antisense (R) primer for each of the five exons of prolactin gene. Finally, DNA sequencing and Single Nucleotide Polymorphisms (SNPs) analysis was done using Laser gene Megalign program. The results showed three SNPs in Hubbard F15 chicken line; one synonymous SNP at the position 3838 bp (ACC/ACT-transition) in exon 2 while in exon 5, two SNPs were detected; one non-synonymous single nucleotide polymorphism at the position 7921bp (CCT/TCT-transition) which results in amino acid changes at codon positions 169 (P/S), and one synonymous single nucleotide polymorphism at the position 8187 bp T/ C. The study concluded that this SNP in PRL gene could be used as the potential molecular markers for egg production traits in chicken.

“…Three mutations screened (C-1607T, C-5749T and T-5821C) by Liu et al (2007) showed that there is a correlation between different haplotypes and egg production. In geese, three SNPs (A-401G, G-268A and T-266A) in the 5'-proximal region of PRL gene have been screened and statistical analysis suggested that these polymorphisms have the potential to be utilized in molecular breeding for egg production (Jiang et al, 2009). All the above studies displayed that PRL is an important candidate gene on egg production.…”

As a candidate gene related to egg production, prolactin plays a crucial role in the reproduction of birds. In this study, polymorphism of the prolactin gene was screened in six Chinese native duck breeds (Shanma, Shaoxing, Youma, Jinyun, Jingjiang and the F 2 resource population of white Liancheng X white Kaiya) using PCR-SSCP and direct sequencing. The results showed that 12 SNPs were detected: C-213T in the 5 flanking region, A-1842G in exon 2, A-3869G in exon 4 and C-5961T in exon 5, T-295C, C-381A and A-412G in intron 1, T-2231C in intron 2, C-3949T, T-3988G and T-4009C in intron 4 and T-6052A in the 3 flanking region. The C-381A site and C-5961T site can be detected by XbaI and Pst1 PCR-RFLP, respectively. Furthermore, the C-5961T mutation results in an amino acid conversion (Cys to Arg) in the functional domain and affects the existence of a heparin binding site (L-R-R-D-S-H-K). In the F 2 resource population, association analysis demonstrated that the C-5961T polymorphism was significantly associated with egg production and egg weight, with the CC genotype associated with higher egg production and bigger egg weight than the CT genotype.
