[Objective] This study aimed to make a survey of domestic pigeons for infection with Eimeria species of coccidia was conducted in Guangdong Province, southern China. [Method] A total of 244 fecal samples(102 from Huizhou, 83 from Jiangmen, 35 from Chaozhou and 24 from Guangzhou, respectively) in four pigeon breeding farms between June 2012 and March2013 were collected and examined microscopically. [Results] Eimeria oocysts were seen in 223(91.4%) fecal samples, with three species, namely E. labbeana, *** and E. kapotei. E. labbeana was the most common species in Guangdong provinces with an overall prevalence of 91.4%, while a slightly lower incidence of E. columbae and E. kapotei species was detected with11.1% and 6.6%, representatively. The prevalence in different months varied ranging from 83.3% to 91.7%, with the highest prevalence in summer. Nestling groups showed obviously high infection than adult pigeons. [Conclusion] The present survey indicated the wide and severe prevalence of Eimeria infection in Guangdong domestic pigeons, which suggested that integrated measures should be taken to control and prevent coccidiosis of pigeons in this province.

The objective of this study was to investigate the relationship between gene expression of nutrient（amino acid, peptide, sodium and proton） transporters in the small intestine and embryonic growth in domestic pigeons（Columba livia）. One hundred and twenty-five fertilized eggs were randomly assigned into five groups and were incubated under optimal conditions（temperature of 38.1 °C and relative humidity of 55%）. Twenty embryos/birds from each group were sacrificed by cervical dislocation on embryonic day（E） 9, 11, 13, 15 and day of hatch（DOH）. The eggs, embryos（without yolk sac）, and organs（head, brain, heart, liver, lungs, kidney, gizzard, small intestine, legs, and thorax） were dissected, cleaned, and weighed. Small intestine samples were collected for RNA isolation. The m RNA abundance of intestinal nutrient transporters was evaluated by real-time reverse transcription-polymerase chain reaction（RT-PCR）. We classified these ten organs into four types according to the changes in relative weight during embryonic development. In addition, the gene expression of nutrient transporters was differentially regulated by embryonic day. The m RNA abundances of b^0,＋AT, EAAT3, y^＋LAT2, Pep T1, LAT4, NHE2, and NHE3 increased linearly with age, whereas m RNA abundances of CAT1, CAT2, LAT1, EAAT2, SNAT1, and SNAT2 were increased to higher levels on E9 or E11 and then decreased to lower levels until DOH. The results of correlation analysis showed that the gene expressions of b^0,＋AT, EAAT3, Pep T1, LAT4, NHE2, NHE3, and y^＋LAT2 had positive correlations with body weight（0.71〈correlation coefficient（CC）〈0.82, P〈0.0001）, while CAT1, CAT2, EAAT2, SNAT1, and SNAT2 had negative correlations with body weight（-0.86〈CC〈-0.64, P〈0.0001）. The gene expressions of b^0,＋AT, EAAT3, LAT4, Pep T1, NHE2, NHE3, and y^＋LAT2 showed positive correlations with intestinal weight（0.80〈CC〈0.91, P〈0.0001）, while CAT1, CAT2, and EAAT2 showed negative correlations with intestinal weight（-0.84〈CC〈-0.67, P〈0.0
