Electrical field stimulation (EFS) induces frequency-dependent contractions of the longitudinal muscle of isolated quail rectum which were sensitive to tetrodotoxin. The aim of the present study was to investigate whether purinergic neurons are implicated in the response to nerve stimulation. arabic 18 English 103

ABSTRACT Background: The objective of this study was to evaluate changes of haematological and biochemical parameters in Hejazi goats under synchronization protocols treatment. Methods:Forty fertile and healthy female Hejazi goats were divided equally and randomly into four groups (n=10). All synchronization protocols started 7 days after the first 125 µg Cloprostenol injection (i.m.). The first group received CIDR treatment for 7 days only and followed by injection of second dose of PGF2α and 400 IU of PMSG, and the second group received CIDR treatment for 14 days and followed by injection of second dose of PGF2α and 400 IU of PMSG, and the third group received injection of 0.004 µg of synthetic GnRH analogue for 7 days and followed on day 14 by a second injection of 125 µg PGF2α followed by second injection of 0.004 µg of synthetic GnRH analogue, the fourth group received two doses of 125 µg PGF2α with14 days interval. Blood samples were collected from all of the does for biochemical analysis. Results: Observations showed no external or behaviour changes recorded and slight changes in all groups in diagnostic parameters. The conception rate tended to be decrease specific with increase in other days Conclusions: This study showed that monitoring the biochemical diagnostic parameters in the four groups going different protocols we didn’t record any significant different (P>0.05). The current study suggests that CIDR treatment for short and long are safe in Hejazi doe

Abstract The use of antibiotics as growth promotors to enhance animal production is banned in many countries around the world due to antimicrobial resistance. There is a need therefore, for new alternatives to antibiotics in medicine and veterinary medicine practices. The antibacterial activity of clove oil and some antibiotics were tested in vitro against three isolates of E. coli {1 avian pathogenic (E. coli 6.2) and 2 non-pathogenic (E. coli 6.1 and E. coli X)}, Salmonella enteritidis and Salmonella spp., by disk diffusion and minimum inhibitory concentration (MIC) methods. All bacteria tested showed intermediate susceptibility to clove oil using disk diffusion method except the non-pathogenic E.coli 6.1. The inhibition zones measured were 0mm, 12mm, 13mm, 15mm and 15mm for E. coli 6.1, E. coli 6.2, E. coli X, Salmonella enteritidis and Salmonella spp., respectively. E. coli 6.1 was resistant to Ampicillin, and Lincomycin with multi antibiotic resistance (MAR) index of 0.2. E. coli 6.2 was resistant to Ampicillin, Doxycyclin and Lincomycin with MAR index of 0.3. E. coli X was resistant to Ampicillin and Colistin with MAR index of 0.2. Salmonella enteritidis was resistant to Amoxycillin/Clavulinic acid, Ampicillin and Lincomycin with MAR index of 0.3. Salmonella spp was susceptible only to Neomycin but was resistant to 9 out of 10 antibiotics with very high MAR index of 0.9. The MICs of clove oil were 6.25mg/ml for the avian pathogenic E. coli and 3.12mg/ml for non-pathogenic E. coli and Salmonella spp. and 12.5mg/ml for Salmonella enteritidis. It is concluded that clove oil has promising antibacterial activity and more studies are needed to investigate its in vivo activity as alternative to antibiotics in poultry arabic 13 English 85
