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

Background: Whole muscle meat, meat products, and seafood contain different nutrients in adequate quantity providing a better environment for presence and replication of different microorganisms. There are underreported and inaccurate estimations of foodborne diseases due to the lack of effective surveillance systems in Libya. Aim: To determine the extent of microbiological contamination of whole muscle meat, meat products, and seafood. Methods: A total number of 731 samples of retail meat were collected from different stores in four cities in Libya. Samples were analyzed for aerobic plate count and subjected to microbiological enumeration and isolation techniques, followed by molecular identification by PCR and partial sequencing of 16S rDNA. Results: The results showed contamination of samples with enteric and spoilage bacteria. Fifteen genera of spoilage bacteria yielded 149 isolates which were detected and identified by PCR and partial sequencing of 16S rDNA as: Proteus spp., Provedencia spp., Raouttella ornithinolytical, Citrobacter spp., Enterobacter spp., Morganella morgi, Shewanella algea, Rhodobacter capsulatus, Listonella pelagia, Kluyvera spp., Pectobacterium spp., Brenneria spp., Klebsiella spp., Acintobacter radioresistens, and Pantoea spp. While for pathogenic bacteria, 143 isolates distributed among nine genera were identified by PCR and partial sequencing of 16S rDNA as: Bacillus spp., Escherichia spp., Shigella spp., Enterococci spp., Cronobacter spp., Staphylococci spp., Salmonella spp., Aeromonas spp., and Vibrio spp.. Many isolated bacteria are zoonotic bacteria with high importance for public health. Conclusion: Excessive handling and processing of meat and meat products seems to be one of the poorest microbiological qualities. These findings ought to be helpful in risk assessments and quality assurance of meat in order to improve food safety.

Natural products including alkaloids from algae may provide alternative source for new natural antioxidants due to their novel structure. In the present study the antioxidant properties of alkaloids extracted from Sargassum hornschuchii and Cystoseira compressa were assessed using various in vitro systems including 1,1-diphenyl-2-picrylhydrazyl (DPPH), superoxide, hydroxyl radicals, nitric oxide (NO) scavenging, phosphomolybdenum reduction and reducing power activity at different concentrations (6.25 to 100 mg/ml). The results showed that alkaloids rich extracts exhibit antiradical activity and reduction ability in concentration dependent. Extracts exhibit significant low scavenging activity on DPPH and nitric oxide radical activity Investigation … Rabia Alghazeer et al. compared to standard, ascorbic acid and butylated hydroxyanisole (BHA). Reducing power and total antioxidant of extracts showed less effect compared to standard, ascorbic acid and butylated hydroxyanisole (BHA). Superoxide, and hydroxyl radical assays showed a comparable scavenging activity compared to its standard. Therefore, new separation, purification techniques, and powerful identification methods are recommended to improve their antioxidant activity.
