Carpal conformation is thought to contribute to the frequency of carpal pathology so non-invasive measurement of carpal morphometry would be useful to identify joints at risk. However, there are scant radiographic morphometrical details for the carpals of Thoroughbred (TB) and Standardbred (SB) racehorses even though these breeds differ in the incidence of carpal damage. This study aimed to identify morphometrical similarities and differences in carpal conformation in TB and SB. Thirty carpal dorsopalmar radiographs (DP) were collected from 15 TB and 15 SB. All DP radiographs were at zero degrees or within the acceptable range of rotation. Twelve carpal radiographic parameters were selected and measured on each radiograph. Statistical analysis found significant differences in four carpal parameters. These parameters revealed that the middle carpal joint in SB was significantly more angled distomedially whereas the radial distal metaphysis showed a greater distolateral inclination in TB. The radiocarpal and the carpometacarpal articulations exhibited common features in the two groups of horses. These carpal traits in TB and SB highlight their potential association with loading distribution and pathology. Measuring carpi from untrained and injured horses is necessary to establish breed specific features for the ideal carpal conformation in each of these breeds.

This study was conducted to investigate the prevalence of Newcastle Disease, Avian Influenza, Infectious Bronchitis, and Infectious laryngotracheitis in some regions of Tripoli-Libya. Serum samples were collected from Four broiler farms in Wadi Alrabea area, two layer farms and one backyard farm in Gaser Bin Gasher, two layer farms in Alswani and one backyard farm in Zliten City and screened for the presence of antibodies against LPAI-H9, HPIA-H5, HPIA-H7, ND, IB 4/91 strain using the HI test and antibodies against ILT virus by ELISA. The overall seroprevalence of H9, H5, H7, ND, IB4/91 and ILT was 26.5%,0%,0%,, 29.5%,43% and 30% respectively. All sera tested for AI-H5 and AI-H7 were negative. In Wadi Alrabea flocks, seroprevalence of H9, H5, H7, ND, IB4/91 and ILT was 44%, 0%, 0%, 16.28%, 32.56% and 0% respectively. Where as in Gaser Bin Ghasher, was 24%,0%, 0%, 33.87, 36.29% and 39% respectively. In Alswani, the seroprevalence was 8.70%, 0%, 0%, 52.17%, 54.35% and 54.3%. The seroprevalence of H9, H5, H7 in Gaser Bin Ghasher backyard chickens was 23%, 0%, 0% respectively and the seroprevalence of H9, H5, H7, ND, IB4/91 of Zliten backyards was 12%, 0%, 0%, 12%, 96% respectively. Further investigations are recommended to identify the circulating virus genotypes and models of transmission for better understanding of these viruses epidemiology in backyard chickens in Libya. Vaccination of backyard chickens against ND using heat resistant strain is highly recommended.

Abstract: The objective of this study was to determine the Serum levels of sodium, potassium, calcium, magnesium, chloride and phosphorus were determined in one-humped camels (Camelus Dromedarius) of different age, sex and maternal status of female camels. Eighty-seven of apparently healthy one-humped camels aged from less than two years old to fifteen years old were used in this study. Animals were categorized into three age groups [< 2years (23), 2-5 years (14) and > 5 years (50)], two sex groups [males (37) and females (50)] and three maternal status groups [non-pregnant (13), pregnant (12), lactating (12)]. The total levels of sodium, potassium, calcium, magnesium, chloride and phosphate were 148.1, 6.4, 112.3, 9.4, 2.2 and 7.2, respectively. The age of camel was found to be significantly effect the level of calcium, magnesium and phosphorus. While, the sex of camel had a significant effect on phosphorus. Meanwhile, the maternal status of female did not affect the blood electrolytes. It conclude that, the calcium, magnesium and phosphorus concentration change with advance age. While, sex of animal had only a significant effect on phosphorus.
