Abstract
Industrial poultry is one of the fastest growing and an important source of protein(egg and
meat)to man.Coccidiosis, caused by protozoa parasites of the genus Eimeria, recognized as
most common and economic problem worldwide.Study was conducted to determine the
prevalence of coccidian(Eimeria spp.)in broiler and grand-parent and parent chicken farms in
Ghout sultan poultry and dairy project.Data collcted were obtained by linkage to veterinary
laboratory and statistics office for the period1987-2003.Data collected were analysis using
SPSS and Chi- square test. P–values less than 0.05(p<0.05)was considered significant.The
study revealed that the prevalence rate of coccidiosis (Eimeria spp.) were recorded
68.6%(288/420)in the broiler chicken farms as compare with grand-parent and parent farms
34.5%(145/420).A marked monthly, the highest prevalence of coccdiosis was during
December (81.1%)for the broiler farms, while the lowest rate in June(48.1%).On the other
hand,the highest rate of coccdiosis was recorded in January and July(48.4%),and lowest rate
in the February(13.9%)for the grand-parent and parent chicken farms Seasonally, the highest
prevalent of coccidiosis was showed during winter season(30.21%),and the lowest rate was
recorded in the summer(18.40%)for broiler chicken farms .In the grand-parent and parent
chicken farms, The highest prevalence was noticed during summer season (27.59%),while the
lowest rate was recorded during winter season (22.76%).The highest infection rate were
observed in farm 6(8.3%),and the lowest rate in farm4(4.8%) for broiler chickenfarm.Where
the grand-parent and parent chicken farms, the highest rate was recorded in
farm15(4.8%),where the lowest rate in farm20(1.4%).The results indicated,the higher
infection of disease(15.5%)in 2002and 2003compared to other years,and the lowest rate in
1987(2.9%).The current study gave the proof of the endemicity of coccidiosis in this rearing
system, and the deep litter system of management remains an important factor in the
occurrence of the disease.For instance,suitable strategies need to be designed in order to
reduce the impact of coccidiosis.In addition, further studies are needed to be conducted to
identification of coccidian species for the determine of suitable prevalent and control method

Fluctuating asymmetry, commonly used as an indicator of environmental pollution, was estimated in eye lens diameter, pectoral fin, pelivical fin and gill arch length of Siganus rivulatus collected from Jalyanah beach. Mean length, weight and condition factor of 15.76 ± 1.72 cm, 50.33 ± 13.05 g and 1.05 ± 0.18 were correspondingly record. The eye lens diameter (t =-0.01), pectoral fin (t =-0.05), pelivical fin (t =-0.06) and gill arch length (t =-0.05) from both sides were not significantly different. The pectoral fins recorded (0.005 ± 0.022) higher occurrence of fluctuating asymmetry compared with the eye lens diameter (0.002 ± 0.1173, pelivical fins (0.004 ± 0.01578) and gill arch length (0.001 ± 0.02445). Changeable degrees of fluctuating asymmetry were practical in response to ecological stress and could be a useful use as a marker to environmental stress in marine ecosystems.

The Diabetes it is a major contributor to the development of many pathological processes including hypertension, hyperlipidemia, and cardiovascular diseases. both animal and human studies indicates that gut microbial change is associated with diabetes, but such an association with T2DM in Libyan people is not known. Therefore, the aim of present study is to recognize if there is a difference in the bacterial composition between Libyan diabetic patients and a healthy control. Also, to find whether there is a relationship between bacterial composition and diverse factors such as FBS, HbA1c, and lipid profile and body composition. Two groups of participated in this study including 20 patients with type 2 diabetes and 28 healthy control subjects were involved. The fecal microbiota structure at level of species was investigated by using conventional culture method. There was significant difference in gut bacteria between diabetic patients and healthy control. The relative abundance of B. vulgatus, and B. rodentium were significantly declined in the diabetic group compared to non-diabetic group (P = 0.008, P = 0.018) but B. vulgatus negatively and significantly correlated to level of HDL-C (P = 0.015). Moreover, the relative abundance of L. acidophilus reduced significantly (P = 0.02) and correlated positively and significantly with Fasting blood sugar (P = 0.001) and HbA1c (P = 0.016) in diabetic patients compared to the healthy control group. Our results show that T2DM is associated with compositional alterations in gut microbiota. B. vulgatus, B. rodentium and L. acidophilus B. may be possible indicators of T2DM. The interaction of specific gut microbiota with FBG, HbA1c, and HDL-C should be considered as potential interest for future studies to develop better approaches for the prevention and treatment of T2DM by modulation of gut microbiota.

It is known that, there are two types of human ear lobes. free earlobes (unattached) which is dominant trait (E-) and attached earlobes that is recessive trait.There is limited studies on the frequency of these types among libyain population. The main goal of this study was to determine the human inheritance trait for earlobes and to see whether there is an effect for gender in this inheritance trait study. A samples of 1389 (679 male and710 female) from students were involved. Results showed that the frequency of unattached type earlobe was 69.4%. and attached was 30.6 %. Both sexes in the population have higher frequency of unattached (65.5% in male and 73.1% in females) there was Statistically nonsignificant in female. (P value lower than0.05, Chi-Square value of 23.2) was calculated where the null hypothesis was rejected. The states that normal distribution for Mendel are data on the basis of 3:1 ratio and this could be related to male Chi-square effect. In conclusion, the unattached earlobes is the most commonly type which is the dominant, in Libyan population. .This suggesting more studies are necessary including large sample size and observing further associated attribute to ear lobes such as blood groups that were needed.

Breeding values (BV) for some productive and reproductive traits of Holstein Friesian under Libyan conditions were estimated and compared with those estimated under, European, and North American conditions in an attempt to assess the genotype environment interaction. To investigate the effect of managerial conditions on the same traits, the heritability coefficients were also estimated under Libyan and Dutch managements. The trait's variance and covariance components and the breeding values of sires were computed using the REML method based on mixed model containing the fixed effects of month of calving, year of calving, management and generation and the random effect of sires. The lactation period and age at calving were used as covariates. Genetic correlation values of EBV for the milk yield traits were less than 1. Differences in heritability estimates due to the management system and or to environmental factors reflect Genotype x Environment interaction. Milk yield traits except dry period had a higher EBV during the Libyan than Dutch management. Reproductive traits except Age at first calving also had a higher EBV during Dutch than Libyan management. Correlations between EBV for milk yield ranged between 0.16 and 0.56 during Libyan, European and North American conditions. EBV of both North American and European sires were medium, low and negatively ranked under Libyan environment. EBV of milk yield traits showed higher variability under the Libyan environment. Sires with low EBV (> 500) revealed negative ranking under the Libyan conditions.
