Item Metadata only Effect of intravaginal fluorogestone acetate sponges on prolactin levels of Damascus-local cross breed goats(Springer Netherlands, 2015) Talafha, A.; Ababneh, M.; Khalifeh, M.; Al-Majali, A.The effect of intravaginal fluorogestone acetate (FGA) sponges on prolactin levels (PRL) and correlations between PRL and milk somatic cell count (SCC) and steroid hormones levels of Damascus-local cross goats during transitional period to anestrous were investigated in this study. Fifty-six goats were assigned to three groups. Group 1 (FGA, n =19) was treated with 40 mg FGA and equine chorionic gonadotropin (600 IU, i.m.) at time of sponge withdrawal (day 0). Group 2 (FGA-PGF; n =19) was treated similar to group 1 but was also injected with dinoprost tromethamine (naturally occurring PGF 2 α )(10mg,i.m.)on day 0.Control goats ( n =18) were left untreated. On day 0,five fertile bucks were turned in with all goats. Milk and blood samples were collected on days − 13 (day of sponge insertion), − 6, 0, 1,2, 7, 13, and 20. Prolactin levels were at lowest values on day − 13 of the study and increased ( p <0.05) from day − 6 to day 20 in all groups. A significant positive correlation ( p <0.05) between PRL and progesterone and between PRL and estradiol levels was found in this study. No significant correlation was found between PRL and SCC of all groups during the study except on days 2 and 20 where PRL levels were correlated ( p <0.05) with SCC of left udder halves of FGA group. In conclusion, estrus induction with FGA result- ed in significant increase in PRL. A positive correlation was found between PRL and steroid hormones, but there was no correlation between PRL and goat milk SCC.Item Metadata only Epidemiologic study on Besnoitia besnoiti infection in dairy herds in Jordan(Springer, 2015) Talafha, A.; Al-Majali, A.; Ababneh, M.; Abutarbush, S.Besnoitia besnoiti is an apicomplexan parasite and the causative agent of bovine besnoitiosis which is considered as a re-emergent disease in Europe. A cross-sectional serological study was conducted to determine the seroprevalence and to identify risk factors associated with B. besnoiti infection in 68 dairy herds (n = 806 cows) in Jordan during the period from January to June 2007 and the spring of 2014. Data regarding herd's management was obtained by filling questionnaires through personal interviews with farmers. An indirect ELISA test was used to detect antibodies against B. besnoiti. Chi-square analysis and multivariable logistic regression model were used to identify risk factors associated with seropositivity to B. besnoiti. At the individual cow and herd level, the true prevalence of seropositive animals was 6 and 28.7 %, respectively. Cows between 2 and 6 years of age had significantly higher seroprevalence of B. besnoiti than other age groups. The highest seroprevalence of B. besnoiti was found in Zarqa and Irbid governorates. Multivariable logistic regression model identified that exchanging visits by farm workers to neighboring farms as a risk factor for seropositivity to B. besnoiti, while smaller herd size and twice a day farm cleaning using sweeping and water hosing were identified as protective factors. This is the first study that investigated the seroprevalence of B. besnoiti infection in dairy herds in Jordan. Further studies are warranted to explore the clinical manifestation of B. besnoiti infection as well as to identify the possible presence of other Besnoitia species and definitive hosts for the parasite.Item Metadata only Prevalence and risk factors associated with bovine viral diarrhea virus infection in dairy herds in Jordan(Kluwer Academic Publ, 2009) Talafha, A.; Hirche, S.; Ababneh, M.; Al-Majali, A.; Ababneh, M.A cross-sectional study was carried out to determine the seroprevalence and to identify risk factors associated with bovine viral diarrhea virus (BVDV) infection in 62 non-vaccinated dairy herds (671 cows) in Jordan between January and June 2007. Information regarding herd management was recorded through a personal interview with farmers. Antibodies against BVDV were detected using an indirect ELISA test. Chi-square analysis and multivariable logistic regression model were used to identify risk factors for BVDV seropositivity. The true prevalence of antibodies against BVDV in individual cows and cattle herds was 31.6% and 80.7%, respectively. The seroprevalence of BVDV in medium and large size herds was significantly higher than that in smaller herds. There was no significant difference in BVD seroprevalence between different age groups. Random-effects logistic regression model revealed two major factors associated with seropositivity to BVDV; exchange of visits between adjacent farm workers and not isolating newly purchased animals before addition to the herd. The seroprevalence of BVDV in cows located in the northern Jordanian governorates was significantly higher than that in other studied governorates. Results of this study indicated that BVDV is highly prevalent in Jordan and BVDV infection could be controlled by livestock-trade control, and applying strict biosecurity measures in the dairy farms.Item Metadata only Seroprevalence and risk factors for bovine brucellosis in Jordan(Korean Society of Veterinary Science, 2009) Al-Majali, A.; Talafha, A.; Ababneh, M.We investigated the seroprevalence and risk factors for Brucella seropositivity in cattle in Jordan. The sera from 671 cows were randomly collected from 62 herds. The antibodies against Brucella were detected using a Rose Bengal plate test and indirect ELISA. A structured questionnaire was used to collect information on the cattle herds' health and management. A multiple logistic regression model was constructed to identify the risk factors for Brucella seropositivity. The true prevalence of antibodies against Brucella in individual cows and cattle herds was 6.5% and 23%, respectively. The seroprevalence of brucellosis in cows older than 4 years of age was significantly higher than that in the younger cows. The seroprevalence of brucellosis in cows located in the Mafraq, Zarqa and Ma'an governorates was significantly higher than that of the other studied governorates. The multiple logistic regression model revealed that a larger herd size (odd ratio OR = 1.3; 95% CI: 1.1, 2.6) and mixed farming (OR = 2.0; 95% CI: 1.7, 3.7) were risk factors for cattle seropositivity to Brucella antigens. On the other hand, the use of disinfectants (OR = 1.9; 95% CI: 1.1, 2.1) and the presence of adequate veterinary services (OR = 1.6; 95% CI: 1.2, 3.2) were identified as protective factors.Item Metadata only The effect of estrus synchronization treatments on somatic cell count of transitional-anestrus Awassi ewes' milk(Kluwer Academic Publ, 2009) Talafha, A.; Lafi, S.; Ababneh, M.Fifty-three transitional-anestrus Awassi ewes, randomly assigned to three groups: fluorogestone acetate (FGA, n = 18), FGA-Prostaglandin (FGA-PGF, n = 18) and control (n = 17), were used to examine the effect of estrus synchronization protocols and steroid hormones concentrations on milk somatic cell count (SCC). Intravaginal FGA sponge was inserted for 13 days and 600 IU equine chorionic gonadotropin was administered for ewes of FGA and FGA-PGF groups at the time of sponge removal (day 0). In addition, 10 mg was administered to ewes of FGA-PGF group on day 0. Blood and milk samples were collected from all ewes on days -13, -6, 0, 1, 2, 7 and 14. Estradiol had significant positive correlation with the SCC during the periods of sponge insertion (P = 0.015, r = 0.235) and within two days (P = 0.063 r = 0.23) after sponge removal with no correlation with SCC of both udder halves during the luteal phase. Progesterone concentrations, on the other hand, had a significant positive correlation (P < 0.001; r = 0.420) with the SCC of both udder halves during the luteal phase of the experiment, but not during the periods of sponge insertion and expected estrus. SCC returned under the influence of endogenous progesterone on days 7 and 14 to pre-synchronization values. In conclusion, sheep milk SCC is affected significantly with induction of estrus and steroid hormones concentrations. However, peak SCC recorded during estrus was far below the upper limit of the current standard for normal milk. With the current standards for SCC of 1,000,000/ml as legal limit for abnormal milk control programs in sheep, estrus synchronization programs and the estrus status should not be considered when bulk-tank milk SCC is being investigated, but should be considered during the process of setting new standards.Item Metadata only The effect of estus synchronization treatment on somatic cell count of transitional-anestrus local-Damascus cross breed goats' milk(Kluwer Academic Publ, 2008) Talafha, A.; Lafi, S.; Ababneh, M.An experiment was conducted to examine the effect of estrus synchronization protocols and steroid hormones concentrations on somatic cell count (SCC) of transitional-anestrus local-Damascus cross goats’ milk. Fifty-six goats (2–4-year old) were randomly assigned to three groups: fluorogestone acetate (FGA, n = 19), FGA-Prostaglandin (FGA-PGF, n = 19) and control (n = 18) groups. Intravaginal sponge containing 40 mg FGA was inserted for 13 days and an injection of 600 IU equine chorionic gonadotropin (eCG) was administered for goats of FGA and FGA-PGF groups at the time of sponge removal (day 0). In addition, goats of FGA-PGF group were injected with 10 mg dinoprost tromethamine (PGF₂α) on day 0. Five fertile local-Damascus cross bucks were turned-in with all goats on day 0. Blood and milk samples were collected from all goats on days -13 (beginning of experiment), -6, 0, 1, 2, 7, 13 and 20 (end of the experiment). Four-year old and second-parity goats had significantly higher (p < 0.05) SCC of both udder halves than 2- and 3-year old and first-parity goats, respectively. There was a significant effect (p < 0.05) for treatment and number of kids born in the last kidding season on SCC of both udder halves. Neither estradiol nor progesterone concentrations were correlated with SCC in goats in this experiment. The SCC of both udder halves and left udder halves in goats of the control and FGA groups, respectively, increased significantly (p < 0.05) after sponge removal and buck introduction when compared with day 0, with no differences in the FGA-PGF group. This increase in SCC of the control and FGA groups coincided with peak estrus behavior. However, SCC was far below the upper limit of the current standard for normal milk. In conclusion, induction of estrus with progestagen based programs and buck introduction may cause temporary significant increase in SCC. However, the SCC values during this period of temporary increase were still in the range of acceptable values for normal milk. With the current standards for SCC of 1,000,000/ml as legal limit for abnormal milk control programs in goats, estrus synchronization programs and the estrus status should not be considered when bulk-tank milk SCC is being investigated.
