    Blocade of the ?-adrenoceptors with carazolol improves fertility of artificial insemination in Awassi sheep
    (2007) Bademkiran S.; Celik R.; Gurbulak K.; Yokus B.; Ozdemir N.
    This investigation aimed to study the effect on fertility parameters of one or two artificial inseminations (AI) and the administration (carazalol) before insemination of ?-adrenoceptor blocker in Awassi sheep. A total of 144 Awassi sheep with their oestrous synchronized were divided into 4 groups. Group A1 had a single artificial insemination applied at 52 hours after (the sponge was removed), group A2 had a single artifical insemination applied while for preinsemination 0.01 mg/kg carazalol were given i.v. Group B1 had artificial insemination appled twice at 52 and 60 hours. B2 group had artificial insemination appled twice at 52 and 60 hours and for preinsemination 0.01 mg/kg carazalol were given i.v. As a results, the ratios of not observed oestrus after 25 days were 55.6%, 61.1%, 63.9% and 69.4% in groups A1, A2, B1 and B 2 respectively. The ratios of pregnancy were diagnosed ultrasonographically after the 30th day of artificial insemination as 47.2%, 50.0%, 52.8% and 61.1% in groups A1, A2, B 1, and B2 respectively. The ratios of birth by means of artificial insemination were 41.7%, 47.2%, 47.2% and 55% in groups A 1, A2, B1 and B2 respectively. The degree of fertility was found to be higher in the group in which the sheep applied artificial insemination twice with 8 hours intervals and administrated ?-adrenoceptor blocker preinsemination. However, the difference between groups was not significant (p>0.05).

    Comparison of Pelargonium sidoides, placebo and antibiotic treatment of chronic endometritis in dairy cows: A field trial
    (2009) Bademkiran S.; Kurt D.; Yokus B.; Celik R.
    We compared the effects of the intrauterine application of an extract of Pelargonium sidoides (EPs 7630) to parenteral antibiotic injection in the treatment of chronic endometritis, which is commonly encountered postpartum in cows. Forty six cows diagnosed with chronic endometritis 21-27 days postpartum were selected and divided into 3 groups. Cows in Group I (n = 16) received a physiological parenteral injection of 10 mL of serum per day for 3 days. Similarly, cows in Group II (n = 15) received 1 mg kg-1 ceftiofur (Ceftivil®) parenterally. Those in Group III (n = 15) received an 8 mg (10 mL)/cow intrauterine dose of EPs 7630 (Umca®) for 3 days. When examined between the 35th and 41st day, clinical recovery rates were found to be as follows: for Group 1,1/16 (6.2%); for Group II, 8/15 (53.3%) and for Group II, 4/15 (26.69%). After this examination, cows whose chronic entrometritis symptoms persisted according to clinical and rectal examination received a further 3 days of the treatment appropriate to their group. Later on various parameters were identified thus, for Groups I-III, respectively: insemination rate 87.5, 66.6 and 93.3%; days to 1st service 103.5, 91.0 and 96.0; 1st service conception rate 28.5, 40.0 and 35.7%; days open 140,120 and l31 and cows pregnant within 250 DIM 56.25, 80.0 and 66.6%. © Medwell Journals, 2009.
