Efficacy of marbofloxacin against respiratory infections of lambs
(2007)
The trial was carried out in a sheep flock with mixed Mannheimia haemolytica/Mycoplasma spp. respiratory infection; 60 lambs were included therein and allocated as follows: lambs in group MH were subcutaneously injected ...
Use of lincomycin to control respiratory infections in lambs: Effects on health and production
(2006)
The efficacy of lincomycin to control respiratory infections in lambs was assessed in two trials. In trial 1, 72 lambs with active mycoplasmal pneumonia were allocated as follows: lambs in group T2 were treated with ...
The effect of repeated follicular aspiration on the onset of puberty and growth rate of winter- or autumn-born lambs
(2009)
The effects of follicular aspiration for oocyte retrieval on the attainment of puberty and growth rate were studied in winter-born (9 treated and 6 control) and autumn-born (5 treated and 5 control) ewe lambs. In the treated ...
Progesterone concentration as an indicator of ovarian response to superovulation in Chios ewes
(2002)
We investigated the prediction of the ovarian response to superovulation using progesterone (P-4) determination in Chios ewes. During the estrus period, estrus synchronization and multiple ovulations were induced in 100 ...
Supplementation of lactating ewes with a glucogenic preparation or beta-carotene in mid- to late lactation on subsequent milk yield and luteinizing hormone secretion
(2007)
The effects of a glucogenic preparation (Nutrimix((R))) or beta-carotene (Rovimix((R)) beta carotene) supplementation of ewes during mid- to late-lactation on their milk yield were assessed in a study where 66 Chios-breed ...
Comparison of fluorescence polarization assay, indirect ELISA and competitive ELISA methods for diagnosis of Brucella melitensis-infection in small ruminants
(2004)
Three serological tests, the fluorescence-polarization assay (FPA), the indirect ELISA (iELISA) and the competitive ELISA (cELISA), were compared in detecting Brucella melitensis antibodies in 454 serum samples from sheep ...
Effects of lamb sucking on the bacterial flora of teat duct and mammary gland of ewes
(2008)
We aimed (i) to determine differences in bacterial flora of teat duct and mammary gland of ewes before and after suckling, (ii) to evaluate factors potentially affecting those. We collected samples of teat duct material ...
The effects of inoculation of Mannheimia haemolytica into the teat of lactating ewes
(2005)
The objectives of the work described in this paper were: (i) to study the outcome of challenging ewes with Mannheimia haemolytica, at different sites of their teats, (ii) to compare the effects of two different isolates ...
Teat disorders predispose ewes to clinical mastitis after challenge with Mannheimia haemolytica
(2006)
In order to study the effects of sheep teat disorders on the protection of the mammary gland, we used a Mannheimia haemolytica isolate, which did not cause clinical mastitis when deposited into intact teats. In the first ...
