An Abattoir Survey Of Liver And Lung Helminthic Infections In Local And Imported Sheep In Jordan, Anwar Maraqa, Zuhair Sami Amr, Lina Rifai, Walid Al-Melhim Jan 2005

An Abattoir Survey Of Liver And Lung Helminthic Infections In Local And Imported Sheep In Jordan, Anwar Maraqa, Zuhair Sami Amr, Lina Rifai, Walid Al-Melhim

Turkish Journal of Veterinary & Animal Sciences

The livers and lungs of 5596 sheep (443 local, 473 Romanian and 4680 Australian) slaughtered in Amman Central Abattoir during November-December 1999 were examined in routine meat inspection procedures for helminths. Dictyocaulus filaria, hydatid cyst, Fasciola hepatica and Dicrocoelium dendriticum were recovered from the examined sheep with variable prevalences. Dicrocoelium dendriticum is reported from the livers of imported sheep in Jordan for the first time.


An Abattoir Survey Of Gastro-Intestinal Nematodes In Sheep In The Burdur Region, Turkey, Şi̇nasi̇ Umur, Bayram Ali̇ Yukari Jan 2005

An Abattoir Survey Of Gastro-Intestinal Nematodes In Sheep In The Burdur Region, Turkey, Şi̇nasi̇ Umur, Bayram Ali̇ Yukari

Turkish Journal of Veterinary & Animal Sciences

The gastro-intestinal (GI) organs of 50 sheep randomly selected from local abattoirs in the Burdur region were investigated between September 2000 and August 2001 for the prevalence of GI nematodes and their larval forms and the seasonal fluctuations of these parasites. All the animals examined were infected (100%) with GI nematodes. Twenty-two nematode species were identified and 38,639 nematodes were collected from the infected sheep. The number of parasites per sheep ranged from 11 to 5052 (mean 772.78), while the number of nematode species per animal ranged from 1 to 12 (mean 5.98). The most frequently detected nematodes in the …

Feeding Behaviour Of Awassi Sheep And Shami (Damascus) Goats, Mahmut Keski̇n, Ahmet Şahi̇n, Osman Bi̇çer, Sabri̇ Gül, Şerafetti̇n Kaya, Ayhan Sari, Meti̇n Duru

Turkish Journal of Veterinary & Animal Sciences

Seven male Awassi sheep and 7 male Shami (Damascus) goats, one year old and fed with a diet having 2503 Kcal ME and 155 g crude protein kg^{-1}, were housed individually for 49 days to determine the feeding behaviour. Each animal within each species was one replicate and kept individually within 100 x 120 x 120 cm wood pen in indoor conditions with natural daylight and 11-18 °C room temperature. Twice a week, starting right after daily feed refreshment at 12.00, behavioural observations were made at 12.00, 16.00, 20.00, 24.00, 04.00 and 08.00 with 5-minute intervals by monitoring the animals. …


Determination Of Seropositivity For Toxoplasma Gondii In Sheep In Şanlıurfa Province, Murat Sevgi̇li̇, Cahi̇t Babür, Serpi̇l Nalbantoğlu, Gülçi̇n Karaş, Zati̇ Vatansever Jan 2005

Determination Of Seropositivity For Toxoplasma Gondii In Sheep In Şanlıurfa Province, Murat Sevgi̇li̇, Cahi̇t Babür, Serpi̇l Nalbantoğlu, Gülçi̇n Karaş, Zati̇ Vatansever

Turkish Journal of Veterinary & Animal Sciences

The aim of this study was to detect the seropositivity for Toxoplasma gondii in sheep in Şanlıurfa province using the Sabin-Feldman dye test. Serum samples collected from 300 sheep were tested for T. gondii. Serological examination revealed 167 (55.66%) sheep to be seropositive. Among these sera the numbers of seropositive samples at certain dilution steps were as follows: 65 at 1/16, 63 at 1/64, 27 at 1/256 and 12 at 1/1024. There was no significant correlation between seropositivity and the factors age, sex and breed. In conclusion, detection of a 34% seropositivity rate in 1/64 and higher dilutions indicates the …


Prediction Of Dry Matter Intake And Dry Matter Digestibilities Of Some Forages Using The Gas Production Technique In Sheep, Adem Kamalak, Önder Canbolat, Yavuz Gürbüz, Osman Ozay Jan 2005

Prediction Of Dry Matter Intake And Dry Matter Digestibilities Of Some Forages Using The Gas Production Technique In Sheep, Adem Kamalak, Önder Canbolat, Yavuz Gürbüz, Osman Ozay

Turkish Journal of Veterinary & Animal Sciences

Wheat straw, barley straw, alfalfa hay, alfalfa silage and maize silage were offered ad libitum to three male sheep, and daily dry matter intake (DMI) and apparent dry matter digestibility (DMD) were measured. Samples of forages were incubated with rumen fluid to determine gas production. Gas productions were measured at 3, 6, 12, 24, 48, 72 and 96, and gas production constants (a, b, c,) were described using the equation y = a + b (1 - e-^{ct}). Gas production at all incubation times and gas production constants (c, b and a+b) were significantly (P < 0.001) correlated to DMD or DMI. Although the gas production constant c explained 74% of the variation of DMD, the gas production constant b explained 92% of the variation of DMD. The gas production constants c and (a+b) in combination explained 96% of the variation of DMD. The gas production constants b and c alone explained 70% and 78% of the variation of DMI respectively. The gas production constants in combination explained 84-90% of the variation of DMI. It was concluded that the accuracy of predicting DMD or DMI can be increased when gas production constants are used in combination, and the in vitro gas production technique has good potentiality to predict DMD and DMI.

Turkish Journal of Veterinary & Animal Sciences

The purpose of this study was to investigate the effects of early age mating on reproductive traits and survival rate and lamb growth of Bafra sheep. The animals used in the study were divided into two groups (Group I and Group II) according to age of animals. The animals in Group I, 344 ewe lambs, were about 10 months of age, while the animals in Group II, 174 yearlings, were about 18 months of age. The same feeding and management conditions were practised for both groups during mating season and pregnancy and lactation periods. The pre-mating live weights were 43.53 …

Turkish Journal of Veterinary & Animal Sciences

Glutathione reductase (Glutathione: NADP^+ oxidoreductase, EC 1.8.1.7; GR) was purified from sheep liver. The purification included 4 steps: preparation of homogenate, ammonium sulfate fractionation, 2', 5'-ADP Sepharose-4B affinity chromatography, and gel filtration chromatography. GR was obtained with a yield of 14.1% having a specific activity of 47.27 EU/mg proteins. Optimal pH, stable pH, and optimal temperature were 8.0, 5.5, and 60 °C, respectively. K_M and V_max values for NADPH and GSSG substrates were 0.0258 and 0.0239 mM, and 0.266 and 0.255 EU/ml, respectively. The overall purification was about 1477-fold for liver GR. The enzyme activity was measured spectrophotometrically at 340 …
