This study was conducted to evaluate the effects of providing shade on growth performance, welfare, and meat quality of grazing sheep under high ambient temperature. A total of 120 healthy male Ujumqin wool sheep (a local breed; BW = 18.7 ± 1.27 kg; 14 wk old) were randomly and equally divided into shaded and unshaded treatments with 3 pens per treatment. Sheep were grazed on an unshaded pastur...

Parasitic infections adopt a rather low profile in the highly urbanized setting in Singapore. Very few food-borne parasitic infections are encountered. Apart from a few reports of infections with Clonorchis/Opisthorchis, Taenia spp. and hydatid disease, there are no other citations of such helminthic infections. Seroprevalence surveys have shown the presence of toxoplasmosis in local meat anima...

BACKGROUND The abomasal helminth Teladorsagia circumcincta is one of the most economically important parasites affecting sheep in temperate regions. Infection is particularly detrimental to lambs, in which it can cause pronounced morbidity and severe production losses. Due to the spreading resistance of this parasite to all classes of anthelmintic drugs, teladorsagiosis is having an increasingl...

Anthelmintic efficacy of levamisole, albendazole, ivermectin and morantel tartrate was evaluated in 75 sheep naturally parasitized with Haemonchus, Trichostrongylus, Oesophagostomum and Ostertagia spp. Results revealed that levamisole, albendazole, ivermectin and morantel tartrate were lOO, 98.82, 97.02 and 76.50 per cent effective, respectively in reducing the eggs per gram of faeces. The anim...

Six castrated male Karagouniko sheep, offered three levels of water, were used in a 3x3 Latin Square design to study the effects of mild water restriction on roughage intake and digestion. The three treatments were offered water ad libitum throughout the day (A), made available to the animals for 1h daily (B) or 65% of the water consumed ad libitum (C). Sheep in Treatment A consumed more water ...

Tropical Africa contains almost one tenth of the world's sheep and over a quarter of its goats. Small ruminant production throughout this area takes place entirely under traditional systems, and since the meat produced is mostly for home consumption, a great deal of it escapes official marketing channels. As a result there is an undeniable lack of knowledge as to the part played by sheep and go...

A molecular PCR study using DNA from 21 hydatid cysts was performed to determine which strain type is responsible for human infection in Peru. The mitochondrial cytochrome c oxidase subunit 1 (CO1) gene was amplified in 20 out of 21 samples, revealing that all but 1 sample (19/20, 95%) belonged to the common sheep strain (G1). The remaining samples belonged to the camel strain (G6). The G1 geno...

During the oestrous cycle of the sheep, normal regression of the corpus luteum (cl) on Day 15 is prevented by total hysterectomy and the cycle is extended to a length approximating the gestation period (Wiltbank & Casida, 1956; Moor & Rowson, 1964). Rowson & Moor (1964) also reported that the increased life-span of the cl in partially hysterectomized sheep was roughly proportional to the amount...

The ovary not containing the corpus luteum was removed from each of fifty-two ewes on Day 8 of the cycle. These animals were then allocated to one of the following groups. Group 1 : (control) received no further treatment. Group 2: the contralateral uterine horn, i.e. located on the side opposite to the corpus luteum, was removed. Group 3 : the ipsilateral uterine horn, i.e. located on the same...

Human-carnivore conflicts over livestock depredation are increasingly common, yet little is understood about the role of husbandry in conflict mitigation. As shepherds and guarding dogs are most commonly used to curb carnivore attacks on grazing livestock, evaluation and improvement of these practices becomes an important task. We addressed this issue by studying individual leopard (Panthera pa...
