“…The greater bioavailability of organic forms of Se such as selenised yeast, has been reported by several research studies (Rock et al, 2001), although some investigators have demonstrated superior absorption and retention of inorganic forms (Van Metre and Callan, 2001). Productive responses to Se supplementation using inorganic forms of Se have also been reported.…”

“…Selenium deficiencies have been reported in soils, herbages and consequently in livestock blood concentrations in USA (Van Metre and Callan, 2001), Australia (Tinggi, 2003), New Zealand (Watkinson, 1983) and also within the UK (Blaxter, 1963;Anderson et al, 1979;Wang et al, 1987) and Ireland (Mee et al, 1994). In Northern Ireland in particular, McMurray and Rice (1982) have reported the Se status of livestock to be highly deficient with 85% of beef herds being below the threshold of what is considered adequate.…”

The objective of this study was to determine the effects of selenium (Se) supplementation of mature ewes in the period from day 214 to day 90 post mating on Se status, productivity and viability of ewes and their offspring. Multiparous crossbred ewes (n 5 82) were randomly assigned to receive a standard dried grass-based diet (control) or dried grass diet supplemented with 1 g of selenised yeast (Selplex R ), providing 0.5 mg Se per ewe per day. After day 90 post mating, all ewes were offered grassbased diets supplemented with a standard multivitamin and mineral mix, up to lambing. Ewes that were fed additional Se had increased (P , 0.001) activity of glutathione peroxidase enzyme (GPx) and increased plasma Se concentrations throughout the treatment period. At lambing, GPx activity of supplemented ewes was higher (P , 0.001) than that of controls. Twenty-four hours after birth, lambs of ewes given Se had higher (P , 0.001) concentration of Se in plasma, greater (P , 0.001) activity of GPx and better (P , 0.01) immune status. Lambs of ewes that received supplementation showed a faster progression to stand than control lambs (P , 0.05), independent of maternal behaviour which was not affected. Supplementation reduced perinatal lamb mortality (0.04 v. 0.17; P , 0.05). However, overall mortality from birth to weaning was unaffected (P . 0.05). Supplemented ewes weaned lambs on average 2 kg heavier than control ewes, due to the higher (P , 0.05) growth rates achieved by their offspring. In conclusion, for ewes with a marginal Se status, an organic source of Se supplemented throughout pregnancy, compared with supplementation only in the last trimester, positively affected measures of lamb viability and survival.

“…inform.). Related to the knowledge of hepatic selenium in domestic ruminants, the measured selenium concentration in this roe deer must be regarded as deficient (Van Metre and Callan, 2001). The implication of low selenium status is unknown, but selenium deficiency may cause myodegeneration and impaired immunity.…”

ABSTRACT:This paper describes a case of Anaplasma phagocytophilum infection in a roe deer (Capreolus capreolus) calf in Norway. The calf was found deserted, paretic, and heavily infested with Ixodes ricinus ticks. It was euthanized and investigated postmortem. Anaplasma phagocytophilum was detected in several tissues by polymerase chain reaction (PCR) and 16S rRNA sequence analyses. Analyses for Borrelia burgdorferi sensu lato and tick-borne encephalitis (TBE) virus infections were negative. This is the first report of a possible paretic condition in A. phagocytophilum infected roe deer.

“…Under the microscope severe changes in the muscle will be seen. In other cases, the muscle takes on a pale appearance of "fish-flesh" (13). Treatment is accomplished by the use of vitamin E and selenium because the condition can be caused by a deficiency of selenium, vitamin E or both.…”

Vitamins are essential for the health of all living organisms. Vitamins E, A, D and K are known as fat-soluble vitamins, and deprivation of vitamin E causes various disorders, especially in the reproduction and cardiovascular systems and in muscle functions. Vitamin A, on the other hand, has roles in various biological functions – like eyesight – and the growth, reproduction and differentiation of epithelial cells. Vitamin A deficiency leads to the keratinization of the epithelium, and disorders related to the metaplasies of the genital and genitourinary systems. Conversely, vitamin D is defined as a pro-hormone and is responsible for Cahomeostasis, and thus indirectly affects the bone metabolism, bone structure, and cellular and neural functions of Ca. White muscle disease (WMD) can occur in newborn lambs, but is more commonly seen in lambs of up to 3 months of age. In this study, 30 lambs of 3 to 50-days-old from different flocks diagnosed with White Muscle Disease (WMD) were selected as research material, while the control group consisted of 8 healthy lambs. With the aim of clarifying the cause of WMD, serum fat-soluble vitamins, retinol, α-tocopherol and vitamin D3 levels were determined in 16 lambs. Gluteal and heart musclet issue samples also were taken from 30 lambs with WMD. The vitamin levels of the samples were analysed by HPLC. The levels of serum α-tocopherol, retinols, and vitamin D3 were foundto be low in the diseased animals, but only retinol (p<0.001) and α-tocopherol (p<0.0011) level differences were statistically relevant. Macroscopically, Zenker’s necrosis was determined in the heart muscles of 17 lambs, and in the gluteal and chest muscles of 6 lambs. 7 lambs displayed necrosis in both their heart and in gluteal muscles. The samples were analyzed microscopically to reach similar findings: swollen homogeneous pink muscles, pycnotic nuclei, and hyperaemic and haemorrhagic blood vessels in gluteal, chest and heart muscles. Hyaline degeneration and Zenker's necrosis, dystrophic regions in necrotic areas, cc was detected as a severe disease in lambs at an early stage of life with advanced degeneration in different muscle tissues. Deficiency of fat-soluble vitamins was also detected in the sick animals. Control group lambs had higher levels of α tocopherol and retinol (p<0.001) compared to the sick lambs. .
