Four gilts, sisters from one litter, aged 70 days and weighing 20-24 kg, were used for a trial. Two experimental gilts (P) were administered an experimental feed mixture containing phenylmercury chloride (40 mg/kg). Two control gilts (K) were fed the same mixture but without phenylmercury chloride. P gilts began to lag behind in their growth from day 60 of the experiment, they manifested nonphysiological postures (dog's sitting posture), paresis of hind limbs and uncoordinated movements. P gilts had cloudy, orange-brown urine from day 70 and from day 75 they began to suffer from diarrhoea. Mercury (Hg) contents in urine and blood serum of P gilts were irregularly variable: urine 0.58-2.15 mg/l, blood serum 0.02-0.37 mg/l. Hg content in excrements of P gilts fluctuated from 23 to 26 mg/kg. Vitamin A concentrations in blood serum and liver decreased in P gilts. Phenylmercury chloride feeding caused mutagenic changes in peripheral lymphocytes of P gilts (an increase in the number of aberrant cells from 2-3% to 8-9%) and reduced IgA, IgM and IgG immunoglobulin levels in blood serum. Pathological lesions were observed in the colon, kidneys and liver. None of the above-mentioned changes were observed in K gilts. Increased resistance to the negative effects of Hg was found in one experimental gilt. In comparison with K gilts, Hg concentrations in P gilts after 130 days of the experiment increased as follows: 427 times in kidneys, 333 times in liver, 106 times in guts, 71 times in pancreas, 53 times in ovaries, 50 times in muscles, 47 times in bristles and 16 times in the brain.(ABSTRACT TRUNCATED AT 250 WORDS)

Retinol (vitamin A), alpha-tocopherol (vitamin E), and Zn are micronutrients essential for health and performance. We determined the effects of parturition, lactation, and periparturient Ca status on plasma retinol, alpha-tocopherol, and Zn in 18 Jersey cows during the 2 wk before and after parturition. Six cows developed clinical milk fever. Prepartum plasma concentrations of retinol, alpha-tocopherol, and Zn decreased progressively in all animals. A nadir was reached at 1 d postpartum when concentrations declined to 38, 47, and 67%, respectively, of prepartal baseline concentrations. Plasma Zn returned to baseline concentrations within 3 d of calving, and plasma alpha-tocopherol returned toward baseline about 10 d after calving. Plasma retinol remained below baseline concentrations throughout the first 2 wk of lactation. The decline in plasma Zn observed at calving was more severe in cows with milk fever (parturient paresis) than in cows without milk fever. The decrease in plasma retinol and alpha-tocopherol observed at parturition was similar in cows with or without milk fever. These data document an acute decline in plasma retinol, alpha-tocopherol, and Zn in the immediate periparturient period and indicate that the decline in plasma Zn is more severe in cows with milk fever.

Vitamin A toxicosis and vitamin E deficiency was diagnosed in a commercial rabbit-breeding colony and was associated with reproductive abnormalities, abortions, and poor survivability of kits in the breeding colony. Paresis and muscular dystrophy were noted in juvenile rabbits. Another group of New Zealand White rabbits from the same commercial colony was used to assess the effect of vitamin E-based therapy on clinical signs, reproduction, and vitamin A and E serum and liver levels. Blood samples were taken before and after dietary changes and vitamin E therapy. Serum vitamin E remained low after feeding a diet containing the recommended levels of vitamin E. Administration of vitamin E for 2 weeks lowered the serum vitamin A levels and increased the vitamin E serum and liver levels. In conclusion, vitamin E therapy appears to be an effective treatment for hypervitaminosis A.
