| Abstract: | Two groups of five female store pigs, weighing an average of 60 kg at the start of the experiment, were given either 1 or 10 mg metallibure zinc complex (SUISYNCHRON) per kg body weight once daily for six months, in the form of a 2% talcum premix added to concentrates. Clinical inspection, weight gain, haematological findings, blood sugar, serum transaminases, properties of urine and faeces, carcass examination and histological study (internal organs, endocrine glands, skeletal muscle) showed that the 1 mg/kg dosage had no toxic effect. The 10 mg/kg dosage resulted in considerable depression in appetite and some apathy in the pigs, but there was no evidence of a toxic effect. |
