The post-weaning phase is a critical period in pig growth. The transition from sow milk to solid plant or animal proteins together with the physiological development of the intestinal tract can sometimes lead to digestive disorders depressing growth and impacting upon the lifetime performance of the pig herd. Lowering feed protein level or changing the type of protein offered appears as a practical solution to decrease the incidence and severity of digestive disorders leading to diarrhoea. It is crucial that in reducing crude protein levels that the balance of amino acids are maintained to meet the pigs requirement for growth. Fishmeal is often used in diets as a source of protein and amino acids. It also is said to be an aid to palatability. The objective of this experiment was to evaluate the performance of post-weaned piglets offered diets that differed in crude protein content and in protein source from weaning until 43 days post-weaning.
Weaning is a considerable challenge to the young piglet and represents the beginning of a critical period in its life. It is also the period which has a significant effect upon both short- and long-term growth and development. Rapid early growth results in higher and more efficient growth in the subsequent growing and finishing periods. Indeed, it is a common commercial experience that the ability to produce quality lean carcases from fast-growing modern genotypes is enhanced by rapid post-weaning growth. The objective of the current trial was to measure the performance and growth potential of modern pig genotypes in the 5-week post-weaning period, when offered non-limiting diets under commercial conditions.
Changes in anticonvulsant serum levels during intercurrent illness may cause toxicity or decreased seizure control in children with epilepsy. We studied prospectively the effect of intercurrent illness and its treatment in 111 children being treated with AC monotherapy. Free fraction and total serum AC levels were determined when the child was well, on the fifth day of any illness with fever and one month after recovery. There were 55 episodes of febrile illness in 39 children during the study period. Twelve illnesses were associated with significant increases or decreases in serum AC levels; 7 children became clinically toxic; 1 child had increased seizures during illness. The mechanisms of AC level changes appeared to include interaction with antibiotics, with antipyretics or with viral illness. Amoxycillin and acetaminophen did not appear to interact with the AC's used. Physicians caring for children with epilepsy should be aware of the frequency and complexity of potential interactions between intercurrent febrile illness and anticonvulsant medication.
