Fat in lactation rations: review.

Recent research has demonstrated the effectiveness of added fat in diets to maintain milk production and fat percent. Much of the earlier work which indicated that fat affects digestion negatively may not be applicable because of great differences in the nature of diets and fats fed and especially in total feed intake. Nevertheless, much remains to be learned about interactions of fat, fiber, calcium, and rumen microorganisms if feeding of fat is to be maximized. The uniquely high acidity in the duodenum combined with detergent action of bile acids, lysolecithin, and fatty acids causes saturated fatty acids to be more digestible in ruminants than in nonruminants. Large quantities of added dietary fat increase concentrations in plasma of very low density lipoprotein triglyceride which increases their uptake by the mammary gland with inhibition of short chain fatty acid synthesis and consequent changes in milk fatty acid composition. In some cases, secretion of milk fat is increased. Current research and practice demonstrate that 3 to 5% fat may be added to diets for lactation to increase energy intake of high-producing cows and/or to reduce starch feeding, thereby increasing the ratio of forage to concentrate to prevent depression of milk fat.

After-image transfer--evaluation of short-term treatment.

The records of treatment by the after-image transfer method of 21 children, mainly with strabismus amblyopia, were examined to evaluate the acuity improvement in the short term. There was no significant improvement in 15 cases. In several other patients, an immediate response to the after-image method occurred, but these patients' binocular vision and acuity had deteriorated following previous improvement achieved by other orthoptic methods.

The foveal reflex in amblyopia.

The relative brightness of the foveal reflex between amblyopic eyes and their fellows was examined. Differences in reflex appearances were found in some patients but not in others. Equal appearance of the foveal reflexes does not eliminate the possibility of amblyopia, nor is there a difference in appearance related to the degree of amblyopia.
