Effect Of Long-Acting Penicillin And Levamisole® On Gain And Health Of Stressed Calves, F.K. Brazle Jan 1992

Effect Of Long-Acting Penicillin And Levamisole® On Gain And Health Of Stressed Calves, F.K. Brazle

Kansas Agricultural Experiment Station Research Reports

Two studies were conducted to determine the effect of long-acting penicillin and/or levamisole injected at arrival or levamisole injected on day 1 and/or day 7 on the health and gain of newly received, highly stressed, light weight calves. Levamisole injected at arrival reduced (P<.05) sickness of newly arrived calves during the first 5 days. However, it did not reduce overall sickness during the receiving period. Long-acting penicillin injected at arrival did not reduce sickness, but did improve (P<.05) gain of calves during the growing period. The combination of levamisole and long-acting penicillin or the combination of levamisole on day 1 and day 7 did not reduce morbidity in these highly stressed calves.

A 25 d growth trial utilizing 198 pigs was conducted to determine the influence of fumaric acid and calcium formate on starter pig performance. At weaning (19 d of age and 11.9 lb), pigs were blocked by weight and allotted to one of three dietary treatments: a control diet without acid addition or diets containing 1.5% fumaric acid or 1.5% calcium formate. Adding calcium formate to the diet had no influence on average daily gain (ADG), average daily feed intake (ADFI), or feed efficiency (F/G). Pigs fed the diet containing fumaric acid had improved feed efficiency during the first 2 …

Kansas Agricultural Experiment Station Research Reports

A total of 318 pigs was used in a 25-d growth trial to determine the influence of high levels of B-vitamins on starter pig performance. At weaning (l6-d of age), pigs were blocked by weight to one of six dietary treatments based on B-vitamin level. The negative control diet contained the standard KSU B-vitamin additions. The next four diets contained vitamin B12, riboflavin, pantothenic acid, or niacin at lOx the level recommended by NRC (1988). The positive control diet contained all four vitamins at 10 x the levels suggested by NRC (1988). B-vitamin inclusion rate did not influence average daily …
