Effect of Supplemental Biotin on Performance of
نویسنده
چکیده
Biotin is a B-complex vitamin that is essential for cattle. However, for several decades very little research was published on the effects of biotin in cattle. This lack of interest was probably caused by the inability to produce clinical biotin deficiencies in functioning ruminants and by the consensus that adequate biotin was in normal feedstuffs or was synthesized by bacteria in the rumen and lower intestines. In the last few years, renewed interest in on the effects of supplemental biotin for cattle has developed. Most of the recent research has centered on the effects of biotin on hoof health of dairy cows (Bergsten et al., 1999; Fitzgerald et al., 2000; Midla et al., 1998). All these studies reported a positive response on some measure of hoof health to supplemental biotin. Biotin, however, is involved in many metabolic pathways directly involved with milk synthesis. Because of the ever increasing productivity of dairy cows, the effects of supplemental biotin on milk production and metabolism of dairy cows should be studied.

Supplemental biotin for swine. I. Influence on feedlot performance, plasma biotin and toe lesions in developing gilts.
Three trials, utilizing a total of 240 crossbred gilts, were conducted to study the influence of 0 (NB) or 220 (SB) microgram supplemental biotin/kg of diet on feedlot performance, plasma biotin and development of toe lesions in developing gilts. Corn-soybean meal diets were fed from weaning to 92 kg body weight. Gilts were housed on expanded-metal floors to 50 kg body weight and on partially s...

The objective of study was to determine the effects of supplemental biotin on lactation performance and hoof quality in dairy cows. Forty-five multiparous Chinese Holstein dairy cows (4076 d in milk) were randomly divided in three groups according to parity, previous lactation milk yield and days in milk. The experimental diets were identical for three treatments except for the level of biotin:...
