AB: The effect of biotin supplementation on turkey breeder hen performance was examined in two experiments. A corn-soybean meal-based breeder diet was supplemented with biotin to provide a low (.178 mg/kg) and high (.75 mg/kg) level of dietary biotin. The diets were fed to female-line hens (Nicholas strain) starting at time of light stimulation (31 and 30 wk of age for Experiments 1 and 2, respectively) for 27 wk. Each diet was fed to four replicate pens of 25 hens each. In Experiment 1, egg production and hatchability of fertile eggs from hens fed the high level of biotin was significantly greater (P <.05) during 50 to 54 wk of age. Egg production and hatchability were improved by 22 and 10%, respectively, from 50 to 54 wk of age. In Experiment 2, reproductive performance was unaffected by biotin level during 33 to 57 wk of age. The higher level of dietary biotin seemed beneficial in supporting later reproductive performance in one of two experiments.

AB: The effects of maternal dietary biotin deficiency on hamster embryos were examined by adding different amounts of avidin (0, 10, 50, 100 or 1000 mg/ kg diet) to a semipurified commercial diet during the entire period of gestation. On d 10 of gestation, reduced dietary biotin resulted in a high incidence of resorbed and dead embryos. In addition, both the crown-rump length and head length of dietary biotin-deficient embryos were lower, and their digit development was retarded. These embryos were characterized by pericardial cavity enlargement (40%) and zig-zag closure line of the neural tube (44%). Some embryos exhibited abnormalities of the craniofacial region and tail. On d 14 of gestation, embryonic growth retardation, morphological abnormalities and skeletal defects were seen in the dietary biotin-deficient group (fed 100 mg avidin/kg diet). The striking abnormalities were cleft palate, micromelia, micrognathia and rib deformities in approximately 10% of the fetuses. Histological examination of the placentae revealed some differences in the spongiotrophoblast and labyrinth layers between the control and dietary biotin-deficient groups. The teratogenic effect of dietary biotin deficiency previously observed in mice was confirmed in hamsters.

AB: The ability to detect biomolecules in single cells is important in order to fully understand the processes by which many biochemical events occur. To that end, we have developed a bioluminescence binding assay capable of measuring the intracellular biotin content of individual cells. The assay depends on competition between an aequorin-biotin conjugate (AEQ-biotin) and free biotin within the oocytes for binding sites on the protein avidin. The assay is performed by microinjecting each component into the oocytes and following the resulting bioluminescence within the oocyte upon triggering of aequorin. Results obtained using sea urchin oocytes show that the assay performed within the cells behaves in a manner consistent with assay theory. Using the assay, the individual biotin content of the oocytes is an average of approximately 20 amol. To our knowledge, this is the first reported multicomponent binding assay to be performed inside an intact single cell.

AB: We previously showed that the incidence of external malformations induced by biotin deficiency did not differ either between XO and XX dams or between XO and XX fetuses. To clarify whether this phenomenon is specific to biotin deficiency or more generally associated with other teratogens, we examined whether XO mice are more susceptible to teratogenic effects of hypervitaminosis-A. Pregnant XO and XX mice were given an excessive vitamin A diets (1.0 to 1.5 x 10(6) IU/kg) from days 0 to 17 of gestation. Maternal hypervitaminosis-A produced a high incidence of external malformations (65 to 80%), skeletal anomalies (33 to 47%), and variations (99 to 100%) in the fetuses. However, there is no difference in their incidences between XO and XX dams or between XO and XX fetuses. Together with previous findings, this suggests that developmental stability of the mouse embryo is not affected by missing of one whole X chromosome even with exposure to teratogens.

Biotin supplementation had no beneficial effect (P greater than .10) on 107-d sow weight, sow weight at weaning, weaning to estrus interval, foot lesion score, hair loss score, structural soundness score, number of pigs born, number and percentage of pigs born alive or number and percentage of pigs alive at 21 d of age. Biotin supplementation had no effect (P greater than .10) on pig growth or mortality to 21 d of age. These data do not support the concept that biotin supplementation of sow diets is needed.

AB: A cooperative experiment to evaluate biotin addition to sow diets was conducted at three research stations using 303 litters. Primiparous and multiparous sows (overall average parity 2.8) were fed a 14% CP corn-soybean meal diet (140 micrograms/kg biotin), with or without supplemental biotin (330 micrograms added biotin per kg feed), throughout gestation and lactation. As many sows as possible were fed their respective diets through three successive parities. During gestation, sows were given from 1.82 to 2.27 kg of feed per day, depending on environmental conditions; during lactation sows had ad libitum access to feed. Supplemental biotin had no effect (P greater than .35) on sow weights at breeding, at d 109 of gestation, at farrowing or at weaning. No differences were found in litter size at birth (P greater than .18), but at d 21 of lactation, sows fed the diet containing supplemental biotin had larger litters than sows fed the unsupplemented diet (9.4 vs 8.7 pigs, respectively; P = .01). Pig weights at birth and d 21 of lactation were not affected (P greater than .20) by dietary treatment. Biotin supplementation did not affect (P greater than .28) the length of the interval from weaning to estrus. No evidence was found that feet cracks or bruises were reduced by biotin supplementation. The results indicate that biotin supplementation of a corn-soybean meal diet during gestation and lactation increased the number of pigs at d 21 of lactation, but it did not decrease the incidence of foot lesions.

AB: Data from 116 females previously fed a corn-soybean basal diet with 0 or 220 micrograms supplemental biotin/kg during growth and development were used to study the influence of 0 (NB) or 440 (SB) micrograms of supplemental biotin/kg to corn-(C) or wheat-(W) based diets for gilts and sows housed in total confinement. Reproductive performance through four parities (total of 245 litters) and various sow and pig biochemical criteria were evaluated. Females fed W diets were older (P less than .07) at first estrus, farrowed litters that were lighter weight (P less than .01) at birth and that contained fewer (P less than .05) total and live pigs compared with females fed C diets. Biotin supplementation did not significantly influence (P greater than .10) farrowing and lactation performance; however, after the first parity, total and live pigs/litter at farrowing tended to be larger for SB females. Conception rate at first estrus postpartum was increased (P less than .07) by 9% and the average weaning to estrus interval was reduced (P less than .05) from 14.5 to 10.2 d with SB. Biotin supplementation increased (P less than .001) the biotin content of sow plasma, milk and liver, while sow liver pyruvate carboxylase activity was not altered (P greater than .10). Pigs farrowed by SB females had three- and fivefold higher (P less than .001) levels of plasma biotin at birth and 14 d of age, respectively; however, liver biotin levels at birth were not different (P greater than .10) for pigs from NB and SB females.(ABSTRACT TRUNCATED AT 250 WORDS)

AB: For many years, it was believed that supplemental biotin was not needed in swine diets because of the wide distribution of biotin in feedstuffs used in the formulation of swine diets, and because of the known synthesis of biotin by the animal's intestinal microflora. However, interest in biotin nutrition for swine was rekindled in the mid-1970s when several field reports indicated a biotin deficiency in swine that was responsive to biotin supplementation in many cases. Results from university research are accumulating, especially from long-term sow studies (three to four parities), which suggest that supplemental biotin will improve litter size, conception rate, weaning-to-estrus interval, toe lesions, and haircoat condition. Milk biotin concentration and plasma biotin concentration of sows and piglets were also elevated when supplemental biotin was fed. Using presently available feedstuffs and under modern swine production conditions, a marginal biotin deficiency is possible. Swine producers experiencing poor reproductive performance in their sow herds, associated with excessive loss of hair and severe foot lesions, should evaluate the biotin content of their sow diet and consider supplemental biotin.

AB: Eighty female pigs were fed from 25 kg liveweight either basal diets calculated to provide 32 micrograms available biotin/kg (control diet) or basal diets supplemented with 350 micrograms biotin/kg. Reproductive performance was studied over four parities. Sows receiving supplementary biotin returned to oestrus 2.9 +/- 1.7 and conceived 6.1 +/- 1.4 days sooner than controls (P less than 0.05). Of those sows receiving supplementary biotin, more returned to oestrus and conceived within 10 days of weaning (83.2 per cent v 74.6 per cent and 80.6 per cent v 71.8 per cent respectively) and fewer were treated for anoestrus (7.3 per cent v 17.0 per cent) than those on the control diet. Supplementing diets increased the annual productivity of sows completing four parities by 1.42 +/- 1.02 pigs/sow/year (P less than 0.05) and increased the total weight of weaner produced/sow/year by 17.3 +/- 7.4 kg (P less than 0.05). It was concluded that the majority of commercial dietary formulations would require supplementation with biotin in order that sows may express their full reproductive potential.

AB: At a pig breeding farm with 130 sows, the culling rate in respect of the young replacement stock was more than 50% and was in particular caused by lameness. The effect was investigated of d-biotin supplementation of the feed on culling percentage, reproduction, claw lesions and lameness of gilts (young replacement stock) and sows, and piglet mortality. The young pigs were divided into a group of 23 young replacement pigs aged 2.5 months (12 controls and 11 treated) and a group of 47 gilts aged 7 months (23 controls and 24 treated). Both treatment groups received feed supplemented with 1250 mcg/kg d-biotin. Furthermore, all sows received feed supplemented with 500 mcg/kg d-biotin. The basic feed contained 175 mcg/kg biotin, of which about 100 mcg/kg was biologically available biotin. Biotin supplementation resulted in an increase in the plasma biotin levels from the critical deficiency level of about 50 ng/100 ml to about 300 ng/100 ml in young replacement stock, to about 179 ng/100 ml in the gilts, and to about 123 ng/100 ml in the sows. After 2.5 months of biotin supplementation the claw lesion score of the gilts had decreased by 28% (p less than 0.001). In the young replacement stock a reduction of the claw lesion score by 52% (p less than 0.001) was found after 4 months supplementation. The effect of biotin supplementation was greatest in the soft heel region (improved by 35%) and somewhat less on the claw wall (improved by 23%). After 11 months' supplementation with 500 mcg/kg biotin the effects on production performance of the sows compared to the previous year can be summarized as follows: --the overall culling rate dropped from 54.0% tot 30.8%, --the culling rate due to lameness decreased by 11% from 25% to 14%, --the culling as a result of 'insufficient production' was reduced from 11% to 4%, --a positive trend in piglet mortality was observed (17.7% compared to 19.2%). An increase of the biotin content of Dutch pig feeds and regular monitoring of its biotin content would appear to be advisable.

AB: The effect of biotin supplementation of diets for breeding sows was investigated in a herd where the sows exhibited symptoms resembling those of experimentally induced biotin deficiency. Twenty sows received diets supplemented with 250 mcg D-biotin per kg in pregnancy and 150 mcg D-biotin per kg in lactation. Over a six month period the supplemented sows showed a 28 per cent reduction in the number of foot lesions recorded. Twenty-two control sows showed no reduction in foot lesions. Sows on the supplemented diets produced more piglets at birth than controls, but the differences were not significant. However, second parity supplemented sows did produce significantly more live pigs than controls (1-64 +/- 0-77, P less than 0-05). The weaning to remating interval was significantly reduced from 15-31 +/- 2-85 days in the controls to 6-23 +/- 2-85 days in the supplemented sows (P less than 0-05) and the percentage of sows exhibiting oestrus within seven days of weaning was increased from 56 per cent to 89 per cent.

AB: Five floor pens with 14 Leghorn-type breeder hens each, in their 4th month of production, and 2 males per pen were fed a practical-type breeder diet composed largely of soybean meal and milo supplemented with unidentified hatchability factor sources and adequate levels of vitamins and minerals. Five additional pens were fed an identical ration supplemented with biotin at a level of 550 mcg./kg. of diet. Treatment was for a period of 7 months. A 3% improvement in production was obtained by biotin (550 mcg./kg.) supplementation, which was found to be highly significant (P less than or equal to .005) by chi-square analysis. A slight improvement was noted for feed efficiency. Biotin supplementation had no effect on egg size or adult livability. Fertility and hatchability were both significantly improved by biotin supplementation. Fertility and hatchability differences were found to be highly significant by chi-square analyses. Increased hatchability was due to a decreased number of early dead, late dead, and pipped embryos that failed to hatch.
