“…decreased ruminal biohydrogenation intermediates of milk fat (Enjalbert et al, 2008), which is in agreement with our results, where these FA are decreased in both colostrum and milk fat by B 8 supplementation. Intermediates of ruminal biohydrogenation are produced during the transformation process of dietary UFA to SFA by ruminal bacteria (Jenkins et al, 2008) and end up in milk.…”

Biotin (B 8 ), folate (B 9 ), and vitamin B 12 (B 12 ) are involved in several metabolic reactions related to energy metabolism. We hypothesized that a low supply of one of these vitamins during the transition period would impair metabolic status. This study was undertaken to assess the interaction between B 8 supplement and a supplementation of B 9 and B 12 regarding body weight (BW) change, dry matter intake, energy balance, and fatty acid (FA) compositions of colostrum and milk fat from d −21 to 21 relative to calving. Thirty-two multiparous Holstein cows housed in tie stalls were randomly assigned, according to their previous 305-d milk yield, to 8 incomplete blocks in 4 treatments: (1) a 2-mL weekly i.m. injection of saline (0.9% NaCl; B 8 −/ B 9 B 12 −); (2) 20 mg/d of dietary B 8 (unprotected from ruminal degradation) and 2-mL weekly i.m. injection of 0.9% NaCl (B 8 +/B 9 B 12 −); (3) 2.6 g/d of dietary B 9 (unprotected) and 2-mL weekly i.m. injection of 10 mg of B 12 (B 8 −/B 9 B 12 +); (4) 20 mg/d of dietary B 8 , 2.6 g/d of dietary B 9 , and 2-mL weekly i.m. injection of 10 mg of B 12 (B 8 +/B 9 B 12 +) in a 2 × 2 factorial arrangement. Colostrum was sampled at first milking. and milk samples were collected weekly on 2 consecutive milkings and analyzed for FA composition. Body condition score and BW were recorded every week throughout the trial. Within the first 21 d of lactation, B 8 −/B 9 B 12 + cows had an increased milk yield by 13.5% [45.5 (standard error, SE: 1.8) kg/d] compared with B 8 −/B 9 B 12 − cows [40.1 (SE: 1.9)], whereas B 8 supplement had no effect. Even though body condition score was not affected by treatment, B 8 −/B 9 B 12 + cows had greater BW loss by 24 kg, suggesting higher mobilization of body reserves. Accordingly, milk de novo FA decreased and preformed FA concentration increased in B 8 −/B 9 B 12 + cows com-pared with B 8 −/B 9 B 12 − cows. In addition, cows in the B 8 +/B 9 B 12 − group had decreased milk de novo FA and increased preformed FA concentration compared with B 8 −/B 9 B 12 − cows. Treatment had no effect on colostrum preformed FA concentration. Supplemental B 8 decreased concentrations of ruminal biohydrogenation intermediates and odd-and branched-chain FA in colostrum and milk fat. Moreover, postpartum dry matter intake for B 8 + cows tended to be lower by 1.6 kg/d. These results could indicate ruminal perturbation caused by the B 8 supplement, which was not protected from rumen degradation. Under the conditions of the current study, in contrast to B 8 +/B 9 B 12 − cows, B 8 −/ B 9 B 12 + cows produced more milk without increasing dry matter intake, although these cows had greater body fat mobilization in early lactation as suggested by the FA profile and BW loss.

“…Zimmerly and Weiss [6] found that milk production and milk protein production increased linearly with the inclusion of 10 or 20 mg of biotin/cow/day in early lactation. Biotin improved milk production in multiparous but not primiparous cows in early lactation in another study [7]. Milk production was not altered in another early lactation study [8], indicating outcome might be related to factors such as yield, DIM or parity.…”

Results from 4 switchback field trials involving 608 cows were combined to assess the effects of a protected B vitamin blend (BVB) vs 10 mg of unprotected biotin upon milk yield (kg), fat %, protein %, fat yield (kg) and protein yield (kg) in primiparous and multiparous cows. Trials consisted of 3 DHIA periods executed in the order control-test-control. Cows from 45 to 300 days in milk (DIM) at the start of the experiment that were available for all 3 periods were included in the analysis. No diet changes other than the substitution of 3 grams/cow/day of the BVB for 10 mg of biotin during the test period occurred. Results from the two control periods were compared to results obtained during the test period by individual cow using a paired T test. Results for all cows showed that the provision of the BVB resulted in increased (P < 0.05) milk, fat percentage (%), protein %, fat yield and protein yield. Analysis by age revealed that milk production and milk protein yield were only improved in mature cows. Milk production had a negative effect upon the magnitude of the increase in milk components. The change in milk yield was greatest in early lactation and declined with DIM. Protein % and fat % increased with DIM in mature cows, but not in first lactation cows. Differences in fat yields between test and control feeding periods did not change with DIM, but the improvement in protein yield in mature cows declined with DIM. These results indicate that the BVB provided economically important advantages throughout lactation beyond those witnessed with biotin, but expected results would vary with cow age and stage of lactation.

“…La biotina es la vitamina que más se ha estudiado por su efecto benéfico en la salud de la pezuña (Mülling et al, 1999) y diversas investigaciones han demostrado que el suplementar 20 mg de esta vitamina por día aumentó la producción de leche (Chen et al, 2011;Enjalbert et al, 2008;Lean & Rabiee, 2011), lo cual difiere con los resultados obtenidos en la presente investigación, situación que pudo deberse a que la dosis utilizada en el presente estudio fue la mitad (9,6 mg día -1 ) de la dosis comúnmente usada (20 mg día -1 ); ya que se considera que, al estar recubierta, va a llegar al intestino delgado en su totalidad y a que la mayoría de estudios consultados se llevaron a cabo en vacas altamente productoras de la raza Holstein y en sistemas de estabulación completo.…”

Introducción. Los requerimientos de vitaminas B en rumiantes son satisfechos por su capacidad de síntesis a nivel ruminal. El mejoramiento genético, los avances en nutrición animal y los altos niveles de producción actuales, puede hacer que los animales no estén llenando sus requerimientos. Objetivo. Evaluar el efecto que tiene el uso de un complejo de vitaminas del grupo B sobre la producción láctea y el metabolismo de vacas lecheras en pastoreo. Materiales y métodos. Durante el segundo semestre del 2017, se utilizaron treinta vacas Jersey divididas en dos grupos que se mantuvieron durante dos periodos experimentales de 30 días. Durante el primer periodo de un mes, los animales del primer grupo recibieron 3,0 g diarios de un complejo de vitaminas B, mientras que los animales del otro grupo recibieron un placebo y para el periodo 2 se intercambiaron los tratamientos. Se midió la producción y composición láctea durante todo el periodo. Se midieron variables químicas como glucosa, betahidroxibutirato, aspartato amino transferasa, nitrógeno ureico y albúmina en sangre. Resultados. No se presentaron diferencias significativas (p>0,05) con respecto a la producción láctea. En el periodo 1, el grupo suplementado produjo 15,8 l por día; mientras que el grupo control produjo 16,1 l. Las concentraciones de grasa, proteína y lactosa en el primer periodo fueron de 5,0, 3,5 y 4,4 %, respectivamente. En el periodo 2, la producción láctea fue de 14,1 y 13,7 l para el grupo suplementado y no suplementado, respectivamente. En ningún periodo se observaron diferencias significativas (p>0,05) para los parámetros de química sanguínea analizados. La concentración de glucosa fue superior a 40 mg dl-1 y la concentración de betahidroxibutirato fue superior a 2,0 mmol l-1. Conclusión. Suplementar vacas Jersey con un complejo de vitaminas B de sobrepaso no mostró ventaja alguna con respecto a las variables productivas evaluadas.
