“…Coincidently with the present results, Griffiths et al (2007) found no effect of supplementation on claw hardness or on the incidence of claw disorders. Even if a beneficial effect of the mineral supplementation was observed in the locomotion score, these scores of locomotion are not clinically relevant.…”

“…Moreover, in most experiments, supplementation starts in the prepartum. The experiment most comparable to ours is the one by Griffiths et al (2007) where grazing primipa- rous and multiparous cows were used. However, the authors do not provide information about the responses of primiparous versus multiparous cows.…”

“…The discrepancies may be explained by the differences in experimental models (stabulation vs. grazing conditions), different composition of the diets and the composition and amount of the mineral supplementation. Griffiths et al (2007) reported an increase in the production of milk in supplemented grazing cows. However, the supplementation period used in that experiment exceeded by far the treatment period of the present study.…”

The effect of complexed trace minerals supplementation on productive, reproductive and metabolic variables during early postpartum of grazing primiparous dairy cows =) was investigated. Pasture-fed Holstein heifers were offered (supplemented group; SG, n = 60) or not (control group; CG, n = 60) a commercial trace mineral supplement during the first 90 days of lactation. Milk production and composition were determined monthly. Reproductive function was evaluated by calving-first service interval, number of services per conception, and pregnancy rates. Non-esterified fatty acids, β-hydroxybutyrate, insulin, and insulin-like growth factor-1 were determined on blood samples collected on days postpartum -7 ± 4, 30 and 60. Supplementation did not affect milk production or its composition, except for fat percentage that tended to be higher in SG than CG. Calving-first service and calving-conception intervals were shorter in SG than CG but number of services per conception and pregnancy rates did not differ between treatments. No lameness was observed during the period evaluated and although a beneficial effect of SG was found in locomotion score, it was not clinically relevant (scores 1-2). Metabolites and hormones concentrations did not differ between treatments. Organic trace mineral supplementation had a transient beneficial effect on milk composition on the intervals from calving to first service and from calving to conception, with no changes in metabolic and endocrine profiles during the transition period primiparous dairy cows on grazing conditions. Additional key words: dairy cows; Holstein heifers; metabolic-endocrine profile microminerals; transition. ResumenEfecto de la suplementación con minerales orgánicos traza durante el postparto temprano sobre la composición de la leche y los perfiles metabólicos y hormonales en novillas de leche Se investigó el efecto de la suplementación con complejos de minerales traza sobre variables productivas, reproductivas y metabólicas durante el postparto temprano en vacas lecheras primíparas en pastoreo. Novillas Holstein (n = 120) fueron suplementadas (SG) o no (grupo control; CG) con un preparado comercial de minerales traza durante los primeros 90 días de lactación. La producción de leche y su composición se determinaron mensualmente. La actividad reproductiva fue evaluada por el intervalo parto-primera inseminación artificial (IA), el número de servicios por concepción y la tasa de gestación. Se determinaron los ácidos grasos no esterificados, el β-hidroxibutirato, la insulina y el factor de crecimiento similar a la insulina-1 en muestras de sangre tomadas los días postparto -7 ± 4, 30 y 60. La suplementación no afectó la producción de leche ni su composición, excepto por una tendencia del porcentaje de grasa a ser mayor en el SG que en el CG. Los intervalos parto-primera IA y parto-concepción fueron menor en SG que en CG, pero el número de IA por concepción y las tasas de gestación no fueron diferentes entre los dos grupos. No

“…Average Se for animals fed organic and inorganic sources during pre-partum and lactation (4.7 and 6.6 mg/day, respectively) was slightly higher than the recommendations of the NRC (2001) (4.3 and 5.7 mg/day, respectively). Studies on the supply of different sources of micro minerals (Griffiths et al, 2007;Kinal et al, 2007a;Siciliano-Jones et al, 2008) did not estimate total nutrient intake.…”

-The present study was carried out with the objective of evaluating the effects of feeding dairy cows with organic or inorganic sources of zinc (Zn), copper (Cu) and selenium (Se) on blood concentrations of these minerals, blood metabolic profiles, nutrient intake and milk yield and composition. Nineteen Holstein cows were selected and randomly assigned to two groups for receiving organic (n = 9) or inorganic (n = 10) sources of Zn, Cu and Se from 60 days before the expected date of calving to 80 days of lactation. Samples of feed, orts and milk were collected for analysis. Body condition score (BCS) was determined and blood samples were collected for analysis of Zn, Cu and Se concentrations, as well as for metabolic profile.Supplying organic or inorganic sources of Zn, Cu, and Se did not affect dry matter and nutrient intake, blood metabolic profile, milk yield and composition, plasma concentration of these minerals, and BCS or change the BCS in cows from 60 days before the expected date of calving to 80 days of lactation. An effect of time was observed on all feed intake variables, plasma concentrations of Zn and Se, milk yield, milk protein content, BCS and change in BCS.
