The aim was to evaluate the effect of different feed additives on intake, performance, and fecal consistency index (FCI) dairy calves from 6-60 d age its residual 15 after weaning. Fifty Holstein (38 ± 1.0 kg BW) were fed 5 L/d milk plus starter until weaning, corn silage concentrate treatments were: control (CON), monensin (MON; 30 mg/kg starter), probiotic E. faecium (PROB; 70 essential oils (EO; 300 or PROB + EO (EOPROB). Fecal score dry matter intake (DMI) measured daily, animals weighed...

The objective of this experiment was to assess ruminal outflow and apparent total-tract digestibility using digesta samples from 3 sites (reticulum, omasum, abomasum) marker methods (single marker: indigestible NDF [iNDF; sample without separation]; double iNDF + Co-EDTA [filtered sample]; triple ytterbium [Yb] acetate centrifuged]) in bulls fed corn silage sugarcane-based diets. Eight crossbred (Holstein × Zebu) (353 ± 37 kg BW; 24 1 mo age) with abomasal cannulas were randomly distributed...

This experiment was carried out to study the carcass characteristics, chemical composition and fatty acid profile of Longissimus muscle (LM) bulls (10) steers (17) finished in a pasture system.Animals (1/2 Zebu vs. 1/2 Aberdeen Angus) were fed system (Hermatria altissima) with supplement soybean meal, cracked corn, urea, limestone mineral salts, twice day.Both animal groups slaughtered at 27 months age, an average 508.88 kg live weight.Final weight, hot weight texture similar (p>0.05)...
This experiment was carried out to evaluate performance and carcass characteristics of 40 crossbred young bulls (Zebu×European) finished in a feedlot under two roughage sources (Bermuda grass hay or sorghum silage) with without the addition yeast (Saccharomyces cerevisae).The were 20 months old, their initial average weight 356 kg they allocated into four groups ten animals.The experimental diets Bermuda grass, grass+yeast, silage +yeast.Animal not influenced by source addition.The daily...
This study was conducted to determine the effect of breed on chemical composition first (PUR1) and second (PUR2) generations Purunã young bulls, compare both with different genetic groups: CAN vs. ANG; CAR; CHA CAR.Thirty bulls were used.The animals from PUR2 CAR groups featured higher (p<0.05)moisture percentage in comparison PUR1, ANG groups.The moisture similar (p>0.05) between animals.The same observed among CAR, animals.There no difference (p>0.05)among for ash, total lipids...

Nutrient requirements in cattle are dependent on physiological stage, breed and environmental conditions. In Holstein × Gyr crossbred dairy heifers, the lack of data remains a limiting factor for estimating energy protein requirements. Thus, we aimed to estimate heifers raised under tropical Twenty-two (½ ½ Gyr) with an average initial BW 102.2 ± 3.4 kg 3 4 months age were used. To requirements, comparative slaughter technique was used: four animals assigned reference group, slaughtered at...
