“…On the other hand, similar blood concentrations of cholesterol between treatments reflect a similar energy status between animals (Table 6). Similar results are reported by Silva et al (2017) found no difference in blood concentration of insulin (1.45 vs. 1.43 μIU mL -1 ), glucose (84.3 vs. 80.6 mg dL -1 ) and, cholesterol (172 vs. 160 mg dL -1 ) in Nellore female calves submitted to different supplementation levels under grazing in the tropic.…”

The objective in this study was to evaluate the effects of supplementation levels on productive and nutritional performance and metabolic profile in suckling female calves under grazing. Forty female calves (averaging 3.5±0.06 months and 127.3±2.68 kg), and their respective dams were distributed in a completely randomized design with two treatments and twenty replicates. The treatments were 1) 4 g kg-1 body weight (BW) of supplement or 2) 6 g kg-1 BW of supplement. Forage and organic matter (OM) intake did not affect (P > 0.05) by levels of supplement, though crude protein and non-fibrous carbohydrates intake were greater (P < 0.05) by increasing supplementation level. There was no effect (P > 0.05) the supplementation levels on OM and CP digestibility. The metabolic profile of the animals was not affected (P > 0.05) by supplementation level. Average daily gain, longissimus dorsi area, fat thickness over rump of the animals did not affect (P > 0.05) by levels of supplement. However, there was trend of increasing (P=0.074) in fat thickness over loin by increase the supplementation level. Although the body growth of animals was similar (P > 0.05) between treatments, there was observed a trend of increase (P=0.064) in ratio BW:Height at the withers by increasing supplementation levels. In conclusion, increasing the supplementation level of 4 to 6 g kg-1 of BW, not improve the productive and nutritional performance and metabolic status in female calves under grazing on creep-feeding system.

“…The average levels of albumin observed in this study were slightly below those described by Kaneko et al (2014). Silva et al (2017) also found albumin levels slightly below recommendations on weaned Nellore heifers kept on pasture only, highlighting the effect of forage seasonality in the Central Brazil region that directly reflects the availability of nutrients in the diet for animal metabolism, more specifically protein.…”

Calves are susceptible to a wide variety of stressors besides the seasoning low forage availability during their weaning phase. Thus, it is ideal if they receive adequate trace mineral supplementation during this period. This study evaluated the effect of injectable trace minerals (ITM) on performance, concentration of oxidative stress enzymes, and biochemical plasmatic parameters in Nellore calves during the weaning phase and under feed restriction. A total of 30 Nellore calves were used at the age of 7 ± 1 month and 176.23 ± 21.68 kg of initial body weight (BW). These animals were allocated in Urochloa decumbens pasture for 28 days and transferred to Urochloa brizantha cv Marandu pasture for another 28 days. The treatments were: Saline (saline solution; 0.9% NaCl) and ITM (Multimin®, providing: 15 mg Cu/mL, 60 mg Zn/mL, 10 mg Mn/ mL, and 5 mg Se/mL). Both treatments were applied subcutaneously in the ratio of 1 mL/45 kg of BW. At the end of the experiment (d 56), animals were lighter than on d 0 in both treatments (P < 0.05). However, calves that received the ITM treatment presented lower body weight (P < 0.05) on d 56, compared to those in the control group. No significant difference (P > 0.05) was observed on the concentrations of oxidative stress enzymes. Moreover, no significant difference (P > 0.05) was observed in the plasmatic parameters; these were at normal range or slightly below the concentrations described for the species. We concluded that, in a feed restriction condition, the use of ITM in weaned calves did not improve performance, and the concentration of oxidative stress enzymes, and biochemistry variables. Therefore, we do not recommend using injectable trace minerals in the concentrations used in this study in animals under such stressful conditions.

“…This fact is possibly due to the greater dependence on the dam’s milk and less ruminal capacity to degrade fibre at that time. By contrast, Da Silva et al [ 20 ] did not report an increase in the serum levels of total proteins, albumins, or globulins in female calves with or without supplementation.…”

“…Such a pattern seems to indicate that both the anabolic effect and the level of protein supplement offered were not sufficient to influence the gain composition. Da Silva et al [ 20 ] and Ortega et al [ 21 ] did not observe an increase in ADG, FBW or ribeye area, although they reported an increase in FAT-R and a tendency to increase in FAT-Ld with an increase in the supplement amount.…”

Objective: This study was conducted to evaluate the effects of the provision of a protein-rich supplement on productive performance, and metabolic profile on grazing suckling female beef calves in tropical conditions during 150 d of experimentation.Methods: Fifty-six Nellore suckling female calves, and their respective dams were distributed in a completely randomised design and made to undergo two treatments as follows: UNS (without supplementation), and SUP (supplementation with 5 g/kg body weight [BW] of a protein supplement). Throughout the experiment, animal performance and metabolic profile were evaluated. Also, ureagenesis and gluconeogenesis were assessed for gene expression.Results: SUP female calves showed a higher voluntary intake (p≤0.03) of the diet components evaluated, digestibility of organic matter (p≤0.02) and microbial nitrogen production (MICN; p≤0.02) compared to UNS female calves. In its turn, serum urea nitrogen (p≤0.01) and insulin-like growth factor-1 (p≤0.03) levels and ureagenesis (p≤0.04) increased in SUP female calves compared to UNS female calves. Blood glucose and triglyceride levels were not affected by supplementation. The average daily gain (ADG) from SUP female calves was higher (p≤0.02) compared with UNS female calves. However, supplementation did not affect the body measures of the animals.Conclusion: In summary, provision of a protein-rich supplement improves the intake and nutrients digestibility, ADG and final BW and increases metabolic indicators of the protein status in grazing suckling female beef calves in tropical conditions.
