“…With respect to the time expended at the trough, as reported by Benatti et al (2012) and Sichonany (2012), no differences were observed (P>0.05) between the supplementation frequencies. Signoretti et al (2012), by contrast, found that animals remained longer at the trough when the frequency of supplementation was reduced.…”

“…According to them, there might have been a mechanism of adjustment to the higher salt intake by the animals. Benatti et al (2012) also observed that supplementation at a lower frequency resulted in a longer time expended on water consumption as compared with daily supplementation. The longer time expended drinking water may be a consequence of the higher amount of DM from supplement consumed per supplementation event.…”

The objective of this study was to evaluate the effects of frequency of concentrate supplementation on the daytime feeding behavior (grazing, rumination, drinking, and idle times), production performance, and economic viability of grazing cattle in the rainy season. A total of 120 uncastrated Nellore animals with an average body weight (BW) of 382.5 ± 32.2 kg were allocated to palisadegrass (Brachiaria brizantha) paddocks for the experiment. We evaluated supplements provided in the amount of 2.0 kg/ animal, supplied three times weekly (3tw) or daily (7X). Animals supplemented 3X (5.46%) spent more time (%) drinking water than those supplemented 7X (3.72%). Grazing time and animal performance were not influenced by the frequency of supplementation. Average daily gain was 1.00 and 1.02 kg/ animal for the groups under 3X and 7X, respectively. Expenditures on transportation and labor are lower (43%) when animals are supplemented 3X. Supplementation provided three times per week does not affect the grazing time or the performance of beef cattle in the rainy season, but rather implies an expressive reduction of expenditures on labor and distribution of supplements. Key words: Performance. Grazing time. Economic viability. ResumoObjetivou-se avaliar os efeitos da frequência de suplementação concentrada sobre o comportamento ingestivo diurno (tempos de pastejo, de ruminação, de bebedouro e de ócio), o desempenho produtivo e a viabilidade econômica de bovinos de corte em pastejo no período das águas. Foram utilizados 120 animais da raça Nelore não-castrados com peso corporal (PC) médio de 382,5 ± 32,2 kg alocados em piquetes formados com capim Marandu (Brachiaria brizantha). Avaliaram-se suplementos ofertados em quantidade de 2,0 kg/animal distribuídos três vezes por semana (3X) e diariamente (7X). O tempo gasto (%) no consumo de água foi maior para os animais que receberam suplementação 3X (5,46%) do que os animais que receberam suplementação 7X (3,72%). O tempo gasto com pastejo e desempenho dos animais não sofreram influência da frequência de oferta do suplemento. O ganho médio diário foi 1,00 e 1,02 kg/animal, respectivamente, para a suplementação 3X e 7X. Os gastos com transporte e mão-de-obra são menores (43%) quando suplementos são ofertados 3X. O fornecimento de suplementos três vezes por semana não afeta o tempo de pastejo e o desempenho de bovinos de corte no período das águas e implica em expressiva redução nos custos com a mão-de-obra e com a distribuição de suplementos. Palavras-chave: Desempenho. Tempo de pastejo. Viabilidade econômica.

Economic efficiency of Rhipicephalus microplus control and effect on beef cattle performance in the Brazilian Cerrado

The cattle tick Rhipicephalus microplus causes significant economic losses to cattle production systems and is a main barrier to the introduction of Bos taurus breeds and their crosses in Brazil. These breeds have the genetic potential to generate animals that are more productive, but they are also more susceptible to R. microplus. One of the alternatives for conventional tick control is the use of strategic control, aiming at delaying or even preventing the development of its resistance to acaricides. The present study aimed to evaluate the economic losses caused by tick infestation on the productive performance of two breeds of beef cattle and to evaluate the economic efficiency of tick strategic control and its impacts on beef cattle production systems. Animal weights were obtained from the literature and were used to calculate the weight loss in kilograms (kg) and the economic loss (US$) caused by R. microplus infestation. The cost/loss ratio of performing strategic control was also calculated. The data show that tick infestation causes economic losses to the breeds and groups of animals evaluated and reduces animal performance (weight loss). The results show a loss of US$34.61/animal in the backgrounding phase and US$7.97/animal in the finishing phase for Brangus animals and its crosses. In conclusion, the data show that strategic control is economically efficient for Brangus animals in the backgrounding phase, independent of the methods used for acaricide application.
