“…In Australia, high-cost supplements are often uneconomic and unless they are required within the growth path to a profitable end point, are best not used except for minimal low-cost supplements such as urea. In Brazil, where supplements are much cheaper and a wider range is available, the result appears be very different (Dórea, 2010;Detmann et al, 2014;Barbero et al, 2015;De Oliveira et al, 2016).…”

“…There has been a collation of data from Brazil (Dórea, 2010;Detmann et al, 2014;Barbero et al, 2015;De Oliveira et al, 2016) and these generally outline the same features: CP ranged from 3.4-21.0% and live weight gain ranged from −0.36-1.2 kg/day. Data from Brazil more closely aligned with that from the endowed zone of Queensland and not as harsh or challenging as that from the dry tropics of Australia.…”

“…McLennan (1997) defined the response to supplement type by season in northern Australia, Poppi et al (1997) collated responses to supplements for basal forages of high and low quality, and Dórea (2010), Detmann et al (2014), Barbero et al (2015), and De Oliveira et al (2016) collated or developed response curves over the wet and dry seasons of Brazil (Figure 5). …”

-The live weight gain of cattle on tropical pastures is reviewed and found to be low and dependent on the length of the growing season. Supplements may be added to address the primary limiting nutrient, which, in the dry season, is crude protein. The response relationships of live weight gain to level of supplement (protein or energy) that have been developed for animals on pasture in Brazil and Australia have been compared and found to be very similar. This gives confidence in recommending a supplementation strategy for cattle on tropical pastures. Response in the wet season was very low and likely to be uneconomic compared with dry season supplementation. Supplementation is costly and should only be used as a last resort, but the strategy needs to be viewed in the context of a growth path to a defined market or slaughter weight. In Australia, high inputs in the first dry season are risky as subsequent compensatory growth can reduce or eliminate the weight advantage of a supplement. There is less financial risk in using supplements towards the end of the growth path. Growth paths can follow many forms and there is no need to maximise live weight gain in each period. Targeted supplements in the second dry season, leucaena based systems, other special-purpose pastures or crops, and feedlots offer the most economical way for cattle to meet market targets. The expected annual live weight gain and weaning weight are other major factors which determine the growth path, target market which can be achieved, and the level of intervention (supplements, legumes, feedlots, etc) which are required and when. Some recent results on growth paths in Australia are presented.

“…Therefore, considering that the main objective of supplementation is to maximize the use of available forage, we found that concentrate supplementation at levels close to 0.2% BW provides an increase in total DM intake without reducing pasture intake. In addition, there is a consensus in the literature that supplementation up to this level is not substitutive, but rather associative, or has combination effects (OLIVEIRA et al, 2015).…”

An experiment was carried out to investigate the effects of supplementation strategies on intake, digestibility, and performance of Nellore cattle on pasture (Urochloa decumbens) during the rainy-dry transition period. The evaluated strategies were mineral supplementation (MS), self-feed supplementation (SF), and infrequent concentrate supplementation. Supplementation frequencies were three times per week (Mondays, Wednesdays, and Fridays -3tw) and daily (7tw). Animals receiving concentrate supplementation had higher pasture DM and TDN intakes than those fed MS. There was no difference (P > 0.10) between concentrate supplementation strategies. Average pasture DM intake was 7.89, 8.09, and 8.10 kg day −1 for SF, 3tw, and 7tw, respectively. No effects were found (P > 0.10) between SF and infrequent supplementation, or for the supplementation frequencies tested. The lowest average daily gain (ADG) (P < 0.10) was found for animals fed MS, and there was no difference between concentrate supplementation strategies for this variable. Average daily gains for MS, SC, 3tw, and 7tw were 661.4, 812.7, 811.5 and 819.2 g/animal, respectively. During the rainy-dry transition period, grazing beef cattle receiving concentrate supplementation have higher pasture and TDN intakes and better performance than animals fed mineral supplement only. Self-feed supplementation or supplementation provided three days per week do not compromise pasture and TDN intakes, nutrient digestibility, or performance of grazing beef cattle. Key words: Digestibility. Infrequent supplementation. Intake. Performance. Self-feed supplementation. ResumoUm experimento foi conduzido para estudar diferentes estratégias de suplementação sobre o consumo, a digestibilidade e desempenho de bovinos Nelore a pasto (Urochloa decumbens) durante o período de transição águas-seca. As estratégias avaliadas foram: suplementação mineral (SM), a suplementação tipo autocontrole de consumo (AC) e suplementação infrequente. As frequências de suplementação avaliadas foram a três vezes/semana (segundas, quartas e sextas-feiras -3X) e diariamente (7X). Os animais que receberam suplementação de concentrado apresentaram maior consumo de MS de pasto e NDT do que aqueles que receberam SM. Não houve diferença (P > 0,10) entre as estratégias de suplementação concentrada com média de ingestão de MS de 7,89; 8,09 para AC, 3X e 7X. Nenhum efeito foi encontrado (P > 0,10) entre suplementação AC e as frequências estudadas que não diferiram entre si. Verificou-se menor ganho médio diário (GMD) (P < 0,10) para os animais alimentados com SM e não houve diferença entre as estratégias de suplementação concentrada. Os GMD foram de 661,4; 812,7; 811,5 e 819,2 g/animal, respectivamente para SM, AC, 3X e 7X. Durante a época de transição águas-seca, bovinos de corte que recebem suplementação concentrada apresentam maiores consumos de MS de pasto e de NDT e desempenho do que animais alimentados apenas com suplemento mineral. Suplementos tipo AC ou suplementos ofertados 3X/semana não impacta n...

“…For PS and PES supplements, this corresponds to costs of 1.47 and 2.98 US$ per kg of extra gain above that observed on non-supplemented steers (Table 3). The use of protein-energy supplement in the post-weaning phase increases the production costs, but it may be advantageous to reduce the age at slaughter or aging at first calf (Oliveira et al, 2015). Thus, an effective strategic supplementation program must implement the most effective and lowest cost nutritional intervention to achieve production goals.…”

The objectives were to: 1) evaluate the potential of the animal performance on Panicum maximum cv. Mombaça (mombaça guinea grass) pasture during dry season, and 2) determine the effects of protein or protein-energy supplementation on liveweight gain of steers grazing guinea grass pasture. A complete randomized block design was employed with three treatments and three replicates. Treatments included non-supplemented animals (NS) and animals supplemented with protein (PS) or protein-energy (PES), provided at 0.15% or 0.6% of body weight for 115 days, during dry period. We used 36 weaned calves from initial bodyweigh (LW) of 192 kg (±5 kg) on nine plots of mombaça guinea grass (1.25 ha each). Each month, animals were weighed and pastures sampled to estimate forage characteristics. The average daily gain (ADG) was greater (P = 0.0001) for cattle fed supplement than for cattle fed no supplement (250 g steer ). Mombaça guinea grass pastures with 45 cm height at the end of the wet season have enough forage mass for maintenance throughout the dry season about 1.4 AU ha -1 (AU = 450 kg BW), and reasonable nutritive value (average of 8,1% of crude protein and 55,3% of in vitro organic matter digestibility) to provide small gains. Considering the nutritive value of Mombaça guinea grass during the dry period, protein and energy supplementation is required for weaned calves to optimize their performance.
