“…This fact highlights the economic unfeasibility of adding SFO to the experimental diets (Table 6). Similar results have been obtained by Lopes et al (2012), who analyzed the economic feasibility of adding soybean oil to elephant grass-based diets, and Lopes et al (2014), who evaluated SFO supplementation in sugarcane-based diets of lactating cows.…”

“…These findings suggest the importance of formulating low-cost diets, and the need to manipulate certain milk components. Lopes et al (2012) suggested that in addition to the payment policies presently adopted by several dairy companies in relation to somatic cell and total bacterial counts and protein and fat contents, bonuses should also be paid to farmers as an incentive to produce milk with nutraceutical potential that would benefit the health of consumers.…”

We aimed to evaluate the economic feasibility of adding increasing levels of sunflower oil (0.0, 15, 30, and 45 g/kg of dry matter) to elephant grass (Pennisetum purpureum, Schum) based diets of milkproducing Holstein cows. Data were obtained and analyzed for 12 primiparous Holstein cows that produced on average 16.5 ± 2.8 kg of milk/day, at 95 ± 25 days of lactation. Cows were distributed by milk production, order of lactation, and body weight in a 4 × 4 triple Latin square. Isoproteic diets were provided ad libitum in the form of a forage:concentrate ratio of 60:40, on a dry matter basis. Daily milk production was recorded and milk was analyzed for fat, protein, and fatty acids contents. An economic feasibility study was performed considering the price of the supplied ingredients and the daily intake of each diet. The economic benefit was derived by the determining the difference between income from the sale of milk and the cost of animal feed. The quality-based payment was estimated by averaging the systems used by eight dairy companies, based on fat and protein contents and milk volume. The sunflower oil-free diet provided the greatest economic benefit. Adding sunflower oil to elephant grassbased diets was not economically viable because of its associated costs.

ResumoObjetivou-se avaliar a viabilidade econômica da produção de leite de vacas da raça Holandesa, pela inclusão de níveis crescentes de óleo de girassol (0,0; 15; 30 e 45 g/kg na matéria seca) em dietas à base de capim-elefante (Pennisetum purpureum, Schum). Os dados analisados foram obtidos de um experimento com 12 vacas primíparas da raça Holandesa, com 95 ± 25 dias em lactação, produção média de 16,5 ± 2,8 kg/dia de leite, distribuídas em um triplo quadrado latino 4 x 4, conforme a produção de leite, a ordem de lactação e o peso corporal. As dietas foram isoproteicas, fornecidas ad libitum na forma de mistura total (relação volumoso: concentrado de 60:40, base matéria seca). A produção diária de leite foi registrada e a composição analisada quanto à concentração de gordura, proteína e ácidos graxos. A viabilidade econômica foi realizada considerando o preço dos ingredientes fornecidos e o consumo diário da dieta de cada tratamento. O benefício econômico foi obtido pela diferença entre a receita, com a venda do leite, e o custo com alimentação dos animais. O pagamento por qualidade foi estimado pela média de sistemas utilizados por oito empresas do ramo de laticínios, com base na concentração de gordura, proteína e no volume de leite. A dieta sem inclusão de óleo de girassol foi a que proporcionou maior benefício econômico. A inclusão de óleo de girassol nas dietas baseadas em capim-elefante não foi viável economicamente, devido aos gastos com este ingrediente.

“…The economic evaluation was calculated by the methodology of Economic Benefit, proposed by Lopes et al (2012), and also used by Lopes et al (2014) and Lage et al (2016). Estimated by the difference between the revenue obtained from the arrobas (@) produced in the period and leasing expenses of pasture (R$25,00/animal/month), consumption of mineral supplements and work labour used in supply.…”

The objective of this study was to evaluate the effect of the frequency of provision of protein energy supplementation on pasture during the dry period of the year on the performance of Nelore steers in rearing phase. FAZU teaching school conducted the experiment from July to September 2017. Twenty-two animals of the Nelore breed, aged 12 months and mean initial weight of 232.22 (± 20) kg, modules of 2 ha each, subdivided in six paddocks of Panicum maximum cultivars Mombaça and Tanzânia. The experimental design was completely randomized (DIC) and the averages were compared by the Tukey test at 5% significance. There was no significant difference between the three frequencies of supply of energy protein supplementation, in relation to the average daily weight gain, which were 837; 881 and 855g, at the frequencies of 7; 5 and 3 times per week, respectively. However, there was a significant difference (P <0.05) for the mean daily weight gain between the treatment in which the animals received mineral supplementation (434g), which was lower than the treatments in which the animals were fed with protein energy supplement at the level of 0.25% of body weight. In conclusion, during the period and in the evaluation conditions of this experiment, there was no difference in the effect of the frequency of supply of a protein energy supplement in the supply level of 0.25% of the animals' body weight. The average daily gain was higher for the animals that received the protein energy supplement compared to those supplemented with mineral. Five times a week supplementation obtained the best economic benefit among the evaluated frequencies.

RESUMO Objetivou-se, com este estudo, verificar a influência da suplementação com diferentes associações entre minerais orgânicos sobre o desempenho e as características de carcaça, bem como avaliar sua viabilidade econômica, para suínos em terminação. Foram utilizados 88 machos castrados, divididos entre quatro tratamentos: controle com dieta basal e suplementação com CrFe, MgSe e CrFeMgSe, durante os 28 dias que antecederam o abate. O delineamento experimental foi em blocos ao acaso, com parcela experimental representada por dois animais. Os animais suplementados com CrFeMgSe apresentaram piores índices de peso final, ganho de peso diário e consumo durante todo o período, com consequente redução no peso de carcaça, menor profundidade de lombo, área de olho-de-lombo e menor quantidade de carne magra na carcaça. Houve um aumento no custo da dieta para os grupos CrFe, MgSe e CrFeMgSe, respectivamente. O uso de cromo mais ferro e magnésio mais selênio, associados dois a dois, não altera os parâmetros de desempenho e as características de carcaça. A associação dos quatro minerais, no entanto, promove piora nessas características e aumenta o custo da dieta.
