Viability of Brazilian distillers dried grains with solubles for pigs

Abstract

The purpose of this study was to evaluate the performance, carcass, meat and economic viability characteristics of pigs fed Brazilian coproducts of corn ethanol production. A total of 40 finishing pigs were subjected to four levels of distillers dried grains with solubles (DDGS; 0, 100, 200, or 300 g kg-1) for 28 days, and body weight, daily feed intake, daily weight gain and feed conversion were measured. After slaughter, the carcass yield, fat thickness, loin eye area, the depth and perimeter of the loin eye, and the pH and temperature at 45 min and 24 h post-mortem, along with the drip loss and color of the Longissimus lumborum were evaluated. The economic viability of the diets was calculated. The inclusion of DDGS showed a quadratic effect on daily feed intake over 0-14 days. Pigs fed with 300 g kg-1 of DDGS showed worse feed conversion than those fed the control diet over 0-7, 0-14 and 0-21 days. The a* color parameter of the meat decreased linearly with increasing DDGS concentration but the other carcass and meat characteristics were not affected. Inclusion of 184.1 g kg-1 of DDGS showed the best economic viability, considering the cost of weight gain. DDGS may be included in pig diets up to 200 g kg-1 without affecting the performance or carcass and meat characteristics, while 300 g kg-1 compromises feed conversion.

Digestibility, performance and economic efficiency of diets containing phytase and distillers dried grains with solubles for growing pigs

“…Studying 65-85 kg pigs,Corassa et al (2021) showed that inclusion up to 200 g kg -1 DDGS did not affect performance and carcass, suggesting that heavier pigs better support diets with DDGS when compared to the results of the present study. The reduction of performance based on the fiber content present in the DDGS is, according toBurrough et al (2015), due to increases in the insoluble fiber content, with the potential to affect the bacterial population in the colon.The costs of each kilogram of feed were RD R$ 0.4724 kg -1 feed; RD + PHY R$ 0.4811 kg -1 feed; DDGS R$ 0.4305 kg -1 feed; and DDGS + PHY R$ 0.4393 kg -1 feed (exp.…”

“…Thus, it is necessary to know the availability of nutrients and energy of these coproducts for a more precise formulation (Adeola & Kong, 2014), as they characterize the effects on animal performance and economic viability. Meanwhile, there is very little information about the nutritional value of DDGS produced in Brazil (Corassa et al, 2017(Corassa et al, , 2021. The presence of phytic acid in cereal products has limited the use of all nutrients by animals.…”

“…The economic results showed that although the inclusion of DDGS negatively altered the performance, there was no economic damage. It works as a kind of compensation, since the reduction in weight gain is mitigated by the lower cost of the coproduct.Likewise, De Jong et al (2012) concluded that the CWG of pigs fed DDGS was similar to that of the control group, while the economic analysis ofCorassa et al (2021) resulted in 184.1 g kg -1 DDGS as the optimal inclusion. Globally, DDGS attracts pig farms due to its relatively low price, undervalued accordingBuenavista et al (2021) considering the actual economic value in animal diets due to its nutritional content.…”

Variabilidade da composição nutricional de coprodutos de etanol de milho do Brasil para suínos

“…Com enorme potencial de substituição aos ingredientes tradicionais, os coprodutos de etanol de milho podem reduzir custos e otimizar formulações de rações para cadeias produtivas como a suinocultura brasileira, a quinta maior do mundo (ABPA, 2019) entretanto, pouquíssimos estudos com coprodutos do Brasil foram realizados (Corassa et al, 2017(Corassa et al, , 2019(Corassa et al, , 2021.…”
