The Influence of Distillers Dried Grains with Solubles During Gestation on Sow Productivity and Milk Composition

Abstract

This study aimed to evaluate the effects of distillers dried grains with solubles (DDGS) during gestation on sow productivity, litter performance and milk composition. Thirty-six second-and third-parity (2.27 parity) sows (Yorkshire) were bred with semen from a pool of Landrace boars. The sows were randomly allotted to 1 of 3 groups and fed diets containing 0 (control), 12.5 or 25% DDGS during gestation. The sows were divided into 12 blocks of three animals. Piglets were cross-fostered, within dietary treatment groups 48 h after birth to standardise litter size to a range of 9 to13 piglets. The 25% DDGS supplementation resulted in a greater (P=0.03) average daily feed intake (ADFI) during lactation compared with control sows. The weaning-to-oestrus interval was shorter in sows receiving 25% DDGS diets compared to the control (P=0.01). The number of piglets born was similar among treatments. The addition of 12.5 and 25% DDGS to the gestation diet increased the average daily gain (ADG) of the piglets during lactation (P=0.04). The results demonstrated that feeding 25% DDGS does not have negative effects on sow or litter performance and increases the sow ADFI and the piglet ADG during lactation.

Effects of soybean hulls and corn stalk on the performance, colostrum composition and faecal microflora of pregnant sows

“…Studies have shown that fibre nutrition regulation of sow milk composition have yielded inconsistent results. Shi et al (2014) showed that high‐fibre diets during pregnancy had no significant effects on protein, fat and lactose in the colostrum and milk of pigs. This is consistent with the results of this study.…”

By-product Originating from Artisan Distillers of Rice Alcohol in Northern Vietnam: Production, Use and Nutrient Value for Smallholder Pig Raising

“…This result is consistent with previous report [2] who indicated that litter size and piglet weight at birth were reduced by about 5 and 20% in gestative sows fed diet containing 33% DM RDP in comparison with that deprived of. However, according to [23,24] no effect was observed up to 30% DM RDP in diet. Even more, increased average daily feed intake as well as average daily gain of piglets was observed during lactation [23].…”

“…However, according to [23,24] no effect was observed up to 30% DM RDP in diet. Even more, increased average daily feed intake as well as average daily gain of piglets was observed during lactation [23]. Feeding as high levels of DDGS as 40 to 50% could be reduced sow feed intake and litter performance [24].…”

Desempenho produtivo e reprodutivo de Lambaris-de-rabo-amarelo (<i>Astyanax altiparanae</i>) alimentados com dietas contendo diferentes níveis de grãos secos de destilaria com solúveis (DDGS)

“…Rodrigues et al (1992), concluíram em suas pesquisas que o fator de condição corporal do Astyanax altiparanae diminuiu quando os índices gonadossomáticos atingiram o seu máximo pico de desenvolvimento. Ocorrência que não foi visualizada neste trabalho porque a coleta das gônadas foi feita em um único período.Trabalhos que relacionam a inclusão do DDGS nas dietas para reprodutores de peixes são escassos, porém em monogástricos tais como os suínos, reporta-se a inclusão de 50% de DDGS nas dietas para fêmeas em gestação e 20% para fêmeas em lactação(STEIN, 2007) Shi et al (2014). apontaram o uso de 12,5 a 25% de DDGS em substituição parcial e total da farinha de soja nas dietas para porcas gestantes e lactantes, e constataram que a inclusão de DDGS não afetou negativamente no desempenho das porcas e na composição do leite, ademais o consumo diário médio da ração e o ganho de peso médio dos leitões aumentou.…”
