Nutritive value of Saanen goat diets with dried distillers grains with solubles as a replacement for soybean meal

Abstract

The objective with this study was to evaluate the effect of including dried distillers grains with solubles (DDGS) as a replacement for soybean meal on feed intake, digestibility, and total digestible nutrients (TDN), as well as plasmatic glucose and serum urea concentrations. Fifteen Saanen goats were distributed in a completely randomized design with three treatments and five replicates. Treatments were soybean meal (SBM), SBM+DDGS (12.28% of dry matter [DM]), and DDGS (23.16% of DM), as protein source in diets, common to all corn ground and mineral-vitamin supplement, and corn silage (60% of DM). Response variables were evaluated every 30 d, from 1 to 120 d after parturition. Measurements included body weight, DM intake, DM and nutrient digestibility, and blood samples. Indigestible neutral detergent fiber was used to estimate fecal excretion. There was a difference in neutral detergent fiber intake from 1 to 30 d after parturition. In the four phases of lactation evaluated, there were treatment effects on DM, organic matter, ether extract, and total carbohydrate digestibility, as well as on TDN concentration. Neutral detergent fiber digestibility was affected by treatments, except from d 61 to 90. There was no treatment effect on non-fibrous carbohydrate digestibility, regardless of period. Therefore, SBM+DDGS (12.28% of DM), as protein source on diets may be used in Saanen goat diets from 1 to 120 d of lactation without negative effects on feed intake, digestibility, and plasma glucose and urea concentrations.

Moringa oleifera leaf for replacing protein portion of soybean meal in the diet of young growing meat goats

“…Replacing soybean meal with cotton seed cake did not affect intake (de Asis et al, 2018). Replacing soybean meal with dried distiller grain with soluble did not affect intake (Pontes, 2020). Rahman et al (2020) reported a decrease in intake as a result of replacing soybean meal with soy waste.…”

“…Supplementation of M. oleifera extract enhances nutrient utilization in lactating goats and increases blood glucose concentration, and decreases blood trglycerides and cholesterol concentrations (Kholif et al, 2018). Subtitution of soybean meal with dried distiller grain with soluble unaffects feed intake in lactating goats, and blood glucose and urea concentratios remains unchanged (Pontes et al, 2020). Chanjula et al (2022) reported that dietary intake in lactating goats is not affected by replacing soybean meal with fermented palm kernel cake, and blood glucose and urea are also unaffected.…”

“…De Asis et al (2018) reported that nutrient utilization and growth performance in goat kids is not altered when soybean meal portion in diet is replaced with cotton seed flake. Soybean meal portion could be replaced with dried distiller grains in the ration of lactating goats throughout the first four month lactation period, because feed intake and digestibility and some blood metabolites are unchanged (Pontes et al, 2020). Soya waste could be total substitute for soybean meal in the ration of goat kids, because it does not affect feed intake and digestibility, and productive performance (Rahman et al, 2020).…”

“…For ruminants, the inclusion of this ingredient can result in higher dietary cost. Therefore, the use of other protein sources instead of soybean meal may be a strategy to reduce production costs of dairy farming, not compromising its performance (Naves et al, 2015;Pontes et al, 2020).…”
