Effect of Amount and Ruminal Degradability of Soybean Meal Protein on Performance of Lactating Dairy Cows

Context Several agro-industrial by-products such as oil palm meal could be useful as animal feeds in support of low cost of feed for livestock production. Aims This study investigated the effects of oil palm meal and urea pellet (PMUP) as a protein replacement for soybean meal (SBM) on feed intake, nutrient digestibility, rumen fluid characteristics, milk yield and milk composition in lactating dairy cows. Methods Five multiparous, early to mid-lactation, Holstein-Friesian crossbred dairy cows (75% Holstein-Friesian × 25% Thai Native Bos indicus) were randomly allocated in a 5 × 5 Latin square design to receive PMUP replacement for SBM at 0, 25, 50, 75 and 100% in concentrate. Key results The results show that roughage, total dry matter (DM), organic matter (OM) and acid detergent fibre (ADF) intakes in the cows fed with 25–75% PMUP were significantly higher than in the cows fed 100% PMUP (P < 0.05), whereas the ether extract (EE) intake of the cows receiving the PMUP was higher than that of the control (P < 0.05). Accordingly, the apparent digestibility, ruminal ammonia nitrogen (NH3-N) and total volatile fatty acid (VFA) of cows fed with PMUP replacement of SBM at 25–75% was higher than that in cows fed with 100% PMUP. In addition, milk yield and milk composition were not significantly different among treatments, whereas feed costs per kg milk yield was lowest in cow fed with 100% PMUP (P < 0.05). Conclusions Replacing SBM with PMUP up to 50–100% in concentrate could reduce costs of feed per kg milk yield, but lower feed intake, nutrient utilisation and rumen fermentation were observed in cow fed with 100% PMUP. The use of PMUP from 25–75% replacement of SBM had no significant effects on the feed intake, nutrient utilisation, rumen fermentation and milk production. Therefore, the level of PMUP replacement of SBM in concentrate for lactating dairy cow should not exceed 75%. Implications PMUP could be used as a protein replacement for SBM in concentrate for lactating dairy cows. These findings should be applied further in practical farm condition in order to increase livestock production efficiency.

The aim of the present study was to evaluate effects of partial replacement of corn grain and soybean meal with whole raw soybean or whole cottonseed on milk yield and composition, digestibility, ruminal fermentation and blood metabolites. Eighteen multiparous Holstein cows (133.0 ± 53.1 days in milk, 585.2 ± 54.2 kg of BW and 32.22 ± 5.32 kg/day of milk) were used in six 3 × 3 Latin squares with 21-day periods. The cows were randomly assigned to receive one of the following diets: control (CT), diet without oilseed inclusion; whole soybean (WS), inclusion of 120 g/kg of whole raw soybean (diet DM basis); and whole cottonseed (WCS), inclusion of 120 g/kg of whole cottonseed (diet DM basis). Dietary supplementation with WS or WCS had no effect on milk yield and composition. DM and non-fibre carbohydrate intake were decreased in cows fed WS and WCS when compared with CT; however, WS and WCS increased ether extract intake and digestibility. The WCS decreased DM, crude protein, ether extract and non-fibre carbohydrate intake when compared with WS. Cows fed WCS had higher ruminal pH than those fed WS or CT. Cows fed WS showed higher propionate concentration than cows fed WCS. Ruminal ammonia nitrogen concentration decreased when cows were fed WS compared with those fed CT or WCS. The partial replacement of corn grain and soybean meal with WS or WCS in diets of mid-lactating dairy cows decreased DM intake and altered ruminal fermentation, but did not affect milk yield and composition.
