Blood Metabolites and Feed Utilization Efficiency in Thai-Native-Anglo-Nubian Goats Fed a Concentrate Diet Including Yeast Fermented Palm Kernel Cake Instead of Soybean Meal

Abstract

Feed is the most expensive component in goat production. Hence, lowering it is crucial to increasing producer profitability. The microbial community in rumen is vital for nutritional digestion and absorption in ruminants. Live yeast and yeast-based products generated from the strain Saccharomyces cerevisiae (commercial strain) are actively being used and investigated. The purpose of this study was to investigate the effects of substituting soybean meal (SBM) in concentrate diets with yeast-fermented palm kernel cake protein (YFPKCP) on dry matter intake, digestibility, blood markers, and nitrogen balance. Five crossbred Thai Native-Anglo-Nubian goats (50% Thai Native goats with 50% Anglo-Nubian goats) weighing an average of 27 ± 2 kg were randomly allocated to one of five diets using a 5 × 5 Latin square design: 0, 25, 50, 75, and 100% YFPKCP replacement for SBM. Plicatulum hay (Paspalum plicatulum Michx.) was provided ad libitum. There were no significant differences in dry matter (DM) intake among treatments, but the apparent digestibility of DM, crude protein (CP), neutral detergent fiber (NDF), and acid detergent fiber (ADF) were affected (p < 0.05) by including YFPKCP in diets. They also tended to be slightly lower for goats fed the diet containing 100% YFPKCP replacement for SBM compared to other treatments. Ruminal pH, ammonia-nitrogen (NH3-N), blood glucose, and packed cell volume were equivalent among treatments. On the other hand, replacement YFPKCP reduced digestibility and N absorption by up to 75% (p < 0.05). Furthermore, there was no difference in total volatile fatty-acid concentration among goats fed YFPKCP as a substitute for SBM. According to the results of this study, the level of YFPKCP in the concentrate replacement of SBM for goats fed plicatulum hay should be 75%.

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

“…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.…”

Potential Utilization of Oil Palm Plantation Waste Supports Beef Cattle Development in West Sulawesi

“…OPM can be processed using silage technology to meet the needs of animal feed, while cow dung can be used as biogas so that people can get economic benefits [27]. Palm kernel cake fermented with yeast has nutritional content, namely DM 88.61%, CP 41.67%, NDF 47.98%, ADF 32.50%, OM 96.12% [28]. Meanwhile, palm kernel cake fermented using a combination of two cellulolytic and hemicellulolytic bacterial cultures reduced the cellulose, hemicellulose, ADF, and NDF to increase digestibility and suitable for use as feed ingredients in monogastric without disturbing growth.…”
