Abstract

Oil Palm fronds (OPF) as the main waste of oil palm plantations have considerable promise as a small ruminant feed. Unfortunately, due to the diversity of previous findings, a clear response pattern has still to be determined. For this reason, in the present study, meta-analysis was employed to synthesize existing findings regarding the effect of OPF as a small ruminant feed. The database was constructed using data from ten published articles that fit the inclusion criteria. The applied statistical model was a mixed model. Findings revealed no significant effect (P>0.05) of OPF inclusion on nutrient intake, nutrient digestibility, animal performance, and nitrogen utilization. Despite this, there was a tendency for dry matter intake (DMI) to increase and average daily gain (ADG) to decrease with the greater presence of OPF in the feed. The insignificance of the present findings suggests that OPF can be included in small ruminant feed without causing significant negative effects.

Abstract

Diets formulated for laying hens often contain anti-nutritional factors—such as non-starch polysaccharides (NSPs), trypsin inhibitors, and phytate—that can impede nutrient absorption. To mitigate these effects and enhance feed efficiency, the poultry industry increasingly incorporates exogenous enzymes like xylanase and protease, either separately or synergistically, to improve the digestibility and nutritional value of by-product feed ingredients. This study was conducted to evaluate the effects of xylanase and/or protease enzyme supplementation in laying hen diets on nutrient digestibility and overall bird performance. Four distinct dietary treatments were formulated, including a negative control (NC) diet that did not contain any enzyme supplementation. The remaining three dietary treatments were modifications of the negative control (NC) diet, incorporating either xylanase, protease, or a combination of both enzymes (xylanase + protease). The NC diet was formulated to contain 2,567 kcal/kg of apparent metabolizable energy corrected for nitrogen (AMEn), 0.77% digestible lysine (dLys), and phytase supplementation. Performance trial showed that supplementation of protease and xylanase+protease had higher (p<0.05) hen day production (HDP) compared to NC (88.29 and 88.69% vs 83.53%, respectively). AMEn determination study showed that only xylanase improved (p<0.05) AMEn, compared to NC (2,754 vs 2,585) kcal/kg. Amino acid digestibility (dAA) study showed that xylanase and xylanase+protease improved (p<0.05) dLys by 0.04% and 0.07% respectively. In summary, supplementation of xylanase and protease enhances nutrient utilization and production performance in laying hens fed high by-product diets. The combined use of both enzymes showed the greatest benefits, suggesting that multi-enzyme strategies may be more effective than single-enzyme approaches. These results support the use of enzyme supplementation to enhance feed efficiency and sustainability in poultry production.

Abstract

The effect of using saponins on ruminants' performance differed from several published research data based on the level of saponins added to the feed. This research was conducted to analyze the effect of saponins on fermentation characteristics, digestibility, and estimation of methane in ruminants with a mixed model approach from published journal articles—a total of 127 studies from 32 journals national and international. The variable measured included the level of saponins (%), dry matter intake, Average Daily Gain (ADG), Dry Matter Digestibility (DMD), Organic Matter Digestibility (OMD), Crude protein (CP), Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), protozoa population, bacterial population, Volatile Fatty Acid (VFA), acetate/C2, propionate/C3, butyrate/C4, valerate/C5, acetate/propionate (C2/C3), NH3, pH, and methane gas production. The results showed that using saponins in ruminants increased ADG, CP, ADF, NDF degradation, Total VFA, and proportion of propionate. The addition of saponins level reduced the protozoa population, acetate proportion, and the ratio of acetate: to propionate (C2/C3). In contrast, feed intake and digestibility decreased with the administration of saponin. The bacterial population were similar among treatments, and methane production increased by increasing saponins. In conclusion, the administration of saponin level recommended is 0.3-3.1% of the total ration to improve performance and increase feed efficiency.

Abstract

Herbal plants in animal feed offers a more natural and safer alternative than synthetic antibiotics, which can lead to bacterial resistance and leave residues in poultry products. This meta-analysis study evaluated the potential of Moringa (Moringa oleifera) leaves extract as a feed additive for broiler chickens, comparing two administration methods, inclusion in feed or dilution in drinking water. Data were obtained from 29 relevant articles sourced from Google Scholar and Scopus, resulting in the analysis of 123 studies using SAS software. The results showed that administering Moringa leaves in feed significantly increased final body weight and improved feed conversion ratio (FCR), with an average FCR value of 1.92. No significant effects (P>0.05) on were identified in Moringa-boost drinking water. The average final weight of chickens given Moringa in feed compared to in drinking water was 2.09 kg vs. 2.04 kg. The carcass yield from Moringa extract in feed compared to drinking water was 71.11% vs. 78.35%. Conclusively, solid Moringa leaf extract at a dose of 0.71–1.04% is a more effective feed additive because higher dosages induce anti-nutritional factors like tannins and saponins that reduce performance. This finding offers a valuable reference for farmers to utilize local resources in cost-effective and eco-friendly way to enhance broiler chicken production efficiency.

Abstract

The study aims to analyze the influence of feed given (rice straw) of methane gas generated from the digestion occurs in the rumen, production and quality of milk produced, and the influence of methane gas generated on the production and quality of milk produced. Materials used is 12 tail of dairy cow FH (Friesian Holland) inlactation 2-4 at KUNAK, rice straw and elephant grass feed, concentrates, pulp, animal feces, 500 ml fresh milk samples of each dairy cattle, and others. Variables measured was feed intake and digestibility,production of methane gas, as well as the production and quality of milk. The data was processed with SPSS using random design complete with 3 treatments, each 4 dairy cattle. The results showed that the average feed intake and digestibility was found highest on treatment by rice straw feed, production of methane gas generated is also the highest of 6601.90 KJ/d due to high crude fiber content, but most milk production low at 10.06 l / head / day because it is influenced bymethane gas generated on the production.On average the quality of milk in rice straw feeding treatment was higher than other treatments.
