“…The higher degradability of DM causes privileged rumen metabolism. The IVD and IVOMD of rice straw without any supplement were very low due to various lignocellulosic bonds (Mahfuz et al., ). On the other hand, the IVD and IVOMD of rice straw were higher in presence of black cumin, cumin and turmeric.…”

“…Concentrate mixtures contained wheat bran (200 g/kg DM), maize (180 g/kg DM), groundnut cake (145 g/kg DM), mustard cake (130 g/kg DM), barley (145 g/kg DM), rice polishing (110 g/kg DM), soybean meal (60 g/kg DM), mixed minerals (20 g/kg DM), common salt (10 g/kg DM). The rumen fluid was strained through double layers of muslin cloth into preheated thermos under anaerobic condition before mixing with phosphate‐bicarbonate buffer (Mahfuz et al., ) at 1:3 ratio to prepare the inoculum. The flasks were then screw capped and kept at 39°C in a water bath until used.…”

“…To get optimum production and reducing the NH 3 ‐N loss from ruminants, it is necessary to increase the utilization of low‐quality forages (LQFs) and nitrogen (N). In developing countries, rice straw is available and commonly used as basal feed for large ruminants (Mahfuz, Chowdhury, Baset, & Khan, ). Feeding ruminants with only rice straw is a common practice in many areas.…”

The objective of the study was to evaluate the effects of spices on forage utilization and nitrogen (N) emission using in vitro and in vivo approach. A 6 × 5 factorial triplicate arrangement was used to assess the in vitro degradability of rice straw with control (without spices) and individual (40 mg/g rice straw) spices (cumin, coriander, clove, black cumin, turmeric) at five different incubation times. In vitro dry matter (DM) and organic matter (OM) degradability of rice straw were highest in presence of spices except for clove. Clove significantly reduced the total volatile fatty acids concentration, molar proportion of acetate and propionate ratio, but increased propionate production. Acetate and butyrate production were not affected by treatments. The ammonia-nitrogen concentration was lowest for clove and turmeric compared to other spices. Rumen pH was unchanged but gradually decreased over the incubation period. For in vivo study, 12 bucks with average live weight 7.65 ± 0.19 kg were assigned to a completely randomized design with three treatments and four replicates for a 28-day period. Bucks were fed a total mixed ration without (0 g/kg DM) or with (2.5, 7.5 g/kg DM) clove supplementation. DM intake, body weight and apparent total tract digestibility of crude protein (CP) and acid detergent fibre (ADF) were not affected by increasing dietary doses of clove but tended (p = .09) to increase DM and OM digestibility. The urinary N and urine urea N concentration of bucks decreased linearly with incremental doses of clove diet. In contrary, clove supplementation had positive effects on plasma urea N and retained N in bucks. We concluded that though some spices had positive effects on ruminal digestion and fermentation, the dosage level assessed in the current study (up to 7.5 g/kg DM clove) can be promoted as an effective dietary approach to mitigate N losses in bucks.

“…In vitro degradability values of solid herbal waste in this study are equivalent to the degradability of rice straw but higher than pod husk cacao. According to Mahfuz et al (2014), the value of dry matter and organic matter degradability of rice straw with 0-12 g/kg phosphorous supplementations at 48 h was between 28.75%-56.25% and 35.77%-59.21% repectively, while dry matter degradability of fermented pod husk was between 21.75%-25.78% (Nelson, 2011), meanwhile in vitro digestibility of pod husks between 33.78% to 39.10% (Islamiyati, 2010).…”

The aims of this research were to study the nutrient and secondary metabolite contents of solid herbal wastes (SHW) that were preserved by freeze drying, sun drying and silage, as well as to analyze their effects on in vitro fermentation indicators i.e., gas production kinetics and degradability of solid herbal waste. Physical and chemical properties on three forms of SHW (sun dry, freeze dry, and silage) were characterized and then an in vitro gas production experiment was performed to determine the kinetics of gas production, methane production, NH 3 , microbial protein, and SHW degradability. Polyethylene glycol (PEG) was added to the three treatments to determine the biological activity of tannins. Results showed that all three preparations of SHW still contained high nutrient and plant secondary metabolite contents. Gas production, methane, NH 3 , microbial protein, in vitro degradability of dry matter (IVDMD) and organic matter (IVDOM) of SHW silage were lower (P<0.05) compared to sun dry and freeze dry. These results were apparently due to the high content of secondary metabolites especially tannin. It can be concluded that solid herbal wastes (SHW) can be used as an alternative feed ingredients for ruminants with attention to the content of secondary metabolites that can affect the process of fermentation and digestibility in the rumen.Keywords: solid herbal waste, plant secondary metabolites, antimicrobial effect, in vitro rumen fermentation ABSTRAKPenelitian ini bertujuan untuk mengevaluasi efek limbah padat jamu (LPJ) yang mengandung berbagai metabolit sekunder tanaman pada kinetika produksi gas, indikator fermentasi, dan kecernaan dalam rumen pada kondisi in vitro. Pada tahap pertama penelitian dilakukan analisis fisik dan kimia pada tiga sediaan LPJ (kering matahari, freeze dry, dan silase), selanjutnya dilakukan percobaan in vitro produksi gas untuk mengetahui kinetika produksi gas, produksi metan, NH 3 , protein mikrobia, dan tingkat degradasi LPJ secara in vitro. Polyethylene glycol (PEG) ditambahkan pada ketiga perlakuan untuk mempelajari aktivitas biologis tanin. Hasil penelitian menunjukkan ketiga sediaan LPJ masih mengandung nutrien dan metabolit sekunder tanaman yang relatif tinggi. Produksi gas, metan, NH 3 , protein mikrob, dan degradasi in vitro bahan kering dan bahan organik silase LPJ lebih rendah (P<0.05) dibandingkan LPJ kering matahari dan freeze dry yang diduga disebabkan oleh kandungan metabolit sekunder, terutama tanin yang tinggi. Melihat potensi kandungan nutriennya, dapat disimpulkan bahwa limbah padat jamu (LPJ) dapat digunakan sebagai alternatif bahan pakan pengganti serat dengan perhatian pada kandungan metabolit sekunder yang dapat mempengaruhi proses fermentasi dan kecernaan di dalam rumen.Kata kunci: limbah padat jamu, metabolit sekunder tanaman, efek antimikrob, fermentasi rumen in vitro

“…Thus, the evaluation of these sources should be carried out in the long term and to supplement soil P availability during successive crop cycles and in large-scale plant experiments. As shown by Mahfuz et al, soluble sources as TSP can better supply the high demand of P by plants, especially in the initial phase of growth, when compared to rock phosphates. In addition to that, a linear analysis between the treatments can be done once the powder application is an ideal scenario for nutrient applications.…”

Food security is one of the biggest challenges for the next few decades, especially with the accelerated population growth rates. Therefore, achieving a better nutrient use efficiency is crucial to enhance crop yields and productivity, which depend directly on how macronutrients are supplied. It is notably complex because fertilizers are often applied as granules instead of more soluble powdered forms. Here, we propose a new model for an allin-one NPK fertilizer production, which allows quickly adjustable compositions in multi-nutrient granules. Thus, thermoplastic starch has been used as a biodegradable matrix binder mixed with the fertilizers in a continuous process by extrusion. Urea and KCl were considered as N and K sources, respectively. P sources with different solubilities (triple superphosphate (TSP) and Bayovar and Patos phosphate rocks) have been tested and compared. The greenhouse experiment revealed that the TSP composite promoted superior biomass production than the standard application, in addition to an overall better nutrient uptake. While Bayovar did not benefit from the all-in-one granule, Patos results were improved in this system, revealing a boost in its solubilization.
