“…The rate of decrease, expressed as percentage/day, was -0.16 and -0.05 for WPC-and TMR-silage, respectively. As previously indicated by Wang et al (2010), this result was most probably due to the enzymatic breakdown of cellulose and hemicelluloses during storage. A treatment x day interaction was also registered for NFC (P = 0.03; table 2).…”

Efecto de ensilar una ración totalmente mezclada sobre la calidad nutricional para el ganado en pequeñas explotaciones lecheras G Bretschneider * , J Mattera, A Cuatrin, D Arias, R WanzenriedInstituto Nacional de Tecnología Agropecuaria, Estación Experimental Agropecuaria Rafaela, Santa Fe, Argentina. RESUMENEl objetivo de este estudio fue determinar el impacto del ensilado sobre la composición química y las características fermentativas y sensoriales de una ración totalmente mezclada (TMR). La planta entera de maíz (WPC) fue ensilada sola, como control, o combinada con otros alimentos disponibles en la región. Los alimentos ensilados se almacenaron en minisilos durante 75 días. No se observó desarrollo de moho. La variable de color se calificó como buena para ambos tratamientos, mientras que el olor se calificó como moderado para el ensilaje de TMR y bueno para el ensilaje de WPC. No hubo diferencias en el patrón y la tasa de disminución del pH entre los tratamientos. Sin embargo, los valores promedios de pH difirieron (P < 0,01; 3.81 vs. 4.38) entre los ensilajes de TMR y de WPC, respectivamente. La concentración de materia seca (MS) (36,58 vs. 64,25 %; P = 0,001), proteína bruta (9,89 vs. 18,15%; P = 0,005) y energía metabolizable (P = 0,03; 2,51 vs. 2,80 Mcal/kg MS) resultó, como era esperado, mayor para el ensilaje de TMR. El contenido de fibra detergente neutro disminuyó durante el almacenamiento, aunque a una velocidad diferente (P = 0,04) para cada tratamiento. Expresada como porcentaje/día, la tasa de disminución fue -0,16 y -0,05 para los ensilajes de WPC y de TMR, respectivamente. Se sugiere que el ensilado de TMR es una tecnología simple y de bajo costo que podría ayudar a mejorar, mediante una mejor alimentación del ganado lechero, los ingresos económicos de los pequeños productores lecheros.Palabras claves: ración totalmente mezclada, ensilaje de maíz, lechería, pequeños productores. SUMMARYThe aim of this study was to assess the impact of ensiling a total mixed ration (TMR) on chemical composition, fermentation and sensory characteristics. Whole-plant corn (WPC) was ensiled alone, as a control, or in combination with other available local feeds. Ensiled feedstuffs were manually mixed and packed into mini-silos. Thereafter, they were stored and allowed to ferment for 75 days. Mould growth was not observed. Color was scored as good for both silage treatments, whereas odor was scored as moderate for TMR silage and good for WPC silage. The pattern and rate of decrease of pH during the storage was not different between silage treatments. However, mean pH values were different (P < 0.01; 3.81 vs. 4.38) between WPC-and TMRsilages, respectively. Relative to WPC silage, the concentration of dry matter (DM) (36.58 vs. 64.25 %; P = 0.001), crude protein (9.89 vs. 18.15 %; P = 0.005) and metabolizable energy (P = 0.03; 2.51 vs. 2.80 Mcal/kg DM) was higher for TMR silage, as expected. Furthermore, the neutral detergent fibre content decreased along the storage but at a different rate (P = 0.04) for each silage...

“…or to construct facilities for TMR feeding. In response to this situation, Chinese researchers proposed to ensile TMR in bales as a suitable alternative to intensify small-scale farms (Wang et al 2010). Furthermore, Japanese (Wang and Nishino, 2008) and Israeli (Weinberg et al 2011) researchers also performed studies on this topic.…”

“…The concept of silage conservation in bales was already in practice in the late 1970s. Thenceforth, the baling technology has been widely used to produce round bale silages, from a large feed factories to small‐scale farms (Wang et al, ). Bales are wrapped in plastic film to ensure proper fermentation in anaerobic conditions without building dedicated structures (Bortolini, Cascini, Gamberi, & Mora, ).…”

The main objective of this article was to mathematically formulate the problem of the uniform coverage of round baled silage, solve this problem and propose a design approach. A mathematical model which describes the distribution and consumption of stretch film used for bale wrapping is derived. The model aims at capturing more features of a realistic description of the wrapping process than existing mathematical models, so as to provide a deeper insight into the issues concerning bale coverage and film consumption. Bale and film dimensions, mechanical properties of the stretch film described by the Poisson ratio and unit deformation, the overlap between adjacent film strips and the pre‐assumed number of basic film layers are taken into account. It is proved that the complete set of the overlap ratios guaranteeing uniform film distribution is composed of irreducible fractions in which dividend is the divisor minus one. For the bale wrapping technique, only the first four equal to 12,23,34,45 are significant. However, the essence of this study is the uniform film distribution, but optimization and robustness issues are also discussed. Simple mathematical rules are derived to calculate the optimal overlap ratios which minimize film usage. The parallelism between the uniform film distribution and minimal film usage is demonstrated, but it is also proved that these requirements are not equivalent. Robustness on the wrapping process disturbances is examined, and two algorithms for robustly optimal overlap ratio design are developed. The main developments are illustrated by examples, figures and supporting discussions.

“…pH decreased in complete feed with ramie waste was linear to the increasing concentration of C 2 , C 3 , C 4 or LA after ensilage. pH decreased during ensilage of the ball-shaped complete feed, but the concentration of C 2 , C 3 , lactic acid and ammonia-N increased (Wang et al, 2010).…”

“…LA concentration in ball-shaped complete feed was 1040 mg/100 g DM, and increased to 3800 g/100 g DM after 30 day ensilage. The pH of ball-shaped complete feed decreased from 5.35 to 4.65, and DM loss was 43 g/kg DM with 40:60 ratio of green feed: concentrate (Wang et al, 2010). Average pH complete feed with ramie waste without ensilage was 5.99±0.36 (CF 0 N) and 6.77±0.55 (CF 0 H), higher than that with ensilage, namely 4.99±0.36 (CF 1 N) and 4.61±0.09 (CF 1 H) (P<0.01).…”

Abstract. The objective of this research was to evaluate the effect of ensilage technology (with and without ensilage) and protein sources (plant and animal) in complete feed with ramie-waste on nutrient composition and ensilage parameter. Ensilage process decreased significantly dry matter (DM), organic matter (OM) and neutral detergent fiber (NDF), but it increased ensilage parameter i.e. acetate acid (C 2 ), propionic acid (C 3 ), butyric acid (C 4 ), lactic acid (LA), and decreased pH. It also had non-significant effect on crude fibre (CP), acid detergent fiber (ADF) and ammonia (NH 3 -N). Animal protein source in silage making decreased nutrient composition i.e. OM and CP and ensilage parameter i.e. C 2 , but it increased NH 3 -N. Interaction between ensilage treatment and protein sources affected CP and pH also ensilage parameter of C 2 and C 3 . In conclusion, plant protein used in silage of complete feed with ramie waste was better than animal protein, despite that both ensilage were not better due to pH over 4.5.Key words: ramie, ensilage technology, protein source, nutrient composition, ensilage parameter Abstrak. Penelitian ini bertujuan mengevaluasi pengaruh teknologi ensilage (dengan dan tanpa ensilage) dan sumber protein (nabati dan hewani) pada complete feed menggunakan limbah rami terhadap komposisi nutrien dan parameter ensilage. Perlakuan teknologi ensilage menurunkan komposisi nutrien pada bahan kering (BK), bahan organik (BO) dan neutral detergent fiber (NDF, meningkatkan kuantitas parameter ensilage pada asam asetat (C 2 ), asam propionat (C 3 ), asam butirat (C 4 ) dan asam laktat (LA) dan menurunkan pH serta tidak nyata pada protein kasar (PK), acid detergent fiber (ADF) dan ammonia (NH 3 -N). Perlakuan sumber protein menurunkan nutrien BO dan PK dan C 2 serta meningkatkan konsentrasi NH 3 -N secara sangat nyata pada complete feed dengan protein hewani. Interaksi kedua perlakuan berpengaruh pada PK dan pH serta C 2 dan C 3 . Kesimpulannya adalah penggunaan protein nabati pada silage complete feed menggunakan limbah rami lebih baik dari pada yang menggunakan protein hewani meskipun kedua jenis silage tidak lebih baik karena pH lebih dari 4,5.
