The objective of this study was to determine the effect of feeding guinea pigs (Cavia porcellus L) – Peru breed with coffee (Coffea arabica) pulp meal on productive parameters during the rearing and fattening stages. A total of 35 female guinea pigs were monitored from 28 to 91 days of age, and fed with alfalfa and concentrate (1:1). The animals were randomly distributed in five treatments with inclusions of 0, 5, 15, 25 and 35% of coffee pulp meal in the concentrate. The addition of the coffee pulp meal to the concentrate did not affect body weight gain, feed conversion and sensory quality (appearance, odor, carcass color and meat taste) but had an inverse relationship with feed consumption. The highest carcass yields were obtained with the inclusion of up to 25% of coffee pulp meal in the concentrate. Therefore, coffee pulp meal, as an input to formulate guinea pig concentrates, has ...

The chemical characteristics and in vitro digestibility of eleven inputs, divided into three groups were determined: seeds (sacha inchi [(Plukenetia volubilis], castor [Ricinus communis] and chia [Salvia hispanica]), by-products derived from rice (nielen, husk and powder) and agro-industrial residues of tropical plants and fruits (sugarcane bagasse, coffee pulp, outer shell and mucilage of cocoa [Theobroma cacao], orange pulp [Citrus sinensis] and bean pod [Caesalpinia spinosa]) with potential in animal feed. The samples were collected in the Amazon region, Peru. Its proximal composition, crude fibre content (FC), neutral detergent fibre (NDF), acid detergent fibre (ADF), calcium and phosphorus, as well as in vitro digestibility and gross energy (EB) were determined. Oilseeds stood out for their high oil content, high energy value and an important source of calcium and phosphorus; sacha ...

The present study was carried out at the Institute of Research in Livestock and Biotechnology of the UNTRM, with the objective of characterizing bromatology of 20 food supplies available in the region, and to be used in domestic animal feeding. The determination of the chemical composition was done by means of proximal analysis, to determine dry matter (DM), crude protein (CP), crude fiber (CF), ethereal extract (EE), ash (A) and nitrogen free extract (NFE). In addition, the concentration of minerals Ca, P, gross energy (GE) was determined; and in those inputs with ruminant feeding ability, neutral detergent fiber (NDF) and acid detergent fiber (ADF) were determined. Inputs have been classified according to their nature in: cereals (corn), roots and tubers (cassava flour, potato and bitucón), fruit trees (banana meal, orange pulp, guava), and agroindustry byproducts (coffee pulp, cocoa ...

El objetivo de este estudio fue evaluar modelos de predicción de la composición química del pasto kikuyo (Pennisetum clandestinum) usando espectroscopía en el infrarrojo cercano (NIRS). Se recolectaron muestras de P. clandestinum del distrito de Florida-Pomacochas, Amazonas, Perú, en tres edades de la planta (45, 60 y 75 días después del corte) y dos épocas del año (lluviosa y seca). Se determinó el contenido de humedad (H), proteína cruda (PC), extracto etéreo (EE), fibra cruda (FC), cenizas y energía bruta (EB). Se obtuvieron los espectros de absorbancia en el rango de longitud de onda de 1100-2500 nm. Mediante funciones y scripts de Matlab 2015ª se implementaron modelos de predicción, completos y optimizados, mediante redes neuronales (ANN) y regresión por mínimos cuadrados parciales (PLSR). Los modelos optimizados usaron 18 longitudes de onda relevantes, determinadas...

El objetivo de la investigación fue predecir la composición química de harina de sangre bovina (HSB), mediante espectroscopia de reflectancia en el infrarrojo cercano (NIRS), de las fracciones: Humedad (H), Proteína Bruta (PB), Extracto Etéreo (EE) y Ceniza (C). Se recolectó sangre de ganado vacuno de 1.5 a 8 años de edad, del centro de beneficio municipal de Chachapoyas. Se prepararon 30 muestras de HSB previa cocción a fuego lento por una hora y secado en una estufa a 60 °C. Se tomaron espectros en NIRS 2500XL (Unity Scientific, USA) y de las muestras analizadas en laboratorio por el método proximal, se obtuvo los químicos de referencia para generar el modelo de predicción con el software UCAL Model, por la primera derivada y los métodos de regresión RLM/ACP, RLM y RCP y se obtuvo el coeficiente de determinación R2 de (0.93, 0.83 y 0.82); (0.74, 0.78, 0.19); (0.67, 0.79,...
