El proyecto pretende mejorar la eficiencia de la producción lechera y garantizar que los pequeños productores no se queden atrás en la búsqueda del desarrollo. Para ello, el proyecto busca específicamente (i) co-crear una plataforma digital de recolección y análisis automatizado de datos para la toma de decisiones estratégicas en función a las características propias de las pequeñas explotaciones lecheras y (ii) fortalecer las capacidades de los socios locales para desarrollar e implementar soluciones tecnológicas basadas en conceptos y mecanismos de IoT para diseñar, prototipar, codificar y probar softwares para mejorar la gestión ganadera. Como resultado de este proyecto, se espera un aumento de la resiliencia y de los ingresos de los pequeños ganaderos peruanos. Asimismo, se espera posicionar a la UNALM y al INIA a la vanguardia de la producción lechera sostenible y la...

The study aimed to determine the effect of three levels of selenium on the diet of growing guinea pigs. Thirty-three weaned guinea pigs, 12 days old and with an body weight of 258 ± 35 g were randomly distributed in three treatments whose only difference was the content of selenium in the feed: 0.10, 0.17 and 0.24 mg Se/kg of feed for T1, T2 and T3, respectively. The animals received a ration without forage supply, with vitamin C supplementation and were housed in individual cages with individual feeders and had free access to feed and water. The daily feed consumption and the weekly body weight were recorded. No significant differences were found between treatments for body weight gain, feed intake and feed conversion.

The aim in this study was to determine the chemical composition, digestibility, and methane production of Echinochloa polystachya (Kunth) Hitch in periods with different rainfall in the Peruvian rainforest region. The pasture was managed under a rotational grazing system. The nutritive quality and in vitro CH4 production of the pasture during both experimental periods was determined from a sample obtained by zigzag technique and sampling points using the method of destructive systematic sampling. Echinochloa polystachya in the period of lower than higher rainfall had a higher content of neutral detergent fiber (NDF) (p < 0.001) and acid detergent fiber (ADF) (p < 0.001). Organic material (OM) was higher in the period of greater rainfall (p < 0.001); however, the crude protein (PC) content (p = 0.11), in vitro digestibility of OM (p = 0.89), corrected net gas production (p = 0.83...

El estudio fue realizado en un zoocriadero de ronsocos (Hydrochaeris Hydrochaeris) en la ciudad de !quitos y tuvo una duración de 90 días. Se evaluó el efecto de suministrar Subproducto de Trigo (SPT) sobre el crecimiento de ronsocos bajo cautiverio alimentados congramíneas tropicales. Los tratamientos fueron TA: SPTal1% del P.V. del animal, y T B: SPT al2% del P.V. del animal. Se encontró diferencias significativas entre tratamientos en cuanto al incremento diario de peso: 1% SPT (67.9 g) y 2% SPT (90.3 g). En cuanto al consumo total de materia seca como porcentaje del peso vivo (P.V.), se observa un mayor consumo por parte de los animales con2% de SPT (4.32 %) conrespecto a 1% SPT (3.76 %), observándose así un efecto Aditivo de la suplementación de concentrado sobre el consumo de materia seca. La conversión alimenticia no fue afectada: 1% SPT (7.63) y 2% SPT (7.40). El ...

The objective of this study was to assess the effects of saponins derived from Chenopodium quinoa by-products on methane (CH4) production in a ruminal fermentation system under in vitro conditions. Additionally, the study included the analysis of short-chain fatty acids (SCFAs) and true dry matter digestibility (TDMD). The saponin extracts obtained from three quinoa varieties were Altiplano (AS), Quillahuaman (QS), and Salcedo (SS), and were tested at six different doses (0, 0.2, 0.4, 0.6, 0.8, and 1.0mg/mL) each. Rumen fluid was obtained from two fistulated Junín breed sheep, with alfalfa hay (AH) and a 1:1 mixture of maize and bran (MB) was used as basal substrates. The data were processed in a completely randomized design and replicated three times. The CH4 per dry matter (mL/g DM), after 24h of incubation significantly decreased, acetate molar concentration decreased (p<0.05) with A...

El objetivo del estudio fue evaluar el efecto de un suplemento mineral orgánico en la alimentación de vacas lecheras sobre la producción y calidad de leche, para lo cual se utilizaron 27 vacas de raza Holstein, distribuidas de manera aleatoria en dos grupos: experimental (T1) y testigo (T2), con 14 y 13 animales, respectivamente. Las vacas en evaluación fueron animales de segundo y tercer parto. La alimentación se basó en una ración compuesta por broza de espárrago como forraje, concentrado para vacas en producción y complementado con residuos de turión y alcachofa. El suplemento mineral orgánico fue suministrado individualmente en proporciones de 150 g/día en el periodo pre parto (tres semanas) y 214 g/día en el postparto (cuatro semanas). Las vacas fueron ordeñadas tres veces al día. Para la evaluación, se controló la producción de leche semanalmente y se sacaron mues...

The effect of multinutritional blocks (BMN) based on agro-industrial residues on the production and composition of bovine milk in a tropical region of Peru was evaluated. For the elaboration of the BMN, agro-industrial residues from the processing of rice (rice polishing) and coconut (cake) were used. Twelve native cows were used to graze in paddocks with Brachiaria brizantha distributed in two groups (A and B) of six animals during two periods of 21 days each. Two treatments were established: T0 (grazing without supplementation) and T1 (grazing plus supplementation with BMN). During the first period, group A received T1 and group B received T0, while in the second period the reverse was done. Daily milk production (kg/day), milk composition (protein, fat, lactose, total solids, %) and the level of urea in milk (mg/100 ml) were measured. The change-over design was used to analyze the res...
