La producción bovina con ordeño en Ucayali no tiene el desarrollo esperado a pesar de más de 25 años de investigación. La baja calidad nutritiva del forraje en oferta, la reducción de la producción forrajera durante la época seca, y las bajas productividades globales de los hatos en los fundos son las principales limitaciones que previenen el desarrollo de esta actividad. El Programa de Investigación Alimentaria para Producción Bovina con Ordeño ha diseñado investigación dirigida a resolver estas limitaciones. La búsqueda de germoplasma forrajero de alta calidad nutritiva y tolerante al estrés de humedad, la investigación en el potencial de las leguminosas forrajeras, el uso de suplementación estacional en época seca, y el manejo alimentario dirigido a una mayor eficiencia reproductiva son los componentes de la investigación planteada. Se describen los principales resu...

The aim of this study was to determine the pH and the count of mesophiles in black prochilodus (“boquichico”) meat (Prochidolus nigricans), from the markets of the city of Pucallpa, Ucayali. In total, 115 samples of boquichico specimens were collected from the 23 stalls distributed in the 5 markets of the city (5 samples per stall, considering the stall as a lot), through a non-probabilistic convenience sampling. The processing was carried out by measuring the pH of the meat and the analysis for the count of mesophiles with the SPC method (aerobic plate count). The averages of the pH values in boquichico meat by market were below the neutral value (pH=7.0), but were higher in the samples from markets 3 and 5; likewise, the mesophilic counts in meat exceeded the Maximum Allowable Limits in 4 of the 23 stalls (two from market N° 1, one from market N° 2 and one from market N° 3). It ...

The objective of the study was to characterize the biosecurity measures of the poultry farms located in the province of Coronel Portillo, Ucayali - Peru. Fifty-three farms distributed in the districts of Campo Verde, Yarinacocha, Manantay, Callería and Nueva Requena were evaluated through a survey to the manager of the establishment. The data collected was verified visually and through records. Biosecurity measures were evaluated according to compliance, being 1 = met and 0 = not met. Twenty-nine farms were in a sanitary void, so the data of uniformity of the flocks and the handling of feed were not obtained. Within the seven obligatory biosecurity measures, all the farms had a disinfection program and 98.1% had a disposal system for dead birds; nevertheless, no farm complied with the seven measures, being the biggest problem the lack of human capacity building, where only 15.1% of farm...
