Se evaluó el efecto de un compuesto probiótico (CP) con Lactobacillus sp., Bifidobacterium sp. y Saccharomyces a una concentración 2×107 UFC·mL-1, sobre comportamiento productivo rendimiento carcasa cuyes parrilleros. utilizaron 64 macho hembra 28±3 días edad, pesos entre 384,3 453,2 g, criados en jaulas cuatro niveles alimentados alfalfa fresca suplemento balanceado 500 ppm inulina. Los tratamientos consistieron la administración oral 0,0; 1,0; 1,5 2,0 mL·animal-1 CP al inicio las semanas 3...
Essential oils have demonstrated beneficial effects on the productive parameters of poultry. However, impact nanoencapsulated essential oil blends (N–EOs) in diet laying hens has been little described. The objective research was to evaluate effect mixtures N–EOs diets Lohmann Brown percentage laying, quality, and oxidative stability egg product. 600 birds were randomly distributed into five groups (n=150 per group), according a completely randomized design, receiving control group (T0)...
El objetivo del estudio fue comparar los parámetros productivos de vacas Bos taurus × indicus en sistemas producción semi estabulado y extensivo tres localidades trópico alto Oxapampa, Perú. Se evaluaron 325 criollas provenientes 18 unidades agropecuarias, analizando siguientes parámetros: diaria leche (PDL), peso al nacimiento (PN), duración la lactancia (DL), destete (PAD), tasa permanencia el fundo (TPVF) porcentaje (PVP). No se encontraron diferencias significativas (P=0,4998) PDL según...
A shock compaction technique has been successfully applied for the consolidation of hard magnetic powders without appreciable changes in phase structure and grain size. Pr–Fe–B Sm–Fe–N materials, prepared with application melt spinning mechanical alloying, respectively, were compacted a wave speed 1200 m/s pressure 4.4 GPa. We found that coercivity high RE containing material, which hardness is controlled by good separation grains RE-rich paramagnetic phase, decreases slightly, ∼5 %, due to...
An experimental study (15-wk-old ISA Brown pullets) was conducted to establish the efficacy of essential oil Eugenia caryophyllata against Salmonella enterica serovar Enteritidis. The trial composed 4 groups. Pullets in groups 3 and were fed with a commercial compound feed, pullets 1 2 same feed plus aromatic product at dose 250 g/Tm. At 19 wk old, infected individually an inoculum 3.2 ± 0.8 × 107 cfu Enteritidis/ pullet. During postinoculation period, samples feces eggs cultured, killed 30...
The objective of this systematic scientific review was updated bibliographic information concerning the genetic, morphological, zootechnical and meat potential creole pigs in Central South America. It found a population 73 million Creoles Latin America, most under extensive, semi extensive production systems. Since its European origin, adaptation to different ecosystems on continent introduction new breeds has led into wide variety pigs. Adaptation have also rise genetic variability...
An enhancement of the Curie temperature, T/sub c/, was deduced from ac-susceptibility measurements on R/sub 2/Fe/sub 14/B (R=Nd and Pr) phase for exchange coupled nanocrystalline magnets with respect to corresponding microcrystalline magnets.
The objective of this research was characterize and determine the effect native strains Azotobacter spp. on vegetative growth Lycopersicon esculentum Mill. "Tomato" as an alternative to indiscriminate use chemical fertilizers. Samples were taken from roots rhizosphere soil vegetables which dilutions (10-4) in Ashby-sucrose broth incubated at 30 °C observe a yellow color, turbidity surface film. genus identified mineral agar without nitrogen Ashby-benzoate, obtaining 96 with yield 7.10 57.99...
This research was conducted to characterize and determine the effect of native strains Azospirillum spp. on growth Oryza sativa L. "rice" as an alternative for reduction chemical fertilizers. The bacteria were isolated from roots rice in Lambayeque. Fragments previously disinfected planted Nfb semisolid medium, nitrogen-fixing recognized by a whitish film surface turn green blue. genus identified Congo red agar obtained 96 isolates with production 2.69 38.02 ppm indoleacetic acid 7.95 29.09...
The present study evaluated the effect of supplementation with oregano essential oil (OEO) on productive parameters, oxidative stability, and lipid parameters turkey meat.Eighty 1-d-old male turkeys were randomly distributed into four treatment groups fed following diets for 105 days: control diet without any or 300 mg/kg lincomycin spectinomycin, 100 OEO, 200 OEO.Supplementation OEO obtained best bodyweight, average daily gain, feed conversion, lowest intake concerning other (p < 0.001),...
Diets supplemented with halquinol and/or nanoencapsulated essential oils (N-EOs) have shown positive effects on the productive parameters of broiler chickens. However, there is limited comparative evidence between these two products. This study aimed to investigate and compare efficacy N-EOs blends as dietary supplements for A total 500 male Cobb chickens were randomly assigned five groups. The control group received a conventional diet (60%), while experimental groups supplementation...
The objective of this research was to determine the degree food competition between guanaco and livestock in Calipuy National Reserve. Vegetation cover (CV) determined by a survey vegetation composition diets using micro histological technique feces (50 guanacos, 35 cows 25 horses). dietary overlap Horn Index (I), preferences Ivlev index (E) diet diversity Shannon-Weaver (D) .We found low - moderate cattle horses. greater during rainy season (I=0.80 0.88) where forage supply high (CV=63%)...
