El objetivo del estudio fue determinar la respuesta de los metabolitos hepáticos: proteína, albumina, bilirrubina y enzimas hepáticas a diferentes edades de rebrote y niveles de inclusión de harina de hojas de Erythrina edulis. Se utilizaron 100 cuyes machos mejorados que se asignaron al azar 10 cuyes para cada tratamiento dietético que contenía 10, 20 y 30% de inclusión por 4, 8 y 12 meses de edad de rebrote y un grupo control con 20% de harina de alfalfa en condiciones isoproteicas e isoenergéticas. Se tomaron muestras de sangre con finalidad de determinar la actividad sérica mediante kits comerciales (Valtek Diagnostics) de los metabolitos hepáticos. En relación con los niveles séricos de proteína se observó un comportamiento similar en todos los tratamientos; la albumina, bilirrubina y enzimas hepáticas fueron diferentes (P≤0.05), mientras que la proteína (6.01 mg/d...

The objective from work was to evaluate the effect of diets based on Erythrina sp on the productive characteristics of the animal and its carcass. We used 32 male guinea pigs (Cavia porcellus) distributed in 4 treatments that received diets based on Erythrina sp (P) and commercial concentrated (C) feed in the proportions of 100:0% (Control), 75:25% (P75/C25), 50:50% (P50/C50) and 25:75% (P25/C75) respectively. To evaluate the effect of the diets on some productive characteristics and the technological properties of the carcass, was used a completely randomized design with a confidence level of 95%. The differences between averages were determined with Tukey test (P≤0.05). Diets supply to the animals produced variations (P≤0.05) on the increase of live weight and the yield of the carcass. Similarly, variations (P≤0.05) have been found in pH, water retention capacity and ca...

The experiment was carried out in the district of Tamburco, province of Abancay, Peru, between January and April 2017 and aimed to determine serum levels of creatinine, urea and blood urea nitrogen (BUN) in guinea pigs fed with pisonay (Erythrina sp). Leaves and petioles of pisonay with four months of regrowth and fresh alfalfa (Medicago sativa) with 28 days of regrowth were used in the diet of 18 improved male guinea pigs. The animals were distributed in three treatments: A100: 100% alfalfa (80 g), A50P50: 50% alfalfa (40 g) plus 50% pisonay (40 g) and P100: 100% pisonay (80 g). The feed was provided twice a day. Serum creatinine levels in guinea pigs fed A50P50 and P100 were significantly higher compared to those that consumed A100 (p<0.05). The BUN levels were only significantly different between A100 and P100 (p<0.05), while there were no significant differences between treatme...

The aim of this study was to evaluate the effect of three regrowth ages and three levels of inclusion of pisonay (Erythrina edulis) meal on feed consumption and conversion; body weight gain, and carcass rate in guinea pig fattening (Cavia porcellus). Shade-dried leaves and petioles of harvested trees were used and mechanically processed to 2 mm particle size. In total, 120 improved male guinea pigs were used, distributed in 10 treatments (3 regrowth ages, three levels of meal inclusion and a control group with alfalfa meal) for 56 days. The total and daily weight gain, in addition to the feed conversion had a similar response between treatments; feed consumption was lower with the 8M30% treatment (54.0 g/day) with respect to CA20% (59.3 g/day) (p<0.05) and the carcass yield was higher in 4M20% (73.5%) compared to the control diet (71.1%) (p<0.05). Feed consumption (60.3 g/day) as f...

Andean valley of Abancay is used the pisonay (Erythrina sp.) as green fodder to supplement in the dry season. It was evaluated the chemical composition, ruminal degradability and parameters ruminal kinetics of dry mater (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), hemicellulose (HEM) and cellulose (CEL) at 120 and 365 days regrowth of the pisonay. A 5-year Holstein dry cow was used, with a live weight of 600 kg and permanent ruminal cannula. Samples of 5 g of each age of regrowth / nylon bag were incubated at 0, 3, 6, 12, 24 and 48 hours. The parameters of the ruminal kinetics were determined using the RUMENAL procedure, SOLVER function. The nutritional composition at 120 days was higher in the CP, FDA and CEL and at 365 days the DM, NDF and HEM. DM, NDF and ADF at 120 days of regrowth were higher than 365 days in the degradable fraction and effec...

The objective from work was to evaluate the effect of diets based on Erythrina sp on the productive characteristics of the animal and its carcass. We used 32 male guinea pigs (Cavia porcellus) distributed in 4 treatments that received diets based on Erythrina sp (P) and commercial concentrated (C) feed in the proportions of 100:0% (Control), 75:25% (P75/C25), 50:50% (P50/C50) and 25:75% (P25/C75) respectively. To evaluate the effect of the diets on some productive characteristics and the technological properties of the carcass, was used a completely randomized design with a confidence level of 95%. The differences between averages were determined with Tukey test (P≤0.05). Diets supply to the animals produced variations (P≤0.05) on the increase of live weight and the yield of the carcass. Similarly, variations (P≤0.05) have been found in pH, water retention capacity and ca...

The study aimed to determine the chemical composition and ruminal degradability of dry matter (DM) and crude protein (CP) of Erythrina falcata at 105, 120 and 135 days of regrowth. Leaves and petiole samples were dried and 8 g of dry grounded samples were placed in nylon bags in the rumen of three male goats during 0, 24, 48 and 72 hours. The DM and CP values were 24.4 and 21.4% at 105, 24.8 and 23.2% at 120 and, 27.2 and 24.4% at 105 days respectively. The ruminal degradability of potentially degradable insoluble fraction of DM and CP was 29.6 and 42.9% at 105, 24.3 and 31.4% at 120 and, 14.9 and 24.1% at 135 days, respectively, and the effective degradability of DM and CP was 41.3 and 41.2% at 105, 36.5 and 30.3% at 120 and, 32.3 and 30.5% at 135 days respectively. The study showed a higher protein advantage in goats at 105 days of growth of E. falcata foliage.
