The aim of this study was to enrich guinea pig (Cavia porcellus) meat with omega3 polyunsaturated fatty acids by diets with omega-3 sources. A total of 48 male guinea pigs, 42 day old and 615 g body weight were used. The guinea pigs were randomly assigned to four treatments with three replicates (pens) with four individuals each. The dietary treatments were: 1) Control diet; 2) 1.0% fish oil supplemented diet; 3) 4.0% sacha inchi seeds (Plukenetia volubilis) supplemented diet; and 4) 1.0% fish oil + 4.0% sacha inchi seeds supplemented diet. The experiment lasted 28 days. The meat of guinea pig supplemented with fish oil contained 1.36% large chain omega-3 fatty acids (0.63% eicosapentaenoic acid [EPA] + 0.73% docosahexaenoic acid [DHA]) and those supplemented with the fish oil + sacha inchi had 0.99% large chain omega-3 fatty acids (0.44% EPA + 0.55% DHA). Guinea pigs on the control diet...

The aim of the study was to determine the productive parameters of guinea pigs raised with diets supplemented with fish oil and sacha inchi seeds. Forty eight male guinea pigs of 42 days old were used, with an initial body weight of 615 g. The guinea pigs were randomly assigned to 4 treatments with 3 repetitions (rearing pools) of 4 animals each. Dietary treatments were: T0: Control, T1: diet supplemented with 1.0% fish oil; T2: diet supplemented with 4.0% sacha inchi seed; and T3: diet supplemented with 1.0% fish oil + 4.0% sacha inchi seed. The experimental phase lasted 28 days. Body weight gain, feed intake, feed conversion and carcass yield were evaluated. The average of individual body weight gain ranged between 315 and 353 g per treatment, consumption ranged between 1172 and 1224 g dry matter, feed conversion ranged between 3.53 and 3.73 and carcass yield varied between 69.4 and 71...

El objetivo del estudio fue enriquecer la carne de cuy (Cavia porcellus) con ácidos grasos omega-3 mediante el uso de dietas con fuentes de omega-3. Se utilizaron 48 cuyes machos de 42 días de edad y peso inicial de 615 g. Los cuyes se asignaron al azar a cuatro tratamientos con tres repeticiones (pozas) de cuatro cuyes cada una. Los tratamientos fueron: 1) Dieta control; 2) Dieta suplementada con 1.0% de aceite de pescado; 3) Dieta suplementada con 4.0% de semilla de sacha inchi (Plukenetia volubilis); y 4) Dieta suplementada con 1.0% de aceite de pescado + 4.0% de semilla de sacha inchi. La fase experimental tuvo una duración de 28 días. La carne de cuyes alimentados con la dieta con aceite de pescado presentó 1.36% de omega-3 de cadena larga (0.63% ácido eicosapentaenoico [EPA] + 0.73% ácido docosahexaenoico [DHA]) y aquella con dieta con aceite de pescado más sacha inchi alca...

ResumenEl estudio fue conducido para evaluar el efecto de dos niveles de vitamina C (ácido ascórbico) del concentrado de cuyes en etapa de crecimiento y sin forraje verde, sobre la ganancia de peso, el consumo de materia seca y la conversión alimenticia. Se utilizaron 36 cuyes machos de 14 días de edad; después de cinco días de adaptación fueron distribuidos al azar en tres tratamientos con tres repeticiones (pozas) de cuatro cuyes cada una. Los tratamientos fueron: T1) grupo control (concentrado más rastrojo de brócoli); T2) concentrado con 5 mg de vitamina C estable y sin forraje y T3) concentrado con 10 mg de vitamina C estable y sin forraje. Los cuyes del grupo control (concentrado más rastrojo de brócoli) tuvieron mayor ganancia de peso vivo (p< 0,05), comparados con los cuyes del tratamiento que consumieron concentrado más vitamina C y sin rastrojo de brócoli. En cu...

The present study evaluated the effect of the inclusion of probiotic, prebiotic and the combination of both (symbiotic) in the diet on the productive parameters of guinea pigs (Cavia porcellus). Fifty 3-day-old male guinea pigs were selected from a Prolific-Dairy maternal line developed in the IVITA-El Mantaro Research Station (Peru) and randomly distributed in five treatments consisting of a basal diet of forages (rye-grass and red clover). supplemented with wheat bran (T5), plus probiotic (T1), prebiotic (T2), symbiotic (T3) and antibiotic growth-promoter (AGP) (T4). The probiotic was a mixture of six bacterial species isolated from the intestine and guinea pig faeces; the prebiotic was a commercial mannanoligosaccharide and the APC was Zn-bacitracin. The response to treatments was evaluated for 56 days in terms of body weight gain, feed intake and feed conversion ratio. No significant...

The aim of this study was to evaluate the effect of dietary supplementation with sodium butyrate (BS) on productive performance in fattening guinea pigs. Fifty 14-21 days old weaned male guinea pigs were randomly distributed in five treatments (0, 100, 200, 300 ppm of BS, 200 ppm of Zn-Bacitracin). Body weight gain, feed consumption and feed conversion were evaluated 70 days after supplementation. No response patterns were detected due to BS or Zn-Bacitracin treatments. It is concluded that, under the experimental conditions, supplementation with BS did not improve the productive parameters evaluated.

The present study evaluated the effect of supplementation with increasing levels of a liquid probiotic on the histomorphometry of the small intestine in guinea pigs. Fifty male guinea pigs were used from 3 days of age, distributed in a completely randomized design of five treatments with 10 repetitions each: 0, 1, 2 or 3 ml of probiotic or an antibiotic growth promoter (AGP, Zn-Bacitracin). Samples of duodenum, jejunum and ileum were taken from each animal at 84 days of age and the length and width of the intestinal villi, the depth of the Lieberkühn crypts and the length/depth relationship were measured. There were no consistent response patterns for most of the measurements in the three segments, except for a linear response (p=0.047) of the length/depth ratio in the duodenum and a positive effect (p=0.008) of the AGP over the length of villi in the ileum. It is concluded that, under ...

The aim of this study was to evaluate the effect of increasing levels of probiotic as zinc-bacitracin substitutes in the productive performance and intestinal morphology of fattening guinea pigs. Fifty weaned male guinea pigs were randomly distributed into five treatments consisting of supplementation with 0, 1, 2 and 3 ml of the probiotic "Guinea Pig Biomodulator" and an additional treatment with zinc-bacitracin. Body weight gain, feed intake and feed conversion during 70 days of growth, and intestinal morphology variables: villus length and width, Lieberkühn crypt depth, and villus length/crypt depth ratio were evaluated in the duodenum, jejunum, and ileum. Increasing probiotic levels linearly improved (p=0.008) feed conversion rate but had no effect on the other productivity components. In the intestine, only the length/depth relationship in the ileum was positively affected (p=0.026...

The aim of this study was to generate calibration equations to predict the nutritional chemical composition of the Italian rye grass (RG) (Lolium multiflorum Lam) by near infrared spectroscopy (NIRS). A total of 75 samples of RG of different harvesting weeks were collected from the IVITA Research Center in Huancayo (Peru). Spectrum capture was performed using NIRS and the chemical analysis was done for reference of the following components: crude protein (CP), ether extract (EE), total ash (CZ), crude fibre (CF) and neutral detergent fibre (NDF). A calibration and validation model by partial least squares (PLS) was developed and the correlation coefficient (R), coefficient of determination (R2), root mean square error of calibration (RMSEC), root mean square error of prediction (RMSEP), ratio range with error (RER) and residual predictive deviation (RPD) were used as statistics of accura...
