The study evaluated the effect of four types of drinkers and the addition of Vitamin C in the supplement on the productive performance and economic benefit of guinea pig (Cavia porcellus) reared during the dry season in the Mantaro valley, Junin, Peru. Four hundred weaned males, 14 ± 3 days of age from the experimental farm of the IVITA Research Centre were used in a completely randomized design with 2 x 4 arrangement factorial (with and without addition of vitamin C and four types of drinkers) using five experimental units for treatment and every experimental unit formed by 10 animals. The drinkers were the type of a bowl (POC), continuous recharge (REC), suction (SUC) and nipple (NIP). The quantity of vitamin C supplied was 12 mg/animal/day. REC and NIP drinkers allowed a major consumption of water than POC and SUC (p<0.05), but REC had a greater waste of water. A similar trend was...

The study evaluated the effect of various types of forage feeders on the efficiency offorage usage and on the productive and economic response of guinea pig (Caviaporcellus) breeding. A total of 250 weaned male of 15 days of age at the Mantaro valley,Junín, Peru were used in a completely randomized design with five treatments of foragesupply and five repetitions per treatment. Each repetition corresponded to a cage withten guinea pigs. Four forage feeders were evaluated: cylindrical mesh on the floor (CMP),hanging U shaped mesh (MCU), iron grilled with foot on the floor (PFP) and hopper meshin V shaped (TMV), plus the traditional method with the forage directly on the floor(DSP). The use of feeders improved forage consumption efficiency, total food consumptionand benefit cost ratio (p<0.05). MCU was the most promising feeder in terms of forageconsumption efficiency, body weight gain,...

The aim of the study was to evaluate the effectiveness of chlorine dioxide (CD), eucalyptus leaf extract - grapefruit seed (ELE-GS), seed extract - grapefruit pulp (SE-GP) on reducing the load of aerobic mesophilic bacteria, E. coli, and total coliforms in guinea pig carcasses (Cavia porcellus). It was used a completely randomized factorial design with seven treatments: T1 = Control, T2 = CD 20 ppm, T3 = CD 30 ppm, T4 = ELE-GS 3000 ppm, T5 = ELE-GS 5000 ppm, T6 = SE-GP 400 ppm and T7 = SE-GP 800 ppm, where each treatment had five replicates (carcasses), except T1 (n=6). All treatments were effective in reducing the load of aerobic mesophilic bacteria in relation to the control group (T1). In the case ofE. coli, T5 was more efficient than T1 (p<0.05), and in total coliforms, T3, T5, T6, and T7 were more efficient that T1 (p<0.05). It is concluded that the use of CD 30 ppm and ELE-GS...

El estudio evaluó el efecto de varias formas de suministro de forraje verde sobre laeficiencia del uso de forraje y la respuesta productiva y económica en la crianza de cuyes(Cavia porcellus). Se trabajó con 250 cuyes machos destetados de 15 días de edad en elvalle del Mantaro, Junín, Perú, utilizando un diseño completamente al azar con cincotratamientos de suministro de forraje, empleando cinco unidades experimentales portratamiento y cada unidad con 10 cuyes. Se emplearon cuatro tipos de comederos paraforraje: de malla sobre el piso en forma cilíndrica (CMP), malla colgante en forma de U(MCU), parrilla de fierro con patas sobre el piso (PFP) y tolva de malla en forma de Vcompartida (TMV), además del método tradicional de ofrecer el forraje directamente sobreel piso (DSP). El empleo de los comederos para forraje mejoraron la eficiencia enconsumo de forraje, consumo total de al...

El estudio fue realizado con la finalidad de evaluar la efectividad del dióxido de cloro (DC), extracto de hojas de eucalipto - semilla de toronja (EHE-ST) y extracto de semilla pulpa de toronja (ES-PT) en distintas concentraciones (ppm) sobre la reducción de recuentos promedios de bacterias aerobias mesófilas, E. coli y coliformes totales en carcasas de cuyes (Cavia porcellus). Se utilizó un diseño factorial completamente al azar con siete tratamientos: T1 = Control, T2 = DC 20 ppm, T3 = DC 30 ppm, T4 = EHE-ST 3000 ppm, T5 = EHE-ST 5000 ppm, T6 = ES-PT 400 ppm y T7 = ES-PT 800 ppm, con 5 repeticiones (carcasas) cada uno, excepto en T1 (n=6). Todos los tratamientos fueron eficaces en reducir los recuentos de bacterias aerobias mesófilas en las carcasas con respecto al control (T1) (p<0.05). En la reducción de E. coli, T5 fue más eficaz con respecto a T1 (p<0.05), y en la re...
