A survey was conducted in July 2004 to 160 families rearing Guinea pigs in the district of Santa Cruz, Cajamarca, with the aim of characterizing the production system of these animals. Men were more than 50 years of age (44.6%) and wives were mainly between 31 to 50 years old (42%). Primary school was the main grade of instruction. The main labour activity of the head of the family was agriculture (95.4%) and housekeeping for women (97.2%). Raising guinea pigs was mainly driven by the housewife under a family or traditional system. There were 20.4 guinea pigs on average per family, reared regardless of class, sex and age, preferably in the kitchen (88.8%), free (73.8%) or in pools (21.9%). Feeding was based on forages, weeds and kitchen waste. The main diseases reported were ectoparasites (90.1%) and the «plague» (76%). Guinea pigs were used for consumption and sale (71.2%) or only for...

The objective of the study was to determine the presence of Mycobacterium avium subsp. paratuberculosis (Map) in dairy cattle in Lima, Peru. The Intradermal Tuberculin Test was applied to 60 cows from three herds and serum samples were tested using two commercial ELISA kits for antibodies against Map. Twenty-two cows (36.7%) were positive to at least to one of these diagnostic techniques (8 to one of the ELISA tests and 18 to the intradermal test). Feacal samples from the 22 positive animals were cultured on Herrold’s egg-yolk medium (HEYM) yielding five Map positive samples. PCR was used in the isolated strains and Map DNA was confirmed in two cows. A slight concordance (0.15, Kappa test) was found between techniques evaluating cellular and humoral immune response, establishing that these tests are not interchangeable (5.55> 3.84, Mc Nemar test). The results confirm the presence of...

Se realizó una encuesta en julio de 2004 a 160 familias criadoras de cuyes en el distrito de Santa Cruz, Cajamarca, con el objetivo de caracterizar los sistemas de producción de cuyes. El 44.6% de los productores tenía más de 50 años de edad y el 42% de las esposas tenía entre 31 a 50 años. Primaria era el grado de instrucción predominante. La ocupación del jefe de familia era la agricultura (95.4%) y de la esposa era su casa (97.2%). La crianza de cuyes era conducida por el ama de casa bajo un sistema familiar o tradicional. Se encontró un promedio de 20.4 cuyes por familia, criados en un solo grupo sin distinción de clase, sexo y edad, de preferencia en la cocina (88.8%), donde permanecían sueltos (73.8%) o en pozas (21.9%). La alimentación se basó en forrajes, malezas y residuos de cocina. Las principales enfermedades reportadas fueron ectoparásitos (90.1%) y la “pest...

El presente estudio tuvo como objetivo evidenciar la presencia de Mycobacterium avium subsp. paratuberculosis (Map), en el ganado bovino lechero del departamento de Lima, Perú. Se evaluaron 60 vacas procedentes de tres establos, mediante la prueba tuberculínica intradérmica y dos kits comerciales de ELISA específicos contra Mycobacterium avium subsp. paratuberculosis. Resultaron positivos 22 animales (36.7%) a una de las tres técnicas diagnósticas (8 a una de las pruebas de ELISA y 18 a la prueba intradérmica). Se tomó muestras de heces a los 22 animales positivos y se cultivaron en el medio de Herrold con yema de huevo, resultando cinco muestras positivas al aislamiento de Map. Asimismo, se realizó el PCR a partir del cultivo, encontrándose dos muestras positivas. Se encontró una concordancia ligera (0.15, prueba Kappa) entre las técnicas que evalúan la respuesta inmune cel...

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 present study aimed to determine the quantitative echographic pattern of abdominal organs of the domestic rabbit. Ultrasound examination was performed in 16 New Zealand mature rabbits (11 females and 5 males). Descriptive measurements were obtained for liver (diaphragm hilum, dorsal ventral and transverse diameter), gallbladder (length and thickness), gastric wall, urinary bladder (wall, length and thickness), spleen (length, thickness and transverse diameter), kidneys (length, thickness and cortex), prostate (length, thickness and diameter) and uterine body.

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...
