          Abstract

          Se colectaron cinco tractos digestivos de iguana negra (Ctenosaura pectinata) en estado silvestre en el estado de Morelos, México, para conocer la composición botánica de la dieta y el metabolismo ceco-cólico. Se observaron frotis realizados del contenido ceco-cólico para registrar la presencia de protozoarios, bacterias y parásitos intestinales existentes. Se obtuvo la media y desviación estándar de las características evaluadas. En el contenido ceco-cólico se identificaron las especies vegetales guamúchil (Phitecellobium dulce) y huizache (Acacia farnesiana). Se estimó en base a materia seca la porción vegetal que conforma la dieta, la cual se distribuyó en frutos (62,9%), hojas (30,6%), rebrotes (2,9%) y flores (3,5%). La región ceco-cólica se caracterizó por la concentración (mmol) de los ácidos grasos acético (68,9 ± 10,6), butírico (11,98 ± 5,7), propiónico (9,04 ± 1,5) y total (89,9 ± 15), con pH de 7,45 y concentración de nitrógeno amoniacal (7,4 ± 2,8 mg/dl). La microbiota que se observó fue el protozoario Nyctotherus spp. Las bacterias totales oscilaron en concentraciones 7 x 10 a 9 x 10/g, siendo las celulolíticas de 9,2 x 10 hasta 3,5 x 10/g de contenido cecal. Los parásitos encontrados son nematodos identificados como miembros de la superfamilia Oxyuroidea con 655 ± 265/g huevos y 6,300 ± 329 adultos/iguana. Se concluye que la fermentación de la región ceco-cólica de la iguana negra en estado adulto se comporta de manera similar como en las especies herbívoras, en las cuales la fermentación se manifiesta de acuerdo con el alimento consumido. La concentración dietaria de proteína cruda fue de 14,5% y energía de 2,193 Mcal/kg y son animales parasitados con oxiuros.

          Translated abstract

          Five digestive tracts of black lizards (Ctenosaura pectinata) from a wild population were collected in Morelos State, México, in order to identify the plant composition in the diet and the cecum-colic metabolism. Smears obtained from cecum-colic content were observed to register the presence of protozoa, bacteria and intestinal parasites. The average and standard deviation were estimated from the evaluated characteristics. The plants species Guamúchil (Phitecellobium dulce) and Huizache (Acacia farnesiana) were identified in the cecum-colic content. The vegetal content of the diet was constituted by fruits (62.9%), leaves (30.6%), buds (2.9%) and flowers (3.5%), dry matter basis. The cecum-colic portion was characterised by the concentration (mmol) of acetic (68.9 ± 10.6), butyric (11.98 ± 5.7) and propionic (9.04 ± 1.5) fatty acids, total fatty acids (89.9 ± 15), pH 7.45, and ammonia nitrogen concentration (7.4 ± 2.8 mg/dl). The microbiotic observed was the Nyctotherus spp protozoa. The total bacterial count ranged from 7 x 10(8) to 9 x 10(9)/g, cellulolytic bacteria ranged from 9.2 x 10(7) to 3.5 x 10(8)/g of cecal content. The parasites observed were nematodes identified as members of the Oxyuroidea superfamily, with 655 ± 265 eggs/g and 6,300 ± 329 adults/lizard. It is concluded that the fermentation of the cecum-colon region of the adult black iguana behaves similarly to that from herbivorous species, with fermentation being carried out according to the ingested food. Dietary concentration of crude protein was 14.5% and energy 2.193 (Mcal/kg), and they are animals parasited by oxiurids.

          Rates of rumen fermentation in relation to ammonia concentration.

          1. Four sheep were fed from automatic continuous feeders on whole barley fortified with graded levels of a urea solution. This approach was to a large extent successful in maintaining relatively steady states of rumen ammonia concentration. 2. Rates of barley fermentation in the rumen at various rumen NH3 concentrations were assessed by measuring the disappearance of barley dry matter from polyester bags suspended in the rumen of these sheep. 3. The minimal NH3 concentration for maximal rate of fermentation was estimated as 235 mg/l rumen fluid.
