| Se determinó la composición botánica de la dieta del perro de la pradera (Cynomyx mexicanus), cabras y ovinos con la técnica microhistológica, durante cuatro estaciones del año, en un pastizal desértico mediano abierto, en el Rancho los Ángeles, propiedad de la Universidad Autónoma Agraria Antonio Narro de Saltillo, Coah., México. Durante la mayor parte del año los perros de la pradera seleccionaron mayor cantidad de pastos (79 % en promedio, en todas las estaciones del año) en comparación con cabras y ovejas. El total de gramíneas en la dieta de las cabras fue consistente (20 %) para las diferentes estaciones del año, mientras que, en la dieta de ovejas, esta clase de forraje alcanzó su máximo nivel durante el invierno (72 %) y el más bajo en verano (62... |

| ABSTRACT This study was conducted to investigate the effect of selective feeding habits on the quality of the ingested diet and the effect of feed restriction on the selectivity and behavior of goats in feedlots. Differences were found only in the amount of feed given to the animals, with a difference in the amount of feed rejected as a function of the nutritional level. Higher levels of orts were measured for those animals that received the ad libitum diet. For the composition of orts, differences were measured only in the ether extract fraction. Animals fed the ad libitum diet increased their intake of ether extract and energy, crude fiber, neutral detergent fiber, and acid detergent fiber. Thus, they had a preference for consuming the fibrous and... |

| The objective of this study was to evaluate the effectiveness of reusing a controlled internal drug release (CIDR) device for up to three times in the reproductive performance of dairy goats raised in the semi-arid zone of northeastern Brazil. Forty-five goats were allocated into three hormone treatments, as follows: CIDR1x, treated with new CIDR during nine days. Two days prior to device removal, injections of 75 µg d-cloprostenol and 300 IU equine chorionic gonadotropin (eCG) were administrated. For the other treatments, the same hormone protocol was used, differing only by the use of the same CIDR for a second time in CIDR2x and for a third time in CIDR3x. The interval from device removal to the onset of estrus (13.3 ± 1.1h vs. 13.8... |

| A high demand for Chilean cheese has resulted in increased cheese production. This increase represents an opportunity to promote the development of new markets, such as for small ruminant cheeses. However, little has been discussed regarding the extent to which cheese consumers consider small ruminant cheeses. We hypothesized that price is the main determining factor for purchasing cheese. The present study examined this previously unexplored aspect. The objective of this study was to identify the factors that contribute to the purchaser's response behavior, including purchase, usage and product possession. This study also aimed to provide preliminary information on cheese consumption in the Province of Santiago, Chile. A personal interview was conducted... |

| ABSTRACT: The aim of the present study was to assess two diagnostic techniques (California mastitis test (CMT) and the somatic cell count (SCC)) that can diagnose mastitis in dairy goats. Experimental infection was conducted using 20 mammary glands, a strain of Staphylococcus aureus, an infectious dose of 1.2x108CFU mL-1 and a volume of 1mL per mammary gland. The CMT and the SCC were used to detect subclinical mastitis. Bacterial culture (BC) was performed immediately after milk collection and was used as the gold standard. Four experimental time points were established (0, 24, 48 and 72 hours post-inoculation). Analysis of the ROC curve confirmed that the best combination of sensitivity and specificity were obtained with a cutoff point of 405.5, 6030.0... |
