Abstract:The objective of this study was to analyze the effect of the quantity and quality of the feed offered on the performance of male beef cattle, >6 months old, on intensive grazing systems in Uruguay. Two hundred and fifty-four results from different experimental trials (nexp=68) performed between 1991 and 2020 by different research institutions in Uruguay were compiled and analyzed. The experiments included feeding studies with cultivated pastures as a single nutritional source (nexp=61), as well as supplementation studies on the same type of pastures (nexp=49). Simple, quadratic, multiple linear regressions and recursive partitions were performed to synthesize the information. Quadratic relationships between forage allowance (FA) and average daily gain (ADG) were observed for the different animal categories and seasons of the year. Including other parameters such as initial body weight and supplementation with energy concentrates or silages allowed to predict the ADG of animals under a wide range of feeding alternatives. Briefly, low FA levels (≤1.75 %BW) limit animal performance to maintenance gain conditions (0.2 kg/day). To achieve adequate levels of ADG (0.6-0.7 kg/day), with a low to moderate FA (between 1.75 to 3.5 %BW), the nutritional value of pasture needs to reach at least level 3 of quality (>58 %ODM, >13 %CP, <50 %NDF, >21 %Leg and <19 %DR). These daily gains can be exceeded if the FA is >3.5 %BW (ADG in the range of 0.7 to 1.0 kg/day). The increased response in additional ADG (0.4-0.5 kg/day) by the effect of supplementation with energy concentrate was achieved with low FA levels (≤2.25 %BW). The prediction of additional ADG using a multiple linear regression parameter allows evaluating whether supplementation is appropriate.
Resumen: El objetivo del presente trabajo fue analizar el efecto de la cantidad y la calidad de alimento ofrecido sobre el desempeño de bovinos para carne machos, de más de 6 meses de vida, en sistemas pastoriles intensivos de Uruguay. Se compilaron y analizaron 254 resultados de diferentes trabajos experimentales (nexp=68) realizados por distintas instituciones de investigación de Uruguay entre los años 1991 y 2020. Los estudios incluyen trabajos de alimentación con pasturas cultivadas como única fuente nutricional (nexp=61), así como trabajos de
suplementación sobre ese mismo tipo de pasturas (nexp=49). Se realizaron regresiones lineales simples, cuadráticas, lineales múltiples y particiones recursivas de modo de sintetizar la información. Se observaron relaciones cuadráticas entre la asignación de forraje (AF) y la ganancia media diaria (GMD) para las diferentes categorías y estaciones del año. La inclusión de otros parámetros como peso vivo inicial y suplementación con concentrados energéticos o ensilajes permitió predecir la GMD de los animales bajo un amplio rango de alternativas de alimentación. Brevemente, niveles bajos de AF (?1,75 %PV) limitan el desempeño animal a condiciones de mantenimiento (0,2 kg/día). Para lograr niveles de GMD adecuados (0,6-0,7 kg/día), con AF bajas a moderadas (entre 1,75 a 3,5 %PV), se necesita que el valor nutritivo de la pastura alcance al menos el nivel 3 de calidad (>58 %DMO, >13 %PC, <50 %FDN, >21 %Leg y <19 %RS). Esas ganancias pueden superarse si la AF es >3,5 %PV (GMD en el rango de 0,7 a 1,0 kg/día). La mayor respuesta en GMD adicional (0,4-0,5 kg/día) por efecto de la suplementación con concentrados energéticos se logra con niveles de AF bajos (?2,25 %PV). La predicción de GMD adicional utilizando los parámetros de la regresión lineal múltiple permite evaluar la conveniencia de la suplementación.

Abstract: Pancreatic eurytrematosis (PE) is an under diagnosed and neglected parasitosis in goats and sheep in the Americas. Clinical and pathological features of PE are not well defined in small ruminants worldwide. Natural cases of PE in small ruminants were detected in the Federal District, Brazil. A survey of necropsy records, including epidemiological and clinicopathological data, in goats and sheep was conducted. Most cases of PE occurred during the rainy season in adult females, with an incidence of 12.9% in goats and 0.8% in sheep. Clinical signs varied from asymptomatic infections to anorexia, lethargy, weakness, marked weight loss and death in some goats. Overall, most cases of PE in goats and sheep were incidental necropsy findings with minor pancreatic lesions. Three goats, however, showed severe chronic pancreatitis, dilation of major pancreatic ducts with numerous trematodes present and marked abdominal fat necrosis. Morphological and molecular characterization of flukes
detected Eurytrema coelomaticum. Our findings shed light on the prevalence of E. coelomaticum infections in small ruminants in the region and highlight the possibility of severe and lethal cases in goats. PE must be further investigated in small ruminant populations in relevant livestock production regions of the Americas. |
