“…In a Colombian study, meat from zebu cattle raised in four production systems (two silvopastoral systems, improved pasture and a traditional grazing system) was compared [ 139 ]. Myristic and palmitic acids were higher in meat from the traditional (3.65 and 32.6 g/100 g of TFA, respectively) than the improved pasture system (2.82 and 28.9 g/100 g of TFA, respectively), while linolenic acid was lower (0.96 vs. 2.30 g/100 g of TFA).…”

Cattle production in tropical regions has been estimated to account for just over half of cattle worldwide, yet it has not been demonstrated that sufficient similarities in the cattle exist to describe tropical cattle and, even less so, to characterize the meat from these animals. The aim of this review is to investigate the quality and nutrient composition of meat from cattle raised in the Tropics to determine if there is an axiomatic basis that would allow the definition of a concept of “tropical beef”. Tropical beef is the meat obtained from cattle raised in tropical environments, the population of which remains largely uncharacterized. Production systems in the Tropics are highly diverse but converge on the use of indigenous and Bos indicus breeds or Bos indicus-influenced crossbreeds under pasture feeding regimes. While some systems allow cattle to be slaughtered at ≤2 years of age, most often animals are ≥3 years. These production systems generally produce lean, low-yielding carcasses and tough (>46 N), lean (≤3.6% intramuscular fat) meat with a macronutrient composition otherwise similar to beef from animals raised elsewhere (72–74% moisture and 20–24% protein). Fatty acid profiles depend on the breed and production systems, while mineral content is influenced by the environment. Although lean and tough, tropical beef is highly acceptable to the consumers it serves, is culturally and traditionally relevant and, in many countries, contributes to food security. Consolidating the findings from animal and meat science studies in the Tropics has allowed the demonstration of an axiomatic basis defining “tropical beef” as a concept.

“…Opio et al (2013) estimated that in the production of one kg of beef carcass weight, there is an emission of 67.8 kg of CO2 equivalent, of which 28.9 kg correspond to enteric methane emissions. In our experiment, with a dressing percentage of 52% (Montoya, 2015), enteric methane emissions for the production of one kg of beef carcass weight would be 13.7 and 34.2 kg of CO2 equivalent in ISS and M. maximus pastures, respectively.…”

Knowledge of forage intake and grazing selectivity is vital to improve the use of feed resources by grazing animals. To estimate forage selectivity and intake by steers grazing in intensive silvopastoral systems (ISS) under tropical dry forest (bs-T) conditions. Intake was evaluated using the n-alkane technique in: 1) a Leucaena leucocephala (over 10000 shrubs/ha) and Megathyrsus maximus ISS system and, 2) a M. maximus monoculture system. Eight steers with an average weight of 248Â±23.1 kg live weight were evaluated. Animals grazing in the ISS system had greater dry matter intake (26.1 vs. 20.4 g kg-1 d-1 of BW, P = 0.044) and had greater intake (g d-1; P â‰¤ 0.02) of crude protein (954 vs. 499), calcium (62.1 vs. 36.2) and fat (94.2 vs. 69.6) than those grazing in the M. maximus monoculture system, respectively. Compared to conventional pastures, DMI of animals grazing in ISS increases, contributing to greater animal productivity.

“…Por otra parte, la mayor concentración de mono y poliinsaturados encontrada en la HSSPi con respecto a HST, puede explicarse por el efecto de la carne. En este sentido, son varias las investigaciones que describen el efecto favorecedor de los sistemas silvopastoriles sobre la composición lipídica de la carne, observándose un mayor contenido de ácidos grasos poliinsaturados en comparación con el ganado alimentado con grano [30,32,49,50,51].…”

Desarrollo de hamburguesas con la adición de nuez criolla pecana (Carya illinoinensis) y fibra de trigo (Triticum aestivum), empleando carne de toretes alimentados con dos sistemas de engorde

El objetivo de esta investigación fue evaluar el efecto del empleo de nuez pecana, fibra de trigo y carne bovina obtenida de toretes engordados bajo un sistema silvopastoril intensivo (SSPi), sobre las propiedades fisicoquímicas, microbiológicas y sensoriales de hamburguesas. Mediante un diseño de mezclas se obtuvo la mejor formulación de la hamburguesa empleando como variables independientes los porcentajes de carne de toretes engordados bajo un sistema tradicional (ST), nuez pecana, fibra de trigo, aditivos y mezcla de vegetales, considerando como variables de respuesta el color, sabor, olor, textura y contenido de grasa. La mejor formulación obtenida del diseño fue replicada empleando carne de vacuno SSPi y se elaboró además una tercera formulación control con carne ST y sustituyendo la nuez y la fibra por grasa bovina. A las formulaciones resultantes se les realizó controles físico–químicos, perfil de ácidos grasos, análisis microbiológicos y evaluación sensorial mediante análisis cuantitativo descriptivo. La mejor formulación sugerida por el diseño estuvo compuesta por 65,7 % de carne ST: 11,1 % de nuez pecana; 1,1 % de fibra de trigo; 6,1 % de aditivos y 16 % de mezcla de vegetales. Las formulaciones elaboradas con adición de nuez y fibras (HST y HSSPi) resultaron significativamente superiores desde el punto de vista físico–químico y sensorial a la hamburguesa control (HC), con menores porcentajes de grasa, mejores propiedades de cocción y mayores contenidos en ácidos grasos poliinsaturados, así como una mejor aceptación sensorial, destacándose significativamente en estos parámetros la formulación elaborada con carne SSPi. Desde el punto de vista microbiológico no se encontraron diferencias significativas y todos los productos resultaron microbiológicamente aceptables cumpliendo con los parámetros establecidos en las normas.
