As more attention is paid to the integral management and the problems of cattle production systems in the achievement of sustainable productivity and competitiveness in the territories of the Colombian Amazon region, it is necessary to determine the socioeconomic factors that affect the use of the potential and comparative advantages of productive units located in the region for nutritional supplementation from local inputs, such as Non Timber Forest Products (NTFP). For this purpose, a descriptive-cross-sectional scope with non-experimental design and quantitative approach study was carried out, applying the collection instrument to the sample size defined in a nonprobabilistic way in the municipalities of Albania San Vicente del Caguán, El Doncello, Puerto Rico, and Cartagena del Chaira of the department of Caquetá Colombia. Information was systematized using the R software, where the principal component analysis of the socioeconomic factors with the use of cattle nutrition in the NTFP was carried out. It was found that the factors that have the greatest impact on the use of NTFP are related to the degree of knowledge about NTFP and the strategies for the transfer of scientific knowledge as a complement to the knowledge of the producers.
The present work determined the nutritional quality of Piptocoma discolor and Cratylia argentea as non-timber forest products used in animal feed in the Amazonian foothills in Caquetá province - Colombia, where the grasses B. decumbens and B. humidicola predominate in the pastures.A random selection of 50 farms was made, identifying that in each of them the shrub species Piptocoma discolor, Cratylia argentea and areas of grasslands for grazing where Brachiarias decumbens and B. humidicola predominate. One sample per species was taken from each farm. The samples were subjected to chemical analysis (CP, ADF, NDF, ADL, cellulose, hemicellulose, EE, ash and IVDDM, OMD, TDN, DE, ME). An analysis of variance was performed for each of the variables evaluated using a linear mixed model, considering the species factor as a fixed effect and municipality was considered a random effect. The model assumptions were evaluated by graphical inspection of residual. A multivariate synthesis to see the interrelation between variables and species was performed using a biplot graphic obtained by principal component analysis. C. argentea and P. discolor presented higher CP levels than the grasses in the pastures (17.7; 13.1; and 6.15%, respectively) with good levels of energy intake, confirming that C. argentea and P. discolor are non-timber forest resources with forage potential.
The study was conducted at the Amazon Research Center CIMAZ - MACAGUAL of the University of Amazonia, Colombia, with a tropical rain forest climate (Af). The behavior of Bos taurus, Bos indicus, and Caqueteño Creole cattle, the animals were observed in paddocks with three levels of scattered tree cover density. The pasture was composed of Braquiaria decumbens with 35 days of regrowth. Direct observations were made from 9:00 a.m. to 5:00 p.m. with 10-minute intervals between the recording of the activities. The activity performed most often during the day by all of the animals was grazing under the sun, and those who pasture the most are the Caqueteño Creole, followed by the Bos indicus and, finally, the Bos taurus. Ruminating was the second most important activity performed by the cattle, having presented the same tendency. In the paddocks with a low level of tree cover, the animals pasture more in the shade; this trend is more relevant among B. taurus cattle. Caqueteño Creole cattle dedicate less time to water consumption and rest, spending more time grazing, in the high and medium cover levels, they interrupt the grazing at noon for a shorter time compared to B. indicus and B. taurus; after 2 p.m., the creoles vertiginously increase grazing. At the high cover level, the peak of grazing of the Caqueteño Creoles is at 9 a.m. and from 1-1:30 p.m., while at the medium tree cover level, the peak of pasturing was at noon, 1:30 p.m., and 4:30 p.m., at the high tree level of cover, the peak for the three breeds was at 11 a.m. Only at the average tree level of cover did the Caquetaño creoles and B. indicus present a similar peak. In 9-9:30 a.m. and 4-5 p.m., the breeds substantially reduce rumination.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
