“…The time of pasture use is determined by a number of factors including severity of defoliation, fertilization (mainly nitrogen fertilization) (BELTRÁN et al, 2019), climatic conditions (rainfall, temperature, hours of light throughout the daytime), and phenotypic plasticity -a progressive and reversible change in the phenotypic characteristics of individual plants (LEMAIRE et al, 2009), considering that leaves are the main photosynthetic components of plants in addition to being higher nutritional value that are preferably harvested by the animal on pasture (WESP et al, 2016). Since all materials were influenced by the same soil and edaphoclimatic conditions and management, phenotypic plasticity may explain the longer period of pasture utilization of some cultivars.…”

Annual ryegrass is one of the species that best meets the needs of the farmers in south Brazil during the winter. Many of these cultivars can be found in the market. However, in some cases information on their actual adaptation to each climate situation or production system is unavailable. The present study aimed to evaluate the productive performance of diploid and tetraploid cultivars of annual ryegrass under grazing. The experiment was carried out in the municipality of Pato Branco, State of Paraná (PR), Brazil. The experimental design was a randomized complete block design with 4 replications. The following were the cultivars observed in this study: LE 284, Camaro, Bakarat, Estações, Ponteio and Nibbio (diploids; 2n), Winter Star, KLM 138, Scorpio, Titan, Barjumbo, and Potro (tetraploids; 4n). Mob grazing was used with an entry height of 25 cm and an exit height of 10 cm. It was noted that the cultivars that presented the longest period of pasture use were those that produced the greatest amount of forage. For all cultivars evaluated, the greatest accumulations of forage occurred between August, September, and October. Cultivars Winter Star (4n) and Escórpio (4n) stood out as they yielded the largest forage production. On average, tetraploid cultivars are more productive than diploid cultivars.

“…In this study, it was observed that feeds rich in fiber decrease the digestibility of the other components and the content of ME, results observed in several reports ( Fortes et al, 2010 ). The progress of the phenological state of the plant increases the content of the cell walls to the detriment of the nitrogen cell content ( Pérez, 2013 ; Beltrán et al, 2018 ). It has also been observed that the proportion of protein, EE, fiber, and ash was higher in the leaves than in the stems, as in the case of Phalaris tuberoarundinacea and flat corn ( Zea mays ).…”

To formulate economically viable foods and achieve high performance in guinea pig production it is important to know the nutritional value of the feeds, which requires determining their chemical composition, availability of nutrients, and energy content. Chemical analysis, digestibility tests, and digestible (DE) and metabolizable (ME) energy content of 63 feeds were determined using male guinea pigs of 4-5 months of age. The test feeds were fodder, agricultural residues, agro-industrial and kitchen waste, energy flours, and protein flours of animal and vegetable origin. The result showed a wide variability in the chemical composition and energy density of the feeds evaluated. In the case of forages, the main feed source for the guinea pigs, the average contents ± SD of crude protein, crude fiber, organic matter, DE, and ME were 18.06 ± 6.50%, 23.08 ± 7.14%, 89.95 ± 2.62%, 2963.71 ± 442.68, 2430.24 ± 363.00 Kcal/kg; for the agro-industrial and kitchen waste, the values were 11.52 ± 4.72%, 22.80 ± 14. 61%, 91.37 ± 4.74%, 3006.31 ± 554.01 and 2465.18 ± 454.29 Kcal/kg; for protein feeds the values were 55.18 ± 22.87%, 5.11 ± 5.72%, 91.18 ± 6.92%, 3681.94 ± 433. 24 and 3019.19 ± 355.26 Kcal/kg; for energy feeds the values were 12.73 ± 3.22%, 5.46 ± 1.96%, 95.33 ± 3.32%, 3705.41 ± 171.78 and 3038.43 ± 140.86 Kcal/kg. The ME content is directly associated with crude protein content (R 2 = 0.19) and organic matter digestibility (R 2 = 0.56) and inversely with crude fiber (R 2 = 0.40) and ash (R 2 = 0.13) content (P < 0.01). The results of this study can be used to design feeding programs for family and commercial guinea pig production for meat.

Uso De Equipamentos De Proteção Individual: Uma Comparação Dos Programas De Fomento Das Indústrias De Defensivos Agrícolas

O objetivo da pesquisa foi analisar as ações realizadas pelas empresas de defensivos, visando fomentar o uso de EPI por parte dos agricultores. Buscou-se descrever e analisar os programas de três empresas fabricantes de defensivos agrícolas para fomentar o uso dos equipamentos de proteção individual (EPI), e compará-los. As empresas, multinacionais de defensivos agrícolas, foram selecionadas com base no faturamento. Os resultados foram obtidos a partir de material disponibilizado nos sites das empresas, uma vez que não os responsáveis não retornaram o contato realizado pelo pesquisador. O trabalho desenvolvido pelas empresas mostra que a responsabilidade social e ambiental ultrapassa a venda dos produtos. Em parceria com Universidades, Institutos de Pesquisa, sindicatos rurais, cooperativas e entidades do agronegócio, as indústrias desenvolvem cursos, dias de campo e treinamento técnico sobre o uso de EPI. O programa da Bayer foi o que disponibilizava menos informações, prejudicando, a comparação com os demais. O programa da Syngenta parece ser mais organizado e avançado, talvez pelo maior tempo desde sua implantação. Os programas analisados têm buscado suprir as deficiências encontradas no âmbito da atividade rural.
