“…The NDIP of the first and second crop was higher at harvest and baling, respectively ( Table 2), results that were in agreement with those reported by Castagnara et al (2011). Pasqualotto et al (2015) showed that NDIP is reduced with time when hay production occurs under high conditioning intensity, whereas no change was observed when hay production occurs under low conditioning intensity.…”

The objective of this study was to evaluate Cynodon species 'Tifton 85' at different hay production phases (harvest, baling, and storage) and different (N) rates. Dehydration of the first crop was carried out in the field, while the second crop was in the shed. Dry matter and protein content increased linearly with the N rates. Dehydration in the shed was not effective for hay production, since dry matter did not reach the desired level of 850 g kg -1. During the hay production period (harvest, baling, and storage), the content of acid detergent fiber of the first crop and the second crop increased by 25.32 and 7.38%, respectively, and that of lignin increased by 21.33 and 32.27%, respectively. Forage digestibility decreased by 4.55%, when dehydration occurred in the field, whereas it decreased by 14.68% when dehydration occurred in the shed, a difference higher than 300% due to the loss of soluble carbohydrates. Overall, the findings of this study indicate that forage dehydration for hay production needs to be carried out in the field under appropriate environmental conditions to prevent nutritional losses. Additionally, dry matter of Tifton 85 increased by 20.40% and protein content increased by 18.65%, which equals 514.27 kg of soybean meal at 100 kg ha -1 of N.

“…In the class of green bulky, the pastures of Tifton 85 stood out at 61.02% of the properties in the summer and 38.81% of the properties in the winter. Tifton 85 is a forage grass that is traditionally used in western Paraná, both for grazing and for hay production (CASTAGNARA et al, 2011). It is worth noting that some properties adopted new forage technologies for animals in order to provide new forage species that are distinct from those that are traditionally used, such as the Aries grass (Panicum maximum cv.…”

The dairy industry is characterised by a wide diversity of production systems. In this diverse environment, some of the difficulties can be minimised through the grouping of production units through the study of typology. The objective was to characterise the systems of milk production from West Parana State by considering production rates, area, power, facilities, and marketing of milk. To this end, 735 semistructured interviews with dairy farmers were performed by using a questionnaire for management practices and feed that is used on the farms. To obtain the explanatory variables used for principal component analysis (PCA) and hierarchical cluster analysis (HCA), a homogeneous division of 735 farmers in five groups was used. Ten per cent of producers were randomly selected for the performance of field visits to the properties, where a new questionnaire was applied with specific points regarding feeding management on the property, and feed was collected to determine its composition. The collected data were tabulated and feed was ranked based on the classification proposed by the NRC (2001). Analyses of feed were carried out in the Laboratory of Animal Nutrition of Unioeste. The West Parana State has five groups of dairy production systems. There is great variability in the fresh forages that are used, but maize silage is the main forage utilised for fermented feed, and concentrate supplementation is adopted by more than 60% of farms during both seasons. Changes in the levels of feed components are high among systems. Key words: Animal feed. Characterisation of production. Composition of foods. Dairy farming. ResumoA pecuária leiteira é caracterizada por ampla diversidade de sistemas de produção. Nesse ambiente diverso, algumas das dificuldades podem ser minimizadas por meio do agrupamento das unidades de produção através do estudo da tipologia. Objetivou-se caracterizar os sistemas de produção de leite do Oeste do Estado do Paraná considerando os índices de produção, área, alimentação, instalações e comercialização do leite. Para tal, foram realizadas 735 entrevistas semiestruturadas, com produtores de leite, utilizando um questionário guia referente a práticas de manejo e dos alimentos utilizados nas propriedades. Para a obtenção das variáveis explicativas usou-se a análise de componentes principais (ACP) e análise de clusters hierárquicos (CHA), obtendo-se a divisão homogênea dos 735 produtores em cinco grupos. Destes foram selecionados ao acaso 10% dos produtores cada para a realização das visitas a campo nas propriedades, aplicando-se um novo questionário que contemplava pontos específicos do manejo alimentar utilizado na propriedade, bem como a coleta de alimentos para determinação da sua composição. Os dados coletados foram tabulados e os alimentos classificados com base na classificação dos alimentos proposta pelo NRC (2001). As análises dos alimentos foram realizadas no Laboratório de Nutrição Animal da Unioeste. O Oeste do Estado do Paraná possui cinco grupos de sistemas de produção leiteira. ...

“…Low levels of fraction A at 30 days of storage can be attributed to the high levels of dry matter recorded in hays (mean of 876.62 kg ha -1 ), an indication of the occurrence of less proteolysis during storage. The main alteration in the chemical composition of hay occurs in the first 30 days of storage, which may have affected the A fraction (CASTAGNARA et al, 2011).…”

“…Milk production in western Parana is based on the use of tropical grasses in pastures or conserved in the form of silage or hay. The use of forage preserved in the form of hay is a very common practice used by farmers as an alternative to solve the problem of the seasonality of fodder, and to allow the best use of the surplus; however, the storage of forage for long periods of time may cause changes in nutritional value (CASTAGNARA et al, 2011) Tifton 85 bermudagrass hay stored up to 90 days in a covered shed. The cutting height of the forage for haying can influence the nutritional value of the forage by affecting dry matter production, since cutting heights closer to the ground increase mass production, but these also include senescent parts that contribute to reduced nutritional value of the hay.…”

This study aimed to evaluate the fractionation of carbohydrates and protein of grass hay Tifton 85 bermudagrass under two cutting heights in relation to ground level (0.04 and 0.08 m) during 120 days of storage. Samples were collected in the baling and hay stored in shed at 30, 60, 90 and 120 days of storage, after, it was subjected to laboratory procedures, in which the levels of soluble carbohydrates were determined, carbohydrate fractionation and protein fractionation. The results were studied in a randomized complete block design with split plot with two treatments allocated the plots: cutting height of 0.04 to 0.08 m from the ground and five times in the subplots: baling, 30, 60, 90 and 120 days of storage hay, with five repetitions. The soluble carbohydrate concentration hay responded in a quadratic manner to the storage time for cutting heights of 0.04 and 0.08 m above soil level; minimum values of 11.53 and 10.70 g kg-1 of DM were estimated for 93.44 and 91.16 storage days, respectively. The carbohydrate fraction A + B1 responded negatively linear to periods of storage evaluated in both cutting heights. The contents of the carbohydrate fraction B2 and proteins A and C exhibited a positive linear response to storage time for a cutting height of 0.04 m and a quadratic effect for hay cutting height at 0.08 m above soil level, with an opposite behavior for both cutting heights for the B1 protein levels and C carbohydrate fraction. The B2 fraction showed a negative linear response as a function of storage time, with a reduction in the fraction of 0.09 and 0.11 percentage units for each day of storage, for hay cutting height of 0.04 and 0.08 m, respectively. The B3 fraction responded quadratically to the storage time, the two studied cutting heights. The storage of Tifton 85 hay cut at 0.04 m above soil level for 120 days leads to a decrease in fractions of rapid ruminal degradation and increase of the indigestible fraction in carbohydrate and protein fractions. Based on the results obtained it is recommended the cutting of the Tifton 85 bermuda grass forage to produce hay at 0.08 m and its storage up to 30 days provided that under ideal conditions.
