“…It is clear that the grain fraction has a great influence on the quality of silage (Neumann, Restle, & Brondani, 2010), however, the vegetative fraction is responsible for more than half of the silage composition, indicating that this fractions needs to be taken into account. No difference was observed between hybrids for the other components at harvest time (Table 4).…”

he objective of this study was to evaluate the production and physical composition of three maize hybrids (Zea mays, L.) for silage production at six maturity stages. The hybrids evaluated were Maximus VIP3, Defender VIP and Feroz VIP. The experiment was conducted in a completely randomized block design with four replicates. The mean plant heights observed at harvest time (2.33 m, 2.45 m and 2.40 m) demonstrated that all materials were medium-sized hybrids. A positive correlation was observed between plant height and height of the ear insertion, varying from 0.86 for the Feroz VIP hybrid to 0.88 for the Maximus VIP3 hybrid, but these two variants had no correlation with the productivity data. There was a significant difference for the production of fresh biomass at the R1, R2 and R5 stages, with Maximus VIP3 obtaining the highest yields. The proportion of grains in the physical composition of plant varied between hybrids, where Maximus VIP3 and Defender VIP (482.2 and 461.7 g kg-1, respectively) were superior to Feroz VIP (429.7 g kg-1). With the advancement of maturity, there was a decreasing linear behavior for stem and leaf participation, with reductions of 3.8 g kg-1 and 4.5 g kg-1, respectively, per day (R2 = 0.79 and 0.80, respectively), quadratic behavior for bracts and corncob and a linear increase in grain participation in the plant structure, with an increase of 7.7 g kg-1 per day (R2 = 0.88). In general, the three hybrids present good characteristics for silage production and permit harvesting in the hard grain stage, allowing the addition of starch in relation to the farinaceous grain stage.

“…It is also considered a great source of digestible fiber with 42 to 55% neutral detergent fiber, due to the removal of starches and sugars during the process, leaving mainly the structural cell wall carbohydrates, such as cellulose and hemicellulose (Meneghetti and Domingues, 2008). Centrifuged soybean meal is a byproduct of soybean meal, obtained by chemical processes, in which an important fraction of the protein is extracted for making food products for human consumption, constituting an alternative for the replacement of soybean meal in cattle diets, with average values of 33% CP and 71% of total digestible nutrients (Neumann et al, 2006). Farms that offered WBG also offered corn silage and commercial concentrate (Figure 1, Table 4).…”

Animal production systems and agribusinessFull-length research article Use of quali-quantitative feeding practices criteria in typology of smallholders' dairy production systems ABSTRACT -This study aimed to typify smallholders' dairy systems using qualiquantitative measures of feeding practices and detect the main discriminatory elements identifying the systems. We collected data from 30 farms distributed in 10 municipalities in the eastern region of Rio Grande do Sul, Brazil, using a survey with semi-structured questions, in addition to bimonthly observations of milking and feeding practices. Multivariate analysis based on principal factors and cluster analysis were performed. Multiple linear regressions were made between the principal factors scores and variables of milk production and composition. Three principal factors with eigenvalues ≥1.0 explained 58.9% of the total variance. The original variables with the highest factor loading values were production scale and feeding practices involving greater quantities of byproducts; use of corn silage and sugarcane; and commercial and farm-made concentrate for principal factor 1, principal factor 2, and principal factor 3, respectively. Milk yield and concentrations of lactose and solids non-fat increased linearly with principal factor 1 and principal factor 3 but decreased linearly with principal factor 2. Observations were grouped into three clusters. Farm area and quantity of corn silage and byproducts were the most important variables to set the clusters. The use of quali-quantitative feeding practices criteria to characterize dairy systems is effective to identify the opportunities for improving milk production and composition. Whereas high inclusion of sugarcane as roughage was detrimental for milk production, moderate supply of concentrate and byproducts enhanced milk yield without compromising milk composition.

“…Os animais que receberam o teosinto tiveram maior ganho de peso, porém, sem diferença estatística do capim-elefante, ambos com maiores porcentagem de Estrato Etéreo, porém o teosinto possui menos proteína bruta em sua composição. No presente trabalho a utilização de capim-tifton apresentou resultados superiores por sua composição elava em Fibras e pelo ensilamento que aumenta a disponibilidade de nutrientes (NEUMANN et al, 2004).…”

“…A pronta disponibilidade das forragens, na forma de silagem, adquire importância estratégica, uma vez que possibilita a comercialização de animais nos períodos economicamente mais favoráveis, pois se apresenta como uma fonte alternativa de nutrientes. Quando armazenado e utilizado de forma adequada, os ensilados permitem o planejamento da produção em ganho de peso, com base em um material de composição química conhecida, que permite a confecção de dietas nutricionalmente equilibradas (NEUMANN et al, 2004).…”

The objective of this study was evaluated the effect of different tropical forages in the feeding of juvenile grass carp, the treatments were: elephant grass (Pennisetum purpureum); coloniao grass (Panicum maximum); tifton grass (Cynodon dactylon) and Brachiaria sp, being the first three ensilad and the last in natura. All the experimental treatments were supplemented with an experimental pelletized ration with 30% CP and 3000 kcal/ digestively energy /kg in the proportion of 10% of the alive weight. Significant difference was not observed in the chemical composition of forages appraised. There was no difference (P>0,05) of the weight gain in the juveniles fed with Brachiaria sp., coloniao or elephant grass. However, the silage of tifton grass provided (P <0,05) larger weight earnings. The results demonstrate the good potential of tifton grass in the grass use in feed-grass cover, it provides higher weight gain.
