Forage cactus pear is considered a xerophilic plant, so it adapted to harsh semiarid conditions and forage resource of significant importance for animal production in regions that are subject food shortage long dry periods. We aimed evaluate the morphometric physiologic characteristics water-use efficiency ‘Gigante’ under different settings irrigation depth intervals with saline water. The treatments included seven water application: rainfed, 5 liters per linear meter every 15 days; 7%...
Abstract. The objective of this study was to evaluate the effects including soybean oil (SO) in diet feedlot lambs on metabolic, behavioral, and ruminal parameters. Five rumen-cannulated (average body weight 47.76 ± 7.14 kg at approximately 15 months age) were distributed a 5 × Latin square design. Their diets consisted increasing levels SO inclusion: 0, 30, 60, 90, 120 g kg−1 dry matter (DM). Each period lasted 21 d, with 14 d for adaptation 7 data collection. The analyzed...
This study evaluated the effects of gliricidia hay inclusion in total mixed rations made from giant forage cactus on fermentative profile, losses, chemical composition, and aerobic stability. The completely randomized design was adopted with five treatments (0, 5, 10, 15, 20% a natural matter-NM basis) replications. Dry matter, ether extract, crude protein exhibited quadratic maximum peaks at 9.33%, 4.94%, 15.38%. Linear increases were observed neutral acid detergent fiber hemicellulose,...
Understanding of the morphogenetic characteristics allows comprehension aspects related to form and function forage plants, providing opportunities identify potentially high productive plants distinct defoliation management requirements. The objective this experiment was carry out a comparative study ten tropical grasses using structural variables. Treatments corresponded Panicum genus (P. maximum cultivars Tanzânia Mombaça) Brachiaria (B. brizantha Piatã, Marandu, Xaraés, Capiporã Arapoty;...
Grazing management strategies affect not only herbage accumulation but also the efficiency of grazing. This study aimed to evaluate (leaf, stem and dead material), grazing losses mulato grass (a Brachiaria ruziziensis × brizantha cv. Marandu hybrid) subjected rotational stocking management. Treatments consisted combinations between two post-grazing heights (15 20 cm) pre-grazing conditions (95 % maximum canopy light interception (LI)) assigned experimental units (1200-m² paddocks) according...
The objective of this work was to evaluate the morphogenetic and structural characteristics xaraes palisadegrass submitted three cutting heights (15, 20 25 cm) when sward reached 95% light interception during regrowth. experiment carried out according a complete randomized block design with replications. surface height under condition very homogeneous values around 30 cm. increase in reduced leaf elongation rate number live leaves but increased stem rate. As criterion same, before intense...
This work was performed aiming to evaluate the morphogenetic and structural characteristics of Andropogon gayanus cv. Planaltina species submitted three cutting heights (20, 27 34 cm). The were allocated in experimental units (12 m²) a complete randomized block design with replications. cuts done when light interception by sward reached 95%. At this moment, height revealed itself constant values close 50 cm. lowest (20 cm) influenced negatively final leaf blade length, number live leaves,...
This study aimed to evaluate the effect of inclusion protected or unprotected fats in diet feedlot lambs on feeding behavior, productive characteristics, carcass traits, and meat quality. Forty male Dorper × Santa Inês (22.27 ± 2.79 kg) were randomly assigned treatments a completely randomized design. The experimental consisted five diets: no added fat (NAF), whole soybeans (WSB), calcium salts fatty acids (CSFA), soybean oil (SO), corn germ (CG). total intake dry matter (DMI) (p < 0.001)...
SUMMARY Plants’ ability to rebuild their tiller population is affected by weather changes and management strategies. The hypothesis of the present study was that frequency severity defoliation alter Mulato grass ( Brachiaria ruziziensis × brizantha cv. Marandu) sward development, proportion aerial basal tillers, interfering with stability. objective evaluate aerial, total density in tillering dynamics. Treatments corresponded strategies rotational grazing characterized combinations between...
An experiment was carried out with the objective to evaluate growth pattern of tropical forage grass under free by using morphogenetic and structural characteristics expectation this study for evaluation protocol. The experimental area established two cultivars Panicum maximum Jacq. (Mombaca Aruana), a hybrid cultivar P. Infestum BRA-7102 (Massai), Brachiaria brizantha (A. Rich.) Stapf (Marandu Xaraes) Molasses (Melinis minutiflora Beauv.) jaragua (Hyparrhenia rufa (Nees) Stapf.). grasses...
Foram avaliadas as características morfogênicas e estruturais de gramíneas forrageiras com o objetivo agrupá-las, acordo seu padrão desenvolvimento, em seus respectivos grupos funcionais. As foram plantadas parcelas 1,0 m² 24 plantas, delineamento blocos completos casualizados três repetições. Os dados submetidos à análise fatores, reduzindo variáveis quatro fatores: desenvolvimento massa, mortalidade perfilhos, estádio longevidade foliar. agrupamento por otimização Tocher adotando-se a...
The pasture structure is the point of origin and convergence plants grazing animal responses, which makes its knowledge essential in planning management strategies.The objective this study was to evaluate describe variation sward mulato grass subjected stocking treatments corresponded combinations between postgrazing height (15 20 cm) pre-grazing targets (95% maximum light interception during regrowth: LI 95% Max ).Sward height, interception, forage mass, morphological composition, vertical...
We assessed the accumulation dynamics of forage and its components in Elephant grass cv. Napier (Pennisetum purpureum Schum.) that were subjected to three post-grazing height treatments (30, 50, 70 cm) from February through May 2009 (experiment one) December 2010 two). In experiment one, grazing events started when light interception by canopy reached 95%. The same was adopted for two, except first event, which based on apical meristems basal tillers. experimental design both experiments a...
Context Goat farming is an important socio-economic activity. The feedlot system allows the finishing of animals in short periods through use concentrated diets; however, these diets increase system’s production costs. Palm kernel cake (PKC) has proved to be a good alternative feed source for cattle and sheep because its nutritional characteristics potential reduce Aim This experiment aimed evaluate effect high-concentrate with inclusion PKC on carcass traits meat quality goat kids. Methods...
The objective of the current study was to evaluate effects soybean oil inclusion in diets on feeding behaviour, digestibility, performance, and blood metabolites feedlot lambs. Forty non-castrated Santa Inês lambs with a mean age 5 months initial body weight 34.88 ± 3.19 kg were used 40-day trial. distributed five experimental increasing (SO) levels: 0, 30, 60, 90, 120 g/kg DM. SO promoted linear reduction DM intake (
This experiment was conducted to estimate the effects of nitrogen fertilization associated with initial height Piata palisade grass on number and structural characteristics individual tillers after deferment period. An area Brachiaria brizantha cv. measuring approximately 288 m² used. Combinations levels (0, 75 150 kg/ha nitrogen) heights sward (low - 20 cm, medium 30 cm high 40 cm) were evaluated. The experimental design completely randomized blocks in subdivided plots three replications....
