Grasslands in warm‐climate regions are often based on grass monocultures, increasing their dependence N fertilizers. Integrating perennial legumes into pastures is a logical option. The objective of this 2‐yr study was to assess seven rhizoma peanut ( Arachis glabrata Benth) cultivars: Arbrook, Arblick, Ecoturf, Florigraze, Latitude 34, UF Peace, and Tito. Above‐ belowground responses included biomass, vitro organic matter disappearance (IVOMD), concentration, content, δ 15 N, proportion...
Abstract The study evaluated forage and livestock performance in different grazing systems over two years. Treatments were three contrasting systems: (I) N-fertilized bahiagrass ( Paspalum notatum Flüggé) the summer overseeded during winter by ryegrass Lolium multiflorum ) oat Avena sativa L.) (Grass + N); (II) unfertilized with a blend of clovers Trifolium spp.) Clover); (III) rhizoma peanut (RP; Arachis glabrata Benth.) mixture summer, Clover RP). Average daily gain (ADG), per area (GPA),...
The aim of this study was to evaluate the effect replacing tifton hay (Cynodon spp.) with alfalfa (Medicago sativa) in spineless cactus-based (Nopalea cochenillifera Salm-Dyck) diets for lactating goats on intake and digestibility nutrients, ingestive behavior, metabolic profile production composition milk. experimental were composed increasing levels (0, 33, 67 100% dry matter (DM)) replace hay. Twelve crossbred multiparous Saanen an average initial body weight (BW) 46.2 ± 7.5 kg milk 3.0...
Sheep production systems installed in the semi-arid region of Brazil depend on forage support 'caatinga' biome.This study aimed at evaluating substitution hybrid 'Tifton 85' (Cynodon spp.) by cassava (Manihot pseudoglaziovii Pax & K. Hoffm.)hay or silage components sheep's' body weight.Twenty-four animals, with no defined breed, were used for study, an initial weight 19.77 ± 1.95 kg and average age 6-mo, being divided into three treatments ('Tifton hay, silage, hay).The animals slaughtered...
Weed encroachment on grasslands can negatively affect herbage allowance and animal behavior, impacting livestock production. We used low-cost GPS collars fitted to twenty-four Angus crossbred steers evaluate the effects of different levels weed activities spatial distribution. The experiment was established with a randomized complete block design, three treatments four blocks. were paddocks free weeds (weed-free), in alternated strips (weed-strips), spread throughout entire area...
the high volume of mangos harvested during season, associated with inappropriate management fruit after harvesting results in increased waste this valuable resource. Mango fruit, rich carbohydrates, has potential use animal feeding. Objective: to evaluate effect replacing corn whole mango meal (0, 330, 660, and 1000 g/Kg on dry matter basis) diets dairy goats rumen fermentation kinetics, intake, milk yield composition, economic results. Methods: eight lactating Saanen crossbred (48.7 ± 1.99...
This study aimed to evaluate intake, digestibility, and performance in sheep fed increasing levels of annatto byproduct (AB). A total 32 male without defined breed were used. Their initial weight was 23.17±1.45 kg. The animals housed individual pens offered feed twice a day. Nutrient intake quantified by the difference between fractions present remains. apparent digestibility estimated with aid external marker LIPE®. Weight gain measured final animals. dry matter (DM; g/day; g/kg BW;...
Abstract Grazing cool-season cover crops provides a sustainable way of extending the grazing season and reducing impact row-crop farming systems on environment. Cover promote soil health; however, impacts health in Southeast are not well understood. The objective current study was to determine effects different crop mixtures cotton (Gossypium hirsutum)-peanut (Arachis hypogaea) cropping system. experiment consisted 18 paddocks, planted grass [‘Coker’ oat (Avena sativa)], + legume [‘Dixie’...
Abstract Since the discovery of plant growth-promoting rhizobacteria (PGPR) in mid-20th century, efforts have focused on utilizing them to reduce synthetic fertilizer usage and improve sustainability agricultural systems. However, research forage systems is lacking. The objective current study was determine use PGPR bermudagrass (Cynodon dactylon) Central Alabama. designed as a split plot conducted at E.V. Smith Research Extension Center (Shorter, AL) compared four levels five nitrogen...

SUMMARY The work was conducted to evaluate the metabolic profile of lactating goats fed diets containing integral mango meal as a replacement for corn. Four levels (0, 33, 66 and 100%) were evaluated in with forage:concentrate ratio 60:40. Eight crossbred multiparous Saanen (48.72 ± 1.99 kg BW) introduced experiment 48 days postpartum maintained up 124 lactation. It used double Latin Square (4x4) experimental design, four treatments, periods animals per square. There no effects (P>0.05)...
Este trabalho teve como objetivo avaliar as medidas morfometricas das carcacas de cordeiros submetidos a diferentes niveis palma forrageira. Foram utilizados 32 machos, com peso medio inicial 20,4 kg. Os animais foram abatidos apos 57 dias confinamento. formuladas quatro dietas inclusao Palma Miuda (Nopallea cochenillifera Salm Dyck) 0; 25; 50 e 75% em substituicao ao feno tifton-85 (Cynodon dactylon). O delineamento experimental utilizado foi blocos casualizados. da carcaca fria, indice...
An experiment was conducted to evaluate the effects of increasing levels spineless cactus (0%, 33%, 66%, and 100%) used as a substitute for wheat bran in buffalo diets on quantitative qualitative traits meat carcass.Twenty Murrah buffaloes at 18 months age, with mean initial weight 292.9±57.3 kg, were randomly allocated four treatments five replicates. The animals slaughtered after 90 days feedlot. replacement diet carcass traits, slaughter weight, yield measurements studied.Increased led...
Stable isotopes are an important tool to assess livestock diet in binary mixtures of C3-C4 forages. However, the use stable trace using tropical arboreal legumes has been limited. The objective this study was evaluate 13C identify proportions grass (C4) and legume sheep diet, when consuming various inclusion levels. We evaluated models correlating faecal δ13C inferred which model can better predict different or consumed by sheep. Thirty male lambs (17 ± 1.3 kg) were used, experiment set up a...
