Forty-four feedlot-finished Nellore cattle were used to evaluate the impacts of temperament on performance, meat and carcass traits, serum concentrations hormones, proteins, enzymes, immunoglobulins. Individual was assessed at feedlot entry (d 0), 67 d, 109 utilizing chute score (CS; 5-point scale) exit velocity (EV). Temperament scores calculated averaging CS EV scores, subsequently classified according their (an average ≤3 = adequate [ADQ], or an >3 excitable [EXC]). At end experiment...
Agricultural management systems are needed to simultaneously enhance production, and improve soil quality. We investigated the effects of intercropped grass on production corn ( Zea mays L.) harvested for silage at 0.20 0.45 m height in summer, as well subsequent forage, soybean [ Glycine max (L.) Merr.], responses a Typic Haplorthox Botucatu, SP, Brazil. Palisade Urochloa brizantha (Hochst. ex A. Rich.) R. Webster ‘Marandu’] was introduced companion crop with (Years 1 2), while signal...
Intercropping sorghum [ Sorghum bicolor (L.) Moench] with tropical perennial grasses and using the appropriate rate of sidedress N application can maximize grain yield (GY) revenue improve land‐use efficiency (LUE). The effects monocropped (MS) or intercropped palisadegrass ( Urochloa brizantha cv. Marandu; SPG) guineagrass Panicum maximum Mombaça; SGG) rates 0, 50, 100, 200 kg ha −1 on leaf nutrient concentration, GY, revenue, LUE were investigated during three growing seasons at Botucatu,...
The aim of this study was to evaluate the effect two nutritional statuses on productive performance Dorper lambs naturally infected with gastrointestinal nematodes. Thirty-two lambs, grazing together same pasture, were allocated into four experimental groups: (G1) infected-supplemented diet, (G2) control-supplemented (G3) infected-basal and (G4) control-basal diet. Control animals received suppressive treatment monepantel every weeks, while precautionary anthelmintic treatments given all...
SUMMARY The adequate management of soil acidity has long been a challenge in no-till (NT) cropping systems. Some studies conducted sub-tropical conditions have demonstrated the feasibility surface liming. However, for tropical regions with dry winters, little long-term information about rates and frequencies application is available. A 12-year field trial was performed under no-tillage system an annual crop rotation scheme. treatments were composed four lime (0, 1000, 2000 4000 kg/ha),...
Intercropping grain with forage crops bridges the gap between agriculture and sustainability. In tropical regions, grasses are increasingly being adopted as winter pasture intercropped in rotation maize to maximize food production. However, current recommendations for nitrogen (N) fertilizer application based on monocropped ( Zea mays ), best N management approach intercropping systems remains unclear. A field experiment was carried out three growing seasons [monoculture maize, palisadegrass...
This study was conducted to determine optimum test duration for measuring performance, feed intake and efficiency. Sixty young Nellore bulls were submitted feeding performance fed in individual pens over 112 days. Body weight determined every 28 days, after fasting of water 16 hours. Changes variance, relative variance Pearson Spearman correlations among data from shortened periods (28, 56 84 days) full period (112 used duration. Test average daily gain, dry matter intake, feed:gain ratio...
In the context of sustainable tropical agriculture, an innovative corn ( Zea mays L.) to silage-grass-legume intercropping system can promotes plant diversity, improves agronomic performance and land-use efficiency, increases yield oversown black oat Avena strigosa Schreb) soybean [ Glycine max (L.) Merr.] silage in succession. Thus, during three growing seasons on a Typic Haplorthox Botucatu, São Paulo State, Brazil, four treatments production were implemented summer/autumn with...
Abstract The effect of four diets on the performance Dorper lambs that were artificially mix-infected with 1000 infective larvae (L3) Haemonchus contortus and L3 Trichostrongylus colubriformis every three days for 12 weeks was evaluated. For each diet, one infected group (n = 7) control 4) set up. contained following proportions hay (H) concentrate (C): Diet 1 - 100%H; 2 75%H:25%C; 3 50%H:50%C; 4 25%H:75. All groups showed decreases in mean packed cell volume (PCV) total plasma protein,...
Abstract: The objective of this work was to evaluate the effect intercropping systems between corn and tropical forages, at different cutting heights, on silage production, light interception, land use efficiency, competition factors, pasture production. In 2010/2011 2011/2012 crop seasons, two cultivation modalities were evaluated in summer/autumn - monocropped with residual regrowth signal grass (Urochloa decumbens) from soil seed bank intercropped palisade (U. brizantha 'Marandu') -, a...
The objective of this study was to evaluate the correlated responses selection for growth in feed efficiency and carcass traits Nellore animals. A total 121 animals control (NeC) herds were subjected performance testing classified regarding residual intake (RFI). Sixty-seven these selected finished until reaching 4 mm subcutaneous fat thickness between 12th 13th ribs. slaughtered at a mean age 541 days live weight 423 kg NeS 363 NeC, measured. Animals presented higher initial slaughter...
The objective of this study was to evaluate the yield and nutritional value silage made from corn intercropped with marandu palisadegrass (Urochloa brizantha cv. Marandu) in an integrated crop-livestock system. harvested at different maturity stages cutting heights processed or not before ensiling. experimental design a randomized block four replications 2x2x2+1 factorial scheme. treatments were composed two (20 45 cm) (1/4 kernel milk line physiological maturity) subjected methods...
