1. Glucose and insulin curve in pregnant mares and its relationship with clinical and biometric features of newborn foals
RESUMO: O objetivo do presente estudo foi descrever a dinâmica das curvas de glicose e insulina em éguas gestantes e avaliar as curvas de acordo com o escore de condição corporal, identificando a presença de resistência insulínica e correlacionando esses valores com o peso, altura e alterações clínicas dos neonatos. Para isso, as éguas prenhes for

4. X-ray microtomography in comparison to radiographic analysis of mechanically damaged maize seeds and its effect on seed germination
ABSTRACT. Among the most relevant aspects of seed production, mechanical damage may affect seed germination and reduce health and vigor. This study introduces a noninvasive high-resolution imaging procedure for evaluating the mechanical damage to maize seeds and the effects on seed germination. Seeds with different levels of mechanical damage were evaluated

5. Oxidative Damage and Antioxidant Response in Chenopodium murale L. Exposed to Elevated Levels of Zn
ABSTRACT Present study was carried out to investigate the effects of different Zn concentrations on growth and some antioxidant responses in Chenopodium murale L. The seeds were sown on the pots. 45-day plants were transferred to hydroponic solution containing 0.2 (control), 150, 300 and 600 µM Zn. The plants were harvested at 6 days after applying Zn treat

6. SUNFLOWER EMERGENCE AND INITIAL GROWTH IN SOIL WITH WATER EXCESS
ABSTRACT: Sunflower crops are grown in different regions worldwide. However, the stress caused by water excess in the soil impairs this crop growth and yield. The aim of the present study was to determine the response of sunflower plants to long periods of water excess during initial development stages. Water excess treatments were applied at the initial dev

7. Metabolic, productive and reproductive responses to postpartum short-term supplementation in primiparous beef cows
The objective of this study was to evaluate the effect of a short-term supplementation with rice bran (2 kg/cows/day) on the endocrine and metabolic profiles and hepatic gene expression, associated with the reproductive response in beef cows in grazing conditions. Thirty-eight primiparous beef cows (Hereford, Angus and Hereford × Angus) were used in a rando

8. Biomass flow in massai grass fertilized with nitrogen under intermittent stocking grazing with sheep
This study evaluated the biomass flow of massai grass in regrowth subjected to different nitrogen levels (control - no fertilization; 400; 800; and 1200 N kg ha-1year-1) and under rotational stocking with sheep, in a completely randomized design with repeated measures over time. The leaf elongation rate increased with increasing nitrogen levels (N) and the f

9. Efeitos do exercício físico sobre as propriedades morfológicas e mecânicas de miócitos cardíacos de ratos diabéticos / Effects of exercise on the morphological and mechanical properties of cardiac myocytes from diabetic rats
The aim of this study was to verify the effects of a swimming training (ST) on the morphological and mechanical properties of cardiac myocytes from different regions of the left ventricle (LV) of rats with experimental diabetes. One month old male Wistar rats (body mass ~ 250g) received an intraperitoneal injection of Streptozootocin (STZ, 60mg/kg body mass)

10. Desempenho agronômico de cultivares de soja em diferentes épocas de semeadura no cerrado do Distrito Federal
In the Brazilian Savannahs, as a general breeding procedure, cultivars, progenies and other soybean genotypes are grown under ample environmental conditions, before they are released to cultivation. The variations comprise different soil types, fertility levels, moisture regime, sowing dates, temperature and cultivation patterns. An outstanding cultivar in o

11. Reproductive behavior and sex pheromone identification of Pseudaletia sequax (Lepidoptera: Noctuidae) / Comportamento reprodutivo e identificação de feromônio sexual de Pseudaletia sequax (Lepidoptera: Noctuidae)
The effects of pupal period and age on calling behavior of virgin females of Pseudaletia sequax were determined. Larvae were reared on artificial diet. Calling behavior of groups of females of similar age of pupation was observed every 10 minutes for six days at reversed photoperiod. Females were considered calling when they had assumed a characteristic posi

12. Morphophysiological characteristics and herbage accumulation in mombaça grass subjected to defoliation regimes / Características morfofisiológicas e acúmulo de forragem em capim-mombaça submetido a regimes de desfolhação
Grazing systems that take into account the rhythm of regrowth of forage plants after defoliations can optimise herbage accumulation and ensure the control of sward structure. In these context, the objective was to evaluate patterns of response of Panicum maximum cv. Mombaça to defoliation in two experiments using measurements of sward morphogenetic and stru
