Características morfogênicas e estruturais de híbridos de sorgo submetidos a adubação nitrogenada

The effect of two topdressing nitrogen doses was evaluated on the morphogenetic and structural characteristics of sorghum hybrids (Sorghum bicolor (L.) Moench) BRS 801 and 0734006, cultivated in vases in open-air conditions. A completely randomized design was used with four treatments arranged in factorial outline 2x2 (two sorghum hybrids and two nitrogen doses, 50 and 100 kg ha-1), with eight replications per treatment. There was a significant effect of interaction hybrid x fertilization on the leaf appearance rate, the hybrid BRS 801 being more responsive to the increased nitrogen dose. The phyllochron, the total number of leaves and leaf elongation rate, were influenced both by nitrogen doses and by hybrids. The leaf senescence rate was not influenced by factors fertilization and hybrids. These variations in morphogenetic and structural characteristics between the hybrids and/or nitrogen doses, probably indicate that hybrids respond in a different way to topdressing.

Glicemia, proteinograma e perfil de alguns componentes bioquímicos séricos de cabritos da raça bôer

The newborn goat kids suffer several adjustments to life outside the uterus that affect different body functions that they need to produce heat, muscle activity and start searching for food. All these events lead to changes in several blood constituents such as proteins and serum biochemical parameters. Other studies have shown these variations, but not extend beyond the neonatal period to phase in young animals. The aim was to test the hypothesis that there is variation of the protein profile, and biochemical components of blood glucose in goat kids from birth to 75 days of life in terms of adaptation to extra uterine life. To achieve these objectives have been collected blood samples from 25 goats born by normal delivery, regardless of their sex. The variables serum total protein (TP), albumin, α-globulin, β-globulin, γ-globulin, which includes the immunoglobulin G (IgG), aspartate (AST), alkaline phosphatase (ALP), gamma-glutamyltransferase (GGT), creatinine and urea, and glucose were determined at times zero (immediately after birth), two, seven, 15, 30 and 75 days old. We observed significant differences in all variables between times, but only the creatinine concentration was higher than those of other moments in time zero and two days old, probably due to immaturity of renal function in newborn animals. The blood constituents of the kids had variations in the study period, related to physiological and nutritional causes.

Glicemia, proteinograma e perfil de alguns componentes bioquímicos séricos de cabras da raça bôer no pós-parto

The objective was to test the hypothesis that there is variation of some protein components, biochemical and glucose from the blood of goats in the postpartum period. ElevenBoer goats were used to evaluate the serum following variables: total protein (TP), albumin, α-globulin, β-globulin, γ-globulin, immunoglobulin G (IgG), aspartate (AST), alkaline phosphatase (ALP), gamma-glutamyltransferase (GGT), creatinine, urea and glucose. These components were determined in moments zero (immediately after delivery), two, seven, 15, 30 and 75 days postpartum. The β-globulin, IgG, creatinine and urea from the goats did not show significant variations, the blood glucose at time zero was greater than the baseline values due to physiological stimulation of glycogenesis determined by the increase of cortisol in delivery. The blood constituents of goats showed variations in the period to 75 days postpartum as a result physiological causes related to delivery and postpartum.
