Características morfométricas, rendimentos no processamento e composição centesimal da carne do barbado

This study was carried out to evaluate the morphometric characteristics, the yield and the centesimal composition of different cuts of the Barbado's (Pinirampus pirinampu) flesh, captured in the Itaipu Reservoir. Were used 55 animals randomly distributed into three classes of body weight [less than 620 g (n = 15), between 620 and 1.120 g (n = 16) and greater than de 1.120 g (n = 24)]. Were measured the standard length (SL), the total length (TL), the head length (HL), the head height (HH), the trunk length (TRL), the trunk height (TH) and width of the trunk (WT). Then were established the morphometric relationships: (HL/SL), (HL/HH), (SL/TL), (WT/TRL), (WT/TH) (TH/TRL). Afterwards were measured the flesh's cut yield and the residue waste yield called: trunk (TC), fillet (FILLET), abdominal fillet (AF), head (HEAD), viscera (VISC), fin, spine and skin (SKSF). The levels of moisture, ash, fat and crude protein from FILLET and AF were determined. The body weight affected (P<0.05) the WT/TRL, WT/TH, TH/TRL, TR, FILLET, HEAD and SKSF, however didn't affected the centesimal parameters. In conclusion, the Barbado (Pinirampus pirinampu) has allometric growth and the flesh processing from fishes with more than 620 g provides better yields of edible parts. In addition, the chemical composition of meat suggests its potential for use in the manufacture of artisanal or industrial products.

Características morfométricas e rendimento corporal do suruvi Steindachneridion scriptum agrupados por sexo

The body shape, body yields and morphometric ratios is important for species characterization and evaluation of their productive potential. The aim of this study was to determine the morphometric reasons, the body yields and correlations for male and female suruvi, Steindachneridion scriptum. Was analyzed 30 males and 30 females, and length and weight measurements were made. Was calculated carcass yields and morphometric relationships. The design was complete randomized. Data were subjected to analysis of normality; variance and means were compared by t test and Mann Whitney test. The average total weight of males was 1,583.50 +/- 263.79 g, while the total weight of females was 1,606.66 +/- 185.34 g. The total lengths were 53.42 +/- 2.64 cm for males and 53.35 +/- 1.98 cm for females. Average total weight and total lengths was similar between the sexes (P>0.05). Dress out yields of 65.54 +/- 1.36% (males) and 65.71 +/- 1.20% (females) and edible portions of 41.99 +/- 1.66% (males) and 41.93 +/- 2.05% (females) did not differ significantly between the sexes (P>0.05). The percentage of head relative to the total weight was significantly higher in males (17.67 +/- 1.24%) than in females (16.90 +/- 0.85%). The weight of the viscera such as the percentage relative to the total weight was significantly higher in females. The species has no body yields and morphometric characteristics limitations for commercial production.

Geoprocessamento de variáveis morfométricas para caracterização da microbacia do Córrego do Petiço

This study aims to perform the morphometric characterization of the watershed stream Petiço, Botucatu-SP, through techniques of GIS by GIS IDRISI Selva and Charter planialtimetric Botucatu (SF-22-ZB-VI-3) , edited by IBGE (1969), scale 1: 50000 for ranking the drainage network and the morphometric analysis. The variables analyzed were the dimensions, the relief pattern, pattern of the drainage network and the shape variables. The results show that related to how the watershed has an oblong shape with environmental interpretation with low tendency to flooding and erosion. The sinuosity index of 1.22 shows that the channels of the micro tend to be somewhat sinuous, which allows to infer that is permeable soil with good water infiltration. Based on the results of the morphometric variables was found that the watershed is in good condition of conservation, however, presents certain risks of susceptibility to erosion, and environmental degradation in some points, being fundamental to the maintenance of vegetation cover, in view of the roughness coefficient (Rn). Thus, the evaluation of morphometric characteristics in the study watershed constitutes an important tool in conjunction with the use of GIS and Geographic Information Systems makes possible the planning and management of natural resources aimed at their conservation.

Effect of sequence of insemination after simultaneous thawing of multiple semen straws on conception rate to timed AI in suckled multiparous Nelore cows

The objective was to determine the effect of sequence of insemination after simultaneous thawing of multiple 0.5 mL semen straws on conception rate in suckled multiparous Nelore cows. The effect of this thawing procedure on in vitro sperm characteristics was also evaluated. All cows (N = 944) received the same timed AI protocol. Ten straws (0.5 mL) of frozen semen from the same batch were simultaneously thawed at 36 degrees C, for a minimum of 30 sec. One straw per cow was used for timed AI. Frozen semen from three Angus bulls was used. Timed AI records included sequence of insemination (first to tenth) and time of semen removal from thawing bath. For laboratory analyses, the same semen batches used in the field experiment were evaluated. Ten frozen straws from the same batch were thawed simultaneously in a thawing unit identical to that used in the field experiment. The following sperm characteristics were analyzed: sperm motility parameters, sperm thermal resistance, plasma and acrosomal membrane integrity, lipid peroxidation, chromatin structure, and sperm morphometry. Based on logistic regression, there were no significant effects of breeding group, body condition score, AI technician, and sire on conception rate, but there was an interaction between sire and straw group (P = 0.002). Semen from only one bull had decreased (P < 0.05) field fertility for the group of straws associated with the longest interval from thawing to AI. However, the results of the laboratory experiment were unable to explain the findings of the field experiment. Sperm width:length ratio of morphometric analysis was the single sperm characteristic with a significant interaction between sire and straw group (P = 0.02). It was concluded that sequence of insemination after simultaneous thawing of 10 semen straws can differently affect conception rates at timed AI, depending on the sire used. Nevertheless, the effects of this thawing environment on in vitro sperm characteristics, remain to be further investigated. (C) 2012 Elsevier Inc. All rights reserved.

Capacità di sviluppo di Diabrotica virgifera virgifera Leconte su ospiti alternativi al mais

Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae) è una specie esotica invasiva di origine centro americana e introdotta in Europa agli inizi degli anni ’90, in Italia nel 1998. Considerata negli Stati Uniti la principale avversità del mais (Zea mais L.), è oggi presente in quasi tutti i Paesi europei dove è presente tale coltura. Poiché il mais risulta l’ospite prioritario di Diabrotica, attualmente il principale metodo di contenimento consiste nella rotazione con una coltura non ospite. L’obiettivo del lavoro è stato quello di indagare sulle piante ospiti alternative al mais nel nostro ambiente, accertando il ruolo che possono avere le infestanti o altre Poaceae coltivate nella biologia della Diabrotica. Tali essenze sono state scelte tra specie mai sottoposte a sperimentazione e tra quelli già oggetto di indagini, ma su cui si sono ottenuti esiti discordi o non soddisfacenti. Sono state allestite prove con infestazione artificiale in ambiente controllato e prove in campo per valutare la sopravvivenza larvale e il completamento del ciclo, nonché le prestazioni biologiche degli individui ottenuti. Le ricerche hanno permesso di osservare sopravvivenza di Diabrotica su numerose graminacee, in particolare cereali. Tale capacità è confermata dalla presenza di larve di diversa età e in alcuni casi di pupe sulle specie ospiti alternative, sia con infestazione artificiale che in campo. Tuttavia crescita e sviluppo su queste piante sono stati più lenti del mais e gli stadi giovanili trovati hanno mostrato caratteristiche morfometriche inferiori rispetto a quelli del mais. Adulti non sono mai stati raccolti in campo, mentre questo si è verificato in condizioni controllate. Le specie che meritano maggior attenzione sono i cereali Triticum spelta e Panicum miliaceum e l’infestante Sorghum halepense. Si potrebbe dunque ipotizzare che alcune specie vegetali possano fungere da ospite secondario quando non è presente il mais riducendo l’efficacia dell’avvicendamento.
