| Cette étude, réalisée dans la partie Nord-Est du lac de Bizerte du premier Avril au 30 Juin 1999, porte sur l’étude de l’effet des deux paramètres, distance entre les touffes et poids initial des touffes, sur le rendement de culture par bouturage de Gracilaria verrucosa selon le mode des boudins de sable. Il en ressort que les conditions optimales de culture de cette espèce sont engendrées par un poids initial de 200 g, une distance entre les fragments de thalles de 30 cm et une récolte impérativement vers la fin du mois de Juin. Dans ces conditions, on enregistre un passage du poids de 200 g à 1087 g, un taux de croissance spécifique de 2,20 et une densité finale de 3,74 kg/m². |

| The objective of this work was to identify, by means of different statistical criteria the ideal nonlinear regression model to describe the growth curve of three lineages of caipira broiler for meat production. A total of 90 birds were used, being 30 birds from each of the following lineages: Pescoço Pelado, Carijó and Pesadão Vermelho. The individual body weight of broilers (1, 7, 14, 21,28, 35, 42, 49, 56, 63, 70, 77, 84 and 91 days of age) was collected weekly for determination of growth curves by means of Models von Bertalanffy, Gompertz, Logistic, Richards and Brody. The parameters of Brody model did not converge to the weight of strains. The model that better adjusted to the data was Logistic. |

| Restriction fragment length polymorphism (RFLP) has been detected at the bovine kappa-casein locus. The polymorphism has been analyzed for its effects in cattle production, mostly for milk traits and even for maternal effect on pre-weaning weights. We used polymerase chain reaction - restriction fragment length polymorphism (PCR-RFLP) to genotype 408 Nellore animals for the non-silent mutation (Thr/Ile136 and Asp/Ala148) that characterizes the A and B variants of the polymorphism and compared expected progeny difference (EPD) for a maternal effect on 120 and 210 days weights and direct EPD for 120, 210, 450 and 550 day weight between AA and AB animals. The EPD values were obtained from the University of São Paulo (Brazil) Nellore Cattle Breeding Program,... |

| Morphological characteristics of children commonly imply the processes of growth and development. Information on children's growth in height and their body weight is often used as the indicator of the children's health and nutritional status. As the parameters are changeable both temporally and spatially, it is important to provide their continual assessment. The aim of the study is to investigate the changes in morphological characteristics in a sample of Serbian 7-year-old children in the period 2005 2014. The data was gathered from medical documentation recorded in the period 2005-2014 in the local health-care centre "Dr Dusan Savic Doda" in Beocin, which is situated in the central part of the province Vojvodina, the north-west part of Serbia. Most... |

| Compound indices are often used in the analysis of fish stomach contents to characterize diet. Five of these indices, combining two or three measures of prey importance: weight, abundance and frequency of occurrence, are mathematically compared in this work. Data from a feeding study of sparid fish show that different indices can produce different results. Four classifications of food, in terms of preferences, are applied to Sparidae, compared and discussed. A new method of classifying the prey of fish into groups is proposed. It characterizes the main items in the diet, whatever feeding index is chosen for the analysis. |

| This study was carried out in order to assess commercial front and rear cuts of dairy-origin cattle fed mesquite pod meal. Twenty-five non-castrated male bovines (Holstein-Zebu), distributed according to a completely randomized design, with five animals per treatment, were used. The feed contained about 121.2 and 544.98 g kg-1 of crude protein and total digestible nutrients, respectively, and was composed of tifton grass hay, cornmeal, soybean meal, mesquite pod meal and mineral salt. The right half carcass of each animal was separated between the 5th and 6th ribs, in front and rear quarters, from which commercial cuts were obtained. There was no effect (p > 0.05) as to the replacement of corn for mesquite pod meal on the weights and yields of front... |

| Foram analisados os dados de quatro anos, das fases de cria e recria, de 468 matrizes do sistema de produção da Embrapa Gado de Corte. Esse sistema, com animais da raça Nelore, utilizando pastagens cultivadas e lotação média no período seco de 1,4 unidade animal por hectare, apresentou taxa de prenhez média de 87,5%, sendo 87,3% para as vacas adulttas, 68,8% para as primíparas e 88,5% para as novilhas. Vacas entre o terceiro e sétimo partos foram as mais eficientes, com taxa de prenhez acima de 90%, intervalo de partos de 365 dias e 325 dias para parir após início da estação de acasalamento. O peso médio à desmama foi de 177kg para os machos e 162 kg para as fêmeas, aos 202 dias de idade. As fêmeas de reposição, recríadas somente em pasto, tiveram peso... |

| ABSTRACT: The present study was aimed to evaluate the effect of heavy metals on an important tissue of two fish species Cyprinus carpio and Wallago attu, sampled from the Indus river, Mianwali District, Pakistan. The concentration of selected heavy metals Fe, Cr, Cu, and in gills, muscles, kidney and liver was compared with an International standard of food fish. The overall metal concentrations among different weight categories in C. carpio were in the order of Fe > Cu > Cr >. In W. attu the overall accumulation of these metals were, in order of Fe > Cu > Cr > Pb The order of accumulation of metals in gills and muscle of C. carpio was Fe > Cr > Pb > Cu; kidney and muscles of W. attu was Fe > Cr > Cu > Pb; liver Fe >... |

| Sucralose is a sweetener of general use in over three thousand products (beverages, foods and medical diets), with utilization currently permitted for the general population in more than 80 countries, including for women of reproductive age. There is little information on the safe use of sucralose, and experimental studies have suggested that the administration of some sweeteners, by diverse routes, retards not only fetal and placental development but also umbilical cord size. The present study aimed to estimate the fetal and placental weights and umbilical-cord length in fetuses from rat dams, after ingestion and non-ingestion of sucralose. In the treated group (5 dams), sucralose was administered (via gavage) at the dose of 30 mg/kg/day, from the 10th to... |

| Tobacco is one of the important agricultural and industrial products which plays a crucial role in economics and income of the producing countries and tobacco’s leaves are actually used commercially. In this study, the effects of two tobacco varieties K326 and 347 in three plant spacing of 30, 40, and 50 cm (with density of 33333, 25000 and 20000 plants/ha) on physical properties and weight of tobacco leaves are discussed. The results of variance analysis showed that the ¬¬¬effects of variety and plant spacing on leaf surface in 5% level were significant. Interaction effect of these two factors wasn’t significant. Also results showed that independent and interaction effects of plant spacing and different varieties of tobacco on leaf weight were significant... |
