Silveira,Mauricio Vargas da; Souza,Julio Cesar de; Ferraz Filho,Paulo Bahiense; Silva,Luiz Otavio Campos da; Arruda,Rosana Moreira da Silva; Machado,Carlos Henrique Cavallari; Pereira,Mariana Alencar.
ABSTRACT: The present study aimed to estimate adaptability and stability parameters for Nellore bulls in 3 different regions. The traits analyzed included the weight of the animals raised in pasture at 420 days of age (W420) and at the age at first calving (AFC). The information used in this study was related to the phenotypic mean of the females which were the offspring of the top ten classified bulls based in one region. We used the methods proposed by Finlay & Wilkinson (1963) & Eberhart and Russell (1966) in order to evaluate the parameters of adaptability and stability of these animals. The averages estimated by the method of least squares were 243.91±34.90 kg and 1182.54±57.82 days, respectively, for the traits W420 and AFC. Adaptability and...

Ajustement de certains paramètres de culture par bouturage de Gracilaria verrucosa (algue rouge), Hudson papenfuss, dans le lac de Bizerte (Tunisie) OceanDocs
Ksouri, J.; Mensi, F.; Ben Said, R..
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.

Analysis of growth curves in different lineages of Caipira broiler type Animal Sciences
Araujo, Caroliny Costa; Rodrigues, Kênia Ferreira; Vaz, Roberta Gomes Marçal Vieira; Conti, Ana Carolina Muller; Amorim, Aline Ferreira; Campos, Carla Fonseca Alves.
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.

Analysis of restriction fragment length polymorphism in the kappa-casein gene related to weight expected progeny difference in Nellore cattle Genet. Mol. Biol.
Biase,Fernando H.; Garnero,Analia Del V.; Bezerra,Luiz A.F.; Rosa,Arthur J.M.; Lôbo,Raysildo B.; Martelli,Lúcia.
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,...

Blood parameters and measurements of weight in the rehabilitation of Magellanic penguins (Spheniscus magellanicus, Foster 1781) Arq. Bras. Med. Vet. Zootec.
Martins,A.M.; Silva Filho,R.P.; Xavier,M.O.; Meireles,M.C.A.; Robaldo,R.B..
During the austral winter the appearance of the Magellanic penguin (Spheniscus magellanicus) is common on the southern coast of Brazil. The oil pollution constitutes a major cause of death of these birds. The monitoring of the weight and blood variables is important to make decisions during the rehabilitation and release of these animals. Thus, the aim of this study was to evaluate the relationship between the penguins' survival during rehabilitation and the values of hematocrit (Hct), total plasma protein (TPP) and body weight (BW) of the birds received at Centro de Recuperação de Animais Marinhos (Recovery Centre for Sea Animals) between 2006 and 2009. The analysis took place weekly, and penguins were classified according to the outcome of the...

Changes in Morphological Characteristics During the Period 2005 ­ 2014 in a Sample of Serbian 7 - Year-Old Children International Journal of Morphology
Pavlica,Tatjana; Rakic,Rada; Sironjic,Tijana.
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...

Characteristics of one sea winter Atlantic salmon stock caught on Elorn river from 1974 to 1984 ArchiMer
Prouzet, Patrick; Gaignon, Jean-louis.
From observations gathered on grilse populations sampled during the fishing period (March -mid-June) or after the fishing season, the authors noted: a strong heterogeneity and length, the mean value of which increase from May to December, a sex-ratio not different from 1 male for 1 female, a high relative fecundity superior to those of spring salmon population sampled. The comparison between fish of local and foreign origins did not allow to observe significant differences between the biological characteristics studied (weight, length, sex-ratio and fecundity).

Comparaison de cinq indices alimentaires utilises dans l'analyse des contenus stomacaux ArchiMer
Rosecchi, E; Nouaze, Y.
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.

Almeida, Marina de Paula; Souza, Evaristo Jorge Oliveira de; Véras, Antonia Sherlânea Chaves; Morais, Ítalo Marcos de Vasconcelos; Vítor, Danilo Ribeiro; Silva, José Ricardo Coelho da.
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...

Effect of age of dam on weight of calf in the genetic assessment of Zebu cattle in random regression models Animal Sciences
Ferreira, Jorge Luis; Lopes, Fernando Brito; Bresolin, Tiago; Garcia, José Américo Soares; Minharro, Silvia; Lôbo, Raysildo Barbosa.
Current analysis estimated co-variance components and genetic parameters for growth traits by random regression models taking into consideration the cow’s age on the weight of calves. Genealogical data and records on weights of male and female Zebu cattle, born between 1993 and 2011, were provided by the National Association of Breeders and Researchers (ANCP). Different models were compared by Akaike and Bayesian criteria. Legendre’s orthogonal polynomials were used to model the direct and maternal genetic effects of maternal and animal permanent environmental effects. Joint modeling of cow age at the moment their progenies were weighed resulted in more accurate estimates of co-variance components and genetics parameters. Co-variance functions of the cow...

Effects of Sucralose Ingestion on Fetal and Placental Weights and Umbilical-Cord Length: Experimental Study International Journal of Morphology
Rodero,Ademir B; Batigália,Fernando; Azoubel,Reinaldo; Moura,Arianne Assis; Rodero,Lucas de Souza; Silveira Jr,Landulfo.
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...

Azadbakht, Mohsen; Ghajarjazi, Ehsan; Kiapei, Ali; Jafari, Hassan; Salehi, Ebrahim; Pishgar, Reza.
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...

Equations for calculation of volume and weight of aerial compartiments of eight-year-old Grevillea robusta (Cunn.) trees PFB - Pesquisa Florestal Brasileira
Ferreira, Carlos Alberto; Martins, Emerson Gonçalves; Silva, Helton Damin da.
This paper presents results obtained for fitting equations to estimate volume and weight of aerial compartments of Grevillea robusta trees. Twelve trees representing four provenances were collected from an eight-year-old provenance trial located in the municipality of Anhembi, State of São Paulo. The trunks of the trees were segmented until the minimum diameter of 5 cm. The heartwood was measured till the height it was possible to be distinguished in the tree. Allometric models were the most suitable for this paper proposes. The inclusion of the combined variable (total height multiplied by the diameter at breast height) contributed to a better adjustment of most equations. The standard errors of the estimates were relatively high for heartwood and bark...

Estimación del crecimiento y mortalidad del chivo cabezón Ariopsis bonillai (Miles, 1945) (Pisces: Siluriformes: Ariidae), en la Ciénaga Grande de Santa Marta, Colombia OceanDocs
Galvis-Cortés, O.D..
A partir de septiembre de 1981 y durante 14 meses consecutivos de muestreo en la Ciénaga Grande de Santa Marta, se capturaron 3477 ejemplares de chivo cabezón Ariopsis bonillai (Miles, 1945). Con base en estas capturas, se estimó la relación tallapeso para hembras y machos en forma separada y en conjunto. Se obtuvieron las curvas de crecimiento según von Bertalanffy en talla y peso para ambos sexos y también los valores preliminares de las tasas de mortalidad natural (M), total (Z) y por pesca (F) Se analiza la variación de estos resultados entre sexos como una función causaefecto, originada por el fenómeno de la incubación oral característico en la especie.
