Mitochondrial DNA single nucleotide polymorphism associated with weight estimated breeding values in Nelore cattle (Bos indicus)
Provedor de dados: 74
Autores: Biase,Fernando Henrique; Meirelles,Flávio Vieira; Gunski,Ricardo; Vozzi,Pedro Alejandro; Bezerra,Luiz A.F.; Vila,Reginaldo A.; Rosa,Artur J.M.; Lôbo,Raysildo B.; Martelli,Lúcia.
We sampled 119 Nelore cattle (Bos indicus), 69 harboring B. indicus mtDNA plus 50 carrying Bos taurus mtDNA, to estimate the frequencies of putative mtDNA single nucleotide polymorphisms (SNPs) and investigate their association with Nelore weight and scrotal circumference estimated breeding values (EBVs). The PCR restriction fragment length polymorphism (PCR-RFLP) method was used to detect polymorphisms in the mitochondrial asparagine, cysteine, glycine, leucine and proline transporter RNA (tRNA) genes (tRNAasn, tRNAcys, tRNAgly, tRNAleu and tRNApro). The 50 cattle carrying B. taurus mtDNA were monomorphic for all the tRNA gene SNPs analyzed, suggesting that they are specific to mtDNA from B. indicus cattle. No tRNAcys or tRNAgly polymorphisms were...

Analysis of restriction fragment length polymorphism in the kappa-casein gene related to weight expected progeny difference in Nellore cattle
Provedor de dados: 74
Autores: 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,...

La production chez les crustacés. Rôle dans les écosystèmes et utilisations
Provedor de dados: 5
Autores: Khmeleva, N; Goloubev, A.
This monograph is the first to state by a systematic research the rules which control the production of the organic losses in shape of eggs and exoskeletons during the life of Crustacea. The weight and the energy content of the material thrown out are the chief criteria selected to characterize the germinal production, relative to the egg-mass, and the exuvial production, relative to the organic fraction of the exoskeleton. The determination of these parameters, at the level of the organism or of the population, takes into account the systematic position of the animals, the duration of their intermolt periods, fecundity and other indices in relation to environmental factors. The loss of matter and energy with reproduction and molting(studied for different...

Characteristics of one sea winter Atlantic salmon stock caught on Elorn river from 1974 to 1984
Provedor de dados: 5
Autores: 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
Provedor de dados: 5
Autores: 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.

Head Circumference in Canadian Male Adults: Development of a Normalized Chart
Provedor de dados: 77
Autores: Nguyen,A.K.D; Simard-Meilleur,A. A; Berthiaume,C; Godbout,R; Mottron,L.
Macrocephaly has been reported as one of the few physiological markers of several syndromes which are identified during childhood. However, only a limited number of studies have investigated whether macrocephaly persists in adults in these conditions, due to an absence of up-to-date reference charts constructed for typically developing adults. Available adult head circumference reference charts either don't measure individuals beyond 21 years of age, are outdated, mostly use homogeneous samples and most importantly do not account for the individual's height and weight at the same time. Two hundred twenty-one male adults were recruited in a large urban community. For each participant, height, weight and head circumference were measured. A significant...

The Effect of Walnut on the Weight, Blood Glucose and Sex Hormones of Diabetic Male Rats
Provedor de dados: 77
Autores: Ghorbani,R; Mokhtari,T; Khazaei,M; Salahshoor,M. R; Jalili,C; Bakhtiari,M.
Diabetes leads to reproductive dysfunctions by producing free radicals. It seems that using walnut can be effective in the damage induced by diabetes. The aim of the present study was to evaluate the effects of walnut consumption on sex hormones in diabetic Wistar male rats induced by STZ (streptozotocin). Diabetes animals were induced by STZ (60 mg/kg). Rats were randomly divided into 5 groups (n=6), including normal diet and healthy (Sham), Diabetic by normal diet (control) and diabetic by 6, 9 and 12% walnut in their diet (experimental groups), and were examined for 6 weeks. Body weight, blood glucose (3 times), and sex hormones (testosterone, FSH and LH) were measured. Overall, in terms of the mean index, there was a significant difference in the...

Study of Wistar Rats Heart at Different Stages in the Evolutionary Cycle
Provedor de dados: 77
Autores: De Carvalho,C. A. M; Thomazini,J. A.
The rat is probably the most commonly used animal in scientific research. There are many benefits to its use such as: ability to work a large number of animals allowing greater statistical validity, the relatively short life cycles. However, the scant literature regarding the anatomy and morphology of these animals is also old and not very descriptive. The objective of this research is to study the macroscopic morphometric aspects of several parameters that have not been described yet regarding the heart of Wistar rats in different phases of their lives. Thirty-six adult male and female rats (Rattus norvegicus) weighting 150-770 g were randomly divided into 6 experimental groups. The heart was then carefully dissected and removed from the chest. After this...

Effects of Sucralose Ingestion on Fetal and Placental Weights and Umbilical-Cord Length: Experimental Study
Provedor de dados: 77
Autores: 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...

Liveweight and Chest Girth Correlation in Commercial Sheep and Goat Herds in Southwestern Nigeria
Provedor de dados: 77
Autores: Olatunji-Akioye,A. O; Adeyemo,O. K.
The correlation between chest girth and weight of sheep and goats have been studied as a predictive guide in homestead farms where equipment to definitively quantify the weight of animals are unavailable and inaccessible. The livestock markets in the South Western part of Nigeria are still very underdeveloped and consist of peasant farmers taking their few animals to more developed areas to offer them for better prices to the consumer or middle men who are in the trade to attain the best profit. Twenty each of sheep and goats were randomly selected in herds from three different commercial locations and evaluated using weight and chest girth measurements as indices. Mean weight for the 3 groups of sheep was between 19.8 and 31.15kg, while for the 3 groups...

Changes in Morphological Characteristics During the Period 2005 ­ 2014 in a Sample of Serbian 7 - Year-Old Children
Provedor de dados: 77
Autores: 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.

Provedor de dados: 77
Autores: Mejía Huerta,Nancy Guadalupe; Córdova Izquierdo,Alejandro; Aragón Hernández,Jesús; Flores Pérez,Fernando Iván; Pérez-Martínez,Mario.
Two groups were formed in order to evaluate the effect of an obesogenic diet on body and liver weight, body fat accumulation and the histometric characteristics of liver and testicles of New Zealand rabbits during the peripuberal period. One group received a standard farm diet and the other received a standard farm diet with canola oil added. During the study, weight of both groups was recorded. At the end of the study, the rabbits were euthanized and liver, testicles, and visceral, scapular and scrotal fat were weighed. Tissue samples were obtained from liver and testicles to carry out histometric analysis. Body weight, body mass index, liver and visceral fat weight were significantly different (P&lt;0.01) in the obesogenic diet when compared to the...

Provedor de dados: 83
Autores: Fonseca,Alinca Peres da; Volcan,Matheus Vieira; Sampaio,Luís André; Romano,Luís Alberto; Robaldo,Ricardo Berteaux.
Given the importance of knowledge of the biology of endangered species for the planning of conservation and management efforts, the aim of this study was to investigate the influence of temperature on the growth of Austrolebias wolterstorffi (Ahl, 1924). To clarify the thermal influence on the growth of the species, temperatures of 16, 20, 24 , and 28°C were tested in triplicate. The present study showed that a water temperature of 28°C is detrimental to the growth of the species. Among the other tested temperatures, it was found that the optimum temperature for growth decreases as an individual ages and is slightly lower for females. It was demonstrated here that males reach a higher weight and length, and grow faster than females, reaching sexual...

Two experiments were performed in order to determine the effect of supplementation of dry foods with live &lt;i&gt;Artemia&lt;/i&gt; nauplii on the growth, survival, rate of cannibalism, and length-weight relationships of &lt;i&gt;Clarias gariepinus&lt;/i&gt; larvae. It was found that &lt;i&gt;Artemia&lt;/i&gt; -supplementation resulted in a significantly higher growth rate. The "condition", expressed as a length-weight relationship, was likewise altered after supplementation. The survival and rate of cannibalism were not influenced by supplementation. &lt;i&gt;Artemia&lt;/i&gt; -supplementation of dry foods was compared with other approaches which are based on the concept of the 'adaptation weight'.

Autores: Cubas, Rafael; Costa, Emanuel Arnoni; Guimarães Finger, César Augusto; Maydanchen, Viviane Zaniz.
Reliable biomass data are very important in the evaluation of ecosystems, and help in understanding the contribution of forests in climate change. Variables that describe the size of the tree, like diameter and height are directly associated with biomass, which allows the use of regression models to estimate this element. Therefore, this study aimed to estimate by regression models, the biomass of different compartments of natural regeneration of trees of a Pinus taeda L. stand. The data were obtained through direct destructive method, using 100 randomly selected trees in the understory of a stand of Pinus taeda. We analyzed three arithmetical models, three logarithmic and two models developed by Stepwise process. Logarithmic equations developed by...

Equations for calculation of volume and weight of aerial compartiments of eight-year-old Grevillea robusta (Cunn.) trees
Provedor de dados: 190
Autores: 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...

THE ROLE OF ECONOMICS IN EATING CHOICES AND WEIGHT OUTCOMES
Provedor de dados: 31
Autores: Mancino,   Lisa; Lin,   Biing-Hwan; Ballenger,   Nicole.
We use data from the USDA's 1994-96 Continuing Survey of Food Intakes by Individuals and the 1994-96 Diet and Health Knowledge Survey to ascertain whether economic factors help explain weight differences among adults. Weight differs among demographic subgroups, and differences in specific behaviors, health awareness, and eating patterns can be linked to weight outcomes. An economic framework helps explain how socioeconomic factors affect an individual's ability to achieve good health. Our results suggest that income, household composition, and formal education help explain variation in behaviors and attitudes that are significantly associated with weight outcomes.

Autores: 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...

Retrospective study of allometric relationship between heart rate, electrocardiographic parameters and bodyweight in dogs
Provedor de dados: 45
Autores: Aleixo,A.S.C.; Alfonso,A.; Fillippi,M.G.; Chiacchio,S.B.; Lourenço,M.L.G.
ABSTRACT The allometric relationship between bodyweight (BW) and heart rate (HR) has been described as inversely proportional in domestic species, but that has been refuted. The relationship between HR and electrocardiographic variables is described in literature. However, studies about the variation and influence of factors on the hemodynamic and electrocardiographic parameters in dogs are not abundant. As the metabolic rate is defined as the production and dissipation of heat by the body surface area (BSA) in m², it is essential to define that relationship. A retrospective study was conducted to analyze the correlation between HR, ECG parameters and BW in dogs. One thousand electrocardiographic tracings were analyzed in addition to the ECG parameters and...

Autores: 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...

Use of nucleotides in weanling rats with diarrhea induced by a lactose overload: effect on the evolution of diarrhea and weight and on the histopathology of intestine, liver and spleen
Provedor de dados: 56
Autores: Norton,R.; Leite,J.; Vieira,E.; Bambirra,E.; Moura,C.; Penna,G.; Penna,F.
Until recently, dietary sources of nucleotides were thought not to be essential for good nutrition. Certain states with higher metabolic demands may require larger amounts that cannot be provided by endogenous production. The objective of the present study was to determine the action of nucleotides on the recovery from lactose-induced diarrhea in weaned rats. Thirty-six weanling Fisher rats were divided into two groups. Group 1 received a standard diet and group 2 received a diet containing lactose in place of starch. On the 10th day, six animals per group were sacrificed for histopathological evaluation. The remaining animals were divided into two other subgroups, each with 6 animals, receiving a control diet, a control diet with nucleotides (0.05%...

The aim of the study was to evaluate the influence of different temperature control systems on the voluntary feed intake (VFI), percentage of weight loss (PWL) and performance of lactating sows as well as on the weight of their piglets. Two systems were used: traditional temperature control system (TTCS) with curtain management and an evaporative snout cooling system (ESCS). The study was performed during the summer of 2011. After farrowing and at the weaning, 241 sows were weighed to evaluate the PWL during lactation. TTCS sows lost more weight (5.3±0.9%; P&lt;0.05) than ESCS sows (2.2±0.9%). VFI was measured at intervals of four days in 32 primiparous and 39 multiparous sows. ESCS sows had higher VFI (5.8±0.2kg day-1; P&lt;0.05) than TTCS sows (4.8±0.2kg...

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 &amp; Wilkinson (1963) &amp; 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...
