IGF-1 y actividad ovárica en la fase folicular tardía de cabras suplementadas con proteina no degradable en rumen en diferente condición corporal
Provedor de dados: 32
Autores: Guerra García, Minerva.
La influencia de la nutrición en la función ovárica se clasifica como “efecto estático”,  “efecto dinámico” (Meza-Herrera et al., 2004) y “efecto agudo” (Scaramuzzi et al.,  2006).  Dichos efectos son mediados por cambios en los niveles de hormonas  metabólicas y de la superfamilia de factores de crecimiento (Meza-Herrera et al.,  2006), pero su importancia relativa y rutas de acción necesitan ser dilucidados   (Martin et al., 2004).  Se utilizaron 32 cabras de 19 meses de edad, F1  (AlpinoxNubia), sometidas a un periodo de adaptación de 40 días, registrando los  pesos corporales y la condición corporal (Russel et al., 1969), al inicio y cada quince  días en ayunas.  A partir del día 40, la dieta consistió de heno de alfalfa molido y dos  niveles de...

Condition corporelle et conséquences sur la plasticité des traits d’histoire de vie chez les petits pélagiques de Méditerranée
Provedor de dados: 5
Autores: Brosset, Pablo.
Multiple changes have been described since 2008 in the Gulf of Lions ecosystem and particularly in small pelagic fish dynamic. In particular, the two main exploited species, i.e. anchovy (Engraulis encrasicolus) and sardine (Sardina pilchardus) are now smaller and in poor condition while a third species, the sprat (Sprattus sprattus) strongly increased in terms of biomass and abundance. This PhD thesis investigated these changes through the analysis of small pelagic fish body condition (i.e individual energy stores) variations, its causes and consequences. Anchovy and sardine body condition was optimal in 2005 and 2006 and decreased after 2008 to remain steady at low level since 2010. Moreover, older sardine have particularly displayed poor body condition...

Determinism of Temporal Variability in Size at Maturation of Sardine Sardina pilchardus in the Bay of Biscay
Provedor de dados: 5
Autores: Véron, Matthieu; Duhamel, Erwan; Bertignac, Michel; Pawlowski, Lionel; Huret, Martin; Baulier, Loic.
Age and size at maturation appear as key parameters governing the dynamics of a population as they affect growth rate, fecundity, and survival. The expression of such life history traits is determined by genetic make-up and modulated by environmental factors mainly through phenotypic plasticity. Moreover, fishing, besides decreasing population size and changing demographic composition can alter allelic frequencies through fisheries-induced evolution by selecting for some particular traits. In the Bay of Biscay, a decreasing trend in both sardine body condition and size-at-age has recently been pointed out at the population level. The Probabilistic Maturation Reaction Norm (PMRN) approach was applied to help disentangle phenotypic plasticity and genetic...

Maternal oxidative stress and reproduction: testing the constraint, cost and shielding hypotheses in a wild mammal
Provedor de dados: 5
Autores: Viblanc, Vincent A.; Schull, Quentin; Roth, Jeffrey D.; Rabdeau, Juliette; Saraux, Claire; Uhlrich, Pierre; Criscuolo, François; Dobson, F. Stephen.
1.Oxidative stress has been proposed as a central causal mechanism underlying the life history trade-off between current and future reproduction and survival in wild animals. 2.Whereas mixed evidence suggests that maternal oxidative stress may act both as a constraint and a cost to reproduction, some studies have reported a lack of association between reproduction and maternal oxidative stress. 3.The oxidative shielding hypothesis offers an alternative explanation, suggesting that mothers may pre-emptively mitigate the oxidative costs of reproduction by increasing antioxidant defences prior to reproduction. 4.We tested the oxidative constraint, cost, and shielding hypotheses using a longitudinal field study of oxidative stress levels in a species that...

Densité d'élevage chez la truite arc-en-ciel (Onchorynchus mykiss W.). Conséquences sur la qualité de la chair et l'état apparent
Provedor de dados: 5
Autores: Sampietro Coloh, Sonia.
A triploid strain of rainbow trout (Onchorynchus mykiss) was reared in two experiments testing density effect on growth and flesh quality. Physiological index and corporal condition were also considered. Environmental  parameters were maintained identical between densities. Two fold 20, 50 and 80 Kg m·3 stocking densities were reared at 1.3% daily ration. No differences were found in fish growth neither in fish quality. A second experience compared two densities (50 and 110 kg m-3 ) and oxygen supplementation. Fish were fed ad libitum. Weight gain diminished at higher densities and oxygen supplementation had a favourable effect on fish growth. No differences were found in flesh quality parameters tested.

Negative effects of wind speed on individual foraging performance and breeding success in little penguins
Provedor de dados: 5
Autores: Saraux, Claire; Chiaradia, Andre; Salton, Marcus; Dann, Peter; Viblanc, Vincent A.
Most effects of environmental and climate variability on predator life history traits and population dynamics result from indirect effects mediated through the food chain. There is growing evidence that wind strength might affect seabirds while foraging at sea. Here, we investigated the effect of wind speed on the foraging performance of a flightless marine predator, the little penguin (Eudyptula minor). To this end, we used satellite-derived wind data collected over 11 breeding seasons during which the daily attendance and body mass changes of more than 200 penguins breeding at Phillip Island (Victoria, Australia) were recorded by an automated penguin monitoring system. Over 17 363 foraging trips, we found that wind speed had important effects on foraging...

Telomere length reflects individual quality in free-living adult king penguins

Autores: Le Vaillant, Maryline; Viblanc, Vincent A.; Saraux, Claire; Le Bohec, Celine; Le Maho, Yvon; Kato, Akiko; Criscuolo, Francois; Ropert-coudert, Yan.
Growing evidence suggests that telomeres, non-coding DNA sequences that shorten with age and stress, are related in an undefined way to individual breeding performances and survival rates in several species. Short telomeres and elevated shortening rates are typically associated with life stress and low health. As such, telomeres could serve as an integrative proxy of individual quality, describing the overall biological state of an individual at a given age. Telomere length could be associated with the decline of an array of physiological traits in age-controlled individuals. Here, we investigated the links between individuals' relative telomere length, breeding performance and various physiological (body condition, natural antibody levels) and life...

Major changes in sardine growth and body condition in the Bay of Biscay between 2003 and 2016: Temporal trends and drivers
Provedor de dados: 5
Autores: Veron, Matthieu; Duhamel, Erwan; Bertignac, Michel; Pawlowski, Lionel; Huret, Martin.
In the Bay of Biscay, mean body length and weight of sardines (Sardina pilchardus) have been decreasing since the early 2000s and could severely impact the fishing and seafood industry sector. These trends have no apparent link with fishing pressure, although the latter has been increasing since the late 2000s. As part of an effort to develop suitable assessment and management tools for this stock, we investigated the life-history traits of sardine and analyze its seasonal and inter-annual variations. Based on 14 years of morphometric data from both scientific surveys and professional samples, we analyzed the variability in sardine body condition and its responses to environmental changes. Generalized Additive Models revealed an age-sex specific decreasing...

Autores: Queiros, Quentin; Fromentin, Jean-marc; Gasset, Eric; Dutto, Gilbert; Huiban, Camille; Metral, Luisa; Leclerc, Lina; Schull, Quentin; Mckenzie, David; Saraux, Claire.
Small pelagic fish are key components of marine ecosystems and fisheries worldwide. Despite the absence of recruitment failure and overfishing, pelagic fisheries have been in crisis for a decade in the Western Mediterranean Sea because of a marked decline in sardine size and condition. This situation most probably results from bottom-up control and changes in the plankton community toward smaller plankton. To understand such an unusual phenomenon, we developed an original and innovative experimental approach investigating the mechanisms induced by a reduction in the quantity and size of sardine prey. While experimentations offer the unique opportunity to integrate behavior and ecophysiology in understanding key demographic processes, they remain rarely...

The change of animal biometrics (body mass and body size) can reveal important information about their living environment as well as determine the survival potential and reproductive success of individuals and thus the persistence of populations. However, weighing individuals like marine turtles in the field presents important logistical difficulties. In this context, estimating body mass based on body size is a crucial issue. Furthermore, the determinants of the variability of the parameters for this relationship can provide information about the quality of the environment and the manner in which individuals exploit the available resources. This is of particular importance in young individuals which growth quality might be a determinant of adult fitness....

Evaluation of Three Mathematical Functions to Describe the Relationship Between Body Weight, Body Condition and Testicular Dimensions in Yankasa Sheep
Provedor de dados: 77
Autores: Yakubu,A; Musa-Azara,I. S.
Body size and testicular measurements have been found to be important parameters utilized in breeding soundness evaluation. The present study therefore, aimed at determining the relationship between body weight (BW), body condition score (BCS), testicular length (TL), testicular diameter (TD) and scrotal circumference (SC) in 120 extensively reared Yankasa rams (approximately 30 months old) using linear, quadratic and cubic predictive models. Coefficient of determination (R2), Adjusted R2, the estimate of Mallows' Cp, RMSE (Root mean squares error) and the parsimony principle (p=number of parameters) were used to compare the efficiency of the different models. Strong Pearson's correlation coefficients (r = 0.83-0.94; P&lt;0.01) were found between BW, TL,...

Food limitation and low-density populations of sympatric hamster species in North China
Provedor de dados: 16
Autores: Xiong, W.; Liang, H.; Yu, X.; Cong, L.; Zhang, Z.
Although food has been proposed as a possible factor on population regulation of small mammals, evidence of food restriction in field conditions is still lacking. Food restriction is generally thought to occur in high-density years of oscillating populations of small mammals. By using two body condition indices (muscle protein concentration and cleaned carcass index), we investigated variations of body condition of the greater long-tailed hamster (Tscherskia triton) and the striped hamster (Cricetulus barabensis) in the Raoyang County of the North China Plain during a population decline- and low-phase from 1998 to 2003. Our laboratory experiments showed that food restriction reduced muscle protein concentration and cleaned carcass index of greater...

Reproductive biology of the peacock bass Cichla piquiti (Perciformes: Cichlidae), an exotic species in a Neotropical reservoir
Provedor de dados: 83
Autores: Vieira,Augusto B. C.; Salvador-Jr.,Luiz F.; Melo,Rafael M. C.; Santos,Gilmar B.; Bazzoli,Nilo.
To analyze the reproductive biology of the peacock bass Cichla piquiti, 361 specimens were collected bimonthly in the Itumbiara Reservoir, southeast Brazil, from December 2004 to November 2005. Males and females in reproductive activity occurred during almost the entire year, with reproductive peak occurring before the beginning of the rains when the water temperature remained low, indicating that these environmental variables do not directly influence in the reproduction of C. piquiti. The long reproductive period, partially spent ovaries contained postovulatory follicles and oocytes in all developmental stages, indicate asynchronous development of oocytes and multiple spawning. The mean total lengthand body weigth were, respectively, 38.2 ± 7 cm and...

Body mass index and glucose variations during the night in free-ranging Artibeus planirostris (Chiroptera: Phyllostomidae)
Provedor de dados: 103
Autores: Azeredo,Luane Maria Melo; Ximenes,Monique Silva; Pereira,Kleytone Alves; Fracasso,Maria Paula Aguiar; Lopez,Luiz Carlos Serramo.
ABSTRACT Body condition is an important measure to estimate the energy reserve of an organism. Scientists frequently use body condition indices (BCIs) with morphometric measures but direct measurements, such as blood glucose, seem to be more reliable. We observed oscillations in the body condition and glucose indexes of individuals of Artibeus planirostris (Spix, 1823) during 13 nights in the field. We assume that if glucose levels are proportional to feeding state and body condition is a measure of energy reserve, blood glucose and BCI should be positively correlated and both are expected to increase during the night as the bats leave their diurnal roost to feed. To test this, we examined the relationship between blood glucose levels, BCI and reproductive...

Thirty-two adult lambs with 105 days of gestation, average live weight of 57.55 kg and average body condition scores of 3.42 were used in the beginning of the experiment. The animals were confined in collective pens, distributed randomly in three treatments: 2.4; 2.2 and 2.0 Mcal of metabolizable energy (ME)/kg of dry matter (DM). Feed supply was ad libitum during the last third of gestation and lactation. Weaning occurred at 70 days. Body...

Autores: Vaz,Ricardo Zambarda; Lobato,José Fernando Piva; Pacheco,Paulo Santana.
This experiment evaluated the performance of 84 Braford steers grazing on summer and winter cultivated pastures fed or not fed an energy-protein supplement. Steers were 10 months old and weighed, on average, 165 kg at the beginning of the trial. Steers grazed on cultivated winter pasture, consisting of black oats (Avena strigosa) and ryegrass (Lolium multiflorum Lam.), and then on cultivated summer pasture, consisting of Napier grass (Pennisetum purpureum). The following treatments were applied: SS - supplement was fed during both seasons; SN - supplement was fed only during the winter; NS - supplement was fed only during the summer; and NN - steers were not fed any supplement. Supplementation resulted in higher body weight and better body condition score...

Autores: Arraes,Débora Regina dos Santos; Tavares-Dias,Marcos.
Predation and alteration of microhabitats may represent high risk for nesting of Amazonian turtles. This study aimed at investigating the nesting and body parameters of neonates of Podocnemis unifilis in the Araguari River basin, State of Amapá, Brazil. The spawning sites of this turtle were monitored along the Falsino River (a region with two reserves) and in the urban area of the Porto Grande city along the Araguari River, from August to December 2011. A total of 180 nests were found and the nesting occurred from September to November, with prevalence in October. Eggs hatching occurred in December. The mean incubation period was 63.5 ± 5.2 days and the eggs hatching success was 25%. However, approximately 80% of the nests had suffered predation mainly by...

Host-parasite interaction between crustaceans of six fish species from the Brazilian Amazon
Provedor de dados: 3
Autores: Vasconcelos, Huann Carllo Gentil; Tavares-Dias, Marcos.
Host-parasite interactions between crustaceans and six fish species (Psectrogaster falcata, Ageneiosus ucayalensis, Acestrorhynchus falcirostris, Hemiodus unimaculatus, Serrasalmus gibbus and Geophagus proximus) from a reservoir in eastern Amazon, northern Brazil, were investigated. Eight hundred and seventy-eight parasites belonging to three crustacean species, Excorallana berbicensis, Argulus chicomendesi and Ergasilus turucuyus, which parasitized the hosts’ mouth, gills and tegument, were collected from 295 fish and examined. High infestation levels were caused by E. berbicensis on the body surface of the hosts. Excorallana berbicensis showed aggregate dispersion, except in S. gibbus, while E. turucuyus showed random dispersion in A. falcirostris. The...

Abstract:  The immune state is an essential component of survival as it directly influences physiological performance and health status. Variation in the leukocyte profile, a significantly increase in body temperature, and a detriment of the eco-physiological performance are among the possible consequences of an unhealthy state. In this study we analyse and discuss how field body temperature, preferred body temperature, the speed for sprint and long runs, locomotor stamina, and body condition can be affected by the immunological state (i.e. leukocyte profile) in a wild population of Liolaemus sarmentoi. Juveniles and adult males with a high percentage of eosinophils, basophils, and a low percentage of monocytes preferred higher body temperatures in a...

Relationship among body condition at parturition, decrease of backfat thickness and weight during the lactation and the interval from weaning to oestrus of sows
Provedor de dados: 62
Autores: GUEDES,Roberto Maurício Carvalho; NOGUEIRA,Raimundo Hilton Girão.
The main objectives of this study were to verify the relationship among body condition at parturition, decrease of backfat thickness and weight during the lactation and the interval from weaning to oestrus of sows. It was performed with 10 gilts and 10 fifth, sixth and seventh parity Camborough sows. The average breeding age and weight of the gilts were respectively 231 days and 149.5 kg. During lactation all females were fed a wet diet (3.34 Mcal/kg, 17% CP), ad libitum. The average daily food consumption was 5.233 for gilts and 5.721 kg for multiparous sows. Ultrasonic measurements of backfat at the P2 site were recorded on day 6 before and days 2, 7, 14, 21 and 25 after parturition. Body weight was recorded on the same dates, except the day before...

Provedor de dados: 65
Autores: Rivera,Nancy Lorena Montaño; Félix,Ananda Portela; Ferreira,Fabiano Montiani; Silva,Ana Vitória Fisher da; Maiorka,Alex.
Studies with human beings and animals have shown that dietary conjugated linoleic acid (CLA) promotes changes in body structure, markedly, body fat reduction. This research aimed to assess the effect of CLA (60% of conjugated linoleic acid methyl ester, at the proportion of 1:1 of the 9, 11: 10, 12 isomers) on changes in body weight, subcutaneous tissue thickness, body fat mass and concentration of serum lipids (triacylglycerols, total cholesterol, LDL and HDL) in overweight dogs. Dogs of different breeds weighting 16.85±7.13 assigned in a randomized assay. Two types of diets were offered for 120 days: control (-CLA) and test (+CLA, 0.3%). There was no difference between control and test groups considering body weight and serum levels of triacylglycerols,...
