The hepatic expression and plasma concentrations of IGF-I were investigated in three broiler chicken strains selected for different growth rates (HP-Hubbard-Pettersen, a fast growing strain; NN-Naked-neck, a strain with an intermediate growth rate and a heterozygous genotype, and C-Caipira, a slow growing crossbred strain). The chickens were studied at 1, 21 and 42 days of age and had free access to food throughout the study. Hepatic IGF-I mRNA expression was assessed by dot blot analysis using a randomly labeled chicken IGF-I cDNA as the probe and plasma IGF-I concentrations were assayed by radioimmunoassay. The hepatic levels of IGF-I mRNA increased from 1 to 21 days of age in all strains, with NN chickens showing a higher (p &lt; 0.05) IGF-I expression...

Provedor de dados: 5
Autores: Hulot, V.; Saulnier, Denis; Latchere, O.; Maihota, N.; Gaertner-mazouni, N.
The purpose of our study is to investigate (1) the influence of phenotype plasticity and local adaptation on pearl-oyster physiology by testing the persistence of growth differentiation of two pearl oyster populations (Arutua and Mangareva) in common garden experiment; (2) to quantify the influence of biofouling development on the growth of each pearl oyster population. According to our observations, the growth rate in terms of total oyster weight suggested better growth performance of the pearl oyster Pinctada margaritifera in Mangareva (0.21–0.24 ± 0.01 g.day−1) than Arutua (0.14–0.15 ± 0.01 g.day−1). However, similar growth performances are observed at the Vairao common garden site for oyster stocks from Mangareva (0.07 ± 0.01 mm.day−1 or...

Growth Performance Comparison of Pinctada margaritifera Juveniles Produced by Thermal Shock or Gonad Scarification Spawning Procedures
Provedor de dados: 5
Autores: Ky, Chin-long; Lau, Christophe; Sham Koua, Manaarii; Lo, Cedrik.
The black-lipped pearl oyster Pinctada margaritifera is of high economic importance in French Polynesia. Arecent decline in pearl value led to the initiation of several genetic breeding programs aiming to improve production traits, including oyster shell growth, which dictates the time of grafting, size of the implanted nuclei, and biomineralization capacities. We assessed shell diameters on hatchery-produced spat to analyze juvenile growth performance of four half-sib families derived from polyandry (one dam crossed with two sires) and polygyny (two dams crossed with one sire) using gametes obtained by thermal shock or gonad scarification. Spat growth was monitored over 3 mo, with shell diameter measured weekly. Results revealed that the spawning method...

Shell Growth Performance of Hatchery Produced Pinctada margaritifera: Family Effect and Relation with Cultured Pearl Weight
Provedor de dados: 5
Autores: Ky, Chin-long; Le Moullac, Gilles.
Size is the most important and valuable quality trait of cultured pearls produced by the black-lipped pearl oyster, Pinctada margaritifera. In French Polynesia, several breeding programmes have been started that aim to improve this size trait, which is highly related to shell growth rate in both recipient and donor oysters. Shell growth rate dictates the time of grafting, size of implanted nuclei and bio-mineralisation potential of the mantle and pearl sac. We assessed shell growth rate through routine digital shell biometric analysis on 22 hatchery families produced between 2005 and 2008. These included full-sib families and half-sib families derived from polyandry (one dam crossed with two or more sires). Results showed that: 1) a significant family...

Autores: Company, Rubén; Calduch Giner, Josep; Perez Sanchez, Jaume; Kaushik, Sadasivam.
The common dentex (Dentex dentex) is a sparid fish which is considered a suitable candidate for Mediterranean aquaculture. A seven-weeks feeding trial was conducted over the summer period with common dentex, sea bream (Sparus aurata) and sea bass (Dicentrarchus labrax). All three species were fed to visual satiety with two practical diets with varying crude protein and crude fat levels (55 % protein, 9 % lipids; 46 % protein, 17 % lipids). The initial body weights were 8.2, 11.6 and 17.3 g for common dentex, sea bass and sea bream, respectively. In all cases, specific growth rates were not significantly affected by dietary treatment, but they varied among species (sea bass 1.7-1.8 %; sea bream 2.1-2.3 %; common dentex 3.1-3.2 %). When comparisons between...

Provedor de dados: 89
Autores: Mushtaq,MMH; Ahmad,G; Parvin,R.
ABSTRACTThe digestible lysine requirement for the growth performance of broilers fed diets with decreasing energy to protein ratio and reared under subtropical summer conditions were determined. Treatments consisted of five wheat-based diets with five levels (0.90, 0.95, 1.00, 1.05 and 1.10%) of digestible lysine (DL) and lowering energy to protein ratio (EPR; 13.6, 12.8, 12.0, 11.4 and 11.0), with five replicates of 80 birds each (n = 2000). Body weight gain (BWG) significantly increased by increasing DL levels during wk 1 (p&lt;0.001), while 1.05% DL promoted the highest BWG during the whole experimental period (p&lt;0.01). Increasing DL level resulted in significant reduction in feed intake (FI) and BWG to DL intake ratio (BWG:DLI) during wk 1-3...

Manipulation of growth of the Amazonian fish tambaqui, Colossoma macropomum (Characiformes: Serrasalmidae): analysis of physiological and zootechnical aspects
Provedor de dados: 36
Autores: PAZ,Arlan de Lima; VAL,Adalberto Luis.
ABSTRACT Colossoma macropomum, known locally as tambaqui, is the native fish most farmed in Brazil, however, technological advances are needed to reach efficient production rates. Modulating growth factors, such as growth hormone, may be associated with improved growth rate and feed efficiency. The use of exogenous hormone for fish rearing is prohibited in Brazil, yet the experimental use of bovine hormone can be useful in research aimed at understanding how to stimulate endogenous growth hormones in fish. Therefore, the present study had the strict objective of understanding the effects of growth hormone on the physiology and zootechnical parameters of C. macropomum under experimental conditions. The animals were intraperitoneally injected every fifteen...

Abstract Growth and immune response of Pangasius hypophthalmus were evaluated after feeding the fish with diets containing hot-water extracts (HWE) of Sargassum oligocystum as immunostimulant at 100, 300, and 500 mg kg-1 diet. Basal diet for P. hypophthalmus served as the control. The experimental diets were administered for 12 weeks. At the end of the feeding experiment, growth and haematological profile of fish were evaluated. Result showed that final weight, weight gain, daily growth rate and feed conversion ratio were significantly increased in the fish that received 300 and 500 mg kg-1 HWE of S. oligocystum. Evaluation of the haematological profile showed that white blood cells red blood cells, hemoglobin, hematocrit and platelet of P. hypophthalmus...

A.J. Hernández, S. Satoh, and V. Kiron. 2013. The effect of citric acid supplementation on growth performance, phosphorus absorption and retention in rainbow trout (Oncorhynchus mykiss) fed a low-fishmeal diet. Cien. Inv. Agr. 40(2): 397-406. Two feeding experiments were conducted to investigate the effect of a low-phosphorus (P) diet in combination with citric acid (CA) on rainbow trout growth performance and P utilization. In the first 12-week trial, duplicate groups of 30 fish (12.0±1.7 g) were fed one of five diets. The basal diet was formulated with low-P protein sources and 15% fishmeal (FM) without inorganic P supplementation. The test diets contained 0.5% monocalcium phosphate (MCP), 3% CA or both. A FM-based diet served as the positive control....

Autores: Vásquez-Torres,Wálter; Pereira-Filho,Manoel; Arias-Castellanos,Jose Alfredo.
A growth experiment was conducted to determine the optimal dietary protein requirement for juvenile cachama, Piaractus brachypomus. Six semi-purified isoenergetic experimental diets using casein and gelatin as protein sources were formulated to contain graded levels of protein (16, 20, 24, 28, 32 and 36%). Fish initially averaging 15.52±0.33g (mean±SD) were randomly distributed into the tanks (500L) as groups of 20 fish and fed to apparent satiation twice daily for 60 days. The results showed that feed consumption, feed conversion ratio, fish weight gain, specific growth rate, protein efficiency ratio and protein productive value were affected by dietary protein level (P&lt;0.05) . No significant differences were observed in proximal composition of carcass...

ABSTRACT: The aim of this study was to determine the most adequate stocking density for tambatinga during the initial grow-out phase in net pens, considering fish growth, health, and financial aspects. Three stocking densities (400, 500, and 600 fish m-3) were evaluated for 60 days in a completely randomized design (n=4). There were no significant differences among the stocking densities for growth performance parameters, but yield was higher in the density of 600 fish m-3 (3,909.43±397.79kg m-3) compared to 400 fish m-3 (2,656.43±665.45kg m-3). Glucose, hematocrit, and total plasma proteins levels did not differ among treatments. The production was economically feasible for the three stocking densities. However, the density of 600 fish m-3 showed the...

ABSTRACT In recent years, a trend has emerged to eliminate soybean meal (SBM) from rabbit diets. It was hypothesized that a dietary mixture composed of rapeseed meal (RSM), white lupine seeds (WLS) and pea seeds (PS) could be a substitute for SBM in diets for growing rabbits without compromising their growth and physiological parameters. To verify this hypothesis, selected parameters describing the growth rate of rabbits, their blood and slaughter parameters and caecum function were analyzed. The experiment was performed on ninety HYPLUS rabbits. Control group (C) animals were fed a diet containing 15% SBM. The diet administered to the first experimental group (E1) contained 7.5% SBM, 5.0% RSM, 4.0% WLS and 3.0% PS. In the diet fed to the second...
