| 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 < 0.05) IGF-I expression... |

| O mulateiro é uma das espécies que vêm sendo exploradas por pequenos madeireiros e produtores, de forma extensiva no Estado do Acre. A exploração é feita às margens dos rios e igarapés, onde as árvores são derrubadas, cortados os pranchões e transportados para cidades próximas. Apesar da boa qualidade da madeira, para uso múltiplo, os preços de mercado são muito baixos. É uma espécie pioneira com ocorrência próxima a praias e capoeiras. O trabalho está sendo realizado na Floresta Estadual do Antimari e na Área de Estudos da FUNTAC, no km 67 da BR 317, com os seguintes objetivos a) acompanhar o ciclo fenológico da espécie; b) estudar seu crescimento e características de ocupação em áreas de ocorrência natural; c) estudar o comportamento da espécie em... |

| 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... |

| 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... |

| 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... |

| ABSTRACT The present study was conducted to evaluate whether dietary hot pepper waste powder (HPWP) would affect the performance and small intestine histology parameters in Japanese quail chicks. A total of 160, one-day-old Japanese quail chicks were divided into 4 treatment groups of similar mean weight, comprising 4 subgroups of 10 chicks each. Chicks were fed on their basal diet supplemented by 0, 100, 200 or 400 mg/kg of dietary HPWP for each kg of starter (0 to 10 days), grower (11 to 24 days) and finisher (25 to 42 days) diets for 7 weeks. At the end of 42 days of age, 10 birds per subgroup were slaughtered and intestinal samples were taken to evaluate histomorphological analyses. The results showed that dietary HPWP supplementation did not affect... |

| ABSTRACT The present study was conducted to evaluate the effects of feeding broilers with garlic fermented by Leuconostoc citreum SK2556. A total of 250 male broiler chicks was randomly housed into 25 floor pens. Five dietary treatments with five replicates of 10 chicks each (n=50 chicks/treatment). A corn and soybean meal based diet was used as the control diet (NC). The experimental diets were formulated by mixing the basal diet either with antibiotics (10 ppm; PC) or fermented garlic (FG) at the concentrations of 0.1% (FG1), 0.3% (FG3) or 0.5% (FG5) in diets. Daily weight gain, feed intake, and feed:gain ratio were not affected by any of the dietary treatments. Average daily gain on day 21 linearly increased (p= 0.024) with increasing FG levels. The... |

| ABSTRACT This study was carried out to identify the effect of the egg shape index on the hatchability, performance, and carcass yield of Japanese quails (Coturnix coturnix Japonica ). Eggs were incubated in three groups, according to three different egg shape index (SI) values (Group SI-I: 70.00-73.85%, Group SI-II: 73.86-77.71% and Group SI-III: 77.72-81.57%). Unhatched eggs weight loss (HEWL) was correlated with the egg shape index groups (SI-I: 18.51%, SI-II: 13.34% and SI-III: 13.96%; p<0.01), but not with the initial unhatched egg weight (HIEW), hatched egg weight (HEW), or eggshell weight of unhatched eggs (HSW) (p>0.05). The live weight of female and male chicks hatched from SI-I, SI-II, and SI-III egg shape index groups were compared at weeks... |

| ABSTRACT In this study, 240 one-d-old Arbor Acres broiler chicks (160 males and 80 females) were randomly allocated in a completely randomized design with four treatments and four replicates. Broilers were fed from hatching to 28 d of age four diets: a basal diet (control), 2% red ginseng marc, 1% fermented red ginseng marc with red koji, and 2% liquid red ginseng. Growth performance and fatty acid profiles in broiler were evaluated. Supplementing diets with different types of red ginseng did have significant effects (p<0.05) on initial body weight, due to differences in the birth weights of birds, including weight gain, and mortality. However, no significant differences between the treatments (p>0.05) were found for final body weight, feed intake,... |
