No adverse effect of a parental low protein/high carbohydrate diet on their offspring, in rainbow trout (liver)

Project description:In rainbow trout (Oncorhynchus mykiss), the effect of a paternal and a maternal "high carbohydrate/low protein" diet was assessed on progeny. To this purpose, two-year old males and females rainbow trout were fed either a control diet or a "high carbohydrate/low protein" diet for an entire reproductive cycle for females and for 5 months for males. Crossed-fertilizations were carried out in order to obtain 4 groups of offspring. Offspring were fed with a commercial diet until they reached a market size. At this stage, hepatic transcriptomes were compared to detect any impact of the parental diet on offspring metabolism.

No adverse effect of a parental low protein/high carbohydrate diet on their offspring, in rainbow trout (muscle)

Project description:In rainbow trout (Oncorhynchus mykiss), the effect of a paternal and a maternal high carbohydrate-low protein diet was assessed on progeny at long term. To this purpose, two-year old male and female rainbow trout were fed either a control diet or a high carbohydrate/low protein diet for an entire reproductive cycle for females and for 5 months for males. Crossed-fertilizations were carried out in order to obtain 4 groups of offspring. Offspring were fed with a commercial diet until they reached a market size. At this stage, muscle transcriptomes were analysed to detect any effect of the parental diet on offspring metabolism.

Modulation of energy metabolism and epigenetic landscape in rainbow trout fry by a parental low protein/high carbohydrate diet

Project description:In rainbow trout (Oncorhynchus mykiss), the effect of a paternal and a maternal high carbohydrate/low protein diet was assessed on progeny. To this purpose, two-year old males and females rainbow trout were fed either a control diet or a high carbohydrate/low protein diet for an entire reproductive cycle for females and for 5 months for males. Crossed-fertilizations were carried out in order to obtain 4 groups of offspring. Before the first feeding, whole fry transcriptomes were compared to detect any impact of the parental diet on offspring metabolism.

Programming of the hepatic lipid metabolism via a parental high carbohydrate low protein diet in rainbow trout

Project description:In rainbow trout (Oncorhynchus mykiss), the effect of a paternal and a maternal high carbohydrate-low protein diet was assessed on progeny at long term. To this purpose, two-year old male and female rainbow trout were fed either a control diet or a high carbohydrate/low protein diet for an entire reproductive cycle for females and for 5 months for males. Crossed-fertilizations were carried out in order to obtain 4 groups of offspring. Offspring were fed with a commercial diet until they reached a market size and were then challenged with a complete plant-based diet for 3 months. After the challenge, hepatic transcriptomes were analysed to detect any effect of the parental diet on offspring metabolism.

No adverse effect of a maternal high carbohydrate diet on their offspring, in rainbow trout (<i>Oncorhynchus mykiss</i>).

Project description:In order to develop a sustainable salmonid aquaculture, it is essential to continue to reduce the use of the protein-rich fishmeal. One promising solution to do so is the use of plant-derived carbohydrates in diet destined to broodstock. However, in mammals, the reduction of protein content (replaced by carbohydrates) in parental diet is known to have strong adverse effects on offspring phenotypes and metabolism. For the first time, the effect of a paternal and a maternal high carbohydrate-low protein diet was assessed on progeny at long term in the rainbow trout. A 30% protein diminution in both males and females broodstock diet during 10 month and 5 months, respectively, did not trigger adverse consequences on their offspring. At the molecular level, offspring transcriptomes were not significantly altered, emphasizing no effect on metabolism. Tenuous differences in the biochemical composition of the liver and the viscera were observed. The recorded effects remained in the normal range of value and accordingly offspring growth were not negatively affected over the long term. Overall, we demonstrated here that a 30% protein diminution during gametogenesis is feasible, confirming the possibility to increase the proportion of plant-derived carbohydrates in female broodstock diets to replace fishmeal proteins.
