The effects of the diet fat type on some biochemical, growth and semen characteristics were studied in 32 males Muscovy ducks distributed into 4 comparable experimental groups of 8 birds. During a period of 12 weeks, each of the group was randomly fed one of the rations including the control diet (T) or one diet containing either soya bean oil (S), pig fat (G) or palm oil (P). Life weight of group G was significantly (P<0.05) lower as compared to other groups. The carcass yield and percentage of liver relative to life weight was similar (P>0.05) among groups. Diet containing Pig fat induced the lowest (P<0.05) heart percentage while Soya bean oil induced the highest. The highest (P<0.05) testis proportion (0.59%) was registered in control group and the lowest (0.16%) with Palm oil which also induced the highest (P<0.05) gizzard proportion. Pig fat induced the significantly (P<0.05) higher intra testicular protein as compared to the others treatments. Control group recorded the significantly (P<0.05) lower intra hepatic protein rate as compared to the pig fat group. The intra testicular cholesterol rate remained comparable (P>0.05) among treatment groups. For the hepatic cholesterol rate, value obtained with palm oil was significantly (P<0.05) higher than that of the control group. Sperm volume induced by pig fat was significantly (P<0.05) smaller than that of other treatments groups. Semen characteristics (concentration, motility, viability and pH) were not statistically (P>0.05) different among groups. The type of dietary fat except pig fat may therefore improve growth and reproduction performance of Muscovy duck.

Abstract: (french)
L'effet du type de matière grasse alimentaire sur quelques caractéristiques biochimiques, de croissance et de la semence a été étudié sur 32 canards de Barbarie mâles repartis en 4 traitements comparables de 8 sujets. Pendant 12 semaines, chacun des traitements a reçu au hasard soit la ration témoin sans matière grasse (T), soit l'une des rations contenant l'huile de soja (S), la graisse de porc (G) ou l'huile de palme (P). Le poids vif du traitement G à la fin de l'essai a été significativement inférieur (P<0,05) à celui des trois autres traitements par ailleurs comparables (P>0,05). Le rendement carcasse et la proportion du foie par rapport au poids vif ont présenté pour chacun ces paramètres des valeurs comparables (P>0,05) entre les différents traitements. La proportion des testicules significativement (P<0,05) la plus élevée a été enregistrée avec le traitement témoin (0,59%) et la plus faible avec l'huile de palme (0,16%). Le taux de protéine intra testiculaire le plus faible (P<0,05) a été relevé avec le traitement P et le plus élevé (P<0,05) dans le traitement G. Le taux de protéine intra hépatique du traitement témoin a été plus faible (P<0,05) comparé à celui des autres traitements qui ont été par ailleurs comparables (P>0,05). Le traitement témoin a également enregistré le taux de cholestérol hépatique significativement (P<0,05) plus faible comparé au traitement à l'huile de palme. La graisse de porc (G) a induit le volume spermatique significativement (P<0,05) plus faible par rapport aux autres traitements. Cependant, les autres caractéristiques de la semence (concentration, motilité, viabilité et pH) ont été comparables (P>0,05) quel que soit le traitement. Les matières grasses autres que la graisse de porc sont suggérées pour améliorer les performances zootechniques du canard de Barbarie.
