Shirbot (Barbus grypus) as a species with high potential for aquaculture development recently propagated artificially in South Iran Aquaculture Research Center to extend the species diversity in polyculture system. To provide an effective economic diet for this species 9 experimental diets containing three crude protein levels (250, 300, and 350 g kg -1) and three metabolizable energy levels ...

a study was conducted to evaluate the effect of feeding different levels of protein to black baladi breed kids. weanling baladi kids (n=18; 75 to 90 days old) were selected and individually housed at our experimental farm. kids were divided randomly to one of the three treatments for 12 weeks. the three dietary treatments were: t1: control ration, formulated according to nrc to cover the protei...

The objectives of this experiment were to evaluate the effects of dietary protein supplementation in lactating dairy ewe’s diets on milk coagulation properties. Milk samples (n=126) were analyzed to assess the source of variation for rennet coagulation ability at the 6th (RCA6) and 12th hour (RCA12), milk clotting time (MCT, s) and an index of milk clotting time (IMCT, %). In addition, data wer...

A 50-day feeding trial was conducted to evaluate the effects of yeast nucleotide in diets on growth performance, serum immune indices and muscle composition of Ancherythroculter nigrocauda (mean initial body weight, 23.30±0.59 g). Seven isonitrogenous (approximately 42.76% crude protein) and isoenergetic (17.43 KJ g−1 gross energy) experimental diets with varying levels of yeast nucleotide (0[c...

This study was conducted to investigate the effects of partial replacement of dietary fish meal with soybean meal (SBM) on some blood and serum parameters of Beluga (Huso huso) juveniles. Three isonitrogenic and isoenergetic diets, as SBM1 (Soybean meal protein (SBP): Fishmeal Protein (FP) =1:3), SBM2 (SBP: FP = 2: 3) and SBM3 (SBP: FP =1: 1) were fed to triplicate groups of fish. After 8 weeks...

The Acehnese mahseer, locally known as keureling, Tor tambra is one of the highest economically valued freshwater fishes found in Aceh waters. The culture of T. tambra was initiated in Aceh Province, Indonesia more than five years ago. However, the growth rate in captivity has been low, probably due to feeding problems. Hence, the objective of the present study was to evaluate the optimum level...
