in this study the mixture of commercial and autochthonous bacillus subtilis and bacillus licheniformis isolated from gut of huso huso fingerling were used for enhancement of body composition and feeding parameters of whiteleg shrimp (litopenaeus vannamei). the experiment was carried out in completely randomized design. three replicates for each treatments and control group were used. the post l...

This study investigates the effects of dietary lipid sources on the growth and reproductive performance of Nile tilapia over three consecutive spawnings. Fish were reared using three experimental diets, with the goal of replacing dietary fish oil with palm oil. Three experimental diets and a commercial   trout diet was used as the control. The effect of dietary lipid on the growth performance, ...

This study investigated the effect of Rumex Sc (commercial product which includes of Saccharomyces cervisiae, saponin and essential oils) on rumen fermentation, blood glucose, urea, milk yield and milk composition. Animals were offered a basal diet containing alfalfa hay (15.5%), corn silage (24%), beet pulp (7%) and concentrate (53.5%). Additionally, Rumex Sc was included in the experimental d...

Conventional catfish culture in Ogan Ilir (OI) have not optimal production, it can be increased by biofloc and aquaponics with local swamp bacteria as a starter. The purpose of this study was to apply technology combination aquaponic-biofloc increase the productivity (Clarias sp.) rearing. used two ponds, circular pond combined aquaponic (biofloqua) for months. results specific growth rate fish...

Gastrointestinal nematode (GIN) parasitism is the greatest threat to economic sheep and goat production in the southern USA, and there is widespread prevalence of GIN resistance to broad-spectrum anthelmintics in this region. A natural alternative for controlling GIN in small ruminants is feeding hay of sericea lespedeza [SL, Lespedeza cuneata (Dum.-Cours. G. Don)], a perennial warm-season legu...

Juvenile gilthead sea bream (initial body weight ca. 100 g) were reared in an indoor flow through marine water system for 1 year. Fish were fed two isoenergetic [19.2 kJ g dry matter (DM)] and isoproteic (426 g kg DM) diets either based on fish meal (diet FM) or on a mixture of plant protein sources (diet PP), replacing 75% of fish meal protein. The growth trial was conducted in duplicate, two ...

We have been studied the effect of two diets one the growth of the Helix aspersa Müller during the juvenile stage under laboratory conditions. Diet I consists of commercial layer’s mash. We used ten lots of forty animals of 0.34 + 0.05 g, assigning five to each diet and keep them during the 6 first weeks of life in the laboratory conditions described by Perea et al. (2003) and García et al. (20...

The effects of diet on the histochemical composition of intestinal mucosubstances and the morphology of the villi and crypts were investigated by comparing the data of germ free and conventionally maintained rats fed either a purified diet or a commercial diet. The influence of intestinal microflora was evaluated by comparing the germ free rats and those harbouring either a conventional rat flo...

OBJECTIVE The variety of methodologies used to investigate ovariectomized female rats shows different results, which makes a clinical application of these results difficult. The purpose of this work was to evaluate the effect of masticatory effort reduction and of low-calcium diet on maxillary bone turnover of ovariectomized female rats. STUDY DESIGN Eighty-four female rats were divided into ...
