A comparative study of artificial neural network (ANN) and multiple regression is made to predict the fat tail weight of Balouchi sheep from birth, weaning and finishing weights. A multilayer feed forward network with back propagation of error learning mechanism was used to predict the sheep body weight. The data (69 records) were randomly divided into two subsets. The first subset is the train...

previous studies have indicated that fish oil intake wi1l improve semen quality in some mammals and birds. the aim of this study was to investigate the effect of dietary fish oil on reproductive performance in ram. eight zandi rams were divided into two groups and fed either a control diet or a supplemented diet with fish oil. both of the diets were isocaloric and isonitrogenous and formulated ...

despite a shortage of animal feed in iran, cereal stubble is often underutilized due to agro-economic reasons. on the other hand, lambs fed with a conventional fattening ration deposit a considerable amount of fat; therefore, this experiment was conducted aimed at better utilization of cereal stubble and reducing the fat content of lamb carcasses. fat-tailed mehraban and ghezel ram lambs were p...

The main objective of the present investigation is to evaluate the anti-inflammatory & analgesic activity of ethanolic extract of Shirishadi polyherbal compound on rats. Shirishadi compound consist of three herbal drugs namelyShirisha (Albizzia lebbeck), Nagarmotha (Cyprus rotandus) & Kantakari (Solanum xanthocarpum).In Ayurveda (ancient Indian system of medicine) all these herbs alone or in co...

Skeletal unloading induces trabecular bone loss in loaded bones. The tail-suspended mouse model simulates conditions associated with lack of mechanical stress such as space flight for the loaded bones. In such a model, the tail supports the body weight. The forelimbs are normally loaded and the movement of its hindlimbs is free without weight bearing. Histomorphometric analyses of the murine ti...

Direct evidence has been obtained that the tail-associated lysozyme of bacteriophage T4 (tail-lysozyme) is gp5, which is a protein component of the hub of the baseplate. Tails were treated with 3 M guanidine hydrochloride containing 1% Triton X-100, and the tail-lysozyme was separated from other tail components by preparative isoelectric focusing electrophoresis as a peak with a pI of 8.4. The ...

The attachment of tail fibers to tail-fiberless T4 particles in extracts of mutant-infected cells proceeds slowly in the absence of gene product Cgp) 63, but can be stimulated up to 50-fold by its presence, supporting the view that gp63 acts catalytically to increase the rate of tail fiber attachment. The active protein has been purified about loo-fold to yield a nearly homogeneous preparation....
