The Short-tailed Shearwater, Puffinus tenuirostris, is a trans-equatorial migrant, breeding in Tasmania and other parts of southeastern Australia during the Austral summer and migrating to the northern North Pacific for the Boreal summer. Juveniles, in particular, suffer considerable mortality during the migration. Body composition of juveniles and adults in terms of body mass, lipid content, p...

Aim: The present study was carried out to evaluate the nutrient digestibility of sweet sorghum stover, an unconventional roughage source in ram lambs in comparison to conventional sorghum and maize stovers. Materials and Methods: 18 Nellore ram lambs aged about 3 months (average body weight 15.65±0.10 kg) were randomly allotted to three complete rations formulated with roughage to concentrate r...

This experiment investigated the effects of increasing the dietary content of bacterial protein meal (BPM) on the protein and energy metabolism of pigs from weaning to a live weight of 80 kg. Four litters with four castrated male pigs in each litter were used. The litters were divided into two blocks according to age. One pig from each litter was fed one of the four experimental diets. Soya-bea...

This study aimed to investigate the effect of the ratio of non-fibrous carbohydrates to neutral detergent fibre (NFC/NDF) and undegraded dietary protein (UDP) on rumen fermentation and nitrogen metabolism in lambs. Four Dorper×thin-tailed Han crossbred lambs, averaging 62.3±1.9 kg of body weight and 10 mo of age, were randomly assigned to four dietary treatments of combinations of two levels of...

In this study, control (0), 50, 100, 200, 400, 800 and 1000 mg L-1 ginger essential oil (GEO) (Zingiber officinale Roscoe) was added to rumen liquid (RL). Then, the effects of GEO RL vitro gas production, organic matter digestibility (OMD), metabolisable energy (ME), fermentation parameters methane (CH4) production were examined on these samples. It determined that addition decreased in Trifoli...

Estimation of the quality of commercial diets is a topic of interest for the majority of dog owners. Recently, in a French consumer association magazine, an evaluation of eight dog commercial dry diets (from super-premium, basic-nutrition, private-label and economy brands) according to several nutritional criteria was published. The aims of the study were: (1) to evaluate the apparent digestibi...

1. In a study spanning two breeding seasons, we assessed the effect of different dietary energy and protein levels on body mass, body condition, and egg production of female ostriches. 2. During the first breeding season, groups were given diets with energy concentrations of 8.5, 9.5 and 10.5 MJ/kg dry mass (DM) metabolisable energy (ME) and protein concentrations of 135, 150 and 165 g/kg. In t...

A number of wheat samples were obtained for evaluation: for young poultry, 50 wheats (10 varieties each grown at ®ve sites) with bushel weights/thousand grain weights ranging from 69.5 to 80.0 kg/hl and 34.6 to 59.3 g, respectively; for pigs (8 different varieties each grown at 2 sites) with bushel weights/thousand grain weights ranging from 71.0 to 81.5 kg/hl and 40.9 to 56.7 g, respectively. ...

Fibre can interfere with digestibility of fat by accelerating intestinal passage or increasing chyme viscosity. Lecithin is an important emulsifier which improve digestion. The study aims to determine if fibre solubility may apparent true total tract (ATTD; TTTD) macronutrients and energy adding lecithin could digestibility. Stool quality was evaluated regarding inclusion. Eighteen adult dogs f...

This study was conducted to determine the nutritive value of soybean varieties using in vitro methods and gas production technique.In vitro gas productions and gas production kinetics of soybean variety were determined at 0, 3, 6, 12, 24, 48, 72 and 96 h incubation times. This study revealed that there were variations among five different soybean varieties in terms of chemical...
