Understanding the Mechanisms that Determine Feed Conversion Ratio in Chinook Salmon – Physiological and Behavioural Aspects
… production costs can be reduced by improving feed conversion ratio (FCR), the ratio of feed intake to weight gain. The aim of this thesis was to identify key factors that influence individual FCR variation in Chinook salmon (Oncorhynchus tshawytscha). Feed efficient and inefficient Chinook …

Effect of amino acids and vitamin D3 on performance and biological responses in poultry
… 153.2 mg/d for egg production and 140.4 mg/d for feed conversion ratio using a linear broken line model. For valine, the requirement was highest for egg mass, 597.3 mg/d, followed by egg production, 591.9 mg/d and feed conversion ratio (FCR), 500.5 mg/d. The lysine requirement of young chicks was …

Performance of broiler chickens fed Pearl Millet as an energy source and Acacia Karroo leaf meal as an additive.
… Poultry Industries and raised on a two phase feeding regime (i.e. starter for 3 weeks and finisher for 4 weeks). During the finisher phase they were fed different treatment diets. In the first trial the treatment diets were formulated such that maize was replaced with pearl millet at levels of …

Evaluation of feedlot feed efficiency relationships as well as genetic and phenotypic performance, carcass, and economic outcomes
Several feed efficiency values have recently been proposed including: feed conversion ratio in terms of feed:gain (FCR), residual feed intake (RFI), and residual BW gain (RG), and residual intake and BW gain (RIG). These all have production efficiency potential since they include feed intake inputs …

Aquaculture of Pacu (Piaractus mesopotamicus) and a Comparison of its Quality: Microbiological, Sensory, and Proximate Composition
… and color were also determined. Protein concentration significantly influenced the weights, lengths, specific growth rate, feed conversion ratio, and protein efficiency ratio (p < 0.05). Diet insignificantly influenced the processing yields (p > 0.05). The moisture, protein and total lipid …

Impact of Dietary Beta-glucan Supplementation on Performance and Immune Response of Broiler Chickens During Challenge
… plant species. The first study evaluated the feeding effects of algae- derived -glucans on performance and responses of broilers during a coccidiosis challenge. Cobb 500 broilers (n=1280) were fed a control diet, control supplemented with 150 g/MT Algamune (BG), 100 g/MT Algamune ZPC (BGZn), …
