Genetic relationships of body composition and feed utilization traits in European whitefish (Coregonus lavaretus L.) and implications for selective breeding in fishmeal- and soybean meal-based diet environments.
Body composition traits have potential use in fish breeding programs as indicator traits for selective improvement of feed efficiency. Moreover, feed companies are increasingly replacing traditional fish meal (FM) based ingredients in feeds for carnivorous farmed fish with plant protein ingredients. Therefore, genetic relationships of composition and feed utilization traits need to be quantifie...
متن کاملThe Future of Plant Breeding
A symposium was hosted 10 to 11 Mar. 2005 at Michigan State University to discuss the future of plant breeding education at public institutions. Plant breeding remains a vibrant, multidisciplinary science characterized by its ability to reinvent itself by absorbing and utilizing novel scientific findings and technical approaches. A contemporary breeding curriculum should include hands-on experi...
متن کاملHorticultural Plant Breeding: Past Accomplishments, Future Directions
Genetic improvement of agronomic crops through breeding, which typically are marketed as commodities, are grower directed. Breeding objectives principally involve increasing yield, often based on resistance to biotic and non-biotic stress. For example improvement in hybrid maize yields have relied on increasing yield stability under high populations. In horticultural crops, breeding objectives ...
متن کاملThe effect of fishmeal supplementation of a straw-based diet on growth and calorimetric efficiency of growth in heifers.
Thirty-two 160 kg dairy heifers were used to measure the effects of increasing dietary protein content on growth and heat production. A basal diet containing (g/kg) 550 sodium hydroxide-treated straw, 220 barley, 220 sugarbeet pulp and 10 urea was offered with 0, 76 and 152 g fishmeal/kg dry matter of the basal diet (F0, F1 and F2 levels respectively). The three diets were each given at two lev...
