Ad Libitum

Two basal feeds (118 and 175 g protein/kg) with similar balanced amino acid mixtures were appropriately blended to produce six experimental diets differing in protein. These were fed for six weeks to 180 broiler breeder hens (Ross 308) housed in individual cages from 26 w of age. A 13 h photoperiod was applied. Half the birds were restricted to 160 g of feed/d, whilst the others were fed ad libitum. The treatments were randomly allocated within six blocks. At the end of the six-week period the mean voluntary intake of the ad libitum-fed birds was 169 g/d whereas the intake of hens on feed restriction was 155 g/d. In spite of the range of protein intakes from 18.5 and 28.8 g/bird, no differences were observed in rate of laying between the two feeding strategies or dietary protein levels, nor were there differences in the proportions of yolk or albumen between these treatments. Egg weight, egg output and weight gain increased with protein intake as did energy retention (kJ/d) whereas heat output (kJ/d) decreased as protein intake increased. Even though dietary protein intake had no effect on rate of lay, the resultant decrease in heat output at high protein intakes suggests that this might be a useful strategy to consider for overcoming mild heat stress.Keywords: Ad libitum feeding, heat production, energy retention, egg composition

Pig growth models can be useful tools for identifying optimum management strategies for individual grower-finisher pig units, by integrating knowledge of nutrient utilization for growth and animal-environment interactions into one system. In addition, these models can be used to demonstrate basic principles of nutrient utilization for growth in the pig, to examine “what-if” scenarios, to aid in the development of pig breeding programs and to develop effective research programs. Models used in commercial pork production should represent the biology of growth in the pig and should be flexible, so that they can be focused easily on the needs and special conditions pertaining to particular growing–finishing pig units. For proper application of pig growth models in practice, pig units should be characterized reasonably accurately. This applies in particular to the upper limit to body protein deposition that pigs can achieve under practical conditions, feed intake at various stages of growth and the alternative feeding strategies that can be considered. Some illustrative examples of the commercial application of a pig growth model under Canadian conditions are provided. Key words: Pig, growth, models, application
