Two experiments were conducted to determine the nutritive value of copra meal for grower and finisher pigs (40–95 kg). 21 The apparent nutrient digestibility of copra meal, when included at 200 and 400 g kg in the diet of both the grower and finisher pig, was determined in experiment 1. In experiment 2, productive performance was determined in group fed pigs 21 (n 5 360) offered diets ad libitu...

A growth performance and carcass evaluation study was conducted to determine the maximal inclusion rate of corn distillers dried grain with solubles (DDGS) in grower-finisher pig diets when formulated on a total AA basis. A total of 240 (28.4 +/- 0.8 kg of BW) crossbred pigs [(Yorkshire x Landrace) x Duroc] were allotted randomly within sex and weight outcome groups to 1 of 24 pens. Pens were a...

Two experiments were conducted to investigate the effect of dietary supplementation of Bacillus, Saccharomyces and lactic acid bacteria (LAB) on performance and nutrient digestibility in grower and finisher pigs. In Exp. 1, 80 pigs (32 females and 48 males), 28.7±0.9 kg body weight (BW), were randomly divided into 4 treatment groups balanced for sex and weight (5 pigs per pen, 4 pens per treatm...

Two replicate experiments were done to investigate if special diets provided to broilers in their last phase of life could reduce the negative effects of feed withdrawal and transport without an increased content of the digestive tract. In each experiment, 240 broilers were used. The experiments consisted of 2 interventions: the feed intervention and the transport intervention. The feed interve...

The Dutch sugar industry and sugarbeet research initiated the project SUSY (Speeding Up Sugar Yield) as a reaction to the reform of the European Union sugar regime. The project was aimed at softening the reform’s impact on grower income by improving their knowledge on raising sugar yield and identifying possible cost savings. From each sugarbeet growing region in The Netherlands, 26 pairs of ‘t...

The paper describes a simplified dynamic model of a greenhouse tomato crop, and the optimal control problem related to the seasonal benefit of the grower. A HJB formalism is used and the explicit form of the Krotov–Bellman function is obtained for different growth stages. Simulation results are shown. © 2009 Elsevier Ltd. All rights reserved.

Data from a 3-yr feeding trial of crossbred steers (n = 331) were used to examine the relationship between feeding behavior traits and feed efficiency in steers fed grower and finisher diets, successively. There were 2 feeding periods each year whereby the steers were fed a grower diet in the first feeding period (P1) and a finisher diet in the second feeding period (P2). Each feeding period la...
