This study was conducted to determine whether early age feed restriction improves heat tolerance in female broiler chickens. Chicks were brooded for 3 wk and then maintained at 24+/-1 C. On Day 0, chicks were assigned to one of four feeding regimens; each regimen was applied to four cages of chicks. The feeding regimens were 1) ad libitum feeding (ALF); 2) 40% feed restriction at 4, 5, and 6 d ...

Two experiments involving 288 pigs were conducted to determine the effects of shortterm feed restriction during the growing period on average daily gain (ADG), average daily feed consumption, feed required/unit of gain (F/G), age at 100 kg and average backfat depth at 100 kg. Pigs were fed 100, 85 or 70% of ad libitum consumption for 2or 4-wk periods in Exp. 1 and 100 or 85% for 2or 4-wk period...

This contribution deals with the optimization of the design of reactive distillation columns by using a memetic algorithm (MA) which is a combination of an evolution strategy (ES) and a mathematical programming (MP) solver. The focus of this paper is on the restriction on the number of feed trays that introduces discrete variables into the problem formulation. The optimization of the number and...

Effect of Qualitative Feed Restriction and Duration its Application on Performance, Blood Biochemical Parameters, Carcass Characteristics Broiler Chickens

The purpose of this study was to determine if the efficiency of energy retention in pregnant cows was dependent on the time during the pregnancy that feed was offered. Our hypothesis was that restricting feed intake during the second trimester of gestation and providing the saved feed during the third trimester was less energetically efficient than providing the feed during the second trimester...
