The effects of ad libitum and restricted feeding on Yorkshire pigs selected for reduced residual feed intake
Residual feed intake (RFI), defined as the differences between observed and expected feed intake based on growth and backfat, has been used to select for improved feed efficiency in beef cattle, poultry, and now swine. However, little is known about the main biological factors that contribute to the variation in RFI in swine. The objectives of the experiments in this thesis were to compare the ...
متن کاملFeed intake of sheep when allowed ad libitum access to feed in methane respiration chambers.
The patterns of feed intake when animals are allowed ad libitum access to feed in a respiration chamber is not known, nor are the potential effects of the artificial environment of chambers on voluntary feed intake. The objectives of the study were to describe the pattern of hourly feed intake of sheep when fed for ad libitum intake in respiration chambers and determine the repeatability of thi...
متن کاملAd libitum Pasture Feeding in Late Pregnancy Does Not Improve the Performance of Twin-bearing Ewes and Their Lambs
The present study evaluated the effect of controlled ryegrass-white clover herbage availability from day 128 until day 142 of pregnancy in comparison to unrestricted availability, on the performance of twin-bearing ewes of varying body condition score (BCS; 2.0, 2.5, or 3.0) and their lambs. It was hypothesised that under conditions of controlled herbage availability, the performance of lambs b...

متن کاملSow factors affecting voluntary feed intake during lactation
Genetic and environmental changes during the last few decades have resulted in higher milk production and maintenance costs of lactating sows, leading to increased energy requirements, whereas the amount of body fat reserves of, in particular, young immature sows have decreased and voluntary feed intake may have decreased. As a consequence, present voluntary feed intake of sows during lactation...
