Detecting QTL for feed intake traits and other performance traits in growing pigs in a Piétrain-Large White backcross.
Knowing the large difference in daily feed intake (DFI) between Large White (LW) and Piétrain (PI) growing pigs, a backcross (BC) population has been set up to map QTL that could be used in marker assisted selection strategies. LW × PI boars were mated with sows from two LW lines to produce 16 sire families. A total of 717 BC progeny were fed ad libitum from 30 to 108 kg BW using single-place e...
متن کاملVoluntary feed intake and feeding behaviour of group-housed growing pigs are affected by ambient temperature and body
́ The effect of ambient temperature on individual feeding behaviour was studied in six groups of Pietrain 3 Large White barrows. In experiment 1 (two groups), ambient temperature varied in a cyclic way from 22 to 128C and 12 to 228C with three or four consecutive days at each of the following temperatures: 22, 19, 16, 14 or 128C. Similarly, in experiment 2 (two groups), temperature varied from 1...
متن کاملFeed intake pattern of group-housed growing-finishing pigs monitored using a computerized feed intake recording system.
The feed intake pattern and growth performance of boars, barrows, and gilts fed diets differing in lysine and protein content were measured on 120 crossbred pigs from 27 (SD 3.7) to 81.5 (SD 9.2) kg live weight. The pigs were housed in eight mixed-sex groups with five pigs of each sex in each group. They were fed from an electronic feed station that recorded individual meal sizes and the time a...
متن کاملFeed intake in group housed pigs – considerations for breeding programs
Feed costs account for a large proportion of the costs of pig production representing usually around 50% of the total costs (Aranda and Cleary, 2001). in the Australian pig industry this proportion has been much higher recently due to the shortage of feed resulting from the extensive drought. Selection for feed efficiency is always an important topic, independent of the current drought situatio...
متن کاملEffects of sweeteners on individual feed intake characteristics and performance in group-housed weanling pigs.
To assess the effects of 2 high intensity sodium saccharine-based sweeteners on individual feed intake characteristics and performance of group-housed weaned pigs, one hundred ninety-eight 26-d-old weanling pigs were given ad libitum access to 3 dietary treatments containing: no additional sweetener (control), 150 mg of sweetener (Sucram C-150)/kg, or 150 mg of sweetener (Sucram 3D)/kg. At wean...
