A trial was carried out to determine the lysine requirement for starting barrows fed on ideal protein concept-based diets. Thirty-two pigs from a commercial crossbred genetic group (CCGG, BW=15.9 ± 1.4 kg) and 32 pigs from a dam line one (DLGG, BW= 14.8 ± 1.0 kg) were used. Pigs were allotted to 4 treatments with diets containing increasing levels of total lysine (0.80, 1.00, 1.20 and 1.40%). Methionine+cystine, threonine and tryptophan were adjusted according to ideal protein profile. Data from performance, plasma urea nitrogen (PUN) and carcass composition were analyzed. CCGG showed higher daily feed intake, daily weight gain, PUN and protein:fat ratio in carcass, while DLGG showed higher fat carcass content and nitrogen retention. Fat content and...

Autores: Moreira,Ivan; Fraga,Alessandro Luis; Paiano,Diovani; Oliveira,Gisele Cristina de; Scapinello,Cláudio; Martins,Elias Nunes.
The effects of increasing lysine levels on nitrogen balance of pigs fed on low protein diets were evaluated. Four treatments (diets) containing lysine levels (0.8, 1.0 1.2 and 1.4%) were applied to 12 starting (20.0 ± 1.8 kg) barrow pigs. Methionine, threonine and tryptophan were kept constant to the lysine ratio in all diets. Feces and urine were collected during a 5-day period. Nitrogen output in urine (NOU), total nitrogen output (TNO), nitrogen retention (NR), net protein utilization (NPU), biological value or feed protein (BVFP), urine urea nitrogen (UUN), and plasma urea nitrogen (PUN) were determined. PUN showed high negative correlations with BVFP (-0.84), NPU (-0.76), and NR (-0.78) and a positive correlation (0.79) to NOU. Lowest nitrogen...
