The nutrient profile of zero-tannin faba bean and its effects on performance and
\ncarcass characteristics of grower-finisher pigs was investigated. In exp. 1, chemical characteristics were analyzed. Faba
\nbean contained (as fed) 27.5% crude protein (CP), 1.75% lysine, 0.88% threonine, and 0.21% methionine. Twelve 55-kg
\nbarrows were fitted with an ileal cannula and fed twice daily at 3\u0002maintenance either a 96% faba bean diet or a 62% faba
\nbean diet containing cornstarch to measure apparent total tract energy and ileal amino acid (AA) digestibility, respectively,
\nand calculate standardized ileal digestible (SID) AA and net energy (NE) content. After a 6-d acclimation, faeces were
\ncollected for 2 d and ileal digesta for 2 d. Apparent total tract energy digestibility, and digestible energy and NE content
\nwere 88.5%, and 3.47 and 2.27 Mcal kg-1 (as fed), respectively. Apparent ileal digestibility was 85.9, 76.1, and 74.1%, and
\nSID AA content was 1.54, 0.70, and 0.16% (as fed), for lysine, threonine, and methionine, respectively. In exp. 2, 100
\ngrower pigs in 20 pens were fed either a soybean or faba bean-based diet regimen from 35 to 115 kg. Diets were formulated
\nto equal NE and SID [Grower (35 to 60 kg), 2.40\/3.95; Finisher 1 (60 to 90 kg), gilts 2.38\/3.15, barrows 2.38\/2.76; Finisher
\n2 (90 to 115 kg), gilts 2.38\/2.92, barrows 2.35\/2.55; Mcal kg-1 NE\/g SID lysine Mcal-1 NE, respectively] using determined
\nNE and SID values for faba bean. Pigs were weighed, feed intake was measured, and carcass measurements were obtained.
\nFrom 35 to 115 kg, average daily feed intake (ADFI; 2.58 and 2.56 kg d-1, respectively) and gain (0.96 and 0.98 kg d-1)
\ndid not differ between faba bean and soybean meal. Feed efficiency was 0.02 higher for soybean meal than for faba bean in
\nthe Grower phase (P<0.05). At slaughter, back fat thickness did not differ; however, loin depth was 4.0 mm thicker for\nsoybean meal than for faba bean (P<0.05). In summary, zero-tannin faba bean has an attractive nutrient profile and does\nnot alter ADFI or average daily gain (ADG) of grower-finisher pigs at inclusion rates up to 30%. The reduced feed\nefficiency in the Grower phase and reduced lean thickness for pigs fed faba bean indicate that dietary AA supply might\nhave been limiting for the faba bean diets early in the study. In conclusion, the zero-tannin faba bean is a worthwhile\nenergy and protein feedstuff to consider in swine feed formulation.\n<\/p>\n","protected":false},"excerpt":{"rendered":"
