Effect of Supplemental Choline on Performance of Starting, Growing and Finishing Pigs: a Cooperative Regional Study
نویسنده
چکیده
Severn hundred pigs were used in experiments at eight stations to evaluate the efficacy of supplemental dietary choline during the starting, growing and finishing production phases. Increasing levels of choline chloride were added to corn-soy-lysine basal diets formulated to contain 15% crude protein (.95% lysine), 13% crude protein, (.75% lysine) and 11% crude protein (.55% lysine) for the starting, growing and finishing production phases, respectively. The addition of choline did not produce a growth response during any stage of production. Likewise, feed to gain ratios did not differ although there was a trend for choline supplementation to impair feed conversion during the growing phase. It is concluded that added choline has no beneficial effect on performance in corn-soy-lysine diets fed to pigs. (

Excess supplemental choline for swine.
Seven experiments were conducted with 280 crossbred pigs to investigate the effect of excess choline on rate and efficiency of gain of weanling, growing and finishing swine Choline additions were made to a conventional corn-soybean meal diet. Daily gain of weanling pigs was reduced slightly by 6,000 ppm excess choline compared with 0, 500, 1,000, 2,000 or 4,000 ppm excess choline. Excess supple...

A genetically modified corn hybrid homozygous for the lpa1 allele, containing low phytate (LP), and its nearly isogenic equivalent hybrid (normal) were compared in two experiments with growing-finishing swine. In Exp. 1, 210 barrows (27 kg) were allotted to one of six dietary treatments with two corn hybrids (LP and normal) and three P feeding regimens. There were five replicate pens (seven pig...
