“…Pesti et al (48) fed broilers a basal diet with no choline and 4.3 g/kg methionine and found high incidence of perosis when the diet was supplemented with 150-600 mg choline/kg. According to Fritz et al (49) , 1900 mg choline/kg of diet are required to prevent that disorder. On the other hand, a study demonstrated that 450 mg choline/kg can dramatically reduce perosis (47) in broilers, and Ryu et al (50) , using a diet containing 750 mg choline/kg did not observe any signs of perosis in broilers up to 18 d of age.…”

Two experiments were carried out to evaluate the bioequivalence of a commercial phosphatidylcholine source (Biocholine™) as an alternative to choline chloride and the choline requirements of broilers of a fast-growth strain. In Experiment I, 672 broilers were fed four Biocholine™ levels (0, 100, 200, or 300 mg/kg) and three choline levels (200, 400, or 600 mg/kg) supplied as choline chloride between 4 and 28 days (d) of age. In Experiment II, 462 broilers received diets supplemented with 0, 200, 400, 600 or 800 mg/kg choline as choline chloride. In both experiments, diets were based on white rice, soybean meal, and corn gluten. In Experiment I, birds fed choline chloride presented higher feed intake than those fed Biocholine™. Both choline supplements linearly improved feed conversion ratio (FCR) between 15 and 28 d, but the curves presented different slopes, showing that one unit (U) of Biocholine™ was equivalent to 2.52 U of choline supplied as choline chloride. In Experiment II, the supplementation of choline had a quadratic effect on weight gain (WG) but did not affect FCR. Choline requirements for WG were determined as 778, 632, and 645 mg/kg for 1-7, 1-35, and 1-42 d of age, respectively.

“…In contrast, chicks and turkey poults suffer perosis as already mentioned. Hegsted et al (1941), Fritz et al (1967) and Lipstein et al (1977) did not find fatty livers in chicks deficient in choline. Although supplementation with choline of laying diets almost devoid in this vitamin has reduced the lipid content of the liver in layers (Nesheim et al, 1971;March, 1981), symptoms of deficiency of choline are difficult to induce in layers (Nesheim et al, 1971).…”

“…A choline deficiency in mammals results in fatty livers. However, a choline deficiency in chicks does not necessarily result in fatty livers (Hegsted et al, 1941;Fritz et al, 1967;Lipstein et al, 1977). Although Nesheim et al (1971) found it difficult to produce a deficiency of choline in laying hens, there is general agreement among the different reports in the literature that supplementary choline decreases the liver fat content in laying hens.…”

Choline Supplementation in the Diets of Aged White Leghorn Hens Grouped According to Body Weight

et al. 1983

A randomized block design experiment was conducted to determine if aged layers require supplemental choline when fed practical corn-soy diets adequate in methionine. Hisex hens (50 weeks old) were divided into four body weight groups containing 120 hens each. Six experimental treatments were prepared by addition of choline to a corn-soy basal diet at 0, 55, 110, 220, 440, and 880 mg/kg of diet. Each diet was fed to four replicates of 5 hens each within each body weight group. The nutrient content in the basal diet formulated for each body weight group was adjusted depending on daily feed intake. The experiment was conducted for four 28-day periods (January 21 to May 13). Hen-day egg production, feed conversion, egg specific gravity, and egg weight did not differ significantly for any level of choline supplementation. Liver lipid content was significantly different at no supplemental choline in extra heavy birds. Results of this experiment support the conclusion that, regardless of body weight, aged laying hens required very little, if any, supplemental choline when they are fed a corn-soy practical diet containing adequate methionine.
