Supplementation with Vitamin B12 and Amino Acids of Chick Diets Containing Soybean or Cottonseed Meal

Cottonseed Meal for Poultry: from Research to Practical Application

“…Methionine supplementation of cottonseed meal has shown no response in some chick experiments (Grau, 1946;Machlin et al, 1952) and turkey trials (Kratzer et al, 1955), a variable response in other chick growth trials (Stephenson and Greene, 1962) and a definite growth increase in additional chick research (Arscott and Brown, 1961). Anderson (1965) reported methionine to be the second limiting amino acid in cottonseed meal.…”

“…1952;Arscott and Brown, 1961) and feed efficiency only in one experiment (Combs and Nicholson, 1962). No growth response has been obtained by supplementing cottonseed mealcontaining rations for chicks with tryptophan (Grau, 1946;Machlin et a[., 1952;Stephenson and Greene, 1962), threonine (Grau, 1946) or tyrosine (Machlin et al, 1952).…”

“…Increased gains have resulted when cottonseed meal-containing rations have been supplemented with vitamin Biz (Blaylock and Richardson, 1950;Sherwood and Couch, 1950;Patrick, 1953), antibiotics such as penicillin and aureomycin (Patrick, 1953) or combinations of antibiotics and vitamin Biz (Lewis and Sanford, 1953 ;Machlin et al, 1952). On the other hand, Machlin et al.…”

Use of Equivalent Levels of Antibiotic and Vitamin B12 Supplements With Cottonseed and Soybean Oil Meals in Chick Diets

“…Richardson and Blaylock (1950) reported that cottonseed meal supplemented with lysine and vitamin B12 supported a rate of growth comparable to that obtained when soybean meal was used as a source of protein in a chick ration, but resulted in inferior rate of growth when vitamin B12 and lysine were omitted. Machlin, Denton and Bird (1952) obtained an increase in growth by supplementing a corn-cottonseed meal basal diet with an aureomycin fermentation product containing B12 and aureomycin. They also reported that the addition of this product to a lysine-supplemented basal diet produced growth superior to that obtained from a good commercial broiler ration.…”

Corn Glutelin Protein as a Source of Amino Acids for the Growing Chick

“…The most commonly used material of this type is soybean oil meal, although its use in poultry diets necessitates the addition of supplements to augment its deficiency in sulphur containing amino acids (Bird and Mattingly, 1945;Clandinin et al, 1946;Gerry et al, 1948;Milligan et al, 1951;and Machlin et al, 1952). The most commonly used material of this type is soybean oil meal, although its use in poultry diets necessitates the addition of supplements to augment its deficiency in sulphur containing amino acids (Bird and Mattingly, 1945;Clandinin et al, 1946;Gerry et al, 1948;Milligan et al, 1951;and Machlin et al, 1952).…”
