The Value of Fish Solubles and a Vitamin B12-Antibiotic Supplement in Chicken and Turkey Mash Mixtures Containing Ten Percent Meat Scraps

The Influence on Palatability of Certain Grain Combinations, Fish Solubles and a Vitamin B12-Aureomycin Supplement in Poultry Rations ,

“…Although the use of fish solubles did not appear to improve market grade for these turkeys, there was a considerable stimulus on growth rate, feed efficiency and livability with an improved market weight for these birds over the controls (Halbrook et al, 1953). With the higher palatability scores combined with these other favorable influences upon birds receiving fish solubles, it would seem that fish solubles are a good adjunct in turkey rations.…”

“…Halbrook et al (1953) reported a slight favorable influence of fish solubles added to the rations of S. C. White Leghorns in regard to temporarily increased growth rate, feed efficiency, and an improvement of market grade.…”

“…Swickard et al (1953) did not find any significant differences between mean scores for aureomycin-fed turkeys receiving one-half as much aureomycin as reported in this experiment and controls, for light or dark meat or skin, or any quality factor for turkeys. Halbrook et al (1953) reported that advantages in the Bi 2 -aureomycin supplemented birds were limited to a slightly increased growth rate and improved liability during the early growing period with no over-all market improvement of the supplemented as compared to the nonsupplemented birds. The palatability studies on these turkeys would further indicate that little if any benefit may be derived from the use of this supplement in the ration of Broad Breasted Bronze turkeys.…”

“…Halbrook et al (1953) indicated that the advantages of a vitamin Bi 2 -aureomycin supplement in the rations of S. C. White Leghorn broilers included increased growth and feed efficiency, improved livability, and quite noticeably improved…”

Value of Antibiotics in Rations for Egg Production

“…Carver et al (1951) found that neither aureomycin nor terramycin improved egg production when included in an all-plant diet or one containing fish meal. Halbrook and Beeckler (1951) supplemented a laying ration containing animal proteins with a vitamin Bi 2 -antibiotic supplement and obtained no consistent improvement in egg production or livability. Similar results were reported by Sunde et al (1951).…”
