BAUERSFELD and SCARES: FISH SOLUBLES 



Table 4. — Experiments II and III. Weight gains of lambs fed either 

 control milk replacer rations or those containing fish solubles and soy flour. 



throug-hout the entire experiment which was 

 terminated after 28 days. 



Table 4 shows the results of this experiment. 

 The average daily weight gains of lambs fed the 

 control ration and those fed the fish solubles 

 plus milk products ration were 200 g-/day and 

 100 g/day, respectively. The combined results 

 indicate that the ration containing 15^r freeze- 

 dried menhaden solubles only produced a 58 ''f 

 growth response as compared to that of the con- 

 trol ration. At the 15 ''r level of incorporation, 

 dried fish solubles will not efl'ectively replace the 

 DSM protein. It should be noted that this level 

 of incorporation corresponds to 30 '^r on an "as 

 is" basis (before freeze drying) which is an ex- 

 tremely high feeding level for fish solubles. 



The College Park Laboratory is continuing to 

 study the feasibility of using fish proteins, such 

 as partially hydrolyzed press cake, defatted fish 

 meal, and lower grade forms of FPC as substi- 

 tutes for milk products in liquid rations for neo- 

 natal animals. 



CONCLUSIONS 



The data indicate that a higher quality pro- 

 tein than that in fish solubles is necessary in 

 order to incorporate significant quantities of fish 

 protein in milk replacer rations.
