The Effect of Vitamin E, Dehydrated Alfalfa Meal and Condensed Fish Solubles Upon Hatchability of Eggs from Broad Breasted Bronze Hens Maintained on Litter

The Effect of Dehydrated Alfalfa Meal, Dried Brewers Yeast and Condensed Fish Solubles on the Reproductive Performance of Turkeys

“…These data indicate that unidentified factors found in dehydrated alfalfa meal, condensed fish solubles and dried brewers yeast are necessary for the continued maintenance of the hatchability of turkey eggs after the 12 th week of the laying period. These data are in agreement with the earlier reports by Atkinson et al (1955b) and Ferguson et al (1956).…”

“…This suggests the possibility that condensed fish solubles contains an unidentified factor which reduces the embryonic mortality during the last week of the incubation period. Although not statistically significant, these data are in agreement with the earlier reports of Atkinson et al (1955b) and Ferguson et al (1956). The need for further study is indicated at higher levels of condensed fish solubles.…”

“…The level of pantothenic acid supplied by the basal diet was in excess of the level reported by Kratzer et al (1955) to be necessary for maintaining optimum hatchability of turkey eggs. The level of vitamin E used in this study was the same as that reported by Jensen et al (1953), Atkinson and Couch (1954), Atkinson et al (1955a, b), Scott and Nelson (1955), and Ferguson et al (1956). Supplements to the basal diet were made as indicated in Table 1.…”

“…Earlier reports have indicated that the decline in hatchability can be delayed by supplementing the diet with sources of unidentified factors. Some of the supplements reported to increase hatchability are pork liver meal, desiccated meat meal, fish meal, dried buttermilk, dried skimmilk, meat scraps, dehydrated alfalfa meal, distillers dried solubles, dried whey, and liver "L" (Nestler et al, 1936;Dickens et al, 1941;Atkinson et al, 1951Atkinson et al, , 1953Atkinson et al, , 1955bCouch et al, 1954;and Ferguson et al, 1956). The fat soluble vitamins E and D, as well as pantothenic acid, have been shown to be necessary in the maintenance of hatchability (Stadelman et al, 1950;Jensen et al, 1953;Jensen, 1953;Jensen et al, 1956;Atkinson and Couch, 1954;Atkinson et al, 1955a, b;Scott and Nelson, 1955;Kratzer etal., 1955;and Ferguson et al, 1956).…”

The Effect of Dehydrated Alfalfa Meal, Dried Brewers Yeast, Condensed Fish Solubles and Fermentation Residue on the Reproductive Performance of Turkeys

“…Some of the supplements which have been reported to contain the unidentified factor(s) required for normal hatchability are pork liver meal, meat meal, fish meal, dried buttermilk, dried skim milk, meat scraps, dehydrated alfalfa meal, distillers dried solubles, dried whey, condensed fish solubles, and liver "L" (Nestler et al, 1936;Dickens et al, 1941;Atkinson et al, 1951Atkinson et al, , 1953Atkinson et al, , 1955bCouch et al, 1954;Ferguson et al, 1956;and Feldman et al, 1957).…”
