1303 - Fecundity in Relation to Stamina. — dunnigliff (jun.) a. a., in The Agricultural 



Gazette of New South Wales, Vol. XXVII, No. 7, pp. 507-510, Sydney, July 191 6. 



The danger signal has been raised by more or less authoritative critics 

 in various parts of the world that striving for higher and higher egg 

 production, and the breeding from hens of great fecundity, can only result 

 in degeneration of the constitution of the stock and consequent disaster 

 to the breeder. Egg laying competitions have been pointed out as exer- 

 cising a dangerous influence in this direction. In New South Wales how- 

 ever where these competitions have been in progress longer than in any 

 other part ot the world there is no evidence of loss of stamina in very pro- 

 lific birds. The attainments of high records in this country has never 

 been subordinated to practical and utilitarian considerations, restrictions 

 having always existed with regard to quality.size of eggs, and weight of pullets 



It is instructive to trace the results of breeding from hens that have 

 put up high records in competitions. For instance, the pen of White 

 Leghorns which won the second two-years' test with 1474 and 1150 eggs 

 in the first and second years respectively and the pen which won the fourth 

 two-years' test with 1324 and 1045 eggs both belonged to the same owner 

 and proved entirely satisfactory as breeders both as regards fertility and 

 constitutional vigour of the progeny. Another example is the White 

 Leghorn hens which won the 1912-1913 competition with 1461 eggs and 

 which were used later with other birds of the same stock in the single pen 

 test of 1914-1915 when they achieved a world's record. The four best 

 hens in that group had individual records of 267, 270, 270,288 eggs, yet 

 when used afterwards for breeding, they gave no evidence of having suf- 

 fered constitutionally from the strain of the great production. 



The available evidence warrants the conclusion that a hen is not to 

 be regarded as a doubtful transmitter of stamina to her progeny because 

 she is the possessor of the faculty of fecundity in a high degree. The 200 

 egg hen has now become a commonplace in Australia and there seems no 

 reason why it should not be eventually replaced by strains producing 250 

 eggs 01 even more.
