“…Some experiments (Halbersleben and Mussehl, 1922;Upp, 1928;Godfrey et al, 1953) indicated that the influence of egg size on chicken weight disappeared as early as two to four weeks after hatching. But our results were close to those of Skoglund and Tomhave (1949), Wiley (1950), and Kosin et al (1952). Although the growth curves in Fi groups distributed additively between parents (NH and WL), after five weeks, they rather inclined to grow closer to the larger New Hampshires.…”

The Effect of Egg Weight on Eight-Week Body Weight of Normal and Dwarf Progeny from Dwarf Dams

1973

Ten Cornish-type commercial broiler breeder sires and ten dwarf males were used to inseminate 100 randomly selected dwarf broiler-type females. Each sire was mated to four to six dams. Individual weight of the egg from which the chick hatched and its eightweek body weight were recorded for 190 male and 191 female normal-bodied crossbreds and 212 male and 232 female dwarf progeny.Among the non-dwarf crossbred progeny from normal sires and dwarf dams, the regression of eight-week body weight on egg weight from which each chick hatched was 11.1 ± 3.1 gms. for males and 8.6 ± 2.1 gms. for females. The regression of broiler weight on mean egg weight for its dwarf dam was 13.8 ± 4.0 gms. for males and 7.6 ± 2.4 gms. for females. Egg weight variation within dam did not significantly affect eight-week body weight of its normal progeny. The crossbred broilers from dwarf dams appeared to be influenced by egg size similar to that observed in the commercial broiler progeny produced from normal dams.The effect of egg weight on eight-week body weight of dwarf males was curvilinear, reaching its maximum at an egg weight of 63 gms., which was close to the mean egg weight (62.3 gms.) for dwarf dams from which male dwarf chicks were hatched. This quadratic effect was significant on both an individual egg weight and within dam family basis. Whereas, for the dwarf female progeny, linear regression coefficients computed on the basis of individual egg weight (4.6 ± 1.8) and within dam family basis (7.1 ±2.6) were significant. A non-significant relationship was observed between eight-week body weight of dwarf progeny and mean egg weight of dwarf dams. Sex linked genetic effects appeared to be important in determining eight-week body weight of dwarf males; whereas, maternal effects and/or non-additive genetic variance were important for determining eight-week body weight of crossbred normal male progeny from dwarf dams.

“…Egg size, chick size, and subsequent broiler growth are positively correlated (Goodwin, 1961;Deaton et al, 1979;Proudfoot and Hulan, 1981). Kosin et al (1952), Bray and Iton (1962), and Gardiner (1973) have concluded that as broilers age, the early influence of egg and chick weight on body weight rapidly decreases. Hays and Spear (1952) studied the age of parents and its effect on chick mortality.…”

The Effect of Maternal Age on Broiler Performance on Litter and a Raised Perforated Floor

1985

View full text Add to dashboard Cite

The effect of maternal age and floor type on the performance of broiler chicks was studied. Hatching eggs were collected and hatched from the same Cobb commercial strain of broiler breeder hens at 27, 42, and 52 weeks of age. Chicks from each group were reared separately or intermingled on commercial diets. Maternal age had a significant effect (P less than .05) on live body weights of broilers reared either separately or intermingled. Weight differences found at day-old between chicks from 42- and 52-week-old dams were overcome by the age of 44 days. Chicks from the 27-week-old dams were not as heavy and consumed less feed than those from other parentage groups. Broilers on the perforated floors were heavier than their floor counterparts. Overall performance, except for body weight, was not affected by floor type or rearing condition.
