“…This difference was most likely caused by the concomitant increase in age of the parent stock. Effects of strain have been found on hatching time and neonatal live weight of broiler chicks (Ruiz and Lunam, 2002), in accordance with the results of the present experiment. Reis et al (1997) found no differences in live weight at hatch between the sexes, but male chicks tended to hatch on average 3 h later than females.…”

et al. 2010

The feeding activity of 2 strains of broiler chickens was investigated during their first week of life in relation to their hatching time. Fast (Ross 308) and slow-growing (LB) strains were allocated to 1 of 3 (early, middle, or late hatch) single-strain groups of 80 to 100 as-hatched birds in 4 replicates divided into 2 time-separated blocks. Behavioral observations differed between blocks and were carried out at intervals on d 1 to 6, and the percentage of birds feeding (from trough or paper), drinking, or being otherwise active (block 2 only) were registered. A higher mortality caused by flip-over was seen among the late-hatching birds from the slow-growing strain. The percentage of birds engaged in feeding activity was similar for the 2 strains, but LB birds began to eat from the paper later and were observed eating from the trough less than Ross 308 birds, which in turn were less active than LB, especially in the early and middle hatch groups. Early hatch groups were observed feeding from the paper more than the middle and late hatch groups. Drinking behavior mirrored feeding from the trough, indicating that drinking was prandial. Within strain, no effect of hatch time was found on live weight at hatch, but the feeding behavior of early hatched birds led to a small, transient weight advantage on d 3 after hatch. The transition from feeding on paper to feeding only from the trough may have less effect on birds that feed from the trough sooner, such as the fast-growing strain.

“…PEDROSO et al (2005) obtained similar results; these authors mentioned that as the age of breeders advanced, characteristics related to egg fertility and hatchability gradually improved. The effect of age of breeders on hatchability was observed also by RUIZ and LUNAM (2002) who wrote that fertilised eggs stored at higher temperatures showed a reduced hatchability of fertile eggs. SEKER et al (2005) found significant effects between pre-incubation storage and egg weight on hatching results of Japanese quail eggs.…”

Relationship of early laying, number and weight of laid eggs to fertility and hatchability of eggs in initial laying lines of hens

et al. 2010

The relationships between age of hens, number of laid eggs, egg weight on one hand and fertility and hatchability on the other were analysed during two periods of individual pedigree hatching. Altogether 1 369 hens originated from 9 selected initial laying lines of Bar Plymouth Rock (BPR) (3 lines), Rhode Island Red (RIR) (4 lines), Rhode Island White (RIW), and Sussex Light (SUL) breeds. A total number of 23 473 eggs from hens of all 9 aforementioned lines were set after being artificially inseminated. The total average hatchability of set eggs was 73.2 % and the average percentage of unfertilised eggs was 9.3 %. Positive correlations (rp =0.22 to rp =0.72; P<0.01) were found between the total number of eggs laid till the 240th day of age and the number of eggs produced at the beginning of the laying period in the all studied lines. There were negative correlations (rp =−0.03 to rp =−0.16; P<0.01) between the total number of eggs laid till the 240th day of age and the average egg weight (on the 222nd day of age). Zero to positive correlations existed between the total number of eggs laid till the 240th day of age on one hand and the number of hatching eggs, number of hatched chicks/hen and hatchability; the calculated values ranged from rp =−0.02 to rp =0.30 (P<0.01), from rp =−0.08 to rp =0.36 (P<0.01), and from rp =−0.09 to rp =0.30 (P<0.01), respectively. Correlations between the egg weight and number of hatched chicks/hen were negative to zero and their values ranged from rp =−0.19 (P<0.01) to rp =0.02. Correlations between the egg weight and hatchability were always negative (rp =−0.15; P<0.05 to rp =−0.04). Regarding the fact that there is a concurrent selection for an increased egg weight it can be said that this preference of smaller eggs is really counter-productive. A positive relationship between the number of hatching eggs/hen and the hatchability (rp =−0.02 to rp =0.39; P<0.01) was influenced by calculated negative correlations existing between the weight of eggs and the hatchability as well as between the weight of eggs and the number of laid eggs. As far as the hatchability is concerned, it can be concluded that in the aforementioned laying lines those hens are preferred, which produce more eggs of smaller size and that this fact obviously influences also the efficiency of selection for a greater weight of produced eggs.Keywords: laying hens lines, egg weight, egg production, fertility, hatchability Die Brutergebnisse aller Eier lagen bei 73,2 % und der durchschnittliche Anteil unbefruchtete Eier bei 9,2 %.

“…Depending on the supply of hatching eggs, variable market demands for broiler chicks and hatchery capacity, eggs are stored for 3 to 18 days before incubation. But storage longer than 7 days adversely affects embryonic development by slowing embryo metabolism and growth (Christensen et al, 2001;Yalcin and Siegel, 2003;Fasenko, 2007) and chick weight at hatch (Reis et al, 1997;Ruiz and Lunam, 2002). Long-term egg storage also affects the postnatal growth (Tona et al, 2003), however the mechanisms behind have not been clearly understood.…”

The effects of egg storage duration (ESD) and brooding temperature (BT) on BW, intestine development and nutrient transporters of broiler chicks were investigated. A total of 396 chicks obtained from eggs stored at 18°C for 3 days (ESD3-18°C) or at 14°C for 14 days (ESD14-14°C) before incubation were exposed to three BTs. Temperatures were initially set at 32°C, 34°C and 30°C for control (BT-Cont), high (BT-High) and low (BT-Low) BTs, respectively. Brooding temperatures were decreased by 2°C each at days 2, 7, 14 and 21. Body weight was measured at the day of hatch, 2, 7, 14, 21, 28 and 42. Cloacal temperatures of broilers were recorded from 1 to 14 days. Intestinal morphology and gene expression levels of H + -dependent peptide transporter (PepT1) and Na-dependent glucose (SGLT1) were evaluated on the day of hatch and 14. Cloacal temperatures of chicks were affected by BTs from days 1 to 8, being the lowest for BT-Low chicks. BT-High resulted in the heaviest BWs at 7 days, especially for ESD14-14°C chicks. This result was consistent with longer villus and larger villus area of ESD14-14°C chicks at BT-High conditions. From 14 days to slaughter age, BT had no effect on broiler weight. ESD3-18°C chicks were heavier than ESD14-14°C chicks up to 28 days. The PepT1 and SGLT1 expression levels were significantly higher in ESD3-18°C chicks than ESD14-14°C on the day of hatch. There was significant egg storage by BT interaction for PepT1 and SGLT1 transporters at day 14. ESD14-14°C chicks had significantly higher expression of PepT1 and SGLT1 at BT-Low than those at BT-Cont. ESD14-14°C chicks upregulated PepT1 gene expression 1.15 and 1.57-fold at BT-High and BT-Low, respectively, compared with BT-Cont, whereas PepT1 expression was downregulated 0.67 and 0.62-fold in ESD3-18°C chicks at BT-High and BT-Low. These results indicated that pre-incubation egg storage conditions and BTs affected intestine morphology and PepT1 and SGLT1 nutrient transporters expression in broiler chicks.
