“…The yolk sac is infected by bacteria, especially E. coli at the time of egg collection for incubation and at hatching or right after hatching before the navel heals [29]. A higher antibody titer in hens indicates higher quantities of antibodies transferred to chicks and concurrently providing a long-lasting passive immunity [30]. This may be the reason for the high WBC count and monocyte percentage in the FBDOC observed in the current study.…”

Background and Aim: The quality of day-old chicks is a cornerstone to successful poultry production. Chicks with a poor quality start slowly in the field and may have high feed intake, poor growth rate, and poor feed conversion ratio. The current study aimed to assess chick quality challenges encountered from day-old chicks hatched in most commercial hatcheries in Ghana. Materials and Methods: A total of 300 day-old chicks each were obtained from commercial hatcheries in Ghana and Europe. The chicks were labeled as locally hatched broiler day-old chicks (LBDOC) and foreign hatched broiler day-old chicks (FBDOC), respectively. Chicks were reared and monitored from day old to 21 days post-hatch. Sample of chicks (n=25) from each hatchery was euthanized weekly at 1, 7, 14, and 21 days and blood samples collected for analysis. The parameters measured included physical, hematological, immunological, histological, and bacteriological characteristics. All data were analyzed by SAS Proc GLM at p<0.05. Results: The live weight of chicks was higher in FBDOC compared to LBDOC on the 1st day. The chick length and shank length of FBDOC were longer than the LBDOC. The 7-day chick mortality was 6% in LBDOC as compared to 1.5% in FBDOC. The LBDOC also had a higher wet and dry residual yolk sac percentages as well as higher residual yolk sac fluid volume than the FBDOC. The rate of yolk sac disappearance of the FBDOC was higher than the LBDOC. More than half of the LBDOC had developed navel strings and leaky navel compared to FBDOC. The LBDOC recorded Escherichia coli, Proteus, Streptococcus spp., and Gram-negative bacteria in the residual yolk sac isolated through the 21 days while FBDOC recorded E. coli, Proteus, and Gram-negative bacteria. The intestinal villi count, lengths, width, and surface area were all not significantly different. The blood monocyte levels appeared higher in FBDOC than LBDOC, which give evidence of higher immunity in FBDOC than LBDOC. Conclusion: The results indicate a challenging situation in maintaining the quality of locally hatched broiler day-old-chicks compared to foreign hatched broiler-day-old-chicks. The study demonstrates that chick quality impact goes beyond the physical characteristics of chick weight and chick length, and the higher performance of FBDOC may be influenced by compliance with international hatchery standards and vaccination protocols.

“…Quality of day old chick is a very essential factor for profitability of poultry producers. In hatcheries, the chick quality is determined by quantitative and qualitative scoring, considering various numerical or observation quality criteria (Sozcu and Ipek ,2015). For poultry producers it is difficult to get day-old-chicks of good quality from local hatcheries.…”

There is a decrease in poultry production in Iraq. The study was conducted in Babylon Province, Iraq; to identify constraints facing broiler producers. One hundred poultry producers were randomly selected. A list of 4 of constraints facing poultry producers: production, financial, marketing and institutional, covering 24 constraints was prepared. More than half of poultry producers indicated there was a high level of constraint facing them. Production, financial, and marketing constraints had high effect on producers. High cost of feed, competition from imported birds, price fluctuation, high cost of energy, inappropriate environmental conditions, continuous outage of electricity, high cost of drug and vaccines, high mortality rate, competition of birds from other province, lack of quality day old chicks from local hatcheries, lake of capital, poor extension service, production halls not utilized at full operating capacity, lack of quality feeds, and disease attack were the most severe constraints. Negative significant relationships exist between years of experience in poultry production, number of chicken sets/ year, training attendance and overall constraint score. There were differences between constraints severity depending on years of experience, number of chicken sets/ year, and training attendance. Challenges facing poultry producers can be addressed through active extension services. 91 MethodologyThe study was carried out in Babylon province, center-south of Iraq, which is located between 32° and 33.25° North latitude and 44°to 45° East longitude. There are 273 productive poultry projects in the province as at 2016, with the province coming second in term of number of broiler projects and third in terms of amount of meat produced (Central Statistical Organization Iraq, 2017). The population for this study consisted of 273 owners of poultry farms, 13 were chosen for testing reliability of the questionnaire, one hundred poultry farms were selected randomly from the remaining 260 to provide data from 1-15 July 2018.The instrument used was a 2-part questionnaire. The first part included the socio-economic characteristics: years of experience in poultry production, number of productive halls, number of chickens set/ year, number of chicken/set and training attendance. The second part listed 24 constraints faced by poultry producers grouped into the categories: production constraints (10), financial (7), marketing (4), and institutional (3).Content validity of the questionnaire was established by a panel of experts in the field of agricultural extension and poultry production. A pilot study was conducted to establish reliability of the instrument, a Cronbach's alpha (a reliability coefficient) of 0.93 was established, indicating the instrument used was reliable and valid. Constraints were measured on a 5-point continuum scale as very high constraint (VH) (4), high (H) (3), moderate (M) (2), less (L) (1) and not a constraint (NT) (0). In relation to their level of vulnerability, in all-over constraints, each re...

“…Even slight imbalances in chick quality can substantially impact the performance and profitability of the broiler farms. Various methods and parameters are considered in the DOC quality assessment, including the visual evaluation of physical traits, and measuring the level and uniformity of maternal antibodies against specific infectious agents that are relevant in the local contexts [ 1 , 2 ].…”

The present study aimed to investigate the quality of newly hatched broiler chicks delivered to Hong Kong (imported or local), and to develop tailored recommendations to improve their management. During 2019–2021, 70 batches (34 imported from mainland China and 36 local) of one/three day old chicks on 11 broiler farms were studied. From each batch, 23 or 24 chicks (1647 in total) were assessed for abnormalities in appearance, navel, crop filling, dehydration, body weight, and length uniformity. Chicks were sacrificed, and yolk sac residues in three day old chicks were measured. Maternally derived antibody levels against Newcastle disease virus (NDV), infectious bursal disease virus (IBDV), and avian reovirus (ARV) were measured in all chicks using an enzyme-linked immunosorbent assay (ELISA). The proportion of abnormal navel in most batches is high (median: 59%), ranging between 0 and 100%. The average length of chicks within batches ranges between 16.3 and 20.7 cm, and their average weights are 31–38.5 g upon delivery to the farms. On average, imported batches have a higher body weight and length than their local counterparts. The average yolk-free weight varies between 45 and 55 g, which is significantly lower in local batches (33–43 g). The mean antibody titers against NDV and ARV are higher in imported batches than in the local ones. In contrast, the mean antibody titer against IBDV is significantly lower in the imported batches. Concerning the overall lower quality of local chicks compared to the imported batches, establishing a well-managed broiler breeder farm and a hatchery in Hong Kong is highly recommended to enhance the health and productivity of the local broiler chicken industry.
