“…In addition, mortality at 7 d was numerically lower in the 60 h preplacement holding time group than 6 h preplacement holding time group (0.81 vs. 1.02%). This finding was consistent with those of Casteel et al (1994) , Corless and Sell (1999) , Daşkiran et al (2012) , Özlü et al (2020) and Dişa et al (2022) that sending the chicks earlier (6 h) did not reduce the first week mortality.…”

“…Perhaps more importantly, in many of the experiments, the ‘delayed’ chicks were held in unsuitable conditions (boxed within the heated poultry house), which could be expected to raise early mortality. In a recent study, ( Dişa et al, 2022 ) with relatively large pen sizes (200 chicks/pen), sending the late hatch chicks to the broiler house shortly after hatching (7 h) increased the mortality at 41 d, unlike holding early hatched chicks for a relatively long time (50 h) in the hatcher.…”

“…According to [8] delayed delivery of chicks to the breeder has a negative impact on their live performances. In addition, in the farming process, the number of chicks in the livestock does not match the production of broiler chickens.…”

Deli Serdang Regency is a potential area for the development of broiler industry. The main challenge for the development of the broiler industry is high price fluctuations, both input and output. Distribution channels are closely related to the supply chain processes, both of which are important in a poultry industry. The supply chain, which also discusses distribution, trains companies to be more targeted in marketing their products. The purpose of this study is to analyze the supply chain and its application to poultry products and find out how the distribution channels are in the supply chain. The research method used is descriptive method. The results obtained state that the broiler supply chain includes: first the raw materials are obtained from PT. Charoen Pokphan, then enters to the livestock farming for 28 days – 35 days, and is sold the butcher entrepreneurs through company agents, after that it distributed to the markets, the restaurants and or to the consumers directly who buy from the butcher entrepreneur. In the supply chain used in the process of supplying chicken meat it is considered too complicated because it has to go through various parties. It is better for the livestock farming to cut the supply chain, so that it can be profitable for the livestock farming, and also maintain the quality of the chicken meat.

“…It has been reported that broilers were able to compensate for 36-54 h of feed deprivation when they were able to access feed for a similar period of time at 35 d [20,21,48] or 41 d [49]. In a similar study by Cardeal et al [50], chicks were subjected to 3, 24, 48, and 72 h preplacement holding times after pulling from the hatchery.…”

“…Given that optimal house brooding temperatures are some 6-8 °C warmer than those normally used in chick delivery vehicles, these birds almost certainly overheated, which could be expected to increase early mortality [27]. On the other hand, in much larger scale experiments, Dişa et al [49] examined the interaction effect of hatching time and pull time on broiler live performance. Chicks were held in the hatcher for 7, 17, 26, 31, 41, or 50 h after hatching, and the highest mortality at 41 d was found in chicks that were held in the hatcher for the shortest time (7 h) (p < 0.001).…”

The effects and interactions of incubation time and chick preplacement holding time on mortality at placement, utilization of yolk sac, crop filling rate, early feeding–drinking behavior, and broiler live performance were investigated. Ross 308 broiler hatching eggs from a 39-week-old flock were set in two identical setters in a commercial hatchery, with the setting time 12 h earlier in one machine. At the end of incubation, chicks were removed from the hatchers at the same time. Thus, the incubation times were either 504 h (normal incubation time (NIT) treatment) or 516 h (longer incubation time (LIT) treatment). After the pull time, chicks from each incubation time group were subjected to either 6, 24, 48, 60, or 72 h preplacement holding times. At placement, chicks were given access to feed and water. In total, 19,200 chicks were randomly assigned to a total of 10 subtreatment groups (2 incubation times × 5 preplacement holding times). Therefore, a total of 1920 chicks were used in each subtreatment group for the grow-out period in a commercial broiler house. For the first week of the experiment, 160 randomly selected as-hatched (not sexed) chicks were placed in 12 replicate floor pens (120 total pens). From the second week of age onward, chicks from two pens were combined into six replicate pens, with 320 chicks per replicate (60 total pens). An interaction was found between incubation time and preplacement holding time for residual yolk sac (RYS) weight (g, %) (p < 0.001). RYS weight was greater at pull time and at 6 and 24 h of preplacement holding in the NIT treatment compared to the LIT treatment, while differences were no longer evident at 48–72 h. The lowest percentage of chicks with full crops and eating activity was observed in the shortest preplacement holding time (6 h) group at 3 h after placement. As expected, the initial BW at placement clearly decreased with increasing duration after the pull time (p < 0.05), with the highest and lowest weights found in the 6 and 72 h holding time treatments, respectively. This BW difference was still evident at 35 d after placement and chicks held for the longest period after the pull time (72 h) showed the lowest BW (p < 0.001). However, there was no significant difference between the 6 and 60 h preplacement holding times. Mortality during the first 7 d after placement increased only when the preplacement holding time was extended to 72 h (p = 0.031). Similarly to the 7 d results, chicks held for 72 h exhibited higher 0–35 day mortality compared to those held for 6 or 24 h (p = 0.028). Neither BW nor mortality was affected by incubation time treatment at 35 d after placement (p > 0.05). It can be concluded that there were no significant differences in average BW and mortality, up to and including a 60 h holding time under thermal comfort conditions, but a 72 h preplacement holding time resulted in final BW and mortality being negatively affected. In addition, LIT tended to have a beneficial effect on BW and mortality compared to NIT when the preplacement holding time was shorter (6–24 h) but had a negative effect for extended holding times (48–72 h).
