“…Grading of chicks was performed on the conveyor and automatic grading table while chicks counting and packing was performed through chick counter (KUHL-USA). Only stranded (shining eyes, soft legs and nose, healed naval and healthy chicks) were shifted to chick's box after counting, while underweight, weak, and unhealed naval chicks were removed as an international standard as described by Yousaf et al (2017).…”

The purpose of study was to evaluate the influence of hairline crack eggs on hatchery parameters and later life of chicks. The study was conducted from October to December 2018 at Chakri hatchery Salman Poultry Pvt. Ltd Pakistan to evaluate the outcomes of hairline crack eggs. The shell of the eggs is essential in providing the shape of an egg and ensuring the safe packaging. The defects like breakage of this packaging increase the risk of microbial contamination. In this experiment, the crack eggs like hairline crack eggs were detected by Sanovo STAALKAT Alpha 125 Machine number JB 11786. The eggs were collected from eighteen different breeder farms. Each group contained (n=50,000) eggs. The hairline crack eggs were compared with normal eggs for hatchability, candling, putrification/blasting and dead in shell. Significant difference was found for hatchability, candling, blasting/putrification and dead in the shell for normal and hairline crack eggs. The highest hatchability (49.07±0.51) and lowest candling (9.98±0.064) for hairline crack eggs were found for AP27 flock due to young age and good quality eggshell. The lowest hatchability was found for SP117 flock which was the oldest flock having thin egg shells. The blasting/putrification and dead in the shell were significantly higher for hairline crack eggs as compared to normal eggs of same flocks. The lowest blasting was found for AP27 flock. On a simple hatch debris analysis, the highest mortality, infertile, contaminated eggs were for first and third weeks. The higher mortality were found for hairline crack eggs as compared to the normal eggs for SSF5 flock. The water loss, chick yield and culling chicks percentage were also significantly better for normal eggs compared to hairline crack eggs. The hairline crack eggs of young flocks were better than old flocks due to a better quality of eggs shell. The chicks from normal eggs were also significantly better than chicks from hairline crack eggs in terms of mortality, feed intake, weight gain and FCR. The hairline crack eggs are the source of contamination. Present study recommended that hairline crack eggs do not use for incubation.

A cross sectional study was conducted from July 2017 to October 2017 in potohar region (District Rawalpindi) Punjab-Pakistan with the objectives to determine the prevalence of poultry coccidiosis. A total of n=420 faecal samples were examined using flotation technique to detect coccidian oocysts. The study revealed 23.80% were positive for coccidian oocysts. The prevalence of coccidiosis was accounted 16.27%, 22.22%, 23.61%, 25.71%, and 32.83% in Chakri, Dandi, Dahari, Rawat and Nela Dolha respectively. Significantly (P<0.05) highest prevalence of coccidiosis was recorded in Ross-308 (24.61%), Cobb-500 (24.37%) and lowest in Hubbard Classic (22.30%). Among age group higher prevalence rates (31.67%) was observed in young (<4weeks) than adult chicken. Young chicken had (P>0.05) higher risk of acquiring coccidiosis than adult. Higher prevalence of 28.57% was recorded in intensive poultry birds as compared to chicken kept under extensive management system (21.42%). Even though relatively higher prevalence of coccidiosis was recorded in male (28.49%) than female chicken (20.79%). In conclusion, the present study showed that coccidiosis is an important disease of poultry and this warrants appropriate control strategies need to be designed in order to reduce the impact of poultry coccidiosis in the study area.

“…3 Chick quality has great importance for broiler breeder producer who is paid based on number of saleable chicks and also broiler producer who wants high-quality, fast growing and uniform broilers. 4 The chick quality is affected by some factors, such as breeder age, egg size, hatching time and incubation conditions. 5 The operation and management of hatchery is vital towards the development of quality day old chicks.…”

“…Various breeding practices and handling of eggs from egg laying to hatching of egg have an influence on the hatchability, particularly storage condition temperature, along with the age of breeding flock have been the most common variable used to manipulate the fertility, hatchability, livability and consequently effect on the quality of day old chick. 6 The studies have declared that hatching egg quality and incubation conditions significantly influence the post-hatch performance of broilers [4][5][6][7] The incubation period of chicken (Gallus gallus) embryo is approximately (506 hours) 21.08 days including drying down, and the gap among first to last chick hatch time is approximately 12 to 24 hours. 8,9 This time interval between first and last chick hatch is called "Hatch Window".…”

This study was carried out to find out the effects of breeder age on incubation results, intestinal development during hatch window, chick quality and first week broiler performance. A total of n=259280 eggs were obtained from commercial Ross-308 broiler breeder flocks at 32 and 52 weeks old, which were equally divided on the basis of breeder age in two groups A (Young 32 weeks), B (old 52 weeks age). These 32 and 52 weeks old flocks, 30% and 7.0% were hatched 24 h before pull time and 50% and 60% were hatched 12 h before pull time, respectively. Hatchability of fertile eggs and hatchability of total eggs were found higher in 32 weeks old flock than the other. The chick hatch weight was determined as 39.5 g and 42.1 g in 32 and 52 weeks old flocks, respectively. Chick weight/initial egg weight rate was found to be higher as 67.3% in the 32 weeks old flocks. On hatching day, chick length was also higher in 52 weeks old flock. Relative yolk-free chick weight was higher in 32 weeks old (86.0%) flock than the other (83.0%). Intestine weight rate was higher as 5.24% in chicks from 32 weeks old than the other (4.96%). At 1 week of age, the body weights and weight gains were 167.5 g and 162.7 g, and 128 g and 120.6 g in 32 and 52 weeks old flocks, respectively. Higher mortality ratio as 1.9% was observed in 52 weeks old flock. In conclusion, intestinal development during hatch window, incubation parameters, chick quality and first week broiler performance is affected by breeder age.
