“…Kampung chickens have high adaptability to their environment (Horhoruw & Kewilaa, 2024;Sirait et al, 2023). Free-range chickens have several advantages compared to purebred chickens in terms of maintenance, such as resistance to certain diseases and relatively easy maintenance (Schreiter & Freick, 2023). Products from non-purebred chickens, such as eggs and meat, have special features and are difficult to replace with other commodities.…”

“…Products from non-purebred chickens, such as eggs and meat, have special features and are difficult to replace with other commodities. In addition to advantages, free-range chickens also have several disadvantages, such as slow growth, low production, still incubation properties, slow gender maturity, long egg-laying interval due to parenting, and low genetic quality (Schreiter & Freick, 2023) In order to keep pace with production figures, the increase in the number of kampung chicken populations is one indicator of business development (Lisnahan et al, 2023;Zainudin, 2022). The increase in kampung chicken populations is influenced by various factors, one of which is breeding or providing kampung chicks through artificial hatching technology (Haryuni et al, 2020;Saragih et al, 2024).…”

This research aimed to determine the influence of egg shape on the gender and abnormalities of hatched kampung chicks, conducted over one month in Wailela Hamlet, Ambon City. Using an experimental method with a quasi-experimental design, the study observed 120 kampung chicken eggs less than five days old. Data were collected by directly observing hatched eggs and chicks using hatching machines and digital scales. The eggs were cleaned, identified, and numbered before placement in a fumigated hatching machine. Ventilation and screening maintained temperature and humidity stability. The chi-square test (X2) analyzed the effect of egg shape on gender and abnormalities. The study's significance lies in its potential to improve breeding practices by understanding the impact of egg shape on hatching outcomes. However, the results indicated that egg shape did not significantly affect the gender or abnormalities of the hatched chicks. Consequently, egg shape cannot be used as a reliable criterion for selecting eggs to determine the gender or abnormalities of kampung chicks. This insight highlights the need for genetic or molecular techniques for gender determination and suggests further research with larger samples to explore other influencing factors.

Micelle silymarin (MS) is known for its various beneficial properties, including antiswelling, antioxidant, hepatoprotective and antidiabetic effects. The primary goal of this research was to investigate how MS impacts the performance, egg quality, water loss and blood profile of laying hens. 288 Hy‐Line brown laying hens, 28 weeks in age, were utilized for this experiment. The hens were randomly allocated into three dietary treatment groups, with each group comprising eight replicates of 12 hens, each housed in individual pens with access to feed and water. Over a 12‐week feeding trial, the hens were provided with a basal diet supplemented with different levels of MS: 0%, 0.03% and 0.06%. The results indicated that the inclusion of MS in the hens’ diet did not have a significant impact on their performance (p > 0.05). However, Haugh units, egg weight and eggshell strength showed a linear improvement (p < 0.05) throughout the entire trial period with MS supplementation. Furthermore, there was a linear decrease in egg yolk colour and eggshell thickness showed linear improvements (p < 0.05), particularly during Week 8, with MS supplementation. Moreover, layers fed diet supplemented with MS showed a linear increased (p < 0.05) in albumen height and eggshell thickness in Week 12. In addition, egg water loss during Week 12, the third day of incubation, linearly decreased as an effect of the increasing level of the MS in the laying hen's diet (p < 0.05). Regarding blood profile parameters, the study revealed a tendency for alkaline phosphatase to decrease, whereas aspartate aminotransferase and cholesterol levels were linearly decreased (p < 0.05). In summary, increasing the level of MS supplementation in the diet of laying hens appeared to be beneficial in improving egg quality, slight improvement for egg water loss and certain aspects of blood profile parameters, without adversely affecting the hens' growth performance.
