Abstract The poultry feathers have a very high protein content due to it consists of 90% of crude protein, and it is an ideal material to obtain keratin protein. Due to Keratin’s difficulties and time-consuming decomposition, further processing is needed to degrade Keratin into simpler proteins that can be used as an alternative N-source. This study was aimed to evaluate the keratin hydrolysate from poultry feathers prepared by acidic (HCl) and alkaline (NaOH) compound utilization and its potency as the substrate medium for growth keratinolytic bacteria at a laboratory scale. Poultry feathers, including kampung (local breed) chicken feathers, layer chicken feathers, and local goose treat with HCL 12% and NaOH 20%. The results of the hydrolysate of poultry feathers using 12% HCl showed no significant changes. Visually, the feathers of birds that have been treated with 12% HCl show a colour change to brownish-yellow. The results of hydrolysis using NaOH showed better results than HCl for producing feather meals. The highest yield has occurred at local goose feathers at 95.7%, followed by Kampung and Layer chicken feathers at 93.17% and 78,75%. Based on the viability test, three indigenous strains (Bacillus cereus TD5B, B. cereus LS2B and Pseudomonas sp. PK4) grew in a medium with a substrate of kampung chicken feathers, layer chickens, and local goose feathers. It can be concluded that the hydrolysed poultry feathers made by NaOH 20% preparation had a potency as N-source in the bacterial growth medium.

This study aims for a deep understanding of the business strategy of layer chicken farms during the new normal era in Bali. The expected output in this study focused on the establishment of strategic recommendations that apply to layer chicken farms within Bali to raise the production as well as overcome the challenges during the new normal era new normal. 134 respondents were involved, which consists of 80 consumers, 48 livestock farmers, and 6 experts. Results of IFE-EFE analysis showed that the value of an internal factor is 3.72 and external factor is 2.73 which determine that the business of layer chicken farm is in quadrant IV in matrix IE and categorized group of growth and build strategy. Seven business strategies could be recommended to the farmers in Bali during this new normal era, namely; 1) applying digital marketing; 2) implementation of laying chickens information system (abbreviated as SIAP in Bahasa Indonesia); 3) socialization and empowerment in utilizing e-commerce; 4) collaborating with livestock platforms; 5) training and mentoring for the public regarding a business opportunity in an egg-based product; 6) forming industry cluster of laying chicken farms; 7) development of livestock cooperative.

Eggshells are the hard, outer covering of eggs. It is known that eggshells are discarded as waste materials, although they contain a significant amount of calcium. The study was aimed to extract and quantify calcium from the eggshells and fortification on the biscuit and yogurt products. The extraction of calcium was done using calcium chloride with HCL solution at different propositions (1:1, 1:5, 1:10, 1:15, and 1:20). After extraction, the sample was dried at 50 °C temperature for 3 hours to obtain dry calcium chloride. Calcium was fortified at a concentration of 100 ppm, 1000 ppm, and 2000 ppm in both the biscuits and yogurt, respectively. The calcium-fortified samples were analyzed for sensory properties and chemical composition. The ash content of calcium-fortified yogurt (0.47) was slightly higher than normal yogurt (0.44), while the other chemical components remains similar to the control. For the sensory evaluation result, the biscuit with 2000 ppm calcium-fortified biscuit and 1000 ppm calcium-fortified yogurt was found to be highly acceptable among the calcium-fortified samples. The extraction of calcium chloride from eggshells was obtained the highest for eggshells on HCl ratio 1:20 (w/v) where calcium chloride was found 32.92%, 26.95%, and 23.63% for duck, layer chicken, and local chicken eggshells, respectively. The extraction rate of calcium chloride of duck eggshells was higher than the local and layer chicken’s eggshells. Therefore, it may be opined that the fortified products (2000 ppm Ca) contained a considerably higher amount of calcium content than the control sample.

This study aims to analyze the income of the BUMDes “Mandiri”  layer chicken farm and partner farms, as well as the size of the income earned by BUMDes “Mandiri”  and breeder partners from the profit-sharing system carried out together. The research respondents were the BUMDes “Mandiri”  farm manager and two breeder partners. Operating income is calculated by finding the difference between business revenues and total business costs incurred. The share received by BUMDes “Mandiri”  and partner farmers from partner farm income is determined based on the percentage agreed in the partnership agreement, namely 51% for BUMDes “Mandiri”  and 49% for breeder partners. The results showed that the income of the BUMDes “Mandiri”  livestock business in one month was Rp. 3,668,890.00 or Rp. 3,668.89/head, while the partner's husbandry business income was Rp. 6,404,505.00 or Rp. 12,809.00/head. The portion of the partner's husbandry business income that belongs to BUMDes “Mandiri” is Rp. 3,266,295.00/month and that which belongs to breeder partners is Rp. 3,138,210.00/month.

The experiment was conducted to investigate the effects of substitution of soybean meal of laying hens ration by shrimp head meal (SHM) on physical and nutritional quality of eggs and meats. Three hundred Hisex White laying hens were divided into five treatment groups and allocated five experimental diets included different levels of SHM. Soybean meal contents of control ration was substituted by SHM meal at the rate of 25, 50, 75 and 100%, respectively. Samples of SHM, eggs and meats were subjected to proximate analysis. Physical properties of eggs and meats were also analyzed following the standard procedures. Highest CP contents (%) of eggs were recorded to be 11.39±0.27 and 10.83±0.18 at initial and peak production periods, respectively in laying hens group fed ration substituted SBM by SHM at the rate of 25%. Significantly (p<0.001) highest value of redness (a*) of egg yolk was recorded to be 1.39 in laying hens group fed diet where SBM was completely substituted by SHM and lowest to be -3.11 in control group (no substitution) at initial production stage (18th to 20th week). Significantly (p=0.05) highest CP (%) contents of meats was found to be 19.37±0.36 in laying hens fed diets substituted SBM at the rate of 75% by SHM and lowest in complete substituted group. It can be concluded that substitution of soybean meal of laying hens ration at the rate of 25% by SHM is suitable for better egg and meat quality. Bang. J. Anim. Sci. 2021. 50 (1):12-21

Recent decades were characterized by genetic selection of broiler and layer chickens for enhanced growth rate and meat yield or intensified egg production, respectively. It is to be expected that genetic selection for various traits would also influence embryo development. The effects of different strains of chickens on egg weight, stage of blastoderm, variation of the blastoderm development and Pearson correlation between egg weight and stage of blastoderm at oviposition were studied in the current study. Hatching eggs were randomly collected from three layer chicken lines (Layer-1, Layer-2, and Layer-3) raised in Poultry Research Institute, and two broiler grandparent flocks (Female and Male) from Aviagen Anadolu. The age of all chicken lines was 36 week. A total of 30 eggs in each line were used, and egg weight and the blastoderm development of the embryos were determined at oviposition time. At the end of the research, significant difference in egg weights (P0.05). The mean stage of blastoderm development in male grandparent line eggs significantly lower than other four genetic lines (P
