This study evaluated the effects of pre-hatch thermal programming on internal organ development of crossbred chickens in the first week post-hatch. A total of 200 fertile eggs from a crossbreed of male local chickens and commercial laying hens were used in this study. The average egg weight was 62.76 ± 4.40 g with a coefficient of variation was 7.01%. The eggs were randomly distributed into four treatment groups, each with five replicates (10 eggs per replicate). The treatments were T0: standard incubation maintained at 37.50°C throughout the entire incubation period (control); T1: standard incubation with a 6-hour daily increase to 38.50°C from days 10-18, T2: standard incubation with a 6-hour daily increase to 39.50°C from days 10-18, and T3: standard incubation with a 6-hour daily increase to 40.50°C from days 10-18. After hatch, the chicks were reared for a week and evaluated for internal organ development. The results showed that there were no significant differences among treatments (P>0.05) for all measured variables, including the absolute weights (g) and relative percentages (%) of the internal organ. The absolute weight of the heart, liver, proventriculus, gizzard, and intestine were ranged from 0.69 to 0.84, 2.68 to 2.93, 0.74 to 0.87, 6.48 to 7.05, and 7.94 to 8.42 g, respectively. Whereas, the relative weight of the heart, liver, proventriculus, gizzard, and intestine were ranged from 0.89 to 1.12, 3.46 to 3.79, 0.95 to 1.13, 8.29 to 9.11, 10.24 to 10.82%, respectively. It could be concluded that pre-hatch thermal programming can be considered a safe strategy without compromising internal organ development of crossbred chickens in the early post-hatch period.

This study evaluated the addition of turmeric flour (Curcuma domestica) and acidifier in feed on the production Performance of broilers during the starter phase. The materials used in this study were 240 unsexed DOC with an average weight of 40.55±1.69 g/bird. The research method was an experimental trial using a completely randomized design (CRD). There were six treatments and four replications, divided into T0 (commercial feed/basal feed + 0% acidifier + 0% turmeric powder), T1 (basal feed + 0% acidifier + 2.0% turmeric powder), T2 (basal feed + 0.5% acidifier + 1.5% turmeric powder), T3 (basal feed + 1.0% acidifier + 1.0% turmeric powder), T4 (basal feed + 1.5% acidifier + 0.5% turmeric powder), and T5 (basal feed + 2.0% acidifier + 0% turmeric powder). The results showed that the addition of turmeric flour and acidifier in broiler feed during both the starter and finisher phases had a significant effect (p<0.05) on mortality and no significant impact (p>0.05) on feed consumption, weight gain, starter body weight, and FCR. Adding turmeric flour and an acidifier could not increase feed consumption, weight gain, or starter body weight and reduce FCR. However, the addition of turmeric flour and acidifier was able to reduce mortality rates. Further testing related to dosage is needed to achieve the desired results.

This study evaluated the effect of hatching egg storage at room temperature on hatching performance and day old chick quality of Arab chickens. Two hundreds hatching eggs were obtained at the same day from 55-weeks-old Arab chicken flocks. Hatching eggs were then randomly distributed into four treatments, including 1 day storage (1DS), 4 days storage (4DS), 7 days storage (7DS), and 10 days storage (10DS). Each of those treatment using five replicates and each of replicate consisted of 10 hatching eggs. Temperature and relative humidity in the storage room were 27.9 Â± 0.55 Â°C and 55.4 Â± 4.84%, respectively. At the end of each storage duration, hatching eggs were incubated at temperature and relative humidity of 37.8 Â± 0.08 Â°C and 58.94 Â± 5.66%, respectively, for 516 hours. Result showed that egg storage duration for up to 10 days did not affect (P > 0.05) fertility. However, 4DS treatment had a higher (P < 0.05) hatchability of set eggs and hatchability of fertile eggs. Embryonic mortality was also lower (P < 0.05) in 4DS than the other treatments. Egg storage duration had no effect (P > 0.05) on chick length, hatch yield, and Pasgar score. Whereas, chick weight in 1DS and D4S was higher (P < 0.05) than 7DS and 10DS. Furthermore, saleable chicks in 4DS also higher (P < 0.05) than the other treatments. It could be concluded that hatching egg storage at room temperature for 4 days provides optimum hatching performance and day old chick quality of Arab chickens.

ABSTRACT. The purpose of this research was to investigate the use of candlenut powder (Aleurites mollucana (L.) Willd.) as feed additive on blood profile and meat cholesterol content of broilers. Materials used in this research were 200 day-old broiler chicks. Research method was in vivo on Completely Randomized Design with 5 treatments (P0 = basal diets only, P1 = basal diets + 0.25% candlenut powder, P2 = basal diets + 0.5% candlenut powder, P3 = basal diets + 0.75% candlenut powder, P4 = basal diets + 1% candlenut powder), each treatment was replicated 5 times. Variables measured were blood profile (erythrocyte, hemoglobin, mean corpuscular volume, and mean corpuscular hemoglobin) and meat cholesterol content. Data were analyzed by using Analysis of Variance. Data with significant different effects were further analyzed by using Duncans Multiple Range Test. The results showed that candlenut powder usage as feed additive had a highly significant effect on (P0.01) erythrocyte and hemoglobin levels. Candlenut powder also significantly affect (P0.05) mean corpuscular hemoglobin (MCH), but did not significantly affect (P0.05) mean corpuscular volume (MCV) levels. Broilers fed candlenut powder had lower (P0.01) meat cholesterol content compared to those fed basal diets only. It might be concluded that the use of candlenut powder as feed additive at the level of 1% is safely recommended to give better blood profile and reduce meat cholesterol content of broilers.Pengaruh penambahan tepung biji kemiri terhadap profil darah ayam pedaging dan kandungan kolesterol dagingABSTRAK. Tujuan penelitian ini untuk mengevaluasi pemanfaatan tepung biji kemiri (Aleurites mollucana (L.) Willd.) sebagai aditif pakan terhadap profil darah dan kandungan kolesterol daging ayam pedaging. Materi yang digunakan adalah 200 ekor day old chicks (DOC) ayam pedaging. Metode penelitian menggunakan percobaan in vivo pada Rancangan Acak Lengkap (RAL) dengan 5 perlakuan (P0 = pakan basal, P1 = pakan basal + 0.25% tepung biji kemiri, P2 = pakan basal + 0.5% tepung biji kemiri, P3 = pakan basal + 0.75% tepung biji kemiri, P4 = pakan basal + 1% tepung biji kemiri), setiap perlakuan diulang sebanyak 5 kali. Data dianalisis menggunakan analisis variansi (ANOVA) perbedaan yang signifikan dilanjutkan dengan Uji Jarak Berganda Duncans. Hasil penelitian menunjukkan bahwa pemanfaatan tepung biji kemiri sebagai aditif pakan memberikan perbedaan yang sangat nyata (P0,01) terhadap jumlah eritrosit dan hemoglobin. Tepung biji kemiri juga memberikan pengaruh yang nyata (P0,05) terhadap mean corpuscular hemoglobin (MCH), tetapi tidak memberikan pengaruh yang nyata terhadap mean corpuscular volume (MCV) darah ayam. Ayam pedaging yang diberi pakan dengan penambahan tepung biji kemiri memiliki kandungan kolesterol daging yang lebih rendah (P0,01) dibandingkan dengan yang hanya diberi pakan basal. Kesimpulan dari penelitian ini adalah bahwa penambahan tepung biji kemiri sebanyak 1% dapat memberikan profil darah yang lebih baik dan efektif untuk menurunkan kandungan kolesterol daging ayam pedaging.ABSTRACT.

This research was aimed to determine the effect of ant nest treatment (Myrmecodia pendans) on quail production and performance. Research sample was 250 quails. Ant nest was administered in 5 treatments and 5 replications: P0 (0%) as control treatment, P1 (0.2%), P2 (0.4%), P3 (0.6%), and P4 (0.8 %) treatments. Data were collected from quails at 28 days to 70 days old. Variables measured were the performance and quail's egg production. This study was designed using completely randomized design. Real significant difference was examined utilizing Duncan's Multiple Range Test (DMRT). Analysis of variance result showed that ant nest provides significant influence to feed intake and Hen Day Production (P <0.05). The highest average of feed consumption is treatment P4 (0.8%), whereas treatment P0 (0%) was the lowest average for feed consumption. Feed conversion rate in treatment P4 (0.8%) was more efficient compared to other treatments. Ant nests administering did not result significantly different (P> 0.05) to feed conversion and egg mass. The results of the study concluded that higher ant nest administration is capable of increasing quails feed intake and Hen Day Production. Keywords: basal feed, flavonoids, productivity.
