Abstract

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.

Abstract

Tujuan dari penelitian ini adalah untuk mengevaluasi ekstrak jahe, kunyit dan daun jati dalam bentuk nano cair yang ditambahkan dengan probiotik pada pakan terhadap persentase karkas dan kualitas fisik daging ayam pedaging. Variabel yang diamati dalam penelitian ini adalah persentase karkas dan kualitas fisik daging yang meliputi kadar air, WHC (Water Holding Capacity), susut masak, keempukan, dan warna (L*, a*, b*). Penelitian dilakukan selama 35 hari secara in vivo. Penelitian ini menggunakan 200 ekor DOC ayam pedaging strain Lohmann dengan berat rata-rata 43,42 g ± 2,82 dan koefisien keragaman 6,48 %. Pakan dan minuman diberikan secara ad libitum. Metode yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 5 level perlakuan feed additive (0 %, 0,2 %, 0,4 %, 0,6 % dan 0,8 %) dimana setiap perlakuan terdiri dari 5 ulangan. Data yang diperoleh dianalisis dengan menggunakan analisis varians (ANOVA) dan apabila terdapat perbedaan nyata dilanjutkan dengan Uji Jarak Berganda Duncan (DMRT). Hasil penelitian bahwa pemberian feed additive ekstrak jahe, kunyit daun jati dan probiotik bentuk cair menunjukkan persentase karkas pada P4 sebesar 80,52 %, kadar air pada P4 68,17 %, WHC pada P3 45,33 %, susut masak pada P3 26,63 % keempukan pada P0 5,95 kg/cm2, warna L pada P2 51,93, a* pada P4 1,01 dan b* pada P4 6,90. Penambahan feed additive berupa ekstraksi jahe, kunyit, daun jati berbentuk nano cair dan probiotik level 0,4 – 0,8 % optimal dalam meningkatkan persentase karkas dan kualitas fisik daging (WHC, cooking loss, warna dan keempukan) pada ayam pedaging.

Abstract

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 ± 0.55 °C and 55.4 ± 4.84%, respectively. At the end of each storage duration, hatching eggs were incubated at temperature and relative humidity of 37.8 ± 0.08 °C and 58.94 ± 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.
