Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh letak cage dalam kandang tertutup terhadap kualitas telur ayam petelur Hy-Line Brown. Materi yang digunakan adalah 96 ekor ayam petelur Hy-Line Brown umur 57 minggu. Pakan yang digunakan adalah pakan lengkap untuk ayam petelur fase layer produksi PT. Charoen Pokphand Indonesia dengan kode 324 KJ. Metode penelitian adalah percobaan menggunakan Rancangan Acak Lengkap. Perlakuan penelitian adalah tiga letak cage yang berbeda, yaitu dekat inlet (P1), tengah (P2), dan dekat outlet (P3).  Variabel penelitian meliputi luas permukaan area telur, kedalaman kantong udara, dan berat jenis. Data dianalisis menggunakan analisis sidik ragam dan jika terdapat perbedaan antar perlakuan dilakukan uji Duncan. Hasil penelitian menunjukkan bahwa tidak terdapat perbedaan yang nyata (P>0,05) pada luas permukaan area telur, kedalaman kantong udara, dan berat jenis telur pada letak cage yang berbeda dalam kandang tertutup. Kesimpulan pada penelitian ini adalah bahwa letak cage dalam kandang tertutup tidak memberikan pengaruh negatif terhadap kualitas telur ayam Hy-Line Brown. Disarankan dilakukan penelitian uji pH darah untuk mengukur tingkat cekaman ayam petelur pada letak cage yang berbeda.

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.

Abstract

The purpose of this current study was to evaluate the influence of nutritional flushing on body morphometrics of female breeding goats. This study used 32 local female goats or does with an average age of 3.281.08 years and an average body weight of 42.478.28 kg. The goats were distributed in a completely randomized design using a 2 x 2 factorial pattern with 8 replications. The first factor was the flushing feed (FF) type, consisting of rice bran and concentrate, whereas the second factor was the level of tannin-protected arginine (TPA: 0 and 300 mg/kg). The body morphometrics observed in this study were initial body length (IBL), final body length (FBL), body length change (BLC), initial chest girth (ICG), final chest girth (FCG), chest girth change (CGC), initial wither height (IWH), final wither height (FWH), and wither height change (WHC). The IBL, FBL, BLC, ICG, FCG, IWH, FWH, and WHC of the local does were not significantly different (P0.05) after receiving the FF type. However, FF significantly affected the CGC of the goats (P0.001). The use of concentrate for the local female local goats resulted in a higher CGC (P0.001) compared to the use of rice bran. On the other hand, TPA did not significantly affect all body morphometrics of the goats (P0.05). Thus, it can be concluded that the use of concentrate leads to higher chest girth change, giving better body growth compared to the use of rice bran. The addition of tannin-protected arginine was also found to have no significant contribution to the body morphometrics of the local female goats. _____________
