PENGARUH ZONA DALAM KANDANG TERHADAP PERFORMA AYAM PETELUR YANG DIPELIHARA DI SEMI CLOSED HOUSE

Abstract

Penelitian ini bertujuan untuk mengidentifikasi variasi kondisi iklim mikro di zona masuk (inlet), tengah, dan keluar (outlet) kandang ayam serta mengevaluasi pengaruh variasi tersebut terhadap kinerja produksi ayam petelur, yang mencakup Hen-Day Production (HDP), massa telur, dan Feed Conversion Ratio (FCR). Sebanyak 240 ekor ayam petelur Isa Brown berusia 48 minggu yang dipelihara dalam sistem kandang semi-tertutup digunakan dalam penelitian ini. Tiga perlakuan berdasarkan zona kandang dan empat ulangan diterapkan menggunakan Rancangan Acak Lengkap (RAL). Data dianalisis menggunakan Analysis of Variance (ANOVA), dan jika ditemukan pengaruh yang signifikan, dilakukan uji Least Significant Difference (LSD) pada taraf 5%. Berdasarkan data yang diperoleh, zona kandang tidak memberikan pengaruh yang signifikan terhadap HDP (P>0,05). Nilai rata-rata HDP untuk zona masuk (P1), tengah (P2), dan keluar (P3) masing-masing adalah 93%, 91%, dan 90%. Perbedaan zona kandang berpengaruh terhadap egg mass, dengan rataan berturut-turut sebesar P1= 1.230,25g^b, P2=1.206,25g^ab dan P3=1.185,75 g^a. Perbedaan zona juga berpengaruh pada  FCR, dengan nilai terendah pada P1 sebesar 1,96^a, diikuti P2 sebesar 2,00^ab, dan tertinggi pada P3 sebesar 2,04^b. Dengan demikian, perbedaan zona dalam kandang tidak memengaruhi HDP secara nyata, tetapi berpengaruh terhadap egg mass dan FCR. Perbedaan mikroklimat antarzona diduga belum cukup besar untuk memengaruh performa produksi ayam petelur secara signifikan.

THE EFFECT OF CAGE ZONES ON THE PERFORMANCE OF LAYING HENS REARED IN A SEMI-CLOSED HOUSE

Abstract

               This study aimed to identify variations in microclimate conditions across the inlet, middle, and outlet zones of a poultry house and to evaluate the impact of these variations on the production performance of laying hens, specifically Hen-Day Production (HDP), egg mass, and Feed Conversion Ratio (FCR). A total of 240 Isa Brown laying hens, aged 48 weeks and housed in a semi-closed system, were used in this study. Three treatments based on housing zones and four replicates were implemented using a Completely Randomized Design (CRD). Data were analyzed using Analysis of Variance (ANOVA), and where significant effects were found, the Least Significant Difference (LSD) test was performed at the 5% level. Based on the obtained data, the housing zone did not significantly affect HDP (P>0.05). The mean HDP values for the inlet (P1), middle (P2), and outlet (P3) zones were 93%, 91%, and 90%, respectively.  Housing zones did influence egg mass, with mean values of P1 = 1,230.25g (b), P2 = 1,206.25g (ab), and P3 = 1,185.75g (a). Zone differences also affected FCR, with the lowest value observed in P1 (1.96a), followed by P2 (2.00ab), and the highest in P3 (2.04b). Thus, while housing zones did not significantly affect HDP, they did influence egg mass and FCR. The microclimate variations between zones were likely insufficient to significantly alter the production performance of the laying hens.
