Growth and Carcass Physical Components of Thin Tail Rams Fed on Different Levels of Rice Bran
Get PDFThis experiment was aimed to investigate the effect of rice bran supplementation on live weight gain (LWG), the proportion of carcass meat, bone and fat of Thin Tail Rams. Twelve thin tail rams, aged about 12 months, weighed 20.95 ± 1.52 kg (CV = 7.26%) were allocated into a Randomized Block Design with 2 blocks and 3 treatments. The treatments applied were levels of rice bran supplementation, i.e. Napier grass ad libitum without rice bran (T1), Napier grass ad libitum and 200 g rice bran (T2) and Napier grass ad libitum and 400 g rice bran (T3). The results showed that rice bran supplementation highly significantly (P0.05) influence the percentage of carcass meat and bone percentage. It was concluded that rice bran supplementation increased slaughter weight, carcass weight and carcass percentage, carcass meat and bone weight, and carcass fat percentage, but did not influence the percentage of carcass meat and carcass bone.

Addition of Medicinal Weeds in The Ration on Broiler Chicken Performance
Get PDFAn experiment was conducted to compare the effect of feeding medicinal weeds namely bandotan, patikan kebo and sidaguri on broiler chicken’s performance. The experiment used 100 broiler chicken 3 days of age and were kept for 5 weeks in battery cages. Each cage was 100 x 80 x 60 cm of size and consist 5 chickens. Design of this experiment was assigned to Completely Randomized Design (CRD) with 4 treatments and 5 replications. The treatments were R0 (Basal ration without medicinal weed), R1 (95% basal ration + 5% bandotan (Ageratum conyzoides L)), R2 (95% basal ration + 5% patikan kebo (Euphorbia hirta L)) dan R3 (95% basal ration + 5% sidaguri (Sida cordifolia)). Ration and drinking water were ad libitum. Measured parameters were feed consumption, average daily gain and feed conversion ratio. Data were analyzed by analysis of variance (ANOVA) and the significant effects by Duncan’s multilple range test (DMRT). Results of this study showed that feeding 5% of medicinal weeds either bandotan, patikan kebo or sidaguri had similarly effect (P>0,05) on feed consumption, average daily weight gain and feed conversion ratio of broiler chicken. However, bandotan and sidaguri resulted average daily weight gain lower than patikan kebo. It is concluded that medicinal weeds bandotan, patikan kebo and sidagu could be fed to the chicken up to 5% without significant effect on broiler performance. Patikan kebo resulted better broiler performance than that of bandotan and sidaguri. (Animal Production 11(2): 103-108 (2009) Key Words: Ageratum conyzoides, Euphorbia hirta L, sida cordifolia, weed
Polymorphism of the Growth Hormone Gene and its Association with Growth Traits in Ongole Grade Crossed with Simmental Cattle
No full textThe present study was conducted to detect polymorphism of growth hormone (GH) gene in Ongole grade crossed with Simmental bull (SIMPO) and its association with growth traits. Blood samples of 62 cattle were taken from population of SIMPO cattle were located in the sub-province region of Bantul, Special Region of Yogyakarta. A 211 bp fragment of GH gene spanning from the forth intron region (49 bp) to fifth of exon (162 bp) was amplified and digested with AluI restriction enzyme to identified polymorphism at this locus. The resulted indicated that two genotypes LL and LV were found at the GH gene in SIMPO population cattle. The frequencies of L and V alleles were 0.82 and 0.18, respectively. In SIMPO calves, the average birth weight, 2 months body weight and daily body weight gains of LV genotypes were tend to higher than that of LL genotypes.

The Neutral Detergent Fiber Digestibility of Some Tropical Grasses at Different Stage of Maturity
Get PDFThe digestibility of neutral detergent fiber (IVNDFD) was determined by Telly and Terry methods in vitro on 5 tropical grasses species, Sorghum, Themeda, Iseilema, Brachyacne and Dicanthium. Stem and leaf samples were harvested at different maturity stages, started from early flowering stage to the stage when the grasses were dried. In general, IVNDFD ranged from 22% to 41%. Stages of maturity affected IVNDFD in 4 species; IVNDFD was higher in the stems than in the leaves for 2 species out of 5 species of grasses; the rest was similar. There was no correlation between NDF and IVNDFD, showing that NDF degradability in the rumen was vary. Digestibility potential of NDF (PDNDF) varied from 21% to 44% and has negative correlation with IVNDFD (r=0.75). Growth affected PDNDF in 2 species; and 3 out 5 species observed showed PDNDF in the leaves was higher than that in the stems. Negative correlation was exist between dry matter digestibility (IVDMD), water soluble extract (WSE) and protein with PDNDF. Grasses with stated PDNDF values have relatively high NDF retention in the rumen, which will cause low NDF or dry matter consumption.

The Effect of Soybean Hulls Substitution Levels to Corn in The Ration on Energy and Protein Digestibility and on Sheep Performance
No full textAn experiment was conducted to investigate the effect of soybean hulls levels substitution in to corn as ration in twenty seven rams. The animal had a mean of live weight of 12.86 ± 1.94 kg. Levels of substitution were 0, 50, and 100% or 0, 25, and 50% ration dry matter basis and rations were iso-nitrogeneous. Analysis of variance were conducted for completely randomized design and polynomial orthogonal test were applied for the statistical analysis. Inclusion of soybean hulls in 50% ration dry matter had no effect on daily gain (99.71 ± 22.97 g), and digestible crude protein (62.43 ± 6.56 %). However, dry matter consumption tended to increase linearly and as soybean hulls level increase in the ration (P<0.01). The digestible energy significantly decrease linearly (P<0.01), whereas intake of the energy had same was 1.27 ± 0.33, 1.44 ± 0.17, and 1.23 ± 0.19 Mcal/day for ration containing 0, 25, 50% of soybean hulls, respectively. It was concluded that the soybean hulls may be substituted for corn. (Animal Production 2(2): 98-103 (2000) Key words : soybean hulls, corn, digestibility, daily gain
Effects of Decontamination Using Organic Acids on Total Microbial Number and Qualities of Poultry Carcasses
No full textTujuan Penelitian adalah mempelajari pengaruh dekontaminasi menggunakan asam terhadap jumlah mikroorganisme dan kualitas pada karkas ayam selama penyimpanan sehingga dapat digunakan untuk menentukan metode dekontaminasi karkas yang dapat diterapkan pada rumah potong ayam skala kecil atau rumah tangga. Penelitian dilaksanakan dengan Rancangan Acak Lengkap dengan 5 perlakuan dekontaminasi yang terdiri atas perendaman karkas selama 5 menit dalam air dingin (A), asam laktat (B), asam sitrat (C), dan asam asetat (D), masing – masing dengan konsentrasi 2%. Karkas kemudian disimpan pada kondisi kamar dengan cara digantung. Masing – masing perlakuan diulang 4 kali. Peubah yang diamati terdiri atas (1) peubah kualitas mikrobiologis karkas, yaitu jumlah total bakteri, (2) peubah kualitas fisik daging (pH dan WHC), dan (3) peubah kualits organoleptis (warna, bau dan lendir). Peubah diukur sebelum perlakuan, pada 0 jam setelah perlakuan, kemudian setelah 2,4,6 dan 8 jam setelah perlakuan. Hasil menunjukkan dekontaminasi menyebabkan penurunan jumlah mikroba secara drastis dari 104 menjadi 101 cfu/g. Namun demikian, tidak terdapat perbedaan pengaruh yang signifikan antar masing – masing metode terhadap penurunan jumlah mikroba. Jumlah mikroba kembali meningkat seiring dengan lamanya masa simpan. Penggunaan asam organik meyebabkan penurunan jumlah mikroba. Jumlah mikroba kembali meningkat seiring dengan lamanya masa simpan. Penggunaan asam organik menyebabkan penurunan pH karkas. Sampai penyimpanan 8 jam pada kondisi ruang, kualitas fisik karkas (pH dan WHC) tidak ada perubahan yang berarti dan munculnya lendir pada permukaan karkas belum terdeteksi oleh panelis. Dapat disimpulkan bahwa untukmemperpanjang masa simpan dan meningkatkan kemanan, maka perlu dilakukan dekontaminasi pada karkas ayam, yaitu dengan perendaman pada larutan asam (laktat, sitrat atau asetat) 2% selama 5 menit. Karkas yang telah didekontaminasi dapat disimpan sampai dengan 8 jam pada kondisi ruang.
