ABSTRACT

The objective of this experiment  was to determine the effects of different percentage of ration between day and night to male chicken medium type performance;  the best level of percentage of ration that given between the day and night in chicken coop. A total of one hundred and forty four day-old male chicks medium type were divided into 3 treatments and 6 replications, each treatment consist of 8 male chickens. The treatments were ration that given 30% during the day and 70% the night; ration that given 50% during the day and 50% the night; ration that given 70% during the day and 30% the night. This research was conducted from August through October 2018 in Integrated Laboratory Department of Animal Husbandry, Faculty of Agriculture, University of Lampung.  Data were subjected to analysis variance. Significant was considered at 5% level of probability. The results showed, percentage ration between day and night signicant influence feed consumption (P <0.05), but not significant effect to body weight and feed conversion ratio. The percentage of ration given 30% during  day and 70%  night is the best treatment influence feed conversion ratio (2,41) with feed consumption 1.738.03 g/bird  and body weight 718,58 g/bird. Keywords : Male chickens, Ration percentage, Chicken coop

This study aims to identify the quantitative and qualitative performance of native chickens in The Mother breeding farm. This study used 50 male native chickens and 50 female native chickens aged 7 months. Variables observed included body hair pattern color, comb shape, comb color, shank color, eye color, beak color, body weight, chest circumference, shank length, shank circumference, body length, pubic bone length to chest, pubic bone distance and length wing span. Data were analyzed using descriptive analysis. The results of this study indicate that the body color of the male is Columbian (100%), while the female is solid black (62%), columbian (22%) and speckled or dotted (16%). The male cockscomb is pea (86%) and single (14%), while the female is pea (70%), walnut (20%) and single (10%). The color of the male comb is red (100%), while the female is red (98%) and black (2%). The shank color of males is yellow (74%), black (14%) and white (12%), females are black (74%), white (16%) and yellow (10%). Male eye color is orange (76%) and yellow (24%), while females are orange (66%), yellow (20%) and brown (14%). The color of the male's beak is yellow (54%), black and yellow (38%) and white (8%), while the female's beak is black and yellow (82%), yellow (10%) and white (8%). The results of the quantitative characteristics of the study showed that the male body weight was 2.22 ± 2.02 kg and the female was 1.71 ± 0.25 kg, the male chest circumference was 33.9 ± 3.68 cm and the female was 30.67 ± 2.08 cm, the length male shank 9.61 ± 0.89 cm and female 27 ± 0.59 cm, male shank circumference 5.52 ± 0.65 cm and female 4.4 ± 0.5 cm, male body length 20.27 ± 1.17 cm and female 20.40 ± 2.27 cm, the length of the pubic bone to the chest of the female is 7.87 ± 1.06 cm, the distance between the pubic bones is 2.8 ± 0.49 cm, the length of the male wing span is 23.28 ±2.18 cm and females 16.61±2.44 cm. The conclusion of this study is that the quantitative and qualitative characteristics of free-range chickens on The Mother farm are diverse and selection can be made.

This study aimed to study the effect of stocking density on live weight, carcasses and giblets of broiler in closed houses; and to determine the best stocking density on live weight, carcass and giblet of broiler in a closed house.  This research was conducted in April-May 2019 for 28 days with 14 days of treatments period (14-28 days) at PT. Charoen Pokphand (Kandang Bandara 2) located in Bangun Sari hamlet, Way Sari Village, Natar District, Lampung Selatan Regency.  This study used a Completely Randomized Design with four treatments, of stocking density of 15 heads/m2 (P1), stocking density of 17 heads/m2 (P2), stocking density of 19 heads/m2 (P3), and stocking density of 21 heads/m2 (P4), with five replications for each treatment. The data obtained were analyzed using analysis of variance at  5% level. The result of the analysis of variance showed that the different stocking density had no significant effect on the live weight, carcasses, and giblet of broiler at 28 days of age in the closed house.   Keywords:  Carcass, Closed house, Giblet, Live weight, Stocking density

Penelitian ini bertujuan untuk mengetahui pengaruh substitusi tepung daun singkong terfermentasi Aspergillus niger terbaik terhadap bobot hidup, bobot karkas, dan lemak abdominal ayam joper umur 8 minggu.  Penelitian ini dilaksanakan pada Januari–Maret 2022 di Laboratorium Nutrisi dan Pakan Ternak, Jurusan Peternakan, Fakultas Pertanian, Universitas Lampung dan Laboratorium Lapang Terpadu, Fakultas Pertanian, Universitas Lampung.  Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 5 perlakuan (0%, 5%, 10%, 15%, dan 20%) tepung daun singkong terfermentasi Aspergillus niger yang diulang 4 kali dengan total 20 unit petak percobaan, masing-masing unit berisi 4 ekor ayam joper tanpa dibedakan jantan ataupun betina, sehingga jumlah ayam joper 80 ekor. Peubah yang diamati meliputi bobot hidup, bobot karkas, dan lemak abdominal. Data yang diperoleh dianalisis menggunakan analisis ragam (ANOVA) pada taraf nyata 5%.  Hasil penelitian menunjukkan bahwa perlakuan substitusi tepung daun singkong terfermentasi Aspergillus niger 0%, 5%, 10%, 15%, dan 20% tidak berpengaruh nyata (P>0,05) terhadap bobot hidup, bobot karkas, dan lemak abdominal ayam joper umur 8 minggu. Substitusi daun singkong terfermentasi Aspergillus niger hingga taraf 20% masih dapat ditoleransi oleh ayam joper, akan tetapi belum mampu dalam meningkatkan bobot hidup, bobot karkas, dan lemak abdominal ayam joper.
