Abstract

Penelitian ini bertujuan untuk mendapatkan level suplementasi probiotik Saccharomyces spp. G-7 dalam ransum berpengaruh terhadap bobot potong dan karkas ayam broiler umur 6 minggu.  Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan tiga perlakuan dan enam ulangan.  Variabel yang diamati adalah bobot potong, bobot karkas, persentase karkas, konsumsi protein, dan konsumsi lisin.   Ketiga perlakuan yaitu: ayam broiler yang diberi ransum tanpa suplementasi probiotik Saccharomyces spp. G-7 sebagai kontrol (A), dengan suplementasi 0,20% probiotik Saccharomyces spp. G-7 (B), dan suplementasi 0,40% probiotik Saccharomyces spp. G-7 (C).  Hasil penelitian menunjukkan bahwa suplementasi kultur Saccharomyces spp. G-7 0,20% dan 0,40% dalam ransum nyata (P<0,05) dapat  meningkatkan bobot potong, bobot karkas, persentase karkas, konsumsi protein, dan konsumsi lisin dibandingkan kontrol.  Berdasarkan hasil penelitian ini dapat disimpulkan bahwa suplementasi probiotik Saccharomyces spp. G-7 dalam ransum pada level 0,20% dan 0,40% dapat meningkatkan bobot potong dan karkas ayam broiler umur 6 minggu.

Abstract

This study aims to determine the effect of giving kelor (Moringa oleifera) leaf water extract (Moringa oleifera) through drinking water on the physical quality of Lohmann Brown chicken eggs at 22-30 weeks old. This research was conducted at farmer's chicken houses in DajanPeken Village, Tabanan District, Bali for 3 months. The design used in this study was Completely Randomized Design (RAL) with three treatments and six replications. Each replication (experimental unit) used two laying hens at 22-30 weeks old with a homogeneous weight. Treatment consisted of drinking water without addition of Moringa leaf water extract as control (Treatment A), drinking water with addition of 3% Moringa leaf water extract (Treatment B), drinking water with addition of 6% Moringa leaf water extract (Treatment C). The variables observed in this study were egg weight, percentage of egg white weight, weight percentage of egg yolk, percentage of skin weight, and skin thickness. The results showed that egg weight, egg yolk percentage, and weight percentage of egg shell, with addition of Moringo leifera water extract of 3% and 6% through drinking water which gave significant effect (P <0.05) increased and shell thickness which gave no significant effect (P> 0.05) also increased. In contrast, the percentage of egg white weight decreased compared to the chicken which was not given the addition of Moringa leaf water extract (Treatment A) as the control group. Based on the results of this study it can be concluded that the addition of Moringa oleifera water extract as much as 3% and 6% through drinking water can increase egg weight, egg yolk percentage, eggshell percentage and eggshell thickness on the contrary there is a decrease of percentage weight of egg whitesof Lohmann Brown chicken at 22-30 weeks old.

Abstract

Closed house waste which has so far been considered a contributor to environmental pollution if processed professionally, can be reused as a component of non-ruminant rations. The purpose of this study is to determine the production (potential, quantity, and quality) of broiler farm waste that is maintained in a closed house system. The cost of production of non-ruminant livestock (pig) 70-80% is still occupied by the cost of feed. The price of commercial concentrate is relatively expensive, which is a reason to look for alternative feed sources. The discovery of potential closed house chicken farm waste and innovative products as a source of protein in rations for non-ruminant (pig-poultry) is expected to the feed problem. Innovative product protein concentrate chicken farm waste of closed house (WCH) system that is cheap and competitive is produced through three stages of research: identify the type and availability of waste, its nutrient content, formulate various protein concentrate formulas, and small-scale tests on pigs with metabolic cage to determine metabolized energy content and digestibility. The results showed that the type of closed house waste (WCH) that has the potential as alternative animal feed is the waste of dead-refused chickens, and litter mixed with scattered feed. Production data in 4 periods of rearing, obtained the number of dead and rejected chickens weighing 850.7 kg (212.7 kg/period), and litter weight of 4000 kg (1000kg/period). Nutrient content of flour mixed with closed house waste (WCH), protein: 36.58%, crude fat: 4.42%, gross energy Kcal/gram. aboratory test of WCH was negative for Eschericia colli and Salmonella shigella, Coliform < 3.0 CFU/g, mold 200 CFU/g. The conclusion of this study is that the waste from closed house (LCH) broiler farms has the potential as a source of protein in alternative feeds for rumonants (chicken and pig).

Abstract

This research was conducted with the aim of knowing the effect of using protein concentrate based on broiler farm waste (KPLA) in rations on weight loss and digestive organ weight. The research used a completely randomi- zed design (CRD) with three treatments and four replications. The treatment is, A: with the use of 0% KPLA, B: with the use of 12% KPLA and C: with the use of 24% KPLA. The research used 12 pigs finisher phase with an average body weight of 66.6 ± 7.74 kg. The research parameters were body weight loss, small intestine weight and length, large intestine weight, and spleen weight. The results of the research were, after fasting for 12 hours, with the use of 0% and 12% KPLA there was a loss of body weight of 2.4% and 1.8% (P>0.05). The use of 24% KPLA (C) can increase body weight loss by 6.2%, significantly higher compared to A. The use of 0% - 12% KPLA does not cause a significant difference in the weight and length of the small intestine (P> 0.05), but with 24% KPLA (C) significan- tly reduced the weight of the small intestine by 11.9% and 11.3% in the length of the small intestine (P<0.05). The use of 0% - 24% KPLA did not affect the weight of the large intestine and the weight of the spleen (P>0.05). The conclusion of this research was the use of KPLA up to 12% did not cause significant changes in the parameters of slaughter weight, weight loss, weight and length of the small intestine. It is recommended to use KPLA in landrace pig rations up to 12%.

Abstract

Penelitian ini bertujuan untuk meningkatkan jumlah anak babi Landrace dengan menggunakan metode steaming-up (injeksi ovalumon) dan flushing (penambahan glukosa dalam ransum) pada 12 ekor babi induk. Penelitianini menggunakan rancangan acak lengkap (RAL) dengan pola percobaan faktorial 2×2. Faktor pertama (H)adalah steaming-up dengan injeksi ovalumon, dibagi menjadi dua yakni tanpa injeksi (H0) dan dengan injeksi(H1). Faktor kedua (F) adalah flushing dengan penambahan glukosa, dibagi menjadi dua yakni tanpa glukosa (F0)dan dengan glukosa (F1). Injeksi 3 ml ovalumon (2.000 i.u Estrogen) pada tiap ekor induk diberikan melalui suntikandibawah kulit belakang telinga hari ke-10 setelah penyapihan. Pemberian pakan tambahan berupa 100grglukosa dalam ransum dilakukan mulai penyapihan sampai saat induk dikawinkan. Hasil penelitian menunjukkanbahwa rataan jumlah anak babi per kelahiran (litter size) pada H0F0 (kontrol); H0F1; H1F0 dan H1F1 masingmasingadalah 4,33±0,58; 7,67±0,58; 7,00±0,99 dan 9,33±0,58 ekor. Bobot lahir anak per induk masing-masingadalah 4,10±0,38; 6,12±0,05; 5,86±0,50 dan 7,14±0,25 kg; dan bobot lahir anak per ekor masing-masing adalah0,95±0,03; 0,80±0,06; 0,84±0,07 dan 0,77±0,03 kg, serta munculnya berahi setelah penyapihan masing-masingadalah 14,67±0,58; 13,00±0,58; 12,67±0,58 dan 11,33±0,58. Dari hasil penelitian ini dapat disimpulkan bahwametode steaming-up dan flushing pada babi landrace dapat mempercepat munculnya berahi setelah penyapihananak, meningkatkan litter size, berpengaruh terhadap bobot lahir per induk dan bobot lahir per ekor.
