The Utilization of Sago Dregs to Increase Body Weight Gain and Feed Conversion Rate of Balitbangtan Superior Native Chicken

The utilization of local resource materials as the feed source for native chicken, such as sago dregs, is a potential solution to reduce the cost of conventional chicken feed. Sago dregs is produced from sago processing that is widely available in Meranti Island Regency, Riau Province. This research was aimed to determine how much evaluate the potential of sago dregs for native chicken feed in Meranti Regency. Testing sago-dregs based ration was carried out on 80 four-week-old Balitbangtan superior native chicken in four treatments (n=20) as follows: P1 = 60% fermented sago dregs (FSD)) + 10% corn + 30% trash fish; P2 = 60% FSD + 10% coffee skin + 30% trash fish; P3 = 50% FSD + 50% commercial chicken feed; P4 = 50% non-fermented sago dregs (NFSD)) + 50% commercial chicken feed. The commercial starter was given to 0-4 weeks-old chickens, while treatment feed was given to 4-12 weeks. The parameters observed were body weight gain and feed conversion ratio. The research data obtained were processed statistically using the T-test. The results showed a significantly lower (P <0.05) average body weight of chickens in P2 (630 grams) than that of P3 (808 grams) and of P4 (806 grams). Meanwhile, the P1 chickens’ weight (722 grams) was not significantly different from the others. The feed conversion ratio of P1, P2, P3, and P4 was 3.2, 3.3, 3.1, and 3.5, respectively. Sago dregs is a potential substitute for conventional feed for Balitbangtan's superior native chickens

The effect of bioplus supplementation on performance of Madura cattle in Central Kalimantan

The experiment was conducted to investigate the production performances, i.e. the growth rate, feed consumption, feed conversion and carcass percentage of Madura cattle supplemented with bioplus and palm coconut cake. Twelve (12) male Madura cattle of approximately 1.5 to 2.0 years old with an initial liveweight of 136.62+21.61 kg were used in this study, and were randomly divided into four ration treatments, namely (I) Ration composed of roughage and legume (control); (II) Roughage and legume were supplemented with bioplus; (III) Roughage and legume were supplemented with palm coconut cake; and (IV) Roughage and legume were supplemented with palm coconut cake and bioplus. Each group (unit) consisted of three cattle. The cattle were kept in feedlot system lasted in three months. The roughage and legume consisted of field grass 80%, elephant grass (Pennisetum purpureum) 10% and ground peanut straw 10%. Bioplus taken from Balitnak (Research Institute for Animal Production) Ciawi, Bogor was given at 0.5 kg/cattle and palm coconut cake was given at 2 kg/cattle, respectively. The variable measurements were average of daily gain (ADG), feed consumption, feed conversion, feed cost per gain, carcass percentage, and nutrient digestibility. The data were analyzed using a variance analyses (completely randomized design), followed by Duncan’s new multiple range test (DMRT) for the significant means. The result indicated that palm coconut cake and bioplus supplementation produce higher ADG. The ADG were 0.32; 0.38; 0.55; and 0.61 kg for treatment I, II, III, and IV, respectively. Supplementation with bioplus and palm coconut cake increased dry matter intake (DMI), organic matter (OM) and crude protein intake (CPI). Supplementation can also reduce feed conversion and feed cost per gain compared to without supplementation. Bioplus supplementation increases DM, OM, and CP digestibility. There were no significant effect of treatments on the dressing percentage, while the percentage of offal mainly skin, lung, kidney, and viscera fat were significantly different. Bioplus supplementation increased feed consumption, digestibility, and reduced feed cost per gain.   Key words: Madura cattle, bioplus, production performanc

Profile and business performance of people’s laying ducks in Harapan Mulya II farmers’ group in Bekasi Regency of West Java Province

One of the many farm enterprises in urban and rural locations is raising ducks. Duck farming provides both a source of income and a source of animal protein in the form of meat and eggs. This study aims to evaluate the performance and analysis of the laying duck business in the Pahlawan Setia Village, Tarumajaya District, Bekasi Regency, West Java Province. The study was conducted in the Harapan Mulya II Farmer Group. Surveys and in-depth interviews were used in the investigation. It was found that there are two main types of farmers in the duck industry: large-scale farmers with flocks of 1,000–2,000 ducks and small-scale farmers with herds of 25–100 birds/household flocks. The feed ingredients are primarily rejected bread and shrimp processing wastes (SPW); the average production rate is between 40 and 55 per cent. One of the feed formulations used is 42.86% SPW and 57.14% rejected bread; the feed price was IDR 1,800/kg. It was found that the R/C value for the small-scale farmers was 1.42 and 1.31 for the large-scale. It can be concluded that the laying duck business in the Bekasi Regency region is fruitful and worthwhile

The effect of local-based feed ration on the production and quality of duck eggs in Tanjungpinang, Riau Islands

The aim of the study was to determine effect of local feed on the production and quality of duck eggs in Tanjungpinang, Riau Islands. This study was conducted in Juli 2020 in Dompak Village, Tanjungpinang City. The material of research were Mojosari duck ages 38-48 weeks and local feed (feed A, B and C). This study used a non-experimental design using a survey method. Sampling using purposive sampling method. The parameter measured were egg weight, shell weight, shell thickness, yolk color and egg production. The data obtained were then compared to the average using the Mann-Whitney test. The results showed that the ration A treatment was not significantly different from ration B (P>0,05) but both were significantly different from ration C (P0,05). The highest duck egg production was obtained from ration B, which was 80 eggs per day. The conclusion of this study is that the treatment of local feed-based rations can affect the physical quality of Mojosari duck egg

Dietary biochar as a feed additive for increasing livestock performance: A meta-analysis of in vitro and in vivo experiment

The present study aimed to evaluate the use of biochar as a feed additive on nutrient utilization and livestock performance by employing a meta-analysis method. Various in vitro and in vivo studies regarding the effects of biochar on rumen fermentation, nutrient disappearance, total gas, methane production, microbial population, feed intake, growth performance, blood constituents, nutrient digestibility and nitrogen retention were tabulated in a database. Data were analysed using the mixed model method in which the different studies were considered as random effects while the biochar addition was treated as a fixed effect. The addition of biochar reduced methane production (quadratic pattern; P &lt; 0.05), but increased the total gas production (P &lt; 0.001). Addition of biochar decreased (quadratic pattern; P &lt; 0.05) volatile fatty acids and acetic acid in the in vitro rumen fermentation data. In the in vivo data, a reduction in feed conversion ratio (quadratic pattern; P &lt; 0.05), as well as a reduction (P &lt; 0.05) in the feed intake parameters of dry matter, organic matter, crude protein, and neutral detergent fibre were observed with biochar addition. Ammonia production and propionic acid tended to increase linearly (P &lt; 0.05) with the biochar supplementation. The biochar supplementation increased (P &lt; 0.05) the nutrient digestibility (dry matter, organic matter, crude protein, neutral detergent fibre) and nitrogen retention. In conclusion, biochar supplementation of ruminant diet modulates rumen fermentation by increasing propionic acid but decreasing methane emissions, and enhances livestock performance by increasing nutrient digestibility, growth performance as well as nitrogen retention
