Abstract

The purpose of the study was to determine the effects of adding rubber leaf flour (Hevea brasiliensis) to non-antibiotic growth promoter (non-AGP) commercial rations on dry matter, organic matter and nitrogen retention in native chickens. The materials used were 64 native chicken (32 male and 32 female) aged 8 weeks, non-AGP commercial ration and rubber leaf flour. The experimental design used was a Randomized Block Design (RBD) with 4 treatments and 8 replications. Grouping based on sex, and each replication unit consisted of 2 chickens. The treatment given was the addition of rubber leaf flour by 0% (P0), 3% (P1), 6% (P2) and 9% (P3) in a 100% commercial ration. The observed variables were dry matter (DM), organic matter (OM) and nitrogen (N) retention. Data were analyzed using analysis of variance, and the results showed that the addition of rubber leaf flour in the rations had no significant effect (P>0.05) on the observed variables. Retention of Dry Matter, Organic Matter and Nitrogen in treatment groups of P0, P1, P2 and P3 were respectively: 75.40, 78.45, 77.54 and 77.64%; 77.92, 78.38, 78.84 and 77.48 %; and 53.67, 57.69, 54.53 and 56.45%. In conclusion, the use of rubber leaf flour up to the level of 9% can highly enhance the retention of DM, OM and Nin native chicken, and hence it will also open and facilitate its potency as herbal feed additive as alternative to synthetic- AGP.

Abstract

Abstract White-nest swiftlet (Collocalia fuciphaga) has a high export economic value. The nest is produced from the saliva of the swiftlet. Presently, its method of producing swiftlet chick is through the natural breeding process.  Until now, white-nest swiftlet has not been cultivated so that the method of procuring Swiftlet chicks is still using the parent. Therefore, to see the prospects for the cultivation of this bird, another way is needed to procure swiftlets by incubating the eggs using an incubator and looking at the physical characteristics of the eggs. This study aims to examine the performance of white-nest-swiftlet eggs in natural and artificial hatching in producing swiftlet chicks. The method was used the descriptive analysis method and t-test. The physical characteristics obtained were an average egg weight of 1.94±0.13 g, egg diameter 13.28±0.56 mm, egg length 21.01±0.78 mm, shell thickness 0.14±0.02 mm. Artificial hatching results obtained were 83%, hatchability 44%, and hatching weight 1.37±0.13 g. Age of embryonic death obtained early: 38.5%, middle: 9.8%, late: 21%. Natural hatching resulted in 100% fertility, 100% hatchability, hatching weight 1.42±0.11 g., and 0% mortality. Artificial hatching is an alternative for developing white nest-swiftlet.

Abstract This study was conducted to determine the improvement of the Bali cattle population in smallholder farms based on the structure of population. This research was carried out from September to November 2019 at the Maiwa Breeding Center Partnership, Enrekang Regency. The type of research used was descriptive research, which we study that describes the variable condition, that are birth rates, mortality, sales, purchases, and population structure at the smallholder farm. The first stage was to collect data by direct observation in the field. The second stage was to carry out tabulation and data analysis. The results of the research were that the increased of Bali cattle at the Maiwa smallholder farm partnership in Maiwa Breeding Center in Enrekang Regency was influenced by calving rate of cows. The calving rate was founded  was 23% in 2017, 32% in 2018, and 46% in 2019, respectively. The mortality rate and sales of cattle was 6%in 2017, 4% in 2018 and 17% in 2019, respectively. The population dynamics was affected by calving rate, mortality and sales livestock in a year. Prediction of population growth increased gradually (7% a year) from 2020 to 2025 based on the population structure of Smallholder Farm in 2019. It is expected that the calving rate is at least 60% in a year. Keywords : Population dynamics, calving rate, mortality rate, birth rate, population growth

Abstract

ABSTRACT In the context of supporting the establishment of a profitable livestock business, a livestock feed industry that can supply livestock feed at a feasible price needs to be developed. Feed mill is constantly developing into large scale at the same time the increased population of broiler. The current research was carried out to determine distribution pattern, marketing margin, marketing profit, thus the efficiency of broiler feed marketing at PT. Sinar Terang Madani can be determined. This research was conducted in August-September 2021 at PT. Sinar Terang Madani through descriptive research that employed both quantitative and qualitative data. Furthermore, the data sources employed were primary data and secondary data. In this case, the data were collected through observation, interviews, and snowball sampling. Based on the research that has been conducted, it indicates that there are three forms of feed marketing distribution channels. In this case, the first distribution channel is the direct marketing from PT. Sinar Terang Madani to consumers. The second distribution channel is from PT. Sinar Terang Madani which is sold through retailers and then consumers. Meanwhile, the third distribution channel is from PT. Sinar Terang Madani which is marketed through agents and then to retailers and eventually to consumers. From those three distribution channel, the one that has the highest margin is the third distribution channel with a total margin of IDR 53,750/sack, while the lowest is the second distribution channel of IDR 35,000/sack. Furthermore, the distribution channel that has the largest marketing cost is the third distribution channel with an average total cost of IDR 3,816/sack, while the smallest is the second distribution channel with an average total cost of IDR 1,240/sack. In addition, the distribution channel that has the largest marketing profit is the third distribution channel with a total profit of IDR 46,118/sack, while the smallest is the second distribution channel of IDR33,760/sack. Based on the results obtained, it was concluded that the marketing that was done through the three forms of broiler feed distribution channels at PT. Sinar Terang Madani is considered efficient because it obtains an efficiency value between 0.2%-0.9%. Keywords: Distribution Channel, Margin, Cost, Profit, and Marketing Efficiency.

Abstract

One of the efforts to increase poultry productivity is to provide feed additives that are mixed with feed. Feed additives to replace antibiotics such as probiotics, prebiotics, and acidifiers can be used as additives to feed because of their ability to regulate digestive tract conditions. Moringa leaves (Moringa oliefera) and basil leaves (Ocimum basilicum) contain active compounds that can used to inhibit the growth and extinguish Escherichia coli and Staphylococcus aureus. The purpose of this study was to determine the effectiveness of each of the bioactive substances produced from a combination of extracts of several plants which were combined to have a greater antibacterial inhibition compared to single plant extracts. The research design consisted of 5 treatments and 4 replications with treatment P0 (positive control, namely contrimexasol), P1 (Moringa leaves 55% + Basil leaves 25%), P2 (Moringa leaves 50% + basil leaves 30%), P3 (Kelor leaves 45 % + Basil leaves 35%), P4 (Moringa leaves 40% + Basil leaves 40%). The study used RAL (Completely Randomized Design) and further tests were carried out with the BNT test at 5% level to determine the difference between each replicate. The results was indicated that the highest inhibitory power was found in Gram positive bacteria and the lowest inhibitory power was found in Gram negative bacteria. The combination of Moringa leaves and Basil leaves reaches a concentration of 55% + 25% able to inhibit the growth of Gram positive bacteria and Gram negative bacteria, so that it is possible to improve the digestive system in poultry and can inhibit the bacteria that cause diarrhea.

Abstract

The metabolizable energy (ME) value of common feedstuffs for Philippine mallard duck (PMD) need to be established to formulate specific and balance diet for PMD.  For this, the study was conducted to determine the apparent ME expressed in classical ME (AME) and nitrogen corrected ME (AMEn) of corn and rice bran for PMD. Eight PMD were used in the energy assay using the total collection method. An improvised digestibility cage was fabricated and used in the experiment modifying the basin technique in excreta collection. The homogenous wet mash of corn and rice bran were tube-fed to the PMD twice with an interval of six hours. Excreta collection was done for 54 hours from the last scheduled tube feeding. Feed and excreta samples were sent to UPLB for protein and gross energy analyses. The experiment was carried out using the Completely Randomized Design. The calculated AME and AMEn of corn and rice bran for PMD were 3.63 and 3.61 kcal/g and 1.97 and 1.95 kcal/g, respectively. Corn tends to have a higher ME value than rice bran. The ME value of corn and rice bran for PMD is greater than the data of PHILSAN, which is the reference standard for poultry and livestock nutrient requirements in the Philippines. The result show that corn and rice bran have higher energetic value for growing PMD than book values for poultry.  PMD is efficient in utilizing the energy content of corn and rice bran as manifested by the higher ME value.
