Contamination Analysis of Escherichia coli on Broiler Chicken Meat in Traditional Markets of Medan City

Escherichia coli (E. coli) is a gram-negative bacteria that can reduce meat quality and cause diarrhea if the amount is too much. This study investigates the presence of E. coli contamination in chicken meat sold in traditional markets in Medan. This research was conducted using the purposive sampling method and collected samples from 30% of each nine traditional markets with 32 samples. The traditional markets in Medan, namely Petisah, Central, Sei Kambing, Kampung Lalang, Kwala Bekala, Helvetia, Kampung Baru, Kemiri and Padang Bulan. Research was conducted by using the CFU / ml method with chromocult media. Samples were analyzed in the laboratory of the Regional Veterinary Disease Investigation Center Region 1 Medan. The results showed 32 samples of chicken meat had exceeded the maximum limit of microbial contamination. The highest total microbial average was in the Kampung Lalang market, 3.49 Log CFU / g, and the lowest was in the Kemiri market of 2.79 Log CFU / g. Based on the research results, it was found that the meat in the traditional markets of Medan was all contaminated with E. coli and had passed the maximum limit of bacterial contamination

Use of Cattle Rumen Fluid in Moringa Leaf Flour Fermentation (Moringa oleifera l.) to Improve the Performance of Laying Quail (Coturnix coturnix japonica)

Moringa leaf flour is a plant that contains good nutrients and high antinutrients. One of the efforts to degrade crude fiber and detoxify antinutrients through fermentation with cattle rumen fluid. This research aims to determine the effect of fermented Moringa leaf flour with cattle rumen fluid on feed consumption, body weight gain, feed conversion female quail grower phase, and age at first egg-laying. This research was held at the Livestock laboratory of Animal Science Study Program, Faculty of Agriculture, Universitas Sumatera Utara, from February to March 2024. The design experiment used a completely randomized design with 4 treatments and 5 replications, where each plot contained 5 female quails. Treatment were consisted of T0 (100% commercial feed), T1 (96% commercial feed + 4% fermented moringa leaf flour), T2 (92% commercial feed + 8% fermented moringa leaf flour) and T3 (88% commercial feed + 12% fermented moringa leaf flour). The results showed that the effect of using fermented moringa flour with cattle rumen fluid mixed with commercial feed was able to affect the performance of laying quail, with the best treatment is T2 (92% commercial feed + 8% fermented moringa leaf flour)

The Use of Various Media on Hatchability, Hatching Time and The Vitality of Honey Cricket Tillers (Gryllus mitratus)

Crickets are the most demanded commodity because there have the most interest in ornamental livestock such as birds, while the presence of crickets in nature has diminwashed because their natural habitat has been increasingly eroded by city development. The important thing to consider in cricket farms was when incubating cricket eggs which requires special treatment to maintain their temperature and humidity. Thwas study aims toknow the hatching ability of cricket, egg hatching duration and the vitality of honey cricket age 0-10 days, in different media. The research was conducted at the Biology Laboratory of Animal Husbandry Study Program, Faculty of Agriculture, Universitas Sumatera Utara, Jl. A. Sofyan No. 3 Medan, which started from November 2018 until December 2018. The design used was a completely randomized design (CRD) 4 treatments (Q0: river sand hatch media; Q1: sand hatch media; Q2: kapok hatch media; Q3: rice straw hatch, and 5 replications (each conswasting of 100 honey cricket eggs Grylus mitratus).The use of various media for honey cricket hatching eggs has a positive influence on the hatchability of eggs, the duration of hatching eggs and the vitality of honey crickets tillers. River sand hatching media (P0) is the best hatching media for the parameters of hatching eggs of honey cricket and the vitality of honey crickets tillers

THE USE OF CASSAVA PEEL (Manihot utilisima) FERMENTATION IN THE RATION ON THE FAT OF MALE LOCAL SHEEP

ARI ANDANI NASUTION, 2018: The Use Of Cassava Peel (Manihot Utilisima) Fermentation In The Ration On The Fat Of Male Local Sheep Under supervised by HASNUDI and NURZAINAH GINTING. This study aims to determine how much influence the use of cassava peel (Manihot utilisima) fermentation in the rations on fat percentage of male local sheep. The research was conducted at the farm of Mr. Praditya located in Medan, in September-December 2017. The treatmen design used Completely Randomized Design (RAL) with 4 treatments and 5 replications. Using 20 local rams with an average of 10.18 ± 1 kg. The treatment provided is P0 (Cassava peel Non Fermentation), P1 (Cassava peel Fermentation 20%), P2 (Cassava peel Fermentation 40%), and P3 (Cassava peel Fermentation60%). The results showed that the average the percentage of subcutaneous fat of sheep of highest P3= 2.04 dan low P0= 1.10 (kg/head). Average percentage of abdomen fat of highest P0= 2.364 and low P3= 2.148 (kg/head). Average percentage of heart of highest P0P2P3= 0.204 and low P1= 0.198 (kg/head). Average percentage of kidneys fat of highest P2= 0.300 and low P0= 0.24 (kg/head). Average percentage of pelvis fat of highest P3= 0.284 and low P0= 0.262 (kg/head). The conclusion of this research is the high use of fermented cassava peel in the ration can increase the percentage of subcutaneous fat and percentage of pelvis fat, butcauses the percentage of abdo men fat percentage of heart, and percentage of kidneys fat

Influence of unconventional monetary policy on agricultural commodities futures: network connectedness and dynamic spillovers of returns and volatility

Our research examines connectedness landscape and the dynamic spillovers of volatility and returns in the network comprising eleven agricultural commodities and US shadow short rate in a quality of inflation indicator, observed in monetary policymaking. We use daily data from November 2000 to May 2021. We document monetary policy as a net transmitter of spillover for both return and volatility of agricultural commodities. We find significant volatility connectedness among agricultural commodities. The connectedness is shown to be of a time-varying nature, exhibiting considerable increases during periods of market turmoil. The results of this paper provide relevant insights into the interrelations of US monetary policy and agricultural commodity prices, being, hence, potentially useful for commodity investors, brokers and dealers, as well as for market regulators designing policy solutions for financial stability enhancements

Percentage of Local Sheep Carcases: Feed by Fermented Cassava Peel

This study aimed to determine the effect of giving various doses of fermented cassava peel by local microorganisms (MOL) on the percentage of carcasses of local male sheep. The research was carried out at Mr. Praditya Raharja's Ranch, Jalan Bunga Rinte, Simpang Selayang, Medan, from December 16, 2019 to March 8, 2020 using a completely randomized design (CRD) with 4 treatments and 5 replications. This study used 20 male local sheep with an average initial body weight of 12.59 ± 1.22 kg. The treatments were: P0 (without fermented cassava peel in the ration), P1 (25% fermented cassava peel in the ration), P2 (50% fermented cassava peel in the ration), and P3 (75% fermented cassava peel in the diet). ration). The parameters studied were final weight, slaughter weight, empty body weight, and carcass percentage. The results showed that the application of cassava peel fermented by MOL in the ration had no significant effect (P>0.05) on the final weight (P0=26.17 kg/head, P1=23.34 kg/head, P2=24.50 kg/head, P3=23.43 kg/head), slaughter weight (P0=26.10 kg/head, P1=22.67 kg/head, P2=24.23 kg/head, P3=22.38 kg/head), body weight empty (P0=18.81 kg/head, P1=17.20 kg/head, P2=18.37 kg/head, P3=16.64 kg/head), carcass weight (P0=11.31 kg/head , P1=9.55 kg/head P2=10.15 kg/head, P3=9.27 kg/head), and carcass percentage (P0=60.17%, P1=55.16%, P2=55, 17%, P3=55,70%). The conclusion of this study was that giving fermented cassava peel to sheep still had a positive effect, as it did not reduce the body weight of the sheep's carcass and the percentage of carcass produced was more than 50%
