Abstract

This study aimed to examine the effect of supplementing the Complete Rumen Modifier (CRM) which consisted of 30% Morinda citrifolia leaf flour, 30% Camellia sinensis leaf dregs flour, 30% Ipomoea batatas leaf flour, 3% S. cerevisiae, 3% metionin and 3% sulfur on the energy metabolism of 18 local male sheep aged 6-8 months. The experimental feed consisted of ammoniated rice straw and concentrate (40:60) weighing 4% DM body weight. This study was subjected to a randomized complete block design (RCBD), analyzed six groups of initial weight of sheep allotted into three treatment groups: 0%, 1%, and 2% CRM of DM feed. The measured variables were energy intake (EI), digestible energy (DE), metabolizable energy (ME), energy retention (RE), and efficiency of RE to EI, RE to DE, and RE to ME. The results showed significant effects (P<0.01) of supplementing CRM in the feed on EI, DE, ME, RE, and efficiency of RE to EI, RE to DE, and RE to ME. The orthogonal polynomial test revealed that a higher dose of CRM supplementation in the feed has quadraterally increased (P<0.01) EI, DE, ME, and RE with peak points on 0,62%; 0,80%; 1,05%; 1,09%, respectively, and linearly increased (P<0.01) the efficiency of RE to EI, RE to DE, and RE to ME. It was concluded that the addition of CRM at the level of 2% was able to produce optimal energy efficiency in sheep.

Abstract

Increasing the population and productivity of dairy cows is one of the way to boost national milk production capacity. This study was aimed to determine and investigate the performance of milk production and reproduction of Friesian Holstein (FH) dairy cows in the Working Area of KPBS Pangalengan, Bandung Regency. This research used FH dairy cows with a complete milk production and reproduction record. In total, there were 90 heads of cows in the Pangalengan District and 178 heads of cows in the Kertasari District. This study used the survey method to collect the data. A Multistage Random Sampling Method was used in this research. Sampling was carried out in two stages, the first stage was sampling from two sub-district locations in Pangalengan and Kertasari Districts. In the second stage, two villages were selected from each district: Pangalengan and Margamukti Villages in Pangalengan District, and Santosa and Tarumajaya Villages in Kertasari District. Farmers and their cows were chosen by simple random sampling. Data on milk production and reproduction records were obtained from farmers and their cows through direct observation and interviews related to the identity of the cattle they owned. The results showed that the average performance of the milk production characteristics of FH dairy cows was: an average milk production of 3779.2±497.48 liters/head/day, an average length of lactation of 307.8±31.30 days, and an average dry period of 72.14±21.43 days. The lactation period had a significant effect (P<0.05) on milk production. The peak of milk production was reached in the fourth lactation period. The mean of reproductive traits consisting of the first postpartum mating was 77±20.5 days, the average length of days open was 96±26.4 days, the average number of services per conception was 1.8±0.85 times, and the average calving interval was 381.05± 24.5 days. In conclusion, FH dairy cows raised in Pangalengan and Margamukti Villages, Pangalengan District, Santosa and Tarumajaya Village, Kertasari District, in the working area of Pangalengan KPBS during the Covid-19 pandemic indicated a fairly good performance of milk production and reproduction characteristics.

Abstract

The study aimed to investigate the effect of beta-mannanase supplementation on growth performance, fecal consistency, and carcass characteristics of weanling pigs. A total of 100 weaned piglets (initial body weight = 7 ± 0.5 kg) were divided into 2 dietary treatments of (T1) control diet; and (T2) beta-mannanase supplemented diet. Each treatment was replicated 5 times with a pen of 10 piglets each following a completely randomized design. Feed and water were supplied ad libitum during the 30- day feeding trial. Fecal scores per pen were determined every morning on a daily basis; 1 pig per replicate was randomly selected for carcass evaluation. The results showed that there were no significant differences (P>0.05) in feed conversion ratio, fecal consistency scores, dressing percentage, and loin eye area between T1 and T2. Treatment T1 produced a greater body weight and gained weight faster compared to T2. In conclusion, beta-mannanase supplementation did not improve growth performance, fecal consistency, and carcass characteristics in weanling pigs. The amount of beta-mannanase was not enough to degrade the non-starch polysaccharides of the soybean meal.

Abstract

The Australian Brahman Cross (BX) cattle industry is very modern. They have created a comprehensive system guided by the principles of animal welfare. The importation of BX cattle by companies in Indonesia will be bound by the Exporter Supply Chain Assurance System (ESCAS) regulations. This study aimed to evaluate the current increased price and fattening cost of feeder Brahman Cross (BX) cattle along with ESCAS additional cost on the price of slaughtered cattle and their welfare. Based on the results, the animal welfare assessment in the feedlot for 120 days were considered good, with the average value in the first month 86.40%, then in the second month 88.50%, in the third month 92.14%, and the fourth month 94.29%. Based on the calculations result of the Activity Based Costing (ABC) method in each supply chain, it is known that procurement costs, including the purchase of feeders, contributed to 94,0% of the total costs, while other costs were handling costs 2.70%, cost of ESCAS 1.56%, selling cost 1.52%, and the lowest, maintenance cost 0.24%. Therefore, to fatten Australian BX cattle, special strategies are needed, such as: optimizing stock in the feedlot; efficiency cost in feed ingredients without reducing quality; applying animal welfare rules to minimize handling costs and selecting vendors who want the lower price in providing ESCAS support facilities and establishing regular maintenance of the ESCAS supporting tools.

Abstract

This study was aimed to measure the farmers' commitment, accessibility of resources (information, capital, and assistance), and the correlation between those variables. The research method used in the current study was the survey method. The location was purposively selected in Pemalang Regency, the regency with the largest buffalo population in Central Java Province. Three subdistricts (20%) with formal and informal farmers' groups were selected, and there were Taman, Pemalang, and Belik subdistricts. One Village was selected for each subdistrict. Respondents for informal groups were taken by census method. Respondents in formal groups were taken by random sampling, and the number of respondents followed the number of informal groups. There were 136 farmers selected as respondents. (69 from each formal and informal groups). The data were analyzed using the descriptive and rank Spearman correlation methods. The results showed that the farmers' commitment of formal group and informal group members was in the moderate and low categories respectively based on the percentage score interval scaling method. Resources accessibility of formal and informal members of the farmers' group was in the low to moderate category, but the member of formal groups was slightly better. There was a strong correlation between the accessibility of resources with the commitment in the formal groups, whereas in the informal groups there was a moderate to strong correlation between the accessibility of resources with the commitment of buffalo farmers. Based on the conclusion, this study recommend that the government should assist the informal farmer group to establish formal group with the result that would increase farmers accessibility toward  information, support, and capital. That condition would increase farmers commitment to continue their buffalo farm business in Pemalang Regency.

Abstract

Indonesia is an agricultural country that certainly has the potential for agricultural waste and by-products. Some of those in Indonesia are livestock manure, coconut husk, and sugarcane molasses. Utilization of this waste is limited, which is causing various environmental problems such as environmental pollution. The study is aimed to determine the quality of organic liquid fertilizer made by raw material from goat feces-chicken excreta-coconut husk with various sugarcane molasses concentrations (P0= 0%; P1= 5%; P3= 15%; P4= 20%; P5= 25%). The fermentation was carried out anaerobically for 21 days. The parameters of temperature, pH, organoleptic (color and odor), levels of C-organic, nitrogen (N) total, phosphorus (P) total, potassium (K) total, and biological tests were observed. Biological tests were conducted in the growth of mung bean (Vigna radiata) and spinach (Amaranthus tricolor). Data were analyzed using one-way ANOVA. Variations in the addition of molasses sugarcane did not affect the liquid fertilizer's temperature and pH during fermentation. However, the treatments had positive effect on organoleptic test, C-organic, N total, P total, K total, and biological tests. The addition of 15% sugarcane molasses (P3) showed a dominating performance toward most of the parameters tested. The P3 treatment produced liquid fertilizer with a pleasant smell, and the contents of C-organic, total N, total P, and total K were 2.12%, 0.25%, 0.13%, and 0.13%,  respectively. and produce spinach as a biological test with plant height, number of leaves, leaf width, stem diameter, and root length were 21.82 cm, 6.66 sheets, 3.59 cm, 4.09 mm, and 14.67 cm, respectively.

Abstract

Research on animal feed has often focused on finding alternative feed ingredients to replace conventional ones in order to reduce feed costs. By-products from processing crops and food products have received much attention as feed alternatives because of their consistent and mass production, one of them is a waste of coffee. This research was conducted to evaluate the substitution effect of rice bran with coffee pulp meal on feed efficiency and viscera organs of broiler. The 100 broilers (Hubbard strain) and placed randomly into 4 treatments (R0 = ration with rice bran 21% + 0% coffee pulp meal; R1 = ration with 14% rice bran + 7% coffee pulp meal; R2 = ration with 7% rice bran + 14% coffee pulp meal; R3 = ration with 0% rice bran + 21% coffee pulp meal and each treatment consisted of 5 replications, five broilers each. The broilers were arranged by completely randomized design; a Tukey test was used to compare mean different of the treatments. Substitution effect of Rice Bran with Coffee Pulp Meal on ration had significant effect on decreasing feed efficiency and significantly increase the weight percentage of heart, gizzard, pancreas, and intestine (P<0.05) but had no significant on the weight percentage of caecum in broiler (P>0.05) Tukey test showed that the higher proportion of coffee hull meal the feed consumption and body gain non-significant to R0, R1 and R2. On the other hand feed efficiency of R3 significantly lower compared to R0, R1and R2. The higher the percentage of liver, gizzard, pancreas and intestine weight. However, there was no significant effect on caecum weight percentage. The conclution was: Utilization coffee pulp meal had significant effect on decreasing feed efficiency and significantly increase the weight percentage of heart, gizzard, pancreas, and intestine

Abstract

The purpose of this study was to evaluate the organoleptic acceptance on the carcass and cooked meat of broilers fed the diet containing the fermented moringa leaves and yellow corn with the addition of fish meal or none.This study used 100 broiler chicks strain MB 90 and a commercial diet CP511 Bravo (CD). The substitute feed ingredients were composted of fermented domesticated Moringa oleifera leaf(FDMOL), yellow corn (YC), rice bran (RB), top mix (TM), and local commercial fish meal (FM). The study was performed in a Completely Randomized Design (CRD) with subsampling consisting of 5 treatments, 4 replicates, and 2 subsamples. The experimental diets were C 1 = 100% CD, C 2 =84.5% CD + 7.5% YC + 7.5% RB + 0.5% TM, C 3 = 84.5% CD + 5% YC + 5% RB + 5% TM + 0.5% TM, MCR= 84.5% CD + 5%FDMOL + 5% YC + 5% RB + 0.5% TM (moringa+), and MCF= 84.5% CD + 5% FDMOL + 5% YC + 5% FM + 0.5% TM (moringa++). The results indicated that carcasses from broilers fed the moringa-base diets were significantly higher (P<0.05) yellow coloration than those fed the control diets but the panelists’ acceptances for carcass organoleptic either fresh or cooking were not significantly different (P>0.05). In conclusion, there were no impacts on the acceptance of fresh carcass characteristics(conformation, color, and odor) or cooked meat (color, flavor, and taste) from the broilers fed the diets containing the moringa leaves compared to the control.
