Abstract

This study determined the effects of different flushing frequency on performance and blood metabolite profile of ewes and their suckling lambs at pre-weaning period. Twelve multiparous Garut ewes (2 years-old, BW 30.06 ± 6.20 kg) and 18 lambs born to experimental ewes (lambing weight 2.49 ± 0.56 kg) were used in this study. Ewes were randomly assigned into four treatment groups in a complete block design, namely: without flushing (T0: control), flushing at the beginning of mating (T1: 2 weeks before and after mating), two times flushing (T2: T1 + 4 weeks flushing at mid-gestation), and three times flushing (T3: T2 + 2 weeks flushing at before and after parturition). Three times flushing increased ((p<0.05) the crude fat intake, while different flushing frequencies did not affect (p>0.05) dry matter intake and intakes of crude protein, crude fiber, nitrogen-free extract, and total digestible nutrients of ewes at the pre-weaning period. Different flushing frequencies did not change (p>0.05) the productive performances of ewes during the pre-weaning period. Flushing application improved (p<0.05) the average daily gain of pre-weaning lambs at 14 days, but it did not affect the weaning weight of lambs. Two times flushing showed no pre-weaning mortality rate (p<0.05). Flushing application tended to decrease (p=0.08) blood plasma triglyceride of ewes at 21- days, while two times flushing frequency tended to increase blood plasma cholesterol (p=0.05) and triglyceride (p=0.08) of lambs at 21 days. In conclusion, increased flushing frequency supports ewes and their twin lamb growth performance and blood metabolite profile at the pre-weaning period

Abstract

Farmers in Indonesia utilize a substantial amount of rice straw to provide feed for their livestock but restricted in terms of its low nutritional value. This study was conducted with objective to evaluate the quality of rice straw silage with addition of sacha inchi (Plukenetia volubilis L.) meal and sambung nyawa (Gynura procumbens) leaves based on physical, chemical, and microbiological properties. The study employed a completely randomized design with 9 treatments (P0: 100% rice straw, P1: 90% rice straw + 10% sacha inchi meal, P2: 85% rice straw + 15% sacha inchi meal, P3: 80% rice straw + 20% sacha inchi meal, P4: 75% rice straw + 25% sacha inchi meal, P5: P1+10% sambung nyawa leaves, P6: P2+10% sambung nyawa leaves, P7: P3+10% sambung nyawa leaves, P8: P4+10% sambung nyawa leaves) and 5 replications, incorporating the addition of sambung nyawa leaves. The variables examined include the physical quality i.e. colour, flavour, texture, and presence of mold; chemical quality i.e. pH, crude protein (CP), and crude fibre (CF); and microbiological quality i.e. lactic acid bacteria (LAB), yeasts, aerobic bacteria, and pathogenic bacteria. The results of the physical quality test indicated that the addition of sacha inchi meal and sambung nyawa leaves resulted no significant difference. On the other hand, the chemical quality showed that the addition of sacha inchi meal and sambung nyawa leaves have enhanced the rice straw silage nutritional content (p<0.05) particularly CP content by about 4 fold. The microbiological tests showed that the addition of sacha inchi meal and sambung nyawa leaves had an impact on the preservation of silage by inhibiting the growth of pathogenic microorganisms. It is concluded that the quality of rice straw silage has improved by the addition of 10-25% sacha inchi meal and 10% sambung nyawa leaves

Abstract

This study aims to determine the characteristic morphology and biomass production of Napier grass (Pennisetum purpureum) cultivar Gama Umami under teak tree (Tectona grandis) shade in teak tree forest area of Blora, Central Java. The grass was planted using stem cuttings and maintained for four months using the randomized block design (RBD) method with six repetitions in each treatment. This study consisted of two treatments, namely shade under teak tree stands and non-shade or open area as a control. Maintenance was carried out for 14 weeks with the addition of fertilizers, such as NPK (nitrogen, phosphor, and potassium) and urea. Parameters measured included plant height, leaf length, leaf width, first collar length, number of tiller, and stem diameter. After 14 weeks the plants were harvested, and biomass production data were obtained. The results showed that there were no differences in leaf length, leaf width, first collar length, number shoots, and stem diameter between under the shade and non-shade of teak trees. However, the plant height and biomass production of Napier grass cultivated in non-shade teak trees were higher than under the shade of teak trees. The finding showed that Napier grass cultivar Gama Umami could be cultivated under the shade of teak tree forest and introduce for silvopasture system in teak trees forest area.

Abstract

The quality of leather is subject to various elements, such as the specific raw material used, and the processing techniques implemented throughout the production process. Goatskin, renowned for its exceptional softness and durability, is frequently employed in the production of gloves owing to its desired attributes, notably its capacity to produce snow-white gloves. Retanning is an essential step in the leather manufacturing process as it significantly improves the characteristics of the leather. Through an investigation into the impacts of distinct retanning agents on goatskin leather gloves, this research endeavor seeks to offer significant knowledge regarding the most effective retanning procedures that can augment the tactile attributes of snow- white leather gloves. In this study, formaldehyde, alum, chromium, and chromium alum were employed as retanning agents. The retanned leathers were assessed by physical parameters, Principal Component Analysis (PCA), and Fourier Transform Infrared spectroscopy (FTIR), then compared to a commercially available snow-white leather glove. The physical characteristics of chrome alum retanned leather showed a high degree of softness (6.60±0.02 mm), good tear strength (1.530±117 N/cm), and tensile strength (1.500±100 N/cm 2 ). The principal component analysis (PCA) also supported that the properties of chrome alum retanned snow-white glove leather closely resemble commercial leather and the result from this study suggested that all factors notably impact the skin&#39;s physical quality, except for thickness. Additionally, the FTIR analysis reveals similar functional groups from the different retanned leathers indicated by comparable peaks and stretching patterns. Therefore, chrome-alum could be a well alternative retanning agent for the production of snow-white glove leather.

Abstract

The present study was aimed to investigate the effects of silo type for laboratory scale on chemical compositions, fermentation characteristics, and microbial counts of silage. Four typical silos use on a laboratory scale, consisting of transparent plastic bags (Silo A), black plastic bags (Silo B), transparent plastic bags covered with a bucket (Silo C), and transparent plastic bags covered with a sack (Silo D). All silo types were used to ensilage 5 kg Elephant grass (Pennisetum purpureum cv. Mott) for 21 d. Each Silo was conducted in triplicate. After ensiling, Silo C had higher crude protein with lower ammonia compared to other Silos (p<0.05). In addition, the Silo C resulted in lower pH, butyrate, and yeast with higher lactate and lactic acid bacteria (p<0.05) compared to other Silos. Silo C had the lowest bulginess, which indicated the optimum ensiling process. The present study concluded that ensiling forage with Silo C is more suitable and recommended for laboratory scale, which can reduce the errors, especially in the nutrient loss, production of ammonia, lactate, and butyrate, and also the counts of microbes in the silage.

Abstract

The cultivation of male laying chickens still has problems, namely the resulting performance is not maximized. Therefore research using fermented ciplukan plant (Physalis angulata) as a feed additive containing antioxidant compounds that function to improve performance needs to be carried out. This study aims to determine the effect of using fermented ciplukan flour on the performance of male laying chicken. This research was conducted at the Animal Husbandry Field Laboratory of the Faculty of Agriculture, Universitas Syiah Kuala, Indonesia. The material for this research was 100 DOC (Day Old Chicks) male laying chicken MB 502 from PT Japfa Comfeed Indonesia. This research method used a completely randomized design (CRD) with 4 treatments. The treatments were: control/without giving ciplukan (T0), giving 0.5% fermented ciplukan (T1), giving 0.75% fermented ciplukan (T2) and giving 1% fermented ciplukan (T3). Each treatment was repeated 5 times, each repetition consisting of 5 chickens. The parameters measured included ration consumption, body weight gain, final body weight, ration conversion and ration efficiency. Data were analyzed using Analysis of Variance, followed by Duncan's Multiple Range test. The results showed that the addition of fermented ciplukan flour in the ration had no significant effect on the consumption of male laying chicken. In conclusion, real treatment resulted in lower performance compared to commercial rations. However, T1, which is 0.5% ciplukan, tends to produce better performance.

Abstract

Polyunsaturated fatty acids (PUFA) supplementation in animal feed is expected to increase unsaturated fatty acids content in livestock products. Lemuru fish oil supplementation as a source of PUFA can function as a hydrogen sink to reduce methane production. The contribution of methane gas emissions in livestock reaches 15-17% of the world's methane gas emissions. Encapsulation of PUFA using natural ingredients of cinamaldehyde is expected to be a solution to increasing PUFA in livestock product and improving environmentally friendly animal husbandry. This study aimed to determine the effect of using cinnamaldehyde as an encapsulation agent for lemuru fish oil as a source of PUFA on in vitro gas, methane and CO2 productions. Treatments consisted of different levels of cinnamaldehyde, namely 0, 250, 500, 750 and 1000 (mg/kg feed DM), with the 5% lemuru oil as PUFA source. The experimental design used a one-way ANOVA in completely randomized design pattern consisting of five treatments and three replicates. Each replicate was duplicate, and then, if there were significant differences, it was continued with Duncan's New Multiple Range Test (DMRT) with SPSS version 23. This study discovered that the use of cinnamaldehyde did not affect the in vitro kinetics of gas and CO2 production. The use of cinnamaldehyde level of 500 mg/kg DM feed is the optimal level that can be used as an encapsulation agent for lemuru oil without causing an increase in methane production.

Abstract

Overcome this challenge is by participating in partnerships. However, the implementation of the partnership pattern faces challenges, particularly indiscipline in complying with the agreed-upon rules between the farmer and the nucleus company. This lack of discipline can significantly affect the success of the broiler farming business. The success of a broiler farming business is determined by various factors related to the behavior of farmers, including their knowledge, attitudes, skills, motivation, and socio-economic conditions. To understand the effect of farmer behavior on the success of broiler farming, it is essential to study the implementation of partnership patterns. This research was conducted in Central Java Province, with a focus on Banyumas Regency and Klaten Regency. Respondents were selected using the snowball sampling technique, resulting in a sample size of 90 respondents. Data were analyzed both descriptively and quantitatively, and models were constructed using the Structural Equation Modeling (SEM-PLS) method. The findings revealed that (1) the implementation of the broiler farming business partnership pattern was categorized as very good; (2) the success level of the broiler farming business was categorized as very successful; and (3) attitudes, skills, motivation, and socio-economic conditions of farmers affect the success of broiler farming toward the implementation of partnership patterns. Farmers are advised to proactively propose to partner companies to focus on improving attitudes, skills, motivation, and socioeconomic conditions that have a positive effect on business success, involving training activities, technical development, and motivational support.
