Abstract

ABSTRACT Pretreatment of chemical acids using organic chemicals has been widely applied, while pretreatment using microbial Lactobacillus plantarum to form ossein in goat skin has not been done much. Application of Lactic Acid Bacteria (LAB) microbial species L. plantarum is thought to affect health and environment friendly. This study aims to determine the characteristics of goat skin gelatin at different ages of L. plantarum 1uhcc pretreatment and acetic acid (CH3COOH). Each treatment was repeated 3 times. The study design used a Split Plot Design with acid source treatment as the main plot and the age of goats 1, 2 and 3 years as subplots. The results showed a very significant effect (P<0.01) between the age of the goat with gel strength, pH, viscosity and color. The highest gel strength and viscosity at 1 year of age with L.plantarum pretreatment respectively (441.37±0.78 g bloom) and (9.22±0.09 cP). Goat skin gelatin has the highest pH at 1 year of age with L.plantarum 5.24±0.16. Similarly, the effect of gelatin (P<0.05) with a brightness level (L) 76.38±1.10 and redness (a) 11.13±1.58 affect the age of goats and acidic sources while yellowish (b) 33.81±2.34 only affects the acid source. Age of goats with different acid pretreatment has an impact on the physicochemical properties of goat skin gelatin. Goat age 1 year with L.plantarum pretreatment showed optimal results.

Abstract

Utilization of unconventional materials such as corn tumpi and dragon fruit peel flour as an alternative feed ingredient for ruminants, especially goats. This study aims to examine the effect of providing complete feed containing corn tumpi with dragon fruit peel flour at different levels on consumption and digestibility of goats. This study used 12 local male goats with ages ranging from 1 to 1.5 years which were randomly assigned to metabolic cages. The study used a Randomized Block Design (RBD) method with 3 treatments and 4 groups. The treatments consisted of P1: Complete feed containing 50% corn tumpi, P2: Complete feed containing 45% corn tumpi and 5% dragon fruit peel flour and P3: Complete feed containing 40% corn tumpi and 10% dragon fruit peel flour. The results showed that the treatment of complete feed containing corn tumpi with dragon fruit peel flour at different levels had a significant effect (P<0.05) on dry matter consumption and organic matter consumption. Dry matter consumption ranged from 296.88 – 461.64 g/h/day, and nitrogen consumption was between 265.74 – 407.72 g/h/day. Treatment of complete feed containing corn tumpi with dragon fruit peel flour at different levels had no significant effect (P>0.05) on dry matter digestibility and organic matter digestibility. Dry matter digestibility ranged from 82.75 – 87.50 %, and organic matter digestibility between 84.5 – 88.75 %. It was concluded that based on estimates of dry matter consumption and organic matter consumption, the use of alternative ingredients for corn tumpi with dragon fruit peel flour up to a level of 10% could be used as a complete mix of feed ingredients for ruminants, especially goats.

Abstract

The limited forage availability in the dry season is a limiting factor in a livestock business. The abundance of forage in the rainy season cannot be stored long without treatment. This is due to the high water content, so forage cannot be stored; there is a need for innovative feed technology. Silage is a feed processing technology using a method of preserving/fermenting feed in anaerobic conditions, which is placed in a silo with a water content of around 60-70%. The principle of forage fermentation is by microbes that produce a lot of lactic acid. This research aimed to determine corn straw silage's physical properties (organoleptic tests) by adding several types of legumes. According to data from the Directorate General of Animal Husbandry and Animal Health in 2022, the number of cattle in South Sulawesi Province was 18,610,000 head. The increase in production in 2022 compared to 2012 occurred in all regions in Indonesia, South Sulawesi Province.  Corn produced was 1,420,154 tons, which shows that corn straw waste is abundant and can be used as forage using silage technology. The materials used are Bima Provit A1 (stay green), hybrid corn stover, and legumes. The treatments used were 95% corn stover silage (control), 70% corn stover silage + 25% Gamal legumes, 70% corn stover silage + 25% Lamtoro legumes, and 70% corn stover silage + 25% Indigofera legumes. Creating an acidic atmosphere can be accelerated by adding preservatives or additional ingredients (additives) to rice bran (5%). Organoleptic test parameters to determine silage's physical characteristics and quality, such as texture, color, and aroma. The results obtained were that the silage texture score in all treatments had an average value that was not much different and fell into the medium texture category, the silage color score in all treatments had good quality, brown and yellowish brown, the aroma score in all treatments had good quality. Keywords: Corn stover silage, leguminosae, organoleptic test

Abstract

Turmeric is a widely available herb. This study aimed to determine the effect of Turmeric (Curcume domestica) as an herbal additive in local raw material (LRM) goat rations on dry matter digestibility and organic matter digestibility, pH value, N-ammonia and, in vitro gas production. The study was conducted with a completely randomized design (CRD) of 5 treatments and three replications: treatment T0 = LRM goat ration, T1 = local feed ration (LFR) + turmeric 0.025%, T2 = LFR + turmeric 0.05%, T3 = LFR + turmeric 0.075%, T4 = LFR + turmeric 0.1%. Variance analysis showed that the effect of turmeric (Curcuma domestica) in goat rations made from LRM local has a significant impact (P<0.05) on dry matter digestibility (DMD) and organic matter digestibility (OMD). The most considerable N-ammonia value was obtained in treatment T1, which was 21.13 ± 1.29. From the results obtained, each treatment had a significant effect (P<0.05). The provision of turmeric in goat rations showed promising results regarding the value of rumen N-ammonia. The pH value produced in this study was 6.09 to 7.00, with no significant effect because the pH in the rumen has been maintained. Keywords: Feed additive, turmeric, pH, N-ammonia, in vitro
