Abstract

This study aims to examine the effect of using rumen content bioactivators with the addition of different energy sources on nutrient content, fiber fraction content, and energy estimation in palm leaves and midribs that will be used as feed ingredients for ruminants.  Factorial completely randomized design 2x4 with 4 replications for each treatment was used in this study. Factor A is the source of the rumen contents, where A1 = Cattle rumen, A2 = Buffalo rumen. Factor B is a microbial energy supply; B1 = Molasses, B2 = Molasses + palm frond extract, B3 = Molasses + palm leaf extract, B4 = Molasses + palm frond and leaf extract.  Parameters observed were dry matter content, organic matter, crude protein. The results of the variance analysis showed that there was no interaction (P> 0.05) between the source of rumen content and the type of microbial energy supply. The dry matter content of palm fronds is not affected by the source of the rumen content of cows or buffaloes. The source of the rumen content based on cattle or buffaloes have no effect on the dry matter content of palm fronds. Keywords: Bioactivator, oil palm frond, ruminant.

Abstract

The development of reproductive technology for the separation of spermatozoa with X and Y chromosomes, which is better known as sexing, can be carried out in vitro using various methods, one of which is using freeze dry egg whites. This study aims to determine the quality of semen based on incubation time. This study used four types of treatment, namely P0 = No Incubation, P1 = Incubation 30 minutes, P2 = Incubation 45 minutes, P3 = Incubation 60 minutes with six replications. Parameters observed were the quality of spermatozoa macroscopically (volume, odor, color and consistency) and microscopically (motility, abnormality, concentration, intact plasma membrane, intact acrosome cap). Y using descriptive statistical test. The results of analysis of variance that sexing spermatozoa using freeze dry egg whites at different incubation times showed a significant effect (P<0.05) on intact plasma membrane (IPM), intact acrosomal membrane (IAM), but had no significant effect P>0.05) on concentration, motility, and abnormalities. Evaluation of fresh Bali cattle spermatozoa showed results that were in accordance with the standards for further examination of semen sexing. Incubation time of 30 minutes in the sexing process of spermatozoa caused a significant decrease in motility and concentration, meanwhile, IPM and IAM of sexed spermatozoa experienced a significant decrease in incubation time of 60 minutes, but the decrease was still within the normal range for spermatozoa. to be used in the artificial insemination process. Keywords:  Sexing, incubation, concentration, motility, abnormality, intact plasma membrane, intact acrosome caps.

Abstract

Goats generally have the ability to utilize carbohydrate sources from forages in the form of cellulose, hemicellulose, and pectin obtained from plant cell walls. Generally, forage contains relatively high crude fiber content which can be indicated by the contents of neutral detergent fiber (NDF) and acid detergent fiber (ADF) of the forage. The aim of this study was to examine the level of the feed consumption and digestibility of NDF and ADF of 4 different local forages fed to goats. This study was designed based on the Latin Square Design which consisted of 4 dietary treatments with 4 replications in each dietary treatment. A total of 4 male goats, with relatively the same weight and age, were randomly assigned to an individual metabolic cage fed with 4 diets including Elephant grass (R1), Mini elephant (ME) grass (R2), Panicum maximum (PM) grass (R3) and Brachiaria decumbens (BD) grass (R4). Each diet added 20% of rice bran. The results indicated that a diet containing Mini elephant grass had relatively higher digestibility of ADF and NDF compared to that of the other 3diets. In contrast, a diet containing Panicum maximum grass had lower ADF and NDF digestibility than other diets. In conclusion, adding rice bran to the diet based on Mini elephant grass, Elephant grass, and BD grass resulted in higher ADF and NDF consumption and digestibility compared with a diet based on PM grass. Keywords: Digestibility, NDF, ADF, local grasses, goat.

Abstract

Jeneponto Regency is one of the largest horse sales centers in South Sulawesi. Horse has considerable potential as a source of meat for food. Horse meat can be obtained from traders in traditional markets at a price of around IDR 150.000/kg. The preference of horse meat consumers is a person's choice of likes or dislikes towards the choice of horse meat products consumed. Consumers pay attention on various kinds of attributes attached to horse meat that are used as considerations in making purchasing decision. This study aimed to analyze consumer preferences for horse meat and the effect of consumer preferences for horse meat at Traditional Markets in Jeneponto Regency on consumer decisions. This research was carried out at traditional markets in Jeneponto Regency, namely Tolo Market and Karisa Market in December 2021. The method used in this research is a quantitative approach. The focus of this study was to reveal household consumer preferences based on horse meat attributes with a sample of 168 household consumer respondents, consisting of 100 respondents analyzed by using Cochran Q-Test analysis and 68 respondents analyzed by using regression analysis. The results indicated that there were five attributes that were most preferred by consumers, namely X1 (red liver, high fat content, lower part, cheap), X2 (brownish red, low fat content, upper part, standard), X3 (brownish red, high fat content, upper part, cheap), X4 (brownish red, no fat, lower part, standard), and X5 (liver red, no fat, lower part, standard) and the influence of consumer preferences in this case the 5 attributes that have been combined on the purchasing decisions had a significant and positive effect of 73.8%, the value of Sig. F is 0.000 so that it is less than alpha 0.05, and the t-count value of X1 (8.446), X2 (4.865), X3 (5.468), X4 (7.774), X5 (8.741) is greater than the t table value of 1.667. Keywords: Horse meat, consumer preferences, attributes.

Abstract

This study aims to analyze the reaction in the doses of cow manure and liquid organic fertilizer and their reaction to the increase of farmer's revenue in a livestock-integrated farming system in Gorontalo. This study was performed in Gorontalo from March to July 2021. The study employed a 2-factor factorial design based on the randomized block design (RBD). The first factor is the cow manure dose and the second factor is the liquid organic fertilizer dose. Data were analyzed using ANOVA and the Tukey Honest Significant Difference (HSD) test. The results of the study concluded that the most optimal cow manure dose was 10 tons ha-1 to produce maize at a rate of 5.70 tons ha-1. 20 cc/14 L liquid organic fertilizer was able to generate the most optimal production of 5,67 tons ha-1. Integrating 10 tons ha-1 cow manure with 20 cc/14 L liquid organic fertilizer can generate the most optimal production amounting to 6.83 tons ha-1.
