Estimation of Bali Cattle Body Weight Based on Morphological Measurements by Machine Learning Algorithms: Random Forest, Support Vector, K-Neighbors, and Extra Tree Regression

In order to forecast and model the weight of cattle a number of techniques have been used. Nonetheless, no machine algorithm has been utilized to estimate the weight of Bali cattle. This article examines the use of machine learning regression to create models for Bali cattle's body weight prediction. The response variables consist of body weight as the dependent variable and  body length, girth circumference, height at wither of 228 male and 211 female cattle of similar ages (285 days). The descriptive statistics of female Bali cattle in our investigation revealed that the morphological measurements were similar to those documented by other researchers. To predict body weight on the basis of different characteristics, machine learning models such as Random Forest, Support Vector, K-Neighbors, and Extra Tree regressions have been used. Additionally, linear regression was utilized to estimate the body weight for comparison with the traditional approach. The assessment standards used included the determination coefficient, the root mean square error, the average absolute error, and the average absolute percentage error as measures of evaluation efficiency. We found that Linear Regression performs the best among all the regressors for female cattle. Similarly for male, it is about the same as extra tree regression. The machine learning algorithm (MLA) was discovered to furnish more precise estimate of the weight of the body cattle, surpassing the conventional algorithm

Correlation of Production (Mortality and Weight Gain) with Status and Level of Biosecurity Implemented on Layer and Broiler Farms in West Java, Bali and South Sulawesi

Biosecurity is the most effective way to prevent farms from Avian Influenza outbreak that affect most of broiler and layer farms. This paper discussed the status and level of biosecurity implemented by small and big farms (broiler and layer) in the three provinces. In addition to that is to determine if there is any correlation between mortality and weight gain to both status and level biosecurity implemented by farmers. Results showed that small layer and broiler farms have similar biosecurity status in Java and Bali but not in South Sulawesi. While small and big layer producers on both types of farms are also have similar biosecurity status in the three provinces. Regarding to the level of biosecurity implemented the three provinces has their own characteristic of implementation. Both status and level of biosecurity implemented do not have correlation on mortality in both types of farms neither on broiler weight gain

Increasing energy ration of Bali cattle to improve digestible nutrient, milk yield and milk quality

To determine the effect of energy levels on digestible nutrient, milk production and milk quality of 7 months pregnant Bali cattle, was the purpose of this study. The study was conducted in Bali, Province of Indonesia on 12 pregnant breeding phase of pre-calving (2 months before the birth) with the parent body weight 329-340 kg/head. The treatment given is four types of Metabolizable Energy (ME) levels: 2000, 2100, 2200 and 2300/kg respectively as treatment A, B, C, and D. All ration contain 10% of crude protein. Variables measured: energy intake, digestible nutrient, milk yield, and milk quality. This research is a randomized block design. The results showed that increase energy ration until 2300 kcal ME/kg would significantly (P&lt;0.05) increase energy intake and highest at cattle consumed ratio D is 22239.55 kcal/day. However, digestible nutrient was not affected. Milk production increased with increasing energy rations and highest (P&lt;0.05) at cattle received treatment D is 2179.83 ml/day compared to treatment A 936.67 ml/day. Milk fat and milk lactose also highest (P&lt;0.05) in treatment D are 8.56% and 4.76% respectively. Based on these results, it can be concluded that increase energy ration will increase energy intake, milk yield, and milk fat and milk lactose of Bali cattle

Developing a clean market chain for poultry products in Indonesia

Biosecurity on smallholder poultry farms in Indonesia is becoming increasingly important to the Indonesian poultry industry. Highly pathogenic avian influenza (HPAI- H5N1) and other poultry diseases continue to reduce poultry farm productivity, cause human mortalities and reduce consumer confidence in poultry products. Since HPAI was first diagnosed in Indonesia in 2004 (FAO 2004), it has become endemic in 31 of the 33 provinces and been responsible for 146 human fatalities (FAO 2012), the most recent in Bali in 2012
