Abstract

 Abstract The research aims to determine the growth pattern of alfalfa in the tropical region, which later can be used as a source of information for the people needed. Research methods used are experimental; the data acquired during the 90 days was showed in a graph and then analyzed using regression analysis with two variables, namely independent variables (cutting age) and dependent variables (the nutritive value, height of plants, and production of dry matter (DM), organic matter (OM), and crude protein (CP)). The growth pattern of alfalfa in the range 20 to 90 days was quadratic, with the equation of y= -0.0092x2 + 1.6113x – 19.257. At that range of time the alfalfa was still in vegetative growth phase. With increasing age of cutting, the alfalfa chemical compositions of DM and OM increased, but the content of CP decreased.While the production of DM, OM, and CP increased with increasing cutting age. Key words: nutrition, growth, alfalfa, tropics

Abstract

This study obtained morphometric information on Galekan cattle and compared phenotypic characteristics of Galekan cattle with local breed based on previous studies. This research was a case study with purposive sampling using the snowball sampling technique. The material used was 60 cattle of Galekan cattle which were kept in the Technical Unit (UPT) at Dongko and Panggul Sub Districts. The variables observed included qualitative characteristics and quantitative characteristics of morphometric components and body weight. T2-Hotelling test, descriptive statistics, and principal component analysis are used for quantitative data. The results showed that the qualitative characteristics of Galekan cattle were dominated by light brown body color with smear body color border, black backline, black vulva, black tail tip, face color as same as dominant body color, black muzzle, black upper and lower lips, smear white eye area, dark eye circles, black eyelashes, and black ear lines. The characteristics of the body shape of Galekan cattle have upward horns, no hump, and thin dewlap. The results of the T2-Hotelling analysis in UPT showed a significant difference (p <0.05) compared to other cattle in Dongko and Panggul Sub Districts. Principal component analysis (PCA) of Galekan cattle can be characterized by body weight, chest girth, depth chest, Ossa vertebrae lumbales, Ossa metatarsal, and Ossa vertebrae thoracicae.

Abstract

GDFP is a standard guideline for producing good milk quality and efficient production system. GDFP implementation has been less attention among the dairy smallholder farmers. The smallholder farmers are classified into three categories depending on animal ownership; strata 1 (1-3 AU), strata 2 (4-6 AU), and strata 3 (>7 AU). This research determines the score of GDFP implementation on smallholder farmers in East Java. The total respondents were 56, with 325 dairy cattle. A questionnaire and field observations were used to collect data using the survey method. The farmers were interviewed using a prepared questionnaire with general information about their farms and questions about GDFP implementation. The result showed that the score of GDFP implementation in all strata of smallholder farmers in East Java Indonesia in 6 aspects as follows: animal health was  “good enough” (score  2.68-2.70), milking hygiene was “good” (score 3.19-3.42), nutrition was “good enough” (score 2.86-2.97) in strata I and III and “good” for strata II (score 3.03), animal welfare was “good enough” (2.56-2.60), the environment was "good enough" (2.34-2.50) and socio-economic management is “not good” (score GDFP = 1.60-1.92).

Abstract

This investigation aimed to identify the production and composition of crops as feed, classify the types of integrated farming in different locations, and compare dairy goats based on their morphometric characteristics. The data used were collected from July to November, 2021 in the Malang, Lumajang, and Bangkalan regencies of Indonesia, via a survey and direct observations. Descriptive, multivariate, and variance analyses were adopted using RStudio to analyze the collected data. In Malang and Lumajang, farmers adopted agroforestry, alley cropping, and cover crops as the main types of integrated farming. The integrated farming adopted by the farmers in Malang, Bangkalan, and Lumajang helped to explain the differences in forage crops. Calliandra calothyrsus, Indigofera zollingeriana, and Thitonia diversifolia are non-grasses having high levels of average production. In Lumajang, farmers provided only a few combinations with Calliandra which was the most intensively grown crop. In Malang, six crops were combined for the dairy goat feed. Pennisetum purpureum was the crop most intensely grown to feed the PE (Etawa crossbred). In Bangkalan, Pote-Arosbaya goats were fed a combination of eight crops. Moringa oleifera, Bambusa sp., Artocarpus heterophyllus, and natural grasses were the most popular feed crops. In Malang and Lumajang, the PE Singosari and Senduro goats had a high degree of similarity based on their morphometric characteristics, respectively.
