Pengaruh Sistem Pemeliharaan secara Intensif dan Semi Intensif pada Itik Magelang

Abstract

The duck was a local water poultry that originated from Magelang area. The aim of this study was to evaluate the weight and the weight of the duck eggs that are maintained intensive and semi-intensive. Hypotheses of the study that there was a difference between the body weight and the eggs weight in Magelang ducks that were maintained in intensive and semi-intensive systems. The research samples were 100 of Magelang ducks over 6 months old, consisting of male ducks 4 heads and ducks 96 heads. The observed parameters were body weight and egg weight. Samples were tested using T-test paired samples. The test results showed that the T value counts the body weight by 6.637 and the egg weight 3.242. This stateed that there was a significant difference in body weight and the weight of the eggs between the intensively maintained and semi-intensive ducks. The conclusion of the maintenance of a semi-intensive maintenance system had a great potential to increase body weight faster as 0.265 kg/head and the quantity also quality of the egg was better.

Carcass Quality, Production of Local Duck Meat and Edible Offals in Traditional Markets on Lombok and Sumbawa Islands

“…The high and low live weight of ducks was caused by several factors, including the strain of ducks [23], age, sex, type of feed [26], maintenance management (cage density, presence or absence of access to the outside cage) or natural conditions such as ambient temperature, humidity and air pressure [27]. Age differences are said to produce different live weights [20].…”

“…The difference between intensive and semi-intensive rearing systems is that the place where the maintenance and fulfillment of feed needs for ducks greatly affects the growth (body weight) and production [28]. Furthermore, it was said that the male Tegal ducks reared semi-intensively for 42 days had a bodyweight of 766.60 g, while those reared intensively were 994.28 g. Magelang ducks kept semi-intensively for 6 months had a bodyweight of 1.683 g, while the bodyweight of Magelang ducks kept intensively for 6 months was 1.683 g [26]. The results of this study illustrate that the bodyweight of local ducks slaughtered on the island of Lombok and Sumbawa island was still in the range of body weight of local ducks reared semi-intensively, which is in the range of 500-2.625 g. It is said that intensive maintenance and free-range access affect broilers' morphometrics and body weight [29].…”

“…The high and low percentage of duck carcass were caused by several factors, including live weight [11]; age, sex, type of feed [26]; non-carcass weight, and wasted parts [32]; maintenance management (cage density, whether or not there is access outside the cage), or natural conditions such as ambient temperature, humidity, and air pressure [27]. It was explained that differences in feed composition (protein content) would produce different carcass percentages [33].…”

“…Sistem pemeliharaan yang dilakukan di lokasi penelitian banyak dilakuan secara intensif dan semi intensif. Pemeliharaan intensif yaitu ternak dipelihara dengan dikandangkan bertujuan untuk peternak dalam pengawasan dan pemberian pakan sedangkan pemeliharaan semi intensif yaitu pemeliharaan ternak dilakukan dengan cara dilepas atau diumbar serta dikandangkan (Rahayu, et al 2020).…”

Status Hematologis Ayam Ras Petelur yang Dipelihara secara Intensif dan Free-Range pada Musim Hujan

“…Terdapat dua jenis sistem pemeliharaan dalam manajemen pemeliharaan ayam ras petelur yaitu pemeliharaan secara konvensional intensif dan free-range. Pemeliharaan intensif yaitu pemeliharaan yang dilakukan dengan cara dikandangkan dengan tujuan untuk memudahkan dalam pemberian pakan, dan untuk meminimalisir dari predator lain (Rahayu, Ratnawati, Idayanti, Santoso, & Luthfiana, 2020), sedangkan sistem pemeliharaan free-range membiarkan ayam melakukan perilaku alami mereka, meningkatkan kualitas telur dan keamanan pangan (Yilmaz Dikmen, Ipek, Şahan, Sözcü, & Baycan, 2017). Menurut Fitra et al (2021) sistem free-range adalah salah satu model pemeliharaan ayam yang sesuai dengan konsep animal welfare.…”
