- W2319329044 abstract "The objective of this research was to determine the relative growth rate of carcass and their components of Broiler Strain Cobb which were kept at different temperatures. Used 90 male broiler chickens with an average body weight 736.57±39.16 grams. “Split plot” form of the series on home treatment with three different temperatures T1 (34-36°C), T2 (29-32°C) and T3 (20-24°C) was used to analyze the date. The research used RAL basic design, every test was subject to withholding of 3 ages of 28, 35 and 42 days. The parameters studied were the relative growth rate of the chest, upper meat and bone. The results showed that the relative growth rate of carcass weight increased and followed with growth of life. At 20-24°C carcass maintenance grew faster (s>1) from the live weight growth, at all temperatures 34-36°C and 2932°C carcass growth was equal to the live weight growth (s=1), relative growth of the chest was similar with the live weight growth, at the temperature of 34-36°C, 29-32°C and 20-24°C, the growth rate of the upper (thigh) was relative with the live weight growth, which shows the value of s=1, meaning that growth is equal to the live weight growth, relative growth rate of meat at 20-24°C was more rapid than the growth of carcass (s>1), but generally at a temperature of 34-36°C, 29-32°C and 20-24°C the growth rate was same as the growth rate of carcass, (can be seen from the value s=1). The conclusion for the relative growth rate of organs is generally similar to the live weight growth and carcass weight at various temperatures of maintenance. Relative growth rate is faster than the live weight growth at temperature of 20-24°C. Relative growth rate of beef is faster than the live weight growth of carcasses at a temperature of 20-24°C. Key words: Broiler breeders, genetic improvement, environmental temperature INTRODUCTION Broiler breeders maintained, the more rapid growth, due to genetic improvement breeder results are supported by appropriate environmental factors. This rapid growth is inversely proportional to body surface area, which affects the rate of body heat dissipation, which is influenced by environmental temperature. Environment that affects the growth of broiler chickens, among others, is the temperature. Charoen Pokphand (2001) in Indonesia is lowland temperatures range between 2328°C throughout the year. Temperatures above 32°C will result in widening (dilation) of blood vessels, significantly. This condition will lead to drop in chicken blood pressure and heart work harder. If this takes place in a relatively long time, then the chicken will experience further stress the dead, caused the heart failure, sudden death (sudden death syndrome). The problems faced by broiler in tropical countries is the environmental temperature which is above the temperature thermo neutral, other than that in Indonesia there are many broiler strains circulating in the market, with properties different. The problem here is where the optimum strain maintained in the tropics such as Indonesia. The growth of livestock can be observed by changes in weight, size and shape and body composition, including changes in body components such as muscle, fat, bones and organs as well as chemical components. Growth of poultry in general is not much different from other livestock growth. The purpose of this study was to determine the growth rate of organs relative to the growth of live weight and carcass weight in broiler cob strains are maintained at different temperatures. MATERIALS AND METHODS Broiler strains used were Cobb 90 tails. Since age a day until age 21 days kept in cages with a size of 3 x 20 meters. In the phase of starter chicken maintained in brood stock (brooder), according to heat requirements, the first week of 35°C, 32-35°C into two, to three 2530°C. Since age 21 days of phase finisher or chicken experiments included in a different room temperature according to the treatment. Disinfectant material is Neo Antiseptic, Formalin and Lime oxide. Used vitamins are Vitabro, Vita stress and vitamin growth while medicines used for prevention of disease are Fluxamicyn and broad-spectrum antibiotics. ND vaccines using vaccine hatching eyes and drinking water, Gumboro vaccines A and B. Kerosene, rice husks, plastics, light bulbs. Used 3 pieces of equipment a closed cage, fans, air conditioners, thermo regulator, where food and drink, Int. J. Poult. Sci., 11 (10): 644-648, 2012 645 brooder, electric scales with a sensitivity of 0.1 gram and The boundaries of the parameters to be used in the a host of other equipment that support the maintenance of broiler chickens. This study uses three maintenance treatment with difference in temperature: high temperature (34-36°C), medium temperature (29-32°C) and low temperature (20-24°C). Each treatment was repeated 5 times, which is placed in cages consisted of cutting the age of three plots. concentrates to be used are for phase starter nutrient content Protein 20.57%, fat 1.49%, dry matter 86.79%, crude fiber 1.21%, ash 5.52% and 3705.70 kcal energy/kg and the phase of finisher nutrient content of feed is protein 18.76%, fat 2.83%, dry matter 88.52%, crude fiber 2.18%, 4.50% ash and energy 3933.62 kcal/kg (Analysis Laboratory). Research conducted at the Laboratory of Poultry/ Livestock Miscellaneous, College of Agricultural Extension (STPP) Magelang, located in the Purwosari village, District Tegalrejo, Magelang regency starting from age 21 days to harvest age 42 days. Experimental design used is the split-plot in the form of series which uses a cage with 3 kinds of different temperatures as a series of studies, using randomized complete a basic design (CRD). Three treatment enclosure temperature difference T1 (34-36°C), T2 (2932°C) and T3 (20-24°C), with Cobb broiler strains, each treatment was repeated 5 times. To obtain data on the relative growth rate analysis done cutting serial 3 times cutting, at the age of 28, 35 and 42 days. Chicken experiment included in room trials since age 21 days. To prevent heat stress, setting the room temperature gradually. The size of the study is a room 3 meters x 4 meters. At room 20-24°C is used with AC cooling trademark TCL, Room Air Conditioner Piping Kits. At room 34-36°C and 29-32°C heating of the sources used incandescent bulbs; air circulation is regulated by blower exhause. Cutting cattle performed at the age of 28, 35 and 42 days, was cut after fasted for 12 hrs. Hair removal done, without using water (to dry), further broken down to separate the organs of the body, excreta, blood, feathers, carcasses. Carcasses were separated between the flesh and bones, then each part weighed. To prevent evaporation of the separate parts of the body put in a plastic bag, the decomposition is done by using a scalpel. The parameters taken in this study were feed intake, body weight gain, live weight, carcass weight and Feed Conversion Ratio (FCR) to measure the performance of broiler chickens. Another parameter is the component that consists of carcass weight of the chest “breast part, under drumstick upper thigh and the carcasses of meat and bone, was used to measure the growth rate relative. study were as follows: 1) The weight of life, derived from chicken weighing after fasted for 12 hrs, at the age of 28, 35 and 42 days, in units of grams. 2) Weight of carcass weight to live weight minus the blood, feathers, viscera, head and neck and legs. Head and neck cut on the neck vertebrae 14, the foot is cut on the joint tibiatarsus, Blood is blood coming out after cutting, viscera consist of digestive tract and is still shipped with giblet, in units of grams. 3) The weight of meat carcasses. Organ weight of muscle, skin and fat carcasses that have been separated from the bone, in units of grams. 4) Carcass bone weight. Carcass weight of the bones that have been separated between the flesh and bone, in units of grams. 5) Chest, consisting of the sternum bone and musclerelated, in units of grams. 6) Upper or thigh, separated on the acetabulum, pelvic floor muscles, pelvic bones join together with the back, in units of grams. 7) Under the or the drumstick, cut at the joints of the femur and tibia, in units of grams. Chicken cut in serial experiments at the age of 28, 35 and 42 days, cut randomly determined. Each cutting as many is five birds per cage. Relative growth of carcass and carcass components of the variable independent is structured as follows: Carcass components relative growth rate, measured by the equation algometry temperature of maintenance, testing performed by t-test difference by comparing between tcount with ttable, which if the value tcount is greater than ttable, the growth of organs different with the carcass growth (s 1). Equation model: Y = a.X or using calculate b Log Y = log a + b log X Hyphotesis Ho: s=1 or There is no difference between the growth rate carcass relative and carcass components with life weight. Hyphotesis H1: s 1 There is difference between the growth rate carcass relative and carcass components with life weight.
