Abstract

The aim of this study was to determine the effect of the restriction of feed and the type of cage floor as well as its interaction to production performance in broiler chickens. This study will use 100 DOC (Day Old Chick) day old which consists of 90 major research and an additional 10 to see the state over crowded. The treatments consisted of two factors: The first factor restrictions on feeding consists of: (1) Without limiting the feed (ad libitum), (2) Restrictions feed 15%, and (3) skip a day (feeding hoses one day). The second factor is the type of cage floor consists of: (1) Floor-type wire cages (cage), and (2) Floor type cage litter. The result of this research showed that ad libitum, restricted feeding 15% and skip a day feeding were significantly (P £ 0.01) influence to final body weight, body weight gain, feed consumption kumulatif, and feed conversion. While type cages and interaction were no significantly (P ³ 0.05) on all variable production of broiler chicken.

Abstract

The purpose of this study were to compare the quality of spermatozoa stored at 26⁰C, 5⁰C using diluents of NaCl, 10% glucose and 5% glucose. The spermatozoa of a rooster was collected and divided into 6 parts, each 2 tubes diluted in a ratio of 1:1 using NaCl, Glucose5% and Glucose 10%, then each 3 tubes with different diluents were stored at 26⁰C and 5⁰C. Observations of motility, viability and abnormalities of spermatozoa were carried out half an hour, 1 hour after dilution, followed every 2 hours until the ninth hours. The results showed that spermatozoa stored for 9 hours at a temperature of 26⁰C with a physiological diluent of NaCl, 10% Glucose and 5% Glucose each were different (P, < 0.05) with motility 50 ± 0.0%, 42 ± 10.95. % and 34±8.94%, respectively. At storage temperature of 5⁰C for 9 hours, physiological NaCl, 10% glucose and 5% glucose were significantly different (P<0.05) with motility 58.00±10.95%, 46.00±8.94% and 38.00±, respectively. 10.95% in a row. The viability of spermatozoa at 26⁰C storage with 5% glucose diluent was better than 10% glucose and physiological NaCl (P<0.05), 58.93±1.27%, 42.93±1.48% and 33.43±1.27% , while the physiological NaCl diluent and 10% glucose were not significantly different (P>0.05). At 5⁰C storage the viability of spermatozoa in the three diluents was not significantly different, with values of Glucose 10%, Glucose 5% and physiological NaCl 52.57±5.15%, 52.21±5.02% and 48.14±8.09%, respectively. Spermatozoa abnormalities at storage temperature 26⁰C and 5⁰C for 9 hours using physiological NaCl diluent, 5% glucose and 10% glucose, were not significantly different and varied between 5 to 10%. Finally, it can be concluded that at room temperature storage less than 4 hours the quality of spermatozoa was better with 5% glucose diluent, while for cold storage beyond 4 hours the quality of spermatozoa with NaCl diluent was higher
