Abstract

The study was aimed to investigate the effects of restricted feeding for four weeks on some bloodchemistry and seminal parameters in kacang goats. Six adult clinically healthy male kacang goats wereused in this study. Each animal was kept in individual box for 12 weeks. Animal was fed with aerial partof peanut plant and concentrate with ratio of 60:40. The experiment was devided into two feeding periods,fullfeeding and restricted feeding. After four weeks adaptation (week 1-4), each animal was fullfed formaintenance plus medium activity (a quantity of dry matter at the level of 3% of body weight) for fourweeks (week 5-8) and then was fed only 50% of the fullfeeding nutritional level for the following four weeks restricted feeding period (week 9-12). During the experiment, drinking water was supplied ad libitum.Each animal was ejaculated at weekly intervals by means of standard artificial vagina for small ruminant.Blood and semen samples were collected at the end of the ad libitum and restricted feeding period for bloodchemistry and seminal parameters analyses. Statistical differences were determined by paired t-test. A0.05 probability level was used as criterion to describe statistically significant differences. Restrictedfeeding at the dry matter intake level of 1.5% body weight for four weeks did not result in significantchanging of serum glucose and total protein concentrations as well as seminal parameters. The level ofblood chemistry and seminal parameters during the feed restriction period were within the values reportedfor clinically healthy goats. It is concluded that feeding with a restricted quantity of dry matter at the levelof 1.5% of body weight for four weeks is not detrimental to health and reproduction in male kacang goats.

Abstract

The objective of this research was to evaluate metabolism of inorganic phosphat (Pi) and calcium (Ca) in kacang goats subjected to 60-d feed restriction and 60-d full feeding (refeeding). Nine adult male goats were divided into three groups used in this study. Restrictions include 40% (group I), 50% (group II), and 60% (group III) of the ration of dry fodder. To obtain the baseline all animals from all groups were fullfeeding from the start of the study (day 0) to day 60 then followed by restriction stage on day 61 to day 120. The next stage is refeeding from day 121 to 180. Pi and Ca levels were analyzed on days 60, 120, and 180, respectively. The results showed that restriction followed by refeeding decreased Ca levels in all three groups and Pi of animals in groups II and III was below the baseline. The level of Pi reach above the baseline were seen only in animals in group I following restriction and refeeding, although there was a tendency to decrease after refeeding. Based on the results of the study it is concluded that the restriction followed by refeeding decreases the level of Pi and Ca in adult male kacang goats. ABSTRAK Tujuan penelitian ini adalah mengkaji metabolisme fosfat inorganik (Pi) dan kalsium (Ca) selama 60 hari restriksi (pembatasan) pakan yang diikuti dengan 60 hari pemberian pakan kembali secara fullfeeding (refeeding) pada kambing kacang jantan dewasa. Sembilan ekor kambing kacang jantan dewasa terbagi menjadi tiga kelompok digunakan dalam penelitian ini. Restriksi meliputi 40% (kelompok I), 50% (kelompok II), dan 60% (kelompok III) dari 3,5% bahan kering dari bobot badan. Tahap awal sebagai baseline dimulai dengan pemberian pakan fullfeeding pada hari ke-0 sampai hari ke-60 dilanjutkan dengan tahap restriksi dimulai pada hari ke-61 sampai hari ke-120. Tahap berikutnya adalah refeeding mulai hari ke-121 sampai dengan hari ke-180. Level Pi dan Ca dianalisis pada hari ke-60, 120, dan 180. Hasil penelitian menunjukkan bahwa restriksi yang diikuti refeeding menurunkan level Ca pada ketiga kelompok dan Pi kelompok II dan III di bawah baseline. Level Pi berada di atas baseline hanya pada kelompok I setelah restriksi dan refeeding, meskipun cenderung menurun setelah refeeding Berdasarkan hasil penelitian disimpulkan bahwa restriksi yang diikuti dengan refeeding menurunkan level Pi dan Ca pada kambing kacang jantan dewasa.
