Growth performance of Rats fed different Levels of Bermuda Grass Supplemented with Lysine

Present study was conducted to evaluate the different levels of energy to protein ratios (EPR) using food waste and black soldier fly larvae meal (FWBSFL) on growth performance and nutrient digestibility of broilers. A total of 160 one-day old broiler chicks were divided randomly to four groups and each group had 8 replicates with 5 chicks per replicate. The control diet was formulated using conventional feed ingredients with EPR of 154 for the starter period and 167 for the finisher period. The other treatments were diets with normal, low, and high EPR (154,143, and 166 for the starter period; 167, 155, and 177 for the finisher period) using FWBSFL. Feed consumption and body weight gain as well as digestibility of crude protein, crude fiber, and fat were decreased due to feeding of FWBSFL diets. Different levels of EPR using FWBSFL decreased growth performance and nutrient digestibility of broilers.

ABSTRACT This study aimed to analyze the effect of water temperature on the physiological condition and growth performance of freshwater eel elver Anguilla bicolor bicolor (McClelland, 1844). This study was conducted in March 2017 at the Physiology Laboratory of Aquatic Animal, Faculty of Fisheries and Marine Sciences, Bogor Agricultural University. The study used a completely randomized design with five different levels of temperature (22°C, 24°C, 26°C, 28°C, and 30°C) as treatments with two replications. The size of elver was 2‒3 g. Fish were fed with 1 mm pellet containing 45% of protein. The feeding level was 7 % of fish biomass and the feeding frequency was two times a day. The results showed that temperatures range from 24‒30°C could be used for freshwater eel elver rearing and 28‒30°Cwere the best temperatures to support survival and growth performance of eel elver. A temperature of 24°C was the best temperature that could reduce the metabolism rate and did not cause stress on the elver.

Penelitian menggunakan rancangan acak lengkap dengan lima perlakuan suhu berbeda (22°C, 24°C, 26°C, 28°C, dan 30°C) dengan masing-masing dua ulangan. Ukuran benih yang digunakan 2‒3 g. Pakan yang diberikan berupa pellet berukuran 1 mm dengan kadar protein 45%. Jumlah pakan yang diberikan (FR) adalah 7% dari biomassa ikan dan diberikan dua kali sehari. Hasil penelitian menunjukkan bahwa kisaran suhu 24‒30°C dapat digunakan dalam pemeliharaan elver ikan sidat, dan suhu 28‒30°C merupakan suhu yang sangat baik untuk mendukung kelangsungan hidup dan pertumbuhan elver ikan sidat. Suhu media 24°C adalah suhu terbaik yang dapat menekan laju metabolisme dengan tidak menyebabkan stres pada elver ikan sidat.

Abstract. Title of the paper: Impaet of feed restriction on the growth performance of goat kids The influence of differential feeding levels on growth performance in 72 goat kids "Bunte Deutsche Edelziege" during the pre-weaning period was examined. The 72 animals were assigned to a control group and two experimental groups that received respectively 20% and 40% less milk/less concentrate compared to the control (fed at 2.4 times energy demand for maintenance). The experimental gained animals significantly less relative to the control group. However, during the subsequent realimentation period when all animals were fed at a energy level of 2.4 times maintenance same treatment, the daily weight gain among the kids was in inverse proportion to the level ofmilk deprivation in the pre-weaning phase. The rapid growth among the experimental animals was such that the initial differences in body weight between the experimental and control groups were fully compensated. Growth performance of kids with respect to different levels of concentrated feed was less clear cut and d.ffered significantly only behveen the group that received the lowest feed level relative to all the other groups.
