Abstract

The effect of oestradiol 17 B was tested in 10 buffaloes, weighing approximately 242 kg . They were fed elephant grass ad libitum plus concentrate feed at a rate of 1 % body weight, and were randomly divided into 2 groups of 5, the treated and control groups . The treated group animals were implanted with a long acting oestradiol-silicone rubber on the left ear for 200 days . Oestradiol treated-buffaloes showed a significant increase in liveweight gain (0.89 vs 0 .68 kg/d) and feed conversion ratio (9 .2 vs 11 .2) . Certainly it has a significant economic advantage in using this growth promotant . Key words : Oestradiol, feed conversion ratio, buffalo

Abstract

Faktor biologis yang menyebabkan terjadinya pertumbuhan compensatory adalah, naiknya konsumsi pakan per unit bobot badan, naiknya efisiensi penggunaan pakan dan kecendrungan menggunakan nutrien untuk sintesa protein Respons ternak  setelah diberi pakan kembali, tergantung pada umur dan tingkat berat dan lamanya pembatasan pakan.Keberlanjutan suasana hormonal atau turunnya kebutuhan pokok atau keduanya akan menentukan berlanjutnya pertumbuhan kompensatori. (Animal Production 6(2): 125-135 (2004) Kata Kunci: Pertumbuhan kompensatori, Feed Intake, Ruminansia

Abstract

Fifty samples of leaf and stem of Sorghum stipodeum, Themeda australis, Iseilema vaginiflorum, Brachyacne convergens, and Dicanthium fecundum with different stage of maturity were used to study the relationship between their chemical components and in vitro dry matter digestibility (IVDMD). The IVDMD was performed by two stage of digestion; the first stage was digestion in rumen inoculum and the second stage was digestion of protein using neutral detergent solution. The relationship between chemical components and IVDMD was analysed using regression method. There was a negative correlation between fiber component [neutral detergent fiber (NDF), acid detergent fiber (ADF), and lignin] and a positive correlation between water soluble extract (WSE) or crude protein with IVDMD. Water soluble extract was the best predictor of IVDMD with r = 0.71 and residual standard deviation of 8.4 unit. Since the method of WSE is simple and inexpensive, it can be used as a predictor of dry matter digestibility of most forages. Although there were large variation exist among the species, however, the stage of maturity was an important factor affecting IVDMD showed in four out of five species tested. In two of the five species measured, the IVDMD were higher in leaf than that in stem. Key words: in vitro dry matter digestibility (IVDMD), chemical component, forage quality, maturity

Abstract

An experiment was designed to investigate the effect of different rates of glucose infusion into animals fed a maintenance diet supplemented with undegraded protein (HCHO-casein). Twelve Merino wether Iambs were divided into 3 treatment groups receiving different rates of glucose infusion, 10 mmolelh, 20 mmolelh and 30 mmolelh. The intake and digestibility of dry matter were not affected by glucose infusion. The infusion of glucose increased N retention by reducing both faecal and urinary N. It was estimated that per unit of glucose infused, animal retained 0.15 g N/mmole glucoselh. The efficiency of N retention were 28%, 35% and 44% for glucose infusion rate of 10 mmolelh, 20 mmolelh and 30 mmolelh respectively. Urea entry rate decreased as glucose infusion rate increased. The estimation of protein spared by glucose infusion calculated from N retention and urinary excretion rate gave a value of 20 g and 25 g per 100 g glucose infused respectively. The proportion of glucose entry rate (GER) that could potentially derived from amino acids reduced as the rate of glucose infusion increased, being 21%, 17% and 14% for 10 mmolelh, 20 mmolelh and 30 mmolelh of glucose infused respectively. The GER, percentage of glucose oxidized and its contribution to CO2 production increased as the rate of glucose infusion increased. However, CO2 entry rate was not significantly affected by rates of glucose infusion. Glucose uptake by the hind-limb muscles increased with increasing rates of glucose infusion and strongly related with both GER and plasma insulin concentration. There was a tendency for circulating essential amino acids to reduce as the rate of glucose infusion increased, and was more prominent for branched chain amino acids (BCAA) at 30 mmolelh of glucose infusion. The reduction of amino acids in the blood circulation occurred concurrently with the reduction in plasma urea concentration and urea entry rate indicated increased net incorporation of amino acids into protein. Key words: Compensatory growth, glucose, N retention, amin acid
