Abstract

Six mature male Kacang goats were involved in an experiment arranged following a duplicate 3 x 3 latin square design. The objectives of this experiment was to study the effect of supplementation of dried fish as compared to fishmeal on intake, digestion, rumen environment and nitrogen use by the local meat type kacang goats maintained on urea-treated low quality grass hay. The treatments were G: goats were fed with ad libitum access of urea treated grass hay and 100 g/d putak, SDF: G plus 18.4 g sun dried fish, and FM: G plus  19.7 g/d fishmeal. The supplement in SDF and FM was at equal CP level. Intake of urea treated grass hay tended to increase (P=0.08) with supplementation. Dry matter digestibility particularly that of CP was improved by supplementation. Rumen environment was slightly modified by supplementation. Rumen pH was reduced while ammonia concentration was increased. Rumen degradation of the treated grass hay did not differ when incubated in the rumen of goats with different diets. Nitrogen balance was significantly improved (P<0.05) by fishmeal supplementation. In all parameters measured in this experiment, the incremental effects did not differ between fishmeal type. This indicate that there is no further advantage of preparing fishmeal other than sun-drying in improving the utilisation of low quality urea-treated grass hay. Keywords: kacang goats, fishmeal, intake, digestion, utilisation, rumen environment Animal Production 14(2):77-86

Abstract

The influence of concentrate during estrous cycle and pregnancy on pattern of progesterone were studied. Seventeen calf-rearing cows were devided randomly into two groups, group A (N=9 were grazed on natural pasture as basal diet, whereas goup B (n=8) received additional 2.4 kg concentrate consists of 1.2 kg corn meal, 0.6 kg rice bran and 0.6 coconut cake. Animals from each group were closely observed for estrous characteristics i.e. estrus detection two times a day by two experienced technisians. Blood sample taken 3-times per week from jugular vein were used for assessing plasma progesterone concentrations using RIA procedure. Plasma progesterone concentrations were not influenced by concentrate supplementation neither during successive estrous cycles nor during pregnancy. The concentrations began to rise on day 4 of the cycle (1.9 ng/mL and 1.8 ng/mL) and increased to concentrations as high as 5.4 ng/mL  and 5.1 ng/mL for supplemented and non-supplemented cows during the luteal phase (day 12) before returning to basal levels i.e. 0.1 ng/mL and 0.1 ng/mL, before ovulation. Following conception, plasma progesterone increased from 0,16 ng/mL and 0.21 ng/mL at estrus to 3.6 ng/mL and 2.73 ng/mL at week-1 and then rose to 5.09 and 4.57 ng/mL at week-2 for NS and S groups, respectively. Aftewards, progesterone continued to rise to 5,46 ng/mL and 5.17 ng/mL on week-3, and then reached 6.25 and 5.3 ng/mL for non-supplemented and supplemented cow, respectively. During 10 weeks pre-calving period, progesterone levels declined gradualli achieving levels 2.83 ng/mL and 2.87 ng/mL in the non-supplemented and supplemented groups, respectively, declined markedly 1 to 2 days prior to parturition and remained at these levels before reaching the basal level after parturition.

Abstract

Five non-pregnant Bali cows were used in a 5x5 latin square experimental design with the objective to study the effects of supplementation of graded levels of urea or fishmeal on fibre intake and digestion kinetics in Bali cows consuming low quality tropical grass hay. The animals were given ad libitum access to grass hay or supplemented daily with two levels of urea, i.e. 38 and 74 g, or two levels of fishmeal, i.e. 156 and 312 g. The measured parameters included were intake and apparent digestibility of DM and NDF, in sacco ruminal fibre degradation, and in vivo ruminal NDF digestion and passage kinetics. Intakes of DM and NDF were significantly improved by supplementation of both urea and fishmeal with fishmeal exerted a better effect at low level of supplementation. The increase of intake was mainly associated with the significant increase of rumen in sacco degradation of NDF. However, in vivo rumen digestions of NDF and DNDF were not significantly improved by supplementation due to the increased rumen pool of NDF after protein supplementation. As a result, rumen passage and digestion rates were not affected by supplementation. The effective level of fishmeal and urea supplementation to improve the intake of low quality fibrous tropical grass hay in Bali cows were 152 g/d and 74 g/d, respectively.
