  The high costs of commercial concentrates limit livestock production in South-east Asia. The efficient use of local feed resources may minimize the costs and improve the productivity. Palm Kernel Cake (PKC) contains moderate levels of protein and energy, which is considered sufficient to meet the requirements of most ruminants. However, its protein degradability in the rumen is high resulting in losing its function as protein source for ruminant. This experiment was aimed to investigate the effect of feeding molasses protected PKC and soya waste on intake, nutrient digestibility and growth performance of young female goats. Eight goats were divided into 2 groups and allocated to respective feeding treatments. The treatments were T1 = napier grass (Pennisetum purpureum)+1.0% commercial pellet of live weight (LW) and T2 = napier grass+1.0% PKC of LW+100 g molasses+55 g soya waste. The results indicated that the T1 treatment increased (p<0.05) napier grass Dry matter (DM) intake (370 vs. 295 g day-1) compared to T2 treatment but the total intakes of DM (584 vs. 668 g day-1), organic matter (OM) (532 vs. 585 g day-1), Neutral Detergent Fibre (NDF) (308 vs. 344 g day-1) and crude protein (CP) (59.2 vs. 58.9 g day-1) were similar (p>0.05) for both treatments, respectively. The T1 treatment also increased (p<0.05) apparent digestibility of DM (64.1 vs. 56.3%), OM (67.3 vs. 58.9%), NDF (55.9 vs. 45.2%) and CP (68.4 vs. 52.1%) compared to T2 treatment, but they had no effect (p>0.05) on average daily gain (59.0 vs. 72.1 g day-1) and feed conversion ratio (10.4 vs. 9.6), respectively. It is concluded that supplementing a napier grass-based diet with molasses protected PKC and soya waste can be used as source of protein and energy, exploiting the use of local feed resources for goat production.

  Fresh sperm of African catfish were analysed with the aim to determine sperm movement characteristics based on individual fish body weight. Three Body Weight (BW) of fish were grouped as small (<1 kg), medium (1-1.5 kg) and large (>1.5 kg). The fish was sacrificed (euthanasia) and semen was collected by perforation of the testis. Large Body Weight (BW) of African catfish gave the highest fresh sperm total motility (82.40±4.59%) followed by medium body weight (51.64±9.82%) and small body weight (40.40±12.16%). In sperm velocity distributions, the values for rapid, medium, slow and static velocity for fresh sperm were ranged from 14.00±6.63 to 25.80±4.97, 5.60±2.32 to 15.40±2.82, 20.80±6.49 to 41.20±5.18 and 17.60±4.59 to 59.60±12.16%, respectively. The values of VAP (83.34±9.31 μm sec-1), VSL (73.44±11.60 μm sec-1) and VCL (108.12±5.51 μm sec-1) for small body weight group were significantly higher (p<0.05) than those of the large body weight group (49.70±6.42, 41.90±4.94 and 74.60±9.47 μm sec-1, respectively). It is concluded that larger body weight of the fish gives better sperm quality compared to medium and small BW.

  The necessity in detecting pregnancy particularly estimating the gestation period in goat is undeniable. This objectives of this study were to observe images of fetus and fetal-related images in goats throughout pregnancy period, to test the reliability of fetal counting using Real-time B mode ultrasound, to measure and then to compare the development of fetal heart size in both single and twin pregnancies, to compare the changes in heart echogenicity in both single and twin pregnancies in does and to estimate the accuracy of pregnancy detection as well as age related pregnancy structures using ultrasonography. Structures were detected during gestation period including sac, fetus, fetal heart, amniotic fluid, uterine wall, ribs, spinal cord, fetal organ and placentomes. Changes in fetal heart echogenicity and area throughout both single and twin pregnancy were determined and evaluated using ultrasound scanning. Equations to estimate age of gestation were derived from polynomial and linear regression between gestational age and heart area in does for single and twin pregnancies. Blind test was conducted on polynomial and linear relationships between heart area size and gestational age. For polynomial relationship, 65, 69 and 92% of pregnant does delivered within ±1, ±2 and ±3 weeks of the delivery dates, respectively. Meanwhile, linear relationship gave 62, 69 and 77%, respectively. In conclusion, sonographic fetometry of fetal heart size is reliable to estimate the age of gestation in goat.
