The aim of this study was to evaluate excretion of purine derivatives and microbialâN supply in lactating Etawah crossbred goats fed with fermented soybean waste. Sixteen first lactating goats were randomly allotted into four dietary treatment groups that received 50% king grass plus R1: 50% concentrate, R2: 25% concentrate and 25% fresh tempe waste, R3: 25% concentrate and 25% fermented tempe waste, and R4: 25% concentrate and 25% gelatinizing of liquid tempe waste. Fermented tempe waste was made by fermentation of tempe waste (seed content of soybean) using Aspergillus niger, while for the gellatinizing of liquid tempe waste was made by gelatinized with maize flour. Protein balance studies were conducted during two week trial and at the end of the research. Urinary protein and purine derivatives were collected for analysis. MicrobialâN supply was calculated from purine derivatives excretion. Results showed that nitrogen consumptions were significantly different between R4 and three other treatments and apparent digestible nitrogen in R3 were higher than that of R4 (P<0.05). The nitrogen retention in R1 and R3 were higher than that of R2 and R4. Urinary purine derivatives in this study showed that allantoin, xanthine and hypoxanthine in R3 were higher than that of R4, while R1 and R2 were the same and the highest uric acid excretion and total purine derivatives were observed in R3. MicrobialâN supply were significantly different between all treatments where R3 was the highest. This research concluded that fermented soybean waste had the highest total purine derivatives excretion and microbialâN supply to the lactating Etawah crossbred goats. Â Key words: Etawah crossbred goats, Aspergillus niger, allantoin, xanthin and hypoxanthin

Plasma concentration of cortisol and hematological profile on broiler chickens can be used as heat stress indicators. This study was conducted to investigate the effect of administration of n-hexane extract of jaloh bark (EHJ) on heat-stressed broiler chicken. Thirty broilers, aged 20 days (strain Cobb), were randomly divided into 5 groups. The first group was external control (tCP) i.e. chickens without heat stress and without EHJ administration. The second group was internal control (CP) representing chickens given heat stress without EHJ administration. The third, fourth, andÂ fifth groups were chickens given heat stress and EHJ administration at doses 5, 10, and 20 mg/kg BW, respectively symbolized as CP+EHJ5, CP+EHJ10, and CP+EHJ20. The experimental broilers were exposed to heat stress in constant temperature of 33 Â± 1oC for 4 hours daily for 5 and 10 days. The EHJ was given 1 hour before temperature in the cage was raised and was given in daily basis.Â The level of cortisol in feces were measured from feces collected 1-2 hours beforeÂ treatment, 3-4 hours after heat stress exposure, and 2-3 hours after heat stress termination. This research indicated that heat stress at temperature 33 Â± 1oC during 2 and 4 hours increased cortisolÂ excretion in feces (P<0.05) and increased ratio H : L (P<0.10). The EHJ at dose of 10 mg/kg BW relatively gave more protection from heat stress impact on broilers. Key Words: Cortisol, Triiodothyronine, Heat Stress, Salix, Hematology

Nematode Ascaridia galli is an important parasitic disease in poultry and is responsible for considerable economic losses in retarded growth and lowered egg production. The effects of A. galli infection based on histopathologic description, size of small intestines villi surface and body weight change in starters was investigated. One hundred and thirty five day old chicks (DOC) were divided into three groups for three levels of infection dose rate (0,800 and 8000 infective eggs) with 3 replications of 45 DOC each. Infections were carried out every week respectively from week 2th until week 5th. Results showed that the infection of A. galli caused degeneration and necroses in villi ephitelial cells and crypts of small intestine and infiltration of leucocytes. In the heavy infection group some epithelial cells were replaced by fibrocytes. A. Â galli infection decreased daily body weight gain of starter lower (5.5% in light and 13.4% in heavy dosage infection) compared to that of the non infected group. After six weeks of heavy infection the size of small intestine villi surface was decreasing to 20.0%, while the daily body weight gain was decreasing to 12.3% compared to that of the non infection group. Key words: Ascaridia galli, Starter, Productivity

To preserve feed with enough energy has become important inaquaculture industry. A functional feed hold promises in replacing antibiotic toincrease feed efficiency. Prebiotic is one of functional feed which enhance the gutmicrobes. It was widely known that gut microflora hold an important position asexogenous enzyme producers to the host. This study accomplished with fourpellet treatments which contains feed with antibiotic and prebiotics. Themicroflora population were determined by MRSA (in Vivo) and the fish werereared for 6 weeks. The major parameter were gut microflora population (cfu/ml)andlipid deposition as the form of feed energy. The result showed that pellet withprebiotic has high performance on gut microflora and lipid deposition, whichconcluded has better feed efficiency.
