This study aimed to investigate the effect of tetramethylpyrazine (TMP) supplementation on egg production, nutrient retention and cecal microbiota diversity using 288 commercial Hy-Line brown hens as wk 75 86. Four treatments consisted TMP addition at 0 (control, basal diet), 100, 150 200 mg/kg diet. The results showed that diets supplemented with improved egg-laying rate 77 compared control, w...

Probiotics can improve growth, survival and resistance to pathogenic organisms of the cultivated species in aquaculture systems with water recirculation. However, their possible benefits on biofloc systems have been less studied. In this study, the benefits of Bacillus amyloliquefaciens bacterium, on a biofloc culture of Litopenaeus vannamei were evaluated. B. amyloliquefaciens was applied as d...

One alternative to increase production is maximize the use of biofloc system cultivation technology. However, problems in are; difficulty cultivators replace or alternatively commercial bacteria production. efforts made bacillus sp. The aim study was determine optimal concentration sp that could growth saline tilapia. This used a completely randomized design (CRD) with four treatments, each rep...

the purpose of this study was to determine the effect of two levels of four commercial multi-enzymes on the apparent metabolizable energy corrected for nitrogen (amen) and digestibility of crude fat, crude protein, dry matter, and organic matter in broiler chickens through total excreta collection method. one hundred thirty male broiler chicks were assigned to 45 metabolic cages involving 9 tre...

We studied the effects of L-carnitine on growth performance, carcass composition, and lipid metabolism in male broilers. Six hundred male commercial broilers were allotted to five groups, each of which included three replicates (40 birds per replicate). The groups received the same basal diet supplemented with 0, 25, 50, 75, or 100 mg/kg L-carnitine, respectively. The feeding trial showed that ...

this experiment was conducted to increase the resistance of tiger barb (capoeta tetrazona ) against environmental stress by feeding brackish water gammarus sp. powder as supplementary diet in three levels (25%, 50% and 75%) and three replicates pe group compared to control group for 60 days. fishes was fed with 4 diet treatment containea of: 100% artificial diet (control group), 25% brakish wat...

this experiment was conducted to examine effects of different levels of niacin on the gut and liver histology and also some activity of the liver enzymes in the blood serum of common carp. a control diet (containing 30 mg niacin kg-1 commercial diet) and four other diets were prepared which had 50, 70, 90 and 110 mg niacin per kg of commercial diet, added by spraying. fish with initial average ...

Nutritional support is an important aspect of the management of burn patients. Nutrition supplementation can be achieved either by 'hospital-made' or 'commercial' diets. Commercial diets are efficacious but expensive and sometimes not easily available. This study was undertaken to compare the efficacy and tolerance of a hospital-made diet with a commercial diet. Twenty patients with burns rangi...
