Beef liver and Goat Blood Waste Supplemented Diet Induced Growth Changes in Fresh Water Ornamental Fish Peacock Cichlid (Aulonocara hansbaenschi)

The growth of ornamental fishes is an important quality criterion in the aquarium fish industry. To compile and summarize recent investigations into different growth sources used in ornamental fish feed formulations and to highlight the research gaps and investigation needs in the field of aquaculture. An attempt has been made to evaluate the effects of growth by Beef liver and Goat blood waste. The fish feed at 10%, 20%, 30%, 40%, 50% and 60% diet on the growth in peacock cichlid (Aulonocara hansbaenschi). For the isonitrous (39% of protein) diets, beef liver and goat blood waste are prepared individually and offered to the candidate fish at 5% of body weight at ad libitum for a period of 40 days. The result indicates that in the skin and muscle tissue of candidate protein, carbohydrate and lipid contents were found to vary between diets and also during various intervals over experimental periods. The works of various researchers, on various fish species have led to the development of recommended inclusion levels of Beef liver and goat blood meal in the diet of the following aquaculture species. The result indicated the incorporation of 30% diet Beef liver and Goat blood waste in diet was found better to enhance the growth in peacock cichlid’s (Aulonocara hansbaenschi). Diet is considered as optimum dietary level to enhance feed intake growth.

BIOCONVERSION PROPERTY OF TEA LEAVES WASTE BY Aspergillus niger AS FUNCTIONAL FIBER TO DECREASE BLOOD LIPID

This research was aimed to find out the change of tea leaves waste fiber on lipid absorption afterbeing fermented by Aspergillus niger and also to be expected as a model to gain healthy livestockproduct. Tea leaves waste was fermented by Aspergillus niger during 6 day. Fifteen of rats with initialweight of 41.17±4.05 g were fed ad libitum by diets containing different levels of unfermented andfermented tea leaves waste as follows: basal diet (R1), unfermented tea leaves waste 5% (R2),unfermented tea leaves waste 10% (R3), fermented tea leaves waste 5% (R4), fermented tea leaveswaste 10% (R5). The results indicated that bioconversion of tea leaves waste in diet (R4 and R5)decreased almost all of fiber fractions (NDF 75.55%; ADF 57.17%; celluloses 26.74%; lignine 31.19%),except hemicelluloses 18.38%, while the treatment did not change the lipid binding rate (2.07 vs 1.98).Also, the result showed that rats fed with diets containing fermented tea leaves waste (R4 and R5) hadreduced cholesterol (86.25;87.4 mg/dl) and triglyceride (47.06; 46.03 mg/dl), but not on HDLcholesterol(29.28; 26.51 mg/dl). It was concluded that bioconversion property of tea leaves waste byAspergillus niger changed fiber fraction and decreased blood lipid.

Microbial Contamination inSpodoptera littoralisNuclear Polyhedrosis Virus Produced in Insects in Egypt

Spodoptera littoralisnuclear polyhedrosis virus produced in Egypt, for use in field trials for the control ofS. littoralison cotton, was subject to microbiological examination to quantify microbial contamination. Bacteria were found to be present at 106–109colony-forming units/ml in virus suspensions containing 2.1 × 109polyhedral inclusion bodies/ml. Batches were found to contain between 2 and 11 different species of contaminant microbes. No primary human pathogens of medical importance were found. The dominant species were fecal Streptococci and twoBacillusspecies,B. cereusandB. sphaericus.The Streptococci were derived from the normal gut flora found in healthy insects; theBacillusspecies were common opportunistic saprophytes which gained access to the product by colonizing dead larvae and diet waste. Purification methods based on centrifugation were found to be ineffective in removing bacteria and improved methods of hygiene and harvesting appeared to be of more value in reducing contamination.

Adverse effects on health of including high levels of dried poultry waste in the diets of lambs

The inclusion of 45 and 60 per cent dried battery waste in a barley-based diet of weanling lambs caused anorexia, hypoalbuminaemia, ascites, centrilobular necrosis and fibrosis in the liver after 8 weeks. The same levels of broiler waste did not produce these abnormalities, but after 16 weeks they had caused severe damage to renal tubular epithelial cells, suggesting a lowered resistance to kidney infection. Possible pathogenic mechanisms are discussed but the nature of the toxic substances present in or formed from the diets containing dried poultry wastes remains obscure.
