There is a worldwide demand for phenolic compounds (PC) because they exhibit several biological activities. This work aimed at extracting phenolic compounds from peanut meal. The methods of extraction were mainly: conventional solvent extraction (traditional methods) and ultrasound assisted extraction (recent methods) and comparing their results. Peanut meal (PM) was prepared by defatting with n-hexane, and then extracted by the two previous methods. First, the conventional solvents used were 80% methanol, ethanol, acetone, isopropanol, and distilled water. Then studied Different parameters such as meal: water ratio, also the effect of temperature and the pH on the extraction process. Second, ultrasonic assisted extractions (USAE), the parameters investigated were temperature, time and speed of sonication. Finally, all the extracts were analyzed by HPLC for their phenolic contents. Results indicated that the highest extracted PC achieved by solvents was in distilled water where 1:100, Meal: Water ratio which extracted 40 mg PC / g PM at 30& 35°C. Highest extracted PC was achieved by alkaline medium at pH 12 more than acidic and neutral medium. While (USAE) at speed 8 ultrasonication and temperature 30ᵒC, extracted 49.2mg PC /g PM. Sothe ultrasound assisted extraction exhibited great influence on the extraction of phenolic compounds from peanut meal. The ultrasonic peanut extract was examined for its antioxidant, antimicrobial and anticarcinogenic activities. The antioxidant activity of PM phenolic extract prepared by ultrasonic technique, was measured by, β-carotene, and DPPH methods, and reducing antioxidant power. Results revealed values: 84.57, 57.72 and 5960 respectively. The PM extract showed different levels of antimicrobial activity against the pathogenic bacteria used. As for the anticarcinogenic effect PM phenolic extract most effective on inhibiting colon carcinoma and lung carcinoma cell lines with IC50 = 20.7 and 20.8 µ/ml., respectively. This was followed by intestinal carcinoma and liver carcinoma cell lines with IC50= 39.6 and 40.2µ/ml.

The liveweight performance and carcase characteristics of Brahman x Hereford, Africander x Hereford and Africander x Shorthorn F, crossbred spayed heifers were compared with those of local Shorthorn spayed heifers on native pasture at Katherine, N.T., between 1962 and 1965. The breed groups were divided for planes of winter nutrition, viz., with and without 2 lb a day of peanut meal from early June until the start of the wet season. Without supplement, the average weight gains of B x H, A x H, A x S, and Shorthorn cattle between June 1962 and May 1965 were 0.49, 0.37, 0.36, and 0.23 lb a day respectively. With supplement, cattle reached slaughter weight a year earlier ; the average weight gains of B x H, A x H, and Shorthorn cattle between June 1962 and May 1964 were 0.61, 0.63, and 0.50 lb a day respectively. (There was no A x S supplemented group). Without supplement, the dressing percentage and estimated proportion of fat of B x H cattle was higher and the estimated proportion of muscle and bone lower than those of other breeds. With supplement, there were no significant differences in dressing percentage or carcase composition between breeds. Measurements made of thermoregulatory attributes indicated that the local Shorthorn cattle, through body temperature control, showed adaptation to heat stress.

Five groups of Friesian bull calves were given concentrate diets containing 70 % barley in which low (12 %), medium (15 %), and high (19%) protein levels were obtained by varying the amount of peanut meal included. The effects of protein level and of formaldehyde treatment of the complete diet at the low and medium protein levels were studied in terms of liveweight gain, voluntary food consumption, digestibility of the diet, ammonia nitrogen in rumen fluid, and urea and a-amino nitrogen in blood plasma. Observations were begun when the calves reached 70 kg liveweight and continued until they reached 130 kg liveweight. The calves given the low protein diets grew more slowly than those given the higher protein diets. The calves given the high protein diet grew no better than those given the medium protein diets. Formaldehyde treatment was associated with an increase in the rate of liveweight gain of 9% (P = 0.11) at the low protein level but had practically no effect at the medium protein level. The treatment did not adversely affect voluntary food consumption but was associated with decreases in the digestibility of nitrogen and in rumen ammonia levels and small increases in plasma urea levels.

Abstract Beef chuck and plate cuts obtained from U.S.D.A. utility grade carcass were mixed and ground through a 0.318 cm plate. The ground meat was extended with extruded and non-extruded defatted peanut meal. Hydrated defatted peanut meal was added at the rate of 20 and 30 parts to 80 and 70 parts of the ground meat, respectively. All treatments were formulated to contain 20% fat in the final patty and loaf products. Extruded and non-extruded meat products were stored at −18 C for periods up to 6 weeks. All quality evaluations were conducted on cooked meat products. Ground meat patties and loaves extended with non-extruded peanut meal exhibited similar cooking losses to those either extended with extruded peanut meal or 100% beef products. Control meat products stored for 4 weeks or longer required larger forces to shear than the non-stored patties. Freezing storage of the extended meat products did not result in a change of shearing forces. These forces were similar to the shearing force exhibited by freshly prepared products. Trained sensory panelists indicated that extended meat patties were more tender and less cohesive than non-extended patties. However, sensory acceptability tests indicated similar acceptability ratings for the extended and non-extended meat patties and loaves.
