ABSTRACT:Gravity method has tremendously pervaded the field of geophysical exploration and thus discussed in this work. The basis for symmetric matrix data gravity interpretation is proposed. A symmetric matrix representation and pseudo-potential tensor were discussed and optimistically form a veritable tool for gravity data interpretation. The fundamental law of gravitational attraction is essential in delineating gravity data interpretation and the gravity effect or anomaly representation is evidently expressed by a finite difference matrix in the discussion. A computational extension can be done based on the symmetric matrix representation with available gravity data.

 Abstract: Corncob is a renewable energy resource that has a considerable potential to meet the energy demand in rural areas in Nigeria, especially for domestic and small scale cottage applications. Corncobs utilized were sun-dried and their moisture content was determined using ASAE standard. The residues were subjected to size reduction process and three particle sizes S₁ (4.70 mm), S₂ (2.40 mm) and S₃ (0.60 mm) were selected. The bulk density of the unprocessed materials and relaxed briquettes were determined using ASAE standard. Starch mutillage (binder) was added to the residues at 20 (B₁), 25 (B₂), and 30 % (B₃) by weight of the residue. A briquetting machine was used to form briquettes at pressures of 2.40 (P₁), 4.40 (P₂) and 6.60 (P₃) MPa with observation of a dwell time of 120 seconds. The initial, maximum and the relaxed densities of the briquettes were determined using the mould dimension, the relaxed briquette’s dimension and ASAE standard method of determining densities. Also determined were the compaction, density and relaxation ratios of the formed briquettes. Percentage axial and lateral expansions were also determined. The experimental data were subjected to regression analysis. A statistical package SPSS version 11.0 was used. The regression coefficients for the maximum density, relaxed density, compaction ratio, density ratio, relaxation ratio, axial expansion and lateral expansion are 0.72, 0.81, 0.85, 0.84, 0.77, 0.86 and 0.81 respectively. The study concluded that there is no significant difference between experimental and predicted results. Hence, all the developed models are reliable.

Abstract. Sixteen male lamb Afshari sheep (mean live weight 35±1.21 kg, 10 month of age) were used to study the effect of different levels of silage pistachio epicarp (0, 8, 17 and 25 %) on wool characteristics. The fleece weight (FW), staple length on shoulder (STS), flank (STF), back (STB) and rump (STR), true wool fiber (TW), medullated fiber (MF), kemp fiber (KF) percentage, mean wool fiber diameter (MD) and its coefficient variation (CVMD), breaking load (BL), wool tenacity (WT) and extension (E) were measured. These data were analyzed by one- way ANOVA using SAS software package. The total mean of FW; STS, STB, STF STR; TW, MF, KF;, MD, CVMD, BL, T and E of wool were 1622.2±0.2 gr, 6.20±0.26, 6.80±0.20, 6.50±0.20 and 6.90±0.20 cm, 63. 30±1.6, 8.30±1.6 and 28.40±2.5 percentage, 37.0±0.9 mu, 47.02±2.99 percentage, 7.60±0.3 kgf, 3.40±0.2 gf/tex and 31.1±1.7 percentage respectively. Although there were significant differences among treatments about FW, MF, KF, MD, BL and T. The results showed that feeding lambs with pistachio epicarp silage 25 percentage of total dry matter intake affected wool characteristics and it's effect was similar the control group.

Abstract: 400 day old chicks were distributed randomly into 4 treatments and 4 replicates in each treatment (25 birds in each replicate) and fed standard feed. The effects of different levels of probiotic in diets for 49 days were studied. Humoral immune responses were studied by conducting experiments on cellular proliferation, entry and survival of beneficial bacteria in gut, immunoglobulin titers. Mean body weight. Gain, feed intake and feed efficiency were recorded significantly (P<0.05).Immune response of chicks through study of levels of anti-body productions (even after SRBC injections) in experimental groups were also significantly different as compared with the control group (P<0.01).The bacteriological and intestinal morphology studies were showed significantly different in birds, when fed probiotics. Therefore, it can be suggested the Probiotic (Biomin Imbo) can be safely used at the rate of 0.1, 0.05 and 0.025% in starter, grower and finisher diets. The aim of the experiment was to evaluate whether selected Probiotic (Biomin Imbo) 3×10⁸ cfu/g have different immunomodulating effects in broiler chickens.

Effect of herbal feed additives on performance parameters of ruminants and especially on dairy goat; a Review

Abstract; Over 90% of the goats in the world are owned by rural households, which are characterized by poverty, low input agricultural practice, lack of modern management skills, poor feeding and housing practices, inappropriate breeding practices and inadequate adoption of technologies essential to improve the productivity. According to the FAO, the lack of drugs to treat diseases and infections causes losses of 30 to 35% in the breeding sector of many developing countries, where poor animal health remains the major constraint to breeding. There are two principle reasons behind the changes in legislation on the use of in-feed antibiotic growth promoters. The first is to try to combat the development of microbial resistance to antibiotic drugs and the consequences on human health. The second is a response to consumer pressures to eliminate the use of all non-plant xenobiotic agents from the diets of animals, so natural resources of medicine like phytomedicines can help smallholders in rural areas to manage their only income resources from diseases and mortality.
