Abstract

This paper investigated the types of brooding technology used by egg producers in Oyo State, Nigeria and its effect on technical efficiencies of the producers. The study was carried out in two Local Government Areas (LGAs) of Oyo State with data obtained from a total of 139 egg producers (farmers). Descriptive statistics was used to profile the farmers, probit model was employed to analyse the determinants of choice of brooding management technology, Cobb-Douglas stochastic frontier function was used to estimate technical efficiency among the farmers and Tobit regression model was also employed to ascertain technical efficiency determinants. The results show that only 9.4% of the farmers used modern brooding technology and over 50% of them employed unskilled labour. Sex of the farmer (p<0.10), household size (p<0.05) and having a secondary income (p<0.05) were the significant factors influencing adoption of modern brooding technology. Farmers who adopted the traditional brooding technology were found to be 4.3% more efficient than those using modern technology. Age (p<0.00), sex (p<0.05) and production experience (p<0.05) significantly affected their technical efficiencies. It was therefore recommended that technology subsidies, adequate extension training and skill acquisition be injected into the poultry industry to improve production efficiency.

Abstract

Wheat (Triticum aestivum) is the third most important cereal crop in Nepal after rice and maize. The research is carried out during the winter season in agronomic field of the Institute of Agriculture and Animal Science (IAAS), Bhairahawa, Nepal. Sowing is carried out 28th November 2020 and 24th December 2020 on alpha lattice design with two replication of twenty wheat genotype under normal and late sowing respectively. In the late sowing condition, all genotype's performance is reduced as compared to normal sowing. Under late sown condition, high temperatures reduced the days to booting (15.64%), days to heading (14.97%), days to maturity (14.16%), chlorophyll content (15.99%), plant height (8.59%), spike length (7.03%), number of spikelet per spike (9.21%), number of grain per spike (10.6%), spike weight (15.32%), effective tiller/m2 (9.92%), thousand kernel weight (10.3%) and grain yield (22.5%). NL 1420 presented higher 4118 kg/ha and 3310.5 kg/ha yield respectively and BL 4407 presented early maturity 119.2 DAS and 100.6 DAS respectively in normal sowing and late sowing condition. In a combined environment, maximum grain yield is recorded in NL1420. The result suggested that the tolerant line against the late sowing condition can be used as genetic resource for crop improvement and promote for grain yield.

Abstract

Centella Asiatica or Pegagan is classified as one of the wild plants that has not been domesticated. The excessive usage of this plant in traditional and modern medicinal applications threatens its population and sustainability. Thus, to preserve the plant and supply the high request of this plant in agromedicinal industry, studies concerned with the growth and bioactive compounds of Pegagan cultivated under commercial field conditions are urgently needed. This study purposed to examine the bioactive components of Pegagan (especially in leaves and roots) under field conditions, including asiaticoside, madeccasoside, and Asiatic acid. The Pegagan was harvested weeks after planting (WAP). The wet and dry weights of the leaves and roots were weighted and subsequently measured for their centelloside compounds by Thin-Layer Chromatography (TLC) procedure. The results revealed that the resulting asiaticoside content in the roots (1.25%) was higher than in the leaves (0.88%). The same results were achieved for the madecassoside content where the madecasosside content in the roots was 2.23%, while the content in the leaves was 2.11%. However, contrarily, the Asiatic acid compound in the leaves was 1.10% higher than the content in the roots (0.60%). It might be attributed to a longer period of field cultivation of Pegagan that delivered adequate time for the plant to alter Asiatic acid to asiaticoside and madecasosside at a later developmental growth. Moreover, these discoveries are advantageous in defining the most proper harvest time for commercial field cultivation of Pegagan to yield the highest amount of certain centelloside compounds.

Abstract

Soy-yamghurt is fermentation product of yam-bean extract and soybean extract made by adding bacterium Lactobacillus bulgaricus, Lactobacillus acidophilus and Streptococcus thermophillus which are commonly used in the process of making yoghurt. This study aims to determine the physical and chemical characteristics of soy-yamghurt probiotic drinks. The research used a completely randomized design factorial with two factors, i.e.: ratio of yam-bean extract with soybean extract (100%:0%; 75%:25%; 50%:50%; 25%:75%; 0%:100%) and fermentation periods (4 hours; 6 hours; 8 hours). The result showed that ratio of yam-bean extract with soybean extract had highly significant effect on color test value, viscosity, moisture content, protein content, total sugar content, reducing sugar content, starch content, and glucose content. In the meantime, the fermentation periods had highly significant effect on viscosity, moisture content, total sugar content, reducing sugar content, starch content, glucose content and had significant effect on color and protein content. Interaction between the two factors had a highly significant effect on viscosity, reducing sugar content and had significant effect on moisture content. Furthermore, the interaction had no significant effect on color, protein content, total sugar content, starch content, and glucose content. The best soy-yamghurt was produced with ratio of yam-bean with soybean extract 50:50 fermented for 6 hours.

Abstract

Response of Amaranthus cruenthus to varying aeration methods (aeration of irrigation water (A1), air injection to crop root zone in soil before irrigation (A2), air injection to crop root zone in soil after irrigation (A3), and non aeration treatment (A0)) and irrigation levels (100% field capacity (FC) (W0), 75% FC (W1), 65% FC (W2) and 55 % FC (W3) were investigated. The results showed that varying irrigation as well as aeration levels had significant effects on the height of A. cruenthus while no significant difference was obtained in number of leaves across the field capacities during the growing period. The findings of this work showed that A. cruenthus was not sensitive to air treatment as expected. This is because lower number of leaves were obtained when air was either injected into the soil before or after irrigation as well as when air was injected into irrigation water at 4 and 7 weeks after planting. Plant height was maximum when no air was introduced to the plant at 4 Weeks After Planting. However, the number of leaves were highest at 65% FC throughout the growing period. The shoot, root and whole plant fresh weight were all significantly influenced by the aeration treatments but not FC except the root fresh weight. The edible yield (shoot fresh weight) was highest (48.55g) at 100% FC (W0). Also, when the irrigation water was injected with air (A1), the highest edible yield of 57.33 g was obtained. The highest Water Use Efficiency was exhibited at 100% FC (W0) while aeration of irrigation water (A1) gave the highest (26.06) Air Use E. 65% field capacity is best for planting A. cruenthus without negatively affecting the yield.

Abstract

This study was aimed to determine the growth and development of Broiler chicken carcass and components at different sex and age . The method used in this study is the Huxley Y = a x b allometric equation which is transformed into a logarithm equation Log Y = Log a + b Log X. This research was conducted in the Cage of the Animal Production Department of the Faculty of Agriculture, Halu Oleo University. The parameters observed in this study were the carcass and carcass parts. Based on the results of the study showed that the growth coefficient of male and female broiler carcasses were not significantly different (P>0.05) which meant that they had a time of early development when compared to the growth of parts of the body as a whole. The growth and development patterns of the carcasses of both male and female broiler chickens at the age of 0 - 5 weeks is relatively the same.

Abstract

Selection for traits of economic importance is crucial for improving productivity and reproductivity in livestock, including cattle. We investigated the prospects of using growth traits; viz: live-body weight (BW), absolute growth rate (AGR), relative growth rate (RGR), absolute maturing rate (AMR), and Kleiber ratio (KR) as bases for selection in Nilotic cattle, by examining the phenotypic correlations among these traits, using 125 male and 136 female calves reared under traditional husbandry system. In the experimental procedure, the heart girth (HG) and body length (BL) of each calf was measured at birth, and at the age of 2, 4, 6, 8, 10, 12, 14, and 16 months; then the BW at each age was derived, and used for estimating AGR, RGR, AMR, KR, and dry matter intake for maintenance (DMIm). AGR, RGR, AMR, or KR was calculated from 0~8 months (AGRα, RGRα, AMRα, KRα), 8~12 months (AGRβ, RGRβ, AMRβ, KRβ), and 12~16 months (AGRγ, RGRγ, AMRγ, KRγ). Phenotypic correlations were determined using the Pearson's correlation method. The results revealed that, BW, AGR, RGR, AMR, KR, and DMIm were inter-correlated. In particular, calf weaning weight (CWW at 8 months), and post-weaning AGRβ, RGRβ, AMRβ, and KRβ (all at 8~12 months` interval) were positively correlated among themselves and with post-weaning BW, but negatively correlated with birth weight and DMIm, and thus, considered the most appropriate selection indices in Nilotic cattle, since these would decrease calf birth weight, thereby reducing dystocia incidences, and increase post-weaning growth, with less DMIm. These results provide the first evidence for possible selection using growth traits to improve productive efficiency in Nilotic cattle.
