In this study, the effects of coat difference and breeding age on the internal and external quality of the eggs were investigated in white laying hens in different cages. The eggs obtained from a total of one hundred fifty eggs White layer pure line hens at 24, 28, 32, 36 and 40 weeks of age that housing in individual cages in the Ankara Poultry Research Institute were used. Shape Index, egg weight (g), albumen height (mm), Roche scale, Haugh unit and shell strength (N) values were examined in 438 eggs obtained from these chickens found in these cages which are three tiers as upper, middle and bottom. In addition, temperature and humidity values in the tiers were recorded at 30-minute intervals during the study and then they were analysed. Statistically significant differences were calculated between temperature and humidity values measured in tiers. Although there was no difference between the tiers in terms of shape index and egg weight, the effect of age was significant. The effect of age and tiers difference on albumen height (mm) was insignificant. The Roche scale and shell strength (N) values were significantly influenced by the tier difference and breeding age. In general, it was concluded that the effect of the tier difference on the Haugh unit was insignificant, but the age was found to have an effect on the Haugh unit.

Three hundred and thirty eggs collected from the second to the seventh month of production, from a flock of the Nigeria indigenous (NI) chickens, were analysed to determine the effect of the length of lay on egg composition and shell quality. The weights of the whole egg and its components as well as shell thickness were measured monthly while the proportion of the various components; egg shape index, shell density and shell weight per surface area were calculated. The results showed that egg weight, albumen weight and % albumen increased (P<0.05) with length of lay by 2.6g, 3.5g, 3.5g and 5.6% respectively between 2nd and 7th months. The change in the weight of the yolk, shell and egg shape index was not significant (P>0.05) between the 2nd and 7th months while % yolk, % shell, shell thickness and the shell weight per surface area decreased (P<0.05) by 4.2%, 0.64%, 0.04mm and 0.003g respectively within the same period. Strong phenotypic correlations were observed between the weights of the whole egg and the albumen (r=0.81), shell (r=0.63) and yolk (r=0.46) and also between shell thickness and its weight per surface area (r=0.81). These results indicate that egg size increased as the NI hen advanced in lay. Eggs laid in the 6th and 7th months contained more albumen than those laid earlier and the shell thickness decreased as the hens advanced in lay thus making them more liable to breakage.

Introduction: The body roundness index (BRI) and a body shape index (ABSI) are novel anthropometric indices established to determine both the amount visceral adipose tissue and body fat. Objective: to investigate whether BRI and ABSI are better predictors of hypertension than body mass index (BMI), waist circumference (WC) or waist-to-height ratio (WHtR). Methods: A systematic search was conducted in the Scopus, PubMed and Web of Science databases up until 31 December 2020. Results: The estimated pooled area under curve [AUC (95% CI)] for BRI [0.67 (0.65–0.70)] for the prediction of hypertension were superior to that of ABSI (0.58 (0.56–0.60)), similar to that of BMI [0.67 (0.64–0.69)], and lower than those WC [0.68 (0.66–0.70)] and WHtR [0.68 (0.66–0.71)]. Nevertheless, the difference of BRI compared to WC and WHtR in the context of predicting hypertension was non-significant. ABSI was significantly lower (p < 0.05) than BRI, BMI, WC and WHtR. Similar findings were observed with the summary receiver operating characteristic curve (AUC-SROC). There were no significant differences between subgroups according to type of population or diagnostic criteria of hypertension. The diagnostic odds ratio (dORs) proved that increased BRI and ABSI were related with an elevated hypertension risk. Conclusions: BRI and ABSI have discriminatory power for hypertension in adult women and men from different populations. Although, WHtR and WC provided the best performance when assessing hypertension, no significant differences were found for BRI. Finally, BRI was significantly better predictor of hypertension than ABSI.

The Red Wattled Lapwing is an important bird of the agro-ecosystem of the Punjab state, feeding on insects, seeds and nectar. The present study was carried out to gather information on the egg parameters (morphometry and its components), which is lacking for this species. The eggs were observed in the nest construct-ed in the agricultural fields of Punjab Agricultural University (PAU), Ludhiana, Punjab. Egg length, width and weight were measured using vernier caliper and portable weighing balance, respectively, in laboratory. The egg parameters like egg volume, specific gravity and shape index were also calculated. Weight of egg components (yolk, albumen and shell) were also measured using weighing balance. Results revealed that average values of egg breadth, length and shape index were: 30.05±0.331 (mm), 41.29±0.573 (mm) and 72.83±0.930, respectively. Whereas whole egg weight, albumen weight, yolk weight, shell weight, albumen percentage, yolk percentage, shell percentage, egg volume and specific gravity were 17.49±0.634(gm),7.17±0.374 (gm), 9.05±0.233 (gm), 1.26±0.070 (gm), 40.84±0.941 (%), 51.92±0.830 (%), 7.22±0.280 (%), 17.07±0.531(cm3) and 1.02±0.009 (gm/cm3), respectively. This study pro-vides important information that can help the avian taxonomists in species classification, as bird’s egg diverges widely in shape, volume, weight and percentage of albumen, yolk and shell. Therefore, we can use the egg parameters as additional information in bird systematic.

Poultry products are the major source of animal protein for most people throughout the world and egg production is the major index of performance of commercial layer business and the avenue in the potential increase ofincome from the enterprise which focuses onegg yield, weight of eggs, and increasing their quality production to enhance economic performance.Microalgae is certainly an interesting solution, it aims to increase its value as an animal feed additive in new commercial applications. The experimental research was used in this study to evaluate the laying performance and egg quality of DeKalb under two feeding regimen such as feeding density andfrequency of microalgae paste Chlorella vulgaris under battery type cage system. The experiment was conducted in acompletely randomized designwith a period of 30 days with 81 Dekalb of the same age. The experimental diet used were commercial feeds,microalgae paste and feeding frequencies of 4 times, 3 times and 2 times.Egg characteristics such as total number of eggs, egg weight (g), egg length (mm), egg width (mm) and shape index (%) were computed based on the data from feeding frequency and density. The costs of feeds and price of grown Dekalb and some material used were used in the computation of return on investment. Based on the result, the effect on the external quality of eggs fed under different feeding densities and frequencies on egg production, egg width, egg weight, egg length and shape index resulted to not significantthe null hypothesis was accepted. The internal quality, the effect of different feeding densities on albumen height, albumen weight and yolk width also statistically not significant. Supplementation of microalgae Chlorella vulgaris on hen diet can be included as a dietary supplement for laying hens up to 80% of the diet to produce quality eggs.

Area And Volume

Most methods for estimating the morphometric values of water bodies use equations derived from hypsographic curves or digital terrain models (DTMs) that relate depth, volume (V), and area (A) and that model the uncertainty inherent in the complex underwater morphology. This research focuses directly on the use of topobathymetric models that include the bathymetry and topography of the surrounding area next to the water body. The projection of the water surface height (H) on each DTM pixel generates a water column with intrinsic attributes such as volume and area. The process is replicated among all cells and estimates the total area and volume of the water body. If the V or A is the input data, an algorithm that iterates height values is used to generate the new data, which is compared with the entered value that functions as a reference. If the difference between the reference value and the calculated value is less than an error threshold, the iteration stops, and the maximum and average depths are calculated. The raster and the shape that represent the body of water are created. The cross comparison of H-V-A showed that there is an error between 0.0034% and 0.000039% when any of the parameters are used as input data. Performance tests determined that pixel dimensions are directly proportional to the processing time for each iteration. The results of the implementation of this algorithm were satisfactory since, for the DTM of Bustillos Lagoon, Chihuahua, Mexico, the simulation took less than 17 seconds in at most 22 iterations.

The purpose of this study is to describe 8th-grade students’ misconceptions in solving surface area and volume of beam and cube problems and their causal factors. This is qualitative descriptive research. Based on the research, students’ misconceptions in solving surface area and volume of beam and cube problems are misconceptions on the concept of a beam, misconceptions on the concept of the cube, misconceptions on the concept of prerequisite material, misconceptions on unit comprehension, misconceptions on the understanding of meaning, and misconceptions on sign and number operations. While the causal factors of misconception are students’ assumptions about the lack of importance of concepts so students only memorize formulas, students are not able to associate one concept with other concepts, lack of understanding concepts in prerequisite material, misunderstanding the meaning of words in a problem, students have difficulty understanding pictures., misunderstanding the difference in the size of area and length.

Genetic studies were made in F2, F3 and F4 on the progeny of two common wheat crosses, Kota × Red Bobs and Kota × Garnet. Two chlamydospore collections from pure line hosts were used for inoculation in the bunt studies. The heritable nature of bunt reaction was clearly demonstrated in these crosses and evidence obtained that the degree of resistance found in Garnet must be conditioned by a single major factor. No genie hypothesis could be offered to explain the findings in regard to loose smut reaction due to a lack of agreement in infection percentages in the F3 and F4. Red kernel color in Kota and Red Bobs was found to be governed by two factor pairs. The results on the inheritance of awn characters agreed with the earlier findings of Clark and other workers with crosses of similar awned types, several factor pairs being involved. Two main factors appeared to condition the difference in strength of straw between Kota and Garnet, but the entire expression of the character can best be explained on a multiple factor basis. Correlated inheritance studies, made with the use of the correlation ratio η, indicated the presence of two linkage groups concerned with reaction to the bunt forms used. However, the linkage apparent between strength of straw and bunt susceptibility factors and between awn type and bunt resistance factors is not considered to be close enough to interfere with breeding for desirable bunt resistant varieties.

The paper discusses the relations between some physical indicators of market eggs of laying hens housed in conventional and enriched cage batteries. The measured results were evaluated by the multiple regression dependence method. They show that in the case of both the conventional as well as the enriched cages a statistically significant dependence exists between the eggshell deflection (dependent variable) and thickness, or the force needed for the eggshell destruction (independent variable). The respective P values are given in brackets (0.002 &lt; 0.05; 0.03 &lt; 0.05; 1.16 &times; 10<sup>&ndash;10 </sup>&lt; 0.05; 8.31 &times; 10<sup>&ndash;4 </sup>&lt; 0.05); in the case of the conventional cage and enriched cage also a statistically significant dependence existed (3.81 &times; 10<sup>&ndash;91 </sup>&lt; 0.05; 3.86 &times; 10<sup>&ndash;81</sup>; 1.27 &times; 10<sup>&ndash;97 </sup>&lt; 0.05; 3.46 &times; 10<sup>&ndash;57 </sup>&lt; 0.05) between the shell weight (dependent variable) and shell thickness, or egg weight (independent variable); in the conventional cage, statistical dependence also occurred between the eggshell weight and egg shape index, (1.07 &times; 10<sup>&ndash;6 </sup>&lt; 0.05), in the enriched cage this was on the verge of statistical significance (0.062 &gt; 0.05); if in the conventional cage the eggshell thickness was increased by 1 mm, the shell deflection decreased by 0.08 mm,and if the force necessary for the eggshell destruction was increased by 1 N, the shell deflection decreased by 0.0003 mm; if in the conventional cage the shell thickness was increased by 1 mm, the shell weight increasee by 15.509 g and if the egg weight was increased by 1 g, the shell weight increased by 0.061 g. Our work brings further knowledge concerning the monitored characteristics and their mutual relations.
