This study aims to determine the correlation between hatching egg weight with egg weight loss and DOC weight of Bangkok male crossbreed chickens with Pelung broodstock. This research uses a unit of automatic digital hatching machines (temperature regulation and automatic turning). The research material is Bangkok rooster chicken, amounting to two tails and four Pelung broilers. The chicken is crossed, and then the eggs are collected to be hatched eggs. This study uses digital camera tools, digital scales, and calculators. The coded eggs are hatched for 21 days. The parameters measured in this study were: Hatching egg weight (grams), egg weight of day 18th hatching, egg weight loss (%) / egg shrinkage, DOC weight, the correlation value between the weight of hatching eggs with egg weight loss, the correlation value between the weight of hatching eggs with the weight of DOC. Data analysis using correlation. The results obtained were the average hatching egg weight of 45.91 ± 3.75 grams, the average of hatching eggs on the 18th day 41.13 ± 3.43 grams, egg weight loss 10.40 ± 0.56%, weight DOC 35.36 ± 3.33 grams, correlation of hatching egg weight to DOC0.98 weight, hatching egg correlation with egg weight loss -0.25. Based on the results of the study,  it can be concluded that the characteristics of Bangkok crossbreed hatching eggs with Pelung brooders are in the normal range.  The correlation of hatching egg weight with very high DOC weight and positively correlated, correlation of hatching egg weight with low egg weight loss and negatively correlated.

Abstract. The relationships between age of hens, number of laid eggs, egg weight on one hand and fertility and hatchability on the other were analysed during two periods of individual pedigree hatching. Altogether 1 369 hens originated from 9 selected initial laying lines of Bar Plymouth Rock (BPR) (3 lines), Rhode Island Red (RIR) (4 lines), Rhode Island White (RIW), and Sussex Light (SUL) breeds. A total number of 23 473 eggs from hens of all 9 aforementioned lines were set after being artificially inseminated. The total average hatchability of set eggs was 73.2 % and the average percentage of unfertilised eggs was 9.3 %. Positive correlations (rp =0.22 to rp =0.72; P<0.01) were found between the total number of eggs laid till the 240th day of age and the number of eggs produced at the beginning of the laying period in the all studied lines. There were negative correlations (rp =−0.03 to rp =−0.16; P<0.01) between the total number of eggs laid till the 240th day of age and the average egg weight (on the 222nd day of age). Zero to positive correlations existed between the total number of eggs laid till the 240th day of age on one hand and the number of hatching eggs, number of hatched chicks/hen and hatchability; the calculated values ranged from rp =−0.02 to rp =0.30 (P<0.01), from rp = −0.08 to rp =0.36 (P<0.01), and from rp =−0.09 to rp =0.30 (P<0.01), respectively. Correlations between the egg weight and number of hatched chicks/hen were negative to zero and their values ranged from rp =−0.19 (P<0.01) to rp =0.02. Correlations between the egg weight and hatchability were always negative (rp =−0.15; P<0.05 to rp =−0.04). Regarding the fact that there is a concurrent selection for an increased egg weight it can be said that this preference of smaller eggs is really counter-productive. A positive relationship between the number of hatching eggs/hen and the hatchability (rp =−0.02 to rp =0.39; P<0.01) was influenced by calculated negative correlations existing between the weight of eggs and the hatchability as well as between the weight of eggs and the number of laid eggs. As far as the hatchability is concerned, it can be concluded that in the aforementioned laying lines those hens are preferred, which produce more eggs of smaller size and that this fact obviously influences also the efficiency of selection for a greater weight of produced eggs.

The aim of study was to examine the values of the incubation parameters(weight loss, fertilization, hatchability of placed and fertilized eggs, total, early,middle and late embryonic mortality) of eggs of different weights in brolier hybridCobb 500. In total, 600 eggs were divided into four equal groups (n = 150 each)according to their weight: 57.5-62.5 g (S); 62.6-67.5 g (M); 67.6-72.5 g (L) and 72.6-77.50 g (XL). Values of incubation parameters were determined and statisticallyprocessed by standard methods. The weight of eggs significantly influenced the lossof egg weight during incubation (p<0.05), with this loss being higher in smaller eggs(group S 11.10% and group M 11.40%) compared to larger eggs (group L 10.42%and group XL 10.31%). Hatchability of all eggs in groups S, M, L and XL was 76.0;75.3; 78.7 and 66.0%, respectively, and for fertilized it was 82.0; 81.3; 82.5 and71.7%, respectively, with no significant difference (p>0.05). The weight of eggs didnot significantly affected the difference in embryo mortality values, although in theXL egg group a higher value of total, early and late mortality was found, comparedto other groups. The results of this study indicate lower hatchability and highermortality of embryos in eggs of extremely large weight, compared to other groups,which indicates that special attention should be given to the selection of hatchingeggs in terms of their weight.

Four thousand two hundred hatching eggs were obtained from Bandarah chicken to evaluate the effect of chemical and natural egg disinfectants and fumigation on egg weight loss, embryonic mortality, hatchability, hatch time, chick weight and chick weight loss. Three incubation trials were done; each one contained 1400 hatched eggs and divided into fourteen treatments (100 eggs per each). First treatment (T1) was used as control without any treatment, eggs of second treatment (T2) were dipped in water and third treatment in alcohol, whereas T4, T5, T6, T7 treated egg groups were dipped in chemical disinfectant (sodium chloride, betadine, hydrogen peroxide, virkon S). Egg of T9, T10, T11, T12, T13 and T14 groups were dipped in natural disinfectants (oregano, cumin 02 and 04 % and oregano+ cumin01 and 02), respectively. The thickest eggshell (031mm) was recorded for betadine group in infertile eggs compared with those for formaldehyde fumigation and oregano+cumin 01% oregano+cumin 01% group (035mm) compared with all other treatment groups. Formaldehyde fumigation recorded the worst and highest significant percentage of embryonic mortality (1795%). Highest significant percentages for hatchability of fertile egg were recorded in egg groups with oregano 02 and 04% (9687 and 9576%), cumin 02 and 04 % (9551and 9715%) and oregano+cumin01 and 02% (9619 and 9615%), respectively.

Thrombotic thrombocytopenic purpura (TTP) is a rare but serious illness of unknown etiology. Treatment by plasmapheresis has been reported to be effective but the mechanism for benefit is unknown. We have investigated the effect of plasmapheresis in 2 patients with TTP by quantitating platelet associated IgG (PAIgG) levels prior to and following plasmapheresis. Both patients had very high levels of PAIgG at presentation (90 and A8 fg IgG/platelet respectively, normal 0-5). in both, the PAIgG levels progressively fell to within the normal range and the platelet count rose following plasmapheresis. One patient remained in remission with normal platelet counts and PAIgG levels. The other relapsed after plasmapheresis and the PAIgG level rose prior to the fall in platelet count. Plasmapheresis was repeated and resulted in normalization of both the platelet count and PAIgG level. It is suggested that plasmapheresis removes antiplatelet antibody or immune complexes which may be of etiological importance in this illness.
