AGE-RELATED CHANGES IN THE PERCENTAGE CONTENT OF CARCASS PARTS IN GEESE
Daria MURAWSKA,Roman BOCHNO
Journal of Central European Agriculture , 2008,
Abstract: The experimental materials consisted of Koluda White geese, 128 males and 128 females, raised for 12 weeks and fed standard diets ad libitum. Starting from the second week, 28 birds (sex ratio 1:1) were slaughtered at 14-day intervals. Chilled carcasses were dissected into neck, wings, legs, breast and back. Over the experimental period, the body weights of males and females increased on average from 158 g and 112 g on the first day to 5483 g and 5045 g at 12 weeks, respectively. Sexual dimorphism was observed from 4 weeks of age, both in body weight and carcass weight. At the initial growth stage, the percentage content of wings in the carcass increased rapidly (from 5.03% at 2 weeks to 17.44% at 6 weeks), while the proportion of legs decreased (from 40.5% at 2 weeks to 25.55% at 8 weeks). Breast percentage showed a growing tendency (from 19.38% at 2 weeks to 32.70% at 12 weeks), whereas neck and back – a falling one (from 10.13 and 24.96% to 7.73 and 19.61%, respectively).

Food and Nutrition Sciences (FNS) , 2013, DOI: 10.4236/fns.2013.49123
Abstract:

Cooling, transportation and sale processes of spiced geese were studied, eight spiced geese meat samples with different sampling time, Airborne microorganism samples of three different workplaces and five different environmental contact substance samples were test, measures of special mediums, biochemical identification and DNA sequencing were carried out, then Escherichia coli, Yeast, Mildew, Lactic acid bacteria, Staphylococcus aureus and Janthinobacterium were detected. For spiced geese meat samples, microorganisms were significant (p < 0.05) increased with the prolong of sampling time. Lactic acid bacteria, Staphylococcus aureus and Janthinobacterium were detected in each processing operation and the total aerobic counts of each sample was increased or significant (p < 0.05) increased with the prolong of sampling time; Escherichia coli, Yeast and Mildew were detected on samples entered into the retail outlet mainly and the total aerobic counts of each sample was increased or significant (p < 0.05) increased also. In the household workshop, Mildew and Janthinobacterium were the superior microorganisms. In the transport vehicle, Staphylococcus aureus and Janthinobacterium were the superior microorganisms; Staphylococcus aureus was the superior microorganism in the retail outlet. For environmental contact substances, Cooling platform, pallet, chopping block were the most serious contaminated environmental contact substances and the total bacteria counts were significant (p < 0.05) more than stainless steel barrel and chopper; Janthinobacterium was the superior microorganism on pallet, stainless steel barrel and chopper; Lactic acid bacteria was the superior microorganism on chopping block and stainless steel barrel; Staphylococcus aureus was the superior microorganism on cooling platform. Findings indicate that Escherichia coli, Yeast, Mildew, Lactic acid bacteria, Staphylococcus aureus, Janthinobacterium were the main microorganisms; Household workshop and the retail outlet were the main place microorganisms contaminated; Pallet, stainless steel barrel and chopper were the main environmental contact substances.

Journal of Central European Agriculture , 2006,
Abstract: A review of the methods for balanced experiments for establishing of the metabolizable energy and the amino acids digestibility for waterfowl has been made. Systemizing the former experience in this fi eld, the author submits some innovations, regarding to the adaptation of the methods for experiments with geese. The results for metabolizable energy and true digestibility coeffi cients of some basic for the feeding of geese forages (established using the adapted methods) are given. A using of specifi ed for the different birds data for the nutritive values of the forages has been recommended. The offered innovations could be used for further efforts for establishing of standardizing methods for balanced experiments with waterfowl.
Impact of Avian Influenza in Some States of Nigeria
L. Saidu,A.M. Wakawa,P.A. Abdu,D.F. Adene
International Journal of Poultry Science , 2008,
Abstract: Cases of Avian Influenza (AI) outbreaks reported and confirmed were extracted from the records of control committees on AI in Kano and Katsina States, Veterinary Teaching Hospital of Ahmadu Bello University, Zaria, Pan-African Control of Epizootics (PACE) project office at Kaduna. Information on Al outbreaks in Jigawa State were obtained through a questionnaire. A total of 480,378 birds were lost in 34 outbreaks in the four states under study between the period of January and March 2006. Chickens accounted for more than 99% of all the birds affected followed by guinea fowls and turkeys. More than 60% of the birds affected were adults. The concentrations of poultry farms in Kano metropolis particularly along Gwarzo road where the epidemic was first noticed might have been responsible for the fast spread of the disease within Kano metropolis. It is a common practice to find geese, muscovey ducks and turkeys in one farm in the study area. This practice makes the chickens and turkeys more prone to the disease. From the tract of outbreaks It is possible that the disease spread from Jigawa State to Kano state and from Kano State to other States in the study area and other parts of the country through trade in live birds and poultry by products. For proper diagnosis and control of AI in Nigeria, poultry farmers should be educated on the necessity for prompt disease reporting to veterinarians and appropriate authorities.

Kirill Sharshov, V. Marchenko, Fang Yang, A. Alekseev, Jian Cao, Zhuo Li, A. Shestopalov, Lai-Xing Li
Advances in Infectious Diseases (AID) , 2014, DOI: 10.4236/aid.2014.41003
Abstract:

The aim of study was to detect H5N1 virus in wild geese in Qinghai Province in 2012. The work was provided according to WHO and OIE guidelines. In 2012, we collected 532 samples from wild geese of two species: Bar-headed Goose (Anser indicus) and Graylag Goose (Anser anser). We analyzed samples by chicken embryo inoculation and PCR. No avian influenza viruses were isolated. History of HPAI H5N1 shows obvious importance of Central Asian region in its spreading. The outbreaks of the H5N1 Highly Pathogenic Avian Influenza (HPAI H5N1) were reported in wild birds at the Qinghai Lake since 2005. This area seems to be key point for H5N1 avian influenza surveillance in wild birds. We did not find viruses although H5N1 cases in poultry were reported from 5 provinces of China in 2012. Annual surveillance is required for early AIV detection in this region.

Lack of detection of host associated differences in Newcastle disease viruses of genotype VIId isolated from chickens and geese
Wang Yuyang,Duan Zhiqiang,Hu Shunlin,Kai Yan
Virology Journal , 2012, DOI: 10.1186/1743-422x-9-197
Abstract: Background The goose is usually considered to be resistant even to strains of Newcastle disease virus (NDV) that are markedly virulent for chickens. However, ND outbreaks have been frequently reported in goose flocks in China since the late 1990s with the concurrent emergence of genotype VIId NDV in chickens. Although the NDVs isolated from both chickens and geese in the past 15 years have been predominantly VIId viruses, published data comparing goose- and chicken-originated ND viruses are scarce and controversial. Results In this paper, we compared genotype VIId NDVs originated from geese and chickens genetically and pathologically. Ten entire genomic sequences and 329 complete coding sequences of individual genes from genotype VIId NDVs of both goose- and chicken-origin were analyzed. We then randomly selected two goose-originated and two chicken-originated VIId NDVs and compared their pathobiology in both geese and chickens in vivo and in vitro with genotype IV virus Herts/33 as a reference. The results showed that all the VIId NDVs either from geese or from chickens shared high sequence homology and characteristic amino acid substitutions and clustered together in phylogenetic trees. In addition, geese and chickens infected by goose or chicken VIId viruses manifested very similar pathological features distinct from those of birds infected with Herts/33. Conclusions There is no genetic or phenotypic difference between genotype VIId NDVs originated from geese and chickens. Therefore, no species-preference exists for either goose or chicken viruses and more attention should be paid to the trans-species transmission of VIId NDVs between geese and chickens for the control and eradication of ND.
Geese PSO Optimization in Geometric Constraint Solving
Cao Chun- Hong,Wang Li- Min,Han Chun-Yan,Zhao Da-Zhe
Information Technology Journal , 2012,
Abstract: Geometric constraint problem is equivalent to the problem of solving a set of nonlinear equations substantially. The constraint problem can be transformed to an optimization n problem. We can solve the problem with GeesePSO optimization. In this paper, an improved algorithm is proposed using the characteristics of the flight of geese for reference. The improved algorithm has superiority over PSO; for one thing, it keeps the population various by ordering all the particles and making each particle fly following its anterior particle; for another thing, it strengthens cooperation and competition between particles by making each particle share more useful information of the other particles. The experiment shows that it can improve the geometric constraint solving efficiency and possess better convergence property than the compared algorithms.
