Three villages were randomly selected from each site for appraisals. The data were collected through discussions with the livestock keepers about the goat production systems, contribution to livelihood, role in livelihood, breeding and selection, key constraints and sale of animals. The data were analysed using Chi square test. It was found that contribution of livestock to livelihood was significantly (P 0.05) between sites and between genders with the only exception for poor and all except very poor differences (P<0.001). Modes of spending money and trends were different between sites (P<0.001). The preferred traits were number of kids, feed intake and age at maturity in Teddy goats while milk yield, body size, colour, disease resistance and taste of meat in Beetal goats. Makhi Cheeni strain of Beetal goats is preferred at Site I and Black and White spotted strain of Beetal breed is preferred at Site II. Major constraints identified were problems in production and sales, disease attacks, mortality, scarcity of drinking water, predation, theft, lack of quality breeds, feed and finance.

{"title":"EFFECTS OF MILKING FREQUENCY ON MILK PRODUCTION AND HISTOLOGICAL STRUCTURE OF UDDER IN ZARAIBI DAIRY GOATS","authors":"H. El-sayed, E. O. Saifelnasr, T. Ashmawy","doi":"10.21608/EJSGS.2013.26775","DOIUrl":"https://doi.org/10.21608/EJSGS.2013.26775","url":null,"abstract":"ABSTRACTThis work was carried out on 32 Egyptian Nubian (Zaraibi) goats to investigate both the effect of the milking frequency on milk yield and milk composition and the effect of stage of lactation on histological structure and histochemistry of the secretory mammary cells and its relationship with milk production in Zaraibi goats. Biopsies were taken surgically from the mammary gland from 3 does milked once daily (1x) and 3 does milked twice daily (2x) at the three stages of lactation, early, mid and late, for histological and histochemical studies. The histological structure showed clear differences due to milking frequency and lactation stage, being more developed at early and mid stages and twice daily milking compared to late stage of lactation and once daily milking. The number of the alveolus secretory cells per alveolus increased from the early to the mid stage of lactation by17.6% and then reduced at the late stage by 25% compared to mid stage, while no difference noticed between twice and once daily milking. Once daily milking (1x) reduced milk yield by 6%, and increased fat percentage to 4.0% compared to 3.67% in twice daily milking group (2x). Milk of once milking (1x) group contained higher percentage of total solids 11.38% than twice milking (10.93%), but milk protein and lactose did not differ between 1x and 2x milking. Lactation curve showed 32.2% increase in yield during mid stage than early stage, while late stage attained 61.3% reduction in milk yield compared to mid stage. Protein and lactose percentages did not change throughout different stages of lactation, while fat and total solids percentages showed the highest values at early stage of lactation (4.0 and 11.5%, respectively), and the lowest at mid and late stage of lactation. The total sectional areas (u/plate) of the alveoli were the smallest during late lactation (495399 u /plate) compared to that during early and mid stages of lactation (705206 and 759901u/plate, respectively).  \u0000Numerous loci of alcaline phosphatase (AP) were apparent on the outer surface of the alveolar secretory cells at the early and mid stages of lactation—reflecting high activity of this enzyme at these two stages. This was accompanied by a high level of milk secretion reaching1778.2±38.9 and 2351.4±68.4 g/head/day, respectively.In contrast, at the late stage of lactation, the size of alveoli was reduced and few alveoli showed weak AP activity. This coincided with the reduction in milk yield (910g/head/day). It could be concluded that stages of lactation influence the cell number and activity of mammary epithelial cells.","PeriodicalId":129688,"journal":{"name":"Egyptian Journal of Sheep and Goat Sciences","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124453856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two of them are “Laticauda” and “Bagnolese”, which are both considered endangered breeds and inserted in projects for genetic conservation and valorization of their products. One of these projects is the PSR, Misure 214 e2 of Campania Region. In the present study we reported the preliminary results obtained on Laticauda breed and some of their hybrids by using both chromosome banding and fluorescence in situ hybridization (FISH) mapping techniques. Peripheral blood samples from 25 animals (2 males and 23 females) were cultured for 72 hours and treated for late-incorporation of 5-Bromodeoxyuridine (BrdU) to obtain R-banded chromosome preparations which were used for both karyotype construction and FISH-mapping applications. R-banded karyotypes were performed by using the GENIKON software and following the latest international chromosome nomenclature. For FISH-mapping, both ovine and bovine BAC-clones were used, biotinilated by Nick-translation and precipitated by ethanol in presence of COT-DNA. Then they were in situ hybridized on R-banded chromosomes over night and hybridization signals were detected by using Vector chemicals. At least 30 metaphase for probe were studied by using a fluorescence microscope equipped with a digital camera and computer. Karyotype construction revealed a normal karyotype for all studied animals except female sheep which were found to be carrier of a reciprocal translocation between chromosomes 4 and 12. Concerning the FISH-mapping, examples of locus assignments are reported in both autosomes and X-chromosome.","PeriodicalId":129688,"journal":{"name":"Egyptian Journal of Sheep and Goat Sciences","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125937748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
