The present study was conducted to know the morphology, morphometry, production and reproduction potentialities of Nageswari duck, an indigenous duck genetic resource of Bangladesh. Data on 58 representative adult Nageswari ducks were included for morphological study from 24 duck owners and two government organizations having Nageswari duck flocks while 468 individuals were considered for the traits of productive and reproductive performances. Information was collected by using a structured questionnaire through personal interaction, on spot recording and direct phenotypic measurements in five different regions of Bangladesh. Black plumage color with white stripe extended from neck to breast make unique features of Nageswari duck compared to other indigenous ducks. Morphometric measurements on adult live weight, body length, head diameter, bill length, neck length, shank length, wing length, massiveness and condition index in male and female were found to be 1.66±0.07 and 1.51±0.05 kg, 26.27±0.57 and 23.79±0.39 cm, 3.49±0.02 and 3.36±0.04 cm, 5.87±0.09 and 5.54±0.07 cm, 23.49±0.58 and 21.59±0.49 cm, 5.76±0.12 and 5.16±0.11 cm, 24.58±0.49 and 21.99±0.53 cm, 6.33±0.28 and 6.39±0.22, and 6.72±0.23 and 6.93±0.23 respectively. Age at first egg of Nageswari duck was found to be 168.48±3.53 days. Total number of eggs laid per year averaged 173.63±3.39 and peak production was found in 29.46±0.19 weeks. The average egg weight was estimated to be 67.32±0.82 g and characteristic bluish tinge of egg color was observed. Breed specific characteristic features and production profiles were observed in this study. The present study provided some baseline information on Nageswari duck of Bangladesh which could be useful for genetic characterization, conservation and future improvement programs in Bangladesh.Bang.

This study was conducted to investigate the morphology, morphometry and production performances of exotic goat breeds and their crossbreds available at Boalia, Shahmokhdum, Rajpara and Matihar thana under Rajshahi metropolitan city. A total of 73 animals’ information was collected from 39 exotic goat flock owners using a semi-structured questionnaire through interviewing of farmers, visual observation and on-spot measurement of the animals. Exotic goat breeds and their crosses were found predominantly higher (>93%) in Rajshahi Metropolitan areas where less than 7% Black Bengal goats were identified. In most cases, deviation of breed specific coat color due to crossing between different types of crossbreds among the populations was noted. The genotype frequencies of Beetal, Kalahari, Sirohi, Jamunapari, Anglo Nubian and their crossbreds and Black Bengal goats were found to be 50.68, 15.07, 13.70, 8.22, 8.22 and 4.11%, respectively. The average mature live weight (12 to 18 months) of those corresponding exotic genotypes in male and female respectively were found 46.88±5.66, 56.07±8.03, 32.67±8.09, 59.54±7.96 and 64.06±4.67 kg, and 21.70±2.24, 22.41±3.64, 17.37±4.05, 24.5±0.5 and 27.47±6.85 kg. Irrespective of genotypes, the mean age at puberty, lactation length, litter size, kidding interval and days open were found 167.50±3.49 days, 76.61±4.90 days, 1.71±0.10, 224.44±5.56 days and 52.64 ± 2.30 days, respectively. However, none of the aforementioned traits differed significantly (P>0.05) among the five different exotic genotypes. In conclusion, this study provides some basic information on the performances of exotic goat breeds or their crossbreds at Metropolitan areas under intensive management conditions which could be utilized for designing proper breeding plan in their conservation and simultaneous improvement.

SummaryNorth Bengal Grey (NBG) cattle are an important indigenous cattle genetic resource found mainly in the northern part of Bangladesh. The study was undertaken at Bogra Sadar, Shibgonj and Kahalu Upazila (sub-district) in the Bogra district. The physical and morphological characteristics, and the productive and reproductive performances of NBG cattle were studied. The coat colour of these animals is deep grey to white. The coat colour of the neck region in adult bulls was found to be generally ashy with a range of shades.The body is small, compact and less fleshy. Ear length and ear width were 18.0±0.17 and 11.0±0.21 cm, respectively. The head length average was 38.0±0.56 cm, the head width 16.0±0.17 cm, the foreleg length average 65.0±0.64 cm, the hind leg length 71.0±0.64 cm, the tail length average 71.0±0.67 cm, the horn length average 9.0±0.39 cm, the horn diameter 10.0±0.37 cm, the average teat length 5.0±0.18 cm, the teat diameter 6.0±0.22 cm, the distance betweenthe front teats 7.0±0.13 cm and the distance between the rear teats 7.0±0.13 cm. Body length, height at wither and heart girth in adult cows were 105.0il.20, 94.0+1.12 and 127.0±1.52 cm, respectively.The recorded highest peak milk production per day was 3.5±0.18 kg, lactation length was 219±6.1 days, and the dry period was 180±6.8 days. The average birth weight of calves was 18.4±0.52 kg and mature live weight of cows 241.0±4.0 kg. The age at first heat was 869±29.6 days, age at first calving 1191±19.7 days, gestation length 281±1.3 days, calving interval 442±7.4 days, postpartum heat period 110±4.2 days and the number of services per conception 1.4±0.6. About 54% of total cattle population was NBG cattle in the surveyed area of Bangladesh. The results indicated that the productive and reproductive performance of NBG cattle was better than other non-descript indigenous cattle of Bangladesh. The study further revealed an obvious need for more in-depth and objective information on wider samples of this type of indigenous cattle in order to assess the future need for conservation and improvement programs to be undertaken.

SummaryThis study was conducted to characterize the morphological peculiarities and performance characteristics of Mursi cattle in its production environment managed by Bodi and Mursi pastoral communities in Southern Ethiopia. A structured questionnaire survey, group discussion, cattle morphological measurements and morphological descriptions were used to collect data. One hundred and two household heads were selected to administer the questionnaire and 201 adult cattle were selected for morphological description and body measurements. The Mursi cattle population was found to have variable coat colour type (85.9 percent) and coat colour pattern (51.3 percent). Body length, chest girth, withers height, rump width and rump length of Mursi cattle were 122.1 ± 0.9, 144.5 ± 0.9, 113 ± 0.1.1, 36.9 ± 0.3 and 20.4 ± 0.3 cm, respectively. Morphological measurements of most linear traits show no difference in the two locations but all measurements vary (P< 0.001) between males and females. Estimated age at first calving was 4.6 years and was significantly (P< 0.0001) higher in the Mursi area, while the calving interval (14.5 months) and cow reproductive life (14.2 years) were the same in both locations. Average daily milk yield (2.1 litres) and lactation length (7.8 months) of Mursi cattle in the two locations were similar. Cattle production was constrained by high disease prevalence, seasonal feed availability, and water shortage, with frequent drought. Trypanosomosis, black leg, anthrax and skin diseases are major cattle diseases reported in the two study areas. Because of its peculiar morphological characteristics, including large body frame, higher production performance, and survivability in the harsh environment, the Mursi cattle can be used as an alternative genetic resource for production improvement programs.

Estimates were made of the increase in live and dry weights and in the content of ash, organic matter, carbohydrate (as glucose), and nitrogen when juveniles of the clam Saxidomus giganteus were fed for 21 days at various concentrations of Tetraselmis chui, Isochrysis galbana, and Phaeodactylum tricornutum. The condition index (organic weight as a percent of total dry weight) increased in all the experimental conditions with a mixture of I. galbana and T. chui, yielding a significantly higher index than either species on its own. The relative gain in glucose was greater than the increase in live weight or in nitrogen. The increase in live weight was such that the nigrogen content was approximately constant at 6–7 μgN/mg live weight irrespective of the feeding conditions. The N:glucose ratio decreased with increasing concentrations of I. galbana and P. tricornutum, and at the higher concentrations, where the maximum growth rate of clams occurred, the ratios were lower than in any of the clams fed on T. chui.

Background and Objectives: This study was aimed to provide baseline information on infant feeding knowledge, practices and hindering factors for proper feedings.Material and Methods: Among the 185 women with less than one year child coming on immunization clinic of health post of Chisapani Village Development Committee, infant feeding knowledge, practices were assessed by interviewing with semi structured questionnaire and focus group discussion.Results: Male children were more exclusively breastfed (33%) than female (27%) and exclusive breast feeding was lower in fifth and sixth month of age. All of them were aware that the baby should be fed only breast milk for 6 months, but the exclusive breastfeeding practice was found only in a very few mothers. Most of them had fed solid food after 3 months.Conclusion: Knowledge and practices on infant feeding do not go along despite the adequacy of knowledge due to the hindering factors like poverty, working mother, lack of support from family members and lack of support from the government infant. The gap between knowledge and practice can be lessened via informative activities on lactation management, endorsing policies and rights for mothers-infants relationship.

Jain, S., Porter, L. D., Kumar, A., Mir, R. R., Eigenbrode, S. D. and McPhee, K. E. 2014. Molecular and phenotypic characterization of variation related to pea enation mosaic virus resistance in lentil (Lens culinaris Medik.). Can. J. Plant Sci. 94: 1333–1344. Identification of genetically diverse lentil germplasm with resistance to pea enation mosaic virus (PEMV) through the combined approach of molecular marker analysis and phenotyping could prove useful in breeding programs. A total of 44 lentil (Lens culinaris Medik.) accessions, were screened for resistance to PEMV. Two accessions (PI 431663 and PI 432028) were identified with resistance to PEMV in field tests while several accessions were found resistant in greenhouse screenings. Thirty-six polymorphic simple sequence repeat (SSR) markers which produced 43 loci with 2 to 12 alleles per locus were used for genetic diversity analysis. The polymorphic information content (PIC) values for these markers ranged from 0.22–0.85 with a mean of 0.55 per marker. Using allelic data of 36 SSR primer pairs, dissimilarity ranging from 0.12 to 0.74 was calculated. Cluster analysis performed using the unweighted pair group method with arithmetic mean (UPGMA) determined that most of PEMV-resistant accessions were grouped in one cluster along with other accessions from Iran, Chile, Ethiopia, India, Pakistan, Turkey, Afghanistan and Lebanon. All the adapted cultivars originating from North and South America were grouped in another cluster along with some European accessions. The 44 accessions were classified into 4 subpopulations using Structure 2.2 software complimenting the results of UPGMA analysis and indicated the effect of geographical origin on the grouping of accessions. The results of this study can be used to select genetically diverse PEMV-resistant accessions for lentil improvement programs.

Smith-Lemli-Opitz Syndrome (SLOS) is a developmental disorder (OMIM #270400) caused by autosomal recessive mutations in the Dhcr7 gene, which encodes the enzyme 3β-hydroxysterol-∆7 reductase. SLOS patients present clinically with dysmorphology and neurological, behavioral and cognitive defects, with characteristically elevated levels of 7-dehydrocholesterol (7-DHC) in all bodily tissues and fluids. Previous mouse models of SLOS have been hampered by postnatal lethality when Dhcr7 is knocked out globally, while a hypomorphic mouse model showed improvement in the biochemical phenotype with ageing, and did not manifest most other characteristic features of SLOS. We report the generation of a conditional knockout of Dhcr7 (Dhcr7flx/flx), validated by generating a mouse with a liver-specific deletion (Dhcr7L-KO). Phenotypic characterization of liver-specific knockout mice revealed no significant changes in viability, fertility, growth curves, liver architecture, hepatic triglyceride secretion, or parameters of systemic glucose homeostasis. Furthermore, qPCR and RNA-Seq analyses of livers revealed no perturbations in pathways responsible for cholesterol synthesis, either in male or female Dhcr7L-KO mice, suggesting hepatic disruption of post-squalene cholesterol synthesis leads to minimal impact on sterol metabolism in the liver. This validated conditional Dhcr7 knockout model may now allow us to systematically explore the pathophysiology of SLOS, by allowing for temporal, cell and tissue-specific loss of DHCR7.

The paper is based on the revealed domestic publications and analysis of vast publications in the foreign professional periodicals. Internet-based resources, e. g. www-sites of diverse organizations were analyzed, and the data on efficient Russian corporate libraries was identified. The national library studies exclude corporate libraries from the traditional official library typology. The national classification system (Library Bibliographic Classification, LBC) as well, does not envisage typology for the corporate libraries. The author does not possess statistical data. Some experts relate the concept to “corporations”, others see the corporate libraries as former “technical” (sectoral, industrial) libraries. However, the analysis findings demonstrate that this term can be primarily related to the concept of “corporate culture”. The corporate libraries make part of corporations, financial and trade companies, banks, foundations, joint-stock companies, etc. The prerequisites of extensive uprise of these libraries in Russia emerged in 1990s. The few publications on the topic are discussed along with the information available from Internet resources. The author concludes that the corporate libraries belong to special libraries, and within the latter group, the corporate libraries should be separated. Both state-funded and non-government organizations have got the libraries within their structure. The author attempts to formulate the definition for the new type of libraries, examines their functions and characteristic features, staff and users. The examples of the place of these libraries within the organizational structure are provided.

Для достижения указанной цели на комплексе ООО фирма Хаммер сформировали две группы бычков калмыцкой и симментальской породы по 30 голов в каждой. Подопытных животных откармливали по принятой технологии, в течение полного производственного цикла длительностью 392 дня, который делился на 2 периода. Затем всех подопытных бычков поставили на среднеинтенсивное выращивание продолжительностью 150 дней. Далее следовал интенсивный заключительный откорм продолжительностью 88 дней. Общая продолжительность технологического цикла составила 21 месяц (630 дней). Контрольный убой пяти голов из каждой опытной группы проводили в возрасте 13, 18 и 21 месяца по достижению живой массы 330380 450560 и 490640 кг соответственно. Для изучения мясной продуктивности и морфологического состава туш пользовались общепринятыми зоотехническими методами исследования. Результаты исследований показали, что молодняк симментальской породы обладает хорошим потенциалом мясной продуктивности, что позволяет в условиях комплекса эффективно откармливать бычков до живой массы 643 кг в возрасте 21 месяц и получать высококачественные туши массой 328,1 кг. Бычков калмыцкой породы в условиях промышленного комплекса эффективнее откармливать до 18тимесячного возраста. Характерными признаками мясной продуктивности симментальских бычков являются достаточно высокая убойная масса и выход мяса.The purpose of the study the choice of the most affordable and costeffective technological options for different production cycles, a comparative assessment of meat productivity and efficiency of growing and fattening calves and Simmental rocks at different cycles (aged 392 542 and 630 days) production in the industrial complex.

Government and non-government organizations (NGOs) interventions to local farmers in the recent past had not yielded the desired result because these interventions were not tailored towards the needs of farmers. However, most information on the needs of target farmers have been very scanty thus, the need to use a bottom top approach to assess farmers' needs in Ibarapa East, Oyo state. A three-stage sampling technique was used to purposively select about 225 respondents. Parameters measured were household characteristics, farm sizes, farm labor availability, seasonal pattern and need to be assessed using a participatory rural appraisal approach comprising of focus group discussion (FGD) and structured questionnaire. Data were analyzed descriptively and the need assessed using the pair-wise ranking and simple matrix. Of challenges listed in FDG among crop-livestock farmers, only five (5) were prioritized as follows; wastage of agricultural products (Pb1), bad road network (Pb2), high cost of agricultural inputs (Pb3), lack of potable water (Pb4) and animal invasion (Pb5). The pairwise comparison of the percentage of Pb1 versus (vs.) Pb2 was 80/20%, Pb1 vs. Pb3 was 90/10%, Pb1 vs. Pb4 was 70/30%, Pb1 vs. Pb5 was 20/80%, Pb2 vs. Pb3 was 70/30%, Pb2 vs Pb4 was 30/70%, Pb2 vs. Pb5 was 10/90%, Pb3 vs. Pb4 was 20/80%, Pb3 vs. Pb5 was 10/90%, vs. Pb4 vs Pb5 was 30/70%, respectively. There were proffered solutions to the problem(s) itemized by the FGD. The animal invasion was ranked highest as farmers' need assessed for possible intervention in Ibarapa East. Governments and NGO funds should be addressing animal invasion for desirable project impact assessment.     Les interventions des gouvernements et des organisations non gouvernementales (ONG) auprès des agriculteurs locaux dans un passé récent n'avaient pas donné le résultat souhaité car ces interventions n'étaient pas adaptées aux besoins des agriculteurs. Cependant, la plupart des informations sur les besoins des agriculteurs cibles ont été très rares, ce qui nécessite d'utiliser une approche ascendante pour évaluer les besoins des agriculteurs de l'est d'Ibarapa, dans l'État d'Oyo. Une technique d'échantillonnage en trois étapes a été utilisée pour sélectionner environ 225 répondants. Les paramètres mesurés étaient les caractéristiques des ménages, la taille des exploitations, la disponibilité de la main-d'oeuvre agricole, le profil saisonnier. Ils doivent être évalués à l'aide d'une approche d'évaluation rurale participative comprenant des discussions de groupe et un questionnaire structuré. Les données ont été analysées de manière descriptive et le besoin évalué en utilisant le classement par paires et une matrice simple. Parmi les défis énumérés dans le 'FDG' chez les agriculteurs et les éleveurs, seuls cinq (5) ont été classés comme suit; gaspillage des produits agricoles (le 'Pb' 1), mauvais réseau routier (le 'Pb' 2), coût élevé des intrants agricoles (le 'Pb' 3), manque d'eau potable (le 'Pb' 4) et invasion animale (le 'Pb' 5). La comparaison par paire du pourcentage de 'Pb' 1 versus (vs) 'Pb' 2 était de 80/20%, Pb1 vs Pb3 était de 90/10%, Pb1 vs Pb4 était de 70/30%, Pb1 vs Pb5 était de 20/80% Pb2 vs Pb3 était de 70/30%, le 'Pb' 2 vs le 'Pb4' était de 30/70%, le 'Pb' 2 vs le 'Pb' 5 était de 10/90%, le 'Pb' 3 vs. le 'Pb' 4 était de 20/80%, le 'Pb' 3 vs. le 'Pb' 5 etaient 10/90%,vs le 'Pb' 4 vs le 'Pb'5 était respectivement de 30/70%. Des solutions ont été proposées au (x) problème (s) détaillé (s) par le FGD. L'invasion animale a été classée au premier rang des besoins des agriculteurs évalués pour une éventuelle intervention à l'Estd'Ibarapa. Les gouvernements et les fonds d'ONG devraient s'attaquer à l'invasion animale pour une évaluation de l'impact souhaitable du projet.
