A total of twenty- four breeding rabbits of New Zealand White (NZW), Dutch (DUT) and their crosses (NZW x DUT) i.e. Eight (8) female rabbits (doe) for each genotype were used to determine the effects of breeds on the reproductive performance of rabbits in Rivers State, Niger Delta, Nigeria, as well as to investigate the correlation between the genotypes and the reproductive performance. The following reproductive performance were considered: Body weight before mating ( BWBM ), Body weight after mating ( BWAM ), Body weight before kindling (BWBK), Body weight after kindling (BWAK ), Litter size (LS), Litter weight (LW) and Average litter weight (ALW). Body weight was measured using weighing balance. Data generated were analyzed using Statistical Package for the Social Sciences (SPSS). The result showed significant different (p< 0.05) in BWBM and BWAM between DUT and NZW x DUT breeds of rabbits, DUT recorded the highest value of BWBM and BWAM while NZW x DUT had the least performance. However, there was no significant different (p>0.05) in reproductive performance between NZW and DUT. Furthermore, NZW recorded the highest value in BWBK, BWAK and ALW. There was no significant different (p> 0.05) among the genotypes for BWBK, L S, L W and ALW. BWAK showed a significant difference between DUT and NZW x DUT. More so, NZW x DUT recorded the highest values for L S and LW. The results also showed that genotypes effect had negative correlation with BWBW, BWAM, BWAK, BWBK and ALW with correlation values of -0.64, -0.64, -0.207, 0.385 and 0.045 respectively. The genotypes of rabbits also revealed a high correlation between BWBM and BWAM. BWAK showed a high correlation between BWAM and BWBK.

A Review of: Enger, K. B. (2009). Using citation analysis to develop core book collections in academic libraries. Library & Information Science Research, 31(2), 107-112. Objective – To test whether acquiring books written by authors of highly cited journal articles is an effective method for building a collection in the social sciences. Design – Comparison Study. Setting – Academic library at a public university in the US. Subjects – A total of 1,359 book titles, selected by traditional means (n=1,267) or based on citation analysis (n=92). Methods – The researchers identified highly-ranked authors, defined as the most frequently cited authors publishing in journals with an impact factor greater than one, with no more than six journals in any category, using 1999 ISI data. They included authors in the categories Business, Anthropology, Criminology & Penology, Education & Education Research, Political Science, Psychology, Sociology/Anthropology, and General Social Sciences. The Books in Print bibliographic tool was searched to identify monographs published by these authors, and any titles not already owned were purchased. All books in the study were available to patrons by Fall 2005. The researchers collected circulation data in Spring 2007, and used it to compare titles acquired by this method with titles selected by traditional means. Main Results – Overall, books selected by traditional methods circulated more than those selected by citation analysis, with differences significant at the .001 level. However, at the subject category level, there was no significant difference at the .05 level. Most books selected by the test method circulated one to two times. Conclusion – Citation analysis can be an effective method for building a relevant book collection, and may be especially effective for identifying works relevant to a discipline beyond local context.

This chapter addresses determinism, which has been the predominant mode of perceiving the universe in modern sciences. The basic assumption is that any event is the effect of an external cause. Generally speaking, biological determinism focuses on the biological causes of events, whereas social sciences focus on the social causes. This mode of perceiving the social universe is typically associated with positivism and, more specifically, social naturalism — or the idea that there is no significant difference between social phenomena and natural phenomena. In this logic, it is assumed that social scientists can and should discover ‘social laws’ — or universal relations of causality between a social cause and a social effect. However, determinism in the social sciences has been criticized since its very beginning. In response to these critiques, many social scientists have adopted various forms of ‘soft’ determinism. The chapter then considers social predictions and probabilism.

A series of lectures organized in part by the Society for Applied Philosophy and entitled ‘Philosophy and Practice’ is presumably aimed at displaying the practical implications of philosophical doctrines and/or applying philosophical skills to practical questions. The topic of this paper, the role of interests in science, certainly meets the first condition. For as will be argued there are a number of theses concerning the role of interests in science which have considerable implications for how one should see the scientific enterprise in general and in particular for how one assesses the claim that science ought to be accorded its priviliged position in virtue of its results and/or methods And in view of the respect and resources accorded to science what could be of greater practical interest? It remains the case, however, that my interest may seem the inverse of that of the organizers of this series. For in looking at the role of interest in science, one is examining, so to speak, the extent to which the sphere of the practical determines what goes on in science. One is exploring ways in which the non-scientific impinges on the scientific. While my primary focus will be on the physical sciences, it will be argued that there is a significant difference between them and the social sciences; a difference which renders the social sciences intrinsically liable to penetration from outside. As will be seen, some of the particular arguments for this conclusion make pressing the question: what about philosophy? The answer, it will be concluded, is that philosophy is insulated from external influences to a considerable extent. In that lies both its importance and an explanation as to why much of it has little practical application.

As farmers continue to face increasingly uncertain and often rapidly changing conditions related to markets, climate or the policy environment, people involved in agricultural research, development and extension (RD&E) are also challenged to consider how their work can contribute to supporting farmer resilience. Research from the social sciences conducted in the past decade has focussed on adaptability or adaptive capacity as a key attribute for individuals and groups to possess for managing resilience. It is, therefore, timely to ask the following: do current ways of doing and organising RD&E in the dairy sector in New Zealand and Australia contribute to supporting farm adaptability? This paper reports on results from an examination of case studies of challenges to resilience in the dairy sector in Australia and New Zealand (i.e. dairy farm conversion, climate-change adaptation, consent to farm) and the contribution of dairy RD&E in enhancing resilience of farmers, their farms and the broader industry. Drawing on concepts from resilience studies and considering an empowerment perspective, the analysis of these cases suggest that, currently, agricultural RD&E supports adaptability in general, but varies in the strength of its presence and level of activity in the areas known to enhance adaptability. This analysis is used to generate principles for dairy scientists and others in the RD&E system to consider in (1) research designs, (2) engaging different farmers in research and (3) presenting research results differently. This represents a significant shift for the science and advisory communities to move to methods that acknowledge uncertainty and facilitate learning.

The aim of this study is to investigate Social Appearance Anxiety in university students according to gender, type of faculty, grade level, body weight and height. The present study was conducted on students of Sakarya University who were between the ages of 17 and 25. 247 of the participants were female and 256 were male. The social appearance anxiety scale filled in by 503 students was evaluated. T-test, one-way analysis of variance and LSD tests were used in statistical operations. In this study, the Social appearance anxiety scale score was found to be slightly lower in women than in men in the comparison made by gender. This difference did not show a statistically significant difference according to gender (p>0.05). The social appearance anxiety score differs statistically significantly according to the type of education and training faculties (p<0.001). Social appearance anxiety changes significantly according to education level (p<0.001). It was found that the students who were satisfied with their body weight and height had lower social appearance anxiety than the students who were not satisfied. Social appearance anxiety varies according to height and body weight category (p<0.001). In conclusion, social appearance anxiety was found to be similar according to gender in this study. It differed according to the field of study of the students. The social appearance anxiety levels of the students receiving sports education are the lowest. Anxiety levels of students who receive art education are higher than those who receive sports education. The social appearance anxiety of the students who did not receive sports and art education is the highest. In order to reduce social appearance anxiety, students should be supported in sports and art education and practice.

Abstract This study was conducted to investigate the effects of different feeding strategies during gestation on the reproductive performance of sows. A total of 1121 American Landrace-Yorkshire (YL) crossbred sows and parity from 1 to 4 were assigned randomly to “North American System” feeding pattern or “Danish System” feeding pattern during gestation basing on the backfat thickness and body weight. Sows received the same diet and fed ad libitum during lactation. Results showed that over the entire gestation period, there was also no difference in average daily feed intake and total feed intake between two groups (P &gt; 0.05). “Danish System” group has significantly improved the backfat thickness at gestation 30 d (P &lt; 0.01). At 110 d of gestation, there was no difference of the backfat thickness between two groups (P &gt; 0.05). “Danish System” group had significantly increased the total number of born (P = 0.02) and born alive (P = 0.04). The number of total born (P = 0.04), stillborn (P = 0.05) and mummies (P = 0.02), had significantly different in between parities of sows. Mummies had significantly interaction effect (P = 0.01). No different was observed for the number of weaned pigs, litter weight at weaning, piglet weight, and weaning to oestrus interval between two groups. However, a significant increase of litter weight at weaning, piglet weight, was associated with increased parity of sow (P &lt; 0.01). The results of the present investigation showed that “Danish System” group could significantly increase the litter size and number born alive. Our findings point to the importance that the Danish system can be applied to North American genotypes.

Abstract Sow longevity plays an important role on the profitability of any sow operation in economically and efficiently producing pigs. An experiment was conducted to evaluate the effects of a synbiotic (Biomin® PS, BIOMIN America Inc.) containing multi-strain live probiotic strains (Enterococcus faecium, Pediococcus acidilactici, Bifidobacterium animalis, and Lactobacillus reuteri) and a prebiotic (fructo-oligosaccharaide) on sow reproductive performance. A total of 24 sows (4th and 5th parity) were divided evenly into 2 groups and fed either a control diet or a synbiotic diet during the gestation (starting on d 35 of gestation) at 1 kg/MT and lactation until weaning of piglets at 0.5 kg/MT. Daily sow feed intake was also measured during the lactation period. Sow BW was recorded pre-farrow (d 110 of gestation) and at weaning (d 21 of lactation). Piglet BW was recorded after cross-foster and on d 21 of lactation. Data were analysed using MIXED model in SAS. No significant difference was observed in sow feed intake. Relatively lower weight loss (14%) was observed during lactation in sows fed synbiotic (-24.3 kg/sow) in comparison to control fed sows (-28.4 kg/sow), although not statistically significant. A positive trend (P < 0.10) was observed with synbiotic fed sows having lower still-borns (-50%), increased number of piglets weaned per sow (+0.94 piglet/sow) and litter weight gain (+7.24 kg/litter) compared to control sows during lactation. Weaned litter weight was also increased (P < 0.05) with synbiotic feeding (78.5 kg/sow) in comparison to control (66.5 kg/sow). Overall, supplementation of the synbiotic formulation increased the sow reproductive performance by increasing weaned litter weight and number of pigs weaned while numerically lowering sow weight loss during lactation. Supplementation this synbiotic could be considered as part of sow feeding programs to improve sow reproductive efficiency.

ABSTRACTFour groups of does (16 per group) were remated either 1, 7, 14 or 21 days after parturition over a 1-year production cycle. Doe mortality rate was independent of treatment and overall was 0·27. The remating interval after parturition had no effect on conception rate, which was high on all treatments (0·86 to 0·93). The high overall conception rate resulted in more litters being born as the parturition to remating interval decreased. Expressed on a common 365-day experimental period the number of litters per doe was 8·9, 8·5, 7·8 and 6·7 (average s.e. of difference 0·33) for treatments 1, 7, 14 and 21 respectively. Litter size was not significantly affected by treatment and consequently the number of pups born per doe per year increased as remating interval decreased: 75·0, 73·4, 67·4 and 591 respectively. Pup mortality rate at birth and subsequently was high (0·42) on all treatments and the number of pups weaned per doe per year for treatments 1, 7, 14 and 21 was 48·3, 43·5, 40·0 and 33·3 respectively. Pup birth weight, 21-day litter weight and weaning (25-day) weight were all unaffected by treatment, as was doe body-weight change.
