Abstract Litter sizes in commercial pig production have increased substantially over recent years; however, farrowing pen sizes have generally not changed over the same time period. The objective of this study was to evaluate the effect of farrowing pen size on piglet pre-weaning growth and mortality. Differences in pen size were created by varying the width of pens of the same length, increasing the creep area available to the piglets. The study used a total of 1,786 litters in a randomized complete block design to compare two Farrowing Pen Size treatments (FPS): Standard (pen width 1.52 m) and Increased (pen width 1.68 m). Litter sizes were equalized across treatments (12.9 ± 1.95 piglets) at 24 h after birth using cross-fostering. Litter weights were collected at birth and weaning (21.3 ± 2.08 d); pre-weaning mortality was recorded. The experimental unit was the litter; models included FPS and replicate. Farrowing Pen Size had no effect (P > 0.05) on litter size at birth (12.8 and 13.0 for the Standard and Increased FPS, respectively), after cross-fostering (12.9 for both treatments), or at weaning (11.2 and 11.3, respectively). There was no effect (P > 0.05) of FPS on total litter or average piglet weight at birth, after cross-fostering, and at weaning. These results suggest no benefit in piglet performance from increasing the width of farrowing pens. As litter sizes continue to increase in commercial production, further research is warranted to re-evaluate the impact of farrowing pen size on pre-weaning mortality.

The Impact

This article examines the impact of medical technologies on the concept of justice and the human body. Traditionally, theories of justice require individuals to transfer material resources to other individuals who are needier or worse off. But three technologies, organ transplantation, genetic engineering, and artificial wombs, have changed our obligations to one another. It appears that justice now requires us to subject our body to sometimes invasive procedures should others need our bodily resources, particular genes, or nutrients which we no longer want to provide through our body itself.

Ordinary Citizens

Genetic engineering is a social invention as much as a biological one. Ordinary citizens interested in the well-being of life on the planet should therefore be involved in the ethical debates concerning the future of nonhuman animals. The creations of genetic engineers ought to be evaluated on a case-by-case basis by what the American philosopher R. G. Frey calls “a jury of concerned individuals.” Frey is an advocate for putting animals in perspective, which means that animals matter, but not as much as humans. He therefore supports the prevailing moral orthodoxy, which currently in the West means that animals can be eaten, dissected, hunted, and exhibited, provided that these things are done humanely and that the benefits to humans outweigh the harms to the animals. The “concerned individual,” he suggests, would have no objection to humans killing animals as long as the animals do not suffer. In the present paper, my aim is to raise some of the ethical, welfare, and social issues from an animal-protectionist perspective which ordinary citizens would need to consider if they were ever asked to vote on the benefits or otherwise of the impact of genetic engineering on animal welfare.

The Impact

The research work was carried out to investigate the efficacy of different mother culture media viz., rice straw (T-1), rice straw and rice bran (T-2), rice husk (T-3), rice grain (T-4), maize grain (T-5), and rice straw and wheat bran (T-6) and the impact of age of mother culture and substrate sterilization techniques viz., sun dried for 8 hrs covering with transparent polythene (A-1), black polythene (A-2), blue polythene (A-3) sheet, autoclave for two hrs at 121°C (A-4), and hot water for one hr (A-5) for the commercial cultivation of Volvariella volvacea (Bull.) Singer. The maximum mycelium run rate and minimum days required for completing the mother culture were recorded in T-4. The lowest days required for primordial initiation (DRFPI) was 6 in T-1 and T-2, whereas highest DRFPI was recorded in T-3. The maximum (13.33) days required for first harvest (DRFFH) and lowest (109) number of effective fruiting bodies (NEFB) were recorded in T-3. The minimum (10.67 days) DRFFH was found in T-2 and maximum (239.30) NEFB was recorded in T-1. The lowest length and diameter (LFB and DFB) were recorded in T-5 (3.03 cm) and T-1 (1.66 cm), while highest LFB and DFB were observed in T-3 (3.20 and 2.39 cm). Maximum biological yield and efficiency were observed in rice straw and wheat bran materials. The highest NEFB, DFB, biological yield and efficiency were recorded in 30 days old of mother culture. The results revealed that combined rice straw and wheat bran were the excellent mother culture medium and 30 days old was the best age for the commercial production of paddy straw mushroom. Considering the experimental results on the sterilization techniques it may be suggested that hot water sterilization of rice straw substrate was the best sterilization technique for the commercial production and yield improvement of V. volvacea.

Farrowing Rate

The most common manifestations of seasonal infertility are delayed puberty, prolonged weaning to oestrus intervals and a reduced farrowing rate brought about by increased returns to oestrus, including a proportionally higher incidence of irregular returns to oestrus. Over the past 40 years, there has been considerable investment in Australian pig research that has generated extensive knowledge about the physiological mechanisms behind seasonal infertility. While some of the physiological mechanisms allowing the expression of seasonal infertility still remain unclear, a number of possible intervention strategies have been developed and investigated to ameliorate the effects of seasonal infertility in commercial production. For commercial pork producers, there is considerable information available that is based on both research and practical experience, which the farmers can use to identify strategies to minimise the impact of seasonal infertility on the farm. The industry still provides some support to research and development efforts to address seasonal infertility, although, in the future, it may be more targeted to identifying interventions to ameliorate the impact of seasonal infertility in affected herds, rather than undertaking intensive studies into the possible mechanisms and reasons behind this very complex syndrome.

The world oil market is changing rapidly, there rises a new global center of world oil production – North America, which production opportunities are estimated by experts as outperforming those of Middle East. This is made possible thanks to inception of commercial oil production from oil shale in North America. The article deals with the problems and prospects of the development of shale oil in the U.S. and the impact of the growth of its production on the configuration of the world oil market.

Objective: To describe Fusarium oxysporum f. sp. niveum (Fon) as the causal agent of vascular withering in the watermelon crop (Citrullus lanatus (Thunb.) Matsum and Nakai). Design/Methodology/Approach: A review of scientific literature (scientific books, notes and articles) was carried out about Fon as the causal agent of vascular withering in the watermelon crop; biology, symptoms, disease cycle, isolation and management alternatives. Results: Withering from Fusarium in watermelon is the main fungal disease of this crop worldwide. Necrosis of the vascular tissue and withering of the plant are the most characteristic symptoms of the disease. There are four races of this fungus (Fon race 0, 1, 2 and 3); the commercial varieties of watermelons have different degrees of resistance to these races. Practices such as the correct diagnosis, use of grafts, solarization, fungicides, biological products and genetic resistance can significantly reduce the impact of the disease on the production. Findings/Conclusions: In Mexico, knowledge about vascular withering of watermelon is scarce despite this disease being one of the factors that limits commercial production. The greatest knowledge about the symptoms, the fungus’s biology, presence and distribution of races, diagnosis and alternatives of Fon management, will allow integrating appropriate management practices that favor the commercial production of the crop.
