Experimental design, power and sample size for Animal Reproduction experiments.Reproduction fertility and development, 2008Co-Authors: Phillip L. Chapman, George E. SeidelAbstract:
The present paper concerns statistical issues in the design of Animal Reproduction experiments, with emphasis on the problems of sample size determination and power calculations. We include examples and non-technical discussions aimed at helping researchers avoid serious errors that may invalidate or seriously impair the validity of conclusions from experiments. Screen shots from interactive power calculation programs and basic SAS power calculation programs are presented to aid in understanding statistical power and computing power in some common experimental situations. Practical issues that are common to most statistical design problems are briefly discussed. These include one-sided hypothesis tests, power level criteria, equality of within-group variances, transformations of response variables to achieve variance equality, optimal specification of treatment group sizes, ‘post hoc’ power analysis and arguments for the increased use of confidence intervals in place of hypothesis tests.

The Establishment and Application of Open and Innovative Teaching Model of Animal Reproduction, 2012Co-Authors: Wang Li-qiangAbstract:
To meet the demand of innovative talents of society,improve the comprehensive quality and practical ability of college students,and culture the sense of innovation and innovation capacity,the teaching contents of the course of Animal Reproduction were optimized,the experimental teaching program was adjusted,and the models of practice teaching and assessment methods were reformed.The teaching system of Animal Reproduction and teaching effectiveness will be established by using the open teaching resources and exploring the practical teaching system combined production teaching with research.
Study on the Teaching Reform of Animal Reproduction, 2011Co-Authors: Wang Li-qiangAbstract:
Animal Reproduction is one of the most important specialized core course of Animal science major,and it is also a subject with operability,with its theory closely related with practice.In order to help and guide students to grasp new knowledge and content about Animal Reproduction better and faster,stimulate the enthusiasm and interest of students,enforce students’ initiative and improve the teaching effect of Animal Reproduction in a relatively short period of teaching time,the article discussed the teaching system reform of Animal Reproduction from three aspects as the optimization of teaching content,reform of teaching methods and improvement of teaching methods.
Study on the Teaching Reformation of Animal ReproductionJournal of Yangling Vocational & Technical College, 2010Co-Authors: Wang Li-qiangAbstract:
Animal Reproduction is an important specialized basic course of Animal science specialty,with its theory tightly related with practice.It is very important that teachers should help and guide students to grasp new knowledge and content better and faster.In the teaching of Animal Reproduction,it requires that teachers must to improve their own quality unceasingly,rationally design teaching scheme and content,use effective teaching utensils,mobilize the enthusiasm and interest of students,enforce students’ initiative,put the theory into practice and cultivate students’ comprehensive ability,to finally improve the teaching effect of Animal Reproduction

Alpha-fetoprotein in Animal Reproduction.Research in veterinary science, 2019Co-Authors: Annalisa Rizzo, M. Galgano, M. Mutinati, Raffaele Luigi SciorsciAbstract:
Abstract Alpha-fetoprotein (AFP) is a serum glycoprotein with structural and physico-chemical properties similar to albumin. However, the exact physiological functions of AFP remain unknown; those known to date include markers to pathological conditions including neoplastic and non-neoplastic diseases, antioxidant effects, growth regulator in different cells and in cancer, immune response modulator, and carrier for fatty acids and oestrogens. This review aimed to present an overview of the different functions of AFP, particularly its role in the sexual differentiation of the hypothalamus, because its ability to bind oestrogens prevents their passage to the brain, where they inhibit the surge centre development. AFP and anti-Mullerian hormone are known to be involved in the development of freemartins, or genetically female foetuses masculinised in the presence of a male co-twin.
Role of homocysteine metabolism in Animal Reproduction: A review.Research in veterinary science, 2018Co-Authors: Annalisa Rizzo, Raffaele Luigi SciorsciAbstract:
Homocysteine (Hcy) is a thiol-containing essential amino acid, important for the growth of cells and tissues. Several hypotheses exist regarding Hcy toxicity in humans; Hcy is involved in protein structural modifications, oxidative stress, and neurotoxicity induction and is therefore associated with several pathological conditions in humans. In veterinary science, knowledge regarding Hcy has increased recently due to several studies; however, many aspects remain undiscovered. Many details remain unknown regarding the effect of Hcy levels on pregnancy and the optimal management of pathological conditions associated with Hcy levels during pregnancy in various species. In this review, we aimed to compile various studies on Hcy metabolism to elucidate its current status in the veterinary field, particularly for ovine, bovine, equine, porcine, canine, and feline species.
