It is indeed an honour to be asked to present the 1974 Sir John Hammond Memorial Lecture, and I face this honour with some trepidation knowing the high esteem held for Sir John and his outstanding contributions to world animal science. As most of you know, Sir John was somewhat of a one-man multi-disciplinary team himself, publishing and researching in the fields of animal breeding, reproductive physiology, meat science and animal nutrition. With the rapid and sometimes almost exponential increase in new findings in each of these areas, one person, even one of Sir John Hammond's stature, would now have great difficulty making significant contributions in the several scientific disciplines closely associated with animal production.

Prerequisite Courses

Abstract Anecdotes abound in departmental curriculum committees surrounding the purpose and necessity of prerequisite courses for major subjects. Some believe that a student should have as much exposure as possible to subject matter prior to attempting to gain a full understanding of the material. Others believe that prerequisite courses put an undue burden on students to take excessive coursework and that most of the students’ needs can be provided in a single course. The objective of this study was to ascertain the influence of prerequisite courses in animal science, biology, and chemistry on performance of students in an undergraduate animal science course. In the spring semester of 2019, students taking the animal nutrition course at Tarleton State University were enrolled in the experiment. On the second day of class, students were given a comprehensive exam resembling a final examination to assess knowledge on entry to the course. Subsequently, students completed an online survey to record demographics and educational background in relevant courses. Data were analyzed using PROC MIXED and PROC CORR of SAS v. 9.4. Females had an average score of 39 and males had an average score of 35 on the pre-test, but these numbers were statistically similar (P = 0.16). Student scores on the pre-tests were positively correlated the number of biology (r = 0.52; P < 0.01) and chemistry (r = 0.46; P < 0.01) courses taken, but showed no association (r = 0.14; P = 0.37) with the number of previous animal science courses. Similarly, the number of previously taken biology and chemistry courses were positively correlated (r = 0.70; P < 0.01). Results are interpreted to mean that prior experience in biology and chemistry, but not animal science, are major factors for student performance in animal nutrition and should be considered for prerequisite courses.

This study was aimed to determine the germination process of seeds with different scarification treatments. This research was conducted at the Laboratory of Animal Nutrition, Faculty of Animal Science, Universitas Gadjah Mada, July 2019. The treatment in this research were different scarification methods of the seeds by sanding (P1), wounding (P2), soaking in H2SO4 (P3), soaking in warm water (P4), and baking at 55º C for 10 minutes (P5). Each treatment using 30 long bean seed that has been repeated for 3 times. Based on the five treatments, the seeds were planted in soil media and their growth observed for 14 days. The results showed that the seed growth for 14 days from the five treatments give an indication that the germination process and the first leaves grow out from long bean seeds was happen in treatment by oven 55º C (P5). Based on these results, it can be concluded that different scarification methods affected on the seed germination process. The fastest seed germination process to produce optimum growth in long bean plants was the scarification treatment by heating the seeds using an oven 55º C for 10 minutes (P5) before the seeds were planted.

Editorial noteThe first Hammond Memorial Lecture was given in London in March 1969 by Dr C. P. McMeekan, CBE, formerly Director of the Ruakura Research Centre in New Zealand, afterwards on the staff of, and currently consultant to, the World Bank. Apart from its special interest to those engaged in animal science, the lecture contained much of general interest to natural and social scientists and we are grateful to Dr McMeekan, the Hammond Memorial Trustees and the British Society for Animal Production, under whose auspices the lecture was delivered, for permission to print a substantial portion of it in the Journal of Biosocial Science.Some of the selected material is provocative. For instance, it would be interesting to know the basis of the assumption that world population having risen to 6000 million by the end of this century, will then stabilize. Again, many will disagree with the estimates of unused usable land. But all of the material stimulates thought and we are glad to have the opportunity of publishing it.After discussing the outstanding achievements of Sir John Hammond and the progress of animal science generally, Dr McMeekan continued:

Academic Recognition

<p><strong>Background</strong>: Scientific discoveries have an impact in the cultural notion of the universe and the nature on earth. A discovery has to be published through a careful peer revision, and then recognized by diverse ways. A kind of recognition is the formal citation of the discovery paper on the scientific journals by the different scientists as a reference to discuss the new findings. In a scientific way, plant species discoveries are analogous to the ones on other scientific areas. However, plant discoveries are not cited formally in the plant taxonomy journals. As a result, the papers and the authors are not considered in the bibliographic databases, the general impact indexes, and of course, they are poorly known by most of the academic community. Not surprisingly, plant species discoveries are unimportant for society and decision makers.</p><p><strong>Question</strong>: New plant species discoveries do not have the accurate academic recognition.</p><p><strong>Results</strong>: A scientific discovery recognition analysis was done, by comparing some scientific disciplines against plant taxonomy. A proposal for a formal citation of new plant species publications in botanical journals is presented, so discoveries can be first recognized by the academic community.</p><strong>Conclusion</strong>: New plant species discoveries must have an academic and social recognition, comparable to those of similar scientific disciplines.

Opening Paragraph

Opening ParagraphTo give the first Lugard Memorial Lecture upon Lord Lugard himself is at once a task of great honour and of great difficulty. I need not explain to this audience why it is an honour: we know that we are here to recall the life and work of a great man, who was a creator of our Institute and for nearly nineteen years (1926-45) its Chairman. But the difficulty does need some explanation. I must attempt at least a preliminary evaluation of a life that was immense in the period of time covered and in the range, both in space and in character, of its activities. Yet I cannot assume that you have a full knowledge of that life since its story has yet to be told. Some here knew him in his later years; there are, indeed, some still alive who worked with him in the vigorous days of his prime. There is also his own vivid account of four of his most adventurous early years, and there is the impressive documentation of his governorships. But there are large areas in his youth and even in his manhood which are still quite unknown. And when these have been explored the parts have still to be put together to form a biographical whole. Here is my difficulty: I cannot, in the time we have this evening, attempt both to tell the story, even in outline, and to comment. Yet how can the story and the comment be divorced? I must attempt a compromise. I must offer you something not much more than a chronology of his life, and tell you a little—and how little it must be—of some of his earlier, less known achievements; and then, assuming your knowledge of his later life, offer, in all humility, my first provisional evaluation. I emphasize provisional because my biography is only half drafted and there is much, especially between his leaving Nigeria in 1906 and the latest part of his life when I knew him, that is still, for me, a subject for research.
