Abstract
The growth of the literature on genital diseases in the last decade has been very rapid; therefore, any attempt to canalize this information is to be commended. This book is a large one both in page size (8" x 11") and number of pages 551. Each page is printed by photo-offset method in double column with unadjusted margins. This gives a rather untidy appearance but has the great merit of keeping the cost of printing down. There are 37 illustrations and 19 chapters starting with anatomy and terminating with artificial insemination, of all the domesticated animals. The emphasis is on disease, nutrition and the physiology of reproduction. The author has drawn widely from the mass of published literature, and has provided each section with a list of references. Some readers would have preferred Dr. Roberts' own crystallized opinions with suitable condensation of the more speculative and uncontrolled observations.
In the section on trichomoniasis, which is somewhat over emphasized and over detailed, there is no mention of the use of the vaginal mucus agglutination test introduced by Pierce and by Florent and which in Gt. Britain and on the continent of Europe has been invaluable in herd diagnosis.
In the description of brucellosis the author omits any mention of the local production of antibodies or its diagnostic use and also of the role of the whey test in eradication schemes. He states that milk titres of 1/25 and under are safe. Some workers have found that a certain percentage of these low titres indicate viable infection as shown by guineapig inoculation.
The section on Vibrio fetus is better than the first two sections. The mucus test is described but is attributed to Terpstra although it had been used for some years previously in diagnosis of trichomoniasis by Pierce in Gt. Britain and Florent in Belgium.
In tuberculosis of the uterus it is stated that the tuberculin test may fail to detect those severely affected-surely this refers to a generalized infection and not a purely uterine one. In Gt. Britain experience shows that where tuberculosis has been introduced into the uterus there may be a delay in the appearance of the tuberculin reaction, but once a reaction does occur it is as active as in any other type of the infection.
The chapters on nutrition and its relations to infertility are full of interesting data. That so much of the evidence is uncontrolled emphasizes the difficulty of assessing its value.
With regard to the low plane of nutrition in cattle Roberts stresses the multiplicity of deficiencies which may accrue from low protein diets and that the symptoms of delayed puberty in heifers and anoestrus in cows are identical with those attributed to deficiency of phosphorus. He does not consider that calcium deficiency causes reproductive failures in the cow. In summarizing the section on anoestrus he reflects the feelings of Asdell "that it is a depressing task to gather the literature on the part played by hormones in sterility together" and introduces a great deal of scepticism into this assessment. This section is particularly commended to the reader.
He deals at length with the "Hard to settle cow, " a major problem to the veterinary practitioner, and states that we are still very much on an empirical basis and that more controlled studies are required. The scepticism he evinces towards much of the work on nutrition, hormones, and the treatment of "hard to settle cows" is salutary. He regards as significant the fact that untreated animals often recover almost as well as the treated groups. In discussing infertility in the male he states: "the genetic make up of a sire largely determines his fertility potency" and that only severe disease, nutritional deficiencies, or injuries have important effects on male fertility; this is something that many will agree with.
The book can be recommended for the mine of information and references it includes. The reader will have to assess much of it for his own purpose; the author could have usefully summarized each section and streamlined a great deal of the evidence which is presented in a repetitive and sometimes cumbersome style. He is to be congratulated, however, on tackling such a monumental task and presenting this difficult subject in book form.-W. R. KERR.
