2. Improvement of Several Traits Selection for one trait seldom leaves other traits of economic importance undisturbed Many production and type traits are correlated genetically i e they are influenced by some of the same genes The primary purpose of the dairy goat is to produce high quality milk efficiently Accordingly milk production must be a major selection goal The more traits that are selected in a breeding program the less the progress that can be made for any single trait Therefore the breeder must restrict his selection emphasis for traits other than milk yield to only those that have economic importance and large Page 155 Identification and Genetics heritabilities to respond effectively to selection Traits which have created shorter life span should be identified for emphasis in the herd breeding program Making Genetic Progess In order to make progress in your herd there are a few key concepts to keep in mind and follow The first concept is to set goals for your herd Where do you want to go with your herd and how do you plan to reach those goals Second as you start your goat dairy work hard at your management practices Fine tune them Depending on what resource you read how well an animal does in your herd is anywhere from 60 to 80 management and 40 to 20 genetics respectively Management is a huge factor in how productive an animal is in your herd The best genetics can not mak
3. Once established in a herd caseous lymphadenitis is difficult to eliminate Even goats in which abscesses are properly lanced and treated will often have recurrences and environmental contamination leads to infection of kids To remove caseous lymphadenitis as a herd problem it is best to cull chronically affected goats Kids should be separated from infected does at birth given pasteurized colostrum from clean does and raised in a clean area on clean pasteurized milk or replacer Some goat herds are using Corynebacterium Pseudotubetculosis Bacterin Toxoid Chapter 5 vaccine and are seeing a reduction in the number of abscesses in their herd Consult with your veterinarian for the proper use of this vaccine Bacteria other than C ovis may be responsible for abscession as a result of contamination of lacerations or punctures These ate usually associated with poor sanitation Corynebacterium pyogenes is frequently responsible for abscesses containing yellowish pus of a mayonnaise consistency Streptococci often produce a watery discharge while staphylococci cause a creamy exudate Although the nature of the pus can give clues to the cause of a particular abscess only laboratory cultural methods can give definite information Page 89 General Herd Health Pinkeye Infectious keratoconjunctivitis or pinkeye is a disease which usually appears in hot dry weather and is spread by close contact and flies Th
4. Probably 10 to 20 of the differences in production between herds is due to genetics The remainder 80 90 is due to environment Season of kidding has a marked influence on milk production Does kidding between December and March have on the average higher milk and fat yields than does kidding later in the year The influence of season of kidding on percentage of fat is considerably less than on yields of fat and milk but does kidding in April to July have slightly higher fat tests than does kidding earlier If comparisons are made between does with records initiated during different seasons they should be adjusted for season of kidding Season adjustment factors in conjunction with correction for age of kidding have been published for each breed Age of kidding affects milk production strongly Age and season of kidding jointly account for 30 to 40 of the total vatiation within a goat herd for milk and fat yields which increase up to 5 years of Page 154 Identification and Genetics age and then decline with advancing age Effects of age on fat percentage are less pronounced Lactation number in addition to the effect of age has a large influence on milk and fat yield in the dairy goat which makes the dairy goat different from the dairy cow The average difference in 305 day milk yields between first and second goat lactations is approximately 300 lbs Hertiability Heritability indicates the relative

FACILITIES Whether the plan is to retrofit a cow milk house or build a new one first select the dairy supply equipment company that will do the actual work The project may be completed by using used equipment from cow dairies An excellent resource to use in the planning phase is the dairy inspector for your area The dairy inspector will need to give final approval on the finished milk house facility and milking system before any milk can be legally shipped Involving the dairy inspector from the beginning may save you time and money The dairy equipment company will need to draw up a plan for your milk handling system and milking parlor area submit it to the state for approval and upon approval they will be able to start work on Chapter 7 the project The United States Department of Health Education and Welfare publishes a handbook titled Grade A Pasteurized Milk Ordinance which covers all aspects of milk production The same rules apply to milk production from both dairy goats and dairy cows Consultation with a dairy inspector will identify those essential building milk handling and equipment handling needs that must be part of a milk production program If desired a copy of the Milk Ordinance may be obtained by writing to Superintendent of Documents Washington DC 20402 There is a charge for the publication In Wisconsin ATCP 60 is the document covering all production regulations Ag 60 wa
13. Handbook Aspects of Dairy Goat Mastitis Mastitis may be defined as inflammation of the mammary gland caused by specific disease producing microorganisms Mastitis in dairy goats like mastitis in dairy cows is a disease of considerable economic importance As in dairy cows infection is usually spread from infected to non infected susceptible animals during the milking process Some aspects of dairy goat mastitis closely resemble mastitis in dairy cows others resemble the disease in sheep Subclinical mastitis may be defined as mammary gland infection as revealed by laboratory examination of milk samples Clinical mastitis is characterized by signs of inflammation swelling pain fever temperature and abnormal milk secretion Clinical cases may be acute where animals clearly show all the characteristic signs of inflammation and chronic where the infection remains in a more or less quiescent state with recurrent mild to severe attacks The most common organism involved in dairy goat mammary disease is Staphylococcus epidermitis which is commonly found on the skin of human Chapter 5 hands and the udder skin of goats This organism produces progressive chronic mastitis very similar to Streptococcus agalactiae infection in dairy cows Recurrent attacks are also possible in which the udder is feverish and painful the quantity of milk secreted is curtailed and the somatic cell count is greatly elevated depending u
14. Overeating Disease but it is not caused by overeating Actually the cause etiology of the disease is the toxin poison produced by the bacterium Clostridium perfringens type C or type D The bacteria are normally present in the soil and the intestinal tract in relatively small numbers Under certain conditions the organisms proliferate reproduce billions of their own kind in the intestine and produce toxin in lethal quantities These conditions are those which 1 provide an ideal environment and food for bacterial proliferation and 2 slow down the normal movement of material through the intestinal tract They are often satisfied by ingesting large amounts of starch when the intestinal tract is not accustomed to it The disease is often associated with lush fast growing pasture or cereal grains heavy grain feeding or access to a lot of milk Illnesses that slow down the intestinal tract may predispose to the accumulation of dangerous quantities of the toxin The predominant predisposing factors in goats have to do with sudden exposure to grain or large increases in quantity of milk consumed without gradually increasing Chapter 5 the amount over several days This leads to indigestion and the slowing of the intestinal tract This probably plays a large role in the disease in goats by allowing more time for toxin to accumulate within the intestinal tract The Type D infection is probably far more common than Ty

Page 100 General Herd Health stressed or exposed to a new species of coccidia This is especially common after the doe has been boarded on another farm for breeding Diagnosis of coccidiosis can be based on clinical signs or microscopic fecal exams Coccidiosis is so common that is should be suspected whenever kids older than about 2 weeks of age are scouring Sudden dietary changes can also cause diarrhea but these make the kid more susceptible to coccidiosis Thus diarrhea that begins with the consumption of too much milk grain or lush grass may drag on for days because of coccidiosis Older kids and adults with diarrhea may have worms tather than coccidiosis or they may have both problems together Oocysts can be identified if the feces are mixed with a concentrated sugar solution The oocysts float to the top along with larger worm eggs They are collected and examined with a microscope Oocysts may be shed in the feces as early as 10 days after a kid is infected but often the first attack of diarrhea occurs before oocysts are available to be identified In these cases the trained technician can do a direct fecal smear to look for smaller merozoites which do not float in the sugar solution If a kid dies of coccidiosis post mortem examination will quickly give the diagnosis The small intestine will have Chapter 5 many irregular raised white areas often about 1 8 to inch in diameter A smear taken
