Affords the farmer a chance to contribute in the NationalBreedingprogram through the contract mating program which requires that the Bull dam be registered with the KSB. The colour of the Guernsey varies from yellow to reddish-brown with white patches. They are kind, gentle animals with cheerful dispositions. For traits displaying a lot of hybrid vigor, backcross performance may decline, depending on additive breed merit of the pure breeds involved. The Boran shows a surprisingly straight top line for a Zebu animal. Advantages: Cattle shows, which began in 1828 on Guernsey, hastened the process. So that after some time you will have a record of the family tree of every individual. Some agro-ecological zones (AEZ's) are not suitable for pure breed high yielding milk cows, but can benefit from crossbreeding the local breeds of cattle with exotic breeds. 3. But, even with all this information at our fingertips, it can be hard to distinguish what is important and what isnt. Crossbreeding programs are long-term decisions. This trait has developed over many generations of cattle living close to man. That combination can be higher than the breed merit for that trait of the superior breed in the crossbreds makeup. View all posts by hsotr, Animal Health As its name suggests, the Guernsey cow comes from the Island of Guernsey, one of the Channel Islands located off the coast of France. University of Nairobi Farm PO Box 29053-10202 Kabete The breed became a significant genetic foundation for the American dairy industry, contributing to the general mix of dairy cattle, as well as being used as a purebred. The medium sized Guernsey requires less feed than They make a good family cow because they are a medium size and easy to milk. The first recorded importation of Guernseys occurred sometime around 1830, when a schooner captain named Prince took two heifers and a bull to his home in Boston. The largest herds in Kenya are kept by KARI, Naivasha and El-Karama Nanyuki. This should be one of the first things to consider in a breeding plan: what animal breed fits best to the circumstances on the farm. Dogs Guernsey cattle were first imported to North America in the 1830s, with importations peaking in the late 1800s and early 1900s. Horses Valerie Porter, Lawrence Alderson, Stephen J.G. In small herds inbreeding is a real danger for continued productivity of livestock. It is hardy and adaptable to varied AEZs. In USA reports show that Holsteins cows have been very successfully crossed with Guernsey bulls. Interest in crossbreeding of plants and animals is nearly as old as the science of genetics, dating back to the early 1900s. Heifers generally come into milk at about two years of age.

Without a subpoena, voluntary compliance on the part of your Internet Service Provider, or additional records from a third party, information stored or retrieved for this purpose alone cannot usually be used to identify you. Disadvantages: It can also be crossed with any beef breed to raise beef calves. A distinctive characteristic of the breed is the golden color of its milk, which results from exceptionally high levels of carotene, a precursor to Vitamin A. Drew Conroy, in his book Oxen: A Teamsters Guide, rates the breed highly as a first breed for novice drovers. The bull weighs 600 to 700 kg. Better performance within a breed: If natural breeding is practiced - exchange the bull if the offspring consistently have undesirable traits.

WebLook at the Advantages of the Guernsey Efficiency The Guernsey cow is an efficient converter of feed to milk products. Benefits of crossbreeding depend on good sire selection within the pure breeds, just as purebreds depend on within-breed selection for genetic improvement. Although over 5 billion chickens are raised each year in just the United States to be a source of food in both eggs and meat, that is not the only option that is available to you in poultry farming. It would appear that the Guernsey is currently caught between two conflicting trendsincreasing milk yields to meet the needs of commercial mass production and preserving traditional characteristics to fill the demands of an increasing number of small farms.

Interestingly, it is also just right for making a stable foam in specialty coffees. A survey by Weigel and Barlass, 2003, of U.S. dairy producers already practicing crossbreeding showed that the respondents desired improvements in fertility, calving ease, longevity, and milk component percentages. Drought master cattle breed has advantages like these cattle are free from ticks and are resistant to them. 5. How much milk does the average dairy cow produce in a year? Components fat and protein matter, as do health and fertility, calving ease, calf survival, longevity, and other functional traits. The major disadvantages are that crossbreds also have the weaknesses of the breeds from which they descend and heterosis in initial crosses declines with any backcrossing to parental breeds. Milk production potential is low (10 Kg/day) [4]:3 Imports of French cattle to Guernsey were forbidden by law in 1819, but some importation of British cattle continued until 1877. 12. Unfortunately, Holstein cattle also have disadvantages besides clear advantages in milk production, Ornamental Plants Many other factors, such as body size of mature animals, fertility, calving ease, somatic cell scores, and availability of frozen semen from many bulls with accurate genetic evaluations, also influence breed choices. They stay in the herd longer than any other dairy breed. Guernsey cattle are fawn (a light reddish-brown) and white with hide markings clearly defined.

This theory suggests that there were several breeds of French cattle, some of which had arrived there after a long journey from the Middle East via North Africa and Spain. There are no easy or quick ways to answer the important questions surrounding dairy crossbreeding, but we can use what we do know and be aware of work in progress to give us further direction. Although Guernsey milk was far superior in quality, no breed could outstrip the Holstein for gallons of milk per lactation. Description: Friesians and their crossbreeds are predominant in Kenya particularly in Central Kenya and Central Rift Valley. 5. Purpose:Milk production. Gogar Farm PO Box 6-201080 Rongai The most impressive advantage of wind energy is that it is a form of renewable energy, which means we never run out of supply. Some examples of simple breeding strategies we can mention: 1. The Boran has a useful degree of hostresistanceto ticks and it is reported that the breed is 'completely resistant to buffalo fly'. Buyers want to know the history of theirbreedingstock and how to choose the mates without resorting accidentally to inbreeding through AI, and they are willing to pay for this service. We know less than we need to know about some of the breeds in Table 1 for these characteristics, but we are learning fast as first crosses of Normande, Montebeliarde, and the Scandinavian breeds appear in U.S. dairy herds. Hall, D. Phillip Sponenberg (2016). Heifers generally come into milk at about two years of age. Exact matches only Search in title. Her qualities as the producer of an unique golden coloured milk high in Protein and Butterfat and rich in flavour made her the envy of the emerging dairy industry of the nineteenth and early twentieth centuries. Much of the breeds earliest history is speculative, but the most common theory points to France for the breeds origins. 1. Guernsey are adaptable to all climates and management systems and lack any known undesirable genetic recessives. [4]:1 Cattle were brought to the island in the Middle Ages for draught work. History The crosses involved Holstein, Guernsey, some Brown Swiss and Ayrshire, and a few Jersey animals. This is witnessed by the fact that there is no need for AI companies to indicate 'Calving Ease' bulls in the Guernsey breed. One or two crosses were more profitable than Holsteins across their lifetimes, but only marginally so. It is thought that the Guernsey excels in its ability to absorb this nutrient and transfer it to butterfat. Here is an extract from the Kenya stud book website (need to log in):http://www.klbo.co.ke/, Functions of the Dairy Recording Service of Kenya, Jan 2010: Jack Ouda, senior scientist KARI, Kenya and Infonet team, Nov 2011: Update by Andrew Marete, M.Sc. This knowledge will be important to help dairy producers decide which breeds would be most useful in a crossbreeding program. The Livestock Conservancy is Americas leading organization working to save over 150 heritage breeds from extinction. Borans are generally less affected by foot and mouth diseases than exotics and recover faster. 2. Russell, K. (1980). Description: On that basis, the Holstein breed is in a formidable position. Dairy producers likely looked at the results and concluded that the purebred Holstein cow was close enough to the best choice to eliminate crossbreeding as an option. Trials in Nebraska, USA, show that the Boran and its crosses score consistently better than other Zebu breeds for meat tenderness, carcass marbling and rib eye area. The Jersey's hard black feet are much less prone to lameness. Indirect selection improves a trait by selecting cows with a related trait. The Principles of Dairy Farming. Exact matches only. These cattle are mainly used for the production of milk and secondly for the In fact, the lifetime performance of dairy cows for all traits of economic value should be the ultimate breeding goal. Polled animals are not uncommon and some animals have been selected for this condition. High milk production potential (25 lts/day) withmoderate butter fat content 4.3%. This is of great importance since animalbreedingusually involves more than one trait. Milk has high butter-fat of 4.8% 4. Average weight gains per day on grass & feedlot: Grass = 0.7 - 1.0 kg depending on grass quality. Birdwatching The Guernsey cow is an efficient converter of feed to milk products. Fruit Kenya Aryshire cattle breeders emphasize on medium cow balanced for type, production, longer life and fertility. Besides, researchers can also update data regularly, as needed. 2003. Other genes determine whether the udder will be small or large, whether the animal has horns, the size of the body etc. This provides an early return on investment. Potential milk yield: low to moderate (10-15 liters/day). To increase milk production in zebu cattle: This can be achieved by upgrading the Zebu breed with a proven exotic dairy breed (Jersey, Guernsey, Friesian) upto the fourth generation or the larger and more productive Boran or Sahiwal cow depending on disease pressure in your area. Distinct objectives are essential to a breeding plan aiming to improve our livestock breeds for better future profitability such as: 2. The main disadvantages were (iv) home office constraints, (v) work uncertainties and (vi) inadequate tools. This strategy hasnt been successful at increasing production enough to make the Guernsey competitive with the Holstein, and instead, it has caused the breed to lose some of its genetic distinctiveness. The Guernsey is extremely docile. Make sure the same sire semen is not used on his offspring. Recent references from PubMed and VetMedResource.
