Pros & Cons of Artificial Insemination in Cattle

Artificial insemination (A.I.) is a common method used to breed cattle. The process involves taking semen collected from a bull and depositing it in a cow. The primary advantage of A.I. is it allows breeders to select from a larger population of sires, making superior genetics available to more than just a few breeding operations. However, properly executing an A.I. program requires specialized knowledge and additional time.

Overview of A.I.

The artificial insemination process starts with the bull. Semen is collected from the bull, extended with a diluent and prepared for storage, if necessary. A veterinarian or A.I. technician then uses instruments to deposit the semen into a cow in oestrus.

Pros of Artificial Insemination in Cattle

  1. It is the only form of mating that allows efficient control of venereal diseases.
  2. It is the most economical method of mating which can be applied. It eliminates purchase of expensive bulls and maintenance costs and prevents possible losses of bulls.
  3. It is the most efficient technique of cattle improvement. One bull can procreate 500 to 8000 progeny per annum while natural servicing provides a mere 30 to 40 progeny per annum.
  4. Adequate progeny is procreated for a reliable evaluation to be made of the breeding value of a bull at a relatively young age.
  5. It necessitates accurate record keeping and a high level of management, resulting in a high degree of efficiency.
  6. Proven bulls are seldom sold, and their frozen semen can be distributed world-wide.
  7. The semen of outstanding bulls can be stored for years and thus used for subsequent breeding programmes.

Cons of Artificial Insemination in Cattle

  1. Venereal diseases can be distributed rapidly as a result of incorrect or negligent handling of A.I. because more cows are involved.
  2. Undesirable characteristics and heritable deficiencies are transferred to more progeny and,
  3. The possibility of inbreeding is much greater than with natural servicing.

Considerations

When deciding between artificial insemination and natural service, cattle producers should consider whether it is an ideal fit for their operation. A.I. requires adequate working facilities and skilled labour. If there is not a veterinarian or A.I. technician in the area it may be cost-prohibitive to use artificial insemination. A breeder needs to figure out if the costs saved by not housing a breed bull are greater than the added costs associated with A.I. However, A.I. may offer an opportunity to greatly increase the herd's genetics that is not available through natural service.

Chinese Cabbage Production

General Requirements Chinese does well in warm seasons of the year. Optimum temperatures for growing are 20ºC to 25ºC, with minimum temperatures of 18ºC and maximum 30ºC. A well-managed chinese crop should yield 5 tons per Lima with a leaf cutting period of 40 to 50 days. First leaves can be harvested 21 days after transplanting. Land Preparation/Soil Type Deep well-drained loamy soils with a pH range from 5.5 to 6.5 is ideal for Chinese cabbage. Effective rooting depth is 60cm. Plough and disc to a 60cm fine tilth seedbed. Avoid planting Chinese cabbage on land previously planted to other brassicas for at least one season. Planting and Transplanting Sow directly by drilling in the farrows 1 to 2cm deep or raise seedlings in nursery beds and transplant 4 to 5 weeks later. Transplant during the cool part of the day (early morning or late afternoon) to avoid wilting of the plants. Space the plants at 20cm between plants and 60cm between rows to give a plant population...
