Great strides have been made in terms of genetic selection for reduced somatic cell, improved resistance to clinical mastitis and higher daughter fertility. But

Unsaturated fatty acids enhance early embryonic development in dairy cows

Source: Alberta Agriculture and Forestry Feeding unsaturated fatty acids has been shown to improve reproduction in dairy cows by decreasing pregnancy losses and increasing conception rates. However, previous studies did not focus on their effects on embryonic development. Two major sources of unsaturated fatty acids are flaxseed and sunflower seeds. Flaxseed is rich in alpha-linolenic

Polled genetics – examine the pros and cons

The calculation and publication of all dairy cattle genetic evaluations in Canada is the responsibility of Canadian Dairy Network (CDN). This non-profit national organization is governed by an 8-member board of directors, the majority being dairy producers. Member organizations include all breed associations, milk recording agencies and artificial insemination centres across Canada as well as

Herd Life and Voluntary Disposals

The aim of Herd Life – Canada’s genetic evaluation for longevity – is to give producers the choice when it comes to removing animals from their herd. In other words, the evaluation is designed to increase voluntary disposals, and as a result, decrease involuntary culling. Evidently, herd disposals are highly related to many non-genetic factors
