A dairy cattle crossbreeding has been started in 1930s to improve cow milk production, using exotic breeds such as Holstein Friesian and Jersey to exploit breed complementarities of milk production and reproductive traits. Crossbred cows with 50% to 75% blood level able to produce more milk whereas, reproductive performance has decreased as exotic blood level exceeds beyond 50%. Environment and genotype mismatch, lack of appropriate breeding policy and recording system, poor infrastructure, lack of trained man power, improper use of artificial insemination and low adoption of breeding technologies are some of the constraints of dairy cattle crossbreeding in Ethiopia. Defining the suitable breed and blood level for specific production system, continuous skill updating for artificial insemination technicians and introducing appropriate recording system are the most critical points that should be considered during proposing of cross-breeding program for dairy cattle. The purpose of this review was to look at the challenges and opportunities of dairy cattle crossbreeding programs in Ethiopia.

Artificial insemination is very important for genetic improvement, especially in dairy cattle breeds. It has problems in meeting the needs of some producers, not its opportunities. The objective of this study was the challenge and opportunity of artificial insemination on dairy cattle in the case of Sayo district, west Wollega Zone, Ethiopia. The problem of not using Artificial insemination is not limited to the region, and there are also dairy farmers in our district who have not practiced the service due to various challenges. In addition, most of the Artificial insemination services reported by the dairy industry have failed, rather than bull services. However, although there are few attempts to quantify opportunities, constraints, and why producers do not use artificial insemination services in other regions, researchers have not disclosed well-documented data on the challenges and opportunities of artificial insemination services in the Sayo region. The Result is Artificial insemination has played an important role in increasing milk production in the study area because the crossbreed that got good traits from exotic breeds gave high milk than local breed.

In this paper, the potentials and constraints on estrus synchronization (ES) and artificial insemination (AI) practice for dairy cattle producers were overviewed. Compared to other African countries, Ethiopia has large numbers of dairy cattle population. However, the self-sufficiency in milk production is not yet attained due to the presence of a lot of limitations that hamper the success of ES and mass AI practice in many parts of the country such as improper selection of cows/heifers, inseminating a large number of cows/heifers in one day at a specific place (which creates stress for both AI technicians and female animals), absence of a data recording system, lack of clearly defined share of responsibilities among stakeholders, poor communication and collaboration among stakeholders, lack of motivations and skills of AI technicians, lack of support and readily available inputs, feed shortages, improper heat detection by smallholders and time of insemination, and lower reproductive performances of both indigenous and crossbred cows which consequently contributed to the unsuccessfulness of the technology.

Data on body measurements like BL (body length), CG (chest girth), WH (wither height) TM (test day milk production), PM (peak milk production), LP (lactation period), CFDC (cost for concentrate feed before test day milk production per cow), GGU (green grass used before test day milk production per cow) and husbandry practices, were collected from a total of 100 dairy cattle at the villages of Islampur upazila under the district of Jamalpur in Bangladesh from January to February 2017. Collected data were analyzed using SPSS software. The highest BL, CG, WH, CFDC and GGU were 175.71±0.42 cm, 161.74±0.24 cm,123.82±0.11 cm 125.54±0.24 bdt/cow/day and 27.29±0.89 kg/cow/day, respectively. The highest amounts of TM, PM and LP were 9.36±0.60 liter/cow, 13.11±0.54 liter/cow and 247.14±1.47 days/cow, respectively. BL, CG and WH increased with increased of the age of crossbred cattle up to 150 months of old. Similarly, CFDC and GGU increased with the increased of the age of crossbred cattle up to 150 months of old. Farmers in the study area were not interested to keep breeding bulls for breeding purpose but they were using artificial insemination system to inseminate their cows and aware about production performance record of the inseminating bull. Farmers took health services from milk vita and sold milk to the same. They believed that dairy cattle rearing a profitable livelihood. TM, PM and LP increased with the increased of the age of crossbred cattle up to 150 months of old. However, increase of CFDC will increase TM, LP and PM but increase of GGU will increase only LP. On the other hand increase of CG will increase TM and increase of BL will increase LP and PM.Res. Agric., Livest. Fish.4(2): 91-98, August 2017

In temperate regions of Europe where grass grows for most of the year, grazed pasture is the lowest cost feed for milk production. Grazed pasture can make a contribution to dairy cow feeding systems in other parts of Europe, but is less important. While there are many challenges to maintaining or increasing the proportion of grazed grass in dairy cow diets, there are also opportunities to increase its contribution. Grass use and quality can be challenging for several reasons, including the cow and sward interaction, and factors influencing dry matter intake. Adapting grazing management strategies can provide opportunities for incorporating grazing and perhaps increase grazing in dairy cow milk production systems. Pasture management tools and techniques offer the opportunity to increase herbage use at grazing. While there are many benefits of grazing including economic, environmental, animal welfare and social, there are also the challenges to maintaining grazed pasture in dairy cow diets. The objective of this paper is to present an overview of the challenges and opportunities for grazing in dairy milk production systems.

1. An analysis has been made of the association between transferrin genotype and progeny test for both milk yield and fat content in a sample of 879 bulls of five dairy cattle breeds, the majority used in artificial insemination in Great Britain. Although significant effects were found in only one of the ten analyses when the breeds were considered separately, a significant effect on milk yield was found when the results from all breeds were combined. A significant effect was not found for fat content, although the effects of the allele substitutions were in the opposite direction to that on milk yield in five cases out of six.2. Although our results were in the same direction as those of Ashton, the effects were smaller. It was estimated that the locus accounted for 1·1% of the genetic variation in yield and 0·4% of the genetic variation in fat content.3. Some information based on the production records of 178 experimental cows with known genotypes was also analysed. For milk yield, the pattern of effects was similar to that in the sire data though the differences were much larger. The variance removed by fitting constants was not statistically significant for milk yield or fat content. It was estimated that the sire data contained some fifty times as much information as did the cow data.
