Introduction Milk is a liquid consisting of 86-87% water and this means that it is a bulky and heavy commodity. Milk is also produced on a daily basis. As a result, milk requires high cost transportation and there is a cost limit on the range over which it can be sold. It will only keep for a few days, which places a time limit on the period during which it can be used or processed and transformed into more shelf stable products. (Banda, 2010). Milk and milk products play...

In the last 40 years, Israeli researchers realized comparative studies in order to define the negative effect of heat stress in dairy cows and the effect of using cooling methods to mitigate the heat and reduce the losses in the productivity and fertility of the cows during summer. Recently, an index called "summer to winter ratio" was developed in the Israeli dairy sector. This index allows to...

Those days are long gone when cows were enclosed within a pen to restrain their movement. Now they are set free at the farm until brought inside the milking area. As for the milking of cows is concerned, it is no longer a back-breaking job.
Nowadays, milking is done with the help of robotic automation, without involving humans. This method significantly alleviates the workload of dairy farmers.

Take Home Messages Dairy or feed efficiency reflects the level of fat-corrected milk yield produced per unit of dry matter consumed with an optimal range of 1.4 to 1.8 pounds of milk per pound of dry matter. Days in milk, age, growth, changes in body condition score, body weight, forage quality, feed additives, and environmental factors will impact feed efficiency values. Dairy managers should monitor changes in feed efficiency...

We have a renewed interest in the optimal dry period length for dairy cows. The average dry period length in the US is 57 days but variation exists. DHIA data say that on average, 13% of cows are dry less than 40 days and 26% are dry more than 70 days.
The dry period allows the udder to go through a period of involution and ensures that the numbers of mammary cells continue to increase normally during early lactation. The number of mammary cells is a major factor determining milk...

INTRODUCTION Lameness is one of the most important welfare, health, and productivity problems in intensive dairy farming worldwide. Furthermore, it causes pain (Whay et al., 1998; Rushen et al., 2007), reduces longevity (Booth et al., 2004; Canadian Dairy Information Centre, 2014), milk production (Warnick et al., 2001; Green et al., 2002), and reproductive performance (Hernandez et al., 2001; Garbarino et al., 2004), and consequently has a great economic effect (Ettema and...

Dairy sectors all over the world have been using the cattle heat load index (THI) as a mean of characterizing the climatic conditions to which cows are exposed. This is true when analyzing the results of experiments and surveys, as well as the routine by which milk producers operate their farms. The heat load index is based on a formula that includes the ambient temperature and relative humidity at a given time. Until recently, the value of THI 72 had been defined as a threshold value...

Many dairy cows in the developed world are now housed exclusively indoors with fewer than 5% of the 10 million lactating cows in the United States having access to pasture during the grazing season. Indoor housing systems are designed to meet biological needs for food, water, hygiene, and shelter, but surveys of public and farmer opinion suggest that people think that pasture access is also important for the well-being of dairy cows. To determine if pasture...

The "Winter-Summer Ratio" report was developed by Dr. Israel Flamenbaum and Ephraim Ezra. This report reflects the gap in the performance of cows in different seasons and the ability of the individual farm to cope with the negative impact of the summer. The report has been published regularly since 2005, including milk production, fat and protein percentages, SCC, and Conception Rate to all inseminations. For the analysis three...

Cooling means to reduce heat stress from cows was developed over the last four decades in Israel, and are applied to a different degree of success in many farms in the world. Cooling cows in the farm is based on the daily routine, which includes of cooling the cows by a combination of wetting and forced ventilation in the waiting yard and in the feeding line. In addition, cows are force ventilated in resting area. ...

In the pursuit of improved milk yield and production efficiencies, the question has long been asked, when can we best influence a cow’s milk production? For years, the focus has been during the lactation itself, shifting over time to the importance of the transition period. More recently, the importance of early life development has come to the attention of researchers and producers alike.

1. Introduction In the agricultural areas of Venezuela, specifically in Píritu municipality, the main problem in animal nutrition is the energy component of balanced rations, due to the inadequacies of this nutrient and the high cost per unit of energy produced locally. At present, the demand for items used as ingredients for the production of animal feed, such as sorghum is covered up to 60% with imports, as well as 95% soybeans. Because, on the one hand, the...

Summer heat stress causes significant economic losses to the U.S. livestock and especially the dairy industry. Different studies conducted in the United States indicate an annual loss of about $ 1.5 billion to the dairy US industry. This is due to unsuccessful confrontation of US dairy farmers with the heat stress problem. The losses differ of course, between different regions of the United States, with northern temperate climates, the annual milk loss per cow in Midwest...

INTRODUCTION Today’s dairy farms are changing dynamically, with increasing herd size and more hired employees. On larger U.S. farms, there is a reliance on non-family immigrant or contract laborers. Latinos have surpassed African-Americans as the nation’s largest minority group, constituting 17% of the U.S. total population in 2014 (1). This is reflected within the dairy industry, and the increasingly Latino...

Summer losses in milk production are usually related to the negative impact of summer heat stress on the lactating cow. Actually, this is true, due to the large negative effect of heat stress on feed consumption and the efficiency of feed utilization of the lactating cow, as well as on reproductive traits. Recently, it was found that also dry cows, although they are not producing milk, are negatively affected when subjected to heat stress conditions, mainly, due to lower milk and milk solids...

Livestock sector has been considered back bone of Indian farmers. India has cattle and buffalo population of 190.90 and 108.7 million respectively which are major contributors of milk production in the country (19th livestock census, 2012) but, the productivity of our animals are not at par with that of exotic animals. However, it can be improved by better management.
New concepts of dairy farming managerial practices are coming into force these days with their varied benefits. One...
