Welcome to the page about Milk quality of Engormix; a source of knowledge on Milk quality.
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...

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 Aflatoxins are mycotoxins of major concern to the dairy industry. Most mycotoxins are found in grain, usually grown in a drought, although they may contaminate pasture grass and occasionally hay. Most frequently, aflatoxins are found in corn (see Figures 1-3) and cottonseed, and sometimes in their byproducts, but also on rare occasions in soybeans or distiller's grain. Peanut products also may be contaminated with aflatoxins and can...

As herds aspire to achieve higher levels of milk production there is a need for more focused management of all areas of the farm. The management of the milking center is no exception to this. In order to achieve success with the milking center the first step is to document what the current baseline is for all the major areas affecting the milking center. During the analysis of this baseline data one important distinction to make is whether the opportunity areas...

Introduction The practical and scientific knowledge obtained on the use of the Lactoperoxidase system (LPs) confirms its innocuity to human health (1), which allowed the lifting of the restriction that the system could not be used for milk products intended for international dairy market, in the Thirty-Second Session of the Commission Codex Alimentarius (2). The simple name of LPs generates confusion due to the association to hydrogen peroxide or oxygenated water, adding without...

Milk is one of Mother Nature’s most perfect foods; however, milk quality is jeopardized when it contains life-threatening pathogens. Through science-based knowledge, procedures have been developed to make milk safer for the consumer without losing its nutritional value. Pasteurization kills harmful bacteria by heating milk to a specific temperature for a set period, eliminating microorganisms responsible for diseases such as listeriosis, typhoid fever, tuberculosis, diphtheria, and...

Introduction At present there are two methods of goat farming in the Czech Republic: Pasture and Indoor farming system. The grazing farming system is widespread especially for smaller herds. The goats are grazed during the day and kept in the stable during the night or in bad weather. Forage from pasture creates only a part of the feed ration, second part is the dry roughages which are added at the stable. The concentrated feeds are mostly served during milking at the...

De Souza et al. (2018) found that the calcium salts of fatty acids treatment increased digestibility, energy allocated to body reserves (0.60 Mcal/d), energy partitioning toward body reserves (1.20 percentage units), and body condition score change (0.06 units), and tended to increase body weight change (0.16 kg/d) and body condition score (0.08 units) compared with Triglycierdes high in palmitic acid

Introduction Consumption of saturated fatty acids in milk and meat from ruminants is associated with an increased incidence of coronary heart disease in human beings (Menotti et al.,1999). The fat from ruminant products is frequently considered harmful to human health due to the high saturated fatty acid content. However, a fat component, the conjugated linoleic acid (CLA) contains anticancer and hypocholesterolemic properties and prevents arteriosclerosis and diabetes...

A new buzz-word is rapidly spreading through the manufacturing and analytical environment. Discussions on the application of Near Infrared (NIR) Spectroscopy are often found on the agenda of production, project, technical and even board meetings. Engineers and chemists are confronted more frequently with the challenge to decide whether a NIR instrument will be the solution to their production quality control and other analytical problems. Are there really amazing machines that can determine...

Benefits of early detachment Faster milking. Early detachment reduces machine-on time. This may or may not result in milking more cows per hour depending on parlour size and milking routine. AMS benefit the most from a short machine-on time. Calm cows. Several studies have observed calmer cows when detaching at a higher flow rate. First lactation cows seem to be more sensible to overmilking than older cows. Improved teat...

Dealing effectively with heat stress in dairy herds is an essential management issue throughout the nation, but Southeastern dairy producers are forced to deal with extreme heat and humidity for prolonged periods. Heat stress decreases feed intake and milk production, decreases milk components including fat, lowers breeding success, and compromises the immune system, which increases the risk for multiple diseases. Hot and humid environments also allow mastitis pathogens to thrive. Below...

INTRODUCTION
In ancient Vedic literature, there are references to indicate that milk and milk derivatives can be used, among other things, for the treatment of human diseases. It is reported that “only desi Indian cow milk contains 24 essential elements – notable among those are copper and gold (Aurum Hydra oxide) which provide energy & immunity power, highly antibiotics & antitoxin”. Of various milk derivatives with medicinal properties,...

Milk quality is considered a welfare issue. Most dairy cooperatives have established quality-based payment programs to provide incentives to improve milk quality (Botaro et al. 2013). Total bacterial count, somatic cell count (SCC), and milk lipid and protein contents are some measurements that either result in the application of a penalty or in the receipt of a premium (Renau 2001). These parameters are also utilised not...
