Introduction Biological rhythms are repeating patterns that are driven by time-keeping mechanisms within the animal and are adaptive as they coordinate physiology and metabolism with the external environment. The dairy cow has a well-recognized natural daily pattern of feed intake and milk synthesis and an annual rhythm of milk composition, but regulation of these rhythms has not been well described in the literature or well considered in current dairy management. We commonly...

Alternative technologies offer options to maximize return on investment and maintain milk fat
SAINT CHARLES, MO (June 1, 2022) – Rising global palmitic acid prices may be cutting into dairy farmer margins across the globe. In the U.S., palmitic acid prices have risen 43% over the past 12 months. Simultaneously, the U.S. price of milk fat increased by 61%, creating a unique landscape for dairy farmers to try to balance increasing their income while battling...

Watch this short video and listen to the success story of Italian farm Società Agricola Zilio, 1,100 cows in milk. “We are open to new idea, but they must work. And I must say” - Alex Zilio comments – “that thanks to Balchem ??expertise, and the inclusion of ReaShure-XC and NiaShure in the ration, we saw an increase in milk production of about 2.4 liters/head/day, without forgetting the significant reduction of post-partum events such as retained placenta, dislocation of the abomasum and...

Early-lactation dairy cows have high energy demand for milk production. Often the energy intake in this period is not enough to meet their requirements and the cows often face negative energy balance that may lead to metabolic...

INTRODUCTION Asian buffalo or water buffalo is classified under the genus Bubalus, species bubalis. Buffalo contributes about 12.39% of the total milk produced from all dairy species at global level [1]. On average, 120.15 million tons of milk are produced by buffalo, out of which India and Pakistan contribute 71.7% and 22.71%, respectively [2]. Geographically, Nepal is divided into five plains: Terai plain, Siwalik Hills, Lesser Himalaya, Higher Himalaya and Tibetan...

Importance of animal origin foods and trends of consumption Given their high nutrient density, animal-origin foods have been staples of the human diet along our evolutionary history. Indeed, evidence of meat and bone marrow consumption in hominins can be traced back to around 2.5-2.8 million years ago (De Heinzelin et al., 1999, Thompson et al., 2019). On the other hand, milk from ruminants was introduced into our diets more recently, at least 8500...

Introduction Decisions concerning the milking center are some of the most complicated decisions a dairy producer has to make. Milking procedures, herd size, expansion plans, milking interval and the equity position of a producer influence these decisions. One parlor will not meet the needs of all dairy producers. Producers will have to make the following decisions before they can select or develop management protocols for a milking parlor: 1. How many cows will be milked...

1 Introduction Milk is one of the foods with a crucial nutritional composition for human health. Among the components of milk, fat has been associated with human diseases for years due to its high saturated fatty acid content (Palmquist, 2010). About 70% of the fatty acids in milk triacylglycerols are saturated, 25% are monounsaturated fatty acids (MUFA), and 5% are polyunsaturated fatty acids (PUFA) (Lopes et al., 2016; Abd El-Salam & El-Shibiny, 2020). Studies have shown...

Over the past two decades research in milking management has focused on decreasing the time that units are attached to cows by researching optimal teat stimulation and prep-lag time, pulsation ratios and liner compression and raising automatic take-off settings.
Optimal teat stimulation and prep lag time
Prep Lag time is the time from the start of teat stimulation, to milking unit attachment.
Nearly 50 years ago (1980) Ram Sagi achieved, a higher milk...

Somatic cell count (SCC) is related to the total number of cells per millilitre of milk. Primarily, SCC is composed of leukocytes that are produced by the cow’s immune system during an inflammatory process in the mammary gland, commonly referred to as mastitis (Looper, 2012). This inflammation results from the introduction and multiplication of pathogenic microorganisms in the mammary gland, and a complex series of events leading to reduced synthetic activity, compositional changes and...

Increasing effect on energy efficiency and fertility In dairy farming, especially with high-producing grass-fed cows, the optimisation of rumen fermentation parameters poses an important challenge. In this context, obtaining an adequate dietary energy: protein ratio is a key nutritional goal, not only for the level of performance but also for the fertility of dairy cows. When referring to the relationship between...

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...
