I decided to write this article following a concrete case, in which I was asked to give an opinion regarding the purchase of fans to cool the cows along the feed line of a certain dairy farm. This manager was 240 meters long and was used to feed (and cool) 320 cows. The dairy owner had two proposals for fans to be installed in the feeding area. The first fan was 50″ in diameter with a 1.5 hp motor and belt drive, with a power consumption of 1.1 kWh. In order to achieve the...

Amino acids (AA) undergo complex metabolism for protein synthesis or excretion after oxidation. We investigated the fate of metabolizable Lys via continuous abomasal infusion of 15 N-Lys. Four rumen-cannulated Holstein cows (147.0 ± 63.2 d in milk, 49.4 ± 9.5 kg milk yield) received 0.6 g/d of 15 N-Lys into the abomasum for 5 d. Cows were offered a common diet (16.6% crude protein; 89% of metabolizable Lys requirement) once daily for an ad libitum intake....

Choline is a methyl donor, which may influence DNA methylation, gene expression, and cellular processes. Past studies have found an increase in milk yield when periparturient dairy cows were supplemented with dietary rumen-protected choline (RPC); however, the mechanism behind this response is unknown. Therefore, the objective of this study was to assess the effects of dietary RPC supplementation on mammary epigenome-wide DNA methylation. Parous Holstein cows were blocked by calving month...

Lecture given as part of bpt (German National Veterinarians Association) meeting 2024, held as part Euro Tier exhibition, Hannover, Germany. The principal factors affecting world dairy sectors in summer are climate change (global warming) and the Increase cow’s productivity. The high yielding cow generates more than 2000 W of heat (like 25 persons), which is much above her capability to dissipate, in a typical summer day. The cow in Germany will...

Lecture given as part of bpt (German National Veterinarians Association) meeting 2024, held as part Euro Tier exhibition, Hannover, Germany. Israel is a small country located in the eastern basin of the Mediterranean Sea. The territory of Israel is 22 thousand square kilometers (Germany is 16 times larger than Israel). Almost two thirds of Israel’s territory is desert and only 20% of it is used for agriculture. Israel population is approximately...

Our objective was to evaluate changes in choline metabolism including bacterial degradation to trimethylamine (TMA), methyl group transfer, and bioavailability in pregnant and lactating cows. Six multiparous, rumen-cannulated Holstein cows were enrolled in a study design where they were abomasally infused 18 g/d choline chloride (CC; dissolved in water; 170 mL/h) for a 5-d experimental period at −3 wk from expected due date and again at 2 wk postpartum. The stable-isotope...

The role of Actisaf® Sc 47 in modern dairy nutrition Improving feed efficiency is one of the most effective strategies to reduce GHG emissions, whilst still increasing milk production. As global demands shift from pursuing maximum output, irrespective of the resources used, to the pursuit of balanced sustainability in which efficient production is measured against environmental concerns and the use of finite resources, so similar changes in approach are...

Global food demand is set to double by 2050 in line with UN estimates that the world population will increase from today’s 7.6 billion to reach 9.8 billion over the next 26 years. To keep pace with such growth, agricultural systems throughout the world will need to provide extra food to feed the rising number of people. While this is a daunting prospect, such enormous growth will also provide opportunities and challenge for the dairy sector as we seek to keep providing the global...

A technique has been established to determine the TMR stability of rumen-protected (RP)-lysine products, but the TMR stability of RPcholine (RPC) products has not yet been explored. The objective of this experiment was to evaluate the TMR stability of 5 RPC products using a modified technique. Triplicate Ziploc bags containing RPC (equivalent of 1 g of choline chloride [CC]), no RPC (negative control), or unprotected CC (positive control; 1 g of CC) mixed with 200 g of TMR (38% DM) were...

The TMR stability of rumen-protected lysine (RPL) products has been previously investigated, albeit without a positive control, potentially introducing bias. The objective of this experiment was to evaluate the TMR stability of 6 RPL products using a modified technique that used an unprotected Lys treatment as a positive control. Triplicate Ziploc bags containing RPL (equivalent of 1 g of Lys), no RPL (negative control) or unprotected Lys-HCl (positive control; 1 g of Lys) mixed with 200 g...

1. Introduction Both L-glutamate (Glu) and L-glutamine (Gln) are abundant amino acids (AAs) in plant, microbial, and animal proteins [1]. In the whole bodies of sheep and cattle, Glu and Gln are the third and eighth most abundant AAs, respectively. For comparison, the total content of these two AAs, along with other AAs, in feeds [e.g., Bermuda grass, distillers dried grains, and solubles (DDGS)], ruminal microbes, and skeletal muscle proteins is also relatively high, as summarized...
