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...

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 supplementation is known to modify hepatic lipid metabolism in the dairy cow, but little is known about its effect on mammary lipid metabolism. The objective of this study was to characterize the effect of increasing doses of abomasally infused choline on milk production and milk lipids using untargeted lipomics. A total of 12 ruminally cannulated Holstein cows were used in a 4 × 4 Latin square design with 7-d experimental and 7-d rest periods. All cows were fed a common TMR...

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...

1. Introduction Increased atmospheric emissions of greenhouse gases (GHGs), such as nitrous oxide (N 2 O), carbon dioxide (CO 2 ), and methane (CH 4 ), are the primary cause of climate change. These emissions result in unpredictable and erratic rainfall, floods, and droughts [1]. In 2020, agriculture contributed 5865.47 MtCO 2 e, representing 12.34% of its total emissions (47,513.15 MtCO 2 e), including land-use change and forestry...

Traditionally, milk fever prevention programs have attempted to directly alter Ca status of dairy cows at calving. Common approaches include feeding pre-fresh dairy cows diets containing anionic salts, restricting dietary Ca, feeding hyper-dietary Ca and administering Ca boluses. There is an abundance of research in regard to the mechanisms associated with dietary Ca alteration, dietary cation-anion difference as related to parathyroid hormone and vitamin D and the role they play in the...

The quality of the transition period is decisive for the success of the subsequent lactation cycle. Cows with a poorer transition produce less milk, take longer to become pregnant, and are more likely to lose pregnancy and to be culled from the herd, causing substantial economic losses. Investments in infrastructure, personnel, and nutrition focused on prevention and treatment of postpartum health problems, when effective, often result in an excellent return of investment because it...

Grains are the main source of energy to Ruminants as practiced today. But anatomically and physiologically ruminants are designed to digest roughages and fibrous feed to produce VFA's to meet out the major (70%) component of maintenance energy requirements. With the expectation of extra energy supplement for lactation, grains are being fed. But during the process, we create a challenge for animal to forcibly draw energy through grains. Grains are rich in starch...

Introduction Bovine colostrum is largely known for its crucial role in providing the newborn dairy calf with immunoglobulin G (IgG) to establish passive immunity. However, IgG is only one of numerous colostral bioactive compounds – including hormones, fatty acids, and sialylated oligosaccharides (OS) – that have an unrealized potential to positively stimulate calf development (Fischer-Tlustos et al., 2021). In contrast to IgG, many of these bioactive factors...

We’ve previously discussed high-shear dry extrusion of corn and how this process can be used to form highly-gelatinized starch that is quickly degraded in the rumen. Among other things, dry extruded corn has more available energy for productive purposes. This means that more of the energy in corn, following dry...
