AI Article Synopsis

  • The study explores a new, minimally invasive technique called laparoscopy-assisted abomasal cannulation in bovine fetuses, aiming to improve understanding of ruminant digestion while addressing ethical concerns of traditional methods.
  • The procedure was found to be feasible and efficient, taking an average of 15.5 minutes with minimal tissue damage.
  • Further research is needed to assess the clinical applications and benefits of this technique for collecting abomasal content and other related procedures in veterinary medicine.

Article Abstract

Background: Due to the complexity of ruminant digestion, cannulation of organs of the digestive tract has been carried out in order to advance the understanding of digestive physiology, nutrient degradability, gastrointestinal diseases and biotechnological research. The abomasal cannulation is interesting for nutritional studies, especially in suckling calves, to obtain fluid and abomasal content, evaluation of abomasal flow and function, and infusion of nutrients and drugs when it is intended to reach high concentrations in the organ. Conventionally, access and cannulation of digestive organs of ruminants has been performed by laparotomy, a method often criticized and classified as cruel by some sectors related to ethics and animal welfare. The aim of this present study is to describe and standardize a minimally invasive by laparoscopy assisted abomasal cannulation in bovine fetuses (cadavers), which had been previously slaughtered by accident and would be discarded in local slaughterhouses.

Results: The abomasal cannulation technique was feasible, simple and did not present major difficulties. The surgical time for cannulation of the abomasum, from the insertion of the trocars to the completion of the technique with fixation of the organ to the abdominal wall, ranged from 9 to 27 min, with an average of 15.5 ± 6.62 min.

Conclusions: The Laproscopic assisted abomasal cannulation in bovine fetuses was feasible and safe with minimal tissue injury to the abdominal wall and with short surgical time. More studies in the clinical routine related to minimally invasive abomasal content collection, abomasopexy and abomasotomy are required in order to demonstrate its impact and importance in bovine clinic.

The objective of this experiment was to estimate the bioavailability (BA) of rumen-protected (RP) His, RPLys, and 2 RPMet products using 3 in vivo methods: area under the curve (AUC), plasma dose-response (PDR), and fecal free AA (FFAA) methods. We used 8 rumen-cannulated cows in a replicated 4 × 4 Latin square experiment with 16-d periods. Treatments were (1) abomasal infusion of water (control), (2) abomasal infusion of free His, Lys, and Met (FAA), (3) administration of RPHis + RPLys + RPMet1 (rumen-protected methionine protected with ethyl cellulose; RPAA1), and (4) administration of RPHis + RPLys + RPMet2 (rumen-protected methionine protected with a pH-sensitive polymer; RPAA2).

Background: In cattle, dietary choline is fed in a rumen-protected form to bypass ruminal degradation while allowing intestinal absorption of choline. We require data to help us define choline utilization in the dairy cow transitioning from gestation to lactation.

Objectives: The study examined choline methyl group transfer in dairy cattle transitioning from gestation to lactation.

Two experiments were conducted to determine: 1) the impact of strained rumen fluid (SRF) alone or SRF with particle-associated microorganisms (PAO) included and dilution on in vitro dry matter digestibility (DMD) and 2) the impact of trace mineral (TM) source on in vitro fermentation characteristics and TM solubility under simulated abomasal and intestinal conditions. In experiment 1, 3 cannulated steers were adapted to a diet formulated to meet the nutrient requirements for lactating dairy cows. Strained RF was obtained by straining rumen content through 2 layers of cheesecloth.

The objective of this study was to investigate the interactive effect of DCAD and dietary buffer supply on DMI, ruminal fermentation, milk and milk component yields, and gastrointestinal tract (GIT) permeability in lactating dairy cattle exposed to mild heat stress. A total of 16 lactating Holstein cows, including 8 ruminally cannulated primiparous (80 ± 19.2 DIM) and 8 noncannulated multiparous (136 ± 38.

Our objective was to compare abomasal infusions of linoleic (18:2n-6) and α-linolenic (18:3n-3) acids on the enrichment of n-6 and n-3 fatty acids (FA) into the plasma lipid fractions of lactating dairy cows and evaluate their potential carryover effects in plasma lipid fractions postinfusion. Six rumen-cannulated multiparous Holstein cows (252 ± 33 DIM) were fed the same diet and assigned to 1 of 2 treatments in a completely randomized design with repeated measures. Treatments were abomasal infusions (67 g/d total FA) of (1) n-6 FA blend (N6) to provide approximately 43 g/d 18:2n-6 and 8 g/d of 18:3n-3 or (2) n-3 FA blend (N3) providing 43 g/d 18:3n-3 and 8 g/d 18:2n-6.
