Evaluation of kernel processing and processor type in whole-plant sorghum silage: effects on nutrient digestibility and animal performance in backgrounding beef heifers.

Two experiments were conducted to assess the effects of feeding whole-plant sorghum silage (WPSS) with different kernel processing techniques (KP). Experiment 1 contrasted KP for WPSS on intake and apparent total tract digestibility (ATTD) in beef heifers (n = 24, 13 ± 1 mo, 267 ± 10.9 kg of initial body weight [BW]) housed in individual pens (36 m2).

Limpograss [] Silage and Protein Supplementation as an Alternative Feed Option for Growing Heifers in North Florida.

Limpograss () is a warm-season perennial grass that has the potential to feed livestock during scarcity periods. This study evaluated the intake, nutrient digestibility, and animal performance of beef heifers fed 'Gibtuck' limpograss silage combined with different levels of a range cube supplementation. Twenty-four heifers (330 ± 16 kg live weight) were submitted to four different treatments with 6 replicates: (1) control, no supplementation + limpograss silage ad libitum; (2) 1.

Supplementation with avian-derived polyclonal antibodies against Methanobrevibacter gottschalkii and M. ruminantium decreases ex vivo methane production and modifies ruminal fermentation in Angus crossbred steers.

The study aimed to investigate the effect of supplementing polyclonal antibodies (PAP) of avian origin against the ruminal methanogens Methanobrevibacter gottschalkii Ho (PAP-Ho) and M. ruminantium M1 (PAP-M1) on ruminal fermentation profile and methane production in Angus crossbred cattle (13 steers and 1 heifer). The experiment was conducted using a randomized block design with a 3 × 2 + 1 factorial arrangement, replicated in 3 periods.

[Use of clinical ultrasound in primary care: Multicenter prospective study].

Objective: The objective was to describe the characteristics of the use of clinical ultrasound in two health centers (SC) of Health Area VII of the Region of Murcia (CS Murcia-Sur and CS Floridablanca).

Design: Observational, descriptive, longitudinal, prospective and multicenter study. SITE: CS Murcia-Sur and CS Floridablanca (Health Area VII of the Region of Murcia).

Monitoring the Effect of Weed Encroachment on Cattle Behavior in Grazing Systems Using GPS Tracking Collars.

Weed encroachment on grasslands can negatively affect herbage allowance and animal behavior, impacting livestock production. We used low-cost GPS collars fitted to twenty-four Angus crossbred steers to evaluate the effects of different levels of weed encroachment on animal activities and spatial distribution. The experiment was established with a randomized complete block design, with three treatments and four blocks.
