Production Period of Different Browse Species Suitable for Grazing Small Ruminants

Abstract Browse (shrubs, trees, and vines) species are important sources of feed for small ruminants in Alabama and many other states of the U.S. Information on the production period of these species is important to prepare a year-round grazing plan to utilize them well. The objective of the study was to determine the leaf-shedding time of common browse species suitable for small ruminants. This study was conducted at the Atkins Agroforestry and Browse Research and Demonstration Site of Tuskegee University, Alabama. Ten samples of each browse species were tagged, and leaf-yellowing and leaf-fall data collected using photoplots every 14 days until all leaves were shed. Out of 31 species studied, four were early shedders and four were evergreen species. The variation in leaf-shedding time among browse species can be useful for selecting suitable species to incorporate into the grazing systems and utilizing them well.

Legume-Grass Pastures Enhanced the Growth of Yearling Kiko Does

Legumes can be beneficial in increasing pasture productivity and goat performance. This study’s objective was to evaluate the impact of legume-grass pastures on goat performance. A 50:50 mixture of hairy vetch (Vicia villosa Roth) and Marshall ryegrass (Lolium L.) or hairy vetch and rye (Secale L.) was sown on 50% of the research area and 50% with Marshall ryegrass or rye. Forage samples were collected and processed for dry matter. Yearling Kiko does (19) were divided into two groups: legume-grass mix (10 does) and grass only (9 does), both rotationally stocked in their respective plots. Animal live weight, FAMACHA score, and body condition score were collected at the beginning, fortnightly, and at the end of the study. The goat group on legume-grass pasture gained more weight (67 ± 0.9 lb.) than the group on the grass pasture (65 ± 0.9 lb.) (

Deep Learning Methods for Tracking the Locomotion of Individual Chickens

Poultry locomotion is an important indicator of animal health, welfare, and productivity. Traditional methodologies such as manual observation or the use of wearable devices encounter significant challenges, including potential stress induction and behavioral alteration in animals. This research introduced an innovative approach that employs an enhanced track anything model (TAM) to track chickens in various experimental settings for locomotion analysis. Utilizing a dataset comprising both dyed and undyed broilers and layers, the TAM model was adapted and rigorously evaluated for its capability in non-intrusively tracking and analyzing poultry movement by intersection over union (mIoU) and the root mean square error (RMSE). The findings underscore TAM’s superior segmentation and tracking capabilities, particularly its exemplary performance against other state-of-the-art models, such as YOLO (you only look once) models of YOLOv5 and YOLOv8, and its high mIoU values (93.12%) across diverse chicken categories. Moreover, the model demonstrated notable accuracy in speed detection, as evidenced by an RMSE value of 0.02 m/s, offering a technologically advanced, consistent, and non-intrusive method for tracking and estimating the locomotion speed of chickens. This research not only substantiates TAM as a potent tool for detailed poultry behavior analysis and monitoring but also illuminates its potential applicability in broader livestock monitoring scenarios, thereby contributing to the enhancement of animal welfare and management in poultry farming through automated, non-intrusive monitoring and analysis

Results indicated that legume-grass pastures promote the performance of growing does compared to sole-grass pastures

Effect of silvopasture system on fearfulness and leg health in fast-growing broiler chickens.

A silvopasture system intentionally integrates trees, forages, and livestock, allowing dual land use. These systems can provide high-quality habitat for broiler chickens; however, such systems have not been widely adopted by the broiler industry in the United States. The objective of this study was to examine the effect of silvopasture versus open pasture access on fearfulness and leg health in fast-growing broiler chickens. A total of 886 mixed-sex Ross 708 chicks in Experiment 1 (Exp 1) and 648 chicks in Experiment 2 (Exp 2) were housed in coops and had access to 16 (Exp 1) or 12 (Exp 2) 125m2 silvopasture plots (x̄ = 32% canopy cover) or open pasture plots (no canopy cover) from day 24 of age. Fearfulness was measured using a tonic immobility test (tonic immobility duration), and leg health was assessed by quantifying footpad dermatitis, hock burns, gait, and performing a latency-to-lie test on days 37-39 of age. Birds in the silvopasture treatment were less fearful than birds in the open pasture treatment. Overall, birds in both silvopasture and open pasture systems had excellent leg health. Silvopasture birds had lower footpad dermatitis scores than open pasture birds. Silvopasture birds tended to have worse gait than open pasture birds in Exp 1, but not in Exp 2. Hock burn scores and latency-to-lie did not differ between treatments in Exp 1 or Exp 2. Raising birds in silvopasture reduced fear and improved footpad health compared to birds raised in open pastures, which indicates that silvopasture systems provide some benefits for affective state and leg health in fast-growing broilers
