  • Characteristics of Gas Generation (NH3, CH4, N2O, CO2, H2O) From Horse Manure Added to Different Bedding Materials Used in Deep Litter Bedding Systems
    Journal of Equine Veterinary Science, 2011
    Co-Authors: Felix Garlipp, Engel F. Hessel, Herman Van Den Weghe
    Abstract:

    The aim of this study was to analyze the influence of horse manure added to different Bedding materials on the generation of gases (ammonia (NH3), nitrous oxide, carbon dioxide, methane, water vapor) from deep Litter Bedding under standardized laboratory conditions. Two different types of straw (wheat and rye) and wood shavings were analyzed. The deep Litter (substrate) was made of 25 kg of the respective Bedding material, 60 kg horse feces, and 60 L ammonium chloride solution (urea), and spread out in identical chambers over 19 days (n = 3). On days 1, 8, 15, and 19, total nitrogen, total carbon, and dry matter content of the substrate, as well as the pH in 500-g samples, were measured along with. At the end of each test period, the nitrite nitrogen, nitrate nitrogen, and ammonium nitrogen contents of the leachate were analyzed. The wheat straw substrate emitted the highest concentration of NH3 (4.31 mg/m3; P < .0001) and the wood shavings substrate emitted the lowest (1.73 mg/m3; P < .0001); the rye straw substrate generated 3.05 mg/m3. In addition, significant differences occurred during days 1 to 3 with respect to the generation of the gases NH3, methane, nitrous oxide, carbon dioxide, and water vapor, and after the opening of the chamber on day 15. The nitrogen losses through the leachate occurred mainly in the form of nitrate, where the leachate from the wheat straw substrate had a significantly higher amount of nitrate nitrogen (44.56 mg) as compared with the leachates of the rye straw (14.49 mg; P ≤ .0001) and the wood shaving substrates (22.62 mg; P = .0010).

  • Equine Cyathostominae can develop to infective third-stage larvae on straw Bedding
    Parasites & Vectors, 2016
    Co-Authors: Sandy Love, Eoghan C. Mcgirr, Louise Gordon, Faith Burden, Matthew J. Denwood
    Abstract:

    Background Domesticated grazing animals including horses and donkeys are frequently housed using deep Litter Bedding systems, where it is commonly presumed that there is no risk of infection from the nematodes that are associated with grazing at pasture. We use two different approaches to test whether equids could become infected with cyathostomines from the ingestion of deep Litter straw Bedding.

  • Lying time of dairy cows during the transition period depends on milking system and Bedding.
    2018
    Co-Authors: Wijk, A.s. Van
    Abstract:

    The lying time of high yielding cows is crucial for maximizing milk production and their welfare. When lying down, cows will ruminate and the bloodstream to the udder is larger, which stimulates milk production. The average lying time at farms, according to previous reports, is around 12 hours, while high yielding cows should lie down for at least 14 hours. Automatic milking systems (AMS) allow cows to decide themselves how much time they spend on eating, lying and being milked. The hypothesis is, that they will spend more time on lying than cows housed at farms with a conventional milking system. With the use of sensors, the total duration of the lying time, the amount of lying bouts and the duration of the individual bouts were measured at 14 farms in the Netherlands, from April to June 2016, with conventional milking parlors (n=7) or an AMS (N=7). The farms had free stalls with deep Litter Bedding (N=5) or mattresses (n=9). The results showed that cows housed at farms with a conventional parlor had a longer total lying time (12.2h ± 0.13 (SEM)) per day during the experimental period than cows housed at farms with an AMS (12.08h ± 0.15) and had a higher number of lying bouts (6.7 ± 0.08 (SEM) vs. 6.4 ± 0.09 (SEM) with a shorter individual duration (122.3m ± 2.53 (SEM) vs. 127.1m ± 2.91 (SEM)) (P<0.05). The results of the transition period were split and showed that during the dry period, there is no difference in lying time between conventional and AMS farms: 13.07 ± 0.04 (SEM) vs. 13.12 ± 0.05 (SEM) hours per day. The difference in lying time up to day 6 after calving is 42 minutes where cows at AMS farms lie down for 10.4 ± 0.2 (SEM) hours and cows at farms with conventional parlors for 11.1 ± 0.11 (SEM) hours. From day 19 post-partum the difference in hours was 6 minutes, 10.69 ± 0.016 (SEM) hours for the conventional parlors and 10.59 ± 0.019 (SEM) hours for the automatic milking systems. Cows at farms with deep Litter Bedding had longer lying times than at farms with mattresses throughout the period studied (12.6 ± 0.14 (SEM) hours vs 11.8 ± 0.14 (SEM) hours). The results of this experiment, provides a new insight in the way that cows should be accommodated to optimize the production of milk and welfare status of the individual cow and can function as a standard for future commercial farms with building plans
