“…Besides, Yang et al ( 5 ) also found that the inclusion of TA at different doses did not change the plasma concentrations of total protein (TP) and albumin (ALB). By contrast, in the present trial, the abatements of GLB, IgG, CRE, GH, and IGF-1 to different extents were observed when TA was supplemented, which could be linked to the suppressed CP digestibility described above and the possibly consequent protein deficiency, implying that TA addition possibly exerted negative influences on the immune function ( 42 ), muscle mass ( 43 ), and somatotropic system ( 44 ) of goats. In the present experiment, the dietary CP level (7.39% of DM) was relatively low, probably resulting in the adverse effects of TA even supplemented at low doses.…”

The present study was performed to evaluate the impacts of tannic acid (TA) supplementation at different levels on the growth performance, physiological, oxidative and immunological metrics, and ruminal microflora of Xiangdong black goats. Twenty-four goats were randomly assigned to four dietary treatments: the control (CON, basal diet), the low-dose TA group [TAL, 0.3 % of dry matter (DM)], the mid-dose TA group (TAM, 0.6 % of DM), and the high-dose TA group (TAH, 0.9 % of DM). Results showed that the growth performance was unaffected (P > 0.05) by adding TA, whilst the 0.3 % and 0.6 % TA supplementation significantly decreased (P < 0.05) the apparent digestibility of crude protein (CP) and ruminal NH3-N concentration, and raised (P < 0.05) the level of total volatile fatty acid (TVFA) in rumen. The increments of alanine aminotransferase (ALT), triglyceride (TG), cortisol (CORT), total antioxidant capacity (T-AOC), interleukin (IL)-1β, IL-6, and serumamyloid A (SAA), and decrements of globulin (GLB), immunoglobulin G (IgG), cholinesterase (CHE), glutathione reductase (GR), creatinine (CRE), growth hormone (GH), high-density lipoprotein cholesterol (HDLC), and insulin-like growth factor 1 (IGF-1) to different extents by TA addition were observed. Although the Alpha and Beta diversity of rumen bacterial community remained unchanged by supplementing TA, the relative abundance of the predominant genus Prevotella_1 was significantly enriched (P < 0.05) in TAL. It could hence be concluded that the TA supplementation in the present trial generally decreased CP digestion and caused oxidative stress and inflammatory response without influencing growth performance and ruminal microbiota diversity. More research is needed to explore the premium dosage and mechanisms of effects for TA addition in the diet of goats.

“…Urinary chemical composition during the cool season did not vary greatly among treatments. When creatinine was used to quantify urinary volume in this study, the values obtained during the cool season (average, 17.7 L hd −1 d −1 ) were similar to those reported in lactating cows (21.6 L hd −1 d −1 ) (Chizzotti et al, 2008) and in brahman-cross steers (range, 7.7-22.4 L hd −1 d −1 ) (Bruce et al, 2008). When urinary volume excreted was expressed in L ha −1 d −1 , the total amount of urine from steers returning to the pasture was similar across treatments.…”

Nutrient cycling via livestock excreta is an important grassland ecosystem service.This study was conducted in 2016 and 2017 and determined nutrient excretion from cattle grazing three systems: (a) N-fertilized bahiagrass (Paspalum notatum Flüggé) overseeded with rye (Secale cereale L.) and oat (Avena sativa L.) during winter (Grass+N), (b) unfertilized bahiagrass overseeded with rye-oat-clover (Trifolium sp.) mixture (Grass+clover), and (c) rhizoma peanut (Arachis glabrata Benth.)bahiagrass mixture overseeded with a rye-oat-clover mixture (Grass+CL+RP). Urinary volume excreted in the warm season ranged from 122 to 182 L ha −1 d −1 , more than double that in the cool season (56-70 L ha −1 d −1 ). Urinary N concentration during the warm season was greater in Grass+CL+RP compared with Grass+N (4.4 vs.3.1 g kg −1 , respectively). In addition, fecal dry matter and organic matter output was greater for Grass+N than for steers grazing Grass+CL+RP during the warm season (3.8 and 3.2 vs. 2.8 and 2.2 kg hd −1 d −1 , respectively). Total annual feces excretion concentrations of P, K, Mg, and N were greater in the Grass+N than in Grass+CL+RP system. The introduction of legumes increased the proportion of N returning via urine. However, when summed across seasons, total N excretion (feces and urine) was greater in Grass+N than in Grass+CL+RP (89 vs. 71 kg ha −1 yr −1 ), mainly due to the greater stocking rate in the former. Grass-legume systems receiving 34 kg N ha −1 yr −1 recycled 80% of the N recycled in the grass system receiving 224 kg N ha −1 yr −1 , indicating the potential of forage legumes to add N to grasslands.In grazing systems, nutrient cycling is a complex network of interactions between plant growth, type of livestock grazing, grazing intensity, and soil fauna and flora (Burns & Sollenberger, 2001).

“…With this aim, the use of in-paddock technologies in the present study was critical to monitor cattle LWC and MLB intake enabling the integration of the three data streams at a given point in time for individual animals grazing as a group. Previous studies have indicated that associations between the RA of blood metabolites and LWC were affected by animal traits (breed, LW, age, beef, or dairy production), feeding management (grazing pastures, feed lotting), genetics and experimental design 14 , 15 , 18 – 22 . However, the present study is the first to assess the metabolome and performance of grazing beef cattle simultaneously.…”

This study aimed to determine the relationship between the metabolome and changes in growth rate (i.e., liveweight change, LWC) and molasses-lick block supplement intake (MLB) of grazing cattle. Weaner beef cattle were fed for 220 days with a sequence of feed types and blood samples, growth rate, and supplement intake were taken on five points in time. The relative abundance (RA) of plasma metabolites were determined using proton nuclear magnetic resonance (NMR). Sixty-four per cent of the metabolites identified were associated with LWC but only 26% with MLB intake (P < 0.05). Periods with faster growth rate showed high availability of amino acids (i.e., valine, leucine, isoleucine, phenylalanine and tyrosine), acetate, and 3-hydroxybutyrate. Periods with lower growth rate were associated with high RA of lipids, choline and acetate. The metabolic profile of individual animals during a period of compensatory growth (after periods of poor performance) showed that high-performing animals were characterised by lower RA of amino acids (i.e., valine, leucine, isoleucine, methylhistidine), creatinine, creatine, pyruvate, 3-hydroxybutyrate, and acetyl groups. It is speculated that high-performing animals have faster uptake of these metabolites from the bloodstream. Cattle growth rate over time was associated with their metabolome which could be used to ensure that the availability of certain metabolites promoting growth is tailored in feed supplements to improve production.
