“…We collected fecal, blood, and rumen liquid samples and undertook an external parasite check similar to the methods for the in‐house experiment on the final day of the grazing experiment. In addition, we examined fecal samples from all the lambs over the experimental period, and the clinical severity of any diarrhea was scored (Yoshihara et al, 2016). The scores were Level 1: healthy feces (fully formed); Level 2, loss of shape of less than half of the feces; Level 3, loss of shape of more than half of the feces; and Level 4, loss of shape of all of the feces, with watery diarrhea.…”

We proposed a mixture of animal husbandry and fruit tree industry: livestock grazing under an orchard layer to increase agricultural productivity per area and reduce the costs of feed, fertilizer, and weed control. Lambs were reared in-house for 1 month and then moved to a pear orchard for 1 month of grazing. We recorded the changes in body weight, blood properties (e.g., albumin, cholinesterase, and nonesterified fatty acids), and parasitic infection to compare the in-housed lambs with the grazing lambs in the orchard. Additionally, we conducted field investigations for changes in vegetation and soil properties before and after grazing. Grazing caused significant increases in body weight, helminth eggs in dung, and soil water retention, and significant decreases in plant biomass, grass digestibility, and soil hardness. In contrast, the nutritional values of the feed, blood properties, and soil chemical properties (e.g., pH, P, N, and C) were not significantly changed after grazing. These results highlighted that the fruit tree industry combined with livestock production would be an acceptable management approach for Japanese agriculture, although further case studies are required.

Recycling food by-products as animal feed could decrease livestock production costs. We investigated how replacing conventional corn and wheat bran feed (control) with rice bran and soybean curd residue (RBSR) would influence lamb performance and meat quality. Eleven lambs were divided into the control and the RBSR-fed groups. The amount of feed consumed by the lambs, as well as their body weight, nutrient properties (total protein, non-esterified fatty acid, total cholesterol, glucose concentrations) in blood samples, and fecal condition were evaluated. Meat quality (water holding capacity, cooking loss, fat content, and shear force) of their carcasses were also evaluated. Results shows daily body weight gain per lamb in the RBSR-fed group was approximately 2.2-fold than that in the control group. The mean total blood protein and glucose concentrations exhibited increasing trends after feeding with RBSR. In addition, the shear force of the meat was significantly lower and crude fat content was significantly higher in RBSR-fed lambs than in lamb fed the control feed. The study concluded that, RBSR could replace conventional feed for Japanese sheep and can be used to not only reduce feed and disposal costs but also increase animal production and meat quality.

Two experiments were conducted to assess the effects of water medication technology on beef cattle behaviour and performance in tropical conditions. Experiment 1 involved 30 Droughtmaster yearling steers monitored over seven days in a controlled environment. Feed and water consumptions were monitored with Smart Feed Pro® systems, with three water treatments administered via uDOSE® technology. The results indicated an average water intake of 13.6 L/head/d. Experiment 2 had 120 yearling steers from four genetic groups grazing on an extensive pasture system. Throughout four 24-day periods, forage availability and chemical composition were measured once monthly. Experiment 2 revealed a variation in water intake, ranging from 16.2 L/head/d down to 4.75 L/head/d. Notably, the lower intake coincided with a rainfall event documented during the fourth experimental period. Overall, results from both experiments indicated that water medication did not alter cattle water preference. There was no preference for treated water sources in Experiment 1, while differences in Experiment 2 appeared to be influenced by external factors like weather and prior habits. These experiments demonstrate the feasibility of water medication for beef cattle without disruption of their natural behaviour.
