The aim of this study was to evaluate the inclusion of alfalfa grazing during 8 h continuous or partitioned in 2 separated sessions of 4 h after each milking, on nutrient intake, digestibility, ruminal fermentation, feeding behavior, milk production, milk composition, and milk fatty acid profile, in late-lactation cows fed a partial mixed ration (PMR). Twelve dairy cows (193 ± 83 d in milk, 584 ± 71 kg of body weight) were housed in individual outdoor pens and assigned to treatments according to a 3 × 3 Latin square design replicated 4 times. The treatments were as follows: (1) control (T0), cows were fed a total mixed ration (TMR) provided ad libitum 20.0% crude protein (CP), 32.2% neutral detergent fiber (NDF); (2) fed a diet combining a PMR which had the same ingredient composition as the TMR (60% of ad libitum intake) + 1 session of 8 h of pasture (T8), continuous grazing alfalfa (Medicago sativa; 20.6% CP, 35.8% NDF) after the p.m. milking; and (3) PMR (60% of ad libitum intake) + 2 daily sessions of 4 h of access to pasture after each milking (T4+4). The experiment lasted 57 d and was divided into 3 periods of 19 d each. The first 12 d of each period was used for diet adaptation, and the last 7 d was used for data collection. No differences among treatments were observed for any of the productive variables, feeding efficiency, or purine derivatives excretion. Cows in T0 had greater intake and apparent digestibility of dry matter, organic matter, and nonfibrous carbohydrates compared with T4+4 and T8. Compared with T0, alfalfa grazing increased the concentration of C18:1 trans-11 and decreased those of C16:0 and C17:0 in milk fat. Cows in T4+4 consumed 1.1 more kg DM/d of alfalfa and N provided by alfalfa in the diet was 3 percentage points higher compared with T8 cows (266 vs. 229 g/d, respectively). In addition, T4+4 cows had a greater daily range of ruminal pH than T8 (0.73 vs. 0.93), and the highest concentrations of NH3-N were recorded during the a.m. grazing session while in T8 cows it occurred during the night. In conclusion, including 8 h of alfalfa grazing in T8 and T4+4 treatments allowed the substitution between 35.8 and 38.7% of the total dry matter intake (DMI) of a PMR (with a similar CP concentration to alfalfa) for pasture, maintaining milk solids production and increasing the C18:1 trans-11 of milk fat compared with a TMR in mid late-lactation cows. In an herbage plus PMR diet, splitting the 1 continuous grazing session of 8 h into 2 sessions of 4 h increased the proportion of energy and N provided by alfalfa pasture and reduced PMR intake, without modifying the total nutrient intake or productive performance of cows. © 2023, The Authors.

Abstract:Amorimia spp. are sodium monofluoroacetate (MFA) containing plants causing sudden death in ruminants. In a previous study, Amorimia rigida caused abortion in one of the five pregnant sheep that received the plant suggesting that it may cause reproductive losses. This work aimed to study the embryotoxic and fetotoxic effects of Amorimia septentrionalis in goats in the Brazilian northeastern semi-arid region. The effects of A. septentrionalis on pregnancy were studied in 16 goats, divided into four groups according to their gestational period. In Groups 1, 2 and 3 the administration of A. septentrionalis at the daily dose of 5g of leaves per kg body weight was started on the 18th, 36th and 93th days of gestation, respectively. Goats from Group 4 did not ingest the plant. When the goats presented severe signs of poisoning the administration of the plant was suspended. Groups 1, 2 and 3 ingested the plant for 7.25±2.87, 9.25±2.21 and 12.50±0.57 days, respectively. All the goats recovered 7-12 days after the end of the administration of the plant. In Group 1, all the goats had embryonic death 6.25±3.59 days after the end of the ingestion of the plant. In Group 2, three goats aborted at 53, 54 and 78 days of gestation. Two goats from Group 3 gave birth normally and the other two aborted at 114 and 111 days of gestation. It is concluded that Amorimia septentrionalis is a sodium monofluoracetate-containing plant that causes embryonic deaths and abortions in goats that ingest non-lethal doses of the plant.
