The objective of the present study was to evaluate the productive performance and nutritional value of forage of wheat and triticale cultivars at different harvest times in the semiarid region of Minas Gerais. Eight wheat cultivars and two triticale cultivars harvested at three stages of plant development were evaluated: Rubberization, grain at the stage of soft mass and harvest maturation. The experimental design adopted was a randomized block in a factorial scheme 10 × 3, with three replicates, 10 cultivars and 3 developmental stages for plant collection. The main agronomic characteristics and nutritional value were evaluated of forage of the cultivars under study. The study demonstrated the potential of wheat and triticale cultivation for forage in the semiarid region of Minas Gerais. The mean dry matter yield of wheat cultivars was 5.90 t ha-1, 7.85 t ha-1 and 7.98 t ha-1 and triticale 6.47 t ha-1, 9.97 t ha-1 and 10.5 t ha-1 for the rubber harvesting stages, grain at the stage of soft mass and harvest maturation, respectively. For the average crude protein content, the wheat cultivars showed 15.07%, 9.13%, 10.60% and the triticale cultivars showed 14.4%, 9.31% and 10.05% for the harvest stages of rubber formation, grain at the stage of soft mass and harvest maturation, respectively. When evaluating the average levels of total digestible nutrients, the wheat and triticale cultivars showed an average of 48.90% and 48.67% in the rubber harvesting stage and 42.68% and 49.60% in the grain in the mass stage suave and 44.43% and 42.90% at harvest maturation. The highest yield of digestible dry matter was observed with the cultivars harvested at the grain stage at the soft mass stage. Triticale IPR 111 and Wheat IPR PANATY had greater productive potential and better nutritional quality for use as forage.

Potassium and nitrogen are essential nutrients and their uptake and distribution within plants must be coordinated for optimum growth and development. We evaluated the interaction between nitrogen and potassium fertilization on the development of BRS 394 wheat, and the nitrate and ammonium levels in Oxisol soils. A 52 factorial design was used in a greenhouse experiment, with four replicates in randomized blocks, corresponding to five doses of nitrogen (0, 70, 140, 210, and 280 mg dm-3) and five doses of potassium (0, 50, 100, 150, and 200 mg dm-3). The variables analyzed were shoot dry mass; chlorophyll index; nitrate reductase; nitrogen, potassium, and protein concentrations in the leaves; and nitrate and ammonium levels in the soil. There was an interaction between nitrogen and potassium doses on the chlorophyll index, with nitrogen doses between 152.67 and 163.53 mg dm-3 and potassium of 191.50 mg dm-3 providing the highest chlorophyll index. The other variables were influenced separately by the nitrogen dose. The highest nitrate reductase enzyme activity was 1.30 µmol NO h-1 g-1 Fresh Matter, which was reached at a nitrogen dose of 95 mg dm-3. Shoot dry mass, concentrations of nitrogen and total protein in the leaves, and concentrations of nitrate and ammonium in the soil were adjusted to the linear regression model as a function of nitrogen fertilization. The dose of nitrogen that promoted the best development of BRS 394 wheat and the highest concentrations of nitrate and ammonium in Oxysol soils was 280 mg dm-3.

“…Esta práctica incrementa los costos por concepto de alimentación, lo que afecta la sostenibilidad de estos sistemas en su escala económica (Fadul-Pacheco et al, 2013;Prospero-Bernal et al,2017); por lo que incrementar la eficiencia productiva con estrategias de alimentación basadas en el uso de forrajes autoproducidos en las unidades de producción es clave para mejorar los índices económicos y con ello la sostenibilidad de los SPLPE (Martínez-García et al, 2015;Prospero-Bernal et al,2017). En este sentido, prácticas como el uso de ensilados que aseguran una oferta constante de forraje de calidad a lo largo del año, especialmente en épocas críticas, permitirán una intensificación productiva al potencializar la respuesta animal (Mancipe- Muñoz et al, 2021;Plitz et al, 2021). El ensilado de maíz es el ensilado más usado en la región; sin embargo, existe preocupación respecto a su producción.…”

Background: In small-scale dairy systems (SPLPE), multi-species pastures and small grain cereal silages have proven to be an option in the face of potential climate change effects and provide quality forage at low costs in periods of forage shortages. Objective: To evaluate the inclusion of a binary silage of barley and rye, compared to a ternary silage of barley, rye and triticale, in the feeding of dairy cows in small-scale dairy systems, in terms of productive and economic performance. Methodology: In the central Highlands of Mexico and with the participation of a small-scale dairy farmer, the inclusion of these silages in the feed of 6 dairy cows was evaluated under a cross-over design. The treatments included 40% silage (T1, binary; T2, ternary), 36% of conventional feeds (cut pasture, maize straw and alfalfa hay) offered by the participating farmer, and 24% of commercial compound concentrate. The variables evaluated were diet composition, feed intake, yield and milk composition, and an economic analysis made considering feed costs. Results: The neutral detergent fiber content was 4.8% lower in T2 (p<0.05), a treatment that also presented a 3% higher digestibility and a higher metabolizable energy and crude protein content (p<0.05). This was due to the incorporation of the ternary silage, a higher quality silage compared to the binary silage. Energy corrected milk production was higher in T2 (p=0.05), in response to the higher intake and higher digestibility of this treatment. Feeding costs were similar for the inclusion of the two silages and the implementation of the ternary treatment represented an increase of 0.8% in margins over feed costs with compared to the use of the binary silage. Implications. The use of small grain cereal mixtures silages are feasible in small-scale dairy systems to ensure a constant supply of medium quality forage, which together with moderate supplementation can generate high yields and economic income. Conclusions: The inclusion of ternary silage of small grain cereals of barley, rye and triticale, and moderate supplementation with commercial concentrate (24%) and other conventional feeds (36%), is a viable alternative as a feeding strategy in small-scale dairy systems during the dry season maintaining high milk yields and a high profit margin for these systems.
