Supplementing calves on deferred native grasslands during their first winter, helps overcoming the nutritive deficits which occur during this season. However, the demand of both qualification and availability of labour may restrain its adoption. The objective of this work was to evaluate calves? average daily live weight gain (ADG) and supplemental feed efficiency (SFE) as a response to self-feeding methods. Two experiments (Exp) were carried out: i) Exp A, on sandy soils with Braford calves
and, ii) Exp B on basaltic soils with Hereford calves. In each experiment 40 castrated male calves were used and randomly allotted to one of two replicates of these treatments: non-supplemented control (C); everyday restricted supplementation (E); restricted self-fed supplementation delivered two times a week (RSF); ad libitum self-fed (ASF). Exp A registered lowest ADG for C (0.155 kg an-1 day-1), similar ADG between E and RSF (0.623 kg an-1 day-1 on average) and highest for ASF (1.135 kg an-1 day-1) (p <0.05). For Exp B, ADG was affected being C ≤ E ≤ RSF < ASF (0.158, 0.390, 0.588 and 1.319 kg an-1 day-1, respectively). SFE values were not different (p >0.05) between treatments for Exp A, even though ASF presented a 50% higher SFE (9.4) than RSF (6.2) and E (6.1). SFE was affected (p <0.05), being ASF (7.7) < E = RSF (3.9 on average). It is possible to overcome winter live weight losses through the combination of deferred native grasslands and restricted self-feeding // La suplementación de terneros en su primer invierno pastoreando campo natural diferido compensa los déficits nutricionales registrados durante esta estación. No obstante, las necesidades de calificación y disponibilidad de mano de obra puede restringir su adopción. El objetivo de este trabajo fue evaluar la ganancia media diaria (GMD) y la eficiencia de uso del suplemento (EUS) como respuesta a métodos de auto-suministro. Se realizaron dos experimentos: i) Exp A, sobre suelos arenosos utilizando terneros Braford y, ii) Exp B, sobre suelos de basalto utilizando terneros Hereford. En cada experimento se utilizaron 40 machos castrados en su primer invierno y fueron asignados al azar a una de las dos repeticiones de estos tratamientos: testigo no suplementado (T); suplementación diaria restringida (DR); suplementados restringidamente dos veces por semana mediante auto-suministro (ASR); suplementados ad libitum mediante auto-suministro (ASA). En el Exp A se registró la menor GMD para T (0,155 kg an-1 día-1), similares valores entre DR y ASR (promedio 0,623 kg an-1 día-1) y la más alta para ASA (1,135 kg an-1
día-1) (p <0,05). Para el Exp B, la GMD fue afectada, siendo T ≤ DR ≤ ASR < ASA (0,158; 0,390; 0,588 and 1,319 kg an-1 día-1, respectivamente). EUS no fue afectada en Exp A (p >0,05), si bien ASA presentó valores 50% superiores que ASR (6,2) y que T (6,1). En el Exp B, EUS fue afectada (p <0,05), siendo ASR (7,7) < DR = ASR (3,9 promedio). Es posible superar las pérdidas peso mediante una combinación de diferimiento de forraje y auto-suministro restringido.

ABSTRACT.
Lotus uliginosus (greater lotus, GL) and L. corniculatus (birdsfoot trefoil, BT) are species markedly different in their genetics, morphology and environmental adaptation. We evaluated the hybrids and parental species under differential conditions: in vitro culture, growth chamber and open field environments. The experimental evaluation included biochemical, physiological, developmental and productive parameters. Parental species exhibited significant differences in root growth under different osmotic potentials generated by polyethylene glycol, and hybrids exhibited variability in their response compared with their parents. Plants grown in pots and subjected to drought exhibited differences in biochemical parameters. Proline accumulation and oxidative damage measured by lipid peroxidation were higher in birdsfoot trefoil than any other genotype, and the lowest values were observed in greater lotus. The total phenolic content in shoot ranged from 147 to 279mg gallic acid equivalents 100g-1 dry mater. With regard to antioxidant capacity estimated by 2,2-diphenyl-1-picrylhydrazyl, greater lotus had the highest value and birdsfoot trefoil the lowest, at almost one-third, whereas hybrids had intermediate values. Under stress conditions, water-use efficiency showed significant differences between both parental species. In the field, under either irrigation or drought, the dry matter accumulated by the hybrids was higher than that of the parents. Hybrids express recombination of features, making them an interesting material to continue evaluation.
