ABSTRACT.
A method is described for obtaining interspecific hybrids between commercial lines of Lotus uliginosus Schkuhr and Lotus corniculatus L. Hybridization was possible between these species using embryo rescue. Two strategies were used to confirm 40 F1 hybrids, that is, flow cytometry and microsatellite simple sequence repeats (SSRs). The L. uliginosus and L. corniculatus parents have significantly different genome size (2.5 ± 0.02 and 2.22 ± 0.02 pg, respectively) and the offspring from the cross had intermediate values. Two SSR primers were polymorphic between the genotypes tested, TM1150 and EH380069. Maternal effect was detected in L. uliginosus genotypes, as determined by greater frequency of F1 hybrids. Recombinant traits were observed in the F1 hybrid progeny. Ninety F1 hybrids resulting from L. uliginosus × L. corniculatus crosses showed different levels of fertility in the polycross; <3% F1 plants produced more than 1000 seeds without embryo rescue while 10% of plants did not flower the first year. The F1 hybrid plants grown under greenhouse conditions exhibited shoot phenotypes similar to L. uliginosus (maternal) whereas F2 phenotypes were similar to L. corniculatus (paternal) in field trials. Rhizome presence was observed in 60% of F2 hybrid plants. The diameters of the root crowns of these plants, however, were similar to that of L. corniculatus.

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).
