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:
Context: Environmental conditions during hot weather decrease feed intake and cattle growth.
Aims: This study conducted over three consecutive years, during the summer, evaluated access to shade as a strategy to mitigate heat stress of finishing cattle in Uruguay.
Methods: Each year, 32 Bos taurus and/or Bos taurus crossbred steers (initially weighing 461 ± 28 kg) were blocked by initial liveweight and assigned to one of eight pens, where one of two treatments were applied, namely, no shade access or shade access (mean shaded area 4.5 m2/animal). Finishing diet was offered three times per day and cattle had ad libitum access to water. Twenty-four pens were considered in a randomised complete-block design. Average daily gain (ADG), dry matter intake (DMI) and feed efficiency were measured, and hot carcass weight was collected at slaughter. Ruminal pH and temperature were obtained using ruminal boluses. Feeding, drinking, rumination, inactive behaviours, respiration rate and painting score were observed.
Key results: Mean days on feed were 70.6 ± 5.5. The average THI ranged from 70 to 72. Steers with access to shade had greater DMI (P = 0.003), ADG (P = 0.004), and feed:gain ratio (P = 0.05) than did not shaded steers. Ruminal pH was higher (P < 0.0001) in shaded than in not shaded animals. The slaughter weight of shaded steers was 10 kg greater (P = 0.02) than that of not shaded steers. A trend (P = 0.06) to higher hot carcass weight after dressing was obtained by shaded steers. The average respiration rate and panting score was consistently lower (P < 0.0001) for shaded than for not shaded steers, except in the early morning. Access to shade increased the time spent by animals feeding (P = 0.008) and ruminating (P = 0.001), decreasing inactive time (P < 0.0001).
Conclusions: Shade could improve performance and welfare of feedlot cattle during summertime, even in regions with an average THI from 70 to 72.
Implications: Access to shade allowed fattening cattle to dissipate heat stored during the day at night and to alleviate the effect of heat load during summer in subtropical region. MenosAbstract:
