| Este trabalho objetivou avaliar o comportamento ingestivo e o consumo de forragem de cordeiros em sistemas de terminação a pasto. Os tratamentos foram: cordeiros mantidos junto às ovelhas em pastagem de azevém sem suplementação; cordeiros mantidos junto às ovelhas na mesma pastagem, suplementados em creep feeding; cordeiros mantidos junto às ovelhas na mesma pastagem, suplementados em creep grazing com trevo branco. Foram realizadas três avaliações do comportamento ingestivo, verificando-se as atividades realizadas pelos animais (pastejo, ruminação, amamentação e outras atividades). Houve diferença (p < 0,05) no tempo destinado ao pastejo, à ruminação e a outras atividades, e os cordeiros não-suplementados tiveram maiores tempos de pastejo e ruminação e... |

| This study was designed to investigate the effect of early weaning and concentrate supplementation on performance and metabolic profile of lambs in four production systems on pasture: suckling lambs not supplemented until slaughter; suckling lambs supplemented with concentrate in creep feeding until slaughter; early weaned lambs not supplemented until slaughter; early weaned lambs supplemented with concentrate until slaughter. Performance was assessed by average daily gain (ADG) and body condition score (BCS) measurements. Metabolic profile was delineated by measuring serum albumin, urea, creatinine, cholesterol, glucose and aspartate aminotransferase. Weaning reduced ADG by 92 g/d and the ADG for weaned and suckling lambs were 113 g/d and 205 g/d,... |

| Se realizaron tres experimentos para determinar el efecto de un suplemento con aceite de soya (AS) antes de la inseminación y en periodo postparto (PP), así como el amamantamiento, en el desarrollo folicular, tasa ovulatoria (TO) y eficiencia productiva de ovejas de pelo. En el experimento 1 se proporcionó un suplemento con AS o concentrado comercial (CC) a ovejas en condición corporal alta (CA) y baja (CB): CBAS, CBCC, CAAS y CACC por 14 días antes y 7 días después del empadre, en 2 épocas. En el experimento 2, el suplemento con AS ó CC se proporcionó a ovejas en amamantamiento restringído (AR) y continuo (AC), del día 0 al 32 PP: ACCC, ACAS, ARCC y ARAS. DEl día 8 al 32 PP, las ovejas se examinaron diariamentepor ultrasonografía resgistrando el número,... |

| Se realizaron dos experimentos para evaluar el “efecto macho” y el amamantamiento en el restablecimiento de la actividad ovárica postparto en ovejas Pelibuey. En el experimento 1, se utilizaron 73 ovejas, que se distribuyeron al azar en cuatro tratamientos: T1, amamantamiento continuo sin macho (n=18), crías con madres durante todo el experimento; T2, amamantamiento continuo con macho (n=18), igual que T1 más “efecto macho” (07:00 a 07:30 h y de 16:00 a 16:30 h); T3, amamantamiento controlado con macho (n=18), las crías tuvieron contacto con sus madres en dos periodos (08:00 a 08:30 h y de 18:00 a18:30 h); y, T4, amamantamiento controlado sin macho (n=19). En el experimento 2, se utilizaron 108 ovejas, distribuidas al azar en dos tratamientos: T1,... |

| The aim of our study was to investigate the effects of suckling on reproductive performance and metabolic status of obese (mean body condition score of more than 4.0 on a scale of 1-5) maternal Japanese Black cows during early postpartum period. We used 7 postpartum Japanese Black cattle. Four cows were suckled ad libitum (suckled) until completion of their first artificial insemination (AI), while 3 cows were not suckled at all because they were separated from their calves immediately after parturition (non-suckled). Body weight and plasma concentrations of metabolites and hormones were measured from wk 1 to 9 postpartum. Ovarian activity was detected using plasma progesterone concentration, and all cows received their first AI after application of the... |

| This trial aimed to investigate the influence of calf genetic group on the ingestive behavior of Nellore dams and their offspring on pasture. Twenty one primiparous and multiparous Nellore cows were assigned to the experiment; 13 cows nursed straightbred Nellore calves; and eight cows nursed halfbred Simmental × Nellore calves. The observations started in the morning, as soon as identification of the animals in daylight was possible, and they lasted until after sunset, when identification became impossible. The observations were made at 3, 6, 12, 24 and 30 weeks after calving. The following events were continuosly observed: grazing, rumination, idleness, water and mineral intake, and suckling frequency and length.. The dams of straightbreds showed a... |

| ABSTRACT: This study aimed to describe the management practices used in dairy farms in the south of Brazil, and to understand farmers’ perceptions and attitudes regarding these practices. Farms (n=135) located in all 32 of the municipalities in the northern region of Rio Grande do Sul (Alto Uruguai Gaúcho), Brazil were characterized regarding all calf management practices during a farm visit where farms were inspected and farmers interviewed. In a second visit, 25 in depth interviews were done to understand farmers’ attitudes and perceptions towards these practices and potential influence on calves’ welfare and performance. Management of lactating calves was perceived by most of the interviewees as of marginal importance for dairy activity. In general... |

| Seventy-seven ewes were randomly divided into groups according to parturition season and suckling mode [Rainy season: continuous (n=14) and controlled (n=13); Dry season: continuous (n=25) and controlled (n=25)]. The controlled suckling mode, in both seasons, resulted in a decrease in variables, intervals between parturition and first estrus (reduction of 27.11 and 11.46 days for rainy and dry season, respectively; P<0.05) and between parturition and estrus of conception (reduction of 12.81 and 13.58 days, for rainy and dry season, respectively; P<0.05). As to the lambs, the weight gain was higher in animals subjected to controlled suckling in relation to continuous, especially when lambing occurred in the rainy season (17.83±0.56 vs. 13.95±0.52kg... |
