| Feed shortages are relatively frequent in subtropical pasture-based dairy production systems. The effect of feed restriction on milk yield and physical-chemical traits was evaluated in this study. The experiment was carried out in Brazil's south region. Treatments consisted of control and restricted diet. Six multiparous and six primiparous cows, with 499 ± 47.20 kg body weight (BW), at mid-lactation (188 ± 124 days in milk), producing 19.35 ± 4.10 kg of milk were assigned to two groups, balanced for parity, each group receiving a different sequence of the dietary treatments for 56 days, in a crossover design. Diet nominated as control included 8 kg DM 100 kg BW-1 of Bermuda grass var. Tifton pasture (Cynodon dactylon (L.) Pers.), 5.00 kg of concentrate... |

| 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... |
