Soybean in different forms of processing in the feeding of crossbred cows on brachiaria grass pastures

Vinícius Raimundi Andrade, Fernando de Paula Leonel, Severino Delmar Junqueira Villela, Juliana do Carmo Carvalho, Raphael Pavesi Araújo, Jonas Marco de Carvalho, [...]

DOI: 10.1590/S1806-92902015000200001

The objective was to evaluate intake and digestibility of nutrients, as well as milk production and composition of the milk from F1 Holstein × Gyr cows kept on pasture, supplemented with sugarcane and concentrate (28% CP). Five cows with 150±14 lactation days and average milk production of 7.1±2.1 kg/day were distributed in a 5 × 5 Latin square design. The treatments were: soybean meal-based concentrate; soy bean-based concentrate; ground soybean-based concentrate; roasted soybean-based concentrate; and ground, roasted soybean-based concentrate. Dry […]

DOI: 10.1590/s1806-92902015000200002

The effect of the substitution of Tifton hay (0, 33, 66, 100 g/100 g) for pineapple (Ananas comosus L.) stubble hay was evaluated in the characteristics of the carcasses of goats of an unknown breed (UB) in feedlot. Thirty-two bucks with an average initial live weight of 17.5±1.3 kg, at approximately 150 days of age, were housed in individual stalls provided with feeding and drinking troughs. The animals were distributed in a completely randomized design with four treatments and eight […]

DOI: 10.1590/S1806-92902015000200003

The present study was conducted to investigate the effect of alternative true-protein sources to soybean meal, with different ruminal degradability, using a sugarcane-based diet, on nutrient digestion, ruminal fermentation, efficiency of microbial protein synthesis and passage rate in prepubertal dairy heifers. Eight crossbred rumen- and duodenum-cannulated Holstein × Gyr dairy heifers (202.0±11.5 kg BW) were evaluated in a 4 × 4 Latin square experimental design with four treatments and four periods in two simultaneous replicates. Dietary treatments were: soybean meal; […]

Forage cactus associated with different fiber sources for lactating Sindhi cows: production and composition of milk and ingestive behavior

Carla Aparecida Soares Saraiva, Severino Gonzaga Neto, Lara Toledo Henriques, Maria Fernanda Soares Queiroz, Edilson Paes Saraiva, Rômulo Pontes de Freitas Albuquerque, [...]

DOI: 10.1590/S1806-92902015000200004

The objective of this study was to evaluate the association of forage cactus with different fiber sources (elephant grass hay – EGH; corn straw – CS, hay of cassava shoots – HCS; fresh sugarcane bagasse – FSB; and hydrolyzed sugarcane bagasse – HSB) on the milk yield and composition and the feeding behavior of lactating Sindhi cows. Five cows with average body weight, average daily milk yield, and average daily 4%-fat-corrected milk yield of 265, 4.95 and 5.22 kg, respectively, […]

DOI: 10.1590/s1806-92902015000200005

The objective of the present study was to characterize the food sources, as well as the composition and quality of milk obtained from household farms of western Paraná State (Brazil) with and without technical assistance during the different seasons. For such, 24 properties were selected, 12 of which only received assistance and technical support. Four milk samples were taken (summer, autumn, winter and spring) to assess the physicochemical composition, somatic cell count and total bacterial count and feed supplied to […]
