Spineless cactus is an important part of dairy cow diet in the semiarid Brazilia. Severe infestation cochineal (Dactylopius opuntiae Cockerell) destroyed a vast area most common species planted region; Opuntia ficus-indica Mill. resistant varieties with superior agronomic performance were recently selected, but they still need to be tested cows. We evaluated use variety, ‘Orelha de Elefante Mexicana’ (OEM, spp.), diet. its effect on intake, nutrient digestibility, microbial protein, blood...
Abstract: The objective of this work was to evaluate the nutritional value erect prickly pear (EPP) (Opuntia stricta), stored for different periods, and its acceptability by Girolando heifers. Five heifers were distributed in a 5x5 Latin square. treatments as follows: EPP without storage time; three post-harvest periods - 7, 14, 21 days; cochineal nopal cactus (CNC) (Nopalea cochenillifera) time, control treatment. diets offered animals composed cacti treatments, well sugarcane silage...
new genotype of spineless cactus is being used in the diets dairy cattle that are raised semi-arid regions. However, little known about its nutritional value. This study aimed to evaluate effects replacing Miúda (Nopalea cochenillifera Salm Dyck) with Orelha de Elefante Mexicana (Opuntia stricta [Haw.] Haw.) cactus, on nutrient intake and digestibility, milk yield composition, feeding behaviour, microbial protein synthesis, nitrogen balance, ruminal blood parameters cows. Ten Girolando cows,...
The aim of this research was to evaluate the effect different concentrate levels in diets based on cactus Opuntia Stricta (Haw.) Haw cladodes over performance lactating Girolando cows.The experiment involved 10 multiparous dairy cows (512.6 kg body weight and producing 13.2kg milk/day), allocated into two 5 x Latin squares. experimental treatments consisted control diet composed by Nopalea cochenillifera. Salm-Dyck. (Nopalea), forage sorghum silage (20% at DM basis), four (20, 24, 28 32%)...
The objective of this study was to evaluate the effect different concentrate levels (40, 50, 60, and 70% on dry matter basis) intake, digestibility nutrients, performance heifers fed sugarcane bagasse as exclusive roughage. Twenty Girolando heifers, with an average body weight 198±25.6 kg were assigned a completely randomized design, established according weight. intake (5.12 7.73 d-1), organic (4.72 7.32 crude protein (0.71 1.05 digestible (3.09 4.77 d-1) linearly increased inclusion in...
Avaliou-se o consumo de nutrientes e desempenho produtivo ovinos submetidos a dietas com níveis crescentes fibra em detergente neutro (FDN): 30; 34; 40 48%. Vinte quatro animais foram distribuídos delineamento inteiramente casualizado, sendo peso inicial utilizado como covariável. Durante 70 dias confinamento, os cordeiros tiveram pesos corporais aferidos as coletas sobras permitiram determinação da ingestão alimentos nutrientes. O matéria seca (g/dia; %PV kgPV 0,75 ) apresentou efeito...
O desempenho produtivo das forrageiras e a relação entre características são determinantes para escolha de cultivares o manejo do pastejo. Objetivou-se com esse trabalho realizar análise comparativa gênero Urochloa determinar associação variáveis produtivas, estruturais químicas, nas condições solo clima Oeste da Bahia. Para isso, foi conduzido um ensaio, em delineamento inteiramente casualizado, seis repetições, sendo avaliadas as decumbens ‘Basilisk’, brizantha ‘Marandu’, U. ‘MG-5...
The aim of this study was to evaluate the effect different dehydration times tomato waste (0, 4, 24, 60 and 96 hours) added in cassava peel silages on density, fermentative losses, dry matter recovery, chemical composition, sensorial quality. material ensiled for days polyvinyl chloride (PVC) silos. There a linear reduction 0.406 kg tonne-1 fresh effluent production silages. A maximum (DM) loss (p<0.01) 7.00% found with 8.10 h wastes. quadratic behavior crude protein (CP) non-fibrous...
The experiments reported in this research paper address the effects of replacing ground corn (GC) with full-fat germ (FFCG) on nutrient intake and digestibility, nitrogen utilization efficiency, performance, predicted methane production dairy cows fed cactus cladodes sugarcane. We hypothesized that inclusion FFCG diet would not alter performance lactating but reduce vivo. Ten multiparous Holstein at 90 ± 10 d lactation yielding 24.2 3.5 kg milk/d were assigned to dietary treatments...
