The cactus pear has demonstrated productive potential in arid and semi-arid regions due to its photosynthetic process of crassulacean acid metabolism. Thus, this study aimed evaluate agronomic characteristics chemical composition three genotypes at different locations a tropical semiarid region classified as non-suitable for cultivation. A completely randomized design factorial arrangement (3 × 7) (three [Miúda, Baiana (Nopalea cochenillifera) Orelha de Efefante Mexicana - OEM (Opuntia...
Feeding behavior analysis provides information about the relationships between animals and pastures. Therefore, this review aims to describe some aspects of feeding profiles both sheep goats in grazing systems. The structure pasture is a key factor animals. amount feed consumed given period time affected by number meals, duration velocity swallowing, changes time, bite rate, weight, quality ingested forage. different phenological stages forage also influence animals’ strategies optimize...
Abstract The aim of this study was to assess the effects substituting traditional forage fiber sources with cottonseed cake in diet on both quantitative and qualitative characteristics carcass meat Nelore young bulls. Twenty-four steers starting an average weight 377.8 ± 43.5 kg, were individually housed stalls provided individualized feeding over a 112-day confinement period. followed completely randomized design two treatments 12 replications. diets incorporated either whole plant corn...
Abstract: The objective of this work was to evaluate three tropical forage species for their in vitro methane (CH4) production and organic matter degradability, order determine the relationships between grass nutritive quality CH4 production. Guinea (Megathyrsus maximus), palisade (Urochloa brizantha), signal decumbens) were evaluated. Palisade showed highest matter, neutral detergent fiber, acid lignin, lower-crude protein content. Signal had values hemicellulose fiber-nitrogen,...
Abstract Integrated production systems have been an alternative for diversifying agricultural production, and therefore, it is necessary to study tropical forage grasses that can impact both straw soil organic matter, as well benefit animal production. The objective of this work was evaluate the productive characteristics accumulation nutrients in biomass genus Panicum grown off‐season, Cerrado biome cover plants use integrated systems. It evaluated different maximum : Aruana, Tamani, Massai...
This study was conducted to evaluate changes in hematological biomarkers of Nellore cows at different reproductive stages. Fifteen multiparous with 4 ± 1 years age and live weight 400 50 kg were used stages (non-pregnant, the initial, middle late pregnancy, birth, one day postpartum, 30 60 days postpartum). Blood collections performed every assayed for following biomarkers: hemogram (red blood cells, globular volume, hemoglobin, mean corpuscular volume (MCV) hemoglobin concentration (MCHC))...
The objective of this study was to evaluate the effect Parkia platycephala pod meal (PP) on feeding behavior, rumen health, blood markers, and physiological responses in lactating goats. Eight apparently healthy, adult, multiparous Anglo-Nubian goats, with an average body weight 42.06±3.5 kg approximately 52±4 days lactation, were randomly assigned into two Latin squares (4×4) composed four levels PP (0, 33.3, 66.7, 100% dry matter) for periods. Daily feed intake, [...]
This study was realized to evaluate the effect of concentrate supplementation and time scales evaluation on behavioral physiological responses pregnant ewes grazing system. The experimental design a randomized 2 x 3 factorial arrangement (two breeds: Morada Santa Inês; two levels: 0.5 1.5% body weight; three evaluation: 10, 20 30 minutes) with six replicates per treatment. parameters were influenced by period day breeds, higher values in afternoon Inês ewes. Also, influence found between...
This study aimed to evaluate the buriti oil (Mauritia flexuosa L.) inclusion levels (0, 15, 30, and 45 g kg−1 in dry matter) replacing ground corn on feeding behavior, as well physiological hematological variables of crossbred lactating Anglo Nubian goats. Eight goats were used, which distributed a double 4 × Latin square experimental design (four periods four oil) total matter. For evaluation single animals observed every ten minutes for 24 h three days. Respiratory rate (RR), heart (HR),...
Currently, there is no use for melon plant biomass in agriculture and animal feeding. Using this as silage provides a more sustainable production system. Thus, the objective of study was to evaluate produced with different mixtures ground corn. The experimental design completely randomized factorial scheme (5 × 2) five replications. treatments consisted between (branch + leaf) fruit (melon scrapings) amounts 0% fruit, 5% 10% 20% 100% on an as-fed basis corn AF ensiled biomass. greatest dry...
Current assay evaluates thermoregulatory characteristics of native sheep in pregnancy and supplemented grazing system. Were used 24 multiparous lactating ewes, 12 Santa Inês Morada Nova, with an average weight 52.6 31.3 kg, respectively, were randomly distributed a completely randomized split-split plot design. Physiological parameters such as heart rate (HR), respiratory (RR) rectal temperature (RT) measured that order during the morning afternoon, 06-07 13-14 h, every seven days, totaling...
Current analysis evaluated adaptive parameters and thermal comfort of postpartum ewes fed on concentrate supplementation in grazing system. Thirty lactating pluriparous sheep, 16 Santa Inês (SI) 14 Morada Nova (MN) were used. Physiological such as respiratory rate (RR), heart (HR) rectal temperature (RT) measured, that order, with the animals at rest morning (6:00-7:00 am) afternoon (1:00-2:00 pm), respectively, every seven days, 10 samples. A significant effect (p < 0.05) for RR HR was...
This work aimed to evaluate and correlate the thermoregulatory characteristics of crossbredcows (Holstein x Gir) submitted three different periods exposure solar radiation with somemeteorological variables their effects on milk production. Were twelve lactating cows dividedinto groups consisting four animals each, all third lactation, up five years ageand approximately 50 days radiation.Milk production per cow in kilograms was recorded two daily milkings.
