ABSTRACT The aim of this study was to analyze the productive and reproductive performance lambs submitted different forms feed supplementation in growth phase breeding season. Twenty-eight Texel sheep aged between three 12 months were used. distributed two treatments with protein-energy at levels 1.6 2.4% body weight reared on Brachiaria brizantha cv. Marandu. evaluated beginning experimental period every 28 days until end season, following data observed: final weight, average daily gain...
Abstract Our hypothesis suggests an improvement in carcass and meat quality of pasture‐finished animals by introducing concentrate feed into diets. This study aimed to evaluate the effect different levels protein‐energy supplementation on characteristics Texel lambs raised Brachiaria pastures, compare results with those obtained from confined animals. Thirty 2‐month‐old intact were divided five treatments: pasture mineral supplementation, containing daily supplies 0.8, 1.6, 2.4% BW...
Five cultivars of Urochloa brizantha (Hochst. ex A.Rich.) R.D. Webster (syn. Brachiaria brizantha) were evaluated for nutritional value and an anti-nutritional factor (protodioscin), in order to determine whether protodioscin content was correlated with reduced feed quality. We cvv. Arapoty, Paiaguas, Xaraes, Marandu Piata grouped the results into summer, autumn, winter spring seasons. Protodioscin chemical composition leaves, vitro digestibility cumulative gas production analysed. Data by...
Abstract: This study was designed to assess the influence of genetic resistance against brachiaria poisoning in sheep. Two groups sheep, one identified as susceptible (formed by two ewes and ram) other resistant three were selected. Sheep considered those that presented clinical signs at any time their life; sheep even raised on Brachiaria spp. pastures, did not developed sign during life. The offspring flocks (15 lambs from sensitive flock 9 flock) placed into pasture (initially decumbens...
The ingestion of pods Enterolobium contortisiliquum is associated with digestive disturbances, photosensitivity and abortion in domestic ruminants. This experiment was designed to test the hypothesis that disturbances this toxicosis are really caused by acute ruminal acidosis. Three sheep fed large doses (10-15 g/kg/body weight [bw]) E. developed acidosis were treated sodium bicarbonate try control metabolic disturbance, thus providing additional evidence involvement pathogenesis toxicosis....
This study assessed the frequency of poisoning by Brachiaria spp. grasses in 34 suckling lambs a creep-feeding treatment supplemented with proteinaceous concentrate and an unsupplemented control group. Samples were collected every 28 days for determining protodioscin content grass. Lambs consistent clinical signs separated from flock, along their dams, fed on hay alfalfa (Medicago sativa) Tifton 85 (Cynodon dactylon) as alternative fibrous feeds. The concentrations 0.3-0.9 0.4-1.4%...
This study aimed to evaluate the nutritional value of Urochloa exotic grasses quantify aspects anti-quality and identify their correlation with quality grasses. We evaluated U. humidicola cv. Comum, BRS Tupi, decumbens Basilisk, D70 ruziziensis ecotype R124, we grouped them into summer, autumn, winter spring. determined chemical composition, in vitro digestibility, levels protodioscin cumulative gas production from leaves grass materials nature. Basilisk showed higher content all seasons,...
The aim of the research was to evaluate productive and reproductive performances ewes as a function supplementation offered suckling lambs. lambs were divided into two experimental treatments. Treatment (1) kept in pastures Brachiaria-grass receiving mineral supplementation; treatment (2) concentrate creep-feeding. Regardless nutritional lambs, all matrices (female ewes) received 350 g daily. Ewes from treatment-1 presented average 49 days return estrus. treatment-2 presented, on average, 36...
The objective of this study was to evaluate the performance, ingestive behavior and gastrointestinal helminths control suckling lambs raised on pastures Brachiaria ssp. supplemented in creep-fed not supplemented. Thirty-one being 15 treatment (without supplementation) 16 creep feeding (with protein-energetic were evaluated. Performance superior no-supplemented. Lambs without had weaning age 81 days an average gain 194 grams. showed 58 daily 268 eggs per gram stool (EPG) count 4553, while...
RESUMO Objetivou-se ajustar e avaliar modelos para predição da composição física química corporal de borregas a partir medidas obtidas seção 9ª à 11ª costelas (seção 9-11) ou 12ª costela. Foram confinadas em baias individuais 36 mestiças alimentadas com níveis crescentes concentrado (0; 20; 40; 60 80%) até atingirem 37,70 ± 10,23kg o abate. No abate, meia-carcaça direita cada animal foi dissecada determinação proporção músculo (PMC), gordura (PGC), osso (POC), proteína bruta (PPBC) extrato...
The aim of this study was to evaluate the effect different inclusion levels semi-purified glycerine in diet feedlot lambs on feeding behaviour, nutrient intake and digestibility, carcass characteristics, meat quality vitro degradability. Thirty-two Dorper × (Texel Suffolk) crossbred intact male (22.2 ± 5.51 kg) were fed (90% purity) at 0, 120, 240 or 360 g/kg dry matter (DM) a total mixed ration with roughage concentrate ratio 40:60 for 84 d. In degradability not affected by supplementation....
It aimed to estimate the forage intake by lambs managed in different leaf allowances on Brachiaria-grass using internal and external markers. Forty-eight Texel with 17.52 ± 3.48 kg were evaluated which 12 testers 36 regulators. The kept twelve paddocks, subdivided into four treatments based green allowance (60, 75, 90, 105 g/kg of BW). experimental design was completely randomised. To dry matter (DMI), following markers used: indigestible (iDM); neutral detergent fibre (iNDF); acid (iADF);...
ABSTRACT: The objective of this study was to evaluate the methods collecting Brachiaria spp. (Simulated Grazing vs. Total Collection) for determination protodioscin concentrations and monitor intoxication in sheep susceptible resistant poisoning by Brachiariaspp. collection done through two different methods. first one consisted throwing a metallic square at 10 random picket points. second performed simulating, with hands, grazing behavior sheep. leaf blades obtained were conditioned forced...
The study evaluated the effects of dietary protein-energy supplementation on feed intake, ingestive behavior, rumen parameters and nutrient digestibility in lambs. Four castrated lambs with 31.9 kg mean body weight fistulated were tested. distributed into latin square design (4x4), four treatments tested over periods time: no (control) or at 8, 16 24 g kg-1 weight. supplement (soybean meal, soybean hulls, ground corn minerals) was provided roughage (Tifton Bermudagrass, Cynodon spp., hay),...
RESUMO Objetivou-se estimar as exigências energéticas de borregas mestiças confinadas, alimentadas com níveis crescentes concentrado na dieta. Foram avaliadas 36 borregas, peso corporal inicial 23,7±3,67kg. Seis animais foram abatidos no início do experimento para obtenção dos valores grupo referência. Os demais (30 animais) distribuídos em cinco tratamentos: mantença (alimentação restrita feno capim Tifton) e suplementados (20, 40, 60 80%) base matéria seca (seis por tratamento). As...
The objective of the study was to evaluate lambs' performance in suckling and finishing phases different nutritional systems. carried out two phases: (from birth weaning) weaning slaughter). Each phase evaluated experimental periods (characterized by year). used 76 lambs divided into groups: control (without supplementation) creep feeding (with feeder supplementation 20 g/kg body weight). were distributed treatments according sex type delivery (single or twin). characterized from slaughter....
Background: Crotalaria spp. Poisoning induces liver or pulmonary disease. C. mucronata, juncea, spectabilis, and retusa are the inducing spontaneous intoxication in livestock Brazil. mucronata juncea associated with interstitial pneumonia, while specatabilis induce hepatotoxicosis. The toxic principle dehydropyrrolizidine alkaloids their N-oxides. incana poisoning to is rarely documented. This paper reports clinical signs pathological findings of a case steer. chemical finding potential...
ABSTRACT: The study evaluate the frequency of poisoning by Brachiaria spp. at rearing, growth and termination stages in various lamb breeds increasing supplementation levels. Forty-five lambs were used phase pastures with a history having induced poisoning. distributed nutritional treatments: receiving mineral (MS), energy/protein (EPS) 0.8% body weight (bw), EPS 1.6% bw 2.4% bw. allotted two flocks (F1 F2) 21 24 each. Clinical signs observed all treatments. All MS died. highest treatment...
