O trabalho teve como objetivo definir intervalos de referência para valores metabólitos energéticos, proteicos e enzimáticos em ovinos. Os dados utilizados foram oriundos vários experimentos realizados entre 2006 2018, diversas instituições ensino superior pesquisa. Foi utilizado banco diversificado com observações ovinos diferentes raças, genótipos, idades categorias fisiológicas, criados sistemas manejo. Todos os animais eram saudáveis que apresentaram quaisquer manifestações clínicas...
This study evaluated different herbage allowances from mid to late pregnancy on pre- and postpartum physiological responses, milk production, the performance of Nellore cows preweaning growth their female offspring. Sixty multiparous were blocked by body weight (BW; 425 ± 36 kg) condition score (BCS; 3.67 0.23, scale 1–5) randomly allocated twelve pastures. Treatments consisted two (HA) during pregnancy: low HA (LHA; 2.80 kg DM/kg BW) high (HHA; 7.60 BW). Both treatment groups fed 1 g/kg BW...
Abstract The study investigated the effects of 48-h water and feed deprivation on blood performance grazing Nellore (Bos indicus) heifers. Twenty-four heifers (initial body weight [BW] = 238 ± 10 kg; age 16 2 mo), were ranked by initial BW randomly assigned to one two treatments: (1) animals with free access pasture, water, mineral-mix (CON; n 12), or (2) same conditions but deprived for 48 h (DPR; 12). paddocks consisted Urochloa brizantha cv.

Two studies evaluated the productive characteristics of young Nellore heifers receiving different days on feed (DOF) to determine biological slaughter endpoint. In Experiment 1 (Exp. 1), fifty-one [324 ± 19.3 kg body weight (BW); 16 months] were split into three DOF lengths (45, 75, or 105 days), while in 2 2), thirty-six (362 25.5 BW; 18 months age) 90, 135 days). both studies, all animals distributed complete randomized blocks according initial BW and stratified via carcass ultrasound. The...
The objective of this study was to evaluate the effect adding exogenous enzymes diet on nutrient intake and digestibility, nitrogen balance, ingestive behavior rumen movement ewe lambs. Five lambs, Dorper x Santa Inês crossbred, with an average age 7 ± 1 months, weight 36.40 2.36 kg were assigned in a 5x5 Latin square design. treatments consisted concentrate: Allzyme, Fibrozyme®, Amaize®, Mix Control.

Foram utilizados cinco machos ½ Dorper Santa Inês, não castrados, peso corporal médio 34,5±4,10 kg idade média sete meses. O delineamento experimental utilizado foi Quadrado Latino 5x5. Os tratamentos foram V:C (%) extrusada, sendo as seguintes 30:70, 40:60, 50:50, 60:40 70:30. As variáveis mensuradas consumo...
Abstract The study aimed to evaluate the effect of creep-feeding on growth performance beef young bulls (n = 40) when they were subjected an intensive rearing and finishing system. experiment lasted 325 d, from May/2022 April/2023, calves born in September/2021 supplementation 170 December/2021 May/2022. experimental design used was a randomized block [blocked by body weight (BW) beginning supplementation]. units paddocks (4 per treatment, 5 animals paddock). treatments consisted system or...
The purpose of this study was to evaluate the effects docosahexaenoic in concentrated acid on intake, digestibility, metabolic profile and ingestive behavior lambs diets. Five crossbred Dorper x Santa Inês with initial age body weight average six months 33 kg, respectively, were used trial. animals assigned into a 5×5 Latin square design they received one following treatments: 0, 1.5, 3, 4.5 6 % microalgal product (Aurantiochytrium limacinum algae) or ALL-G Rich® concentrate. diets composed...
Objetivou-se avaliar o efeito da inclusão de fontes lipídicas com diferentes sítios degradação sobre perfil metabólico ovelhas gestantes. O experimento foi realizado na Universidade Federal Uberlândia, Fazenda Experimental Capim Branco, durante os meses agosto a novembro 2015, tendo 90 dias duração. Foram utilizadas 24 gestantes peso corporal médio 50,8±0,7 kg e idade aproximada 12±1 meses. Os animais foram divididos em três tratamentos: Controle, Nutrigordura® Caroço Algodão. volumoso...
As fontes de gordura representam importante componente na alimentação animal. Entretanto, os ruminantes não evoluíram para degradar forma eficiente lipídeos. Visto isso, é necessário estudar como a suplementação desses produtos pode afetar o desempenho dos animais. Objetivou-se avaliar utilização diferentes lipídeos ovelhas gestantes sobre consumo, metabólitos e desempenho. O experimento foi realizado Fazenda Experimental Capim Branco, no setor caprinos ovinos da Universidade Federal...
Abstract The study was carried out to evaluate the effect of water and feed deprivation for 48 hours on performance grazing Nellore heifers. heifers [n = 24; 238±10 kg body weight (BW); 16±2 months old] were randomly distributed in following treatments: (CONT) animals with free access pasture, water, mineral mixture (n 12); (PRIV) maintained under equal conditions; however, deprived 12). managed pastures Urochloa brizantha cv. Marandu from April November 2021. method continuous stocking a...
