O eCG é uma glicoproteína secretada pelos corpos endometriais de éguas prenhes, sendo empregada em outras espécies para melhorar o desempenho reprodutivo, pois apresenta afinidade com os receptores dos hormônios folículo-estimulante (FSH) e do hormônio luteinizante (LH). No entanto, benefícios da utilização são evidentes vacas anestro ou escore condição corporal (ECG) ruim. Este trabalho teve como objetivo avaliar efeito aplicação nos niveis séricos progesterona cortisol fêmeas bovinas...
Ruminants have a unique metabolism and digestion of unsaturated fatty acids (UFA). Unlike monogastric animals, the acid (FA) profile ingested by ruminants is not same as that reaching small intestine. The objective this study was to evaluate whole raw soybeans (WS) in diets replacer for calcium salts (CSFA) terms UFA abomasal digesta early- mid-lactation cows. Eight Holstein cows (80 ± 20 d milk, 22.9 0.69 kg/d milk yield, 580 kg body weight; mean standard deviation) with ruminal cannulas...
Sugarcane is relatively affordable in subtropical regions and can be used as a forage source for cattle; however, its low fiber degradation the rumen may impair diet digestibility animal performance. The objective of this study was to evaluate influence fibrolytic enzyme product dairy heifers fed either corn silage or sugarcane silage-based diets on nutrient intake digestibility, eating behavior, energy N utilization, ruminal fermentation, microbial protein synthesis, blood metabolites....
ABSTRACT The objective of this study was to determine the effect increasing monensin doses on intake, nutrient digestion, ruminal fermentation, nitrogen balance, blood metabolites, milk yield and composition lactating dairy cows. Twelve Holstein cows (135 ± DIM; 580 kg BW) were assigned three 4 × Latin square design, with 21-d periods. Cows randomly within each receive one following treatments: Control (C): 0 mg kg−1 DM monensin; Monensin 12 (M12): 24 (M24): 48 (M48): monensin. had quadratic...
The aim of this study was to evaluate the performance and blood parameters Simmental dairy cows, supplemented with 2 g/day ricinoleic acid (RA) in diet.Forty cows mid lactation, individually housed stable type tiestall, were used.The animals randomly assigned two treatments: 0 or g RA/animal/ day.The experimental period consisted 42 days divided into 21-day.It observed reduction dry matter intake (DMI), increased milk, fat FCM (fat corrected milk) yield, as well content milk that received RA...
The aim of this study was to evaluate the fatty acid composition buffalo milk in first eight weeks oflactation. It used 18 cows multiparous Buffaloes Mediterranean race, data collection starting four weeksbefore calving provided by 8th week lactation. animals were mechanically milked once daily themorning. samples for analysis collected weekly from parturition There effect during transition period and early lactation fat yield (kg/day) bodyweight (kg).There on milkfat.Variations levels...
This study aimed to evaluate the effects of using different lipid sources in diets for dairy cows during transition period and early lactation on productive performance physiological parameters Holstein cows. The were fed with following diets: 1) control; 2) Refined soybean oil; 3) Calcium salts unsaturated fatty acids (Megalac-E). Diets formulated meet nutritional requirements pre-partum postpartum period. experimental affected dry matter intake, body weight, condition score, energy balance...
Ricinoleic acid is obtained from castor bean and studies related to its effects on glucose insulin dynamic are scarce in the literature. Eight male Crioulo breed horses (362 ± 16 of live weight, mean SD) were used a replicated 4 × Latin square design experiment that consisted 10 days adaptation 7 for data collection. The allocated each receive one following treatments: Control (0) 1, 2, 3 g/d ricinoleic (diet DM basis). Diets composed commercial concentrate Coast cross hay. Treatments did...
The aim of this study was to evaluate the nutrients balance and milk fatty acids profile dairy cows supplemented with monensin. Twelve Brazilian Holstein were distributed into four balanced 3x3 Latin squares, fed following diets: control (C), basal diet without addition monensin, monensin 24 (M24), 24mg/kg DM 48 (M48), 48mg/kg DM. experimental diets influenced efficiency net energy lactation utilization. A quadratic effect observed for balance. It on nitrogen in yield, composition profile....
The objective of this study was to determine the differences in blood and fatty acid (FA) profile between primiparous multiparous Mediterranean buffaloes cows from 28 days expected calving date until 56 milk. Nine (MUL) 7 (PRI) were used present study, animals grazed Brachiaria decumbens supplemented with 2.0 kg concentrate/day. Blood milk samples collected once a week data submitted repeated measures analysis using PROC MIXED SAS. Multiparous presented higher concentrations glucose...
Este estudo teve como objetivo avaliar os efeitos de suplementação gordura com óleo soja (OS) e sais cálcio ácidos graxos (SC) em vacas leiteiras meio lactação no consumo digestibilidade nutrientes, fermentação ruminal, produção composição do leite balanço nitrogênio. Dezesseis holandesas multíparas (638 ± 73 kg peso corporal 116 26 dias leite) foram utilizadas um delineamento quadrado latino 4 x para as seguintes dietas: cont) controle, sem fonte adicional; OS) 30 g/kg soja; SC1) inclusão...
SUMMARY This study analyzed the effect of including copaiba oil as an additive for cattle supplemented on pasture, during dry season. Four crossbred steers, castrated, with 245 ± 25 kg, aged about 18 months, fitted permanent rumen cannula; were randomly assigned to a 4×4 Latin square. All animals housed in individual paddocks (0.3 ha), uniformly covered Brachiaria brizantha cv Marandu, through and drinking fountain; given concentrate at 500g/100 kg BW containing 380 g/kg crude protein (%DM)....
This research evaluated the effects of diets containing or not deactivated soybean sums on productive performance, carcass attributes, ultrasound, and feed cost in confined heifers with 1/2 Nellore-Angus blood. We used blood from 60 aged 2 25 years a body weight 404.62 kg. A completely randomized design was used, which animals were divided into experimental groups: Cont (concentrated for semi feedlot without added soybean) Bocchi addition soybeans). There no significant difference final...
ABSTRACT: Ensilage of rehydrated corn kernels (RC) has been used to improve nutritional value and facilitate on-farm storage. This study evaluated the effects chitosan lactic acid microbial inoculants on silage microbiology, fermentation profile losses, chemical composition, in vitro degradation, aerobic stability. Forty experimental silos were a completely random design evaluate following treatments: 1) Control (CON): RC without additives; 2) Chitosan (CHI): with 6 g/kg dry matter (DM)...
SUMMARY This study aimed to evaluate the rumen degradability of dry matter (DM), disappearance neutral detergent fiber (NDF) Tifton 85 hay, and fermentation parameters (pH ruminal ammonia nitrogen) sheep fed diets with inclusion safflower grains (0, 7.50 15%). Three mixed breed lambs average body weight 35.50± 1.50 kg were used. The NDF haywas analyzedby DM NDF, kinetic adjusted according first order asymptotic model. samples incubated in descending (96, 48, 24, 12, 6, 3, 0 hours)....

Eighteen were randomly distributed in a completely randomized design. Safflower grain added diets proportions 0.0; 7.5 15%. did not change patterns eating, leisure, or rumination; however, it improved efficiency NDF ingestion, by 26%. head temperature decreased 1.5 ° C include 7.5% safflower; rectal quadratically addition (39.5 and. 39.08 C).
