This meta-analysis aimed to identify knowledge gaps in the scientific literature on future fetal-programming studies and investigate factors that determine performance of beef cows their offspring. A dataset composed 35 publications was used. The prenatal diet, body weight (BW), average daily gain (ADG) during pregnancy, calf sex were elicited as possible modulators offspring performance. Then, correlations between these variables outcomes interest investigated. mixed multiple linear...
Dairy farm decision support systems (DSS) are tools which help dairy farmers to solve complex problems by improving the decision-making processes. In this paper, we interested in newer generation, integrated DSS (IDSS), additionally and concurrently: (1) receive continuous data feed from on-farm off-farm collection (2) integrate more than one stream produce insightful outcomes. The scientific community allied have not been successful developing, disseminating, promoting a sustained adoption...
A survey to explore the challenges and opportunities for dairy farm data management governance was completed by 73 farmers 96 non-farmers. Although 91% of them find sharing beneficial, 69% are unfamiliar with collection protocols standards, 66% feel powerless over their chain custody. 58% share data, only 19% recall having signed a agreement. Fifty-two percent respondents agree that collected on belongs farmer, 25% believing intellectual property products being developed 90% all said...
Cold stress negatively impacts the welfare of calves in outdoor hutches. No studies have examined potential benefits pair housing to buffer against cold stress. Our study evaluated effects vs. individual on thermoregulatory, behavioral, and growth performance responses hutches during a Wisconsin continental winter. Forty-Eight Holstein-Friesian heifer were enrolled into 1 2 treatments: individually (n = 16 calves) or housed pairs; 32 calves). Calves fed milk 2x/d with ad libitum access...
Dairy farmers face increasing pressure to reduce greenhouse gas (GHG) emissions [i.e., carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O)], but measuring on-farm GHG directly is costly or impractical. Therefore, the dairy industry has relied upon mathematical models estimate those emissions. However, current tend be not user-friendly, difficult access sometimes very research-focused, limiting their practical use. To address this, we introduce DairyPrint model, a user-friendly tool...
The effects of the salt-to-metal catalyst ratio and amount digestion mixture on total nitrogen content in different materials using Kjeldahl method were evaluated. Four samples with low contents four high analyzed. study evaluated two ratios salt (sodium sulfate) to metal (copper (10:1 20:1) three amounts per sample (1.0, 1.5, 2.0 g 200 mg-1). There was an interaction between low-nitrogen material contents. Samples cattle feces corn presented higher when 1.5 used. high-nitrogen However,...
Precision feeding is an excellent alternative to conventional phase systems for growing-finishing pigs, especially with increasing costs and environmental sustainability concerns. However, precision strategies sometimes require advanced technologies such as electronic devices the modernization of pig facilities. In addition hardware implementation, frequently related mathematical difficulties due a lack professionals trained in decision making. Therefore, this study compares model (CON)...
We aimed to test the associative effects among forages, and between forage concentrates on in vitro digestibility of dry matter neutral detergent fibre using an artificial ruminal fermentation system. The study consisted two assays, which were evaluated three sugarcane, maize silage, Tifton 85 hay under incubation conditions (single feed or all feeds together a jar), sugarcane soybean meal and/or ground maize. For first assay, increased (p < 0.02), whereas silage decreased 0.01) when...
Our objective was to propose and evaluate a standard procedure for the evaluation of in vitro dry matter digestibility ruminant feeds, using artificial fermenters. A collaborative study performed with seven feed analysis laboratories four feeds (Tifton 85 hay, corn silage, soybean hulls, meal). Two types fermenters were evaluated (DaisyII Ankom TE-150 Tecnal). Each laboratory received 80 sealed filter bags samples (20 per feed), eight blank bags, plastic bag buffer solution reagents,...
Research on the use of heart palm by-product (HPB) as a feed for dairy cattle is needed since it low-cost alternative in addition avoiding environmental contamination. The objective this study was to evaluate intake, digestibility, milk yield and composition from cows fed HPB. Sixteen Holstein were used. Treatments consisted fresh sugarcane replacement (dry matter basis – DM) HPB at levels 0%, 7.5%, 15% 22.5%. Experimental design randomized blocks with measures repeated time, data compared...
Our objectives were to evaluate the variability among animals regarding degradation rate of potentially degradable fraction dry matter, crude protein, and neutral detergent fiber, as well establish minimum number provide a standardized design sampling times for in situ ruminal assays tropical feeds with cattle. Seven evaluated, four concentrates three forages. The incubations performed using five rumen-cannulated Nellore heifers (328 ± 9.8 kg body weight). complete sets incubation...
Objetivou-se neste trabalho propor modelo para predição da fração digestível fibra em detergente neutro (FDN) de forragens e concentrados ofertados bovinos manejados clima tropical como alternativa ao adotado pelo Sistema BR-CORTE. Foram conduzidos dois estudos. O primeiro estudo foi conduzido objetivando-se construir modelos que permitam o fracionamento FDN quanto potencial degradação ruminal utilizando-se características químicas. utilizadas 371 amostras 65 concentrados. Os construídos...
This study evaluated the effect of crude protein (CP) reduction in four diets (156, 139, 132, and 127 g Kg-1 DM) maintaining constant metabolizable (188 g/day) on follicular fluid cumulus-oocyte complexes mid-lactating Girolando cows. Twenty-two cows with average 21.55 ±3.19 L daily milk yield, 105.30 ±22.62 days lactation 3.22 ±0.03 body condition score were selected. To reduce CP maintain protein, urea soybean meal gradually replaced by lignosulfonate-treated (SoyPass®, Cargill), resulting...
