Supplementation of urea to a basal pasture diet fed to dairy cows to model N-partitioning relationships [0.03%]
给吃牧草基础日粮的奶牛补充尿素以模拟氮分布的关系
S J Hendriks,N Lopez-Villalobos,A J Sheahan et al.
S J Hendriks et al.
The main objective of this study was to investigate whether altering dietary crude protein (CP) through the supplementation of urea to a basal pasture diet fed to dairy cows accurately modeled N-partitioning relationships. To test this, we ...
Human chorionic gonadotropin dose response for induction of ovulation 7 days after a synchronized ovulation in lactating Holstein cows [0.03%]

Our objective was to assess the effect of treatment with GnRH or 4 increasing doses of human chorionic gonadotropin (hCG) on the ovulatory response of a first-wave dominant follicle and subsequent plasma progesterone (P4) concentrations. La...
Selection and drift reduce genetic variation for milk yield in Manech Tête Rousse dairy sheep [0.03%]

Decreases in genetic variance over generations reduce future genetic gain. We studied the evolution of genetic variance in the dairy sheep breed Manech Tête Rousse, which has been selected for increasingly complex objectives, including, in...
Supercritical CO2 treatment reduces the antigenicity of buttermilk β-lactoglobulin and its inflammatory response in Caco-2 cells [0.03%]
超临界CO2处理降低乳清β-乳球蛋白的抗原性及其在Caco-2细胞中的炎性反应
Israel García-Cano,Po-Wei Yeh,Diana Rocha-Mendoza et al.
Israel García-Cano et al.
β-Lactoglobulin (β-LG) is believed to be a common allergen in bovine milk. Buttermilk (BM) powder has abundant contents of milk fat globule membrane and phospholipid, both of which have been demonstrated to have positive effects on brain ...
Evaluation of PEETER V1.0 urine sensors for measuring individual urination behavior of dairy cows [0.03%]
PEETER V1.0尿液传感器在测量奶牛个体排尿行为中的评估
C J Marshall,M R Beck,K Garrett et al.
C J Marshall et al.
Due to environmental concerns around N leaching and NO2 emissions from intensive pastoral dairying systems, there has been an increase in research focused on mitigation strategies and on-animal technologies to evaluate urination behavior of...
Effect of source and level of forage in the diet on in vitro ammonia emission from manure of Holstein and Jersey dairy cows [0.03%]
日粮中粗饲料来源和水平对荷斯坦奶牛和泽西奶牛粪便体外氨气排放的影响
M E Uddin,M A Wattiaux
M E Uddin
Reducing overall reactive N losses from dairy production systems depends substantially on reducing the atmospheric emission of manure ammonia (NH3). The objective of this study was to determine potential NH3-N emission of reconstituted manu...

Dairy products are considered a staple in the American diet due in part to their nutritious content and appealing flavor. Consumption patterns may differ among age segments influenced by preferences for fat content and taste in dairy. Furth...
Using microwave-accelerated digestion instead of dry ashing during sodium analysis of low-moisture, part-skim mozzarella [0.03%]
在低水分部分脱脂莫扎里拉奶酪的钠分析中使用微波加速消化代替干灰化技术

Mineral analysis of cheese products is a labor- and time-intensive process. Pretreatment using dry or atmospheric wet ashing to decompose organic matter before measurement on a spectrometer can take more than 24 h to complete. Samples of lo...
Genomic evaluations using data recorded on smallholder dairy farms in low- to middle-income countries [0.03%]
使用低收入和中等收入国家小农户奶牛场记录的数据进行基因组评估
Owen Powell,Raphael Mrode,R Chris Gaynor et al.
Owen Powell et al.
Breeding has increased genetic gain for dairy cattle in advanced economies but has had limited success in improving dairy cattle in low- to middle-income countries (LMIC). Genetic evaluations are a central component of delivering genetic ga...
Reducing computational cost of large-scale genomic evaluation by using indirect genomic prediction [0.03%]
通过使用间接基因组预测来降低大规模基因组评估的计算成本
S Tsuruta,D A L Lourenco,Y Masuda et al.
S Tsuruta et al.
Over half a million Holsteins are being genotyped annually in the United States. The computational cost of including all genotypes in single-step genomic (ssG)BLUP is high, although it is feasible to conduct large-scale genomic prediction u...
