Properties of conventional and alternative bedding materials for dairy cattle.

open access: yesJournal of Dairy Science, 2020
The bedding material used in barns for dairy cows has a significant effect on animal welfare and performance. Bedding influences the duration in which animals remain lying down and, consequently, the processes of rumination and milk production.

Estimation of 305-day milk yield from test-day records of Chinese Holstein cattle

open access: yesJournal of Applied Animal Research, 2018
This study compared six models, namely the Gaines, Sikka, Nelder, Wood, Dhanoa and Hayashi models, for the estimation of 305 days milk yield in Chinese Holstein cattle. We compared their ability to reliably predict 305-day lactation yield from incomplete

Nutritional Physiology and Biochemistry of Dairy Cattle under the Influence of Heat Stress: Consequences and Opportunities

open access: yesAnimals, 2020
Simple Summary Modern dairy cows have elevated internal heat loads caused by high milk production, and the effects of accumulating incremental heat are exacerbated when temperature and humidity increases in the surroundings. To shed this additional heat,

Influence of Diet on Methane and Nitrous Oxide Emissions from Cattle Manure

open access: yesAsian Journal of Atmospheric Environment, 2015
Livestock is one of the major contributors of greenhouse gases (GHGs). It accounts for 14.5% of the global GHGs emissions like methane (CH4) from enteric fermentation and manure, nitrous oxide (N2O) from manure and fertilizer. Since enteric emissions are

Longevity in Dairy Cattle [PDF]

open access: yesAdvances in Dairy Research, 2014
Longevity of productive life in dairy cattle is a characteristic difficult to evaluate. This measurement is complicated, in part, because the phenotype is expressed late in the life of the animal, but also because the methods of evaluation are complex. The molecular bases of longevity are still far from being fully understood, although some genes begin

Plasma hormones and milk production performances in early lactation buffaloes supplemented with a mixture of prilled fat, sweetener and toxin binder [PDF]

open access: yesBiotechnology in Animal Husbandry, 2016
The effect of combined feed supplements (prilled fat, sweetener and toxin binder) was studied on 24 apparently healthy early lactating rural and urban maintained Murrah buffaloes. The feeding of combined feed supplement was carried out for a period of 90

Polyunsaturated Fatty Acids in Male Ruminant Reproduction — A Review [PDF]

open access: yesAsian-Australasian Journal of Animal Sciences, 2017
Fatty acids such as n-3 and n-6 polyunsaturated fatty acids (PUFA) are critical nutrients, used to improve male reproductive performance through modification of fatty acid profile and maintenance of sperm membrane integrity, especially under cold shock ...

Net benefits of smallholder dairy cattle farms in Senegal can be significantly increased through the use of better dairy cattle breeds and improved management practices.

open access: yesJournal of Dairy Science, 2020
Senegal, located in West Africa, is an example of a low- to middle-income country where the government has prioritized improving livestock production self-sufficiency, with a strong focus on dairy.
