Cottonseed Cake as an Additive in BRS Capiaçu Grass Silage: Impacts on the Fermentative, Chemical, and Digestibility Characteristics of the Silages

New Zealand Journal of Agricultural Research, Volume 69, Issue 4, August 2026.
One of the major challenges in livestock production in the semiarid region of Brazil is the scarcity of water and feed for animals. In this context, the valorization of adapted forage crops associated with by‐products generated in the agro‐industry can contribute to circular agriculture, reduce waste, and promote more efficient use of natural resources,

The Efficacy of Food‐Grade Substances to Protect Dietary Glutamine From Ruminal Degradation

Journal of Animal Physiology and Animal Nutrition, Volume 110, Issue 4, Page 440-452, July 2026.
ABSTRACT This study was conducted to investigate the use of four, low cost, food‐grade substances to protect glutamine from microbial degradation in vitro, and subsequently validate their efficacy in vivo. Two in vitro trials were conducted using 250 mL bottles replicated in triplicate to test beeswax‐, paraffin wax‐, zein‐, and rice bran wax ...

Digestão dos nutrientes e balanço de compostos nitrogenados em cabras alimentadas com quatro níveis de proteína Digestion of the nutrients and nitrogen compounds balance in goats fed with different levels of protein

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2008
Avaliaram-se o consumo de alimentos, o pH e a concentração ruminal de amônia em quatro cabras, nas quais se coletou digesta de omaso via fistula ruminal para estimativa da digestão ruminal dos nutrientes.

Effects of Cottonseed Cake and Weissella cibaria on Fractionation of Carbohydrates and Proteins and In Situ Degradability in Sorghum Silages

New Zealand Journal of Agricultural Research, Volume 69, Issue 3, June 2026.
This study aimed to estimate the fractionation of carbohydrates and crude protein (CP), and the ruminal degradation rates of dry matter (DM), CP, and neutral detergent fiber (NDF) in sorghum silages. Silages were prepared with or without the addition of 10% cottonseed cake (CSC, natural matter basis) and Weissella cibaria (W. cibaria).

Effects of sodium chloride intake on urea-N recycling and renal urea-N kinetics in lactating Holstein cows

Journal of Dairy Science
: The effects of high (2.5% of DM) versus normal dietary sodium chloride (NaCl) intake on renal urea-N kinetics and urea-N metabolism were investigated in 9 rumen-cannulated and multicatheterized lactating dairy cows in a crossover design with 21-d ...

Concentration and composition of condensed tannins in leaves from fodder trees and shrubs in Pakistan

JSFA reports, Volume 6, Issue 6, Page 212-219, June 2026.
Abstract Background The lack of dependable, high‐quality forage and animal feedstuffs in many areas of the world hampers livestock production. In these regions, farmers often rely on native fodder tree and shrub leaves as a forage source for their animals with little or no information available on nutritional factors of these feedstuffs.

Overview of Encapsulated Lysine and Methionine and Their Impacts on Transition Cow Performance and Health

Animal Research and One Health, Volume 4, Issue 2, Page 145-166, May 2026.
The transition period in dairy cows, spanning 3 weeks before and after calving, is a critical phase characterized by increased nutrient demands, reduced dry matter intake (DMI), and elevated risk of metabolic disorders such as negative nutrient balance (NNB), lipolysis, proteolysis, and oxidative stress.

Comparison of Two Sampling Techniques for Evaluating Ruminal Fermentation and Microbiota in the Planktonic Phase of Rumen Digesta in Dairy Cows

Frontiers in Microbiology, 2020
The objective of this experiment was to compare ruminal fluid samples collected through rumen cannula (RC) or using an oral stomach tube (ST) for measurement of ruminal fermentation and microbiota variables.

Fermentation techniques for protein enrichment of cassava peel

Journal of the Science of Food and Agriculture, Volume 106, Issue 7, Page 4384-4393, May 2026.
Abstract BACKGROUND The use of agro‐industrial by‐products such as unconventional feeds in animal production is an alternative for reducing the high costs associated with conventional feeds. The present study aimed to evaluate the effect of aeration, pH adjustment, the use of yeast (Saccharomyces cerevisiae) and the amount of urea on the enrichment of ...
