New Technology of Rumen-Protected Bypass Lysine Encapsulated in Lipid Matrix of Beeswax and Carnauba Wax and Natural Tannin Blended for Ruminant Diets.

Tannins are compounds present in forage plants that, in small quantities in the diet of ruminants, produce protein complexes that promote passage through the rumen and use in the intestine. This study tested the hypothesis that beeswax (BW) and carnauba wax (CW) lipid matrices are effective encapsulants for creating bypass lysine (Lys) for ruminants, with tannin extracted from the hay source enhancing material protection. Microencapsulated systems were made using the fusion-emulsification technique with a 2:1 shell-to-core ratio and four tannin levels (0%, 1%, 2%; 3%).

Degradability, in vitro fermentation parameters, and kinetic degradation of diets with increasing levels of forage and chitosan.

Chitosan is the second most important natural biopolymer in the world, extracted from crustaceans, shrimps, and crabs and can modulate rumen fermentation. Our hypothesis is that the addition of chitosan alters the fermentation patterns of different diets for ruminants. This study aimed to evaluate the effects of different levels of chitosan and forage on in vitro dry degradation kinetics and fermentation in a gas production system.

Days in milk alters the milk fatty acid profile of grazing donkeys: A preliminary study.

The aim of this study was to characterize and determine how days in milk (DIM) affect the milk fatty acid (FA) profile of grazing donkeys. Donkey milk is very similar to human milk, containing bioactive molecules such as FA and proteins. However, there is a lack of scientific and technical information on the changes in the FA profile of asinine milk in pasture-feeding systems.

Fatty acid profile, physicochemical composition and sensorial attributes of salted and sun-dried meat from young Nellore bulls supplemented with condensed tannins.

The objective of this study was to evaluate the effect of condensed tannin inclusion (0, 10, 30 or 50 g/kg of dry matter (DM) total) from Acacia mearnsii extract on the fatty acid profile, physicochemical quality and sensorial analysis of salted and sun-dried meat from young Nellore bulls. The inclusion of condensed tannin extract in the young bulls' diets promoted a quadratic reduction in the lipid content. There was a linear increase in the water retention capacity, cooking weight loss and C18:3n-3 and a linear reduction in collagen, C16:0, C16:1cis-9, C18:1, MUFAs, and Δ9-desaturaseC18 in the salted and sun-dried meat from young Nellore bulls supplemented with condensed tannin.

Carnauba wax as a wall material for urea microencapsulation.

Background: The high ureolytic activity of rumen microbiota is a concern when urea is used in ruminant feed, because it leads to fast urea conversion, resulting in possible intoxication and lower nitrogen utilization. This study intended to microencapsulate urea using carnauba wax to obtain slow-release systems in the rumen. The experiment was conducted in a randomized block design, arranged in a 3 × 2 factorial, with the urea encapsulated with carnauba wax in ratios of 1 : 2; 1 : 3, and 1 : 4 (U 2; U 3, and U 4) and two particles sizes (small, P ; and large, P ).

Peanut cake can replace soybean meal in supplements for lactating cows without affecting production.

This study evaluated the total replacement of soybean meal with peanut cake in the concentrate supplement of lactating cows grazing. Eight crossbred 5/8 Holstein × 3/8 Zebu cows between the 45th and 60th day of lactation and 507 ± 35 kg BW were distributed in a 4 × 4 double Latin square design with four levels of peanut cake (0, 110, 220, and 330 g/kg of the dry matter-DM) as a replacement of soybean meal in the concentrate supplement. The intake of pasture, total (pasture + concentrate), crude protein (CP), neutral detergent fiber (NDF), total digestible nutrients, and digestibility of the DM, CP, ether extract (EE), and NDF was not affected by the replacement of soybean meal with peanut cake.
