Effect of Pelagic on In Vitro Dry Matter and Organic Matter Degradation, Gas Production, and Protozoa Population.

This study determined the effect of pelagic on in vitro dry matter and organic matter degradation, total gas production (TGP), and protozoa population. The treatments were different levels of inclusion on a basal substrate (Stargrass hay; ) as follows: T0 (control treatment based on Stargrass hay), T10 (90% Stargrass hay + 10% ), T20 (80% Stargrass hay + 20% ), and T30 (70% Stargrass hay + 30% ). Ruminal fermentation kinetics and protozoa population were determined during 72 h of in vitro incubations.

Using plant-based compounds as preservatives for meat products: A review.

The susceptibility of meat and meat products (MP) to oxidation and microbial deterioration poses a risk to the nutritional quality, safety, and shelf life of the product. This analysis provides a brief overview of how bioactive compounds (BC) impact meat and MP preservation, and how they can be utilized for preservation purposes. The use of BC, particularly plant-based antioxidants, can reduce the rate of auto-oxidation and microbial growth, thereby extending the shelf life of MP.

Residual Feed Intake and Rumen Metabolism in Growing Pelibuey Sheep.

This study was carried out to evaluate the residual feed intake (RFI), volatile fatty acid (VFA) production and enteric methane (CH4) from growing Pelibuey sheep. In this case, 12 non-castrated Pelibuey with an initial average live weight (LW) of 21.17 ± 3.

Effect of Chitosan and Naringin on Enteric Methane Emissions in Crossbred Heifers Fed Tropical Grass.

In order to meet consumer needs, the livestock industry is increasingly seeking natural feed additives with the ability to improve the efficiency of nutrient utilization, alternatives to antibiotics, and mitigate methane emissions in ruminants. Chitosan (CHI) is a polysaccharide with antimicrobial capability against protozoa and Gram-positive and -negative bacteria, fungi, and yeasts while naringin (NA) is a flavonoid with antimicrobial and antioxidant properties. First, an in vitro gas production experiment was performed adding 0, 1.

Effect of Feeding Lactating Ewes with Leaf Extract on Milk Yield, Milk Composition and Preweaning Performance of Ewe/Lamb Pair.

The objective this study was to evaluate the effect of different doses of leaf extract (MOE) on milk production and milk composition in ewes and on preweaning performance of their lambs. Twenty-four lactating ewes were housed individually with their lambs and assigned to four groups in a completely randomized design. The treatments included a basal diet without MOE (MOE0) or a basal diet supplemented with either 20 mL MOE per ewe per day (MOE20), 40 mL MOE per ewe per day (MOE40) or 60 mL MOE per ewe per day (MOE60).

Dry matter intake and digestibility of rations replacing concentrates with graded levels of Enterolobium cyclocarpum in Pelibuey lambs.

The aim of the study was to evaluate the effect of graded levels of Enterolobium cyclocarpum pods in the ration on feed intake and digestibility by Pelibuey lambs. Five dietary treatments were imposed where ground pods replaced concentrate diet at 0, 20, 30, 40 and 50 % of dry matter (DM), respectively. The concentrate portion was composed of ground sorghum, soybean meal, cane molasses and minerals.
