In vitro gas production, in situ digestibility, intake, weight gain and ruminal characteristics of calves fed a diet containing 60% waste papaya silage.

Our aim was to evaluate a whole-grain diet containing 0 (T1) and 60% (T2) waste papaya silage in vitro, in situ and in vivo. In vitro, biogas, methane and dry matter degradation (DMDiv), neutral detergent fiber (NDFDiv) and crude protein (CPDiv) were determined at 72 h; in situ, DM (DMDis), NDF (NDFis) and CP (CPDis) digestibility was determined at 72 h; in vivo, consumption and apparent digestibility of DM (DMI and DMD) and NDF (NDFI and NDFD), daily weight gain (DWG), rumen characteristics (pH, bacterial and protozoan counts) were determined. In addition, we performed coproparasitoscopic analysis and interviews with producers.

Analysis of the Intestinal and Faecal Bacterial Microbiota of the Cervidae Family Using Next-Generation Sequencing: A Review.

The Cervidae family has a wide distribution due to its adaptation to numerous ecological environments, which allows it to develop a diverse microbial community in its digestive tract. Recently, research has focused on the taxonomic composition and functionality of the intestinal and faecal microbiota of different cervid species worldwide, as well as their microbial diversity and variation under different associated factors such as age, sex, diet, distribution, and seasonal variation. In addition, there is special interest in knowing how cervids act as reservoirs of zoonotic pathogenic microorganisms, which represent a threat to public health.

Effect of waste mango silage on the gas production, digestibility, intake, apparent digestibility, and ruminal characteristics in calf diets.

Background And Aim: Mexico is the fifth largest producer of mangoes in the world. For the conservation of agro-industrial waste and crop residues, the ensiling technique has shown good results. This study aimed to evaluate the effect of increasing the level of mango silage (86% waste mango and 14% pangola grass hay) in calf diets on gas production, digestibility, intake, apparent digestibility, and ruminal characteristics.

Effect of parota (Enterolobium cyclocarpum) pod protein supplement on feed intake and digestibility and calf ruminal characteristics.

The objective of this study was to evaluate feed intake and digestibility and ruminal characteristics of development-stage calves fed mulatto II (Brachiaria sp.) grass hay (MGH) and a protein supplement (PS) consisting of increasing levels of the parota (Enterolobium cyclocarpum) pod (PP). We used eight Swiss-zebu calves in growth stage with an average age of 11 months and initial average weight of 157.

Inclusion of ripe mango as a source of energy in diets for Creole lambs in the dry tropics.

The aim of this investigation was to evaluate the use of ripe mango as a source of energy in an integral diet consisting of regional products for fattening lambs. Twenty-seven Creole lambs were used and given a 10-day period to adapt to the diet. Three treatments were evaluated: T1 = 40% mango; T2 = 50% mango; and T3 = control diet.
