Interaction between residual feed intake and thermal environment on performance, nitrogen balance, ingestive behavior and carcass yield of dorper lambs.

Residual feed intake (RFI) is a nutritional variable used in genetic improvement programs, the relationship between the environment and the availability of energy and protein in the diet has not yet been explored. Thus, the aim was to evaluate interactions between RFI and thermal environment on performance, nitrogen balance, ingestive behavior and carcass yield of Dorper lambs receiving diets containing different concentrate levels. Dorper lambs (male, n = 64, 17.

An Overview of the Occurrence of Bioactive Peptides in Different Types of Cheeses.

The search for improvements in quality of life has increasingly involved changes in the diet, especially the consumption of foods which, in addition to having good nutritional value, are characterized by offering health benefits. Among the molecules that trigger several beneficial responses are peptides, which are specific fragments of proteins known to produce positive effects on the human body. This review aimed to discuss the bioactive potential of peptides from cheeses.

Asinine milk mitigates stress-mediated immune, cortisol and behavioral responses of piglets to weaning: A study to foster future interventions in humans.

Introduction: The present study assessed whether asinine milk supplementation improved the immune and behavioral responses of piglets during an early life weaning stress event as a model for its future use in humans.

Methods: For this, 48 piglets from 4 different litters were used. At 20 days of age, piglets were weighed and allocated with their litter and dam into group pens until 28 days of age.

Dietary Effect of Palm Kernel Oil Inclusion in Feeding Finishing Lambs on Meat Quality.

This study evaluated the effects of palm kernel oil (PKO) in the diet of lambs on carcass characteristics, quality, and fatty acid profile of the meat. Forty uncastrated male Santa Inês lambs were used and divided among the treatments: PKOzero without inclusion; PKO1.3—added 1.

Innovation in Alternative Food Sources: A Review of a Technological State-of-the-Art of Insects in Food Products.

Insects present great potential for the food industry due to their easier rearing conditions and high nutritional value, in comparison with traditional livestock. However, there is a lack of evaluation of the technological status of food products developed with edible insects. Therefore, this study aims to analyze the emergent technological and scientific applications of edible insects in the food industry through a prospective study of patent documents and research articles.

Utilization of Agro-Industrial Residues in the Rearing and Nutritional Enrichment of Larvae: New Food Raw Materials.

Edible insects are a potential alternative food source of high feed conversion efficiency and protein content. is an edible insect that adapts to different diets, enabling sustainable rearing by adding value to by-products and agro-industrial residues. This study aimed to evaluate the performance and nutritional characterization of larvae fed with different proportions of grape residue.

Effects of Increasing Levels of Palm Kernel Oil in the Feed of Finishing Lambs.

The aim of this study was to evaluate the effects of the inclusion of palm kernel oil (PKO) in a lamb diet on nutrient intake, digestibility, ingestive behavior, nitrogen balance, blood metabolites, rumen fermentation parameters, and animal performance. Three experimental trials were conducted. The treatments consisted of varying levels of PKO included in the diet, with PKO = no PKO inclusion, PKO = 1.

Physicochemical composition, fatty acid profile and sensory attributes of meat (longissimus lumborum muscle) from Nellore and Nellore-cross bulls.

This study aimed to compare the physicochemical characteristics, fatty acid composition, and sensory attributes of the meat from three genetic groups: Nellore (Nell), ½ Nellore × ½ Angus (NeAn), and ¼ Nellore × ¼ Angus × ½ Senepol (NASe). Longissimus lumborum muscle from 30 slaughtered bulls with a body weight of 549 ± 32.5 kg was used.

Intake, digestibility, nitrogen balance and performance of crossbreed Boer goats fed with diets containing saltbush (Atriplex nummularia L.) and spineless cactus (Opuntia ficus-indica).

Saltbush and spineless cactus are adapted to arid and semiarid regions and used as an important forage resource in ruminants' diet. However, spineless cactus restricts production due to its low crude protein and NDF levels and high salt and oxalate contents, which can limit the digestibility and intake of dietary nutrients. Therefore, this experiment was conducted to evaluate the best ratio levels of saltbush associated with spineless cactus in diets for crossbreed Boer goats through ingestion, water balance, digestibility, nitrogen balance, growth and carcass weight.

Digestion, ruminal metabolism, and feeding behavior of buffaloes fed diets supplemented with soybean oil, whole and raw soybean, and calcium salts of fatty acids.

This study aimed to evaluate the effects of the inclusion of unsaturated fatty acid (UFA) sources on the nutrient intake, apparent digestibility, ruminal fermentation, and feeding behavior in diets for buffaloes. Four castrated Murrah buffaloes with approximately 24 months of age and an initial average body weight of 351 ± 15 kg were randomly assigned to a 4 × 4 Latin square experiment, containing the following diets: (1) control (CON): control diet based on soybean meal and ground corn, (2) soybean oil (SO): dietary inclusion of 2.20% (DM basis), (3) whole raw soybean (WRS): dietary inclusion of 16.

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.

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

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.

Commercial cuts and chemical and sensory attributes of meat from crossbred Boer goats fed sunflower cake-based diets.

This study aimed to evaluate sunflower cake feed in commercial cut yields and chemical and sensory attributes of goat meat. Thirty-two castrated male goats were distributed in four levels (0, 8, 16 and 24%) of sunflower cake supplementation. The animals were slaughtered and the carcasses were placed in a cold chamber and sectioned into five anatomical regions corresponding to commercial cuts.

Effects of substituting soybean meal for sunflower cake in the diet on the growth and carcass traits of crossbred boer goat kids.

The present study was conducted to determine the best level of substitution of soybean meal by sunflower cake in diets for kids through the evaluation of quantitative carcass traits. Thirty-two Boer kids X 1/2 NDB (no defined breed), males, non-castrated, with 4 months of age and initial body weight of 15±3.2 kg, were randomly assigned to individual pens.
