13. Dorper sheep utilizing feed resources efficiently: a Mediterranean case study
ABSTRACT The aim of the study was to determine the effect varying feeding systems would have on meat quality and production. The study looked at 45 Dorper lambs which were subjected to three different feeding protocols representing three alternate production systems: extensive grazing system (Group G), an intensive feedlot system being fed concentrate + alfa

14. Effect of alfalfa hay on growth performance, carcass characteristics, and meat quality of growing lambs with ad libitum access to total mixed rations
ABSTRACT Forty male Naemi lambs were used to evaluate the effect of total mixed rations (TMR) alone or in combination with supplementation of alfalfa hay offered at different schedules on growth, carcass characteristics, and meat quality. Lambs at the age of three months, with an average weight of 28.85±1.09 kg, were randomly selected and distributed into f

16. Effects of heat stress on the physiological parameters and productivity of hair sheep in tropical and coastal environments
The experiment was carried out with sheep during the finishing phase in a partial confinement system to evaluate the following physiological parameters: rectal temperature (RT), respiratory rate (RR), heart rate (HR), productive performance and carcass characteristics. Fourteen uncastrated sheep with an average initial age of 90 days belonging to two genetic

17. Rendimento de grãos e características agronômicas de soja em função de pastagens perenes em sistema de plantio direto
O objetivo do presente estudo foi avaliar o desempenho de soja em sistemas de produção com integração lavoura-pecuária em plantio direto. Constituíram os tratamentos cinco sistemas de produção: sistema I (trigo/soja, ervilhaca/milho e aveia branca/soja); sistema II (trigo/soja, pastagem de aveia preta + ervilhaca/milho e aveia branca/soja); sistema I

18. Feed type for induced molting of commercial layer hens
An experiment employing three hundred and twenty 81-week-old Lohmann LSL commercial-breed hens was conducted to compare alternative induced-molting methods with the conventional method (fasting). Induced molting lasted 28 days at most, production and quality being monitored for four periods of 28 days thereafter. A completely randomized experimental design w

19. Dietary fiber inclusion as an alternative to Feed Fasting to induce molting in Commercial Layers
The objective of the present experiment was to compare the performance, egg quality and organ morphometrics of commercial layers submitted to alternative forced molting methods using dietary fibers. The experimental period included the phases of molting, rest, and second laying cycle (six periods of 28 days each). In the trial, 320 commercial Isa Brown layer

20. Effect of forced-molting methods and rearing temperatures on the performance and organ biometrics of laying hens
An experiment was conducted to evaluate the biometrics of organs (ovary, oviduct, liver, proventriculus and gizzard) of laying hens submitted to different forced-molting methods of molt and maintained at three different temperature. Organs were evaluated after molting and resting period. Six hundred birds were distributed according to a completely randomized

21. Artificial neural networks for adaptability and stability evaluation in alfalfa genotypes
The purpose of this work was to evaluate a methodology of adaptability and phenotypic stability of alfalfa genotypes based on the training of an artificial neural network considering the methodology of Eberhart and Russell. Data from an experiment on dry matter production of 92 alfalfa genotypes (Medicago sativa L.) were used. The experimental design constit

22. El cultivo de alfalfa utilizando agua de perforación, agua residual urbana y precipitaciones
The objective of this study was to analyse the production of alfalfa biomass, the efficiency of water use and the nutritional value of forage, inside an irrigation structure of an experimental facility that uses treated urban wastewater, artesian well water and rainfall, at the campus of the Universidad National de Rio Cuarto (Córdoba-Argentina). The irriga

23. Apparent digestibility of simplified and semi-simplified diets, with and without addition of enzymes, and nutritional value of fibrous sources for rabbits
The objectives of this study were to evaluate the digestibility of the nutrients of simplified and semi-simplified diets, with and without inclusion of exogenous enzymes and to determine the nutritional value of the fibrous sources. The tested feedstuffs were: alfalfa hay, hay from the upper third of the cassava foliage and cassava leaf meal, using a complet

24. Roughage digestion evaluation in horses with total feces collection and mobile nylon bags
This study aimed to evaluate the nutrient digestibility of roughages in horses with total feces collection and mobile bags. Two trials were carried out simultaneously. The first trial evaluated the digestibility of nutrients of coastcross hay (Cynodon dactylon cv. coastcross) with total feces collection. The second trial assessed the digestibility of nutrien
