Abstract The objective of this study was to prepare three donkey milk yoghurt formulations mixed with goat, cow and buffalo milk. The formulations were developed with 50% donkey milk and 50% cow, buffalo or goat milk. Concentrated mango pulp was added for flavouring. An evaluation was performed on the chemical composition of each milk sample and the formulated yoghurts. The donkey milk showed the lowest values for fat, protein, casein, total solids and non-fat solids. In turn, goat milk reached higher levels of fat and total solids. Furthermore, buffalo milk stood out with the highest values of protein and non-fat solids. Yoghurt made with donkey and buffalo milk showed higher concentrations of protein, lactose, total solids and non-fat solids. In contrast, the yoghurt that contained donkey and cow milk in its formulation obtained a higher fat percentage and a lower percentage of lactose, total solids and non-fat solids. The low content of fat and total solids in donkey milk, in addition to the structure of the casein micelles and small fat globules favor low consistency in fermented products. Thus, mixing donkey milk with milks from other animal species can result in better chemical composition and better consistency.

ABSTRACT The purpose of this study was to evaluate the effects of qualitative dietary restriction diet on carcass characteristics, meat quality, fatty acid profile, and performance of finishing pigs fed diets containing cashew bagasse bran. Forty pigs (20 females and 20 males) with initial weight of 60.00±5.24 kg of body weight (BW) were used. The diets were formulated with corn, soybean meal, cashew bagasse bran, vegetable oil, and mineral and vitamin mixture for finishing pigs. The experimental design was in randomized blocks with five treatments and four replicates, with two animals per experimental unit, one of each sex. Parameters related to performance, carcass characteristics, meat quality, and fatty acids profiles were used. The treatments used in the experiment did not affect feed intake and daily weight gain; however, in relation to feed conversion, a linear effect was observed with the increase of cashew bagasse bran levels in the diet. The same effects were also observed in carcass yield, backfat thickness, and fat area. The meat:fat ratio increased linearly with the increase of fiber in the diet. The level of 22.5% of cashew bagasse bran in finishing pig diets is recommended.

Abstract This literature review discusses the concepts and factors that influence industrial cheese yield and compiles the latest studies conducted in Brazil involving this theme. In seeking to support managerial decision-making, cheese yield can be measured at the end of processing or estimated prior to this. In research and industry, measuring and estimating yield can be evaluated under the effect of processing, from different proportions and characteristics of ingredients (mainly milk quality), to processing factors involving the steps of the actual production (handling of the raw material and the curd coagulation conditions, salting, maturation, etc.) and the equipment. The number of Brazilian studies that have sought to answer questions about this topic in recent years was reasonable. The vast majority of them considered yield in its most basic aspect, which is obtained by measuring what was produced. Few studies used the perspective of prediction, indicating that there is room for a more empirical approach that allows for obtaining other types of answers regarding efficiency in the production of cheese, and which is shown as an opportunity for Brazilian research to advance.
