“…The improvement in body weights, BWG, and ADG and the worseness in the feed to gain ratios after supplementation with organic acids (formic acid) has been seen in this study are in agreement with those reported previously (33,34). The first authors found feed intake to decrease and consequently, improvement feed conversion with the supplementation of diet with citric acid from 0.5% and up to 2.0% whereas, the second author recorded improvement of body weight gains with 0.5% fumeric, citric, and malic acids.…”

The aim of present study was to examine the effect dietary supplementation of formic acid on growth performance, some heamatological, biochemical and oxidative stress parameters as well as carcass traits of summer stressed Californian (CAL) and Californian × Rex (CAL × RX) crossbred rabbits. A total of 60 rabbits 4 weeks old were allotted into 2 × 3 completely randomized design (two genotypes; CAL and CAL × RX and three dietary treatment; 0, 0.3 and 0.5% formic acid).Rabbits were subjected to a temperature of 32±1°C during the experimental period, they were slaughtered at 10 weeks of age and blood samples were collected at slaughtering. Rabbits fed diet with 0.5% formic acid had the higher final body weight (P<0.001), body weight gain (BWG) (P<0.001), average daily gain (ADG) (P<0.001) and the lowest feed to gain ratio (P<0.001) compared with those fed diet with 0.3% formic acid and the control rabbits. Rabbits fed diet supplemented with 0.3% formic acid had higher significant total protein (P<0.001) and globulin (P<0.001) than the control rabbits whilst, the highest significant red blood cell (RBCs), white blood cell (WBCs) count and catalase activity have been recorded in 0.5% formic acid group. Carcass traits significantly affected (P<0.05) by dietary supplementation of formic acid were; hot and reference carcass weights, and dressing-out, skin, stomach, intestine, liver, hind part proportions. The effect of genotype × dietary supplement of formic acid was significant for average daily feed intake (ADFI), (P=0.028), cholesterol (P=0.001), Hb (P=0.002), haematocrit percentage (P=0.006) glutathione peroxidase (P=0.026), and dressing-out% (P=0.028). Net profit for CAL and CAL × RX were 8.68 and 10.34 (LE/rabbit) and for 0, 0.3 and 0.5% formic acid were 4.87, 10.11 and 13.72 LE/rabbit. In conclusion, Formic acid can be used as a dietary supplement at 0.5% of diet to improve economic efficiency, growth traits and health, immune parameters in the blood and improved the antioxidant status without any harmful effect on carcass traits.

“…Maertens; Berchiche (2016) e Scapinello et al (2011) apresentaram nos seus trabalhos consumos médios diários sem especificar o consumo de silagem provavelmente porque não ofereceram silagem à vontade aos animais ou não controlaram o consumo de silagem em separado.…”

“…A silagem é a forragem conservada pelo processo de fermentação anaeróbica e segundo Teixeira, Amin e Mello (2009), o milho é a espécie forrageira mais utilizada para ensilagem devido à sua boa qualidade nutricional, aceitação pelos animais e produção de massa seca por hectare. A silagem de grão úmido de milho (SCAPINELLO et al, 2011), a silagem de milho de planta inteira (GUERMAH;MAERTENS;BERCHICHE et al 2016) e a planta inteira de milho desidratada (MARTÍNEZ et al, 2006) foram eficazes na alimentação de coelhos em crescimento, porém continuam necessários mais estudos para maximizar a inclusão na alimentação dos animais. O girassol também pode ser ensilado e utilizado na dieta animal, porém ainda são escassas as informações da utilização de girassol na dieta de coelhos.…”

É provável que, por tratar-se de uma ração comercial, a dieta basal utilizada no presente experimento animal (alta em energia bruta e baixa em fibra bruta) não atendeu às exigências da categoria, fenômeno que já foi verificado porMachado et al…”

Os coelhos têm capacidade de aproveitar parte das fibras devido ao processo fermentativo cecal e hábito da cecotrofia. Nesse sentido, uso de forrageiras conservadas como complemento alimentar é uma alternativa na criação visto que a ração comercial é o insumo mais oneroso na cunicultura. O objetivo deste trabalho foi avaliar o uso de silagem de girassol ou silagem de milho na alimentação de coelhos em crescimento sobre desempenho e viabilidade econômica da dieta. Utilizou-se 15 animais de ambos os sexos, com 45 dias, distribuídos em 3 tratamentos e cinco repetições cada, durante 69 dias. Os tratamentos avaliados foram: dieta basal (DB), dieta basal e silagem de girassol (SG) e dieta basal e silagem de milho (SM). Animais alimentados com SM consumiram 20% menos ração que animais consumindo DB. O consumo de silagem diário foi diferente entre os tipos de silagem fornecida. O consumo de água foi menor nos animais alimentados com silagem. O ganho médio diário não diferiu, sendo de 33 g, 38 g, e 34 g respectivamente para os animais alimentados com DB, SG e SM. Ocorreu redução no custo da alimentação utilizando silagem na dieta de coelhos. Os coelhos que foram alimentados com SM apresentaram melhor viabilidade econômica.

“…Studies related to animal feed have discussed the care needed to ensure the quality and safety of the product (SANTIN, 2006), evaluate the losses (the quantity, costs and contaminations of the products) caused by the equipment maintenance in different stages of a feed production mill (CORADI et al, 2015). Predominately there are also studies related to diet formulation for different animals (SCAPINELLO et al, 2011;ZANGERONIMO et al, 2009). However, up to now, few studies were focused on workplace safety conditions for the workers, in units of animal feed mills (CARVALHO et al, 2008;SILVA et al, 2011).…”

Were analyzed the working conditions in a small feed mill, with identification of occupational risks (physical, chemical, biological, ergonomic and accidents) and measurement of noise levels. Data collection was performed qualitatively by using a survey, previously developed, as well as in loco observation. There was at least one factor belonging to the five occupational risks, and the ergonomic risk was associated with all activities. The feed mill assessed was not in accordance with the Regulatory Standards related to Health and Safety, and arrangements to adjust it accordingly must be taken. Corrective actions goes from the purchase and supply of appropriate personal protective equipment for worker to structural changes, such as installing handrails and repairing of electrical installations. These initiatives, if implemented could contribute to reducing the risks that affect the health and physical integrity, with opportunities to improve quality and productivity of the services performed.
