“…At birth, the rumen-reticulum compartment of calves is not fully developed and is nonfunctional, corresponding to 30.0 % of the complex stomach; this is transient since the development of the digestive tract occurs as the calves grow (COSTA et al, 2003). The development of the rumen depends on the intake of solid diet and the consequent rate of short-chain fatty acids (SCFA) production.…”

Performance and development of gastric compartments of calves fed with cheese whey and transition milk

et al. 2019

This study aimed to evaluate whether cheese whey associated with transitional milk or not, could serve as a suitable alternative to whole milk for calf rearing. For this, twenty-four male calves of crossbred Holstein-Zebu, were distributed in a completely randomized design with three treatments (8 calves per treatment) and fed for 60 days with one of the following liquid diets: i) 100% whole milk, ii) 50% whole milk and 50% cheese whey, and iii) 30% transitional milk and 70% cheese whey. There was no difference in food intake between treatments. The analysis showed that whole milk replacement did not alter the stomach weight or the ruminal cell proliferation when compared to treatment using 100% whole milk; however, the transitional milk/cheese whey group showed larger ruminal papillae. These results suggested that a transitional milk-cheese whey diet associated with solid food and proper nutrient complements might enhance the post-natal development of rumen papillae in calves, which might contribute to prepare them for weaning.

“…Com a ingestão de volumosos e concentrados ocorre aumento na presença de ácidos graxos voláteis, que acelera o desenvolvimento das papilas ruminais, promovendo as mudanças anatômicas, fisiológicas e metabólicas no trato dos ruminantes jovens, podendo ser aceleradas ou retardadas, de acordo com o regime alimentar em que estão submetidos (Costa et al 2003).…”

RESUMO. O mercado da carne bovina no Brasil vem sofrendo grandes mudanças que afetam diretamente o produtor rural. Os mercados consumidores têm exigido produtos com melhor qualidade. Com isso, os sistemas de criação estão evoluindo para permitir que os animais sejam abatidos mais jovens e com pesos superiores. As propriedades rurais têm procurado se adequar a essa nova realidade, sendo que as propriedades que realizam a fase de cria do bezerro passam a ter grande importância para a cadeia produtiva da carne. Estas necessitam adotar novas técnicas que permitam o desmame de bezerros mais pesados e com maior uniformidade nos lotes, facilitando o trabalhado da fase seguinte, a recria. A utilização de uma dieta diferenciada e privativa no cocho para os bezerros na fase de lactentes é uma alternativa para alcançar o objetivo de produção de animais superiores à desmama.Palavras chave: cadeia produtiva, creep feeding, desmame, dieta Supplementation of nursing calves in private trough: ReviewABSTRACT. The beef market in Brazil has undergone great changes which directly affect the rural producer. Consumer markets have required products with best quality. Thereat, the systems of creation are evolving to allow the animals being slaughtered younger and with higher weights. The rural properties have wanted fit on this new reality, being that properties as perform calf creates phase they begin to have great importance on the supply chain meat. These need to adopt new techniques that allow the weaning of calves heaviest and greater uniformity on the batch, facilitating the working next phase, the rebuilds. The use of a differentiated and private diet there for the calves on the lactating phase it's an alternative to achieve the production goal of superior animals at weaning.

In the northeastern region of Brazil, sheep and goat farming, encompassing around 20 million animals, is predominantly a subsistence activity. Forage quality plays a crucial role in animal productivity, posing a complex interplay between plant and animal aspects. The Caatinga biome, vital for livestock in the region, serves as a significant source for animal diet through pastures. This study aimed to conduct a histomorphometric evaluation of sheep rumens in a semi‐extensive system, comparing those feeding on native Caatinga pastures to those on cultivated pastures. Histological processing followed standard protocols, with morphometry focusing on six viable rumen papillae and the submucosa and muscular layer thickness. Statistical correlation analysis revealed morphological differences in papillae across various rumen regions. Morphometric data indicated no significant difference in papillae area between the groups, with average values in Group A surpassing those in Group B, except for width. This study establishes a morphological and morphometric pattern for rumen regions linked to diet types—native or cultivated. The findings not only enhance understanding of the dietary foundation in the Caatinga's extensive system, but also contribute valuable insights for formulating nutritional strategies to enhance sheep production in the region. This research sheds light on the intricacies of forage‐based animal nutrition, particularly in semi‐extensive systems, offering a foundation for future studies and practices to optimise livestock management in the northeastern Brazilian context.
