The microbiome of the digestive tract of ruminants contains microbial ecosystem that is affected by both environmental and genetic factors. The subject of this study concerns the influence of selected genetic factors, such as species of animals and “host” individual differences on the digestive tract microbiome composition.

Good quality protein as an on-farm feed resource has been in great demand to support the productivity of ruminants. A digestion trial using beef cattle crossbreds was conducted to assess the four dietary treatments of Flemingia macrophylla silage (FMS) supplementation at 0, 0.2, 0.4 and 0.6 kg dry matter (DM)/day in a 4 × 4 Latin square design.

Ruminants are an important part of world animal production. The main factors affecting their production rates are age, diet, physiological condition and welfare. Disorders related to low level of welfare can significantly affect the microbiological composition of the digestive system, which is essential to maintain high production rates.

The transition from a high forage to a highly fermentable diet can induce digestive disorders in the rumen. To date, the host mechanisms that regulate the adaption to such dietary transition are largely unknown. To understand the molecular mechanisms involved in such phenomena, RNA-sequencing was performed to identify the changes in the transcriptome of ruminal epithelia during gradual transition from a diet containing 0% to 89% grain.

Continuous efforts are being made to utilize the fibre feeds to the maximum extent in ruminants which form a staple feed in tropical countries. Though only about 65% of the fibre is effectively digested in the rumen, need to supplement certain exogenous fibrolytic enzymes (EFE) has become mandatory. The main principle with which EFE is added is to specifically target the increased bacterial multiplication of certain species which enhances rumen degradation of cellulose which constitutes the major part of the forages.

In the first two chambers, the food is mixed with saliva and separates into layers of solid and liquid material. Solids clump together to form the cud or bolus.

This experiment was based on the hypothesis that whether use of exogenous enzymes in ruminant diets is beneficial for feed digestion and improving animal productivity or not. For this study, total 20 cows and 20 buffaloes were selected and divided into four groups namely A, B, C and D. The trial was conducted on Private Dairy farm of Rajnandgaon District, Chhattisgarh, India where pre and post feeding effect of Hostazyme (Xylanase) was studied. The above study recommended the use of Hostazyme at 5 g per day in cows and 10 g per day in buffaloes for economic milk production.

Sub-acute ruminal acidosis (SARA) is a significant production digestive disorder of dairy cattle. This study conducted a point prevalence study of rumen health status in well-organized dairy herds in pollachi district of Tamil nadu. The study assessed rumen fluid, animal health status, milk production data and biological parameters. A total of sixty cows in early to mid-lactation were sampled from three farms. 8.33 percent of dairy cows managed under semi-intensive system were tested positive for SARA.

The bacteria in ruminant animals help to digest the food and produce copious amounts of carbon dioxide and methane in the process. So, to know the effect of feed on CO2 emission from rumen of he-buffalo the study was conducted at 4 different feed concentration at two different draught levels at 3 hour of exercise on treadmill having speed of 2 km/h and 3 hour of rest period under maintained environment controlled chamber. The environment temperature and relative humidity was maintained according to the average temperature and relative humidity of the area which was 25oC and 90%.

Theoretical training starts with an explanation of the digestive system of ruminants and how ruminant animals are different from non-ruminants. Diagrammes of the diges- tive system of ruminants in power-point slides as well as video clips on the digestion and absorption of different nutrients is also shown during the training. The session on animal feeding includes name, identification, class of feed, major sources of nutrients, i.e. energy and protein, dry matter content, palatability, digestibility, intake etc.

Animals fed on concentrate-rich diets ( 60%), may go off-feed due to ruminal acidosis. A low pH is detrimental to the rumen fibre digesting bacteria which may cause a depression in fat content in the milk. It can also affect the animal’s health status. In such cases, use of a buffer is rec- ommended comprising sodium bi-carbonate and magnesium oxide (3:1) to be fed @ 50–75 g per animal per day. Alternatively it is possible to introduce some longer physical fibre into the ration (e.g. paddy straw) to promote rumination and saliva production.
