The objective of this work was to evaluate the nutritional parameters of young bulls supplemented with different ratios of protein: carbohydrate on tropical pastures from 4 until 18 months old. Fifty-five non-castrated beef calves (138.3±3.4 kg, 90 to 150 d of age) were used. The calves (young bulls) were subjected to a 430-d experimental period encompassing 4 seasons. The treatments were as fo...

Land degradation and poverty caused by traditional arable agriculture have been serious problems in the ecologically fragile and economically backward mountains of Nepal. There is a prospect to address both of these problems to some extent by promoting livestock raising. However, a large livestock population exceeding the carrying capacity of land resources will risk undermining the sustainabil...

Twenty eight Ossimi new born male lambs, with an average live body weight 4.75 kg and 7 days age were randomly assigned to two feeding groups each of 14 animals to study the effect of pre-weaning diet on lamb's performance. Both the two groups suckled their dams until being weaned at 12 weeks of age (natural weaning). The first group depended completely on dams milk as a solely available feed (...

Arlene Chua, Nathan Ford, David Wilson, Paul Cawthorne Two recent articles in PLoS Medicine [1,2] criticise the role played by activists in raising concerns about the tenofovir trial for HIV prophylaxis. We fully support the fact that activism should be based on informed opinion, rather than speculation, unwarranted criticism, overreaction, or sensationalising facts [1], and believe that in Tha...

Soil organic matter (SOM) is essential for sustaining soil health and crop productivity. However, changes in SOM stocks in response to agronomic practices are slow and show years later when it is too late for adjustments in management. Identifying early indicators of SOM dynamics will allow early management decisions and quick remedial action. The objectives of this study were to evaluate long-...

The objective of the study was to determine effect cassava pomace and protected soybean meal on dairy milk production quality mid lactating cows. This research conducted at Turen, Malang from January April 2020. Twelve Friesian Holstein cows were divided into 2 groups so that each group consisted 6, namely control treatment groups. feed a combination forage concentrate with ratio 35:65 in dry m...

Twenty eight lactating buffaloes were used in a completely randomized design with 2×2 factorial arrangement of four experimental diets including low protein–low energy (LP-LE), low protein–high energy (LP-HE), high protein–low energy (HP-LE) and high protein–high energy (HP-HE). Results showed that the HP-HE diet recorded the highest digestibility coefficients of CP, EE, NFE, nutritive values, ...

and rate of DNA synthesis in the mammalian cell, the intracellular production of thymidine (Tdn) nucleotides has received some attention and has been discussed in a recent review article by O'Brien (31). Increased activity of the enzymes related to the production of Tdr nucleo tides and their incorporation into DNA has been shown to occur in regenerating rat liver (3, 4, 5, 9, 25) as well as in...
