Aim: The present study was carried out to evaluate the nutrient digestibility of sweet sorghum stover, an unconventional roughage source in ram lambs in comparison to conventional sorghum and maize stovers. Materials and Methods: 18 Nellore ram lambs aged about 3 months (average body weight 15.65±0.10 kg) were randomly allotted to three complete rations formulated with roughage to concentrate r...

Assessment of nutrient variability, feed value, ensiling capability, intake, and digestibility of grocery food waste recycled from large retail stores was conducted in 3 experiments. In Exp. 1, 115 proximate nutrient analyses of grocery byproduct feed (GBP) from stores in the southern United States from April 8, 2011, to November 18, 2012, were evaluated for variation in nutrient concentration....

Ryegrass is a highly nutritious grass that can be utilized for grazing or production of baleage, haylage, or hay. In contrast to many regions of the world that are suitable for production of perennial ryegrass, annual ryegrass varieties are best suited for use in the Southeast US. When properly managed, annual ryegrass provides moderate concentrations of degradable protein. Annual ryegrass is h...

The fixed metabolizable energy (ME) values from the NRC do not represent the true ME values of the various feedstuff used in livestock rations. Therefore, a rapid and effective method for evaluating the ME value of forage crops is required for proper ration formulation to improve production efficiency. Dairy goat digestion trials were conducted as the in vivo reference using the method of Menke...

background: affecting the female reproductive organ and the layers around the oocyst, some ration ions could facilitate the penetration of sperm with specific chromosome type and change the sex ratio in mammal infants. objectives: the purpose of the present study was to evaluate the effect of potassium supplement on the sex ratio in rat. methods: the percentage of moisture, ash, crude fat and p...

Exploring improved tropical forages is considered to be an important approach in delivering quality and consistent feed options for dairy cattle subtropical regions. The present study aimed the suitability of three grasses, Chloris gayana ‘Rhodes grass cv. Reclaimer’ (RR), Megathyrsus maximus ‘Gatton Panic’ (GP), Brachiaria ruziziensis x B. decumbens brizantha ‘Brachiaria Mulato II’ (BM) evalua...

The most important analytical measurements for evaluating hay crops are those that are used to establish economic value or to meet the nutritional requirements of the animals to which it is fed. The objectives of this review are to identify and discuss the most important analyses that are important for determining the economic and nutritional value of hays for dairy cows. It is proposed that th...

Since it started as an organized economic activity, poultry production has been undergoing an evolution toward the optimization of its feed formulation features. Notably, advances in the knowledge of birds' nutrient requirements have allowed recommendations that are increasingly closer to the needs of the birds. Over time, availability of nutrients and energy has been incorporated into those re...

two experiments were conducted to determine lysine (lys) requirements of two commercial strains, ross 308 and cobb 500, from 15 to 28d of age. basal diet was formulated to be adequate in all nutrients except for lys. incremental levels of supplemental lys were added to the basal diet generating six experimental treatments in a range from 0.60 to 1.20% digestible lys. birds were randomized acros...
