Efficient utilization of Macadamia oil cake based diets in ruminants
… interdependent relationship loses energy and protein. Strategic feeding of ruminants with diets containing non-conventional feedstuffs appears to be a promising way to enhance proficiency of protein and energy utilization in ruminants. Macadamia Oil Cake (MOC) can be classified among the …

Nitrogen Efficiency and Regulation of Protein Synthesis in Lactating Dairy Cows
… environment and 30% or less is retained in milk protein. Plasma amino acids (AA) that are not used for protein synthesis in mammary glands (MG) are catabolized in post splanchnic tissues (liver plus gastrointestinal tract, pancreas, spleen, portal system, and associated adipose tissue) and two …

Evaluation of amino acid transport and protein metabolism in the mammary gland of dairy cattle
Improving our understanding of milk protein production regulation and AA transport is important for successfully formulating diets for AA and improving N efficiency. The objectives were to study protein synthesis regulation and AA transport using in vitro and in vivo models. In the first …

Evaluation of Corn Distillers Grains and Ruminally Protected Methionine and Lysine for Lactating Dairy Cows
… COG diets (28.7, 27.7, 29.4, 30.0 kg/d). Milk yield was improved with the COG diets (34.3, 34.0, 35.3, 36.7 kg/d) especially when COG diet was supplemented with RPML. Milk protein yield and percentage were improved by RPML. Milk fat yield and percentage were unaffected by diet. The only milk …

Protein enhancement of DDGS from conventional and enzymatic dry grind processes
… fiber were recovered prior to fermentation. Protein concentrate, protein isolate and sieving processes were applied to increase DDGS protein and decrease fiber contents. For conventional DDGS, protein contents of protein concentrate, protein isolate and sieved products were 33, 37 and 40%, …

Feeding Value of High Protein Oat Silage Versus Corn Silage for Dairy Cows
… in the United States it ranks highest in both protein and lysine content. Due to the wide genetic diversity of oat protein content, it seems possible to raise protein quantity in cultivated oat cultivars. Oat silage contains higher crude protein and a higher percent of digestible protein than …

An evaluation of supplemental methionine sources for lactating dairy cows
… of MP-Met to dairy cows to increase milk protein production is to feed rumen-protected Met ( RP-Met) products; however, not all RP-Met products are absorbed by the dairy cow in the same manner. Universally acceptable methods must be developed to determine the efficacy of different RP-Met …

The effect of rumen- protected protein and amino acids, and genetic milk casein polymorphism on dairy cows’ performance
… is a need to produce more food, particularly protein, to feed the growing population and lower hunger and diminish food insecurity. One of FAO (2018) targets is “ by 2030, end hunger and ensure access by all people, in particular the poor and people in vulnerable situations, including infants, …

Genetic and Environmental Responses of Harvest Index and Other Agronomic Traits in Winter Wheat (Triticum Aestivum L.) and Spring Oats (Avena Sativa L.)
… production, and growth rate, for improving grain yield. The effect of four nitrogen fertilizer treatments on harvest index, grain yield, grain protein percentage, grain protein yield, and total dry matter yield of wheat was evaluated for nine soft and three hard red winter wheat cultivars in 1979 …

Effects of pasture silage on yield and composition of milk from dairy cows
Factors affecting milk yield and composition were reviewed and it was concluded that feeding level and diet type (notably unwilted pasture silage) may have independent effects on yield and composition of milk. The objective of this research was to investigate the separate effects of forage type and …

USING ANTISENSE MESSENGER RNA TO DOWNREGULATE LON MEDIATED PROTEOLYSIS IN ESCHERICHIA COLI
… the introduction of foreign heterologous proteins into host cells, such as Escherichia coli. However, the metabolic burden incurred by the host cell to produce the desired recombinant protein elicits a cellular stress response that can result in reduced yields and degradation of the …

Effect of dietary protein degradability and fat on rumen, blood and milk components of Jersey and Holstein cows
… squares to investigate the effects of dietary protein degradability and supplemental fat on rumen, blood, and milk components. Diet dry matter contained 16% CP with two levels of rumen undegradable protein (RUP) obtained by substituting blood meal for soybean meal. Treatments were 29% RUP, 0% …

Effect of protein source on milk composition of cows fed low fiber, high grain diets
… > 75% TDN and ~ 16% acid detergent fiber. Milk yield was not different between treatments. Milk fat percent, milk lactose percent, and fat corrected milk yield were higher in cows on CG (3.13%, 5.30%, 23 kg) in contrast to cows receiving FM (2.11%, 5.00%, 20.5 kg). Milk protein percent was not …

Targeted expression of the anti-HIV microbicide lectin griffithsin in maize and tobacco
… variety of pharmaceuticals. Numerous therapeutic proteins have been produced in plant systems (Giddings et al., 2000; Ma et al., 2003). Protein based microbicides,-namely, neutralising antibodies and peptide lectins- lend themselves to production in plants (De Muynck et al., 2010; Matoba et al., …

Intensive spring nitrogen management of winter barley: silage and grain yield and composition
… and timing of spring nitrogen application on yield and composition of barley forage and grain and the fermentation and utilization of barley silage was investigated in a 3-yr study. The use of a growth regulator, ethephon, was also investigated. Nitrogen application at a rate of 135 kg/ha …
