the aim of this study was to evaluate the effects of feeding pistachio hull (ph) as a source of tannin and polyethylene glycol (peg) supplementation on feed intake, nutrients digestibility, milk yield and compositions, blood lipid metabolits and milk fatty acids profile in saanen dairy goats. nine maltiparus saanen dairy goats were used in a 3 × 3 replicated latin square design with 21-d period...
the aim of this study was to estimate genetic parameters of age at first calving and its relationship with productive traits of holstein dairy cows. a total of 24491 first lactation records (2x 305d) which were collected from 1995 to 2009 were used. the general linear model (glm) procedure was applied to determine effective factors on studied traits. herd-year-season (hys) and age at first calv...
The objective of this study was to determine the effect of different levels of sesame wastes (SW) on performance, milk composition and blood metabolites in lactating dairy cows. In this order, eight multiparous Holstein dairy cows were used in a replicated 4×4 Latin square design in four periods of 21 days. Treatments were control (no Sesame meal supplementat...

the aim of this study was to investigate the effects of different metabolizable protein levels in diet during the peri parturition on performance and blood parameters of afshari ewes and lambs. thirty two once lambing ewes in the last six weeks of pregnancy and the first six weeks of lactation with diets before and after parturition containing rates of nrc recommended and 20% higher one as low ...
The objective of this research was to evaluate the effects of monensin (MON), thyme (THY) and cinnamon (CIN) essential oils on dry matter and crud protein degradability characteristics of cottonseed meal, barley grain and corn silage, nutrient digestibility, and some plasma metabolites in Holstein steers (540 ± 35 kg initial BW) fed high-concentrate diets. Four rumen fistulated Holstein steer...
an experiment was conducted to evaluate the effects of dietary crude protein (cp) and lysine levels on performance and nitrogen excretion in broiler chickens. four hundred twenty 7-day old chickens from ross 308 strain were randomly allotted to 6 dietary treatments with 5 replicates of 14 chicks each (7 male and 7 female chicks). the cp levels were 17, 18, and 20 percent and lysine levels were ...
