Two studies were conducted utilizing 270 chickens to evaluate the efficacy of yeast culture (YC) for both broiler and layer ayian types. In the first experiment, three dietary levels (0, 1.25, 2.50 percent) of YC were included in a nutritionally complete ration and fed to 14-day-old broiler chicks for 8 days. Body weight gain, feed consumption (g) and feed efficiency were not influenced by yeas...

The dairy cow has a well-recognized natural daily pattern of feed intake and milk synthesis, but regulation of these circadian rhythms has not been well described in the literature or well considered in current dairy management. Even when a total mixed ration (TMR) is fed, ruminal fermentation varies due to circadian variation in feed consumption, resulting in more fermentable substrate in the ...

Three adult human subjects were maintained for 7 days (period I) on a protein-free formula diet containing the minimum daily requirements of the eight essential amino acids plus 40 g glycine. During the last 5 days of this period, the average daily nitrogen balances for the three subjects were +0.52, +0.71, and +0.30 g, respectively. During the next 7 days (period II), valine was withdrawn from...

The growth and development of pigs is determined by their genotype environmental conditions (primarily the level feeding), however, number works aimed at studying complex influence genetic non-genetic factors in interaction currently insufficient. purpose our work was to estimate effect MC4R genotype, feeding these on backfat thickness crossbred investigate possibility correcting melanocortin-4...

The effect of dry season supplementation with crop-residue-based rations on bodyweight, scrotal circumference and serum testosterone concentrations in Red Sokoto weaner bucks at 5, 6 and 7 months of age was investigated in the present study. There were 7 treatment groups which were fed a positive control ration (conventional concentrate) fed at 1 and 2% of the bucks’ bodyweights (Rations 1A and...

Background: The usage of banana waste pseudostems has drawn more attention in recent years. Additionally, it is said that these components are rich vitamins and minerals, notably dietary fibre. objective this study was to investigate the effect substituting maize with sun dried pseudostem (BP) their feed on performances crossbred grower pigs. Methods: current carried out between 2020-2021 forty...

Regulation of the daily rhythm of milk synthesis is important to production animals and breastfeeding, but is difficult to observe in nursing animals. The rate of food intake varies over the day and is expected to create a daily rhythm of nutrient absorption. The objective of this study was to determine if the timing of food intake entrains a daily pattern of milk synthesis. Seventeen Holstein ...
