Monensin and mineral supplementation economically increase yearling cattle weight gain on California annual rangeland

Stocker operators generally graze cattle on California annual rangelands from November to May. The profit margins of these operators is low as cattle sell for less per unit at the end of the season when compared with the beginning. This creates a need for methods to economically increase weight gain, which can help to mitigate market volatility. The use of monensin is common in much of the United States but has not been researched in the unique winter annual rangelands of California. Likewise, research that formally documents weight gain from the correction of selenium deficiency on these rangelands is also lacking. Trials were conducted over 2 years to determine weight gain differences with treatments of salt only (control), salt with monensin, mineral supplement, and mineral supplement with monensin. All three treatments increased weight gain by 12%, 9%, and 15% over feeding straight salt, respectively. It appears that selenium deficiency correction and supplemental monensin should be considered economical weight gain improvement tools for yearling cattle grazing California annual rangeland.

Pengaruh Mengkonsumsi Multiple Micro Nutrient (MMN) Terhadap Peningkatan Berat Badan Ibu Hamil

MMN, Weight. Pregnant women are one of the vulnerable groups may suffer from anemia because of events that occurred hemodelusi sat pregnancy. MMN is a supplement that contains multivitamins, iron and folate given to pregnant women as one of the Indonesian health ministry programs in an effort to prevent anemia during pregnancy. MMN order to determine the effect on weight gain for pregnant women. The research method to experiment with randomized. The population of 24 male mice. Twenty rats were given MMN. Data analysis using independent t-test. Results: Based on the average value MMN can increase weight gain. There is a difference in weight gain between before and after given MMN.

Effect of different levels of digestible lysine on performance, and blood parameters of male and female broilers in the starter period

Lysine is the reference amino acid (AA) in the ideal AA ratios for chickens. Feed formulation based on digestible AA has been shown to increase weight gain and feed intake and improve body composition in broilers. Amino acid (AA) in most feed ingredients will not be totally digested, and knowledge of such efficiency is important in formulating diets and will be used to eliminate differences in absorption efficiencies due to feedstuff sources. This study was conducted to evaluate the growth performance and blood parameters of broilers fed various levels of DL (Digestible Lysine) supplemented in diets from day 1 to day 18.

Normal food intake and growth in hyperprolactinemic rats

Normal lactation, a state of chronic hyperprolactinemia, is often accompanied by increased food intake. Two recent reports suggested that, in rats, prolactin (PRL) administration or chronic endogenous PRL excess led to increased food intake and growth. Similar methods of achieving augmented circulating levels of PRL in rats have been employed in our laboratory. Rats with extra anterior pituitary (AP) grafts under the kidney capsule have chronically elevated circulating PRL levels. However, in several experiments, weight gain, food intake, and fecal weight were the same in AP-grafted rats and in control muscle-grafted rats. In addition, the AP-grafted rat model was modified to demonstrate that PRL-induced increases in adrenal glucocorticoids and decreases in estrogens did not provoke alterations in eating behavior. Injection of homologous PRL for 8 days did not increase weight gain in normal or hypophysectomized rats. These data suggest that neither the chronic PRL excess caused by AP grafts nor the acute PRL excess caused by rat PRL injections increases food intake or weight gain.

Alkane-grown yeast in relation to selenium in broiler diets.

In a trial, 1080 male chicks, 15 per cage, were given a basal diet low in selenium or diets with 12.5 or 25% of G-yeast grown on alkane-type hydrocarbons. All diets were supplemented with vitamin E 10 and antioxidant 100 mg/kg and each diet was supplemented with Se at 0.1, 0.25, 0.5, 0.75 or 1 mg/kg. There was a significantly negative linear effect of yeast on bodyweight, weight gain and a significantly positive linear effect on feed conversion efficiency up to 7 weeks of age, indicating that the G-yeast caused a depression in comparison with the control. The supplements of Se did not increase weight gain or feed conversion efficiency but increased contents of Se in breast and leg muscle at 7 weeks. The contents of Se in muscles of the broilers on the basal diet were rather high, presumably because of a carry-over from the hen via the egg.
