The effects of repeated anthelmintic treatment with levamisole on body weight gain of grazing calves on the Atherton Tablelands are reported. On six farms, calves treated up to 10 times at 3-week intervals with 1.9 mg/kg or 7.5 mg/kg levamisole injected subcutaneously gained up to 37 and 59 kg more than untreated calves grazing the same pasture. Significant differences ( P < 0.05) were found in cumulative weight gains of calves given high doses of levamisole from 18 weeks and at low dosage from 24 weeks compared with untreated controls. The helminths mainly responsible for the reduced weight gain were Haemonchus placei, Oesophagostomum vadiatum and Coopevia species (C. pectinata and C. punctata). Seasonal incidence of nematode egg counts showed an increase in the proportion of H. placei eggs following wet and warm conditions, and O. vadiatum eggs following wet and cool conditions. Untreated calves developed natural resistance to helminth infection as measured by reduced faecal nematode egg counts after 6 months of natural challenge. One-quarter recommended dose of levamisole at 3-week intervals resulted in approximately half the weight gain advantage produced by full dose treatment except in the drier areas of the Tableland, where a higher advantage was recorded at this level.

Poultry farming holds a special place in ensuring the products that the consumers demand, it provides the population with essential food products,such as eggs and meat,that contain vital micro and macronutrients, proteins, lipids, and vitamins. Therefore, the issues of rational, economically feasible feeding of meat poultry, namely broiler chickens, are an urgent task. It is also essential to find effective methods of their application in order to correct the natural resistance and immune and biological reactivity of birds. The purpose of this research is to study the effect of the biological stimulant-Nucleostim on the growth and development of chickens, hematological, and immunological parameters of the blood of birds.This Biostimulant is a purified bovine spleen extract containing at least 1 mg / ml of low molecular weight peptides (nucleotides and nucleosides) formed as a result of autolysis, using dry whey and diatomite as fillers. Onthe application ofNucleostim, the gain in live weight of chickens was increased by 9.7%. At the end of the experiment, the livability of the chicks of the experimental group treated with Nucleostimcame up to 88%, compared with the 72% of the control group. The use of biostimulant had a stimulating effect on the liver of chickens confirmed by the research results presented in the article, as well as contributed to the development of the thymus in the setting of general dystrophy. Thus, it improved chicklivability and increased body weight gain. The biological stimulant-Nucleostim as an adaptogenic, anabolic, and immunostimulatory agent is promising for finding new drugs that improve the health and productivity of poultry.

Milk Feeding

Thirty-two male Holstein calves, beginning at 1 wk of age, were used to estimate differences in weight gain between two feeding levels and two feeding frequencies over a period of 3 wk. Calves were randomly assigned to one of the following four treatments: whole milk (WM) fed at 10% of body weight (BW) twice a day; WM fed at 10% BW, three times a day; WM fed at 12% of BW, in two feedings per day, or WM fed at 12% of BW, in three feedings per day. Body weight gains and feed conversions were 279 and 437 g per day and 12.02 and 9.51 kg whole milk per kilogram of gain for the 10 and 12% levels of feeding, respectively. There was a trend towards increased rate of gain and improved feed efficiency when calves were fed twice compared to three times a day. Cost of medication was not influenced by level or frequency of feeding. It was concluded from this study that feeding whole milk at 12% of body weight was preferable to feeding at the 10% level of intake. Key words: Milk feeding, level, frequency, dairy calves

Feeding Trials

Ayrshire bull calves were utilized in two feeding trials with the following treatments in factorial design: indoors vs. pasture, whole milk vs. milk-replacer, 3 or 4 lb starter daily to 15 weeks of age in the first trial and 2 or 3 lb in the second. All calves received the same treatment after 15 weeks, fall pasture and winter drylot.The average daily body weight gain from 1 week of age to weaning at 130 ± 2 lb was 1.05 lb and did not differ appreciably among treatments. Starter intake was increased markedly by indoor and (or) milk-replacer feeding. Calves receiving milk-replacer indoors consumed an average of 1 lb starter per day; calves fed whole milk on pasture ate only 0.4 lb starter per day. Weight gains from weaning to 15 weeks of age on pasture were 1.5 lb/day for calves weaned from whole milk, and 1.2 lb/day for those previously fed milk-replacer. Starter levels had little effect on the performance of the pasture — whole milk group. Indoor rearing compared with pasture rearing during this period significantly decreased calf gains, the greatest reduction occurring from milk-replacer and (or) low starter level. Calf performance to 1 year of age did not differ as a result of preweaning liquid diet, starter levels, and in the first trial initial rearing environment (1.4 lb/day). The 2-lb starter level significantly decreased yearly gains for calves initially reared indoors compared with pasture.
