Milk Substitutes

The high demand for protein during this period of the calf's life is due to the active growth of muscle tissue, and protein is the structural material of all organs. A lack of protein in the diet of calves contributes to a delay in their growth and an excess to the expenditure of additional energy for the deamination of excess amino acids and the elimination of the corresponding decay products through the excretory system of the body. The younger the calves, the higher the protein level in their diet should be. The work aimed to establish the most effective protein norms in the composition of skim milk substitutes for calves over 65 days of age. The study of the influence of feeding skims milk substitute on calves' physiological state and productivity was carried out on four groups of bulls. All tested skim milk replacers varied in protein content but were almost the same in all nutritional parameters. The main ingredients of skim milk substitutes (ZOM 1) for calves of group I were, %: milk proteins – 70, vegetable proteins (soy + wheat) – 29, vitamin and mineral complex, probiotic culture – 1. For calves of group II (ZOM 2) used,%: milk proteins – 70, vegetable proteins (soy + wheat protein) – 29, vitamin-mineral complex – 1. protein) – 29, vitamin and mineral complex – 1. Studies have shown that skim milk substitutes in calves feeding, containing 20 and 22 % protein in the composition of KR-2 compound feed 10 % by weight, was reflected in the improvement of the morpho-biochemical design of the blood. At the same time, there is a tendency to an increase in the concentration of total protein in the blood serum by 3.1 and 3.3 % with a decrease in the amount of urea by 3.5 and 5.2 %, which made it possible to increase the average daily gain in live weight to 3.1 % while reducing costs feed and its price by 1.5 and 0.9 percent.

SUMMARYThe effects of temperature and method of feeding on the intake characteristics and digestibilities of two milk substitutes were examined.Forty Finnish Landrace x Dorset Horn lambs (20 males and 20 females) were fed one of two milk substitutes from 3 to 25 days of age when they were slaughtered and chemical composition of the empty body was measured.The two milk substitutes contained 30% fat in the dry matter as butter fat (diet B), or tallow and coconut oil (diet TC).The diets were offered at either 34°C (W) or 5 °C (C) and three methods of feeding were used. The diets were given: ad libitumcold (AL1), four feeds to appetite per day either warm or cold (AL2W and AL2C) and four feeds restricted to an intake of 62 g D.M./kg live weight0·5 either warm or cold (RW or RC).Digestibilities of the milk substitutes were not affected by the temperature at which they were offered or the feeding regime used. Diet B had an apparent dry-matter digestibility of 97·6% and diet TC 92·5%. The fat digestibility of diet TC was 13·6 units lower than diet B and this affected the digestibility of all the other dietary components.Lambs tended to consume more of diet B and grow faster.Lambs on treatment AL1 consumed 21% more milk substitute than those on treatment AL2.The composition of the body-weight gain was found to alter with rate of gain.The temperature at which the milk substitutes were offered had only a minor effect on the performance of the lambs. The type of milk substitute and feeding regime used had a greater influence on both lamb intake and growth.

Due to the impact of adverse environmental factors, unsatisfactory conditions of pig population, deterioration of food supply, abuse of antibiotics, lack of preventive measures, leads to the development of diseases among pigs, especially young, which leads to a decrease in resistance, body performance, reproduction and reduction of livestock, as well as large economic losses. The use of bacterial preparations from living microorganisms can significantly reduce or even eliminate the use of antibiotics and hormones in the cultivation of healthy animals, to obtain high-quality and safe high-grade products. The aim of the work is to study the effect of probiotic EM – 1 on the physiological state and productivity of young pigs of large white breed. The experiment was conducted on two groups (6 heads each) of animals-analogues, starting from 60 days of age, for 2 months. Animals of the control group received feed produced in the farm. Piglets of the experimental group in addition to the main diet received 5% of feed fermented with em-1. Evaluation of the physiological state and productivity of young pigs was carried out on 60, 90 and 120 days of experience according to the methods adopted in clinical practice. Hygienic, hematological, biochemical, zootechnical and statistical methods of research were used in the performance of the work. The use of probiotic EM-1 in animals of the experimental group led to an increase in hemoglobine concentration by 7.7%, an increase in the number of red blood cells by 13.7%, the total number of leukocytes by 9.52%, and glucose concentration by 11.4%. The advantage of the viability of these pigs for the content of total protein (P < 0.05), γ–globulins by 18.6%, the activity of aminotransferases (AlАT, AsAT; P < 0.05), the average daily gain increased by 12.3% at the end of the experiment. For feeding piglets feed with probiotic EM-1 increased metabolic processes, resistance and productivity of the body, which indicates a higher level of redox reactions in their body.

Block Experiment

ABSTRACTA total of 40 individually-penned British Friesian male calves were offered milk substitutes ad libitum from 2 days until 12 weeks of age. Ten milks were reconstitued from either liquid or spray-dried skim milk and a fat-filled (500 g fat per kg) powder and contained 80, 110, 140, 170 or 200 g dry matter (DM) per kg liquid. A further six calves were used in a randomized-block experiment to measure the digestibility, absorption and retention of the diets containing 80, 140 and 200 g DM per kg.There are no significant differences in the intake, growth rate, digestibility, absorption or retention between calves given milk substitutes reconstituted from liquid or spray-dried skim milk.At all ages, as the DM concentration of the milks increased, liquid intake decreased but DM intake and live-weight gain increased. The mean live-weight gain was 0·99, 1·13, 1·16, 1·28 and 1·27 kg/day for calves given the milk substitute diet at concentrations of 80, 110, 140, 170 and 200 g DM per kg, respectively. The DM intake to live-weight ratios were constant at all ages when live weight was expressed to the power of 0·61.No significant adverse effect of the diets was evident from the fortnightly monitoring of jugular blood samples for packed cell volume and concentrations of glucose, urea-N, Na, total protein, albumin, globulin and haemoglobin; nor from faecal consistency, rectal temperature, heart rate and respiration rate.There was no indication that age affected digestibility, except that digestive efficiency was reduced in calves with diarrhoea, particularly at 2 to 4 weeks of age; nor that dietary concentration influenced digestion or absorption. The true absorption of N, Ca and P from the milk diets was high with mean coefficients of 0·99, 1·01 and 0·95 respectively. The main endogenous losses of N and P occurred through the urine and of Ca through the faeces.

Today feeding disorders (deficiency of crude protein and limiting amino acids), the use of feed contaminated with microscopic fungi can lead to immune depression. When feeding dysfunctional feed, the live weight gain of young animals and fattening pigs is reduced by 10-90%, depending on the balance and completeness of the rations in terms of nutrients. The article assesses the degree of contamination of feed with microscopic fungi and studies the effect of eliminating the deficiency of crude protein, lysine and methionine on the health status and weight gain of laboratory rats when feeding moldy wheat grain. A balanced for essential amino acids feed allows reducing the stress of the body's defense system from the negative effects of saprophytes. An experiment was carried out on 200 (10 groups, n = 20) weaned rats of the Wistar line in order to comparatively study the consequences of feeding the diets containing wheat grain contaminated with fungi of the genera Aspergillus and Penicillium, deficient and balanced to the norms of the requirement for crude protein and two essential amino acids - lysine and methionine. The number of micromycete reaches 109 CFU (spores) in 1 gram of feed. These molds are dangerous because of the possibility of their spores entering the body of animals and germinating in the lungs, liver, kidneys, heart, intestines, reproductive organs, and muscle tissue. Once in the blood, mold spores spread throughout the body. A complete zootechnical analysis of grain was carried out in the toxicology laboratory using the methods of zootechnical and biochemical analyzes of feed, livestock products and metabolic products. The negative effect of microscopic fungi on the health indicators of white rats is less pronounced with a balanced diet for essential amino acids. A decrease in the tension of immunity, expressed in a decrease in T-cell deficiency and activation of phagocytosis, was determined. The average daily gain on the contaminated feed decreased by no more than 20%, while the gain on the contaminated diet was 50-60% lower.

As the byproduct of finger millet, millet straw is a new forage resource of ruminants. The effect of the combined utilization of millet straw with corn straw on fattening lamb production is seldom reported. The purpose of this study was to investigate the effect of different proportions of millet straw instead of corn straw on the growth performance, blood metabolites, immune response, meat yield, and quality of fattening lamb. Sixty-three-month-old healthy Small-Tailed Han sheep crossbred rams with an average initial weight of 19.28 ± 2.95 kg were randomly divided into four groups, with three replicates in each group and five lambs in each replicate. The replacement ratio of millet straw of each group (Group I, II, III, IV) was 0%, 25%, 35%, 50% at the first stage (the first two months) and 0%, 20%, 28%, 40% in the second period (final two months), respectively. The experiment lasted 4 months 10 days of the pre-feeding period. The results indicated that the body weight gain and average daily gain of group Ⅱ were significantly higher than those of group Ⅰ and group Ⅳ (p < 0.05). The concentration of total protein in group Ⅳ was significantly increased compared to those of the other three groups at the second stage (p < 0.05), which proved that the protein synthesis metabolism capacity was improved with the addition of millet straw. The concentration of the plasma glutamic-oxalacetic transaminase and lactic dehydrogenase of lambs was significantly decreased in group Ⅱ (p < 0.05). The combination of millet straw and corn straw had no impact on the glucose, total cholesterol, and triglycerides metabolism (p > 0.05). There was no significant difference in the pre-slaughter weight, carcass weight, dressing percentage, loin-eye area, and GR value among the four groups (p > 0.05). Furthermore, the immune response and meat quality were not impacted by the different proportions of millet and corn forage diets. The results showed that the combined utilization of millet straw with corn straw could improve the blood biochemistry metabolism capability of fattening lambs. The replacement of 50% of corn straw with millet straw could improve the growth performance and be an application in fattening lamb production.

Although milk substitutes attract a large subsidy from the EEC provided they contain at least 600 g skim milk solids/kg, several cheaper whey-based products have been Introduced commercially in recent years. Nevertheless, information on the nutritive value of such products is lacking. Since the calf is vulnerable to digestive upsets especially during the first month of life, an experiment was made to assess the effect on health and performance of replacing some or all of the skim milk solids with a mixture of whey powder and whey protein concentrate.Experimental Thirty-two Friesian bull calves in a randomised block experiment were given one of four milk substitute diets containing 200 g fat and 260 g crude protein/kg DM from 2 to 64 days of age. The reconstituted diets (1 powder:6 water, w/w) were offered to appetite twice daily by bucket at 38°C. The quantities of skim milk solids in each formulation were (g/kg DM): none (diet WP1), 200 (diet WP2). 400 (diet WP3) and 600 (diet WP4), as shown in Table 1. In vitro tests showed that coagulation with rennin did not occur with diets WP1 and WP2 and the clot formed with diet WP3 was much softer than that with diet WP4.

The article presents the data obtained as a result of carrying by employees of the Research Institute of sheep and goat breeding, a branch of the FSBSI "North Caucasus FARC", the scientific and economic experience to study the efficiency of a new fodder additive "Organic" on the productive and physiological indices of bull-calves during the completion of growing in the conditions of the farm "Pata" agricultural enterprise in the Karachay-Cherkessia Republic. The statement of the experience and all researches were carried out according to generally accepted methods. In the course of the experiment, the following indices were studied: the chemical compound of forages, the dynamics of a live weight gain in the experimental stock, hematological parameters, control slaughter data, economic indices. Completed researches have shown positive result from the use of the fodder additive "Organic" in bull-calves diets: an increase in the average daily gain of live weight by 25%, a slaughter yield by 1% and a high level of profitability – 27%. Thus, the additional introduction of "Organic" in a diet of young horned cattle in the 2nd experimental group promoted more intensive metabolism, stabilization of a physiological state, increase in productivity and, as a consequence, profitability of beef production. Researches in this direction reveal the latent fodder reserves promoting increase in the productivity of agricultural animals.

Mycotoxins have been formed in feed are secondary metabolites of fungi and are quite stable substances that have teratogenic, mutagenic and carcinogenic effects. An effective way to combat mycotoxins in feed is the use of feed additives that adsorb toxins, prevent their absorption in the gastrointestinal tract of the animal and are excreted from the body. The infl uence of coconut enterosorbent Shelltic Es on fattening and meat qualities of young pigs has been studied. It has been found in the process of fattening that the highest feed digestibility was in pigs of the experimental group, in the diet of which enterosorbent has been added. The results of studies of the chemical composition and technological properties of pork have been provided. The positive eff ect of enterosorbent on precocity, absolute average daily gain of live weight and reduction of feed expenditures per 1 kg of gain has been revealed. In pigs from the experimental group the average thickness of the fat was higher and the area of the “muscle eye” was lower compared with animals of the control group, which indicates that higher rates of carcass yield have been obtained due to faster accumulation of fat tissue. The weight of internal organs of pigs indicates the intensity of metabolic processes in the body. In experimental animals the weight of the lungs was 0,1 kg lower, and the liver and heart were higher by 0,13 and 0,01 kg, respectively. Enterosorbent had no effect on the content of vitamins in the liver of pigs of the compared groups. The content of impurities of organochlorine toxicants and toxic elements in the meat and liver of animals of the experimental group was lower than that of control analogues. Therefore, the use of enterosorbent Shelltic Es promotes more active excretion of them from the body.

Abstract BACKGROUND: A total of one hundred and forty, 28 d-old weaner pigs [Duroc x (Yorkshire x Landrace)] with initial body weight (BW) of 6.56±1.25kg were used in a six-week treatment (7 replicate pens per treatment; barrows, and 2 gilts/pen) to evaluate the effect of low nutrient density diet supplement with probiotic mixture supplementation on the growth performance, nutrient digestibility, fecal microbial, and gas emission of weaner pigs. RESULTS: Pigs fed low-density diet with probiotic mixture supplementation had linearly increased (P = 0.028, 0.014) the body weight (BW) at weeks 3, and 6. Moreover, average daily gain (ADG) was linearly improved (P=0.018, 0.014, 0.014) at week 3, 6, and overall experiment. However, there were no interactive effects found on the nutrient digestibility of dry matter (DM), nitrogen (N) and energy (E) throughout the experiment. Dietary inclusion of low-density diet with probiotic mixture supplementation has improved the fecal lactobacillus counts linearly, but E. coli was unaffected during the trail. On day 42, Ammonium gas emission was significantly decrease in pigs fed a low-density diet with probiotic mixture supplementation. However, H2S, acetic acid, and CO2 were not significantly affected by the probiotic mixture supplementation diet. CONCLUSION: Low-density diet with probiotic mixture supplementation had positively affected the growth performance, fecal microbial, and fecal gas emission on weaner pigs.

The aim of this study was to evaluate the effect of zinc (Zn) supplementation in different commercial forms on the growth performance, health status, and Zn balance of weaners in field conditions. The animals were fed pre-starter (from the 28th to 47th day of life) and starter (from the 48th to 74th day of life) mixtures differing in Zn form and concentration. Group I was given ZnSO4 at 150 mg kg−1; Group II received pre-starter zinc oxide (ZnO) at 3000 mg kg−1 and starter at 150 mg kg−1; and Group III was given 150 mg kg−1 of zinc oxide nanoparticles (nZnO). We found that the average daily gain in Group I was significantly lower, compared to Groups II and III. A commonly accepted level of Zn (150 mg kg−1) as nZnO can be recommended, instead of therapeutic doses of Zn preparations with the same efficiency. Moreover, a lower level of Zn in the diet can prevent the excessive accumulation of this element in waste and, thus, reduce environmental damage.
