The objective of the study was to evaluate feeding effect of microparticle protein derived from soybean meal and fish meal combined with Lactobacillus sp. at 1.2 mL on physiological condition of digestive tract and productivity of broiler. Total of 192 broiler, with initial body weight was 481.0 ± 67.2 g, given dietary treatment starting on day 21 until day 42. The experiment was assigned in a completely randomized design with 8 treatments and 4 replications. Dietary treatment were 21% intact protein (T0), 18% intact protein (T1), 21% microparticle protein (T2), 18% microparticle protein (T3), T0+Lactobacillus sp.1.2 mL (T4), T1+Lactobacillus sp.1.2 mL (T5), T2+Lactobacillus sp.1.2 mL (T6), T3+Lactobacillus sp.1.2 mL (T7). Parameters measured were total ileal lactic acid bacteria (LAB), Coliform and pH, rate of passage, daily body weight gain (DWG) and also carcass weight. Data were subjected to analysis of variance and followed by Duncan multiple range test (P<0.05). Experimental results showed that microparticle protein diet added with Lactobacillus sp. (P<0.05) increased total LAB and DWG, but decreased Coliform population, and slowed down the rate of passage. However, carcass weight was not significantly affected by treatments. Feeding microparticle protein (18%) with addition of Lactobacillus sp. (1.2 mL) can improve to be better condition of digestive tract based on higher LAB and lower Coliform populations, and increase daily body weight gain with the same carcass weight.

The Relationship

Blood samples were collected from five pregnant sows from day 111 postbreeding to farrowing and from their piglets at regular intervals between birth and 48 h. The time between birth and first suckling (BTS) was recorded for each piglet. Maternal serum testosterone (T) levels were detectable only at the beginning of parturition and were highly correlated (r = 0.83) with litter BTS. Serum T levels of male and female piglets were similar at birth. In male piglets the T levels increased to a peak 2 h after birth and decreased gradually thereafter. In contrast, the T levels of female piglets declined rapidly after birth to baseline levels. The BTS of female piglets was shorter than that of male piglets. Body weight of males was higher than that of females and was influenced by litter size. These results suggest that the higher serum T levels of male piglets may have a detrimental effect on their teat-seeking ability.

Background: Bisphenol-A [BPA, 2, 2-bis (hydroxyphenyl) propane] is widely used in the manufacture of polycarbonate plastic, water bottles, feeders , baby bottles, epoxy resins and inside coating in metallic food cans. Black seed oil (BSO) (Nigella sativa) commonly known as black cumin, reported to be beneficial in function of various systems in the body. The study was carried out to investigate the effect of BPA and BSO on body weight, lipid profile and serum glucose in male and female mice. Methods : A total of thirty (15 male and 15 female) Swiss Albino mice (Mus musculus), aged 25-28 days with an average body weight of 27.4±1g were randomly divided into 3 groups consisting 5 mice in each for each sex. Group A served as vehicle control. Group B was administered BPA @ 50 mg/kg bw daily, while group C received both BPA @ 50 mg/kg/day and BSO @ 1ml/kg/day respectively. Results: Data revealed that BPA treated mice showed slight increase in body weight gain while BSO controlled the weight gain in BPA treated mice. Cholesterol and LDL values were significantly (p<0.01) increased and Triglycerides value was significantly (p<0.01) decreased in BPA-treated mice without significant alterations in HDL value. BPA & BSO treated female mice showed significant (p<0.01) decreased in cholesterol, triglycerides and LDL values. BPA reduced the blood glucose level and addition of BSO had synergistic effects of glucose utilization. Conclusions: It can be concluded that BPA is one of the potential risk factors for hyperlipidemia and obesity. These harmful effects could be alleviated by the ingestion of black seed oil.

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.

The Relationship

Objective was to define a mathematical model that better explain the relationship of the animals weight depending not only on the animals age but also on the animals morphometric measurements. 40 piglets, half Duroc-Large White blood, were used, 20 males and 20 females, from 3 to 35 days of age (lactation phase) initially weighing 1.518 ± 0.121 kg and from 36 to 66 days of age (calving phase) with a body weight of 7.010 ± 0.704 kg. The animals were weighed weekly on a digital balance. The relationship of animal weight, age and morphometric measurements of male and female piglets were performed using regression models: existing, linear and power. The models were evaluated according to nine criterialinear model was the most adequate to explain the weight of male pigs, while for female pigs was the power. The age of the pig, the shank and palette length, as well as the circumference of the shank jointly explain the weight of the male piglets. The weight of females is explained jointly by age, body length, thorax and hip circumference.

Two trials were conducted with Nicholas strain turkeys. In trial 1, 300 male poults were reared to 49 days using either initial stages of 'large-turkey' feeding regime, or a situation allowing for diet self-selection of protein and energy. Within these programs, diets were supplemented with 10 ppm avoparcin, while a comparable number of controls received no growth promoter. Avoparcin improved growth rate (P < 0.01) irrespective of age, and improved feed utilization to 35 days of age. This effect was not confounded with the form in which diets were offered. In a second trial a 'broiler-turkey' feeding schedule was used, with birds slaughtered at 88 days. Diet treatments consisted of a control diet containing 33 ppm robenz and test diets containing either 33 ppm robenz + 10 ppm avoparcin or 10 ppm avoparcin alone. Avoparcin improved weight gain (P < 0.05) irrespective of coccidiostat inclusion. Feed utilization and carcass grades were not influenced by diet. The 7% improvement in body weight noted here with avoparcin was substantially greater than that previously observed with broiler chickens.

Rate of body weight gain of both the young chick and the young rat was markedly inhibited following ingestion of amounts of thyroxine which were greatly in excess of physiological requirements. The rate of body weight gain of the young rat was also markedly inhibited in alloxan diabetes. The administration of insulin partly or largely prevented the observed effect on body weight in both conditions. The administration of thyroxine caused a reduction of rat skeletal muscle mass which was partially prevented when insulin was given concurrently with thyroxine.Reduced body weight gain and muscle mass in the rat were accompanied by marked increases in the muscle DNA and nuclei concentration. Nuclear diameter and the amount of DNA per nucleus remained unchanged. RNA concentration of the muscle was not reduced. The beneficial effect of insulin administration on body weight and muscle mass was accompanied by a preventive effect against changes in muscle DNA and nuclei concentration. However, since the DNA content of muscle bundles remained relatively unchanged and since muscle bundle weights changed proportionately with body weight it would appear that DNA content does not reflect change in muscle mass.The effectiveness of insulin in the thyroxine-treated animal appears to be due to an improved utilization of energy. A hypoglycemic action of thyroxine implies an antagonism between the two hormones in their mechanism of action. The relationship between the two hormones is not direct since the administration of insulin does not affect the increased plasma protein-bound iodine levels resulting from thyroxine treatment.
