Gilts produce less colostrum with lower immunoglobulin G concentration than multiparous sows do. An extra dose of colostrum (30 mL) from multiparous sows was administered to piglets from gilts to ascertain its effects on performance and health in farm conditions, especially in the smallest piglets (birth weight < 1.100 kg; Q1). The control group (CON) consisted of 200 piglets from 18 gilts (50 smallest piglets) and 201 piglets from 16 gilts (52 smallest piglets) formed the supplemented group (SUP). Colostrum supplementation increased the homogeneity of weight (days 21 and 60) and average daily gain (ADG; days 0–10, 0–21, and 0–60) and a decreased use of antibiotics and mortality by diarrhoea (p < 0.05). SUP piglets showed better immune response (presence of antibodies, p = 0.033) against Mycoplasma hyopneumoniae (day 21), porcine reproductive and respiratory syndrome (PRRS; day 60), and influenza (day 60). In the smallest piglets, colostrum supplementation had important effects on mean weight in the first day of life (p = 0.009) and ADG until day 21 (p < 0.05). The smallest piglets had decreased the use of antibiotic treatment use when supplemented (p < 0.05). Colostrum supplementation can improve piglets´ performance and health, although doing so requires increased time and labour in maternity.

Vegetable oils are a source of natural antioxidants, including tocopherols, sterols, phenolic compounds, coenzymes, and polyunsaturated fatty acids that provide nutritional value, organoleptic properties, and significantly delay or prevent lipid oxidation. Eighty-four V-line rabbits at 5 weeks of age with an initial body weight (BW) of 535.60 ± 13.48 g were assigned randomly to four experimental groups (seven replicates in each group with three rabbits each). The first group served as a control and received 0.3 mL/kg BW of distilled water (CON), while the second and third groups received 0.3 mL/kg BW of rocket seed oil (RSO) and wheat germ oil (WGO), respectively. The fourth group received a mixture of oils consisting of 0.15 mL of RSO and 0.15 mL of WGO/kg BW (MOs). The experiment lasted 7 weeks. The study investigated the effects of RSO, WGO, and their mixture on growth performance, feed utilization, antioxidant status, and immune response of growing rabbits. The results indicated that the rabbits that were administered orally with RSO and WGO or their mixture had higher (p ≤ 0.05) final BW, weight gain, and average daily gain when compared to the control group. In addition, the feed conversion ratio improved significantly with RSO, WGO, and MOs treatments. Different oil treatments improved nutrient digestibility, nutritive value, and nitrogen balance. Moreover, the rabbits that received RSO, WGO, and their mixture had an improvement the meat fatty acid composition compared to the control rabbits. Oral administration of RSO, WGO, and their mixture significantly improved serum protein fractions, decreased blood urea nitrogen, and had a positive effect on serum total lipids, HDL-c, and LDL-c. Furthermore, the treatments of RSO, WGO, and MOs had a significant improvement in the antioxidative status and immune response.

Abstract Number of pigs born alive has been a key factor of the increasing efficiency of the U.S. swine industry. However, with increased pigs in the uterus, birth weight has been negatively impacted, with more small or at-risk pigs being born per litter. In order to overcome these changes, a study testing three commercial oral drenches against a control to determine which would increase average daily gain and decrease preweaning mortality. In a completely randomized design, 877 one-day-old suckling pigs from a high-health farm were selected for the experiment if they appeared to be in the bottom 20% of bodyweight compared to their contemporaries. Selected pigs were given one of four drenching treatments: 1) none (control), 2) bioactive proteins (BP), 3) high energy sugars (HES), and 4) immunoglobulins (IgY). Pigs were weighed on d 1 and d 19 of age (weaning), with mortality tracked during the suckling period. Data were analyzed using SAS v 9.4 (Cary, NC), with pig as the experimental unit and an accepted alpha of 0.05. Treatment had no detected effect on birth weight, weaning weight, ADG, or mortality (P = 0.79, 0.96, 0.86, 0.38 respectively). Likewise, statistical contrasts were used to determine there was no detected impact (P &gt; 0.10) of drench, regardless of type, compared to the control in any measured response criteria. Interesting, pigs drenched with BP or IgY had numerically lower preweaning mortality (11.2 and 11.5% respectively), than those administered the control or HES (15.4 and 15.2%, respectively). In conclusion, this experiment showed no significant difference in the performance between piglets given no product vs. those drenched with bioactive proteins, high energy sugars, or immunoglobulins. However, additional research is warranted with greater replication or disease stressors to better understand if oral drenches may improve preweaning performance or mortality in different situations.

The influence of feed additive "Ormik" consisting of organic acids (formic acid, lactic acid, orthophosphoric acid, acetic acid), as a filler of diatomite crumb, introduced into concentrated fodders, on the biochemical parameters of blood serum of pigs and on productivity is considered in the article. The studied feed additive was added to the feed daily in the form of loose powder, mixing thoroughly. The initial dosage of the feed additive in the 1st week was 1 g/kg of feed, 2nd week and the following – 3 g/kg of feed. The average daily gain in the live weight of pigs in the experimental group was 11,0% higher than the control group. The animals of the experimental group were less sick and the safety of this group was 100%, in the control group it was 90%.

For the last several decades, antimicrobial compounds have been used as feed additives to promote piglet growth at weaning, through the prevention of subclinical and clinical disease. However, few studies have assessed the influence of these antibiotics on the immune response of nursery pigs, as well as the relation between performance, health, and immunity of animals that receive feed additives. Therefore, the present study aimed to evaluate the effects of colistin and tylosin when used as feed additives on the performance, incidence of diarrhea, and immune response of nursery pigs. In this study, 72 weaned pigs (average age, 28 days) were allotted into one of three treatment groups: a control group (feed with no antibiotics), tylosin group (feed containing 22 ppm tylosin), and colistin group (feed containing 20 ppm colistin). Weekly, during a five week period, the average daily feed intake, average daily gain, and feed conversion ratio of the pigs were evaluated. Stools were scored daily, in accordance with a fecal texture scale. Blood samples were collected on the day of housing (d0) and on d7, d21, d28, and d35 for immune cell phenotyping. The results of this study showed that piglets in both the colistin and tylosin groups exhibited a significantly higher average daily feed intake, resulting in a higher body weight at the end of the experimental period (d35) when compared with piglets from the control group. Colistin and tylosin also significantly reduced the incidence of diarrhea. Colistin and tylosin modulated the piglets’ immune responses, particularly on d28, by changing the percentage of circulating B lymphocytes, CD4+CD8+ T cells, and the CD4:CD8 ratio.

The effect of using different levels guanidinoacetic acid in compound feeds on the growth of young quails meat direction of productivity. It is proved that adding to the basic diet of different levels guanidinoacetic acid (0.06, 0.12, 0.18 %) increases live weight of quails on 3.9 – 13.5 g and improves the absolute, average daily and relative gains compared to a bird in the control group, which were fed the main diet. The data show that at the age of 42 days of live weight was the highest in the diet of quail which was administered 0.12% GAA and dominant control of 13.5 g However, in 21 days live weight of quail fed 0.06 and 0.12 % guanidinoacetic acid was greater than control respectively 9.2 and 7.6 grams (P < 0.01). In absolute increments quail, fed GAA prevailed bird control group. The largest absolute increase was in birds that consumed the main diet of GAA level of 0.12% and prevailed controls 6.5 g (P < 0.001). A similar situation was of average daily gain. Young animals that received feed containing 0.12% guanidinoacetic acid had the highest average growth, which exceeded 0.9 g (15.5%) bird control group. As for the relative performance increases here were different. The lowest relative growth observed in birds which were administered GAA 0.06%, it lagged behind the controls 0.1 g in the same period quail treated with 0.12 and 0, 18% guanidinoacetic acid superior control respectively 2 and 1.1 g.

Abstract This study evaluated changes in performance of bulls enrolled in the Utah Beef Improvement Association’s (UBIA) annual performance tests conducted in accordance with central bull test standards established by the Beef Improvement Federation. Breeds with over 500 bulls enrolled over the period of 2004 to 2018 were included in the evaluation. The breeds with greater than 500 animals evaluated included the Angus, Red Angus, Hereford and Simmental Breeds. Traits evaluated included birth weight, initial weight, a 205-day adjusted weaning weight, final test weight, average daily gain, adjusted yearling weight, and weight per day of age. The mixed model procedure of SAS and interval regression analyses were utilized to evaluate the yearly rate of change for each breed and to determine if that rate of change was significantly different (P &lt; 0.05) between the evaluated breeds. When evaluating all breeds represented across years, significant differences (P &lt; 0.05) were observed for rate of change when evaluating birth weight and 205-day adjusted weaning weight. However, no differences were observed between breeds with more than 500 animals represented. Significant differences (P &lt; 0.05) for rate of change were observed when comparing the top four represented breeds, for average daily gain, initial test weight, final test weight, adjusted yearling weight and weight per day of age. Specifically, a declining trend was noted for all breeds when evaluation all significant traits. When evaluating the previously described traits, the Angus breed was significantly different in its rate of decline when compared to the Red Angus and Hereford breeds. The lone increasing trend was observed in the Hereford breed which had a positive increasing trend for initial test weight which was significantly different (P &lt; 0.05) from both the Angus and Red Angus breeds but not significantly different from the Simmental breed.

Phytogene feed additives (phytobiotics) are plant origin compounds used in animal nutrition in order to improve their productivity by improving the production performance of animals, feed properties and the quality of food of animal origin. These additives stimulate animal growth by using their natural and physiological potentials and mechanisms providing conditions for the realization of the genetically projected production volumes. Data on the use of phytobiotics as growth stimulators are incomplete and often very contradictory, especially those related to their impact on the health and performance of weaned pigs. Given the relevance and importance of these issues the feeding trial was organized by the group-control system. The experiment lasted for 40 days and it was divided into two phases of 20 days each. Trial was conducted on 24 piglets, F1 generation of Swedish Landrace and Pietrain, weaned from sows at the age of 35 days. Tests were carried out on piglets, with an average body weight of 8.61?1.59 kg, which were subjected to one of the two feeding treatments immediately after weaning. The control group was fed with a mixture without growth promoters, while the experimental group received a diet containing preparation of phytobiotic (Enviva EO 101, Danisco Animal Nutrition) in the amount recommended by the manufacturer (0.1 kg/t). The mixtures for piglets nutrition were formulated in accordance with the recommendations of the NRC (1998), and AEC (1993) and they met the nutritional requirements completely. During the experiment, there was no disturbance of health and/or the manifestation of clinical signs of disease. The control group, fed with the diet without added growth stimulators, achieved body weight (25.32?6.31 kg), average daily gain (0.42?0.12 kg), consumption (0.89 kg) and feed conversion (2.119 ) normal for a given race, age and housing conditions. The use of preparation of phytobiotics as growth promoters, led to better production results in regard to the control group, which was based on higher body weight (27.19?4.77 kg), higher average daily gain (0.46?0.09 kg) and better feed conversion (2.043). The use of phytobiotic, as an alternative option in growth stimulation of weaned pigs, has its nutritive, medical and economic justification.

Spraying yearlings with 2% Co-Ral in July was 100% effective for systemic control of cattle grubs (Hypoderma spp.). Spraying spring calves with 1% Co-Ral in August was equally effective, and gave better control (P < 0.01) than spraying with 1 or 2% Co-Ral in June or 0.5% Co-Ral in July. Co-Ral sprays were not suitable for horn fly (Haematobia irritans L.) control.Two per cent Sevin sprayed on calves in June or July did not control cattle grubs, and only partially controlled horn flies.Compared with the control group, the average daily gain was higher (P < 0.05) to weaning but lower (P < 0.05) in the feedlot in calves sprayed with 2% Sevin in June. Similarly, it was higher (P < 0.05) from birth to the end of the feedlot period in calves sprayed with 2% Co-Ral in June, but lower (P < 0.05) in calves sprayed with 0.5% Co-Ral in July.Mild toxicosis occurred in five calves sprayed with 2% Co-Ral in June, and subclinical toxicosis in calves sprayed with 1% Co-Ral in August.

A study was conducted to evaluate the effectiveness of Synovex® H as an agent for prenatal androgenization in beef cattle. Thirty Charolais-cross heifers, exposed to a fertile bull during a 55-d spring breeding season, were randomly assigned to a control group or implanted with three times the normal dose of Synovex® H between days 20 and 75 of gestation. Serum concentrations of testosterone, estradiol, and progesterone, calving rate, and growth performance were determined in the pregnant heifers. Testosterone levels were greater (P < 0.001) in treated heifers than in control heifers. Synovex® H treatment had no affect on estradiol levels. Progesterone levels were lowered (P < 0.05) in treated heifers. Synovex® H treatment decreased (P < 0.05) calving rate and birth weight of calves born to treated heifers. Calving ease scores were not affected by Synovex® H treatment. Weight was not affected; however, average daily gain was improved 7% by Synovex® H treatment (0.88 vs. 0.82 ± 0.04 kg d−1, treated and control heifers, respectively). These results are interpreted to suggest that Synovex® H is not an appropriate androgenizing agent for cattle due to adverse effects on progesterone concentrations during pregnancy and on calving rate. Key words: Cattle, prenatal androgenization, Synovex® H, pregnancy, hormones

Twenty-six of 52 heifers with an average liveweight of 318 kg were dewormed by intraruminal injection of oxfendazole and placed in drylot on 31 January. The other 26 animals served as controls. All heifers were pastured starting on 14 June and the treatment heifers were dewormed in the same manner as at the start of the experiment (31 January) on 1 July and 31 July. The groups started out with similar total worm eggs per gram of fecal sample, but the dewormed heifers had fewer counts each month thereafter. The drylot average daily gain of the treated heifers was higher (P = 0.01) and less variable (P = 0.12) and by 29 May these animals were heavier by 11.7 kg (P = 0.10). The treated animals did not gain as fast on pasture (P = 0.20), but the gain continued to be less variable (P = 0.09). Age at puberty was not different. Number of open heifers in the treated group was 4 vs. 15% for the control group (P = 0.18). Deworming by intraruminal injection resulted in faster feedlot gains, more uniform gains during both drylot and pasture, reduced parasites and no abscess at injection sites. Key words: Anthelmintics, oxfendazole, cattle, heifers
