When does are taken to mate some are ready for mounting, while others show lordosis, cornering and circling. Naloxone treated does were notably calm during handling and mating and behavioral scores were lower compared with saline treated does (P=<0.05It It was concluded that the endogenous opioid system in White New Zealand rabbit does, facilitate sexual behavior and reproduction.

The objective of this work was to determine the productive indicators of MEVEZUG breed lambs, 12 lambs of 22±3.04 kg of average live weight were randomly selected. The lambs to integrate in treatment 1(SP), feed consisted of grain corn, soy paste, native grass hay and mineral salts. In the treatment 2 (SPU), the feeding was similar to that of the SP, with the addition of urea, the variables were: dry matter ingestion (DMI), daily weight gain (DWG), feed conversion ratio (FCR) and yield in hot carcass (YHC), yield empty carcass (YEC), primary carcass cuts (PCC); the data were analyzed by ANOVA, comparison of means Duncan test with 5% probability (P< 0.05), according to the statistical package InfoStat. The DMI, DWG, FCR, YHC, YEC, cavitary fat in relation to live weight and PCC, had the following values: 1.038 kg, 0.271 kg, 3.831, 43.5%, 51.17%, 2.8% and 12.6 kg respectively and 1,058 kg, 0.247 kg, 4,284, 43.6%, 51.6%, 3.2% and 13.18 kg in SP and SPU respectively, these values were statistically similar with the exception of the FCR (P˂0.0001). It is concluded that the studied indicators were similar in the two treatments, with the exception of the FCR.

In Senegal, the alternation between a short rainy season (3 months) and a long dry season (9 months) results in strong qualitative and quantitative variations in the nutritional value of fodder which rarely responds to the demands of the animals throughout the entire season. year. This work contributes to studying the technicoeconomic effects of energy and nitrogen supplementation on the weight performance of Peulh Peulh rams. It involved a total of thirty (30) rams with two adult teeth, with an initial average live weight of 27.04 kg distributed according to a random device in six (6) groups of 5 subjects kept in permanent stabling. The six (6) batches of animals each correspond to six (6) food treatments composed respectively of untreated straw (control) (T0), untreated straw + multinutrient blocks (T1), untreated straw + the processed feed (T2), untreated straw + multinutrient blocks + milled feed (T3), 5% urea treated straw (T4) and urea treated straw + milled feed (T5) . The results showed that over the three months of testing, including the adaptation phase, the energy and nitrogen supplementation of the rams significantly increased the live weight (PV), the mean daily gain (ADG), the mean ingestion. individual straw (IMIP) and individual water consumption (IEC) in subjects. The best average daily gains were in decreasing order of importance recorded in lots T5, T3, T2, T1, T4, T0 (control lot). However, the results showed that the weight performance of the rams having received the T1 and T4 treatments was superior to that of the T0 control treatment, but this difference is not significant (p> 0.05). The rams having benefited from the T5, T3 and T2 treatments had statistically superior weight performances (P <0.05) to others. Likewise, the T4 treatment is economically more profitable than the others.

The effects of dietary intake of humates on the proteolytic, amylolytic and cellulolytic activities in the intestine of broiler chickens Ross 308 (starting weight 37.79 ± 0.58 g) were analyzed. Three experimental (A, B, C) and one control groups of birds (n=120) were fed with mixtures Hyd1 236.0 (day 1 - 10), Hyd2 222.40 (day 11 - 30), Hyd3 193.30 (day 31 - 42) g.kg-1 crude protein. Humates (HM or HN) were added into feed mixtures: A group – 0.7% HM containing an absorbent of mycotoxins, B group – 0.7% HN without the absorbent, C group – 0.3% HM and the control without humates. There were measured body weights and feed consumption, as well as the average daily weight gains and the feed conversion ratio, were calculated once a week. On one hand, the positive effects of 0.7% humates were observed on the increase (P <0.05) of proteolytic on day 21 (B) by 7.92 (azocaseing.ml-1.min-1.g-1), cellulolytic on day 28 (A) by 0.89 (glucose mol.l-1.min-1g-1) in the intestine of broiler chickens measured in the excrement. On the other hand, the decrease (P <0.001) of amylolytic activities was observed on day 33 (A) by 1.58 and (B) by 1.43 (glucose mol.l-1.min-1g-1). In the case of intake of 0.3% humates, the proteolytic or cellulolytic were decreased in C on day 21 or 28 by 16.39 and 2.41, respectively. The recommended level of added humates into a feed of chickens is 0.7%.

The most common problem in agricultural industry is the contamination of corn with zearalenone.Zearalenone may cause humans and animals intoxications. It is often a cause of the disruption the breeding process with consequent economic losses. The aim of this work was to determine the incidence and concentrations of zearalenone (μg/kg) in corn samples using enzyme-linked immunosorbent assay (ELISA). Incidence of zearalenone in corn samples achieved 46.4 % (13 maize samples) with concentrations range 69.897 – 1531.617 μg/kg and average value 399.578 μg/kg. The detected levels of zearalenone did not exceed the maximum acceptable limits of 3,000 μg/kg.

Intrammamary infections – mastitis and prepartum immune suppression are almost associated with endocrine changes and decreased intake of critical nutrients. Among the most important antioxidant nutrients but often deficient in compound feeding stuff are vitamin E (VTE), and selenium (Se) compounds.The aim of the experiment was to study Seand VTE sources in the diet of dairy cows in late phase of pregnancy and their effects on udder health and milk quality during the first two weeks after calving. The experiment included 40 cows of Slovak Pied cattle divided into two equal groups (n = 20). The first group (D)was peroral supplemented with addition of 0.3 mg Se/kg in anorganic form of sodium selenite and 50 mgVTE in form of dl-α-tocopherol acetate/kg of DM given from 6 weeks pre partum to parturition (total dose of 5.0 mg Se/kg and 1020 dl-α-tocopherol acetate/kg of DM per day). The control group (C) was without peroral supplementation of Se and VTE with the diet containing 0.2 mg of Se and 56 mg VTE/kg of DM.In supplemented group were observedincreased plasmatic concentrations of Se and VTEon the day of parturition and on the 14th day of lactationas well as increased activity of glutathione peroxidaseimmediately after calving.In addition to increased plasma levels, a 12.5% reduced incidence of clinical mastitis was observed in the supplemented group during the first two weeks after calving.

A group of does (n = 10) received 0.5 mg NX at 12 hr. intervals two days before and two days after mating, a control group (n = 10) was sham treated with saline injections. After kindling, kints born, nursing time and kint growth was studied. NX treated does nursed their kints for 235 ± 11.3 secs vs controls 220 ±16.2 secs (P<0.05). Milk yield and Kint weight was significantly higher in naloxone treated does.Kints born from control and naloxone treated does was 10.1  1.1 and 12.13  0.77 (P<0.05). Kints born live from naloxone treated and control dams was 11.3  0.94 and 9.5  0.9 (P<0.05). NX treated does weaned 10.0  0.9 kints, controls 8.7  1.05 (P<0.05). It was concluded that endogenous opioids are important modulators of nursing behavior in rabbit does favoring the development of their young.

In order to demonstrate a certain resistance / varietal tolerance against the fall armyworm, Spodoptera frugiperda, J.E. Smith (1797) (Lepidoptera: Noctuidae), three varieties of maize were tested under agro-ecological conditions I and II of Togo. From October 2019 to January 2020 at the Tchitchao agronomic experiment site the Ikenné, Obatanpa and Sotubaka varieties were tested using a complete random block device with four replicates. The infestation of the plants by the pest occurs naturally and the data (number of egg clusters, fresh droppings, larvae, leaf damage) were collected from the 10th to the 59th day after sowing (DAS). The results showed that the three varieties are already infested on the 10th DAS with peak rates of infestation between the 17th and 24th DAS but the Ikenne variety remains significantly more infested than the other two from the 24th to 59th DAS. Also, the leaf damage observed on the Ikenné variety was significantly higher than on the other two varieties Obatanpa and Sotubaka (P <0.0001) themselves. The different varieties tested have an influence on the incidence of the fall armyworm. The varieties could be used in integrated pest management programs against the fall armyworm.

Recently, it was discovered that swine acute diarrhea syndrome may replicate in primary human cells, particularly human lung and intestinal cells, according to certain publications. These findings suggest that viruses from poultry and animals, which have a broad host range, should be given more attention. Infectious illnesses of cattle pose a serious danger to human life as well as the country's economic development. In this post, we give a quick introduction of some of the challenges surrounding cattle infectious illnesses.
