This study tested the effect of neck rails equipped with and without foam on stall usage and preference by dairy cows. The hypothesis of the experiment, that cows prefer lying stalls with foam in comparison to stalls without foam, was rejected. There was no significant difference (p > 0.05) in lying time and time spent standing with two and four hooves in the lying stalls between the two treatment groups. Considering the time of individual stall occupation and the distribution of stalls in the pen, cows showed a preference for one of two lying stall rows. Analysis of variance showed a significant difference (p < 0.001) between the time of stall occupation for the two different rows in the pen, including the time spent lying and the time spent standing with two and four hooves in the stall. Lying time per stall in the preferred row (near the feeding alley) in comparison with the alternative row was 580 ± 101 min·d−1·stall−1 versus 50 ± 28 min·d−1·stall−1, respectively. These results can support a design process for new barns with a free-stall housing system for dairy cattle.

Recent Developments

This paper provides an overview of recent developments in rearing conditions, health and welfare issues of dairy cows. The last approximately 30 years has witnessed worldwide increasing scientific research, consumer activity, and political response towards housing condition, health and welfare issues of dairy cattle. All buildings and housing systems for dairy cattle should be designed, constructed, maintained and managed to assist in the achievement of the Five Freedoms: freedom from hunger and thirst, freedom from discomfort, freedom from pain, injury and disease, freedom to express normal behavior and freedom from fear and distress. Whether dairy cows are housed in cubicles, straw yards or cow sheds, in order to maximize their performance and to ensure satisfactory standards of welfare, the accommodation must provide the most basic behavioral and physiological needs. As an absolute minimum, the housing must provide a comfortable, clean, well drained and dry lying area together with shelter from adverse weather. Also, it must allow the cow to move freely around without risk of injury and certain diseases. If the housing system does not provide for these basic needs, then not only will health, welfare and production of dairy cattle be compromised, but it is likely that failure to comply with the welfare codes and the law relating to animal welfare will occur.

Tujuan dari penelitian ini menganalisis pengaruh serbuk kunyit dan kurkumin pada jumlah dan ukuran sel spermatogonium; spermatosit primer; dan spermatosit sekunder; bobot testis serta diameter tubulus seminiferus Mus musculus yang diberi minuman beralkohol. Penelitian ini merupakan penelitian eksperimental dengan Rancangan Acak Lengkap (RAL), menggunakan 12 ekor Mus musculus jantan yang dibagi kedalam 4 kelompok perlakuan dan 3 kali ulangan. R0 merupakan kontrol, R1 kontrol alkohol, R2 pemberian serbuk kunyit sebanyak 0,1 mg/hari, R3 pemberian kurkumin sebanyak 0,01 mg/hari. Perlakuan diberikan selama 30 hari. Data penelitian dianalisis menggunakan analysis of variance (ANOVA) pada taraf kepercayaan 95%. Berdasarkan hasil penelitian yang diperoleh dapat disimpulkan bahwa tidak terdapat perbedaan bermakna (p>0.05) pada jumlah spermatogonium dan ukuran sel (spermatogonium, spermatosit primer, dan spermatosit sekunder), namun terdapat perbedaan bermakna pada (P<0,05) pada bobot testis, diameter tubulus seminiferus dan jumlah sel (spermatosit primer, dan spermatosit sekunder). Turmeric contains curcumin compounds that can be used as anti-inflammatory substances and help repair damaged cells. The purpose of this study was to analyze the effect of turmeric powder and curcumin on the number and size of spermatogonia cells; primary spermatocytes; and secondary spermatocytes; testicular weight and diameter of the seminiferous tubules of Mus musculus given alcoholic beverages. This study is an experimental study with a completely randomized design (CRD), using 12 male Mus musculus which were divided into 4 treatment groups and 3 replications. R0 is control, R1 is alcohol control, R2 is 0.1 mg/day of turmeric powder, R3 is 0.01 mg/day of curcumin. The treatment was given for 30 days. The research data were analyzed using analysis of variance (ANOVA) at the 95% confidence level. Based on the results obtained, it can be concluded that there is no significant difference (p>0.05) in the number of spermatogonia and cell size (spermatogonia, primary spermatocytes, and secondary spermatocytes), but there is a significant difference (P<0.05) in testicular weight, diameter of the seminiferous tubules and the number of cells (primary spermatocytes, and secondary spermatocytes).

Gene Frequency Distribution

The serum transferrin type was identified for 1102 dairy cows. The gene frequency distribution among nine herds of predominantly Friesian type cattle was TfA 40.7 per cent, TfD 55.9 per cent, and TfE 5.4 per cent. In one herd of 31 Red Poll cattle the distribution was TfA 32.3 per cent, TfD 33.8 per cent, and TfE 33.8 per cent. There was no significant difference between the observed and expected distribution of the various genotypes. Cows of genotype D/D produced significantly more milk than those of type A/A, but their butterfat test was lower and the average butterfat production of the two groups was identical. There was no significant difference in lactation length.

Dietary Treatments

An experiment was conducted on early lactating dairy cows to study the effect of rumen protected choline (RPC) and methionine (RPM) on milk yield and composition. Fifteen crossbred dairy cows in early lactation (within 10 days of calving) were selected and randomly allotted to any one of the following three dietary treatments, T1 (Control)- with compound feed mixture containing CP- 20% and TDN- 68% , T2- T1+20g RPM and 20g RPC, T3- with compound fed mixture containing CP- 17%, TDN- 68% + 20g RPM and 20g RPC. All the experimental animals were fed as per ICAR feeding standards (ICAR, 2013). Results revealed no significant difference (p>0.05) in milk yield and 4 per cent fat corrected milk (FCM) yield between the three treatment groups. Among the milk constituents, animals in T3 had significantly higher milk fat (p<0.05), SNF (p<0.05), protein (p<0.05) and total solids (p<0.01) compared to those in T1 and T2. Milk urea nitrogen levels did not differ significantly among the three treatments and were within the normal range. The study showed that milk composition could be effectively improved by supplementing feed with rumen protected forms of choline and methionine in combination at lower dietary protein level without any reduction in milk yield.

Over Time

The up-to-date literature suggests that the compost-bedded pack barn housing system is capable of remarkably improving productive and reproductive performance, as well as health status and welfare, in dairy cattle. However, there is currently limited knowledge available on the endocrine and biochemical changes in animals housed in such alternative systems. Therefore, this study aimed to measure blood cortisol (COR) and beta-endorphins (BE) in 22 two-year-old primiparae Fleckvieh cows, who were randomly allotted to the following two different housing systems: CB (n = 11) and FB (n = 11). Blood samples were collected at the beginning of the experiment (T0) and every two months thereafter (T1, T2, and T3). The COR and BE were measured through an immunoenzymatic kit. With the only exception being T0, no differences were observed over time between the two groups, neither for COR nor for BE. However, the blood cortisol levels of the CB cows decreased over time, while a T1 peak was identified in the FB group. On the contrary, both the housing systems displayed numerically higher BE at T3 than at the other experimental times. Therefore, the overall data suggest that the compost-bedded pack barn did not significantly affect the studied parameters. Accordingly, cow welfare should be assessed using a wider panel of animal-based indicators.

AbstractIntroductionThe American Heart Association (AHA; Dallas, Texas USA) and European Resuscitation Council (Niel, Belgium) cardiac arrest (CA) guidelines recommend the intraosseous (IO) route when intravenous (IV) access cannot be obtained. Vasopressin has been used as an alternative to epinephrine to treat ventricular fibrillation (VF).Hypothesis/ProblemLimited data exist on the pharmacokinetics and resuscitative effects of vasopressin administered by the humeral IO (HIO) route for treatment of VF. The purpose of this study was to evaluate the effects of HIO and IV vasopressin, on the occurrence, odds, and time of return of spontaneous circulation (ROSC) and pharmacokinetic measures in a swine model of VF.MethodsTwenty-seven Yorkshire-cross swine (60 to 80 kg) were assigned randomly to three groups: HIO (n=9), IV (n=9), and a control group (n=9). Ventricular fibrillation was induced and untreated for two minutes. Chest compressions began at two minutes post-arrest and vasopressin (40 U) administered at four minutes post-arrest. Serial blood specimens were collected for four minutes, then the swine were resuscitated until ROSC or 29 post-arrest minutes elapsed.ResultsFisher’s Exact test determined ROSC was significantly higher in the HIO 5/7 (71.5%) and IV 8/11 (72.7%) groups compared to the control 0/9 (0.0%; P=.001). Odds ratios of ROSC indicated no significant difference between the treatment groups (P=.68) but significant differences between the HIO and control, and the IV and control groups (P=.03 and .01, respectively). Analysis of Variance (ANOVA) indicated the mean time to ROSC for HIO and IV was 621.20 seconds (SD=204.21 seconds) and 554.50 seconds (SD=213.96 seconds), respectively, with no significant difference between the groups (U=11; P=.22). Multivariate Analysis of Variance (MANOVA) revealed the maximum plasma concentration (Cmax) and time to maximum concentration (Tmax) of vasopressin in the HIO and IV groups was 71753.9 pg/mL (SD=26744.58 pg/mL) and 61853.7 pg/mL (SD=22745.04 pg/mL); 111.42 seconds (SD=51.3 seconds) and 114.55 seconds (SD=55.02 seconds), respectively. Repeated measures ANOVA indicated no significant difference in plasma vasopressin concentrations between the treatment groups over four minutes (P=.48).ConclusionsThe HIO route delivered vasopressin effectively in a swine model of VF. Occurrence, time, and odds of ROSC, as well as pharmacokinetic measurements of HIO vasopressin, were comparable to IV.BurgertJM, JohnsonAD, Garcia-BlancoJ, FultonLV, LoughrenMJ.

Three-hundred and eighty-five serum samples were taken from dairy cows on 90 farms in 12 counties from the northern region of the Paraná State, Brazil. The samples were analyzed by IFAT for the detection of anti-Neospora caninum and anti-Toxoplasma gondii IgG antibodies. Forty-five (12%) samples were seropositive to N. caninum, while 102 (26%) samples were seropositive to T. gondii. Only four animals were seropositive to both coccidia. No significant difference was observed between the N. caninum serology and any of the variables studied, such as dairy cattle management, milk production, reproductive problems, feeding, and presence of dogs, cats and rodents. These data suggest that neosporosis is present among dairy cattle in the studied geographic region and the simultaneous detection of serum positive animals to both types of coccidian parasite demonstrates the independent occurrence of these coccidia in dairy cows.

This case study aims to determine the effect of a combination of prostaglandin F2α (PGF2α) with Gonadotropin (PG-600), and human chorionic gonadotropin (hCG) on the estrus and pregnancy rates in Holstein Friesian (HF) cows with persistent corpus luteum (PCL). A total of 15 Holstein Friesian (HF) dairy cows aged 3-5 years with body condition score (BCS) 5-7 (scale 1-9) diagnosed with PCL, were injected with 7.5 mg PGF2α intra-vulvar submucosa. Cows were then divided into three treatment groups. Group P0 was not given the combination treatment, while P1 group was injected with a  combination of 300 IU PG-600 and 150 IU hCG, meanwhile P2 group was was injected with a combination of 300 IU PG-600 and 300 IU hCG intra-muscularly. The PGF2α and PG-600 injections were carried out on the same day PCL was diagnosed. Meanwhile, the injection of hCG was carried out at the same time as the AI. The Pregnancy examination was performed 90 days after AI through rectal palpation. The results showed that all treated cows were estrus  observed with the fastest onset of estrus was the P2 group, that was significantly different (p <0.05) compared to the P0 and P1 groups. All treated cows were diagnosed as pregnant. It can be concluded that the administration of PGF2α or its combination with gonadotropins in HF cows with PCL could result in 100% estrus and pregnancy rates.
