EXCLUSIVE Free Tranny Animals



According to results of our study, incidence of health problems encountered in calving and after calving were found lower in FS. One of the reasons could be free movement choice for animal in FS barns. Freedom of movement in the group pen allows animals to freely express their natural instincts and behaviors, which is of particular importance for the total reproductive period (from first insemination to calving) (Sawa and Bogucki, 2011). A second reason could be the average age of cows in TS herds, although it was not evaluated statistically, there was a tendency to keep animals longer in TS herds included in this study. Reproductive disorders and reproductive performance are associated with age and older cows to have a higher incidence of RP than cows delivering their second and third calves (Muller and Owens, 1974). The third reason could be poor management practice relevant to feeding. Feeding errors are known to be the main factor in metabolic diseases like RP and poorer reproductive parameters of the cows (Stevenson, 2001).

The environment in which we keep our dairy cows has a dramatic effect on their health and welfare. Throughout the world, dairy cattle are managed under a wide variety of different housing systems and none of the systems are clearly superior although the FS systems have some advantages because of freedom of movement. However poorly designed stalls lead to reduced stall occupancy and the type of lying surface in the stall may affect some health and production problems (Calamari et al., 2009). There is not yet enough study regarding influence of resting surfaces and stall types on production diseases but as well-known increasing the softness of resting surface and proper stall type can increase the time that the cows spend lying down, which is an advantage for cow comfort, health and probably overall production. Deciding the kind of resting surface that is optimal for mastitis prevention and type of stall design which optimizes cow comfort and reduces the incidence of RB are the important questions about decreasing dairy herd turnover rates and improving cow health, production and longevity.


In past years Mr. Jones, although a hard master, had been a capable farmer, but of late he had fallen on evil days. He had become much disheartened after losing money in a lawsuit, and had taken to drinking more than was good for him. . . . His men were idle and dishonest, the fields were full of weeds, the buildings wanted roofing, the hedges were neglected, and the animals were underfed.


Every day Snowball and Napoleon sent out flights of pigeons whose instructions were to mingle with the animals on neighbouring farms, tell them the story of the Rebellion, and teach them the tune of Beasts of England.


After surveying the ground, Snowball declared that this was just the place for a windmill, which could be made to operate a dynamo and supply the farm with electrical power. This would light the stalls and warm them in winter . . . [The animals] listened in astonishment while Snowball conjured up pictures of fantastic machines which would do their work for them while they grazed at their ease in the fields or improved their minds with reading and conversation.


The skull of old Major, now clean of flesh, had been disinterred from the orchard and set up on a stump at the foot of the flagstaff, beside the gun. After the hoisting of the flag, the animals were required to file past the skull in a reverent manner before entering the barn.


So Beasts of England was heard no more. In its place Minimus, the poet, had composed another song which began: Animal Farm, Animal Farm, Never through me shalt thou come to harm! and this was sung every Sunday morning after the hoisting of the flag. But somehow neither the words nor the tune ever seemed to the animals to come up to Beasts of England.


It was a savage, bitter battle. The men fired again and again, and, when the animals got to close quarters, lashed out with their sticks and their heavy boots. A cow, three sheep, and two geese were killed, and nearly everyone was wounded. . . . But the men did not go unscathed either. . . . They saw that they were in danger of being surrounded . . . and the next moment the cowardly enemy was running for dear life.


Most airlines have specific requirements for transporting animals. It is recommended that you contact the airline well in advance to let them know you will be bringing your pet and to find out if you need to do anything before arriving at the airport, i.e. purchase a special pet carrier or obtain a health certificate from a veterinarian.

To study the role of downstream signaling by GDNF during the hair cycle and depilation, we conditionally deleted the signal transducing receptor, Ret, specifically within BSCs by generating K15-CrePR1:Retflox/flox mice (Fig. 4a). In this genetic model system, upon progesterone antagonist mifepristone exposure (topical 1% synthetic RU486), Cre recombinase is expressed in K15+ BSCs to initiate Cre-mediated excision of the floxed exons 14 and 15 of the RET kinase domain to generate non-functional RET30. As expected, in control K15-CrePR1:Ret+/+ mice we observed underlying pigmented skin and HFs at the second anagen stage (P29) of the hair cycle through histological means that also incorporated an ultimate 3D imaging of solvent-cleared organs (uDISCO) whole-mount clearing method (Fig. 4b, lower right panel)31. At 4 dpd (i.e., starting at P25), in control animals we observed the expected regrowth of anagen HFs (Fig. 4b, upper right panel). However, when Ret was conditionally deleted in BSCs during telogen (P19-21), the HFs remained at rest and failed to launch into the anagen hair cycle by P29 (Fig. 4c, lower right panel). Furthermore, Ret ablation within BSCs prevented the reconstitution of the lower HF after depilation (Fig. 4c, upper right panel). Histomorphometric analysis revealed a statistically significant decrease in the number of anagen HFs present both after depilation and at P29 within K15-Cre:Retflox/flox animals versus controls (Fig. 4d). qPCR analysis comparing 4 dpd skin samples derived from K15-CrePR1:Retflox/flox mice versus control samples in anagen confirmed the reduction in Ret and K15 transcripts after Ret deletion, and absence of mature HFs and differentiated cuticular keratinocytes through reduced Krt40 (keratin 40) mRNA levels (Fig. 4e). The qPCR analysis also revealed enhanced WNT (i.e., as shown by increased Lef1 and decreased Dkk2 expression) and reduced BMP (i.e., as evidenced by reduced Bmp4/Bmpr1a) signaling within RET-deficient skin (Fig. 4e), suggesting a comparable inhibition in the hair cycle. Interestingly, despite the BSC-specific RET-mediated defect in hair formation after depilation, individual HFs did retain melanin production (Fig. 4c, upper right panel, inset), presumably due to intact RET tyrosine kinase signaling within melanocytes26. As expected in K15-CrePR1:Ret+/+ control skin, immunofluorescence analysis revealed K15 expression predominantly within expanding BSCs along the proximal portion of actively growing HFs in depilated samples (Fig. 4f, left panel). However, BSC-specific Ret ablation resulted in punctate expression of K15 in addition to areas void of any K15 expression among individual hair follicles after depilation (Fig. 4f, right panel). Certain hair follicles also entirely lacked K15-expressing BSCs after depilation, suggesting a range of BSC effects upon Ret ablation (Fig. 4f, right panel). During the anagen stage of the hair cycle (P29), we observed the expected clusters of K15+ BSCs within control HFs (Fig. 4g, left panel). However, in K15-CrePR1:Retflox/flox HFs, we observed reduced numbers of K15+ cells within individual HFs at the expected anagen stage of the hair cycle (Fig. 4g, right panel). These results suggest that RET signaling within BSCs is required to germinate the lower HF to the next anagen stage.


In order to further characterize the cellular specificity of RET signaling during HF cycling and induced anagen development, we conditionally ablated Ret within both interfollicular basal epidermal keratinocytes and cells that make up the outer epithelial layer of HFs33. These cells express keratin 14 (K14) and play important roles in maintaining the lipid barrier as well as anagen development of HFs34. To ablate Ret within basal epidermal keratinocytes and outer epithelial cells of HFs, we generated K14CreERT:Retflox/flox mice and induced CRE-mediated recombination by administration of tamoxifen (Fig. 5a). At 11-days after synchronized anagen induction by wax depilation, we observed no difference in hair shaft formation as a macroscopic indicator of advanced anagen development between control and experimental K14-Ret-mutant animals (Fig. 5b, upper left panels). Similarly, histological analysis revealed that anagen progression was no different between control and experimental K14-Ret-mutant animals after depilation (Fig. 5b, upper right panels). Changes in the natural hair cycle were also investigated after Ret ablation within K14-postivie cells. Once again, we observed no difference in natural anagen development of HFs following tamoxifen treatment between control or K14-Ret-mutant mice both at the macroscopic and microscopic levels (Fig. 5b, lower panels). These observations were confirmed by quantifying the thickness of the skin, which is an indicator of the degree of anagen progression3 (Fig. 5c). Lastly, Cre-mediated deletion of the floxed Ret allele was confirmed via deletion PCR using harvested skin tissues (Fig. 5d). Overall, our data show that RET signaling within interfollicular basal epidermal keratinocytes and outer epithelial cells of HFs is not required for hair cycle progression and induced anagen development in postnatal mice. 041b061a72
